Abstract

The invention discloses a roofing waterproof coating with high long-term water resistance and weathering resistance. The coating comprises 300-500 parts of a mixed emulsion, 300-500 parts of a filler,50-200 parts of water, 5-10 parts of 2-(3, 4-epoxy cyclohexyl)ethyltrimethoxysilane, 1-3 parts of ammonium metavanadate, 5-10 parts of potassium hydrogen sulfate, 5-8 parts of 1, 2-propylene glycol polyadipate, 2-5 parts of triethanolamine, 1-3 parts of tetrabutylammonium bromide, 0.2-3 parts of an ultraviolet photoinitiator, a coalescing agent, a dispersant, a preservative, a defoamer and a thickener. The ERC roofing waterproof coating is an elastic seamless water-based eco-friendly waterproof coating system for the roofing, can be bonded to different roofing bases and has a sunlight or heatreflecting function and high performances. Compared with the existing waterproof coating, the ERC roofing waterproof coating further improves long-term water resistance and weathering resistance, bonding performances and heat resistance, does not contain an organic solvent and formaldehyde and is an eco-friendly roofing waterproof coating.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a roof waterproof paint with improved long-term water resistance and weather resistance. Background technique [0002] The roof is the uppermost outer protection component of the building, which is used to resist the influence of unfavorable factors such as rain, snow, wind, frost, solar radiation and temperature changes in nature, and to ensure a good use environment inside the building. The roof should meet the requirements of strong Functional requirements for durability, waterproofing, thermal insulation, heat insulation, fire protection and resistance to various other adverse effects. [0003] Due to the harsh environment where the roof is exposed to wind, sun, and rain for a long time, it is easy to cause the aging of the roof material and water seepage and leakage. At present, the price of polyurethane waterproof coatings used in my country's roof wa...
