The invention relates to the field of layered products, and discloses a fireproof and flame-retardant aramid filter base cloth, a preparation method and a device, including an aramid base cloth, a fireproof layer, a weather-resistant layer and a reinforcement layer, and the fireproof layer is connected to the aramid base cloth , the weather-resistant layer is connected with the fireproof layer, and the reinforced layer is connected with the weather-resistant layer. Aramid fibers can greatly filter the strength of the base fabric in advance, and then the fireproof layer can be asbestos material, which can enhance the fireproof performance of the aramid fiber, and the weather-resistant layer is a curable epoxy resin coating composition, which can enhance the durability of the base fabric. Thermal performance, the reinforcing layer can be fully aromatic polyester, high-strength polyethylene fiber with ultra-high relative molecular weight, which can increase the strength of the base fabric, so that it is not easy to damage, so as to improve the working life.
Description
technical field [0001] The invention relates to the field of layered products, in particular to a fire-resistant and flame-retardant aramid filter base cloth, a preparation method and a device. Background technique [0002] With the enhancement of people's awareness of environmental protection, the concept of environmental governance has shifted from terminal governance to source governance, that is, reducing pollution. For the field of air filtration, more and more coal-fired power plants and waste incineration plants at home and abroad use bag filter. [0003] The existing filter base cloth has poor fire performance and low strength, which reduces the service life. Contents of the invention [0004] The object of the present invention is to provide a fire-resistant and flame-retardant aramid filter base cloth, a preparation method and a device, aiming at the problem that the existing filter base cloth has poor fire resistance and low strength, which reduces the service ...
