Abstract

The invention relates to the technical field of filter materials, in particular to an ultra-low resistance melt-blown filter material and its production process; it includes 85-90% of polypropylene resin and the rest of polypropylene masterbatch by weight percentage; wherein, the The polypropylene masterbatch is composed of the following raw materials in parts by weight: 85-100 parts of polypropylene resin, 6-12 parts of ethylene-methacrylate copolymer, 3.0-3.6 parts of diatomite, 1.8-2.5 parts of nano-silver, 2.0 parts ~2.8 parts of nano-calcium carbonate, 1.2-1.6 parts of nano-titanium dioxide, 2.5-3.2 parts of composite anti-aging agent, 0.8-1.2 parts of antioxidant, 1.5-2.2 parts of nucleating agent, 1.0-1.3 parts of slip agent, 0.6-1.0 parts lubricant and 1.0-1.5 parts of ultraviolet absorber; the melt-blown filter material produced by the present invention not only has certain antistatic performance, antibacterial performance and anti-aging performance; in addition, it also has good air permeability and gram weight index; The mechanical properties are also relatively good; effectively ensuring the quality and quality of the produced melt-blown filter material.

Description

technical field [0001] The invention relates to the technical field of filter materials, in particular to an ultra-low resistance melt-blown filter material and a production process thereof. Background technique [0002] Haze is a combination of fog and haze. Smog is common in cities. In many areas of China, fog is incorporated into haze as a disastrous weather phenomenon for early warning and forecasting, collectively referred to as "smog weather". Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of a high-density population will inevitably emit a large amount of fine particulate matter (PM2.5). Once the emission exceeds the atmospheric circulation capacity and carrying capacity, the concentration of fine particulate matter will continue to accumulate. Widespread smog. [0003] Compared with fog, haze is more harmful to people's health. Since the diameter of the fine powdery floating par...
