Problems solved by technology

[0003] my country is a big country that produces and uses PP materials and PET fiber materials. The annual consumption exceeds 10 million tons. The treatment of these wastes requires a huge waste of manpower and material resources. If they can be used reasonably, not only can the pressure on environmental protection be greatly relieved, but also, It can be made into high value-added products and has a wide range of applications. However, the recycling rate of materials in the prior art is low, and the quality of products made from this waste is not high, and it still cannot meet people's needs and environmental protection requirements.

Abstract

The invention discloses a novel application method for an automobile tail door trim bottom felt recovered material, belongs to the technical field of material recovering, and mainly relates to an automobile recovered material application method. In order to solve the problems such as a low material recovery rate and low quality of a product manufactured from the waste in the prior art, the novel application method comprises the following steps of: step I, dividing the recovered materials into two types according to a PP material component and a PET material component; step II, grinding the PET material into micro powder; step III, pulverizing the PP material into particles; and step IV, compounding PP fibers with PET particles, thereby manufacturing a felt body. According to the novel application method, the used raw materials can be waste raw materials produced inside a plant, the material components are controllable, and the technological process is simple.

Description

technical field [0001] The invention relates to an application method of recycled materials for automobiles, which belongs to the technical field of material recycling, and mainly relates to an application method of recycled materials for bottom felts of automobile tailgate trims. Background technique [0002] PP (polypropylene) material, which is an engineering thermoplastic material, combines a series of advantages such as good toughness, high strength, good heat insulation, light texture, corrosion resistance, high elasticity and good hand feeling, and low cost. The most important thing is that PP material is a kind of plastic that can be recycled and reused, which is of great benefit to environmental protection, so it is welcomed by people. At present, the use of PP materials to manufacture automotive interior panels has become the mainstream. The annual production of instrument panels in Europe consumes 120,000 tons of thermoplastic materials, of which PP materials acco...
