Abstract

A liquid demoulding coating for precise die casting of aluminum alloy mainly comprises (by weight percentage) 70-85% of mineral oil selected from machine oil, hydraulic oil, diesel oil and gasoline, 25-35% of silicone oil (preferably, water-soluble silicone oil) and water and a proper amount of emulsion. The liquid coating not only has excellent lubrication effect on aluminum alloy casting chamber and facilitates demoulding, but also effectively cools the aluminum alloy casting chamber and improves product quality.

Description

Technical field [0001] The invention belongs to the technical field of release coatings for die-casting, and in particular relates to a liquid release coating for aluminum alloy die-casting that can lubricate and cool aluminum alloy die-casting machine molds. Background technique [0002] During the use of aluminum alloy die-casting molds and the demoulding process of die-casting workpieces, lubrication and cooling are required to reduce mold wear and improve the quality of aluminum alloy workpieces. At present, the method of spraying paint on the mold part is mostly used. There are imported and domestic paints of this kind. Imported paints are effective, but the price is relatively high. Although the price of domestic paints is low, most of them are of poor quality. . Contents of the invention [0003] Aiming at the above-mentioned shortcomings in the prior art, the present invention provides a liquid paint for aluminum alloy die-casting, which not only has a good lubri...
