Abstract

The invention discloses a high-gloss and high-impact resistance PS / PP composite for manufacturing a telephone case and a preparation method thereof. The composite is mainly prepared by the following raw materials by weight portion: 100 portions of PS resin, 20-60 portions of PP resin, 5-15 portions of compatilizer, 3-30 portions of flexibilizer, 0.1-0.9 portion of nucleator and 0.1-0.9 portion of antioxidant. The PS raw material and the PP raw material are fused together by the special compatilizer. The prepared composite has the high-gloss and high-impact resistance features and excellent physical and mechanical properties, and can be used for replacing ABS to manufacture the telephone case. The composite has the characteristics of simple preparation technology, stable size, high gloss, high impact resistance, low cost, and the like.

Description

technical field [0001] The invention relates to a material for manufacturing a telephone casing and a preparation method thereof, in particular to a PS / PP composite material with high surface gloss and high impact resistance and a preparation method thereof. Background technique [0002] Polystyrene (PS) and polypropylene (PP) are one of the five general-purpose plastics. PS is colorless, odorless, easy to color, rigid, non-toxic, no fungus growth, easy to process, good dimensional stability, low hygroscopicity, and good radiation resistance. But its disadvantages are poor heat resistance, intolerance to boiling water, brittleness, low impact strength, and the products are prone to self-cracking due to internal stress. [0003] PP is the only general-purpose plastic that can be boiled in water. It has excellent chemical stability, outstanding ductility, bending fatigue resistance, easy processing, and low production cost. However, the disadvantages of PP are the disadvanta...
