Abstract

The invention discloses an JS elastic waterproof coating consisting of the following components in percentage by weight: 20-30% of a liquid material and 70-80% of a powder material, wherein the liquid material comprises the following components in percentage by weight: 80-95% of a pure acrylic emulsion, 4.9-19% of water, 0-2% of a water reducing agent, 0.1-0.2% of a preservative and 0-1% of a defoaming agent; the powder material comprises the following components in percentage by weight: 40-65% of Portland cement, 15-30% of quartz sand, 10-30% of quartz powder and 0-0.5% of cellulose. The waterproof coating disclosed by the invention has excellent waterproof performance, good weather resistance and gas permeability, high binding strength and excellent construction process, and can be used for repairing cracks.

Description

technical field [0001] The invention relates to the field of waterproofing of civil buildings, in particular to a high-performance elastic waterproof coating for buildings, in particular to a JS elastic waterproof coating, which belongs to a polymer cement waterproof coating. Background technique [0002] Building leakage is a major problem that has plagued people for a long time. It not only disrupts normal life but also causes economic losses. Therefore, building waterproofing has become an important field that needs to be developed and researched in construction projects. As the main material of waterproofing engineering, architectural waterproof coatings are of great importance. There are two main types of waterproof coatings on the market: one is polyurethane waterproof coatings, which are made by mixing prepolymers containing isocyanate groups, curing agents containing polyhydroxyl or amine groups, and other additives in a certain proportion. form. This kind of react...
