Anti-static filtration material used at normal temperature and preparation method of anti-static filtration material

Abstract

The invention provides an anti-static filtration material used at normal temperature and a preparation method of the anti-static filtration material. The filtration material comprises non-woven fabric base cloth and a surface layer, wherein the non-woven fabric base cloth and chemical fiber filaments with surfaces which are coated and plated by metal layers are woven in a mixing manner so as to form an anti-static base cloth layer. The preparation method of the anti-static filtration material comprises the following steps: drying the chemical fiber filaments, carrying out physical oil removal and pretreatment, coating and plating the metal layers; then weaving the processed chemical fiber filaments and raw materials of a non-woven fabric base cloth layer in a mixing manner so as to form the anti-static base cloth layer; subsequently mixing, opening, carding and netting raw materials of a non-woven fabric surface layer, adding the anti-static base cloth in the middle, needling and shaping to form the anti-static filtration material. The anti-static filtration material has the advantages of good antistatic property, high uniformity, excellent adhesion property and the like, and can be applied to normal-temperature bag type dust removal in the fields such as waste incineration, thermal power generation, iron and steel and chemical industry. According to the method, the process is simple, safety, reliability, economy and environmental protection are realized; the large-scale mass production is easy to implement.

Description

technical field [0001] The invention relates to the field of industrial textiles, in particular to an antistatic filter material for normal temperature and its preparation. Background technique [0002] In petrochemical, iron and steel smelting, coal-fired power plants, waste incineration, cement and other industrial fields, the smoke generated by some processes has the characteristics of flammable, explosive, high temperature, etc. During the use process due to dust and dust, dust and filter material The friction between them is likely to generate a large amount of static electricity. If the charge cannot be eliminated in time, a fire or explosion will occur. High-temperature smoke and dust put forward higher requirements for the use of filter materials. With the continuous development of science and technology and modern technology, people pay more and more attention to air quality and personal protection. Therefore, it is necessary to use anti-static filter materials to ...

Problems solved by technology

Among them, method (1) has disadvantages such as long production process, complicated process, and poor uniformity; methods (2) and (3) have disadvantages such as unstable antistatic performance, fast attenuation, and large surface resistance.

[0003] At present, there are few researches on anti-static filter materials at home and abroad. The invention patent (201310119167.5) provides an anti-static polytetrafluoroethylene filter bag and its preparation method. The method base fabric is made of polytetrafluoroethylene filaments and stainless steel fibers. Twisted strands are woven through warp and weft phases, and the upper and lower sides of the base fabric are covered with non-woven layers. The antistatic functional layer is different from that of the present invention.
