Abstract

The invention discloses a high-tenacity transparent PS plastic cement material. The high-tenacity transparent PS plastic cement material consists of the following raw materials in parts by weight: 70-85 parts of polystyrene (PS), 5-8 parts of polyether sulfone resin (PES), 7-12 parts of polyvinylidene fluoride (PVF) and 3-10 parts of a composite modifier. The invention further discloses a preparation method of the high-tenacity transparent PS plastic cement material. According to the preparation method disclosed by the invention, the PES, the PVF and the PS are blended so as to obtain the plastic cement material, a shock resistant modifier and a flexibilizer in the composite modifier are used for composite modification for the plastic cement material, so that the rigidity and the tenacity of PS products are effectively balanced, and the PS plastic cement material with high tenacity, high impact strength and favorable transparency is obtained.
