Abstract

The invention relates to a BOPET matte release film, which comprises a polyester base material and a release layer laminated on the surface of one side of the polyester base material. The release layer is characterized by being prepared by painting and curing a coating liquid. The release layer coating liquid comprises the following raw materials in parts by weight: 2.0 to 3.3 parts of fluorine resin, 3.0 to 5.3 parts of polyester polyol resin, 0.5 to 1.7 parts of aldehyde-ketone resin, 1.5 to 3.0 parts of curing agent, 0.2 to 0.6 part of auxiliary agent, 2.1 to 3.5 parts of matting agent, and12.0 to 18.5 parts of mixed solvent, wherein the mixed solvent is prepared by mixing benzene, glycol, 2-heptanone, and cyclohexanone according to a volume ratio of 1:0.7:1.5:0.5; the auxiliary agentis formed by mixing a dispersant and an antistatic agent; and the curing agent is prepared by mixing amino resin and enclosed isocyanate. The provided matte release film has a good peeling property.

Description

technical field [0001] The invention relates to a release film, in particular to a BOPET matte release film. Background technique [0002] Release film, also known as peeling film, isolation film, etc., refers to a film with a separable surface. The release film is not sticky or slightly sticky after contacting a specific material under limited conditions. At present, the products on the release film market are generally based on PET tape base, and the surface is coated with a release agent layer as the main body, which protects the subsequent coating, and can be torn off when used. [0003] However, 95% of the current coating materials in the market are made of silicone coatings. With the wide application in the market, silicone is still not suitable for some fields. For example, it is generally not suitable for materials containing silicone in the electronic circuit manufacturing industry. , because the residual silicone bonded during peeling will indirectly affect the no...
