Abstract

The invention discloses a polyvinyl chloride modified asphalt waterproof roll and a preparation method thereof. According to the polyvinyl chloride modified asphalt waterproof roll, petroleum asphalt is used as a base material and an extrusion and calendaring formation method is carried out in the presence of polyvinyl chloride, filler and aids to obtain the polyvinyl chloride modified asphalt waterproof roll. The polyvinyl chloride modified asphalt waterproof roll has various excellent comprehensive economical and technical performance indexes such as excellent weatherability, high tensile strength, high elongation, ageing resistance, strong deformation adaptability, wide temperature adaptation range, high bond strength, long service life, non pollution, easiness in construction and low cost and can be used in waterproof engineering of passenger special line deck concrete, metros, roads, port terminals and underground large projects.

Description

technical field [0001] The invention belongs to the field of waterproof material preparation, and in particular relates to a polyvinyl chloride modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Polyvinyl chloride is a polymer polymerized from vinyl chloride monomer. It is a transparent or opaque waxy substance similar to PE with a density of 2.2g / cm 3 , The water absorption rate is less than 0.01%. With its excellent high and low temperature resistance and chemical stability, good electrical insulation performance, non-adhesion, weather resistance, flame retardancy and good self-lubrication, it has the reputation of "King of Plastics" and has been widely used in chemical industry, Petroleum, textile, electrical and electronic, medical, machinery and other fields have been widely used. [0003] With the rapid development of highway construction in our country, a large number of high-grade highways are paved and the c...
