Abstract
The invention discloses a waterborne acrylic acid and asphalt anti-corrosive paint and a preparing technology thereof, and relates to the technical field of waterborne paints. The problem that a paintfilm formed after a waterproof paint is in use is easily aged, and the overall application effect of the paint is poor accordingly is solved. The waterborne acrylic acid and asphalt anti-corrosive paint is prepared from, by weight, 40-50 parts of an acrylic acid emulsion, 3-7 parts of petroleum asphalt, 2-5 parts of titanium dioxide, 0.6-1.2 parts of a Tex film-forming agent, 0.2-0.6 part of polydimethylsiloxane, 1-3 parts of sodium pyrophosphate, 3-5 parts of alumina micro powder, 2-4 parts of waste micro-rubber powder, 1.6-2.4 parts of a filler, 1.2-1.8 parts of a fiber material, 0.4-0.8 part of an emulsifier and 2-3 parts of a dispersing agent. The waterborne acrylic acid and asphalt anti-corrosive paint has good environmental protection performance, a coating formed after use has goodageing resistance, the overall quality is high, and the paint has a good application effect.
Description
technical field [0001] The invention relates to the technical field of water-based paint, more specifically, it relates to a water-based acrylic asphalt anticorrosion paint and a preparation process thereof. Background technique [0002] Asphalt is a brown or dark brown organic gelling material. It is an indispensable material in civil engineering construction and is widely used in construction, highways, bridges and other projects. Asphalt coatings are solvent-based or water-emulsion waterproof coatings based on asphalt. They are mainly used in emerging marine engineering, modern transportation, important energy industries, and large-scale industrial and mining enterprises. [0003] A Chinese invention patent application document with the publication number CN107177223A discloses a waterproof coating and a preparation method thereof. The coating includes the following components: acrylic emulsion, propylene glycol methyl ether acetate, epoxy resin, zinc oxide butyl acrylate...
