Problems solved by technology

However, this kind of recycled plastic that has been simply recycled or blended is easy to age and degrade during use, and the performance of the material for producing automobile bumpers is greatly reduced in terms of strength, hardness, impact toughness, heat resistance, and stability; on the other hand , some residual antioxidants in recycled plastics and some low-molecular mixtures formed due to degradation, will appear on the product with different degrees of irritating odor, which greatly limits the scope of use of recycled plastics

Abstract

The invention discloses a recycled material for preparing an automobile bumper. The recycled material is prepared from the following raw materials in percentage by weight: 40-50% of recycled polypropylene, 0.1-1% of an elastomer, 0.1-3% of an inorganic mineral filler, 0.1-3% of diatomite, 0.1-3% of an antioxidant and 40-60% of recycled polyethylene. The recycled material has the characteristics ofbeing low in odor, impact-resistant and high in strength.

Description

technical field [0001] The invention belongs to the technical field of material science, and in particular relates to a recycled material used for preparing automobile bumpers. Background technique [0002] The rapid development of the global plastics industry has brought a huge boost to the world economy, but it has also brought a lot of waste plastics. As a new resource, waste plastics contain huge development and utilization value. The sustainable recycling of waste plastics is the general trend of the development of recycled plastics, which has attracted the attention of countries all over the world. At present, there are many technologies and methods for recycling waste plastics, mainly including sorting and recycling, simple regeneration, compounding, degradation and burning. [0003] The car bumper is a safety device that absorbs and moderates external impact and protects the front and rear of the car body. In the automobile industry, with the rapid development of t...
