Plastic alloy composition, body panel component and vehicle

Abstract

The invention provides a plastic alloy composition. The plastic alloy composition comprises the following raw materials in parts by mass: 100 parts of polypropylene, 15-30 parts of high density polyethylene, 3-20 parts of polysulfone, 10-25 parts of barium sulfate, 1-2 parts of triallyl isocyanurate, 5-15 parts of polystyrene, and 4-8 parts of methyl methacrylate. The plastic alloy composition canbe used for substituting a traditional aluminium alloy material used for a vehicle to prepare a body panel component.

Description

technical field [0001] The invention relates to the field of new materials and automobile manufacturing, in particular to a plastic alloy composition, a body panel part prepared with the plastic alloy composition and a vehicle comprising the body panel part. Background technique [0002] At present, new energy vehicles are still in the development stage. New energy vehicles are powered by batteries or fuel cells. And other supporting public facilities are not as common as traditional gas stations. The current research on new energy vehicles mainly focuses on improving energy supply methods and improving energy supply efficiency, while the main materials of new energy vehicles mostly use traditional metal materials such as aluminum alloys. Studies have shown that the heavier the body of the car, the faster the energy consumption of the car and the relatively more carbon emissions. Because the battery (or fuel cell) of current new energy vehicles can provide energy is limite...

AI Technical Summary

Problems solved by technology

Since the battery (or fuel cell) of new energy vehicles can provide limited energy, and the weight of the car body will limit its voyage, the voyage of new energy vehicles cannot meet people's needs well.

In addition, the large carbon emissions caused by the overweight of the car body is also a key research issue that needs to be improved.

[0003] In addition, using traditional aluminum alloy and other metal materials to manufacture a complete vehicle requires 20,000 parts. Not only does each part need to go through a series of complicated processes such as designing molds-die stamping-molding, etc. Forming, and the assembly process of assembling 20,000 parts into a complete vehicle is extremely complicated and takes a long time

Secondly, in the process of car beauty, the car needs to be painted, which is complicated and causes certain pollution.

Furthermore, once the car is damaged, its maintenance process is also more complicated

In addition, the total production of aluminum alloy materials for automobiles in China is relatively small, and there are factors such as unstable quality, and there is still no stable supply capacity for large automobile factories to provide automobile materials. Import, the price of imported aluminum alloy materials is 60,000 yuan / ton

Due to the high cost of metal materials such as aluminum alloys, the cost of manufacturing the entire car is relatively high

In addition, when the aluminum alloy automobile sheet is made into an automobile part, it needs to go through processes such as cutting and grinding, so there is a certain amount of loss in the manufacturing process.
