Abstract

The invention discloses a thermoplastic polyolefin waterproof sheet material and a preparation method thereof. The thermoplastic polyolefin waterproof sheet material comprises thermoplastic polyolefin as a base material, chlorinated polyethylene, a filler and other assistants and is prepared by an extrusion calendering molding method. The thermoplastic polyolefin waterproof sheet material has excellent comprehensive economic and technical indexes such as excellent water resistance, seepage resistance, weatherability, high tensile strength, high elongation percentage, aging resistance, strong deformation adaptability, wide temperature use range, high bonding strength, long service life, construction easiness and low cost. The thermoplastic polyolefin waterproof sheet material is used for waterproof engineering of passenger transport private line bridge floor concrete, subway, road, port terminal and underground large-scale engineering.

Description

[0001] technical field [0002] The invention belongs to the field of waterproof material preparation, and in particular relates to a thermoplastic polyolefin waterproof sheet and a preparation method thereof. Background technique [0003] Thermoplastic polyolefin (POE) is a high-performance polyolefin product that becomes rubber-elastic at room temperature. It has the characteristics of low density, large bending, high impact resistance at low temperature, and easy processing. [0004] 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 ins...
