Abstract

The invention discloses a fluorocarbon modified styrene-acrylic coating. The fluorocarbon modified styrene-acrylic coating consists of the following components in percentage by mass: 34 to 42.5 percent of GHT-1 styrene-acrylic emulsion, 5.2 to 6.5 percent of GHSF-25 fluorocarbon emulsion, 0.4 to 0.5 percent of gamma-aminopropyltriethoxysilan, 0.4 to 0.5 percent of polyethylene glycol phenyl ether, 18 to 22 percent of rutile type titanium dioxide, 8 to 10 percent of talcpowder, 8 to 10 percent of mica powder, 8 to 11 percent of calcite in powder, 0.1 to 0.15 percent of hydroxy silicone oil modified polyacrylate, 0.01 to 0.02 percent of polyether modified polysiloxane, 0.01 to 0.02 percent of kazon and the balance of water. A preparation method comprises the following steps of: modifying the styrene-acrylic emulsion by using the fluorocarbon emulsion, the gamma-aminopropyltriethoxysilan, and the polyethylene glycol phenyl ether at the temperature of between 76 and 80 DEG C, and preparing by using the modified fluorocarbon modified styrene-acrylic emulsion to obtain the fluorocarbon modified styrene-acrylic coating. The preparation process is simple, and low in investment and cost; and a product has the advantages of high weather fastness, chemical resistance, and water resistance, scrubbing resistance, and artificial aging resistance.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and relates to a coating, in particular to a fluorocarbon-modified styrene-acrylic coating and a preparation method thereof, which are mainly used in the field of architectural exterior wall coatings. Background technique [0002] In recent years, the research on styrene-acrylic coatings has achieved certain results, but there are still many problems to be solved. For example, styrene-acrylic building exterior wall coatings still have disadvantages such as high weather resistance, high chemical corrosion resistance, water resistance, scrub resistance and relatively poor artificial aging resistance. Using fluorocarbon emulsion modified styrene-acrylic emulsion to develop fluorocarbon-modified styrene-acrylic coating can overcome the existing shortcomings and meet the technical performance index requirements. Because fluorine-containing coatings have the advantages of high weather r...
