Problems solved by technology

[0003] The application number is CN201711207161.8 patent, which discloses polyethylene polypropylene fiber composite waterproof membrane and its preparation method. The plastic sheet extruded by polyethylene resin, polytetrafluoroethylene, light calcium carbonate and other raw materials is completely composited with polypropylene fiber. The composite waterproof membrane obtained has strong water resistance, weather resistance and chemical stability, but due to the poor elasticity and ductility of the polypropylene fiber, the produced waterproof membrane has weak strain capacity of the base layer and is easy to break and be damaged.

Abstract

The invention discloses a composite waterproof coiled material and a preparation process thereof. The composite waterproof coiled material is prepared from a modified polyethylene waterproof base material and a blend fiber cloth which are composited. The modified polyethylene waterproof base material comprises the following raw materials of, by weight, 100 parts of chlorosulfonated polyethylene, 50-70 parts of high chlorinated polyethylene, 25-35 parts of fluorocarbon resin, 10-20 parts of maleic anhydride grafted ethylene-propylene-diene monomer rubber, 0.2-1 part of 3-aminopropyl trimethoxysilane, 0.8-2 parts of antioxidants and 40-60 parts of filling enhancers. The blend fiber cloth is formed by 60-70% of poly (metaphenylene isophthalamide) fibers and 30-40% of polyethylene glycol terephthalate fibers which are woven in a mixed mode. Traditional primary polyethylene is replaced with the chlorosulfonated polyethylene, a unique vulcanization structure of the chlorosulfonated polyethylene is physically crosslinked with the fluorocarbon resin and the maleic anhydride grafted ethylene-propylene-diene monomer rubber to improve the strength and thermal stability of the coiled material,meanwhile, a traditional polypropylene non-woven fabric is replaced with the blend fiber cloth, and thus the telescopic elasticity, ductility and heat resistance of the coiled material are improved.

Description

technical field [0001] The invention belongs to the field of waterproof coiled materials, and in particular relates to a composite waterproof coiled material and a preparation process thereof. Background technique [0002] Polyethylene polymer composite waterproof membrane is composed of primary polyethylene polymer material and polypropylene filament non-woven fabric. It has the advantages of strong impermeability, good low temperature flexibility, and small expansion coefficient. Stretchable elasticity, when the base layer of the building is deformed, the waterproof membrane is easily broken and damaged under the action of external tensile stress, losing the waterproof effect, and has poor high temperature resistance, fire resistance and flame retardancy. Therefore, a new type of polyethylene composite waterproof membrane with strong base adaptability, high temperature resistance and flame retardancy has broad market prospects and important application value.
