Abstract

The invention provides an ultralow temperature spraying non-curing rubber asphalt waterproof paint, and aims to solve the problems caused by high temperature spraying of a conventional waterproof paint. The waterproof paint comprises asphalt, hot melt adhesive, tackifying rubber, modified filler, a polyamide epoxy curing agent, phosphatized nano silicon oxide, and dodecanol ester. The waterproof paint is modified by the polyamide epoxy curing agent, phosphatized nano silicon oxide, and dodecanol ester; the viscosity is reduced, the flowing performance is improved, the spraying can be carried out at a low temperature, and the high energy consumption and severe pollution of high temperature spraying are avoided. At the same time, the invention also discloses a preparation method of the ultralow temperature spraying non-curing rubber asphalt waterproof paint and a creep type non-curing rubber asphalt waterproof coiled material, which comprises an asphalt layer composed of the ultralow temperature spraying non-curing rubber asphalt waterproof paint.

Description

technical field [0001] The invention relates to the technical field of building waterproof materials, in particular to an ultra-low temperature sprayed non-curing rubber asphalt waterproof coating. Background technique [0002] Waterproof coatings are commonly used building materials in the construction field. Compared with polymer waterproof coatings or polyurethane waterproof coatings, the existing non-curing spray rubber asphalt waterproof coatings have better deformation resistance, self-healing properties, tensile strength, and weather resistance. advantages such as sex. Due to its temperature resistance, low fluidity and high viscosity, the spraying of non-curing spray rubber asphalt waterproof coating must be carried out at a high temperature of 180-220 ° C, but high temperature construction is accompanied by high energy consumption and a large amount of volatilization due to high temperature High pollution caused by sulfur, carbon, nitrate and other toxic gases. Th...
