Abstract

The invention discloses a thermoplastic elastomer for encapsulating PC / ABS, and a preparation method thereof, wherein the thermoplastic elastomer is prepared from the following components by weight: 20-70 parts of HSBC, 5-30 parts of a compatibilizer, 5-30 parts of a polar elastic component, 5-20 parts of LDPE or PE, 5-20 parts of SBS or SIS, 1-30 parts of white oil, 1-6 parts of an antioxidant, 1-6 parts of an anti-ultraviolet agent, 1-6 parts of a slipping agent, and 1-7 parts of a filler. According to the invention, by adding MAH-PE / PP / POE and MAH-PS as the compatilizers, the phase separation between the non-polar phase and the polar phase in TPE is reduced so as to achieve the effect of mutual dissolution; the polarity-polarity interaction with the PC / ABS base material can be generatedby utilizing the polarity; and by adding the unhydrogenated SBS or SIS, the adhesive force of the TPE is increased to improve the bonding between the soft rubber and the hard rubber.

Description

technical field [0001] The invention relates to a thermoplastic elastomer used for encapsulating PC / ABS and a preparation method thereof. Background technique [0002] Thermoplastic elastomer encapsulation is to coat soft rubber (thermoplastic elastomer material or TPE for short) to hard rubber (engineering plastics, usually PE, PP, PC, PET or PBT, PA, etc.). The main purpose of lagging is to increase aesthetics, improve tactility, enhance hand feeling, provide shock absorption, enhance grip, prevent slipping, block gas or liquid, connect different parts, etc. The processing methods generally used are: (1) two-color injection molding, one-time molding; (2) overmolding, two-time injection molding, and coating on the engineering plastic substrate. Mainly used in medical equipment handles, electric tool handles, wearable devices, automotive interiors, fast-moving consumer products, household appliances accessories, wires and cables, medical food packaging and other application...
