Abstract

The invention is applicable to the technical field of mold surface treatment, and provides an anti-adhesive composition, an anti-adhesive treatment method for molds, and a mold. The anti-adhesive composition includes the following components in parts by weight: 5 to 12 parts of zirconia micropowder , 5~18 parts of titanium oxide micropowder, 5~10 parts of yttrium oxide micropowder, 40~70 parts of methyl MQ silicone resin. In addition, the anti-sticking treatment method of the mold includes the following steps: thermally spraying the above-mentioned anti-sticking composition on the surface of the mold by means of supersonic flame spraying. The anti-adhesive composition provided by the present invention can replace the use of high-pollution mold release agents and Teflon to carry out anti-adhesive treatment on the surface of the mold, forming a hard layer on the surface of the mold with low surface peeling force and anti-adhesive Functional anti-stick coating. The anti-adhesive coating also has the advantage of a long service life in a single preparation, and can reduce the production cost of the enterprise while avoiding environmental pollution.

Description

technical field [0001] The invention belongs to the technical field of mold surface treatment, and in particular relates to an anti-adhesive composition, an anti-adhesive treatment method for a mold and a mold. Background technique [0002] The surface of industrial molds often has mold sticking due to the adhesion of production materials. In actual production, spraying mold release agents or high-temperature Teflon coatings are often used to avoid the occurrence of the above phenomena. However, the use of release agent will not only increase the production cost, but also pollute the environment; and Teflon has the problem that the curing temperature is too high and the mold is deformed. [0003] Therefore, there is an urgent need to develop an anti-sticking treatment method for a mold to replace the use of release agents and Teflon. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide an anti-adhesive composition to sol...
