Plastic alloy composition, vehicle structure enhancing part and vehicle

Abstract

The invention provides a plastic alloy composition. The plastic alloy composition is prepared from the following raw material components in parts by mass: 100 parts of polypropylene, 10 to 25 parts ofhigh density polyethylene, 5 to 25 parts of polysulfone, 15 to 30 parts of barium sulfate, 0.994 to 3 parts of triallyl isocyanurate, 5 to 15 parts of polymethyl methacrylate and 0.003 to 0.01 part of graphene. The plastic alloy composition provided by the invention can be used for replacing a traditional aluminum alloy material for an automobile to prepare a vehicle structure enhancing part.

Description

technical field [0001] The invention relates to the fields of new materials and automobile manufacturing, in particular to a plastic alloy composition, a vehicle structure reinforcement part prepared by using the plastic alloy composition, and a vehicle comprising the vehicle structure reinforcement 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 are mostly traditional metal materials such as aluminum alloys. Studies have shown that the heavier the body of the car, the faster the car consumes energy and the relatively more carbon emissions. Because the battery (or fuel cell) of the current new en...

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 range, the range 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 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 alloy, the cost of manufacturing the entire car is relatively high

In addition, aluminum alloy automotive materials need to go through cutting, grinding and other processes when they are made into auto parts, so there is a certain amount of loss in the manufacturing process.
