Problems solved by technology

However, recycled plastics have disadvantages such as low strength, no toughness, low gloss, and poor thermal stability. In addition, some residual additives in recycled plastics and some low-molecular mixtures formed due to degradation will appear on the product to varying degrees. Pungent odor, which greatly limits the scope of use of recycled plastics

Abstract

The invention discloses a high-tenacity composite regenerated plastic, which is prepared from the following raw materials in parts by weight: 100 parts of waste plastic, 10-16 parts of calcium borate, 30-50 parts of a filler, 0.5-1.5 parts of an antioxidant, 10-30 parts of a flexibilizer, 3-6 parts of N,N'-methylene bisacrylamide and 6-10 parts of an enhancer. The invention further discloses a preparation method of the composite regenerated plastic. By adopting the waste plastic as the raw material, economic recovery and utilization of solid wastes are achieved, meanwhile, the prepared composite regenerated plastic can be repeatedly recovered, regenerated and reused, and no environmental pollution is caused. Through synergistic effect of multiple raw materials, the compatibility and the dispersity of the raw materials are improved, meanwhile, the strength and the tenacity of the composite regenerated plastic are significantly improved, the high-tenacity composite regenerated plastic is free of peculiar smell, low in toxicity and environment-friendly, and the service life is prolonged, thereby reducing the production cost and the use cost.

Description

technical field [0001] The invention belongs to the field of composite materials, and in particular relates to a high-toughness composite recycled plastic and a preparation method thereof. Background technique [0002] During the development of nearly a hundred years, plastics and plastic products have brought great contributions and infinite convenience to human production and life, but as time goes by, some plastic products are seriously polluted by plastic waste after their life cycle ends. The environment has become an increasingly serious problem. Ma Zhanfeng, deputy secretary-general of China Plastics Processing Industry Association and secretary-general of the Special Committee on Plastic Recycling, also believes that landfilling is not the best way to deal with waste plastics. He said: "The small weight and large volume of plastics in garbage determine its Its final disposal is not suitable for landfill, but it is a macromolecular material with a high calorific value...
