Abstract

An environment-friendly water-based demolding release composition is prepared from, by weight, 4-6 parts of alkyl silicone oil, 8-12 parts of polyvinyl alcohol, 3-5 parts of sulfonated methyl cellulose, 3-5 parts of oxidized polyethlene wax, 1-3 parts of cyclodextrin, 1-3 parts of solvent oil, 2-4 parts of isopropanol, 2-4 parts of dioctyl sodium sulfosuccinate, 8-12 parts of polyacrylamide, 0. 1-1 part of isopropanolamine, 6-10 parts of fatty alcohol polyoxyethylene ether, 0.5-1 part of imidazoline compound, 1-2 parts of isothiazolinone compound and 55-60 parts of deionized water, wherein the polymerization degree of polyvinyl alcohol is 2300-2500, the alcoholysis degree is 87-100%, and the alkyl silicone oil is 3-hexyl trimethyltrisiloxane.

Description

technical field [0001] The invention belongs to the field of aluminum and aluminum alloy processing parts, in particular to a very environment-friendly water-based mold release composition. Background technique [0002] Die casting (referred to as die casting) is a metal casting process. The release composition is a release agent used for stamping aluminum alloys, magnesium alloys, zinc alloys and other metal alloys under high pressure and high speed conditions. Die casting has the characteristics of high production efficiency, short production process, high casting finish and strength, less machining allowance, and saving metal materials. [0003] Die castings have a wide range of applications, involving quite a few product fields and industrial categories. In this application, the automobile industry should be the first to be considered in terms of the large quantity, variety, high requirements, and large amount of metal materials used. Die castings are also widely used ...
