A functional heat insulation board for automobiles

Abstract

The invention discloses a functional thermal insulation plate for an automobile. The functional thermal insulation plate comprises a basal body carrier plate, a protective layer, a magnetic layer and a cladding layer, wherein notches are uniformly distributed in one surface of the basal body carrier plate; bulges are uniformly distributed on the other surface of the basal body carrier plate; the protective layer covers the surface in which the notches are distributed of the basal body carrier plate; the surface on which the bulges are distributed of the basal body carrier plate is coated with the magnetic layer; and the cladding layer is compounded on the surface of the magnetic layer. According to the functional thermal insulation plate for the automobile, the structural design of the thermal insulation plate is realized by adopting compounding of multi-layer structures; through the designed pyramid structure or cubic structure, the superficial area of the thermal insulation plate is increased, and sound insulation effects are achieved; the thermal insulation effects of the thermal insulation plate are improved through cooperation between thermal insulation coating and the notches; and the surface adsorption of the thermal insulation plate is realized through the composite magnetic layer.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a functional heat insulation board for automobiles. Background technique [0002] Car body heat shield, also known as heat shield, is a thin metal plate placed between adjacent surfaces in order to reduce the damage of radiation heat transfer surface to other parts in heat transfer engineering. The body heat shield is generally arranged on both sides of the engine and above the exhaust pipe channel at the bottom of the body. It mainly uses the principle of reflection and heat insulation of the heat shield to cut off the transfer of heat, and it also has a certain effect of local noise insulation. [0003] The heat transfer process of car heating parts to the interior of the car body is very unstable, and is greatly affected by factors such as ambient temperature, wind speed, and the motion state of the car itself. It needs to be analyzed from the different motion states of t...

Problems solved by technology

[0012] (6) Double-sided aluminum-coated steel plate: The parts made of double-sided aluminum-coated steel plate have stable structure and size, good heat insulation and sound insulation effects, but the disadvantage is that the anti-corrosion ability is slightly poor, and the specific gravity is large, which is not conducive to reducing the weight of the whole vehicle

But the corrosion resistance of this material is not as good as aluminum plate
