Abstract

The invention relates to an environment-friendly modified-asphalt coating material and a preparation method thereof and belongs to the technical field of paint and preparation processes thereof. The coating material contains the following ingredients in parts by weight: 30-42 parts of petroleum asphalt, 25-31 parts of polyethylene oxide, 19-27 parts of glycidyl methacrylate, 4-8 parts of polyvinyl chloride paste resin, 5-20 parts of dioctyl phthalate, 15-21 parts of SBS (Styrene Butadiene Styrene block polymer) thermoplastic rubber, 15-25 parts of UPVC (Unplasticized Polyvinyl Chloride) and 5-12 parts of CPVC (Chlorinated PVC). According to the scheme, volatile organic solvents are not adopted, so that the coating material is environmentally-friendly. Meanwhile, the coating material disclosed by the invention is excellent in heat resistance, integrates chemical stability and heat resistance, can still work normally below 200 DEG C and has good stability.

Description

Technical field [0001] The invention belongs to the technical field of paint and its preparation process, and specifically relates to an environmentally-friendly modified asphalt paint and a preparation method thereof. Background technique [0002] Asphalt has good water resistance and durability. The common domestic modified bitumen is usually used in the waterproof field. Its preparation method uses petroleum bitumen as the base material, SBS rubber as the modifier, natural nano-materials as fillers and supplemented by molecular polymers. [0003] The coating is not only costly, but the indicators do not meet the requirements of environmental protection, affect human health, and cause pollution to the environment. Therefore, it is necessary to provide a new type of environmentally friendly modified asphalt coating to improve the heat resistance and stability of the coating Sex. Summary of the invention [0004] The purpose of the present invention is to overcome the abov...
