The definition of stone protectant is stone protection, which means that some protective agents are brushed, sprayed, coated, rolled, drenched and soaked, so that the stone protective agent is evenly distributed on the surface of the stone or penetrates into the interior of the stone to form a kind of protection, so that the stone It has the functions of waterproof, anti-fouling, acid and alkali resistance, anti-aging, anti-freeze-thaw, anti-bio-erosion, etc., thus achieving the effect of improving the service life and decorative performance of the stone. B, water-based protective agent: stone curing agent that can be dissolved by water is called water-based stone protective agent. Such as water-based protective agents, water-soluble solvent-based protective agents, emulsion-type protective agents. Such protective agents generally have a relatively low penetration (except for water-soluble solvent-based protective agents), but the toxicity and odor are relatively small and non-combustible. Suitable for the protection of loose stone surfaces. A. Film-forming protective agent: A protective agent that stays on the surface of the stone after application and forms a visible film layer is called a film-type protective agent. Such as: acrylic type protective agent, silicone-type protective agent, silicone type protective agent. It is mainly used for the protection of non-polished surface stone surfaces.

classification:
Stone protectant is a liquid specially used to protect stone, mainly composed of solute (active ingredient), solvent (diluent) and a small amount of additives. In recent years, as the rapid development of the building decoration industry has promoted the rapid growth of the stone protection industry, the protective agent market has become unprecedentedly prosperous, with dozens of varieties and increasing trends. In order to facilitate the correct differentiation and use of the majority of users, Shanghai Hongben Stone Maintenance Co., Ltd. combines many years of experience to divide stone curing agents into several categories according to their different ingredients, properties, characteristics and uses. I hope to give you some reference value. .
Classified by their protective purposes
It can be divided into two major types of waterproofing agents: water-repellent and anti-fouling. It is a liquid material that can provide waterproof protection to stone and prevent stone from being damaged by water.
Antifouling agents are liquid materials that prevent the stone from being damaged and contaminated by water and other liquid contaminants such as juice, cooking oil, oil, dyes, and the like.
Classified by active substance
It can be divided into silicate protective agent, silicone oligomer protective agent, acrylic protective agent, organic fluorosilicone protective agent and organic fluorocarbon protective agent.
I. The silicate-based protective agent on the market is mainly an aqueous solution containing an inorganic silicate as an active ingredient, and it is one of the earliest silicone protective agents.
II. The silicone oligomer-based protective agent is a protective material in which a silane monomer or a siloxane oligomer having a small molecular structure or a mixture of the two is used as an active material.
III. Acrylic or silicone resin protective agent is made of acrylic resin as a coating to protect the treated stone interface. Usually use some rough stone surface, like fire surface, because the pores on this kind of stone surface are completely open and very susceptible to pollution. In addition, it is also used in the bottom of the stone for sealing treatment, which can effectively prevent the wet stone from returning to the alkali water spot.
IV. The organofluorosilicone type protective agent is a multifunctional protective agent synthesized by utilizing the low surface characteristics unique to organic fluorine and the small molecular structure of silicone.
V. The organic fluorocarbon resin-based protective agent is a new-generation stone protective agent, which makes full use of the extremely low surface tension of organic fluorine, excellent weather resistance and anti-pollution and oil-discharging effect, and is especially suitable for high-end villas, bars, clubs, and five-star hotels. Wait.
Classified by diluent
Can be divided into solvent-based stone protectants and water-based stone protectants.
I. Solvent-based stone protectant is a stone protectant with silicone or organosilicon fluoride as active material and some petroleum solvent or other chemical solvent as carrier.
II. Water-soluble stone protectant is a stone protective material with water as solvent. According to the different active ingredients, it is divided into silicate and silicone emulsion protection agents.
Classified by processing substrate
Can be divided into general purpose and special type
I. Universal type, can be used for most stone such as granite, marble, sandstone, slate, cultural stone and so on.
II. Special-purpose protective agent specially designed for the characteristics of various stone materials, such as marble special protective agent specially designed for the characteristics of marble which is not resistant to acid and soft texture. It is specially designed for granite which is difficult to penetrate and easy to change color. Protective agent, special for sandstone special protective agent for sandstone loose and long, high water absorption, easy to freeze and thaw, prone to yellowing and blackening, especially for the bottom protection agent with cement wet and easy to return alkali Stone sealant), specially used to increase the gloss of rough surface stone (fired noodles, lychee noodles, machine knocking noodles, mushroom noodles, antique noodles), specially used for treating stone color difference and changing stone texture of stone brightener.
III. Quick-drying type, a quick-drying protective agent designed for the low temperature in the north and catching up with the project.
Classified by solvent type
A, water-based protective agent: completely water-based diluent protective agent called water-based protective agent. This kind of protective agent generally has less odor, low toxicity, no burning, and high safety performance.
B. Solvent-based protective agent: A protective agent that uses a solvent other than water as a diluent is called a solvent-based protective agent. It can be further divided into water-soluble solvent-based protective agents and oil-soluble solvent-based protective agents. A water-soluble solvent refers to a type of solvent which is completely compatible with water. Such as alcohols; oil-soluble solvents refer to a class of solvents that are compatible with oily substances but are not compatible with water. Such as benzenes, ketones, esters and the like. The protective agent using a water-soluble solvent as a diluent is called a water-soluble solvent-type protective agent; the protective agent using an oil-soluble solvent as a diluent is called an oil-soluble solvent-based protective agent. Solvent-based protective agents generally have a strong odor, relatively high toxicity, flammability, and general density.
C, emulsion type protective agent: using oil-soluble solute and water as a diluent, adding emulsifier and stirring at high speed. Its color is milky white, the smell is small, non-combustible, and the toxicity is relatively small.
Classified by solubility
A. Oily protective agent: A protective agent that can be dissolved by an oil-soluble solvent is called an oil protective agent. Such as: oil-soluble solvent protective agent. Such protective agents generally have strong penetrating power, but are relatively toxic, flammable, and have a strong odor. Suitable for the protection of stone front and dense surfaces.
Classified by protection use
A. Bottom stone curing agent: It is specially used as a protective agent for stone floor protection treatment. It does not form an interface and does not affect the bonding of stone and cement. Some protective agent formulations also have bonding substances added to increase their bonding. strength. These protectants mainly include some hydrophilic silicone and film-forming protective agents.
B. Surface stone curing agent: It can not be used as a protective agent for stone bottom protection treatment, and generally has a hydrophobic effect. When used, it should be selected according to different finishes, mainly oily stone protective agent and some water-based stone protective agent.
C. Special curing agent for special stone varieties: a protective agent specially used for the protection and treatment of certain stone types.
D, general-purpose stone protective agent: a protective agent suitable for protective treatment on any surface of all stone materials. Such as hydrophilic silicone stone curing agent, fluorosilicon type stone curing agent.
Classified by protection effect
A. Waterproof type protective agent: After application, it can prevent water from penetrating into the interior of the stone, and also has anti-fouling (partial), acid and alkali resistance, anti-aging, anti-freeze-thaw, anti-bio-erosion and other functions. Such as acrylic, silicone C and silicone type stone protectants.
B. Anti-fouling type protective agent: It is a protective agent specially designed for anti-fouling of stone surface. Its function mainly focuses on anti-fouling performance, and other properties and effects are general. Such as vitrified brick surface antifouling agent.
C. Comprehensive protective agent: In addition to excellent oil, anti-fouling and anti-aging properties, it also has all the functions of waterproof stone protectant.
D. Professional protective agent: a protective agent specially developed for the special function requirements of stone surface glazing and color enhancement. Such as color-enhanced stone protective agent, enhanced stone protective agent. 
Its performance is a basic indicator of the performance of the protective agent. It indicates the waterproof ability of the stone, indicating the extent to which the stone protectant is applied to the stone to cause a change in the water absorption rate of the stone, which is usually expressed by water repellency. From the existing materials and technology, the waterproof performance index should be better at 80-90%. Of course, since it is a gas permeable material, it is unrealistic to be 100% waterproof.
