Abstract

The invention provides a basalt fiber heat insulation cushion, and aims to solve the technical problems that an existing metal cushion has poor heat insulation performance and rusting of an engine cover part is not effectively improved. The basalt fiber heat insulation cushion comprises a heat insulation cushion base body and at least one aluminum foil glass fiber gasket; the base body comprises abasalt fiber needled felt and two aluminum foil glass fiber cloths; the two aluminum foil glass fiber cloths are respectively attached to two outer side surfaces of the basalt fiber needled felt; thealuminum foil glass fiber gasket is attached to any outer side surface of the heat insulation cushion base body; the aluminum foil glass fiber gasket is provided with a mounting hole; and a through hole communicating with the mounting hole and penetrating through the heat insulation cushion base body is formed in the heat insulation cushion base body. The invention also provides a manufacturing method of the basalt fiber thermal insulation cushion.

Description

technical field

[0001] 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 technique

[0002] The car engine is the device that provides power for the car. It is the heart of the car and determines the power, economy, stability and environmental protection of the car; Some auto parts are arranged near the engine, which is called the engine cover; the internal temperature of the engine can reach 400-500 degrees Celsius during operation, so it will release a lot of heat, and the engine cover is generally a metal structure, and its surface temperature is too high. Higher will lead to bad problems such as rust, and then affect the service life of the engine cover, so in the automobile manufacturing process, a gasket will be set between the engine and the engine cover. In the prior art, the gasket is generally a metal gasket , due to the high thermal con...
