Problems solved by technology

[0003] 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
Therefore above-mentioned non-curing spraying rubber asphalt waterproof coating is restricted in the engineering of roofing and underground waterproofing

Abstract

The invention relates to a cold-construction non-curable rubber modified asphalt coating for waterproofing and a preparation method thereof, and belongs to the technical field of chemical engineering.The coating composition is prepared from the following raw materials in parts by mass: 20-40 parts of asphalt, 10-15 parts of thermoplastic rubber, 15-30 parts of a solvent, 8-12 parts of softening oil, 1-2.5 parts of a viscosity regulator, 8-10 parts of phosphated nano silicon oxide, 3-6 parts of 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, 15-30 parts of calcium carbonate powder and 1-3 parts of mineral fibers. According to the invention, the softening oil, the phosphated nano silicon oxide and the 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate are added into the waterproof coating tomodify the waterproof coating, so that viscosity of the coating is reduced, the flowing property of the coating is improved, the coating can be sprayed under a relatively low-temperature condition of60 DEG C or below, and high energy consumption and high pollution caused by high-temperature spraying are avoided. The coating can be widely applied to waterproofing, dampproofing and seepage proofingof important projects such as high-speed rails, subways, high ways, airports, underground pipe galleries, bridges, tunnels and the like.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a cold applied non-curing rubber asphalt waterproof coating and a preparation method thereof. Background technique [0002] Non-curable Rubber Modified Asphalt Coating for Waterproofing (Non-curable Rubber Modified Asphalt Coating for Waterproofing) is a new type of waterproof material with rubber powder, asphalt and special additives as the main raw materials. The state of the body, the creep is better. Due to its state in engineering application, it has the characteristics of "permeable", does not cure, can be used in various difficult construction conditions, and can adapt to lower temperatures. Due to its "pervasive" characteristics, the sealing effect is better, which solves the problem of water channeling. [0003] Due to its temperature resistance, low fluidity and high viscosity, the spraying of non-curing spray rubber asphalt waterproof coating must be carried o...
