Abstract

The invention relates to a scratch-resistant PS (Polystyrene) composite material. The scratch-resistant PS composite material is prepared from the following components in parts by weight: 80 to 100 parts of PS, 3 to 5 parts of titanate, 10 to 16 parts of heat-conducting scratch resistant master batches, 0.1 to 0.5 part of an antioxidant and 0.1 to 0.3 part of a compatilizer; and the heat-conducting scratch resistant master batches are prepared from the following components in parts by weight: 40 to 60 parts of LDPE (Low-Density Polyethylene), 12 to 16 parts of TiO2-supported ZnO particles, 0.1to 0.3 part of a coupling agent and 0.1 to 0.5 part of a lubricating agent. The heat-conducting scratch resistant master batches prepared by the application are simple in process and low in cost; andthe addition of the heat-conducting scratch resistant master batches, the heat conducting performance of the PS composite material is improved, and the scratch resistance of the PS composite materialis also improved.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a scratch-resistant PS composite material. Background technique [0002] Polystyrene (PS) has the advantages of light weight, non-toxic, odorless, good chemical stability, insoluble in common solvents at room temperature, and low water absorption. Although the overall performance of PS is excellent, in some special application fields, there are high requirements for thermal conductivity and scratch resistance. Ordinary PS cannot meet this requirement, which greatly limits the application range of PS composite materials. [0003] In view of this reason, the present application has innovatively prepared a PS composite material with excellent thermal conductivity and scratch resistance to make up for the shortcomings of existing PS composite materials. This PS material has not been reported so far. has very important practical significance. Contents of the invention ...
