Energy-absorbing foam aluminum material for manufacturing vehicle bumper

Abstract

The invention discloses an energy-absorbing foam aluminum material for manufacturing a vehicle bumper. The material is characterized by being prepared by the following components in parts by weight: 100 parts of aluminum powder, 5 parts of tungstate, 5 parts of silicon carbide, 2 parts of iron ore powder, 1 part of silicotungstic acid, 0.5 part of magnesium oxide, and 0.5 part of modified foaming agent. The material is simple in preparation method, excellent in product effect, low in cost of the foaming agent and economical and effective, reduces traditional preparation steps, and reduces the production cost; and the porosity of foam aluminum is increased through dual functions of thickening and foaming of the foaming agent.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an energy-absorbing aluminum foam material used for manufacturing vehicle bumpers. Background technique [0002] At the end of the 20th century, energy issues and environmental protection issues became two hot issues, which attracted increasing attention from all over the world. Facing the increasing shortage of conventional energy and the increasingly serious environmental pollution, the automobile industry, one of the main carriers of the two issues, began to do Make positive strategic adjustments to deal with the adverse effects of these problems. Research and development of energy-saving vehicles has become the theme of the development of the automotive industry. People have begun to pay attention to the issue of lightweight vehicles, because vehicles with smaller masses require relatively less energy, which can reduce environmental pollution while reducing emissio...
