High temperature resistance filter cloth

Abstract

The invention discloses a high temperature resistance filter cloth and a preparation method thereof. The high temperature resistance filter cloth comprises a first support layer, a functional layer and a second support layer in turn; bonding layers are arranged between the first support layer and the functional layer and between the functional layer and the second support layer for tightly combination; the first and the second support layers are made of metal meshes. The invention have the advantages that the metal meshes are adopted as the support layers on the surfaces of the filter cloth for the first time, and the metal meshes have the functions of high electric conductivity, high thermal conductivity, high strength, high temperature resistance, corrosion resistance, and the like; thehigh temperature resistance is good, and the filter cloth provided by the invention can resist high temperature of 300 DEG C or higher; the antistatic property of the filter cloth is efficient and durable; the metal meshes as the support layers can provide certain function of a skeleton, thereby enabling the filter cloth to obtain high modulus of elasticity and improving the filter cloth in wrinkle resistance; the metal meshes as the support layers also have the function in surface protection.

Description

Technical field [0001] The invention relates to a filter cloth with high temperature resistance, which is mainly used in the fields of filter element, purifier, air protection and purification. Background technique [0002] At present, the carbon-filled fabrics on the market use non-woven fabrics and other materials as the support layer, which cannot be used in the high temperature field. High temperature is generally defined as the temperature above 200 ℃. Because the non-woven fabric material does not have the temperature resistance above 200 ℃, it is limited In addition, the activated carbon in the carbon cloth has the characteristics of being flammable under open flame or high temperature, so the application of the carbon cloth in the high temperature field is even more limited. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a high temperature resistant f...

Problems solved by technology

[0002] At present, the charcoal cloth on the market uses non-woven fabrics and other materials as the supporting layer, which cannot be used in high-temperature fields. High temperature is generally defined as a temperature above 200°C. Since non-woven fabrics are not resistant to temperatures above 200°C, there are limitations. In addition, the activated carbon in the carbon cloth has the characteristics of being flammable when exposed to an open flame or high temperature, so it limits the application of the carbon cloth in the high temperature field.
