Abstract

The invention belongs to the technical field of building materials, and proposes a novel modified asphalt waterproof coiled material, which includes a modified asphalt coating layer, a base layer and an isolation layer. The material of the modified asphalt coating layer is modified asphalt, modified asphalt It consists of the following components by weight: 5-10 parts of 10# asphalt, 40-50 parts of 90# or 100# asphalt, 6-12 parts of softening oil, 4-6 parts of rubber powder, 3-5 parts of SBS, high density 2 to 4 parts of polyethylene, 0.2 to 0.6 parts of triallyl isocyanurate, 0.6 to 2 parts of dicumyl peroxide, and 10 to 20 parts of filler. Grinding and preparing modified asphalt, and then coating the modified asphalt on the upper and lower surfaces of the base layer to obtain a base layer coated with modified asphalt coating layers on both sides, and then coating an isolation film to obtain an isolation layer, cooling and forming, and obtaining A new type of modified bitumen waterproof membrane. The invention solves the problem of defects in the high and low temperature resistance of elastomer modified asphalt and plastic body modified asphalt waterproof coiled materials in the prior art.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a novel modified asphalt waterproof coiled material and a preparation method thereof. Background technique [0002] Waterproof membrane is a kind of building material commonly used in building construction. In the construction of roads, bridges, roofs, basements and other buildings that need waterproofing, waterproof membranes need to be pre-paved. According to its main waterproof composition, it can be divided into: asphalt Waterproof membrane, polymer waterproof membrane, synthetic polymer waterproof and coating waterproof four categories. Among them, modified asphalt waterproofing membrane is the most commonly used waterproofing membrane, accounting for nearly 70% of the total market. At present, domestic modified asphalt waterproofing membranes are divided into two types: one is elastomer modified asphalt waterproofing membranes; the other is plastic modified asphal...
