High-glossiness heat-resistant ABS/PET (acrylonitrile-butadiene-styrene/polyethylene terephthalate) bottle chip composite material and preparation method thereof

Abstract

The invention relates to a high-glossiness heat-resistant ABS / PET (acrylonitrile-butadiene-styrene / polyethylene terephthalate) bottle chip composite material. The composite material is composed of the following substances in parts by weight: 100 parts of ABS resin, 10-20 parts of ABS high rubber powder, 20-40 parts of PET bottle chip, 2-20 parts of compatilizer, 5-25 parts of heat-resistance modifier, 0.1-1 part of antioxidant and 0.1-1 part of lubricant. The method widens the high-added-value reutilization range of the recovered PET bottle chips, saves the limited resources, lowers the cost of the ABS composite material, has the advantages of low carbon and environment friendliness, enhances the surface glossiness and heat resistance of the ABS composite material, and widens the application range of the ABS composite material.

Description

technical field [0001] The invention relates to a polymer compound composition, in particular to a high-gloss heat-resistant ABS / PET bottle flake composite material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET), because of its excellent chemical and physical properties and low price, is not only widely used in fiber production, but also used in a large amount in beverage bottle production. However, the wide application of PET in the field of edible liquid flexible packaging has brought about the recycling of a large number of waste PET beverage bottles. With the gradual increase in the amount of PET, the amount of PET bottle recycling is also gradually increasing. According to statistics, the average recycling rate of PET bottle flakes is 20.4%. Countries with high recycling rates such as Switzerland, Germany and Japan are 100%, 49% and 46% respectively, while my country is only 1.7%. At present, most of the recycled PET b...

Problems solved by technology

[0003] With the rapid development of the home appliance industry and the continuous improvement of people's consumption requirements, in some application fields, injection molded products are required not only to have excellent impact toughness, but also to have extremely high surface gloss, for example: for flat-panel LCD TVs For products such as frames, bases, laptop casings, and audio casings, the conventional single ABS resin system is difficult to meet the above requirements, so people have developed high-gloss ABS, such as patents CN102532788A, CN101531801A, etc., using ABS and PET or PMMA, etc. Blending to improve the surface gloss of ABS, but in order to improve the gloss while maintaining the toughness of ABS, it is usually necessary to add a certain amount of toughening agent, but this will inevitably reduce the heat resistance of tough high-gloss ABS alloy resin Sex, and heat resistance is often a very important indicator in the application of ABS alloy resin system

Usually, the heat-resistant agent added to improve the poor heat resistance of the ABS alloy resin system often leads to a decrease in the toughness of the composite material; other components added to improve its gloss often lead to a decrease in the toughness of the composite material. Decrease, heat resistance can not be improved
