Abstract

The invention discloses a rubber powder modified emulsified asphalt waterproof coating. The rubber powder modified emulsified asphalt waterproof coating comprises emulsified asphalt and a rubber powder emulsion. Asphalt is prepared into the emulsified asphalt, swelling treatment is performed on rubber powder, the swollen rubber powder is prepared into the rubber powder emulsion, the emulsified asphalt and the rubber powder emulsion are metered, mixed and uniformly stirred, and high-speed shear modification treatment is performed by a colloidal mill to obtain the rubber powder modified emulsified asphalt waterproof coating disclosed by the invention. The waterproof coating keeps the excellent performances of rubber modified asphalt, solves the problem that the rubber modified asphalt can not be saved and used at normal temperature, overcomes the shortcomings of high energy consumption, inconvenience in construction, environmental pollution and the like of the rubber modified asphalt, and overcomes the problems of expensive price, complex manufacturing process and the like of traditional SBS (styrene-butadiene-styrene) and SBR (styrene butadiene rubber) modified emulsified asphalt. The rubber powder modified emulsified asphalt waterproof coating disclosed by the invention takes waste tire rubber powder as a modifying material so as to be in line with the national industrial policy of circular economy and low-carbon economy.

Description

technical field [0001] The invention relates to a waterproof material, in particular to a rubber powder modified emulsified asphalt waterproof coating and a preparation method thereof Background technique [0002] Rubber modified asphalt is widely used in the construction field due to its good waterproof performance and weather resistance. The modification of rubber powder to asphalt is based on their full mixing. Under high temperature conditions, the asphalt softens and the rubber powder particles absorb the asphalt. After the light part, swelling occurs. Through high-speed shearing, the swollen rubber particles interact with the rest of the asphalt to form a new structural system. The inherent characteristics of rubber can improve the performance of asphalt accordingly. However, during the production and use of rubber asphalt, it needs to be carried out under high temperature conditions, which will cause problems such as high energy consumption, inconvenient construction,...
