Abstract

The invention provides an isolation material and a preparation method thereof. The isolation material comprises at least one layer of metal woven mesh and at least one layer of stainless steel fiber mesh; the metal woven mesh and the stainless steel fiber mesh are superposed and fixed layer by layer to form a metal composite mesh, and the metal composite mesh is uniformly coated with an aluminum oxide coating. According to the isolation material and preparation method provided by the invention, the metal woven mesh and the stainless steel fiber mesh are compounded, mesh pores of the metal woven mesh are blocked by the stainless steel fiber mesh, so that the isolation material has good gas permeability and good isolation performance; and the method prevents fibers from drilling out from themetal woven mesh, avoids the situation that the fibers are not easy to separate because the fibers drilled out from the products have solder joints with one another, improves production efficiency ofa stainless steel fiber sintered filter material, and reduces production costs.

Description

technical field [0001] The invention relates to post-processing of filter material production, in particular to an insulating material and a preparation method thereof. Background technique [0002] With the development and popularization of high-tech, various air pollution control filter materials and liquid-solid separation materials for various industries have increased sharply, especially the demand for stainless steel fiber sintered filter materials that can be used in any environment has increased significantly , because the production of stainless steel fiber sintered filter materials requires a high temperature of about 1200 ° C, and the production conditions such as environmental cleanliness are relatively high. The isolation materials that can isolate products from each other and protect products during sintering are currently the bottleneck in the industry. Increased the production cost of its production filter material. [0003] The current isolation materials a...
