Problems solved by technology

In waterproof coatings, although some waterproof coatings such as polyurethane can reach minus 40 degrees without breaking, the applicability of waterproof coatings is greatly limited due to the solvent contained in the waterproof coatings. At the same time, the addition of solvents will pollute the environment and harm the environment. The health of construction workers
In addition, the tensile strength of waterproof coatings that can reach minus 40 degrees without breaking is very low. In the application of large-scale construction projects such as high-speed rail subways, they often fail to meet the needs of actual projects.
[0004] In order to improve the poor low temperature resistance and low strength of water-based waterproof coatings, it is necessary to treat the waterproof coatings and increase the strength of the waterproof coatings to meet the needs of actual projects

Description

technical field [0001] The invention relates to the field of material technology, in particular to an ultra-low temperature resistant and high-strength rubber asphalt waterproof material, and a method for preparing and constructing an ultra-low temperature resistant and high-strength rubber asphalt waterproof material. Background technique [0002] In waterproof construction projects, in order to prevent water seepage on the surface of the substrate, the surface of the substrate will be covered with waterproof materials. In cold areas with low temperature, the temperature is often forty or fifty degrees below zero, which requires waterproof materials to have better low temperature resistance, and at the same time requires waterproof materials to have higher strength at low temperatures. [0003] Existing waterproof materials mainly include waterproof rolls and waterproof coatings. Among the waterproof membranes, polyvinyl chloride materials and thermoplastic polyolefin mate...
