Abstract

The invention discloses an environmentally friendly emulsified release agent, which comprises the following raw materials in parts by mass: 15-25 parts of dimethyl silicone oil, 5-8 parts of polyvinyl alcohol, 6-9 parts of ricinoleic acid, and 3-6 parts of dimer fatty acid 5-7 parts of co-emulsifier, 6-10 parts of hydroxyalkylamine, 0.6-1.0 part of organic dicarboxylic acid, 0.05-0.1 part of fungicide, 45-60 parts of deionized water; Synthetic main emulsifier and antirust agent with base amine, supplemented by co-emulsifier to emulsify simethicone oil in deionized water and polyvinyl alcohol to form a film, providing a method mainly used for epoxy resin and unsaturated polyester materials Emulsified mold release agent for external use of forming molds, sprayed on the surface of molds, to achieve the effect of easy molding of epoxy resin and unsaturated polyester products, no corrosion of molds, no bonding with molds, no residual decomposition products, and no influence on products Color and performance, good cleaning, no pollution to the environment and so on.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to an environmentally friendly emulsified release agent and a preparation method thereof. Background technique [0002] The release agent is a functional substance between the mold and the finished product. 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 release, smooth and clean. It is an indispensable additive to prevent the formed composite product from sticking to the mold, improve production efficiency, prolong the service life of the mold, and at the same time make the surface of the product smooth, the size is qualified, and reduce defective products. In industrial production, during the molding process of some molding materials such as epoxy resin and unsaturated polyester, it is required to have a certain thermal stability when demolding, not to corrode ...
