The two-component polyurethane waterproof coating belongs to a two-component chemical reaction curing type waterproof material. The first component is an isocyanate-terminated prepolymer obtained by polycondensation of polyether and isocyanate, and the second component is a plasticizer, curing agent, Colored liquid composed of thickener, accelerator and filler. When used, mix the two components of A and B in proportion, and paint on the surface of the waterproof base layer, often cross-linking and curing at a temperature, forming a rubber-like elastic coating film, so as to play a waterproof role.

One-component polyurethane waterproof coating is a reactive moisture-curing polymer waterproof coating. It is based on isocyanate and polyether as the main materials, and is mixed with various latent solidifiers, plasticizers and other additives. The process is formed by high temperature dehydration and polymerization. When used, it is coated on the waterproof base layer, and the chemical reaction between the -NCO end group in the polyurethane prepolymer and the air in the air forms a tough, soft drink and seamless rubber waterproof film on the surface of the base layer.

The advantages of the steel structure building are many, the material is light, the installation is convenient, and some components can be reused. Especially under the influence of the country's vigorous promotion of energy saving and emission reduction, the application of steel structure in the construction field is getting larger and larger, so how long is its service life? This varies according to different regions. The next is 6-8 years, and the inland area is almost 10 years. If it is in an area with dense industrial and mining enterprises, its life will be shortened. Some have leaked less than three years after installation, what is the reason?
Because this material is light and has poor wind resistance, it needs to be reinforced with a large number of screws. At the same time, it will cause artificial damage. We all know that the top layer of steel structure building is a layer of metal composite plate, the thickness should be a few millimeters thick, and its long service life is mainly determined by the anti-rust paint coating on its surface. It is greatly affected by changes in the environment and temperature. The coefficient of thermal expansion and contraction are large, and the anti-corrosion paint coating is damaged. The metal plate below will be rusted up to three years, and leakage will occur.
Color steel tile metal roofing special waterproof coating, using exposed special emulsion plus high-quality pigments and fillers, made by a series of chemical reactions with UV aging resistance, high and low temperature resistance, high adhesion, high solid content, An exposed waterproof coating with excellent tensile strength and elastic recovery rate, especially for complex parts such as assembly seams, reinforcement screws, vents and other complex parts with special reinforcement materials, waterproof and anti-seepage effect very good. The construction is simple, spraying, brushing and scraping are available, and the color can be customized according to the actual situation on site.

● Cement-based permeable crystalline waterproof material is a gray powdery material formulated with ordinary Portland cement as the base material and mixed with active chemical components. Cement-based permeable crystalline waterproof material, its waterproof mechanism is mainly porous. Under the action of water, the waterproof material contains active chemical substances, using water as a carrier. As water penetrates into the pores of the structure, the active chemical substances The water penetrates into the interior and reacts to form insoluble crystals such as ettringite. The active chemical substance and the unhydrated cement particles undergo a hydration reaction, and promote the cement hydration, forming cement hydration crystals, generating a large number of crystal filling, sealing The pores are blocked so that water cannot enter the concrete, thereby achieving the purpose of waterproofing.
● Cement-based permeable crystalline waterproof material, due to its good adhesion, whether it is a light base surface and a wool base surface, a back water surface and a water facing surface, a dry base surface and a wet base surface, or a stagnant water base surface does not affect its construction effect .
