Abstract

The invention relates to a production method of a protective filtering material. The protective filtering material adopts a four-layer structure: a first layer is a protective layer; a second layer is filter cotton; a third layer is a spraying melting filtering material with an antibacterial function and a protective layer structure with the antibacterial function; 1, a first layer material is 35g /m<2> gray antibacterial spunbond, 2, a second layer material is 200g /m<2> activated carbon filter cotton, 3, a third layer material is a 60g /m<2> antibacterial filter cotton, the filtration efficiency of 0.3 mu m NaCl particles under 85LPM conditions is up to 97%; and 4, a fourth layer material is 35g /m<2> white antibacterial spunbond.

Description

A kind of production method of filtering material
Technical field
A kind of invention is related to a kind of production method of protective filtering material.In order to meet wanting for electric welding respiratory protection material Ask, using several functions material adapted, meet dust-proof, anti-harmful gass, antibacterial functions.Traditional some materials are solved in electric welding The single problem of filtering function under work use environment.
Background technology
The protective material requirement of weldering application is dust-proof, also will anti-harmful gass.The protective mask of current many electric welders There are no the two functions.
The content of the invention
The main contents of patent of the present invention have following several respects：
1. the present invention devises a kind of filtering material using four layer material structures, and the material is mainly used in electric welder's respiratory protection mistake Filter is used.
2. the material primary structure is：Ground floor is protective layer, can be spunbond, and spunbond grammes per square metre can be mainly 10- 40g/m2, is mainly characterized by with antibacterial functions.
The second layer is filter cotton, and the material that the filter cotton is made up of electret fiber and activated carbon granule, the material have Very high holds dirt performance and the absorbability to harmful gass；Third layer is the melt-blown filter materials with antibacterial functions, the material The filter efficiency of material is higher, there is provided a gradient filtration performance, and under the air quantity of 85LPM, efficiency is more than this layer of strainability 95%；4th layer is the protective layer structure with antibacterial functions, can be spunbond, woven fabric or looped fabric etc..
Specific embodiment：
The present invention adopts four-layer structure：Ground floor is protective layer；The second layer is filter cotton；Third layer is molten with antibacterial functions Blown filter materials；4th layer is the protective layer structure with antibacterial functions.
Ground floor is：35g/m2 Lycoperdon polymorphum Vitt antibacterials are spunbond；The second layer is 200g/m2 activated carbon filter cottons；Third layer is 60g/ The antimicrobial filtering cotton of m2, filter efficiency reach 97% to 0.3 μm of NaCl particle filtration efficiencys under the conditions of 85LPM；4th layer It is spunbond for 35g/m2 white antibacterials.

Claims (6)
