Efficient water-based mold release agent for aluminum alloy die casting

Abstract

The invention relates to an efficient water-based mold release agent for aluminum alloy die casting. The efficient water-based mold release agent for aluminum alloy die casting comprises, by mass, 10%-18% of modified organic polysiloxane, 3%-6% of bee wax, 2%-5% of oxidized polyethylene wax, 1%-2% of Span80, 3%-8% of OP-10, 0-0.8% of heteropolysaccharide biopolymer thickening agent, 0.05%-0.2% of2,6-di-tert-butyl-4-methylphenol, 0.1%-0.2% of sterilizing preservative, 0.05%-0.1% of antifoaming agent and the balance water. The water-based emulsion mold release agent is high in stability, the high-temperature wetting temperature is 320 DEG C, and the film forming property is good, the efficient water-based mold release agent can easily form a uniform lubricating film having a certain strength on the surface of metal, and effective lubricating agents achieve stable and continuous gas formation at high temperature; trial application to complicated aluminum alloy die casting production shows that the mold release effect is good, and the surface of the casting is smooth and clean.

Description

technical field [0001] The invention belongs to the field of release agents and relates to aluminum alloy die-casting, in particular to a high-efficiency water-based release agent for aluminum alloy die-casting. Background technique [0002] Water-based mold release agent is widely used in aluminum alloy die-casting production due to its advantages such as good mold release, less pollution, less pores and smooth surface of the resulting casting, adjustment of mold temperature to improve mold life, and automatic operation. Aiming at the common problems of poor release effect and performance stability of domestic water-based release agents, the research was carried out from the aspects of release agent formulation and preparation process determination, release agent performance testing and actual production trials. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a high-efficiency water-based...
