Problems solved by technology

Although the existing PVC wire harness tapes can meet the temperature resistance requirements, the adhesive in the PVC tape is easy to dissolve at high temperature, and it is easy to produce a large amount of residual glue, which is difficult to meet the requirements of the automotive industry for the low amount of residual glue in the wire harness tape.

Abstract

The invention belongs to the technical field of wire harness adhesive tapes, and particularly relates to a high-temperature-resistant automobile wire harness adhesive tape. The adhesive tape comprises an adhesive surface layer, and the adhesive surface layer comprises the following components in percentage by weight: 13-16% of natural rubber, 0.2% of zinc oxide, 0.2% of hydrocarbon resin, 0.2% of a rubber accelerator, 0.2-0.4% of an antioxidant, 10-14% of petroleum resin, 3-5% of terpene resin, 2-4% of phenolic resin and 68% of methylbenzene. The high-temperature-resistant automobile wire harness adhesive tape provided by the invention can be suitable for a working environment of 125 DEG C, and has the characteristics of high adhesive tape performance and low residual adhesive rate.

Description

Technical field [0001] The present invention belongs to the technical field harness tape, in particular, to high temperature automotive wiring harness tape. Background technique [0002] Tape automotive wiring harness, the wire harness is wound specific to the automotive industry, the different performance thereof is not nearly the same as the requirements of the winding position. Specifically, temperature resistance according to temperature environment selection, cabin temperature requirements for the tape 105 ~ 150 ℃, the cab is required is 85 ~ 105 ℃. Although conventional PVC wire harness tape can meet the heat resistance requirements, but PVC tape is easily dissolved at a high temperature adhesive, easy to produce large amounts of adhesive residue is difficult to meet the automotive industry for harness tape low amount of the residual gum. Inventive content [0003] In order to overcome the drawbacks of the prior art, the present invention is to solve the technical problem ...
