Problems solved by technology

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. When used for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It takes a lot of money and labor to repair every few years, which not only disrupts people's normal life, work and production order, but also affects the service life of the entire asphalt building.

Abstract

The invention discloses an asphalt waterproofing coating, comprising the following raw materials in parts by weight: 63-70 parts of silicone acrylic emulsion, 3-5 parts of asphalt, 2-3 parts of beewax, 0.5-1 part of sodium aluminate, 1-2 parts of orthocide, 0.2-0.3 part of hexafluoroacetylacetone, 0.7-2 parts of disodium octaborate tetrahydrate, 5-7 parts of fluorapatite, 4-5 parts of poly(butyl acrylate), 0.5-1 part of antioxidant 1010, 2-3 parts of konjac glucomannan, 0.4-1 part of 2-octyl-3(2H)-isothiazolone, 6-10 parts of fluorite powder, 3-5 parts of calcium sulfate dihydrate powder, 0.2-0.4 part of N-hydroxymethyl acrylamide, 6-7 parts of coalescing agent and 10-15 parts of deionized water. The bonding strength of the coating can be effectively improved by the asphalt, the beewax, the konjac glucomannan and the like added to the waterproofing coating disclosed by the invention, the bonding effect with a base material is enhanced, the stability and the peel strength of a film are improved, and the film is good in water resistance, good in acid and alkali resistance and strong in ageing resistance.

Description

technical field [0001] The invention mainly relates to a coating, in particular to an asphalt waterproof coating. 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. When used for indoor waterproofing, it is difficult to construct for places with complex shapes, and it is even more difficult to guarantee the quality of leakage. It will cost a lot of money and labor to repair every few yea...
