Abrasion-resistant aluminum alloy doorframe

Abstract

The invention discloses an abrasion-resistant aluminum alloy doorframe. The abrasion-resistant aluminum alloy doorframe comprises an aluminum alloy body and an abrasion-resistant coating which is coated on the surface of the aluminum alloy body, wherein the aluminum alloy is formed by fusing aluminum and chromium at high temperature; the abrasion-resistant coating comprises cis-polybutadiene, a filling agent, a plasticizing agent and a coupling agent; the filling agent is aluminum oxide powder; the plasticizing agent is diethylene glycol binary m-methyl benzoate; the coupling agent is isopropyl titanate tristearate; the percentages by weight of components in the abrasion-resistant coating are as follows: the cis-polybutadiene accounts for 57-77%; the aluminum oxide powder accounts for 17-24%; the diethylene glycol binary m-methyl benzoate accounts for 4-11%; the isopropyl titanate tristearate accounts for 2-8%. The aluminum alloy itself is high in mechanical strength; the surface of the aluminum alloy is protected by the abrasion-resistant coating; the aluminum alloy has the characteristics of sagging resistance, abrasion resistance, impossibility in damage, long service life and good using effect.

Description

technical field [0001] The invention relates to an aluminum alloy door frame, in particular to a wear-resistant aluminum alloy door frame. Background technique [0002] The aluminum alloy door frame is a door frame component made of surface-treated aluminum alloy profiles through blanking, drilling, milling, tapping, manufacturing and other processing processes, and then used with connectors, sealing materials and opening and closing hardware accessories Assembled. Because it is directly made of aluminum alloy, it is very easy to be scratched by foreign objects during use, which will cause the entire aluminum alloy door frame to be corroded by air and other substances, resulting in aging and damage of the entire aluminum alloy door frame, and shortening the service life. Frequent replacement of the door frame increases the cost, and the use effect is poor. Contents of the invention [0003] The purpose of the present invention is to provide a door frame for wear-resistan...
