Problems solved by technology

[0005] However, when this thermoplastic elastomer is bonded to the surface of the core tube, due to the strong bonding force, when the thermoplastic elastomer is to be replaced, the thermoplastic elastomer and the core tube need to be replaced at the same time, resulting in difficulty in replacement.

Abstract

The invention discloses a TPE-base composite film material. The TPE-base composite film material comprises, by weight, 100-120 parts of SEBS, 40-80 parts of PP, 10-30 parts of toughening material, 10-20 parts of cellulose-type adhesive, 3-10 parts of compound stabilizer, 10-30 parts of extending oil, 5-10 parts of paraffin lubricant and 1-2 parts of antioxidant. A TPE-base composite film prepared according to the formula is excellent in elastomeric performance, good in adsorption capacity for rolling core pipes and high in fit performance and can be used for being attached to buffer layers of some high-precision optical films to guarantee that the high-precision optical films are free of creases when wound on the TPE-base composite film.

Description

technical field [0001] The invention relates to the field of film materials for roll core tubes, in particular to a TPE-based composite film material and a preparation method. Background technique [0002] Most of the materials used in the core tube are polyamide (PA), polycarbonate (PC), polyethylene terephthalate (PET), polyphenylene ether (PPO) and ABS resin. These materials belong to Engineering resin, with excellent impact resistance, high rigidity, dimensional stability and small molding shrinkage, has been widely used in life and production. However, most engineering resins are made of hard materials, and the surface of the prepared core tube is very hard and smooth. When the coil is wound with the core tube, it is difficult to fit tightly with the core tube, and the coil cannot be rolled smoothly. around this material. [0003] In order to solve the above technical problems, double-sided adhesive tape is attached to the surface of the core tube, and the coil is fix...
