So far, China's new waterproof material industry has gone through more than 20 years of development and has achieved gratifying results. Under the new economic situation, how should China's waterproof material industry go? What new type of waterproof material should be developed? Everyone will discuss and discuss together.
Synthetic polymer waterproof membrane consolidate the application of PVC and EPDM waterproof membrane, promote the formation of a polyethylene polypropylene (polypropylene) waterproof membrane and polymer cement bonding system, accelerate the research and development of wet-laid self-adhesion Into a polymer waterproofing membrane, limiting the use of chlorinated polyethylene waterproofing membranes, eliminating reclaimed rubber waterproofing membranes.
Waterproof coating Consolidate the application of polyurethane waterproof coating, polymer cement waterproof coating, cement-based waterproof coating, cement-based penetration crystalline waterproof material and silicone waterproof coating, development and application of sprayed polyurea polyurethane waterproof coating, research and application of high solid content water-based asphalt Waterproof coating, promotion and application of road and bridge waterproof coating and other special purpose waterproof coating. It is forbidden to use contaminated coal tar waterproof coatings.
The polymer modified bitumen membrane is used to consolidate the application of SBS, APP modified bitumen membrane and self-adhesive rubber bitumen membrane, and the development of wet-laid self-adhesive modified bitumen membrane is promoted. Repelling coils, actively applying glass fiber asphalt shingles, restricting the use of composite bitumen waterproofing membranes and paper tar mats, and prohibiting the use of coal tar sand-surface waterproofing membranes.
The sealing material consolidates the application of acrylate sealing material (mid-range), strongly promotes the use of high-grade sealing materials such as poly*, silicone, and polyurethane, and actively researches the use of special primers for sealing materials to improve the adhesion and water resistance and durability of sealing materials. . It is forbidden to use plastic grease, PVC cement and other sealing materials.
Waterproofing agent consolidates the application of general-purpose water repellent, advocates M1500 water-based penetration waterproofing agent and permanent condensate (DPS), and promotes the use of silicone waterproofing agent and fatty acid waterproofing agent. Restrict the use of water repellents with high chloride ion content and prohibit the use of powdered water repellents with excessive alkali content.
Waterproof mortar actively uses polymer cement waterproof mortar, promotes polypropylene fiber (PP) and nylon fiber and wood fiber anti-crack waterproof mortar, and researches the application of zeolite-like siliceous waterproofing agent. Vigorously promote the use of commercial mortar (waterproofing, heat preservation, antisepsis, cementation, filling and self-distribution of special mortar).
Grouting material foundation reinforcement uses cement-based grouting material, structural reinforcement uses cement-based epoxy grouting material, especially low-viscosity moisture curing epoxy grouting material, waterproof plugging uses ultra-early self-leveling grouting cement and polyurethane, acrylate grout material. A composite grouting process is recommended for different engineering conditions. It is forbidden to use toxic and contaminated grouting materials such as propidium chloride.
Waterproof and heat insulation materials Consolidate the use of extruded, molded polystyrene board and mortar exterior insulation systems, and actively promote the use of spray polyurethane rigid foam body waterproof insulation material, the appropriate development of the application of plastic powder polystyrene insulation mortar system. Limit the use of heat-absorbing materials such as expanded vermiculite and expanded perlite. Do not use loose material insulation.
Bentonite waterproof material is actively applied natural waterproof material - sodium bentonite waterproof material, concrete varieties include bentonite water swelling seal, bentonite waterproof board and bentonite waterproof blanket and bentonite powder waterproof material.
Special waterproof materials choose to use metal waterproof membrane, research and application of cultural relic protection and other special waterproof coatings.
