Environment-friendly mold release agent

Abstract

The invention discloses an environment-friendly mold release agent. The environment-friendly mold release agent is prepared by mixing methylsilicone oil, polyvinyl alcohol, span 60, addition agents, water and other components. The environment-friendly mold release agent has the characteristics that operation is safe, pollution is avoided, human health is not damaged, and using is convenient. The environment-friendly mold release agent has the characteristics of being good in stability, free of layering, low in cost and capable of meeting environmental protection requirement which are the same as those of a common mold release agent and also has the functions of sterilization, corrosion prevention and rust prevention. The mold release agent has strong selection adhesive power, can preferentially adhere to a mold without being transmitted to a forming piece and meanwhile has a modification effect on the surface of resin, the resin fluidity is facilitated, and the surface quality of the forming piece is improved.

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to an environment-friendly release agent. Background technique [0002] In industrial production, some plastics such as phenol, epoxy, polyester, and high-pressure polyethylene are difficult to release from the mold. Traditional paraffin or silicone oil cannot meet the requirements, especially in unsaturated polyester, epoxy resin, etc. During the molding process, the selection and application of new release agents has become an indispensable and important content. When demoulding, it is required to have a certain thermal stability, not to corrode the mold, to be chemically inert, not to react with the components in the resin, not to leave decomposition products, not to affect the color of the product, good processability, good cleaning performance, easy to form, and easy to remove. Excellent mold performance, no pollution to the environment, etc. [0003] At present, most of the dom...

Problems solved by technology

[0003] At present, most of the domestic release agents are oils. Oil release agents have few raw materials, high cost, easy to produce oil mist, and the air pollution level at the processing site is high, which is harmful to the health of operators.

The water-soluble release agent is safe to operate, has no oil mist, has little environmental pollution, has little damage to human health, and is easy to use. It has gradually developed into a substitute for oil-based release agents. Most of the water-soluble release agents on the market are For imported products, the price is high, therefore, it is of great significance to develop such products
