Corrosion-resistant aluminum alloy door frame

Abstract

The invention discloses an abrasion-resisting aluminum alloy door frame. The abrasion-resisting aluminum alloy door frame comprises an aluminum alloy body and a protection coating, wherein the surface of the aluminum alloy body is coated with the protection coating. The aluminum alloy is formed by fusing aluminum and copper at the high temperature. The protection coating is composed of ethylene propylene rubber, a dispersing agent, a filling agent and tackifier. The dispersing agent is the ethylene-ethyl acrylate copolymer. The filling agent is talcum powder. The tackifier is N'-ethylene hisstearamide. The protection coating comprises, by mass, 66%-81% of ethylene propylene rubber, 3%-8% of ethylene-ethyl acrylate copolymer, 15%-21% of talcum powder and 1%-5% of N'-ethylene hisstearamide. The aluminum alloy body is stable in performance, and due to the fact that the surface of the aluminum alloy body is coated with the protection coating, the aluminum alloy body has the advantages of being good in corrosion resistance, high in strength, stable in quality, low in cost and good in using effect.

Description

technical field [0001] The invention relates to an aluminum alloy door frame, in particular to a door frame for corrosion-resistant aluminum alloy. 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 object of the present invention is to provide a corrosion-resistant ...
