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 dense anti-leakage building.

Abstract

The invention discloses a waterproof flame-retardant sealing coating and a preparation method thereof. The sealing coating is prepared from the following raw materials in parts by weight: 70 to 90 parts of water, 50 to 70 parts of ethyl acrylate, 15 to 25 parts of titanium dioxide, 20 to 40 parts of bentonite, 10 to 20 parts of calcium carbonate, 15 to 25 parts of talcum powder, 5 to 7 parts of a DA type dispersing agent, 3 to 5 parts of a coalescing agent, 1 to 2 parts of an antifoaming agent and 2 to 4 parts of methyl acrylate and butyl acrylate together, wherein the mass ratio of methyl acrylate to butyl acrylate is (1 to 3): 1. The sealing coating provided by the invention is high in flame-retardant property and high in corrosion resistance, is unlikely to fall off, and can generate a long-lasting waterproof sealing effect. The technical effects of the coating disclosed by the invention are possibly related to the mass ratio of methyl acrylate to butyl acrylate in the raw materials, and when the mass ratio of methyl acrylate to butyl acrylate is (1 to 3): 1, the waterproof flame-retardant sealing performance is the best.

Description

technical field [0001] The invention relates to a novel coating, in particular to a waterproof and flame-retardant sealing coating and a preparation method thereof. Background technique [0002] Waterproof technology is a specialized technology to ensure project quality and avoid water erosion hazards, and it occupies an important position in project construction. In daily life, ground leakage in houses, leakage and humidity in hotel toilets, leakage and humidity in underground projects are common problems. Water is a polar substance with a surface tension of about 72mN / m. It has strong diffusivity and can wet a variety of substances. It can not only flow through large void channels under gravity, but also flow in all directions through capillary pores. Therefore, an effective way to solve engineering leakage and moisture problems is to develop and apply waterproof materials. [0003] Traditional waterproof materials mainly include flexible waterproof materials such as wat...
