Polystyrene high-gloss toughening color master batch and preparation method thereof

Abstract

The invention discloses a polystyrene high-gloss toughening color master batch and a preparation method thereof. The color master batch comprises the following raw materials according to parts by weight: 15-55 parts of polystyrene, 10-35 parts of pigments, 5-20 parts of toughening agent, and 5-20 parts of brightener. The preparation method comprises the following steps of: 1) adding the pigments, a coupling agent, a surface active agent and the brightener into a high-speed mixer according to the raw materials ratio and mixing uniformly; 2) then adding polystyrene and the toughening agent into the high-speed mixer according to the raw material ratio and evenly mixing with the mixed material obtained in step 1); and 3) adding the mixed material obtained in step 2) into a twin-screw extruder for mixing and extruding, cooling, grain-sized dicing and drying to obtain the polystyrene high-gloss toughening color master batch. The color master batch disclosed by the invention not only has the effect of dyeing, but also can significantly improve the toughness and surface glossiness of polystyrene recycled materials, expand the application range of the polystyrene recycled materials, and achieve the purposes of environmental protection and energy conservation.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a polystyrene high-gloss toughened color masterbatch and a preparation method thereof. Background technique [0002] Polystyrene (PS) is a general-purpose plastic with a wide range of uses. It has the characteristics of low price, excellent comprehensive performance, and easy processing and molding. The recovery and reuse of PS is a hot research topic at present. However, after repeated thermal processing of polystyrene, the molecular chain is broken and the average molecular weight is reduced. Therefore, when recycled polystyrene materials are processed into products, they have disadvantages such as poor toughness and lack of luster, which limits the recovery of polystyrene. The field of application of the material. Contents of the invention [0003] In view of this, the present invention provides a polystyrene high-gloss and toughened color masterbatch and a preparation met...
