Spray setting of rubber asphalt waterproof coating technology
Abstract:In this article, through emulsion of each component in the ratio, concentration of emulsion breaker (calcium chloride solution) and the ratio of emulsion and demulsifier research suitable spray coating; Through the miniaturization of spraying equipment design and assembly, and ultimately determine the optimal spraying conditions.Research shows that the rubber latex in the tar from 50% to 40%, the performance optimization; Chloroprene rubber latex and styrene butadiene rubber latex mixed with the same quality than and asphalt emulsion, the neoprene latex impact on performance than butyl benzene latex; Demulsifier concentration at 20% after falling for the apparent appropriate optimization. This study realized the spraying quick-setting rubber asphalt waterproof paint spraying equipment miniaturization, and miniaturization of testing sample preparation for laboratory research bring convenience.
Keywords: Latex formula; demulsifies; Miniaturization of spraying equipment; performance
