Abstract

The invention discloses an HIPS (High Impact Polystyrene) composite material and a preparation method thereof. The HIPS composite material comprises the following components in percentage by weight: 72.6%-94.4% of HIPS, 3%-15% of glass fibers, 0.1%-0.3% of white oil, 2%-10% of a compatilizer, 0.2%-0.6% of an antioxidant and 0.3%-1.5% of a lubricant. The HIPS composite material takes the HIPS as a base body; the mechanical strength of the HIPS material is improved by adding the glass fibers into the HIPS; the linear expansion coefficient is reduced; the synergistic effect of the lubricant and the compatilizer not only can improve a two-phase separation state of the HIPS, but also promotes the compatible dispersion of all the components, so as to form a stable structure; and the luster performance is improved and the surface effect is good.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a HIPS composite material and a preparation method thereof. Background technique [0002] High impact polystyrene resin (High impact polystyrene, referred to as HIPS) is an amorphous thermoplastic resin produced by adding micron-sized polybutadiene (PB) rubber particles to polystyrene (PS), which has good Mechanical properties, but because HIPS contains 5% to 15% rubber, its fluidity will be affected during processing, and PB rubber is incompatible with PS resin, so in HIPS, butadiene and styrene segments are aggregated separately, presents a state of phase separation. In addition, the gloss performance of HIPS material is poor, and its physical and mechanical strength is low, and it shows a large shrinkage at low temperature, and the linear expansion coefficient is too large. The parts are squeezed against each other, causing the product to be easily cracked, thus li...
