Problems solved by technology

There is also a common fashion filter mask on the market, which is made of traditional cotton mask and melt-blown cloth brushed with carbon powder as the filter core layer. This product is beautiful and practical, but the air permeability is not good. In addition, because it does not use activated carbon The particles are carbon powder, so the adsorption efficiency and filtering effect will decrease significantly after a period of use
[0004] The activated carbon particles and melt-blown cloth composite filter materials processed in the market now use hot melt adhesive to a certain extent to play a certain role in fixing, but the use of hot melt powder may affect the adsorption function of activated carbon and the service life of the product.
The adhesive fastness of activated carbon particles with improper use of additives is likely to be insufficient and it is easy to age the non-woven fabric, resulting in poor performance

Embodiment Construction

[0021] The composite filter disc comprises an upper layer of non-woven fabric 1, a lower layer of non-woven fabric 2 and a middle layer of activated carbon particles 3; 2 The average fineness of the fiber is 1-5μm, and the weight is 8-25g / m 2 ; The activated carbon particles in the middle layer 3 are irregular particles and the weight accounts for 95%-97% of the total weight of the material.

[0022] See figure 1 and figure 2 To prepare a raw material roll of melt-blown cloth with a gram weight of 10g, first spread the lower layer of non-woven fabric 2 on the raw material feeding plate 4, and evenly spread the middle layer of activated carbon particles 3 with a diameter of 1mm on the raw material feeding plate through the vibrating screen 5. The input plate 4 is covered with the upper layer of non-woven fabric 1, and the preparation is rolled by a pair of heatable rubber rollers 6 at 55 degrees Celsius, and then transported to the material output plate 8 by a pair of rubber...

Abstract

The invention relates to a composite filter sheet, comprising an upper layer of non-woven fabric, a lower layer of non-woven fabric and an intermediate layer of activated carbon particles; The average fineness of the fiber is 1-5μm, and the gram weight is 8-25g / m2; the composite filter has excellent filtration and adsorption performance, the product structure is ingeniously designed, and it is easy to produce. The carbon particle diameter is large and has high adsorption efficiency for toxic gases. The time is long; in addition, the invention also provides a preparation method of the composite filter.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a composite filter and a preparation method thereof. Background technique [0002] As air pollution continues to increase, air filter materials have gradually become a necessity in people's lives. In recent years, masks such as anti-smog and anti-PM2.5 masks have been selling well in the market, and the growth momentum has not diminished in the slightest. However, this year's 315 party revealed that the activated carbon particle masks currently on the market are far less effective in filtration and adsorption than reported by the product due to processing defects. Even more than half of the anti-haze mask products on the market are unqualified after inspection product. [0003] The long carbon masks that are common in the market now are made of SMS non-woven fabric as the covering material, and the middle is made of melt-blown material brushed with carbon powder as the filte...
