Embodiment 1

[0013] A basalt fiber heat-insulating soft pad, including a heat-insulating pad base 1 and at least one aluminum foil glass fiber gasket 2, the base 1 includes a basalt fiber needle felt 11 and two aluminum foil glass fiber cloths 12, 13, the two The aluminum foil fiberglass cloths 12 and 13 are attached to the two outer sides of the basalt fiber needle felt 11 respectively; In this embodiment, the aluminum foil fiberglass gasket 2 is pasted on the outer surface of the aluminum foil fiberglass cloth 12; wherein the aluminum foil fiberglass gasket 2 is provided with an installation hole 2a, and the heat insulation pad base 1 is formed with a The installation hole 2a communicates with and passes through the through hole 1a of the heat insulation pad base 1 .

Embodiment 2

[0015] This embodiment provides a method for manufacturing a basalt fiber heat-insulating cushion; it includes the following steps:

[0016] S1, provide one basalt fiber needle felt, two aluminum foil glass fiber cloths and at least one aluminum foil glass fiber spacer.

[0017] Among them, basalt fiber needle felt and aluminum foil glass fiber cloth can be purchased in the existing market, and special customization is not allowed;

[0018] Specifically, in this implementation, basalt fiber needle felt with a thickness of 2.0 mm and aluminum foil glass fiber cloth with a thickness of 0.2 mm are used; the aluminum foil glass fiber gasket is obtained by punching aluminum foil glass fiber cloth with a thickness of 1.0 mm.

[0019] S2, sandwiching the basalt fiber needle-punched felt between two aluminum foil glass fiber cloths, and fixing it by spraying glue to obtain a heat insulation pad base.

[0020] Specifically, in this embodiment, the spray glue used for bonding and fixin...

Embodiment 3

[0024] This embodiment provides a method for manufacturing a basalt fiber heat-insulating cushion, the manufacturing steps of which are basically the same as those in Embodiment 2, except that:

[0025] Basalt fiber needle felt with a thickness of 4.0 mm and aluminum foil glass fiber cloth with a thickness of 1 mm are used.

[0026] Install the basalt fiber heat-insulating cushion made according to Embodiment 2 and Embodiment 3 between the engine and the engine cover, perform a heat-insulation test, and compare it with the existing metal pad to obtain the following table:

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...
