Abstract

The invention provides a odorless ethylene propylene diene monomer (EPDM) rubber waterproof coating and a preparation method thereof. The coating comprises the following dry materials by the total mass parts of the coating: 80-120 parts of EPDM rubbers, 25-35 parts of SBR, 50-70 parts of SBS, 50-70 parts of terpene resins, 3-7 parts of nanometer zinc oxide, 45-65 parts of nanometer calcium carbonate, 4-10 parts of nanometer titanium dioxide, 155-215 parts of odorless solvent and 200-300 parts of non-toluene solvent. Three kinds of nanoparticles are added to the coating, and through scientific proportioning, the fillers can be uniformly dispersed in the solvents with the rubbers, thus solving the precipitation problem of the coating and greatly improving intermixing. The content of solid in the coating is improved from 40% to 48%, thus the coating is easy to be thicker during construction. The waterproof coating also has the functions of ozone decomposing, sterilizing and self-cleaning. After the odorless solvent is added, the product has the characteristic of odorlessness and is more environment-friendly, and the quality of the product is further ensured.

Description

technical field [0001] The invention relates to a building waterproof coating, in particular to a waterproof coating added with nanometer materials and a preparation method thereof. Background technique [0002] Waterproof coating is a new material widely used in industrial and civil buildings after asphalt waterproofing and mortar waterproofing. In solvent-based waterproof coatings with synthetic rubber as the main film-forming material, the tensile strength and crack resistance of the coating film are important factors affecting the performance of the coating. The existing EPDM waterproof coating has a relatively single formula, and the coating's own performance, bactericidal performance, and environmental protection performance all need to be improved. [0003] Although the existing acrylic waterproof coatings added with nanoparticles aim to improve the performance of the coating and enhance its bactericidal effect, the calcium carbonate and talcum powder added in a larg...
