Polymer modified bitumen membrane: Consolidation of SBS, APP modified bitumen membrane and self-adhesive rubber bitumen membrane, development of wet-laid self-adhesive modified bitumen membrane, promotion of roof greening practices and applications The root-resisting coiled material is actively applied to the glass-fiber tire asphalt shingles, and the use of composite-bitumen-asphalt waterproofing membranes and paper-felt linoleum is prohibited, and the use of coal tar sand-surface waterproofing membranes is prohibited.
Synthetic polymer waterproofing membrane: consolidate the application of polyvinyl chloride and EPDM waterproofing membrane, promote the formation of a polyethylene polypropylene (polypropylene) waterproof membrane and polymer cement bonding system, and accelerate the research and development of wet-laid self-adhesive Synthetic polymer waterproofing membranes, 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, promote cement-based penetrating crystalline waterproof material and silicone waterproof coating, develop and apply sprayed polyurea polyurethane waterproof coating, research and application of high solid content aqueous asphalt Base 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.
Sealing materials: consolidate the use of acrylate sealing materials (mid-range), and strongly promote the use of high-grade sealing materials such as polysulfide, silicone, and polyurethane, and actively research and apply special primers for sealing materials to improve the sealing material's adhesion, water resistance, and durability. Sex. It is forbidden to use plastic grease, PVC cement and other sealing materials.
Water Repellent: Consolidate the application of general-purpose water repellent, advocate M1500 water-based penetration waterproof agent and DPS, and promote the application of silicone water repellent and fatty acid water repellent. Restrict the use of water repellents with high chloride ion content and prohibit the use of powdered water repellents with excessive alkali content.
Grouting material: cement-based grouting material for ground reinforcement, cement-based and epoxy grouting material for structural reinforcement, especially low-viscosity moisture-cured epoxy grouting material, waterproof plugging using ultra-early self-leveling grouting cement and polyurethane, acrylate Grouting material. A composite grouting process is recommended for different engineering conditions. It is forbidden to use toxic and contaminated grouting materials such as propionic acid.
Waterproof Mortar: Actively apply polymer cement waterproof mortar, promote polypropylene fiber (PP) and nylon fiber and wood fiber anti-crack waterproof mortar, research and application of zeolite siliceous waterproofing agent. Vigorously promote the use of commercial mortar (waterproofing, heat preservation, antisepsis, cementation, filling and self-distribution of special mortar).
Waterproof and heat insulation material: consolidate the application of extrusion type, molding type polystyrene board and mortar exterior insulation system, actively promote the application of spray polyurethane rigid foam waterproof insulation material, the appropriate development and 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: active application of natural waterproof material - sodium bentonite waterproof material, specific varieties of bentonite water swelling seal, bentonite waterproof board and bentonite waterproof blanket and bentonite powder waterproof material.
Special waterproof material: choose to apply waterproof metal membrane, research and application of cultural relic protection and other special waterproof coating.
The above is the analysis of the 10 most promising waterproof materials in China and I believe there will be good prospects for development in 2010.
