Mold release agent

Abstract

The invention discloses a mold release agent which comprises the following components in parts by weight: 5-13 parts of paraffin, 2-6 parts of stearic acid, 3-7 parts of potassium hydroxide, 4-8 parts of fatty alcohol polyethenoxy ether, 5-9 parts of aluminum dihydrogen phosphate, 2-7 parts of graphene, 3-9 parts of epoxy resin, 8-15 parts of zinc dialkyl dithiophosphate and 2-5 parts of coupling agent. The mold release agent has the advantages of simple preparation process and high isolation performance; and the mold release agent has certain adhesive, but can release the product smoothly.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a release agent. Background technique [0002] The release agent is a functional substance between the mold and the finished product. It is an interface coating used on the surface of two objects that are easy to adhere to each other, which can make the surface of the object easy to release, smooth and clean. In the field of plastic products, the release agent can be applied to the cavity surface of the mold to separate the product from the mold smoothly. The quality of the release agent directly affects the quality of the product. Therefore, it is particularly important to develop a release agent with good lubricity, high temperature resistance and high stability. [0003] At present, most of the existing isolation and release agents at home and abroad are pure mineral oils, emulsified oils, paraffins, fatty acids, etc. Some of these isolation and release agents ar...

AI Technical Summary

Problems solved by technology

Some of these isolation and release agents are not easy to dry, and are easy to contaminate the surface of steel bars and concrete. Greatly increased project costs

Some release agent raw materials are lacking, or the cost is too high, so it is difficult to popularize and apply
