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 relates to the technical field of plastic materials, especially to a high-elasticity plastic material. The high-elasticity plastic material is prepared from the following ingredients (by weight): 35-36.5% of SEBS, 16-20% of paraffin oil, 1.53-1.63% of silicone oil, 10-12% of PP, 6.3-7.3% of EPDM, 4.5-5.2% of POE, 3.3-3.7% of PE, 8-8.8% of TPV, 9.3-10.2% of calcium carbonate, 0.03-0.07% of erucic acid, 0.01-0.02% of a stabilizing agent 1, 0.015-0.025% of a stabilizer, and 0.013-0.017% of a stabilizing agent 2. By filling PP / extending oil / SEBS blends with a toughening filling material, the plastic material has excellent toughness. After mixed with paraffin oil, a synergistic effect can be achieved and the high-elasticity plastic material is endowed with excellent elasticity.

Description

technical field [0001] The invention relates to the technical field of plastic materials, in particular to a highly elastic bonding plastic material. 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 fixed on the double-sided adh...
