Problems solved by technology

In recent years, more and more attention has been paid to the polymerization of silicone emulsions. Silicone emulsions have the advantages of good hydrophobicity, strong adsorption to substrates, and strong penetration. Good, poor permeability when external coating, high alkalinity, complex synthesis process, long curing time, poor storage stability, poor repair effect for wider cracks, poor water resistance, poor weather resistance, low cost performance, therefore, a new Silicone Water Repellent

Abstract

The invention relates to a waterproof material, concretely relates to an organosilicon waterproof agent, and belongs to the technical field of coatings. The organosilicon waterproof agent is prepared from, by weight, 55-60% of sodium methyl alcoholate silicate, 10-14% of methyl methacrylate, 3-4% of an emulsifier (octylphenol polyoxyethylene ether: sodium dodecyl benzene sulfonate of 2:1), 0.4-0.6% of potassium persulfate, and the balance of deionized water. The organosilicon waterproof agent has the advantages of firm combination to silicate in concrete, difficult erosion ageing, strong hydrophobicity, good permeability, low engineering cost, reduction of the construction difficulty and intensity of workers, reduction of engineering accidents, reduction of pollution to environment, and obvious advantages.

Description

technical field [0001] The invention relates to a waterproof coating, in particular to a silicone waterproofing agent, which belongs to the technical field of coatings. Background technique [0002] Waterproofing is an important measure to improve the durability of cement concrete structures. In recent years, more and more attention has been paid to the polymerization of silicone emulsions. Silicone emulsions have the advantages of good hydrophobicity, strong adsorption to substrates, and strong penetration. Good, poor permeability when external coating, high alkalinity, complex synthesis process, long curing time, poor storage stability, poor repair effect for wider cracks, poor water resistance, poor weather resistance, low cost performance, therefore, a new Silicone water repellent. Contents of the invention [0003] The invention can bond more firmly with the silicate in concrete, is not easy to be corroded and aged, has strong hydrophobicity, good air permeability, ...
