Self-adhesive glue for polymer waterproof coiled material, preparation method thereof, and polymer waterproof coiled material

Abstract

The invention relates to the field of waterproof coiled materials, and particularly discloses a self-adhesive glue for a high-molecular waterproof coiled material, a preparation method thereof, and the high-molecular waterproof coiled material. The self-adhesive glue is prepared from 10-20 parts of an acrylate emulsion, 20-30 parts of alkyd resin, 10-20 parts of hydroxystyrene, 2-4 parts of a thickening agent, 2-4 parts of a defoaming agent, 3-5 parts of a dispersing agent and 30-50 parts of water. The preparation method comprises the following steps: uniformly mixing the water, the dispersing agent and the defoaming agent, then adding the acrylate emulsion and the hydroxystyrene, uniformly mixing, then adding the acrylate emulsion and the thickening agent, and uniformly stirring to obtain the self-adhesive glue. The self-adhesive glue can be used for the bonding part of the waterproof roll and concrete, and has the advantages of high bonding strength and wet paving capability; in addition, according to the preparation method disclosed by the invention, the alkyd resin is fully reacted with the acrylate emulsion and the hydroxystyrene, so that the bonding strength of the self-adhesive glue is improved; and the waterproof coiled material prepared by the invention can adopt a construction mode of dry paving or wet paving and the like, and a concrete protection layer does not need to be arranged on the waterproof coiled material, so that green construction is realized, and energy conservation and environmental protection are realized.

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.
