Preparation method of oily antirust demolding agent

Abstract

The invention relates to the technical field of preparation of demolding agent compositions, in particular to a preparation method of an oily antirust demolding agent. The preparation method comprisesthe following steps of using ginkgo kernels as the raw material, and pulping, so as to obtain a kernel pulp; adding a sodium chloride solution, cellulase and water into the kernel pulp, so as to obtain a kernel extracting solution; treating by ultrasonic waves, centrifuging and separating, so as to obtain ginkgo oil; adding a mixed solution of formaldehyde and acetophenone into a reflux solution,so as to obtain a corrosion inhibitor of a main body; mixing the corrosion inhibitor of the main body with benzyl chloride, so as to obtain a film forming antirust agent; mixing the film forming antirust agent, methenamine, gingko oil, and the like, and dispersing and emulsifying at high speed, so as to obtain the oily antirust demolding agent. The oily antirust demolding agent has the advantagesthat after the oily antirust demolding agent is covered on the surface of metal, the ability of blocking and absorbing oxygen in air is high; the gingko oil can be chelated with one part of oxidizedmetal, so that the adhesion force of the oily antirust demolding agent to the metal is increased; after mannich base is quaternized, and is in contact with the surface of the metal, the active energyin corrosion and rusting reaction is increased, and the application prospect is broad.

Description

technical field [0001] The invention relates to the technical field of preparation of release agent compositions, in particular to a preparation method of an oily antirust release agent. Background technique [0002] A release agent is an interface coating applied to the surface of two objects that tend to stick to each other, which makes the surface of the object easy to release, smooth and clean. The release agent not only affects the surface properties of the composite material, but also relates to whether the product can be released from the mold, no matter how important the product and the mold are, if the product sticks to the mold and cannot be released from the mold, the product and the mold can only Scrap, so the role of the release agent is extremely important. [0003] A good release agent should have good lubrication and release performance, good cooling and heat insulation, strong lubricating performance, the release agent also has heat and stress resistance, i...

Problems solved by technology

[0011] The main technical problem to be solved by the present invention is to provide an oily anti-rust release agent for the defects that the steel mold is prone to wear and tear when in contact with air under high heat conditions when the current release agent is used for steel plate demoulding, and the steel plate will also be corroded.
