Problems solved by technology

However, due to the poor compression and rebound performance of stainless steel materials, the material often needs to be coated with a certain compression and rebound coating on its surface. From these aspects, the product process is very complicated and the cost is very high. Some of them use imported aluminum alloys. The heat insulation is achieved by changing the shape of the metal sheet and adding a single-layer aluminum sheet to a multi-layer structure, but it does not solve the problem from the fundamental material properties.

Abstract

The invention discloses two groups of composite materials respectively having a II-type compound layer and a III-type compound layer, and a preparation process of the two composite materials. The materials are low in manufacture cost, have excellent thermal insulation, temperature resistance, medium resistance and certain compression-resilience property by a simple processing process, can be widely applied to the technical field of sealing and thermal insulation, have a certain effect for making up roughness of the flange surface, and have relatively strong competitiveness and broad market space.

Description

technical field [0001] The invention relates to all the fields that can be applied to heat insulation materials and sealing gaskets in high temperature and high pressure occasions that can be used in automobiles, chemicals, ships, etc., especially a composite material and its preparation process. Background technique [0002] Gasket is an indispensable part of the sealing industry. Its main function is to prevent the medium from leaking from the sealed mechanism. Due to the requirements of its working environment, gaskets are also divided into many types. When sealing between the cylinder block and cylinder head of automobile and motorcycle engines, due to the high temperature of the cylinder block and cylinder head, the medium inside is relatively complicated. At present, stainless steel metal materials are mainly used to process products with certain shapes. However, due to the poor compression and rebound performance of stainless steel materials, the material often needs ...
