Abstract

The invention discloses a wind and sand resistant solar heat reflecting coating which is prepared from the following components in percentage by mass: polyaspartic acid ester resin, pigment, padding, a dispersing agent, scratch resistant wax powder, a flatting agent, 0.2-0.5% of defoaming agent and butyl acetate. A preparation method comprises the following steps of: adding the polyaspartic acid ester resin, the dispersing agent and the defoaming agent into a paint can, stirring at the speed of 500r / min for 5-10 minutes, adding the pigment in the stirring process, and then, stirring at the speed of 800r / min for 15-20 minutes; adding 1 / 2 of butyl acetate in a formula and stirring at the speed of 500r / min for 5-10 minutes; and grinding by using a grinding machine to the fineness of 10 microns, adding the scratch resistant wax powder and the flatting agent, and then adding residual butyl acetate to adjust the viscosity. The wind and sand resistant solar heat reflecting coating not only can reflect the heat irradiated by the sun to reduce the surface temperature of a building and play the role in saving energy, but also has favorable weather resistance and wind and sand resistance so that the coating is durable and maintenance cost is low.

Description

technical field [0001] The invention belongs to the technical field of coatings, and relates to a wind-sand solar heat-reflecting coating and a preparation method thereof. Background technique [0002] In Northwest China, summer is hot, the intensity of solar heat radiation is high, and the surface temperature of objects can be as high as more than 70 degrees Celsius. In winter and spring, there is a lot of wind and sand, which has a strong wind erosion effect on the paint film. At present, the practical anti-wind and sand coatings on the market use polyurethane, which has general weather resistance and anti-wind and sand performance, and has no solar heat reflection function, so it cannot cool down and save energy. Contents of the invention [0003] The purpose of the present invention is to provide a coating that can reflect the heat of summer solar radiation so that the surface temperature of the building is much lower than that of ordinary coatings, so as to achieve th...
