Embodiment 1

[0049] A composite non-woven fabric, such as figure 1 As shown, it includes a support layer 1, a fixed film layer 2 on the support layer 1, a granular filter material layer 3 on the fixed film layer 2, a functional layer 4 on the granular filter material layer 3 and a functional layer Protective layer 5 on layer 4.

[0050] Among them, the support layer is 70g / m 2 Polyester ultra-short fiber non-woven fabric; the fixed film layer is 20g / m 2 Environmentally friendly mucous membrane; the particles in the granular filter material layer are modified diatomite particles, specifically diatom particles loaded with nano-titanium dioxide chelated platinum catalyst, spherical in shape, with an average diameter of 0.8mm, and a usage amount of 250g / m 2 ;The functional layer is 25g / m 2 Melt-blown non-woven fabric; the protective layer is 30g / m 2 synthetic fiber non-woven fabrics;

[0051] The preparation method comprises the following steps:

[0052]1) Upper film: Fix the film layer ...

Abstract

The invention discloses a composite nonwoven cloth. The composite nonwoven cloth comprises a support layer, a fixed film layer, a particle filtrate layer, a function layer and a protecting layer, wherein the fixed film layer is arranged on the support layer; the particle filtrate layer is arranged on the fixed film layer; the function layer is arranged on the particle filtrate layer; the protecting layer is arranged on the function layer; the particle filtrate layer is made of porous mineral particles. The composite nonwoven cloth has the advantages that the harmful gas pollutants in air, such as particulate pollutants and formaldehyde, are removed; the efficiency is high, and the lasting and durability effects are realized.

Description

technical field [0001] The invention relates to the technical field of air purification. More specifically, it relates to a composite non-woven fabric and its preparation method and application. Background technique [0002] At present, in the field of air purification, composite non-woven fabric materials are mostly products such as activated carbon particle composite non-woven fabrics, which are commonly called carbon-inserted non-woven fabrics. [0003] Activated carbon carbon interleaved non-woven fabric is the filter element material widely used in the air purification device on the market at present, and its advantage is that the price is low and the market is easy to accept. The disadvantage is that due to the characteristics of the product itself, it is difficult to achieve the effect of effectively eliminating air pollution. Not only is the efficiency low, but it is also easy to be saturated and flammable, especially in wet weather, it is easy to be cemented. After...
