Abstract

The invention discloses a pollution-resistant PC / PET alloy and a preparation method thereof. The alloy comprises the following components and parts by weight: PC: 40-80 parts, PET: 10-40 parts, and pollution-resistant PET masterbatch: 0.1-15 parts parts, compatibilizer: 0.5-3 parts, toughening agent 2-15 parts, antioxidant 0.1-1 part, lubricant 0.1-1 part; prepare materials according to the above components and parts by weight, and then mix the above-mentioned decontamination-resistant PET The materials other than the masterbatch are placed in a medium-speed mixer and mixed for 5-30 minutes to obtain a mixed material. Finally, the mixed material is put into a twin-screw extruder, and the screw speed is controlled at 180-600rpm. The stain-resistant PET master The pellets are fed from the side, melted and extruded, and pelletized to obtain the product. Compared with the prior art, the PC / PET alloy provided by the invention has higher surface hydrophobicity and stain resistance while maintaining better processability.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a stain-resistant PC / PET alloy and a preparation method thereof. Background technique [0002] PC / PET alloy is a semi-crystalline engineering plastic with excellent impact strength, heat resistance, oil and solvent resistance, etc. It is widely used in automobiles, electronics, home appliances and other fields. [0003] Through the retrieval of existing patent documents, it was found that Guo Bin described in the CN 101007893 patent that PC / PET alloy products were obtained by mixing PC pellets, PET slices and additives through mixing and then die molding, for use in Electrical switch film, automobile instrument panel, etc. [0004] Hao Jianxin et al. described in the CN 101712794 patent that the low-temperature toughness of PC / PET alloys can be improved by using MBS and silicon-based toughening agents. [0005] Yu Peng et al. described in CN 101570627 the preparation of a trans...
