preparation example Construction

[0032] A preparation method of a composite anti-fog and haze mask, the specific steps are as follows:

[0033] 1) The inner layer of plant fiber non-woven fabric 25, graphene foam layer 24, nano-silver coated net 23, nano-titanium dioxide coated net 22 and PP non-woven fabric layer 21 are stacked in sequence to form the mask body 2;

[0034] 2) A fixed blind hole is provided on the inner side of the above-mentioned mask body 2, and the fixed blind hole runs through the inner plant fiber non-woven fabric 25, the graphene foam layer 24, the nano-silver coating net 23 and the nano-titanium dioxide coating net 22 in sequence, and the The legs 11 of the support frame 1 are inserted into the fixed blind holes to form a mask assembly;

[0035] 3) Put rubber raw materials into the hot-pressing mold, place the mask assembly in the hot-pressing mold, heat the hot-pressing mold, the heating temperature of the hot-pressing mold is 80-150°C, and the holding time is 15-60 minutes. Make rub...

Embodiment 1

[0038] Embodiment 1: as Figure 1 to Figure 3 Shown, structure of the present invention is included in the inner surface of mouth mask successively from inside to outside and is inner plant fiber non-woven fabric 25, graphene foam layer 24, nano-silver coating net 23, nano-titanium dioxide coating net 22, outer layer The PP non-woven fabric layer 21 and the support frame 1 are composed.

[0039] The support frame 1 is a protruding "convex" type device and is provided with a foot 11 on one side (such as Figure 4 shown), the device passes the inner layer of plant fiber non-woven fabric 25, graphene foam layer 24, nano-silver coated net 23, nano-titanium dioxide coated net 22 and outer PP non-woven fabric layer 21 through the support frame 1 The legs 11 are multi-layer components, the heating temperature of the hot-pressing mold on the hot-press machine is 100° C., the temperature is kept for 40 minutes, and then naturally cooled and hot-pressed to fix the composition. The com...

Embodiment 2

[0045]Embodiment 2: The heating temperature of the hot-press mold on the hot-press machine of the present invention is 110° C., and the temperature is kept for 30 minutes.

[0046] In the production of the graphene foam layer 24, the hot-pressed preform with a thickness of 1.1mm was sintered in a vacuum furnace at 300°C for 50 minutes, and the graphene foam layer prepared by the chemical vapor deposition (CVD) method was controlled to have a thickness of 1.1mm.

[0047] The thickness of the nano-silver coated mesh 23 is 1.0 mm.

[0048] The nano-titanium dioxide coated mesh 22 has a thickness of 0.4mm.

[0049] The thickness of the PP non-woven fabric layer 21 is 0.7 mm.

[0050] Others are the same as in Example 1.

Abstract

The invention relates to a compound anti-haze mask. A mask body of the compound anti-haze mask is sequentially provided with a PP non-woven fabric, a nano titanium dioxide coating net, a nano silver coating net, a graphene foaming layer and an inner-layer plant fiber non-woven fabric module, wherein a supporting frame is installed at the middle position of the mask body, and multiple layers of modules are hot-pressed and fixed through the supporting frame. The compound anti-haze mask can conduct multiple removal on harmful substances such as dust particles, sulfide, nitride, organic hydrocarbon, metal ions and bacteria in hazy weather, is high in space purification rate and good in anti-haze effect and achieves comprehensive filtering and removal of multiple harmful substances in the hazy weather.

Description

technical field [0001] The invention relates to an environmental protection product, which is used for personal protection for removing harmful substances in smog to obtain clean air, and in particular to a graphene composite anti-smog mask. Background technique [0002] Haze weather contains a large number of harmful pollutants, which seriously threaten human health. In autumn, winter and spring, in some areas of my country, especially in the north, smog weather has become the norm, and it is particularly urgent to prevent the damage caused by atmospheric smog pollution to human beings. Wearing a mask is an effective, convenient and economical way to prevent smog pollution. [0003] At present, there are many masks on the market, but the quality of most prepared masks and the ability to eliminate haze pollutants are relatively poor, or only a certain harmful substance in the haze weather can be effectively stopped, and the dust in the haze cannot be effectively removed. M...
