Abstract

The invention discloses a high-strength waterproof emulsion. The high-strength waterproof emulsion comprises, by weight, 60 to 64 parts of acrylamide, 16 to 16.7 parts of alkylphenol polyoxyethylene,71 to 73 parts of disodium nonylphenol polyoxyethylene ether sulfosuccinate, 2300 to 2330 parts of butyl acrylate, 990 to 1010 parts of styrene, 9 to 11 parts of sodium bicarbonate, 8.3 to 8.7 parts of sodium persulfate, 9.5 to 10.5 parts of tert-butyl hydroperoxide, 4 to 4.5 parts of rongalite powder, 10 to 50 parts of a pH conditioning agent, 3 to 9 parts of a later additive, and 2500 to 3000 parts of water. The high-strength waterproof emulsion possesses enough high tensile strength, and is capable of satisfying requirements on the strength of waterproof materials under different using conditions.

Description

technical field [0001] The invention relates to the field of waterproof coatings, more specifically, it relates to a high-strength waterproof emulsion and a preparation method thereof. Background technique [0002] Traditional waterproof materials mainly include flexible waterproof materials such as waterproof membranes, waterproof coatings, and sealing ointments, as well as rigid waterproof materials that are based on cement substrates and added with liquid medicine and other additives. Most waterproof projects in my country use traditional waterproof materials, which have disadvantages such as poor aging resistance, low tensile strength, and sensitivity to temperature. Traditional waterproof coatings are used for roof waterproofing, which is easy to cause aging, cracking, deformation, breakage, delamination, etc., and the quality is even more difficult to guarantee. People have to spend a lot of money and labor for repairs every few years, which not only disrupts people's ...
