TPU/TPE composite modified material

Abstract

The invention discloses a TPU / TPE composite modified material, which comprises: a polymer, polyurethane, a compatibilizer, a laser carving auxiliary agent and processing oil according to a certain weight part ratio, and is specifically prepared from the following raw materials by weight: 50-100% of SEBS, 50-100% of TPU, 30-50% of processing oil, 8-15% of MAH-G-SEBS, 8-15% of NH2-G-SEBS, 0.5-2% ofa laser engraving auxiliary agent, 0.1-0.5% of an antioxidant, 0.1-0.5% of an anti-ultraviolet absorber, 0.5-2% of an antibacterial agent, and 0.5-5% of organic silicone. According to the present invention, the obtained TPU / TPE composite modified material has strong adhesion with ABS, PC, POM, ASA, AS, SAN and other materials, can be subjected to secondary molding injection, can be recycled, meetsthe FDA food hygiene requirements, and further has advantages of no toxicity, no odor, excellent elasticity, high unit weight utilization rate, wide hardness range and easy processing.

Description

technical field [0001] The invention relates to a modified material, in particular to a composite modified material specially used for packaging sheets of electronic products, and belongs to the technical field of electronic product packaging applications. Background technique [0002] At present, there are many kinds of packaging materials for electronic products on the market. Most of them are made of hard polymer materials into plates or sheets, and then made by blistering. During the turnover in the factory or during the transportation of the market, due to the electronic products It is placed in the protective box of hard sheet or plate blister, which will inevitably cause sliding or collision, causing damage to electronic products. At the same time, the surface of the sheet has good antistatic performance, which reduces the electrostatic hazard caused during transportation. The packaging material made of the composite structure of TPU and ABS or the composite structure...
