Problems solved by technology

The existing processing technology is difficult to solve the compatibility between waste polyester packaging and polymer resin. The processed material is easy to delaminate during the injection molding process, and the surface of the product is peeled. The material has poor toughness and is easy to break. Therefore, it is not possible to obtain excellent recycled materials with performance comparable to new raw materials produced by petrochemical plants

Abstract

The invention belongs to the technical field of high polymer materials and relates to a resin material and a preparation method thereof. The resin material comprises the following components in parts by weight: 10 to 40 parts of crushing material of waste polyester packages, 35 to 80 parts of high polymer resin, 3 to 10 parts of compatilizer, 3 to 15 parts of toughening agent, 0.5 to 1 part of antioxidant aid and 0.2 to 0.5 part of processing aid. The resin material is prepared by using a double-screw extrusion process, the condition that a large amount of polyester is hydrolyzed is avoided in a production process, and the problem that the two main base materials are incompatible is solved. According to the resin material, the performance reaches the performance of the primary novel material which is produced in the petrochemical industry, recovered polyester packages can be converted into a high-quality plastic material, and compared with the method for degrading and drawing the recovered polyester package into short fibers or woven bags, the resin material has good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a resin material and a preparation method thereof. Background technique [0002] Nowadays, polyester packaging is increasingly used in society, such as commonly used mineral water bottles, coke bottles, milk bottles, oil bottles, etc. After we consume these contents, we just throw them away or sell them to some waste recycling stations. The recycling of waste polyester packaging is not a new thing, but over the years many polyester packaging have been simply shredded and then sent to small workshops for downgrading and drawing to make short fibers or woven bags. This low value-added utilization method is extremely The land wastes the potential value of resources, and such processing cannot be recycled. As we all know, polyester is processed and transformed from petroleum. The global consumption of polyester is increasing year by year. At the same time, the amount of waste...
