Embodiment Construction

[0015] Prepare each component by weight shown in Table 1

[0016] The weight proportion of table 1 embodiment 1~embodiment 3

[0017]

[0018]

[0019] The above-mentioned tackifier is rosin.

[0020] The above-mentioned epoxy resin is a bisphenol A type epoxy resin.

[0021] The preparation method is:

[0022] S1: Natural rubber, styrene-butadiene rubber, neoprene rubber, EPDM rubber, stearic acid, phenolic resin, coumarone resin, epoxy resin, ethylene glycol ether acetate, dioctyl phthalate , dioctyl adipate, N,N'-diphenyl-p-phenylenediamine, N,N,N-tris(polyoxypropylene polyoxyethylene)amine, ethoxylated amine, benzotriazole, hindered amine mixed After uniformity, carry out mastication;

[0023] S2: dissolving the mixture obtained by mastication in a mixture of pine tar, paraffin, ethyl acetate and naphthenic oil;

[0024] S3: Add tackifier and polyvinyl alcohol, stir evenly, and get final product.

Abstract

The invention provides a rubber-type pressure-sensitive adhesive. The rubber-type pressure-sensitive adhesive comprises the following components in part by weight: 10-20 parts of natural rubber, 15-20 parts of styrene-butadiene rubber, 10-15 parts of chloroprene rubber, 3-6 parts of ethylene-propylene-diene monomer, 2-4 parts of stearic acid, 3-5 parts of phenolic resin, 1-2 parts of coumarone resin, 2-4 parts of epoxy resin, 20-30 parts of ethyl acetate, 5-10 parts of glycol ether acetate, 3-6 parts of tackifier, 3-6 parts of dioctyl phthalate, 3-8 parts of hexyldioctyl ester, 10-15 parts of polyvinyl alcohol, 10-15 parts of paraffin wax, 5-10 parts of pine tar, 5-10 parts of N,N'-diphenyl-p-phenylenediamine, 10-20 parts of naphthenic oil, 2-5 parts of N,N,N-tri (polyoxypropylene polyoxyethylene) amine, 2-3 parts of ethoxylate amine, 1-2 parts of benzotriazole and 1-2 parts of hindered amine. The rubber-type pressure-sensitive adhesive is strong in adhesion and good in durability; and after thermal aging, an adhesion test shows that the adhesion still lasts more than four hours and a release force test shows that the release force lasts more than 7 hours.

Description

technical field [0001] The invention provides a pressure-sensitive adhesive, in particular relates to a rubber-type pressure-sensitive adhesive with good durability, and belongs to the technical field of polymer materials. Background technique [0002] Pressure-sensitive adhesive is a kind of adhesive sensitive to pressure. It is a kind of adhesive that can be firmly bonded to the adherend without the help of solvent, heat or other means, and only needs to apply light finger pressure. Usually, the pressure-sensitive adhesive is applied to substrates such as plastic films, fabrics, paper or metal foils to make pressure-sensitive tapes, pressure-sensitive adhesive labels and other products for use. It has the advantages of being easy to stick, not difficult to remove, and not damaged when peeled off, so it is also called self-adhesive. [0003] Among them, the rubber-type pressure-sensitive adhesive is prepared by dissolving components such as rubber elastic body, tackifier, ...
