Nonwoven fabric base gluing tapes and method for producing the same

Abstract

The invention relates to a non-woven fabric based adhesive tape and a producing method thereof. The adhesive tape is produced by directly spread-coating a thermoplastic elastomer hot-melt pressure-sensitive adhesive on terylene and nylon non-woven fabric substrates by a common hot melt coating machine. The thermoplastic elastomer hot-melt pressure-sensitive adhesive is prepared by heating and blending a block copolymer thermoplastic elastomer and auxiliary agents such as tackifying resin, softening agent, age inhibitor, filler, crosslinking agent,and colorant according to certain proportion. The non-woven fabric based adhesive tape has the advantages that the non-woven fabric based adhesive tape has good mechanical property and adhesion performance, better temperature stability, wear resistance, and noise absorption performance, and good manual tear-out performance, also has simple and convenient production process, no environmental pollution, and lower cost, and is suitable for the covering and binding of cable bundles, in particular for the covering and binding of cable bundles in automotive bodies.

Description

Technical field: [0001] The invention relates to a non-woven fabric-based adhesive tape, in particular to a non-woven fabric-based adhesive tape for wrapping and bundling cable bundles and a manufacturing method thereof. Background technique: [0002] In addition to the pressure-sensitive adhesive properties endowed by the pressure-sensitive adhesive, the performance of the adhesive tape is determined by the inherent properties of the substrate. For example, soft polyvinyl chloride (SPVC) film is a tough film with high elongation and high tensile strength. It is suitable for making adhesive tapes, especially for making electrical adhesive tapes for wrapping and bundling cable bundles. material. However, due to the low softening point of SPVC, the performance of temperature stability, abrasion resistance and environmental noise absorption is poor, which limits its use as an electrical adhesive tape. SPVC begins to decompose a small amount of hydrogen chloride gas when the t...
