Abstract

The invention discloses a harmful gas absorbable melt-blow filter material and a preparation method thereof. The harmful gas absorbable melt-blow filter material is prepared from the following raw materials in parts by mass: 60-80 parts of polypropylene, 20-40 parts of high-adsorption master batch, 0.5-2 parts of a coupling agent, 0.5-1 part of a dispersing agent and 0.05-0.2 part of an oxidant. The preparation method comprises the following steps: feeding the raw materials into a high-speed mixing machine, uniformly mixing and stirring, feeding into melt-blow non-woven equipment, and performing melt-blow extrusion, hot air traction, cooling and net agglomeration, thereby obtaining the harmful gas absorbable melt-blow filter material. Since the high-adsorption master batch containing synthetic porous calcium metasilicate is added into the polypropylene melt-blow filter material, the filter material which has a certain adsorption property on harmful gases such as formaldehyde, benzene and xylene, and has a high-efficiency filtering property on dust and micro particles in the air can be prepared.

Description

technical field [0001] The invention relates to the technical field of nonwoven materials, in particular to a meltblown filter material capable of absorbing harmful gases and a preparation method thereof. Background technique [0002] The melt-blown method is one of the direct web forming methods of non-woven fabric polymers. High-speed hot air is used to draw the melt, and the polymer is made into non-woven fabrics in one step. Polypropylene meltblown nonwoven fabric has fine fibers, large specific surface area, small pores and high porosity, and is suitable for air filter materials. However, pure polypropylene melt-blown nonwovens rely on pore interception and fiber adsorption of harmful substances, the filtration performance is not enough, and the adsorption capacity of harmful gases needs to be improved. [0003] The molecular formula of the synthesized porous calcium silicate powder is CaSiO 3 ·nH 2 O, the interior and surface are developed with voids, and the appear...
