Novel double-sided adhesive tape

Abstract

The invention provides a novel double-sided adhesive tape, which comprises a first acrylic adhesive layer, a non-woven fabric, a second acrylic adhesive layer and double-plastic PE coated paper. The first acrylic adhesive layer, the non-woven fabric, the second acrylic adhesive layer and the double-plastic PE coated paper are glued in order. The non-woven fabric is fixedly bonded to the first acrylic adhesive layer and the second acrylic adhesive layer respectively, and the second acrylic adhesive layer is detachably bonded to an inner side of the double-plastic PE coated paper. The novel double-sided adhesive tape provided by the invention has the advantages of convenient use, strong double-side initial adhesion and persistent adhesivity, high peeling strength, good water resistance, excellent high temperature and humidity resistance, safety and environmental protection, and is especially suitable for the electronic market and home furnishing market.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to a novel double-sided adhesive tape. Background technique [0002] Double-sided adhesive tape is a roll-shaped adhesive tape made of paper, cloth, and plastic film as the base material, and then uniformly coated with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above-mentioned base material. , adhesive, and release paper are composed of three parts. Double-sided tape is widely used in leather, stickers, stationery, office, electronics, car trim fixing, shoe industry, handicraft pasting and positioning, etc. [0003] At present, due to the unreasonable preparation of raw materials and the large amount of cheap raw materials used in the double-sided tapes used in the electronics market and the home market, the performance of the double-sided tapes is average and the quality of use is not high. The main problems are: 1) The initi...

Problems solved by technology

[0003] At present, due to the unreasonable preparation of raw materials and the large amount of cheap raw materials used in the double-sided tapes used in the electronics market and the home market, the performance of the double-sided tapes is average and the quality of use is not high. The main problems are: 1) The initial adhesion is not high 1. General stickiness; 2) Low peel strength, easy to stick to the cover when peeling off; 3) Poor water resistance, easy to absorb water, affecting adhesion; 4) General high temperature and high humidity resistance; 5) Chemical corrosion resistance is not strong; 6) Does not meet environmental protection requirements, etc.

In addition, when the commonly used double-sided adhesive tape is used, because the release paper covered on the adhesive layer is too densely adhered, it is not convenient, fast and smooth for people to tear the release paper by hand, and it may even appear that it cannot be torn off. The situation where part of the adhesive tape is wasted due to the type paper, resulting in unnecessary waste
