Abstract

The invention relates to a transparent impact-resistance polystyrene and a preparation method thereof, particularly a transparent high-impact-resistance polystyrene and a preparation method thereof. The polystyrene comprises the following components in percentage by weight: 25-40% of GPPS (general purpose polystyrene), 50-70% of K gum, 0.5-1% of SMA (styrene maleic anhydride), 5-10% of toughener, 0.2-0.5% of lubricant, 0.1-0.3% of coupling agent and 0.1-0.3% of antioxidant, totaling 100%. The preparation method comprises the following steps: proportionally and uniformly mixing the materials with a high-speed mixer, and extruding and granulating with a double screw extruder. The polystyrene has the advantages of high transparency, favorable product formability, favorable dimensional stability, high bending resistance and high tear resistance.

Description

technical field [0001] The invention relates to the field of thermoplastic materials, in particular to a polystyrene and a preparation method thereof, in particular to a transparent impact-resistant polystyrene and a preparation method thereof. Background technique [0002] Polystyrene (PS) is a resin polymerized from styrene (SM), which is mainly divided into general-purpose polystyrene (GPPS), high-impact polystyrene (HIPS) and expanded polystyrene (EPS). ), is one of the five general-purpose thermoplastic synthetic resins. [0003] General-purpose polystyrene (GPPS) resin is limited due to poor impact resistance and fragile products. Adding rubber to styrene monomer for free radical polymerization can produce chemically grafted high-impact polystyrene (HIPS). However, the opacity of HIPS due to the addition of rubber components makes it more demanding on transparency. High packaging areas are limited. Since the mid-1970s, foreign countries began to develop transparent ...
