Preparation process of adhesive-residue-preventing adhesive tape

Abstract

The invention discloses a preparation process of an adhesive-residue-preventing adhesive tape. The process comprises the following steps: uniformly mixing 300 parts of methyl vinyl silicone rubber, 30 parts of polyisoprene rubber, 25 parts of silicone resin, 4 parts of vinyl silicone oil, 0.5 part of hydrogen-containing silicone oil, 2.5 parts of 3-thiocyano propyl triethoxy silane, 0.3 part of 2-aminobenzimidazole, 3.8 parts of nano graphite powder, 2 parts of monododecyl phosphate potassium, 400 parts of toluene and 300 parts of ethyl acetate, stirring for 30-60 minutes, then adding 2 parts of methyl butynol, 1 part of a platinum catalyst and 0.7 part of cyclohexanone peroxide, and stirring for 10-20 minutes to prepare an organic silicon adhesive; and uniformly coating the surface of a base material layer with the organic silica gel adhesive, and curing at 140-150 DEG C to form an organic silica gel layer, so as to obtain a semi-finished product of the protective film. The antistatic effect of the prepared adhesive tape is remarkably improved, and the surface resistivity reaches below 10<7> ohms.

Description

technical field [0001] The invention relates to the field of protective films, in particular to a preparation process of an anti-residue adhesive tape. Background technique [0002] With the development of science and technology, electronic products play an increasingly important role in people's lives, and various electronic products need to process components such as frames. During the processing, a protective film is needed to fix and protect the components of electronic products. At present, this kind of protective film comes from foreign suppliers. Domestic products have the following technical problems and cannot replace imported products. The main problems are: 1. The viscosity is too low or too high, so that the edge warps or even falls off during use. , or produce residual glue during removal; 2. The base material is too hard or too soft, so that it is easy to warp or break; 3. The antistatic effect is not good, which affects automatic continuous production. There...
