Abstract

The invention relates to a super-weather resistance, high-stain resistance, composite elastic building coating, mainly comprising acrylate silicon elastic emulsion 45-55wt%, rutile TiO2 15-20wt%, nano CaCO3 2-3wt% and water the rest, where the silicon-acrylate elastic emulsion mainly comprises methyl methacrylate 11-13wt%, butyl acrylate 32-37wt%, acrylate 1.5-3wt%, organic silicon monomers 6-8wt%, emulsifier 5-3wt%, initiating agent 0.2-0.7wt%, PH regulator 0.1-0.15wt% and water the rest. And it has beneficial effects of: selecting nano CaCO3 and rutile TiO2 to modified-prepare silicon-acrylate elastic building coating, cooperatively improving synthetic performances of the coating and implementing optimum balance of elasticity, resistance, rigidity and stain-resistance.

Description

technical field

[0001] The invention relates to the field of building materials, and mainly relates to a super-weather-resistant and high-fouling-resistant composite elastic architectural paint. Background technique

[0002] With the rapid growth of the national economy, the continuous improvement of people's living standards and the emergence of a large number of high-rise buildings, higher requirements have been put forward for the decorative effect and function of architectural coatings. High-performance functional architectural coatings have become the current research and development. focus.

[0003] During many years of engineering site construction and management services, it has been found that during the long-term use of buildings, they are eroded by rain, carbon dioxide, sulfur dioxide gas, and thermal expansion and contraction caused by temperature differences, which often lead to cracks on the walls of buildings. It makes ordinary finishi...
