Problems solved by technology
At present, most of the mold release lubricants produced in China have relatively high surface roughness, resulting in the occurrence of sand sticking, sand inclusions, and blisters in injection molded parts. The surface finish after processing is poor, and it also increases the difficulty of mold cleaning.

The invention discloses a demoulding lubricating oil which comprises the following materials in parts by weight: 10-30 parts of indanthrene blue RS, 4-6 parts of low-molecular polyethylene wax, 50-60 parts of solvent oil, 1-2 parts of diatomite, 1-3 parts of silica gel, 3-5 parts of colloidal graphite, and 2-3 parts of nonyl(octyl)phenol polyoxyethylene ether. The demoulding lubricating oil has the benefits that the surface roughness of a processed workpiece is effectively reduced, the defects of sand adhesion, sand inclusion, sand hole and the like of a cast can be effectively prevented, the effects of improvement of the surface finish degree of the cast and simplicity and convenience in mould cleaning are achieved, and in addition, the demoulding lubricating oil has heat resistance, and is free of carbonization decomposition after being heated, stable in chemical property, free of chemical reaction with a formed product, and free of influence on secondary processing performance of plastic.
Description
technical field [0001] The invention relates to a mold release lubricating oil. Background technique [0002] The release agent is a release lubricant for injection molds or molten steel casting molds. It is usually divided into powder, semi-solid and liquid. The powder and semi-solid can be applied to the surface of the mold with a brush or by hand like wax. The liquid can be applied to the surface of the mold with tools such as spray or brush to form an isolation film. Liquid release agents are preferably sprayed on. In order to prevent environmental pollution, it is necessary to choose a release agent that is not easy to burn, has low odor and toxicity. In the selection of release agent, economy is an important factor that cannot be ignored. Poor quality release agent will cause cracks and wrinkles on the surface of the product, affect the appearance of the product and the service life of the mold, and cause environmental pollution. Choose a high-quality spray release ...
