Abstract

The invention discloses a production process of a high-permeability grid release film. The production process comprises the following steps: 1) coating preparation: mixing 120 #, toluene, butanone and isopropanol as a solvent; (2) treating an original film: adopting a transparent PET grid film with the grid size of 0.16 mm * 0.16 mm as the original film, and pre-coating a layer of antistatic liquid on the surface of the original film; (3) precise coating: the coating mode is slit coating; 4) drying and curing; and (5) receiving and rolling. According to the high-breathability grid release film, the 20 min release force is 2-5 g / in, the 24 H release force is 6-10 g / in, the aging force is 10-15 g / in, the residue is larger than or equal to 80%, and the resistance value is 10<9>-10<11>; under a magnifying lens for one hundred times, the grid release film is free of visible particles or foreign matters, free of scratches on the surface, free of obvious rainbow lines, free of coating leakage and free of coating spots, is low in release, high in breathability, high in residue, low in aging and high in breathability, and is suitable for high-end electronic products.

Description

technical field [0001] The invention relates to the technical field of high air permeability grid release film, in particular to a high air permeability grid release film and a production process thereof. Background technique [0002] At present, many electronic products have the problem of not being able to dissipate heat quickly during use. The overheating phenomenon of electronic products during use has potential safety hazards and also affects the service life of the product. The highly air-permeable grid release film has a layer of grid on its surface Structure, in the use process of downstream customers, its grid printing makes the surface layer of the glue coated on the release film have a corresponding grid structure, and this kind of glue with grid printing is used in electronic products, because of its good The space structure makes it have high air permeability, increases its heat dissipation rate, and avoids a series of problems caused by poor heat dissipation du...
