Abstract

The present invention relates to a thermoplastic elastomer composition for bonding ABS and a preparation method thereof. The composition is prepared by raw materials with the following weight proportion: 40 to 70 percents of polyurethane (TPU), 5 to 20 percents of SEBS, 10 to 30 percents of extending oil, 2 to 5 percents of SEBS-g-MAH, 0 to 30 percents of active calcium carbonate and 0.1 to 0.5 percent of antioxidant. The preparation method comprises the following steps of: weighting the raw materials according to weight proportion, mixing SEBS and white oil evenly in high mixing machine, then adding other raw materials and mixing for 2 to 5 minutes, discharging; putting the raw materials mixed evenly into an extruser for prilling. The invention has the characters that the prepared thermoplastic elastomer not only has good bonding property with ABS and PC, but also has adjustable hardness according to the client requirements, and can be used for producing handle sheath, cushion pad, and the like.

Description

technical field [0001] The invention relates to a thermoplastic elastomer composition for bonding ABS and a preparation method thereof. The material has excellent bonding performance with ABS and PC, can be directly injected, and belongs to the technical field of thermoplastic elastomers. Background technique [0002] With the continuous improvement of people's product requirements, the demand for TPE modified materials that can be used to bond ABS and PC continues to increase. This kind of TPE is mainly used in the fields of handle coating materials and sheath materials. At present, the TPE modified materials that can be used to bond ABS and PC on the market mainly have the disadvantages of weak adhesion and high price. The adhesive prepared by this method not only has high bonding strength, but also is relatively cheap, and has Great market potential. Contents of the invention [0003] The purpose of the present invention is to provide a thermoplastic elastomer composit...
