AI Technical Summary

Problems solved by technology

The improvement of surface properties mainly depends on the PET component, but the increase of the PET component will cause the toughness of the alloy material to be poor. At the same time, the surface scratch resistance of the traditional ABS / PET alloy material is average, which cannot meet the higher requirements of the product.

Abstract

The invention provides a toughened scratch-resistant ABS / PET alloy and a preparation method thereof. The toughened scratch-resistant ABS / PET alloy is prepared from, by weight, 65-85 parts of ABS resin, 15-30 parts of PET resin, 0-6 parts of a scratch-resistant modifier, 0-8 parts of a toughening modifier, 0-5 parts of a compatilizer, 0-0.5 part of an antioxidant, 0-1 part of a lubricating dispersant and 0-2 parts of a filler. The toughened scratch-resistant ABS / PET alloy is simple in processing technology, low in production cost and simple in application mode; a forming processing technology of the toughened scratch-resistant ABS / PET alloy is the same with that a common ABS / polyester alloy material; and silicone rubber and silicone are synchronously adopted to improve the performance of the ABS / PET alloy. Compared with a traditional ABS / PET alloy material, the ABS / PET alloy material is excellent in toughness and surface scratch resistance, the application range of the ABS / PET alloy material is greatly expanded, and the ABS / PET alloy material can also be used for recycling mineral water bottle PET materials and is beneficial to cyclic economy.

Description

technical field [0001] The invention belongs to the technical field of modified plastics, and relates to a toughened and scratch-resistant ABS / PET alloy and a preparation method thereof. Background technique [0002] At present, there are many blended alloy materials of ABS and PMMA in my country, mainly based on ABS and supplemented by PET. Compared with pure ABS resin, ABS / PET alloy material has better surface gloss and strength, and its chemical cracking resistance is significantly improved, but the toughness attenuates significantly with the increase of PET content. ABS / PET alloy materials are mainly used as exterior materials for external casings of electronics, home appliances and other equipment. In addition to satisfying the basic mechanical properties, the surface properties of the molded parts are very critical, such as surface hardness, gloss, scratch resistance, etc. The improvement of surface properties mainly depends on the PET component, but the increase of ...
