Embodiment 1

[0044] 1. Make cardboard honeycomb model

[0045] Different forms of honeycomb models are made of PP (polypropylene). The honeycomb models have a honeycomb-shaped and hollow cavity. The cavity of the model can have different honeycomb shapes, including but not limited to hexagonal honeycomb models. . The thinnest wall thickness of the honeycomb model can reach 0.5mm. In addition, the honeycomb pattern is closed on one side and open on the other, allowing it to be filled with polystyrene pellets in a subsequent step.

[0046] 2. Make the shape of polystyrene foam plastic by extrusion method.

[0047] Fill the polystyrene (PS) pellets into the hollow cavity of the polypropylene (PP) honeycomb model, seal both sides of the model, place it in steam and heat it until the foaming is complete, and release the mold to obtain a honeycomb polystyrene plastic shape .

[0048] 3. Brush paint on the polystyrene plastic pattern

[0049] Brush the paint on the surface of the polystyrene...

Abstract

The invention provides a honeycomb metal, a preparation method thereof and an automobile containing the honeycomb metal, wherein the honeycomb metal is integrally formed. The honeycomb metal has good integrity and high strength, does not need to be formed by bonding, and effectively overcomes the problems of low connection strength and processing at the bonding position of the existing honeycomb metal.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a honeycomb metal, a preparation method thereof and an automobile containing the same. Background technique [0002] Metal honeycomb panels have a series of advantages such as light weight, high strength, high rigidity, and excellent heat and sound insulation performance. Magnesium alloys have low density, and have very obvious advantages such as good specific stiffness, specific strength, and recyclability. It plays an important role in the weight of components and has very broad application prospects. The outer skin of the car, the body structure, the frame structure, the bumper, the seat, the door, etc. are all feasible application parts. [0003] At present, the preparation methods of magnesium alloy honeycomb core mainly include: expansion method, pressure bonding forming method, pressure brazing forming method, stretching method and so on. The pressure bonding forming...
