Aluminum alloy water-based mold release agent and preparation method thereof

Abstract

The invention relates to an aluminum alloy water-based mold release agent. Raw materials of the aluminum alloy water-based mold release agent comprise methylsilicone oil, polyvinyl alcohol, SPAN60, sodium dodecyl sulfate, fatty alcohol-polyoxyethylene ether, ethylparaben, urotropin, methylcellulose, zinc oxide, water glass and antifoaming agent. All the components are weighed by measurements, and are evenly mixed; then, water of 15 times of the weight is added for evenly mixing to obtain the finished product; the mold release agent can be coated, brushed and dipped on the inner edge surface of a metal mold by a spray gun, is excellent in high-temperature lubrication performance, has no need to frequently overhaul the mold, can prolong the service life of the metal mold, and saves the labor hour; and a die casting is smooth and bright in surface, and is clear in outline.

Description

technical field The invention belongs to the technical field of aluminum alloy manufacturing, in particular to an aluminum alloy water-based release agent and a preparation method thereof. Background technique Aluminum alloy is a general term for alloys based on aluminum. The other metal elements involved mainly include copper, silicon, magnesium, zinc and manganese, and mainly nickel, iron, titanium, chromium and lithium. The density of aluminum alloy is low, but its strength is relatively high, which is close to or exceeds that of high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance, and has been widely used in industry. Its consumption is second only to steel. In the production process of aluminum alloy castings, die casting is a precision casting method that uses high pressure to press aluminum alloy melt into a metal mold with complex shape and coo...

AI Technical Summary

Problems solved by technology

The above-mentioned aluminum alloy die-casting needs to be demolded after production. In order to ensure that the casting is easy to take out, a release agent must be applied to the inner edge of the metal mold. Water-based release agents are more commonly used, but the existing formulations are more random, and the surface of the casting will be somewhat affected
