Anti-collision material and method for preparing anti-collision bumper by applying anti-collision material

Abstract

The invention relates to the technical field of new materials, in particular to an anti-collision material and a method for preparing an anti-collision bumper by applying the anti-collision material.The anti-collision material is prepared from, by weight, 100 parts of aluminium powder, 5 parts of tungstate, 5 parts of silicon carbide, 2 parts of iron ore powder, 1 part of silicotungstic acid, 0.5part of magnesium carbide, 0.5 part of a modified foaming agent, 2 parts of tungsten carbide, 3 parts of tantalum carbide, 2 parts of niobium carbide, 1 part of purple grit mud, 0.5 part of potassiumsilicate and 0.5 part of boron nitride. The anti-collision material is reasonable in component preparation and low in cost, the traditional preparation steps are reduced, the production cost is lowered, the foaming agent has the dual functions of thickening and foaming, the porosity of the material is increased, and the energy absorption effect is improved.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to an anti-collision material and a method for preparing an anti-collision bumper using the same. 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 Active strategic adjustments were made 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, and people have begun to pay attention to the issue of lightweight vehicles, because vehicles with smaller masses require relatively less energy , While reducing emissions, it can also reduce env...

Problems solved by technology

Although the hollow metal tubes currently used as energy-absorbing structural parts for automobile bumpers have high strength, their energy absorption is not as good as that of foamed aluminum. Stand alone as an energy-absorbing structural member

Therefore, if the hollow metal tube is filled with aluminum foam, the automobile bumper made of aluminum foam sandwich structure can be obtained, which can not only meet the rigidity and strength requirements, but also improve the energy absorption of the bumper; It is not high, and some current preparation processes are difficult to control, and the problem of uneven pore structure restricts its wide application; the study of low-cost preparation technology of foamed aluminum is of great significance
