Abstract

A modified activated carbon fiber GACF composite material mask comprises a surface layer made of spunbonded cloth or knitted cloth, a GACF modified activated carbon fiber composite material, melt-blown cloth, an oxygen anion layer and an inner layer made of spunbonded cloth or knitted cloth from outside to inside; after the five layers are sewn or bonded, ear belts are additionally fixed on the side edges. And a silver ion layer is added on the negative oxygen ion layer. The thickness of the GACF activated carbon fiber composite material is 1-2 mm. Adding a filtering adsorption layer. And add the biological disinfection layer of silver ion layer, overcome the not enough of single melt-blown fabric filtration, obviously, this application scheme is the gauze mask that protective capacities is stronger.

Description

Modified activated carbon fiber GACF composite material mask

Technical Field

The utility model relates to a gauze mask for labor protection, in particular to a gauze mask made of composite materials.

Background

The applicant of the present application filed CN110302755A by the applied science and technology limited of the shenjie activated carbon fiber, in the title of this application, relates to a dry-method modified activated carbon fiber GACF composite material and a preparation method thereof, wherein the dry-method modified activated carbon fiber GACF composite material comprises: 50% of 65% by weight of activated carbon fiber, 35% of 25% by weight of a shaping carrier and 15% of 10% by weight of a binder; according to the dry-method modified activated carbon fiber GACF composite material, the long fiber is used as a shaping carrier of the dry-method modified activated carbon fiber GACF composite material, and after the activated carbon fiber and the long fiber are bonded together by the superfine rubber powder, the long fiber can play a role in shaping the activated carbon fiber and also can play a role in enabling the activated carbon fiber to have a good tensile force; the superfine glue powder is used as an adhesive, so that the activated carbon fiber and long fiber can form three-dimensional adhesion, a ventilation cavity in the dry modified activated carbon fiber GACF composite material can be similar to a sponge air cavity, the activated carbon fiber can still keep good comprehensive adsorption performance, and meanwhile, the activated carbon fiber GACF composite material has good antibacterial activity. The negative oxygen ion layer plays a role in regulating air, the special mask can completely solve the problem of single mask material in the market along with the development of epidemic situation, and meanwhile, the mask can be widely applied to labor protection in industries which are easy to generate harmful gas in production processes such as chemical industry, mechanical industry, ship manufacturing industry, plastic processing industry and the like.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a mask which can be applied to civil and medical protection by utilizing a modified activated carbon fiber GACF composite material. In particular to a filtering and adsorbing layer mask prepared by a dry method modified activated carbon fiber GACF composite material. And a weakly alkaline physical antibacterial layer and a negative oxygen ion layer are added to regulate air.

The technical scheme of the utility model is that: a modified activated carbon fiber GACF composite material mask comprises a surface layer made of spunbonded cloth or knitted cloth, a GACF modified activated carbon fiber composite material, melt-blown cloth, an oxygen anion layer and an inner layer made of spunbonded cloth or knitted cloth from outside to inside; after the five layers are sewn or bonded, ear belts are additionally fixed on the side edges.

And a silver ion layer is added on the spray-melting cloth. The silver ion layer is formed by spraying silver ion salt on the surface of the GACF activated carbon fiber composite material.

The thickness of the GACF activated carbon fiber composite material is 1-2 mm.

The negative oxygen ion layer is spun-bonded cloth coated with negative oxygen ion liquid; the negative oxygen ion layer is sprayed by the negative ion liquid SLF-FU01 model. Or a silver ion layer is added on the negative oxygen ion layer, although the cost is slightly higher, the silver ion layer has the sterilization effect. The combination of the activated carbon fiber 3+ the melt-blown cloth 4 and the filtration and the adsorption disinfection are combined.

Has the advantages that: the utility model discloses utilize dry process modified activated carbon fiber combined material's high adsorption performance and the ability of restraineing the bacterium, the ability of release anion in addition even prepares and filters the adsorbed layer. Overcomes the contradiction of single efficacy and low time efficiency caused by using the melt-blown cloth as the filter layer. The utility model has wider application and stronger efficacy. Obviously, the scheme of the application is a mask with stronger protection capability in all aspects. And a silver ion layer biological disinfection layer can be added, so that the defect of filtering by using melt-blown cloth alone is overcome. By the detection report of Zhejiang national inspection technology company, number 2019(0528), 50 batches of the mask meet the standard of TCTCA1-2015(PM2.5 protective mask), and meet the following inspection items: visual inspection, filtration efficiency, respiratory resistance, total leakage rate, frenulum force, formaldehyde content, PH, decomposable aromatic amine dyes.
