Organic silicon release agent for artificial board and preparation method of organic silicon release agent

Abstract

The invention belongs to the technical field of release agents, and relates to an organic-silicone-based release agent, in particular to an organic silicone release agent for an artificial board and apreparation method of the organic silicon release agent. The organic silicon release agent is prepared from the compositions in percentage by mass: 4-8% of organic silicone resin, 2-6% of methyl silicone oil, 0.2-1% of an accelerator, 0.2-1% of a masking agent, and the balance isopropyl alcohol, wherein the isopropyl alcohol is a solvent; the organic silicone resin is any one or more of methyltrichlorosilane, dimethyldichlorosilane, phenyltrichlorosilane, and diphenyldichlorosilane; the accelerator is any one of tetrabutyl titanate, dibutyltin dilaurate, bismuth laurate and stannous isooctanoate; and the masking agent is any one or more of N,N-Dimethylisopropanolamine, ethylenediamine, triethylamine, triethylenediamine. The organic silicone release agent is liquid at room temperature, andhas the advantages of small surface tension, low stress during release, good release durability, high temperature resistance, non-toxicity, low cost, good glossness after releasing and non-mold-contaminating.

Description

technical field [0001] The invention belongs to the technical field of release agents, and relates to an organosilicon-based release agent, in particular to an organosilicon release agent for wood-based panels and a preparation method thereof. Background technique [0002] During the production of wood-based panels, there will be adhesion between the hot-pressed film and the slab in the hot press, which is the so-called sticking phenomenon, which will affect product quality and production efficiency in severe cases. In order to weaken the adsorption or bonding between the plate product and the hot-pressed plate, an additive that can form an effective isolation film-a release agent is often used. The release agent is used on the surface of two objects that are easy to stick to each other to form an interfacial film layer to separate the adhesive from the adherend, so that it is easy to peel off and make the release of the plate product easier and more convenient.

Problems solved by technology

[0003] Most of the release agents used at home and abroad are mineral oils, fatty acids, emulsified oils, etc., and there are many types of release agents used in the wood-based panel industry. Some of these release agents are not environmentally friendly, and some are easy to pollute the mold. , some have a longer curing time and are not easy to dry, some are not resistant to high temperature, etc.

These reasons will cause the surface of the board to be polluted or the demoulding is not clean, which will directly affect the quality and appearance of the wood-based panel.
