One, the application status of stone curing agent

Stone as a high-end decoration materials, has been more and more used in building decoration industry. The use of stone protective agent can obviously improve the stone after the existence of various diseases, it is the most effective measures to prevent the occurrence of various diseases, and can effectively protect the stone, prolong the service life, and enhance the decorative effect. Industry products and policies related to the industry have been in the chemical industry, stone industry and construction industry began to develop simultaneously.

Two, stone curing agent product classification

There are many types of stone curing agent, and a variety of different classification:

According to solute composition can be divided into: methyl silicate, acrylic type waterproof agent, silicone protective agent (acrylic resin and silicone compound), silicone type protective agent (YISHION silicone compounds based silane, silicone, etc.), fluorinated silicon type (organic silicon and fluorine compounds as the main active ingredients).

According to the function can be divided into: breathable type (of the elephant skin, like a respiratory function, environmental pollutants can penetrate into the stone, and stone and outer interface of gaseous water can freely), sealed (closed).

Protective effect can be divided: waterproof type F can prevent water and water pollutant infiltration stone, do not form a significant drops, can be mixed with cement mortar used in, enhanced adhesion), hydrophobic (water on the surface of the stone formation obviously drops, prevent solid, liquid, vapor, water and water pollutant infiltration stone), anti oil (to prevent water and oily contaminant infiltration stone interface and waterproof).

According to solvent state can be divided into: water (in water as the dispersion medium), oil (in order of organic solvent as the dispersion medium), emulsion type. Paste. Powder.

According to the action mechanism can be divided into: permeability, surface film type.

According to the use can be divided into: surface protection agent (for the stone surface protection), the bottom of the protective agent (for wet plaster stone of the bottom surface protection), six face full of care.

According to the decorative effect can be brightening type (can deepen color stone), stone Zengguang (can increase the gloss), color type (keep the stone colors).

From the development stage of the stone curing agent, through several stages. The first generation of wax, the second generation of acrylic resin, the third generation of acrylic resin and silicone silicone acrylic compound, the fourth generation of methyl silicate, the fifth generation of pure organic silicon compound.

Three, stone maintenance team

Now some of the stone processing enterprises, stone business, stone decoration enterprises, real estate development company, stone professional maintenance company and the construction team are engaged in stone processing and pathological processing. But they know little about the knowledge and treatment process of the waterproof curing agent of stone material. The stone protection project is considered to be able to take it for granted or by experience. Some even think just deal with the type of a layer of paint can enticingly or lifetime, and some even one-sided think stone without maintenance water-proof, and only for Tooley but the cheap curing agent on the stone were coping with the maintenance, also has many enterprises only stone facade waterproof maintenance, and don't do stone bottom surface and the side surface of the waterproof maintenance. These circumstances in the stone conservation and construction in general, have restricted the development of stone maintenance industry. The main reason is the lack of understanding of the understanding of stone conservation, and no mature stone curing agent and industry standards and strict inspection standards. Therefore, the need to improve and improve the area is also particularly.

Four, the domestic development trend

At present, China has not set up a stone protection industry national and industry standards, the new stone protection agent industry recommended enterprise standards are also being developed. Therefore, the performance of the protective agent is still only measured by the performance of the stone. At present, the most effective testing items of stone material is water absorption ratio, which is an important indicator of the quality of stone protective agent. Next is the anti fouling performance, as there are cement pull test (i.e., the impact of the bond strength test).
