Abstract

The invention provides a preparation method of a mold release agent durable in storage. A mold release agent product is obtained by adding (heptadecafluoro-1,1,2,2-tetradecyl)trimethoxysilane, poly(ethylene glycol) methyl ether meth-acrylate, poly-4-methyl-1-amylene, methyl isobutyl carbinol, hydroxypropyl methylcellulose phthalate, 5,7-difluoro-2,3-dihydrobenzofuran and N-(tert-butoxycarbonyl)-1-[(4-methylphenyl)sulfonyl]-L-histidine in an agitated vessel to be stirred and diffused.

Description

Technical field [0001] The invention relates to a method for preparing a release agent, in particular to a method for preparing a storage resistant release agent. Background technique [0002] The release agent is a coating applied between the casting and the mold, and its function is to make the surface of the casting product smooth and easy to leave the mold. Alloy metal products, such as alloy equipment parts, automobile manufacturing related products, etc., require higher temperatures during die casting, and higher heat resistance is required for corresponding release agent products. At present, the most widely used release agent product is the water-based emulsion release agent, which has better heat resistance and can be widely used in the die casting of larger metal castings. [0003] CN100571926 discloses a mold release agent used in die casting industries such as aluminum alloys, and particularly relates to a heat-resistant mold release agent, which contains 0.1-50% by we...
