Problems solved by technology

However, if the adhesive tape in the prior art is used for bonding, it can only be forcibly peeled off from the front, which can easily cause damage to parts and may have residual glue to pollute the surface; and if the bonding strength of the tape is reduced, it may cause bonding Objects loosen and fall off during use

preparation example Construction

[0046] The present invention also provides a method for preparing the adhesive layer described in the above technical solution, comprising the following steps:

[0047] a) mixing a thermoplastic elastomer and a reinforcing agent in a solvent to obtain a mixed solution; the thermoplastic elastomer is selected from the group consisting of styrene block copolymer, polyolefin block copolymer, acrylic block copolymer, polyisobutylene, thermoplastic polyurethane One or more of butyl rubber and EPDM rubber; the reinforcing agent is selected from polystyrene, polyphenylene ether, polyethylene terephthalate and polybutylene terephthalate one or more of esters;

[0048] b) sequentially adding tackifying resin, softener, antioxidant and filler to the mixed solution obtained in step a) for mixing to obtain an adhesive dispersion;

[0049] c) coating the adhesive dispersion obtained in step b) on a release film and drying to obtain an adhesive layer.

[0050] In the present invention, fi...

Embodiment 1

[0068] The substrate-free tape provided in Example 1 is composed of an adhesive layer with a thickness of 150 μm and a heavy release film and a light release film attached to the upper and lower sides of the adhesive layer respectively; The release force ratio of the heavy release film is 1:3.

[0069] The adhesive layer is prepared from raw materials comprising the following components: 40 parts by weight of styrene-butadiene-styrene block copolymer (SBS), 40 parts by weight of terpene resin, 15 parts by weight of polystyrene, 20 parts by weight of naphthenic oil, 0.5 parts by weight of phenolic antioxidant, and 2 parts by weight of titanium dioxide.

Abstract

The invention provides an adhesion layer for an adhesive tape. The adhesion layer is prepared from the following raw materials in parts by weight: 40 to 60 parts of a thermoplastic elastomer, 40 to 60parts of tackifying resin, 10 to 20 parts of a reinforcing agent, 10 to 25 parts of a softening agent, 0.2 to 5 parts of an antioxidant and 0.1 to 5 parts of filler, wherein the thermoplastic elastomer is selected from one or more of a styrene block copolymer, a polyolefin block copolymer, an acrylic block copolymer, polyisobutene, thermoplastic polyurethane, butyl rubber and ethylene propylene diene monomer; the reinforcing agent is selected from one or more of polystyrene, polyphenylene ether, polyethylene glycol terephthalate and polybutylene terephthalate. According to the adhesion layerprovided by the invention, the components with specific content are adopted to realize a good compatible effect; the cohesion force is improved on the basis that the adhesion layer has high-elasticityplasticity, so that the adhesion layer has the properties of high peeling force, high temperature resistance, tension without breaking and no removal of residual glue.

Description

technical field [0001] The invention relates to the technical field of adhesive tape production, and more specifically, relates to an adhesive layer used for an adhesive tape and a preparation method and application thereof. Background technique [0002] Adhesive tape is a pressure-sensitive adhesive tape that can bond objects. It is widely used in daily life and industrial fields, and plays the role of fixing, bonding, and protecting. In order to ensure the stability and durability of the bonding, most of the tapes on the market are substrate tapes with high bonding strength. The tape is usually based on paper, cloth, plastic film, metal foil, etc., pressed The sensitive adhesive is evenly coated on the above-mentioned substrate to make a roll-shaped adhesive tape, which is composed of three parts: the substrate, the adhesive and the release film (paper). [0003] At present, in many application scenarios, such as the fixing of components such as batteries and display scre...
