Problems solved by technology

[0005] On the other hand, water-based acrylate waterproof coatings have been widely used in construction, and there are mainly two forms: polymer emulsion architectural waterproof coatings and polymer cement waterproof coatings; these two coatings depend on the slow volatilization of water. The accumulation and accumulation of each component forms a film, and the solidification time is long. At present, the construction method of roller coating and scraping coating is still used
At present, there is no quick-setting water-based acrylic architectural waterproof coating suitable for spraying construction in China.

Abstract

The invention discloses a quick-setting polymer latex waterproof coating. The waterproof coating comprises a main agent component A and a curing agent component B in a weight ratio of 1:(0.5-1), wherein the main agent component A comprises the following components: polymer latex, an inorganic filler, a stabilizing agent, a plasticizing agent, a dispersing agent, an organic silicon defoaming agent and a preservative; the polymer latex is acrylate latex; the curing agent component B comprises silicate solution and water; the silicate solution is sodium silicate solution or potassium silicate solution; and the degree Baume of the silicate solution is 40-50Be and the modulus is 2.0-3.5. The invention develops the waterproof building coating suitable for spraying construction. Tests prove that the waterproof building coating can be solidified in 3-6 seconds after trace components of the coating are sprayed and contacted, and is free from flowing and dripping.

Description

technical field [0001] The invention relates to a building waterproof paint, in particular to a quick-setting polymer emulsion waterproof paint, which belongs to the technical field of building materials. Background technique [0002] Architectural waterproof coating is a viscous liquid polymer synthetic material with no fixed shape at room temperature. After coating, it can form a tough waterproof coating film on the surface of the base layer after the volatilization of solvent or water evaporation or reaction curing. the general term for. Common types of waterproof coatings include polyurethane waterproof coatings, one-component polyurethane waterproof coatings, polymer cement waterproof coatings, polymer emulsion waterproof coatings, asphalt waterproof coatings and modified bitumen waterproof coatings. [0003] After more than half a century of development, the performance of architectural waterproof coatings has been comprehensively improved, and the environment has gra...
