Embodiment 1
[0039] A low-cost and high-environmental protection release film, including a PET substrate and a silicone oil coating,
[0040] Described silicone oil coating comprises each component of following parts by weight:
[0065] Calculated in units of one year, a customer coats about 10,000 square meters of protective film every day. The original silicone tape needs to be coated with a thickness of 8um. After using the release film of the present invention, only 1um is coated, and the cost is only 8 / 1 of the original , the original cost per square meter was only 1.6 yuan, but now it only needs 0.2 yuan, and the annual cost savings is about 1.6*10000*30*12-0.2*10000*30*12=5.04 million, and the production process and efficiency are greatly improved. The most important thing i...

Abstract
The invention discloses a low-cost high-environmental-protection release film, which comprises a PET base material and a silicone oil coating, and the silicone oil coating comprises the following components by weight: 100 parts of silica gel, 10-30 parts of silicone oil, 1-1.2 parts of a cross-linking agent, 0.6-1.0 part of an adhesion additive, 1-1.2 parts of a platinum catalyst, and 180-200 parts of toluene. The formula of the release film contains silicone oil, the coating thickness is small, the technological process is good, the cost is low, the viscosity is not large, the surface initialadhesive force is very large, graphene can be borne, a user can easily peel off graphene from the release film, the production efficiency is greatly improved, and the release film is environmentallyfriendly and saves energy and materials.
Description
technical field [0001] The invention relates to a low-cost, high-environmental protection release film. Background technique [0002] The surface polarity of graphene material is low, and silica gel tape is usually used to carry graphene. However, due to the limited ability of silica gel tape to carry graphene, it is necessary to increase the coating thickness to achieve the effect of high initial adhesion on the surface. Even in this way, the phenomenon of graphene falling from the silicone tape will still occur, resulting in a high defect rate and increased production costs. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects that the release film silica gel belt used for carrying graphene in the prior art has poor load-carrying capacity and graphene is easy to drop, and provide a low-cost and high-environmental protection release film. [0004] In order to solve the problems of the technologies descr...
