Description

technical field [0001] The invention relates to the technical field of door and window coatings, in particular to a wear-resistant coating for aluminum alloy doors and windows and a preparation method thereof. Background technique [0002] Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fans. They are called aluminum alloy doors and windows, or aluminum doors and windows for short. Aluminum alloy doors and windows include doors and windows made of aluminum alloy as a force-bearing member (a member that bears and transmits its own weight and load) and wood, plastic composite doors and windows, referred to as aluminum-wood composite doors and windows, aluminum-plastic composite doors and windows. [0003] Aluminum alloys have high mechanical strength but low corrosion resistance. Although pure aluminum has good corrosion resistance, its mechanical strength is poor, which restricts the application of a...

[0003] Aluminum alloy has high mechanical strength but low corrosion resistance

Although pure aluminum has good corrosion resistance, its mechanical strength is poor, which restricts the application of aluminum to a certain extent. Therefore, people add appropriate amounts of magnesium, copper, zinc and other metals to aluminum to make various types of aluminum alloys. Aluminum alloy greatly improves the mechanical strength of aluminum and greatly expands the application range, but its corrosion resistance is worse than that of pure aluminum, so it may be corroded due to oxidation, and the wear resistance of aluminum alloy is not good, so a kind of Wear-resistant coatings for aluminum alloy doors and windows to solve the above problems

[0004] In the patent document with the publication number CN106221521A, a wear-resistant coating for doors is disclosed, which is made of the following materials in parts by weight: 45-50 parts of polyester resin, 16-20 parts of molybdenum disulfide, graphite powder 24-30 parts, 9-15 parts of copper oxide powder, 23-28 parts of quartz powder, 7-10 parts of mica powder, 5-10 parts of reduced iron powder, 22-25 parts of sodium tetraborate, 1-5 parts of calcium dihydrogen phosphate 4-7 parts of paraffin, 6-10 parts of phosphate ester, 13-18 parts of fluorine oil, 7-20 parts of sodium carboxymethyl cellulose, 6-8 parts of polyacrylamide, 9-12 parts of citric acid, silane 23-28 parts of joint agent, 35-40 parts of titanium dioxide, 2-10 parts of carbon black, 6-8 parts of lithopone, 12-17 parts of polyvinyl alcohol and 16-20 parts of sodium cellulose. The grinding coating has the function of dehumidification, good adhesion, good wear resistance and long service life; however, the preparation of this invention is complicated, and the wear resistance and other physical properties can still be further enhanced
