Abstract

The invention relates to a novel environment-friendly, temperature-resistant and wear-resistant cloth-based adhesive tape manufactured with ultraviolet (UV) curable hot-melt pressure-sensitive adhesive, and a manufacturing technology thereof. According to the pressure-sensitive adhesive tape, a novel UV-curable hot-melt pressure-sensitive adhesive is directly spread on a terylene fabric or nonwoven fabric substrate with a hot-melt coating machine equipped with a UV lamp; and the pressure-sensitive adhesive is subjected to crosslinking curing under UV irradiation, such that the adhesive tape is obtained. The UV-curable hot-melt pressure-sensitive adhesive is obtained by heating and blending certain proportions of a block copolymer thermoplastic elastomer, tackifying resin, a softener, an olefinic monomer containing long-chain alkyl, and auxiliary agents such as a photo-initiator and an antioxidant. The cloth-based adhesive tape has excellent mechanical performance, adhesive performance, high-temperature resistance and wear resistance. The adhesive tape also has the advantages of low hot-melt coating temperature, simple manufacturing process, and no environment pollution. The adhesive tape is suitable for coating and bundling cable bundles at different parts in an automotive body. The adhesive tape can especially satisfy application requirements at high-temperature resistant parts at the engine inside the automotive. A long-term temperature resistance grade of the adhesive tape reaches 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-...
