Technical Field

The invention relates to the technical field of heat insulation structures, in particular to a basalt fiber heat insulation cushion and a manufacturing method thereof.

background

The automobile engine is a device for providing power for an automobile, is the heart of the automobile and determines the dynamic property, the economical efficiency, the stability and the environmental protection property of the automobile; however, in the production and manufacturing process of the automobile, in order to ensure the compactness of the whole structure of the automobile, a part of automobile parts are arranged near the engine, which is called as an engine covering part; in the prior art, the gasket is generally a metal gasket, and the gasket has poor heat insulation performance due to high heat conduction performance of the metal gasket, so that the temperature of the engine covering part is reduced along with the reduction of the temperature of the engine covering part in the working process of the engine, but is still maintained at about 70-80 ℃, and the problem of rusting of the engine covering part is not effectively improved.

Disclosure of Invention

The invention provides a basalt fiber heat-insulating soft cushion and a manufacturing method thereof, and aims to solve the technical problems that the existing metal cushion is poor in heat-insulating performance, and the problem that an engine covering part rusts is not effectively improved.

The scheme for solving the technical problems is as follows: a basalt fiber heat-insulation cushion comprises a heat-insulation cushion base body and at least one aluminum foil glass fiber gasket, wherein the base body comprises a basalt fiber needled felt and two aluminum foil glass fiber cloths, and the two aluminum foil glass fiber cloths are respectively attached to two outer side surfaces of the basalt fiber needled felt; the glass fiber gasket of aluminium foil pastes and locates arbitrary lateral surface of heat insulating mattress base member, the mounting hole has been seted up to the glass fiber gasket of aluminium foil, be formed with on the heat insulating mattress base member with the mounting hole intercommunication runs through the through-hole of heat insulating mattress base member.

the invention also provides a manufacturing method of the basalt fiber heat-insulating cushion, which comprises the following steps: s1, providing a basalt fiber needled felt, two aluminum foil glass fiber cloths and at least one aluminum foil glass fiber gasket; s2, clamping the basalt fiber needled felt between two pieces of aluminum foil glass fiber cloth, and adhering and fixing the basalt fiber needled felt by glue spraying to obtain a heat insulation pad matrix; and S3, adhering the aluminum foil glass fiber gasket to any outer side of the heat insulation pad base body, and forming a through hole penetrating through the heat insulation pad base body from the position of the aluminum foil glass fiber gasket.

By adopting the basalt fiber heat-insulating soft cushion provided by the invention, the basalt fiber needled felt at the inner side is shaped through the aluminum foil glass fiber cloth at the outer side, wherein the basalt fiber can resist the temperature of more than 600 ℃ and can meet the high-temperature service performance, the basalt fiber needled felt not only has the advantages of high temperature resistance, corrosion resistance, stable size, small elongation and shrinkage rate and high strength of basalt fiber fabrics, but also has high porosity because the felt layer fiber is in a single fiber three-dimensional micropore structure, the basalt fiber needled felt aluminum foil glass fiber cloth for the basalt fiber heat-insulating cushion is used as a heat-sealing veneering layer and a water vapor blocking layer, so that the heat-insulating property of the basalt fiber needled felt is effectively ensured, and the water vapor insulating property of the whole structure is ensured; the arrangement of the through holes and the mounting holes is that the basalt fiber heat insulation cushion can be fixedly mounted through fasteners such as bolts.
