Abstract

The invention discloses a chlorinated polyethylene waterproof coiled material and its preparation method. The material adopts chlorinated polyethylene as the base material, and thermoplastic polyolefin, a filling agent and other auxiliaries are also added. An extrusion calendaring molding method is employed to prepare the chlorinated polyethylene waterproof coiled material, which has multiple excellent comprehensive economic and technical performance indicators of excellent waterproofness, leakage resistance and weatherability, high tensile strength, high elongation, aging resistance, strong deformation adaptability, wide temperature adaptation range, high binding strength, long service life, easy construction and low cost, etc., thus being able to be used in bridge floor concrete of passenger dedicated lines, subways, roads, ports and wharfs, large underground projects, and other waterproof projects.

Description

technical field [0001] The invention belongs to the field of waterproof material preparation, and in particular relates to a chlorinated polyethylene waterproof coiled material and a preparation method thereof. Background technique [0002] Chlorinated polyethylene is a polymer material obtained by chlorination substitution reaction of high-density polyethylene. According to its chlorine content, residual crystallinity and other technical characteristics, it can be divided into resin-type chlorinated polyethylene and rubber-type chlorinated polyethylene. Ethylene (referred to as CM). Since chlorinated polyethylene is a chlorine-containing high polymer, it is soluble in aromatic hydrocarbons and halogenated hydrocarbons, but insoluble in aliphatic hydrocarbons. It decomposes and releases hydrogen chloride gas above 170°C, and it is still soft at -30°C. Rubber-type chlorinated polyethylene is a new type of synthetic material made of HDPE through random chlorination. Its mole...
