A kind of environment-friendly high-efficiency release agent for metal casting and preparation method thereof

Abstract

The invention discloses an environment-friendly and efficient release agent for metal casting. The release agent is prepared from raw materials in parts by weight as follows: 10-14 parts of graphite,1-2 parts of graphene, 3-5 parts of wax powder, 12-16 parts of demolding lubricating powder, 3-5 parts of compound mixed grease, 2-4 parts of polyol ester, 7-9 parts of an organic solvent, 1-2 parts of sodium oleate, 1-2 parts of a fungicidal preservative, 2-4 parts of limestone, 1-2 parts of titanium dioxide, 4-6 parts of a fatty acid derivative and 3-5 parts of a dispersing agent. The problem ofadhesion in the metal casting process is effectively solved, the surface quality of a casting is improved, the release agent has excellent lubricating release property, also does not decompose at thehigh temperature, is easy to release, enables the casting to be smooth and flat, can effectively protect a mold and prolong the service life of the mold and can be widely applied to the metal processing industry. Besides, the raw materials are safe, reliable and easy to obtain, the cost is lower, the process is simple, and the release agent has higher practical value and good application prospects.

Description

technical field [0001] The invention relates to the technical field of metal casting, in particular to an environment-friendly and high-efficiency release agent for metal casting and a preparation method thereof. Background technique [0002] With the development of the national economy, the industry has developed in great strides, and most of the industrial products use metal materials. The release agent is an indispensable auxiliary material in the casting production. The selection and use of the release agent will directly or indirectly affect the die casting. The quality and production efficiency will also have a bad impact on the production environment. [0003] With the rapid development of the die-casting industry, die-casting products are widely used in automobiles, motorcycles, electronic appliances, mechanical instruments, hardware and other industries. Among all these casting applications, the automotive industry is firmly the largest market for the die-casting i...

Problems solved by technology

At present, most of the release agents used in the market are water-based release agents, while the quality of domestic products varies and the prices of foreign products remain high.

In addition, the water-based release agent is prone to carbonization at high temperature and loses the release effect and cannot achieve the heat preservation effect during the casting molding process. At the same time, in order to improve the surface compactness and smoothness of the die-casting parts, it is necessary to have a special for rare earth magnesium alloy die-casting. Release agent for more convenient and quick release, improve the surface compactness and smoothness of die-casting parts, and prolong the service life of the mold
