Abstract

The invention discloses a formula of transparent high-viscous insulating tape. The insulating tape is prepared from, by weight, 30-50 parts of butyl acrylate, 15-30 parts of methyl vinyl silicone rubber, 10-20 parts of rosin resin, 5-10 parts of viscosity thickening agent, 3-8 parts of hydroxy silicone oil, 5-12 parts of micron silicon dioxide powder, 3-8 parts of nanometer aluminium oxide powder, 2-4 parts of coupling agent, 1-3 parts of initiator and 5-20 parts of solvent. The formula contains both butyl acrylate and methyl vinyl silicone rubber, so that butyl acrylate has the characteristics of rubber, the tape is given excellent anti-aging properties, long-term good stickiness is ensured; micron silicon dioxide powder and nanometer aluminium oxide powder have a synergistic effect in the formula, discoloration in the tape from long-term use is better prevented, and transparent status (light transmission rate up to 90% or above) is maintained, so that the product looks more attractive.

Description

technical field [0001] The invention relates to a tape formula, in particular to a formula of a transparent high-viscosity insulating tape; it belongs to the technical field of tapes. Background technique [0002] With the rapid development of electronic products and smart terminals, the application of touch screens has become more extensive. During the manufacturing and processing of electronic products, various adhesive tapes need to be used as shielding protection to play a good insulating role. At present, there are two types of common insulating tapes, one is a high-voltage insulating tape made of two kinds of rubber sheets, and the other is a self-adhesive rubber tape mainly made of butyl rubber. Both have the problems of complicated process, easy deterioration and failure at high temperature, and the adhesive tape itself is opaque, which may affect the aesthetics of electronic products. [0003] In order to meet the needs of the high-end market, new products such as ...
