Abstract

The invention provides a novel modified asphalt waterproof roll. The novel modified asphalt waterproof roll is characterized by being prepared from polyester reinforcement, prepreg, a coating material and an isolation material, wherein the prepreg is prepared from the following components of heavy duty bitumen, rubber, mineral fillers and an antiager; the coating material is prepared from the following components of heavy duty bitumen, second-line distillation oil, rubber, mineral fillers, tire rubber powder and an antiager. A preparation method of the novel modified asphalt waterproof roll comprises the steps of prepreg preparing, coating material preparing, polyester reinforcement drying, prepreg wiping, coating material coating, isolation material covering, cooling and rolling. According to the novel modified asphalt waterproof roll disclosed by the invention, the waterproof performance is good, and the tensile strength is high; the impact resistance is good; the manufacturing cost is low.

Description

technical field [0001] The invention relates to an asphalt waterproof coiled material, in particular to a novel modified asphalt waterproof coiled material and a preparation method thereof, belonging to the field of waterproof materials. Background technique [0002] The technical improvements for waterproofing mainly include catalytic oxidation asphalt and polymer modified asphalt. Modified asphalt, made of coils, called modified asphalt coils. For example, the polyethylene tire modified asphalt waterproof membrane (0EE) in Woniushan Mountain in my country belongs to oxidation modification. The other is to add rubber or resin for modification. The added material can be rubber powder, SBS rubber or others. This modification is called polymer modification. [0003] The properties and amount of the added polymer determine the performance of the modified asphalt, and the added material is called a modifier. [0004] High polymers refer to high molecular polymers, and the ran...
