Problems solved by technology

The second is the domestic mold release agent, which has good mold release performance, but the emulsification effect is not ideal
The die-casting release agents currently produced in China use vaseline and mineral oil as the main raw materials. Compared with imported release agents, carbon deposits are easy to occur during use, which affects the appearance of die-casting parts. The ratio of water to water is low and the release ability is not strong. and other shortcomings

Abstract

The invention provides a die-casting mold releasing agent and a preparation method thereof. The die-casting mold releasing agent is prepared from, by weight, 15%-18% of modified organic silicone oil, 3.2%-4% of oxidized polyethlene wax emulsion, 10%-12% of oleate emulsion, 1%-2% of Turkey red oil, 3%-5% of emulsifier and the balance water. The preparation method comprises the steps that (1), the modified organic silicone oil, the oxidized polyethlene wax emulsion, the oleate emulsion, the Turkey red oil, the emulsifier and the water are weighed according to the proportion for use; and (2), the modified organic silicone oil and the emulsifier are mixed firstly and then put into a high-speed shearing disperser, the silicone oil is emulsified through a reverse emulsifying method at normal temperature to obtain a silicone oil emulsion, then the oxidized polyethlene wax emulsion, the oleate emulsion and the Turkey red oil are added into the silicone oil emulsion, all the materials are mixed to be uniform to obtain a mixed emulsion, and then the mixed emulsion is subjected to homogenization treatment through a high pressure homogenizer, and therefore the die-casting mold releasing agent can be obtained. The die-casting mold releasing agent is good in high temperature resistance, the spray quantity of the mold releasing agent is small, the die-casting circulating period is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of casting coatings, and in particular relates to a die-casting release agent and a preparation method thereof. Background technique [0002] Die casting is an important support for the automotive industry and the electronics industry. Release agent is an essential auxiliary agent for the production of metal die casting products. Its main function is to help the metal die casting product to be removed from the mold, and to maintain the integrity and post-processing of the product. Among them, compared with the traditional oil-based release agent, the emulsion-like water-based release agent has the advantages of good cooling effect, no accumulation, good surface quality of castings, helps to reduce internal pores, and is safe, clean, and pollution-free. , is currently the mainstream product of die-casting release agent. [0003] The metal die-casting release agents in the domestic market are mainly divided...
