Problems solved by technology

In 2011, the recycling rate of PET was about 28% in the United States, 50% in Europe, and about 15% to 20% in China, and most of them were in the primary recycling stage, with low technical value
Although there are some examples in the market at present, their physical properties or cost price are difficult to meet the requirements. Therefore, there has been a great call and demand for PET / ABS alloy materials with high impact and low cost.

Abstract

The present invention discloses a high impact recycled PET / ABS alloy composition and a preparation method thereof. The alloy comprises the following components, by weight, 20-50 parts of recycled PET, 5-30 parts of ABS powder, 10-70 parts of ABS, 0-20 parts of PBT, 0.5-10 parts of PET ester exchange master batch, 0.5-5 parts of a compatilizer, 0.1-1 part of an antioxidant, 0.1-1 part of a lubricant, and 0.1-3 parts of a nucleating agent. The preparation method comprises: preparing the materials according to the ratio, placing the materials into a medium speed mixer to mix for 5-30 min to obtain a mixed material, pouring the mixed material into a twin-screw extruder, and carrying out melt extrusion and granulation to obtain the product, wherein a screw rotation speed is controlled to 300-600 rpm. Compared with the high impact recycled PET / ABS alloy composition in the prior art, the PET / ABS alloy material of the present invention has the following characteristics that: the specific ABS content and the self-made ester exchange master batch are adopted so as to improve an impact performance of the PET / ABS alloy.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a high-impact recycled PET / ABS alloy composition and a preparation method thereof. Background technique [0002] Problems such as white pollution, climate warming, and resource shortages have prompted calls for environmentally friendly materials to grow louder and louder. Green and renewable, reducing material carbon emissions has become the development policy of many companies and even many countries. Now there are many requirements and standards for the environmental protection and renewability of materials in the industry, such as RoHS, WEEE, EuP, EPEAT and so on. Based on the above background, the use of green renewable materials will become a future trend. [0003] According to reports, the global PET packaging consumption in 2015 will exceed 14.5 million tons. And the average annual compound growth rate in the Asia-Pacific region is expected to reach 7.4%, while the aver...
