Embodiment 1-3

[0040]Embodiment 1-3: A multi-purpose neutral release agent, the ingredients and formula are shown in Table 1, prepared by the following process:

[0041] S1: Weigh the polyethylene glycol of the recipe amount, add the ethanol of the recipe amount, stir evenly, then add the nonionic emulsifier of the recipe amount and stir until dissolved as component A;

[0042] S2: Weigh the formulated amount of simethicone oil, add the formulated amount of soybean emulsified honey and stir, then add the formulated amount of nonionic surfactant and stir evenly as component B;

[0043] S3: Weigh the water of the formula amount, add the anionic surfactant and the complexing agent of the formula amount, stir and dissolve evenly as component C;

[0044] S4: Slowly add component A and component B to component C under high-speed stirring at 2800rpm, and stir at 78-84°C for 60 minutes to obtain a milky white substance, which is a multi-purpose neutral release agent;

[0045] Among them, the molecu...

Abstract

The invention discloses a multipurpose neutral mold release agent and a preparation method thereof. The multipurpose neutral mold release agent is composed of the following substances in percentage by weight: 2.0-4.0% of polyethyleneglycol, 1.0-2.1% of nonionic emulsifier, 15-30% of ethanol, 10.0-15.0% of dimethyl silicon oil, 2.0-4.0% of soybean emulsified honey, 3.5-8.0% of nonionic surfactant, 2.5-4.5% of anionic surfactant, 0.1-0.5% of complexing agent and 63.9-31.9% of water. The multipurpose neutral mold release agent disclosed by the invention has the advantages of environment friendliness, high stability, favorable demolding effect and the like.

Description

technical field [0001] The invention relates to injection molding demoulding, rubber molding demoulding and metal casting demoulding technologies, in particular to a multi-purpose neutral demoulding agent and a preparation method thereof. Background technique [0002] Metal, rubber, plastic and other products are molded and processed in the mold, and the cured product is in contact with the surface of the mold. Due to micro-defects such as unevenness on the working surface of the mold, there will be a certain friction resistance when the product is peeled off from the mold. Or the two are bonded due to physical adsorption or chemical bonding, which makes it difficult to peel off the mold after the product is formed. In order to weaken the adsorption or bonding between the product and the mold, it is necessary to use a release agent. The working principle of the external-coated mold release agent is that the mold release agent forms a smooth and dense film on the surface of ...
