A kind of water-based aluminum alloy die-casting mold release agent and preparation method thereof

Abstract

The invention discloses a water-based aluminum alloy die-casting mold releasing agent. The water-based aluminum alloy die-casting mold releasing agent is prepared from the following components in percentage by mass: 100 to 150 parts of modified organic silicone oil, 10 to 20 parts of oxidized polyethlene wax, 10 to 15 parts of isotridecanol polyoxyethylene ether, 8 to 10 parts of long-chain fatty alcohol polyoxyethylene ether, 10 to 15 parts of tween and 500 to 800 parts of deionized water. In addition, the invention also discloses a preparation method of the water-based aluminum alloy die-casting mold releasing agent. The preparation method comprises the following steps of firstly, heating and melting the long-alkyl-chain phenyl modified organic silicone oil, the oxidized polyethlene wax, the isotridecanol polyoxyethylene ether, the long-chain fatty alcohol polyoxyethylene ether and the tween; secondly, uniformly stirring the components, and cooling to 55 to 75DEG C; and thirdly, slowly dropping the deionized water in batches and then stirring for half an hour, thus obtaining a finished product. The water-based releasing agent prepared by the preparation method disclosed by the invention can be used for producing die-casting metal products such as an aluminum alloy and is good in releasing performance; and the surface quality of products can be effectively improved, and the smooth finish and the integrity of castings are improved.

Description

technical field [0001] The invention belongs to the technical field of casting paint and its synthesis process, and in particular relates to a water-based aluminum alloy 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 releas...

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

Domestic release agents generally have problems such as poor film finish, unstable emulsion and unstable product quality, which makes some large-scale die-casting manufacturers in China still use imported release agents.
