Problems solved by technology
[0004] In view of the above-mentioned related technologies, the inventor believes that: each component of the above-mentioned asphalt rubber only uses adsorption to bond the waterproof membrane to the concrete base, and the bonding strength is weak. When the waterproof membrane is used for a long time , the corners of the waterproof membrane are easily bonded to the concrete, resulting in warping and other phenomena

Abstract
The present application relates to the field of waterproof membranes, and specifically discloses a self-adhesive adhesive for polymer waterproof membranes, a preparation method thereof, and polymer waterproof membranes. The self-adhesive includes 10~20 parts of acrylate emulsion, 20~30 parts of alkyd resin, 10~20 parts of hydroxystyrene, 2~4 parts of thickener, 2~4 parts of defoamer, 3~5 parts of dispersant 30~50 parts of water; the preparation method is: first mix water, dispersant and defoamer, then add acrylate emulsion and hydroxystyrene, after mixing, add acrylate emulsion and thickener, stir well , to obtain the self-adhesive. The application can be used for the joint between waterproofing membrane and concrete, and it has the advantages of high bonding strength and wet laying; in addition, the preparation method of the application makes alkyd resin fully react with acrylate emulsion and hydroxystyrene, increasing The bonding strength of the self-adhesive is guaranteed; the waterproof membrane prepared by the application can be constructed by dry laying or wet laying, and the concrete protective layer is not required on the waterproof membrane, which is green construction, energy saving and environmental protection.
Description
technical field [0001] The present application relates to the field of waterproof rolls, more specifically, it relates to a self-adhesive for polymer waterproof rolls, a preparation method thereof, and a polymer waterproof roll. Background technique [0002] Waterproof membrane is a flexible building material product that can be rolled into rolls, which can resist rainwater or groundwater leakage, and has good pressure sensitivity, self-healing and waterproof properties; waterproof membrane is easy to construct and has been widely used in construction Walls, roofs, tunnels, roads and other occasions; polymer waterproof membranes are mainly composed of waterproof membranes and adhesives. The waterproof membranes play a major role in waterproofing, and the adhesive is used to bond the waterproof membranes to concrete surface. [0003] The Chinese invention patent with the application publication number CN107446366A discloses a kind of bituminous rubber compound for waterproof...
