Abstract

The invention discloses an outer protective paint of a glue-injection aluminum alloy profile and a preparation method of the outer protective paint and relates to the technical field of aluminum alloy production. The outer protective paint is prepared from the following materials in parts by weight: acrylate resin, mica powder, red gold powder, polypropylene adipate, dimethicone, isocyanate, phthalic anhydride, zinc pyrithione, ethyl palmitate, an anti-aging agent, diethylene glycol monobutyl ether, a VAE emulsion, ammonium persulfate, lithium bentonite, potassium acetate and pentachlorophenol ketone. The method comprises the steps of (1) fully mixing materials except for a liquid material, stirring and dispersing at 600-650r/min for 10-20min; (2) mixing and stirring the materials in the step (1) and the remaining material, heating the mixture to 90-110 DEG C and lasting for 1-2h; (3) cooling the materials in the step (2) to 50-60 DEG C and carrying out heat preservation for 20-30 minutes; and (4) cooling to a room temperature, lastingly grinding the materials into gel, sealing and carrying out vacuum storage. The outer protective paint is convenient to produce, reasonable in ratio, waterproof, heat-resistant, long in service life, high in caking property, not easy to fall off and low in production cost.

Description

technical field [0001] The invention relates to the technical field of aluminum alloy production, in particular to a protective coating for the outer layer of a glue-injected aluminum alloy profile and a preparation method thereof. Background technique [0002] Aluminum alloy profiles are the most widely used non-ferrous metal structural materials in the industry, and have been widely used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, construction, decoration and chemical industries. With the rapid development of science and technology and industrial economy in recent years, the demand for welded structural parts of aluminum alloys is increasing, and the research on the weldability of aluminum alloys is also in-depth. [0003] Injection heat-insulating aluminum alloy profile is a product that injects rubber and plastic inside the aluminum alloy profile, and the external paint and coatings of the heat-insulating aluminum alloy profile will fall of...
