Problems solved by technology

However, due to the impact of the global financial crisis in recent years, prices have risen, especially the prices of petroleum products and raw materials have continued to soar, and the price of asphalt, the main raw material for the production of asphalt waterproof membranes, has also continued to rise, resulting in the production of asphalt waterproof membranes. The increase in cost increases the difficulty of market promotion and engineering application

Abstract

The present invention relates to a modified bitumen waterproof coiled material and a production method thereof. The waterproof coiled material is composed of the following raw materials in parts by weight: 9.0-17.0 parts of softener, 35.0-50.0 parts of bitumen, 12.0-16.0 parts of rubber powder, 10.0-28.0 parts of modifier and 10.0-18.0 parts of filler. The production method comprises the following steps of: proportioning the raw materials, dewatering bitumen, softening machine oil, modifying resins, dispersing the filler, coating oil, cooling and cutting, sampling and checking as well as packaging and warehousing. According to the invention, using coumarone indene resins to substitute for part of 10# bitumen can improve the high-temperature resistance and low-temperature flexibility of the obtained modified bitumen coiled material and lower the material cost of the product.

Description

technical field [0001] The invention relates to a building waterproof material, in particular to a low-cost modified asphalt waterproof coiled material suitable for roofs or basements. Background technique [0002] At present, there are three major series of waterproof coiled material products currently used in the market in our country, namely: 1. Polymer plastic waterproof sheet. Such as: PVC, CPE, EVA, TPO, etc.; 2. Rubber waterproof membranes, such as: EPDM, butyl rubber, recycled rubber and chlorinated polyethylene-rubber blended waterproof membranes, etc.; 3. Asphalt or Modified asphalt waterproofing membrane, such as: SBS elastomer modified asphalt waterproofing membrane, APP plastic body modified asphalt waterproofing membrane, rubber asphalt waterproofing membrane, etc. [0003] Through many years of actual application engineering statistics, the asphalt waterproof coiled material ranks first, and it is the most common waterproof material used in buildings in my co...
