Aerosol can type plastic mould parting agent and manufacturing method thereof

Abstract

The invention discloses a high-generality aerosol can type plastic mould parting agent capable of meeting comprehensive technical index requirements and a manufacturing method thereof. The aerosol can type plastic mould parting agent is manufactured from the following raw materials in mass ratios: 5-10 of barium petroleum sulfonate, 3-5 of aluminum stearate, 20-30 of castor oil, 60-90 of 10# machine oil, 20-40 of trolamine, 20-40 of oleic acid, 10-20 of polyethylene glycol and 180-300 of absolute ethyl alcohol. The manufacturing method comprises the following steps: adding the measured absolute ethyl alcohol to a sealed stainless steel reaction kettle at a normal temperature and a normal pressure; starting a stirrer with a rotation speed of 60 revolutions / min; slowly adding the 10# machine oil, the castor oil, the aluminum stearate and the measured barium petroleum sulfonate to the reaction kettle in sequence, and stirring the mixture for sufficient dissolution; slowly adding the measured trolamine, the measured oleic acid and the measured polyethylene glycol to the reaction kettle in sequence, and stirring the mixture for sufficient dissolution; and sealing the reaction kettle, and stirring the mixture to form a light brown solution.

Description

technical field [0001] The invention relates to a plastic mold release agent and a manufacturing method, in particular to an aerosol can-type plastic mold release agent and a manufacturing method that can meet the requirements of comprehensive technical indicators and have strong versatility. Background technique [0002] Most of the plastic products are molded by injection molding machine heating and pressing through the mold, and a release agent must be used on the contact surface between the mold and the plastic product. Surface finish and brightness. For this reason, the performance requirements for the release agent must have the following comprehensive technical indicators: [0003] Release property: After injection molding, the degree to which the plastic product workpiece and the mold can be effectively separated; [0004] Lubricity: It can significantly reduce the friction coefficient and friction force between the concave-convex arc surface of the pressed plastic...

AI Technical Summary

Problems solved by technology

[0014] Due to different types of plastic products, different materials, different strengths and thermal expansion coefficients, it is difficult for existing release agents to meet the requirements of versatility

Under the same operating conditions, some plastic workpieces may not be easily released from the mold, the surface finish and smoothness of the workpiece are low, and there are many residues on the surface of the working cavity of the mold.
