Abstract

The invention relates to the technical field of research and development of building coatings and discloses a high-strength elastic waterproof building coating. The building coating is excellent in waterproof property, has ultra-strong infiltration capacity, excellent impervious performance and high harmful chemical erosion resistance, is capable of automatically and rapidly repairing micro-cracks, non-toxic, excellent in flexibility, safe and environmentally friendly, capable of resisting displacement of the building due to expansion or contraction, excellent in gas permeability, favorable for vapor volatilization inside the building, excellent in cohesiveness with most of base materials, convenient in construction, seamless, high in curing speed and applicable to roof, balconies, bathrooms, kitchens, swimming pools, basements, reservoirs, interior walls and the like, can greatly reduce erosion and damage effects of external moisture and corrosive media on concrete construction, and has significances for improving the durability and service life of concrete buildings.

Description

technical field [0001] The invention belongs to the technical field of research and development of architectural waterproof coatings, and in particular relates to a high-strength elastic waterproof architectural coating. Background technique [0002] Driven by downstream industries, China's coatings industry is growing day by day, and architectural coatings, one of its branches, have also achieved considerable development. Statistics show that in 2011, the total output of China's architectural coatings was about 3.5182 million tons, an increase of more than 30% year-on-year. It can be seen that although China's architectural coatings industry has experienced the impact of the global financial crisis in 2008, rising raw material prices and the pressure brought by the central bank's interest rate hike, its development momentum remains unabated and it maintains a relatively high growth rate. Paint is a material that can be well bonded to the base material and form a complete a...
