Abstract

The invention relates to a self-healing polymer cement waterproofing coating. The self-healing polymer cement waterproofing coating comprises a liquid material component A and a powder material component B in a weight ratio of 1:(1.0-1.2), wherein the liquid material component A comprises the following components in percentage by weight: 15 to 50 percent of ethylene-vinyl acetate copolymer emulsion, 35 to 65 percent of crylic acid emulsion, 0.2 to 0.8 percent of acrylic resin, and 14.20 to 19.80 percent of water. The powder material component B comprises the following components in percentage by weight: 19.50 to 37.50 percent of low alkali rapid hardening sulphate aluminium cement, 62.10 to 80.35 percent of quartz sand, 0.05 to 0.15 percent of hydroxypropyl methyl cellulose, 0.05 to 0.10 percent of water reducing agent, and 0.05 to 0.15 percent of antifoaming agent. The waterproofing coating is bonded firmly, has high tensile strength, a good permeability resistance effect, is not easy to crack and has the function of repairing fine cracks.

Description

technical field [0001] The invention relates to waterproof materials, in particular to a self-healing polymer cement waterproof coating and a preparation process thereof. Background technique [0002] With the strengthening of environmental awareness, water-based environmentally friendly polymer cement waterproof coatings are widely used in the field of building waterproofing. At present, there are mainly three types of polymer cement waterproof coatings on the market, and their elongation at break varies from elongation at break ≥ 200% to elongation at break ≥ 30%. These polymer cement waterproof coatings are applied to actual projects. If there is no cracking, the waterproof effect is very good, but in practice, due to various reasons, there may be some small cracks in the coating film of polymer cement waterproof coatings, and its waterproof effect will be greatly improved. Discount. Contents of the invention [0003] In order to solve the deficiencies in the prior ar...
