Abstract

The invention discloses a release agent for aluminum alloy casting. The release agent is mainly prepared from the following raw materials in parts by weight: 8-10 parts of graphite lubricating oil, 6-8 parts of a slipping agent, 4-6 parts of a lotus leaf water repellent agent, 3-5 parts of methyl modified silicone oil, 2-3 parts of an organic silicon defoamer, 18-24 parts of butyl-3-methylimidazolium hexafluorophosphate, 50-60 parts of deionized water, 1-2 parts of a heat stabilizer and 0.6-0.8 part of a flow promotor. The invention provides a preparation method for the release agent for aluminum alloy casting. According to the release agent and the preparation method thereof, through the graphite lubricating oil and the methyl modified silicone oil, the lubricity of the release agent is improved, in addition, the high-temperature resistance is improved, moreover, through ER erucyl amide, octadecanamide and the lotus leaf water repellent agent, the anti-adhesion property, the lubricityand the anti-static property of the release agent can be improved, the release agent is smoother, the fluidity is improved through the flow promotor and vegetable fat, the uniform smoothness of the release agent is improved, and the phenomenon that the use next time is influenced due to the fact that the release agent is retained and adheres to the wall can be avoided.

Description

technical field [0001] The invention relates to the field of release agents, in particular to a release agent for aluminum alloy casting and a preparation method thereof. Background technique [0002] Mold release is an important step in the casting process, which is directly related to the quality of the casting, and the release agent is an interface coating used on the surface of two objects that are easy to adhere to each other. It can make the surface of the object easy to detach, smooth and clean. Therefore, the release agent is directly related to the quality of the casting. The currently used low-pressure casting mold release agent has the disadvantages of poor heat resistance and poor lubrication effect, which leads to poor mold release effect and poor protection effect on the inner wall of the mold, which will not only affect the quality of the casting, but also shorten the life of the mold. [0003] Therefore, it is necessary to invent a release agent for aluminu...
