Abstract

The invention discloses an adhesive for sticking high-oil-filling SEBS (Styrene-ethylene / butylene-styrene) and a preparation method thereof. The adhesive for sticking the high-oil-filling SEBS, disclosed by the invention, is prepared from the following components in parts by weight: 75 to 90 parts of the SEBS, 5 to 10 parts of an acrylate monomer, 0.1 to 0.3 part of an initiator, 4 to 15 parts of tackifying resin and 200 to 400 parts of a mixed solvent. According to the adhesive for sticking the high-oil-filling SEBS, disclosed by the invention, an initial sticking and rapid positioning property of the adhesive is improved through introducing the tackifying resin to an acrylate grafted modified SEBS polymer solution and a stable effect of sticking performance can be realized.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an adhesive used for bonding highly oil-extended SEBS and a preparation method thereof. Background technique [0002] SEBS materials have high oil-filling and oil-retaining properties. Highly oil-filling SEBS is soft, high-strength, and feels good. It is often used as a raw material for adult products. Due to the aliphatic oil precipitated on the surface, it is difficult to quickly locate and bond together highly oil-extended SEBS materials. Adhesives for bonding highly oil-extended SEBS materials are lacking in the prior art. Contents of the invention [0003] Based on the status quo of the above-mentioned prior art, the research content is the adhesive used for bonding high oil-filled SEBS parts, aiming to solve the problem of difficult bonding between high oil-filled SEBS parts, and to achieve fast initial adhesion of parts during use. Positioning, after complete curing, t...
