Embodiment Construction

[0031] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0032] Embodiments of the invention are:

[0033] refer to figure 1 As shown, an adsorption-enhanced filter material includes a filter material body 1, and the filter material body 1 includes a first fiber filament material and a second fiber filament material divided by high melt index polypropylene resin, which are respectively connected through two melt-blown molds The first fiber filaments 21 and the second fiber filaments 22 with different diameters are formed by spraying, the first fiber filaments 21 and the second fiber filaments 22 are randomly arranged to form a fiber network structure, and then mechanically, thermally bonded or chemically reinforced, preferably The use of chemical methods enables the subsequent formation of a non-woven fabric with a rough surface, the grooves of which can maintain the original structure, and the space form...

Abstract

The invention relates to an adsorption-enhanced filter material, which mainly solves the problem of poor adsorption effect of the filter material in the prior art. The content of the propylene-based polymer in one fiber is 65wt%-73wt%, the content of the propylene-based polymer forming the second fiber is 27wt%-35wt%, and the diameter of the first fiber is 2.3μm-5μm, so The diameter of the second fiber filament is 3 μm to 7 μm, the filter body has voids with a pore size of 0.5 μm to 30 μm, and the surface has a concave-convex rough structure, and its surface roughness Ra is 0.2 μm to 16 μm. The attachment process or the wet attachment process makes the tourmaline material adhere to the surface groove structure or gap of the filter material body, and the content of the tourmaline material on the filter material body is 0.01g / ㎡~3g / ㎡.

Description

technical field [0001] The invention relates to an adsorption enhanced filter material. Background technique [0002] At present, in order to prevent the user from inhaling pollutants in the air, a respirator is usually worn on the user's mouth and nose. The charged filter material is usually used as the filter material of the respirator. When the fluid passes through the filter material, the particles carried in the fluid will be captured by the filter material, and these charges can improve the ability of the filter material to capture particles suspended in the fluid. The filter materials used in most of the respirators on the existing market are non-woven fabrics, which include non-woven fabrics made of insulating polymers and non-conductive polymers. Electrically charged insulating objects are usually called "Electret", with the development of the industry, there are now a variety of technologies to produce this product. [0003] Early references to charged filter med...
