Abstract

The invention relates to a novel environment-friendly, temperature-resistant and wear-resistant fabric-based adhesive tape produced from an ultraviolet (UV)-cured hot-melt pressure-sensitive adhesiveand a production technology thereof. The pressure-sensitive adhesive tape is produced by directly coating a polyester fabric or non-woven fabric base material with the novel UV-cured hot-melt pressure-sensitive adhesive by using a hot-melt coating machine equipped with an UV lamp, and curing the pressure-sensitive adhesive by UV irradiation in a crosslinking manner; the UV-cured hot-melt pressure-sensitive adhesive is prepared by heating and blending a block copolymer thermoplastic elastomer, tackifying resin, a softening agent, a long-chain alkyl-containing vinyl monomer, a photoinitiator, anantioxidant and other auxiliary agents according to a certain ratio. The fabric-based adhesive tape not only has excellent mechanical properties, adhesive performance, high temperature resistance andfriction resistance, but also is relatively low in hot-melt coating temperature, simple and convenient in production technology and free of environment pollution, is applicable to packaging and bundling of cable bundles in different parts of an automobile body, particularly can meet the using requirements on high temperature-resistant parts of an engine inside an automobile, and has the long-termtemperature resistance level of 125 DEG C.

Description

Technical field: [0001] The invention relates to a cloth-based adhesive tape made of UV-cured hot-melt pressure-sensitive adhesive for automobile wiring harnesses, including a polyester cloth-based adhesive tape, a non-woven cloth-based adhesive tape and a manufacturing technology thereof. Background technique: [0002] In the field of wrapping and bundling of automotive wiring harnesses, the adhesive tape prepared by using polyester cloth base material and non-woven fabric base material can meet the "Restriction of the Use of Certain Hazardous Substances Directive in Electrical and Electronic Equipment" (ROHS Directive) promulgated by the European Commission. ), and have a good effect on the control of the air quality in the car. At the same time, pressure-sensitive adhesives also play an important role that cannot be ignored in the performance and application of adhesive tapes. [0003] Chinese invention patent ZL 01814153.6 discloses an electrical adhesive tape with non-...
