Problems solved by technology

These fibers have their own advantages and disadvantages. Among them, polyester fiber has poor antistatic properties, glass fiber, polyamide fiber and polyphenylene sulfide fiber do not have water repellency, which can easily lead to sticky bags, resulting in failure of filter bags and affecting the effect of flue gas purification. Although polytetrafluoroethylene has water repellency and good corrosion resistance, its price is relatively high, and the requirements for post-processing equipment are also high, which increases the operating costs of enterprises and affects its promotion in enterprises with average profitability. use

Abstract

The invention discloses a finishing method of filter material with functions of water resistance and static resistance. The finishing method comprises the following steps: (10) preparing carbon nanotube finishing liquid; (20) pretreating the surface of the filter material by a cold plasma surface modification method; (30) enabling the filter material pretreated in the step (20) to be coated with the carbon nanotube finishing liquid prepared in the step (10), and baking to obtain the filter material with a coating; and (40) treating the filter material with the coating by a cold plasma polymerization method to obtain the finished filter material. The filter material finished by the finishing method has good functions of water resistance and static resistance.

Description

technical field [0001] The invention belongs to the technical field of textile materials, and in particular relates to a method for finishing filter materials with waterproof and antistatic functions. Background technique [0002] At present, the filter materials used in the flue gas purification systems of coal-fired boilers and waste incinerators are mainly made of polyester fibers, glass fibers, polyphenylene sulfide fibers, polyamide fibers, and polytetrafluoroethylene (PTFE) fibers. These fibers have their own advantages and disadvantages. Among them, polyester fiber has poor antistatic properties, glass fiber, polyamide fiber and polyphenylene sulfide fiber do not have water repellency, which can easily cause bag paste, cause filter bag failure, and affect the effect of flue gas purification. Although polytetrafluoroethylene has water repellency and good corrosion resistance, its price is relatively high, and the requirements for post-processing equipment are also high...
