Problems solved by technology

While the reactive polymer cement waterproof coating has the above-mentioned excellent properties, it also has the common problems of waterproof coatings: the waterproof layer is greatly affected by the deformation of the base layer. Once the base layer cracks and the waterproof layer is subjected to tensile stress, the waterproof layer on both sides of the crack will There is almost no peeling area, and the tensile stress cannot be transmitted to both sides and is concentrated in the cracked part. A small crack may cause the waterproof layer to be pulled apart
[0004] Existing metal roof waterproof coatings are often the same kind of waterproof coating, and the same kind of waterproof coating is coated with two to three layers on the metal roof to improve waterproof performance, but the fusion effect between the applied multi-layer coatings is not good , the outermost coating is easy to fall off after a period of time, resulting in poor waterproof performance

Abstract

The invention discloses a conjoined reaction type reactive acrylic resin waterproof coating and a coating method thereof, and belongs to the field of waterproof coatings; the conjoined reaction type reactive acrylic resin waterproof coating comprises a first reactive acrylic resin waterproof coating and a second reactive acrylic resin waterproof coating, and the two reactive acrylic resin waterproof coatings comprise the following main components: 15 to 30 parts of butyl methacrylate, 10 to 20 parts of butyl acrylate, 5 to 15 parts of 2-ethylhexyl acrylate, 1 to 3 parts of triethylene glycol diacrylate, 15 to 30 parts of aliphatic elastic polyurethane resin, 0.5-2 parts of a fumed silica anti-settling agent, and 5 to 10 parts of rutile type titanium dioxide. The reactive acrylic resin waterproof coating is divided into two types which are respectively used as an inner layer and an outer layer, and in the coating process, the two waterproof coatings react with each other and are bondedto form a 'connection reaction', so that the bonding degree between the two waterproof coating layers is greatly improved, the coating layer of the outer layer is not easy to fall off, and the waterproof performance is excellent.

Description

technical field [0001] The invention relates to the field of waterproof coatings, and more specifically relates to a conjoined reaction type reactive acrylic resin waterproof coating and a coating method thereof. Background technique [0002] Waterproof coating The waterproof film formed by the coating on the base layer after curing has certain strength, good extensibility, crack resistance, impermeability and weather resistance, and has good temperature adaptability, easy operation and easy maintenance. and maintenance. Compared with the waterproof membrane, the waterproof coating has strong adaptability to the base layer, and the waterproof layer has no seams, which is more reliable. Due to the above characteristics, waterproof coating is one of the main waterproof materials often used in waterproofing projects. [0003] Reactive polymer cement waterproof coating, as an improved variety of polymer cement waterproof coating, is a high-solid content coating that reacts and...
