B. Silicone-type protective agent: The protective agent of acrylic resin and silicone compound as the main active ingredient (solute) is called silicon-acrylic stone protective agent. This product is a transitional product developed from silicone protective agent to silicone protective agent, which solves the shortcomings of acrylic acid easy to yellow and short life. It is the second generation of improved products, such as: "Green Angel" HB-S501, 502 and so on.
C. Silicone type protective agent: The protective agent which uses silicone as the main active ingredient (solute) is called silicone type stone protectant. Commonly used silicones are sodium methyl silicate, methyl silicate, silane, siloxane, etc. These protective agents are characterized by a network of silicone chains, strong penetrability, and venting, no change. Stone color. The disadvantage is that the oil resistance is poor. Suitable for any surface treatment of all stone materials. Silicone stone curing agent is the main product type on the market and belongs to the third generation. For example: "Green Angel" HB-S103, 302, 401, 503, etc.
D. Silicon fluoride type: The protective agent of silicone and fluorine compounds as the main active ingredient (solute) is called fluorosilicone stone protectant. This product inherits the advantages of silicone and enhances oil, stain and aging resistance. It is the best protection product at present.
Artificial stone products. It is a fourth generation product suitable for any surface treatment of all stone materials with special protection requirements. For example: "Green Angel" HB-S201, 202, etc.
(4) Classification by action mechanism
Artificial stone film-forming protective agent
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. For example: "Green Angel" HB-S501, 502, 601, etc.
B. Penetrating protective agent: After application, the active ingredients are all infiltrated into the interior of the stone by capillary pores. The protective agent with no visible film on the stone surface is called osmotic stone protective agent. Such as: silicone type protective agent, fluorosilicone type protective agent. Suitable for all stone surface protection. For example: "Green Angel" HB-S101, 301, 402, etc.
(5) Classification by interface force
A. Water-repellent stone protective agent: After use, it will enlarge the tension between the surface of the stone and the water (tension is greater than the adhesion), which can make the water roll on the surface of the stone, which can be reflected on the surface of the surface. However, the effect of this effect is very short, and it will quickly fade with the loss of the effective components of the surface. The final effect is the water resistance and water pressure resistance of the protective agent. This type of protectant is mainly oily, and some waters also belong to this category. For example: "Green Angel" HB-S302, 501, etc. The hydrophobic stone protective agent can not be used for the bottom protection of the stone, because its hydrophobic property will form an interface between the stone and the cement, which will affect the degree of bonding and make the stone appear empty.
B. Hydrophilic stone curing agent: After use, the tension between the surface of the stone and the water will not be enlarged (the adhesion is greater than the tension), the water can be uniformly adsorbed on the surface of the stone, and there is no effect of rolling the water ball, but it does not enter the interior of the stone. . The effect of this protective agent is also the main
Artificial stone is determined by its water resistance and water pressure resistance. Hydrophilic protective agents are mainly some waterborne waterborne protective agents. For example: "Green Angel" HB-101, 103, 103A, etc. The hydrophilic stone protectant can be used for the six-sided protection of the stone. When the bottom surface is protected, the interface will not be formed, and the adhesion will not be affected, but it will not increase. Because the penetration is not strong, it cannot be used for the protective treatment of dense structures.
(6) 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. For example: "Green Angel" HB-S601 and so on.
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. For example: "Green Angel" HB-S201, 302, 401, etc.
C. Special curing agent for special stone varieties: a protective agent specially used for the protection and treatment of certain stone types. Such as: HB-S103A special protective agent for sandstone, special protective agent for white linen.
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.
