Abstract

The invention discloses a preparation method of an environment-friendly emulsified releasing agent. The environment-friendly emulsified releasing agent comprises the following raw materials by mass, 15-25 parts of simethicone, 5-8 parts of polyvinyl alcohol, 6-9 parts of ricinoleic acid, 3-6 parts of dimer fatty acid, 5-7 parts of assistant emulsifiers, 6-10 parts of hydroxyalkyl ammonium, 0.6-1.0 part of organic dicarboxylic acid, 0.05-0.1 part of bactericide and 45-60 parts of deionized water. By adopting the film forming mode that a primary emulsifier and an antirust agent are synthesized by organic acid and hydroxyalkyl ammonium, in company with the assistant emulsifiers, simethicone is emulsified in the deionized water and polyvinyl alcohol, the external-use emulsified releasing agent is mainly used for epoxy resin and unsaturated polyester material forming dies, and is sprayed to the surfaces of the dies for use, so that the effects that epoxy resin and unsaturated polyester products are easy to form, do not corrode the dies, and are not bonded with the dies are reached; and the environment-friendly emulsified releasing agent has the characteristics that no decomposition residues exist, the colors and performances and the products are not affected, the cleaning property is good and no pollution to environment is caused.

Description

technical field [0001] The invention relates to the technical field of release agents, in particular to a preparation method of an environmentally friendly emulsifying release agent. 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 the mold...
