Abstract

Provided are a high-performance self-adhesion asphalt polymeric membrane composite rolled waterproof material and a preparation method thereof. The composite rolled waterproof material comprises, by weight parts, 100-150 parts of asphalt, 15-40 parts of softener, 10-20 parts of polymer modifier, 8-16 parts of tackifier and 20-30 parts of talcum powder. The invention further discloses a method for preparing the high-performance self-adhesion asphalt polymeric membrane composite rolled waterproof material. The product is stable in structure, good in flatness and stability after construction, high in tensile strength, ductility and basic layer shrinkage distortion and cracking adaptability, good in initial adhesiveness and lasting adhesion, firm in lap joint and reliable in waterproof performance, excellent in high-and-low temperature resistance, good in weather resistance, low in cost, convenient to construct and low in energy consumption and conforms to the construction energy-saving trend.

Description

technical field [0001] The invention relates to a composite waterproof coiled material and a preparation method thereof, in particular to a high-performance self-adhesive asphalt polymer film composite waterproof coiled material and a preparation method thereof. Background technique [0002] In recent years, self-adhesive membranes have become more and more widely used in domestic building waterproofing due to their convenient construction, safety and environmental protection. As a kind of self-adhesive membrane, the tireless self-adhesive membrane has more prominent advantages of convenience and energy saving. It is mainly used as a waterproof cushion, which plays the roles of waterproof, steam insulation and anti-skid. Its main structure is self-adhesive asphalt + reinforced film + isolation film. The reinforced film and isolation film used in China are mainly divided into two kinds of polymer films, HDPE film (high density polyethylene film) and PET film (polyester film)....
