Waterproof flame-retardant sealing coating and preparation method thereof

Abstract

The invention discloses a waterproof flame-retardant sealing coating and a preparation method thereof. The waterproof flame-retardant sealing coating is prepared from the following raw materials in parts by weight: 70-90 parts of water, 50-70 parts of ethyl acrylate,15-25 parts of titanium dioxide, 20-40 parts of bentonite, 10-20 parts of calcium carbonate, 15-25 parts of talcum powder, 5-7 parts of a DA dispersing agent, 3-5 parts of a filming additive, 1-2 parts of a defoaming agent and 2-4 parts of methylparaben and propylparaben, wherein the weight part ratio of methylparaben to propylparaben is (1-3):1. The waterproof flame-retardant sealing coating disclosed by the invention is high in flame retardancy, good in corrosion resistance, unlikely to peel off and long-lasting in waterproof sealing effect. The technical effect of the waterproof flame-retardant sealing coating disclosed by the invention is possibly related to the weight part ratio of methylparaben to propylparaben in the raw materials, and the waterproof flame-retardancy property is the best when the weight part ratio of methylparaben to propylparaben is (1-3):1.

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...

AI Technical Summary

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.
