Problems solved by technology

[0003] Although many research experiments have been done on the protective effect of masks, there is no effective improvement method for the adverse effects of increased breathing volume during exercise, humid environment and long-term use on the protective performance of masks.
During sports, the comfort performance of masks significantly affects people's choices, and the existing masks not only have poor comfort performance but also reduce the protective effect during sports use.
The effect is not good

Embodiment 1

[0013] A sports protective mask for daily use, comprising the following steps:

[0014] Add the prepared penetrating agent to the spinning precursor, the added mass ratio accounts for 0.4%; heat and stir in a constant temperature heating magnetic stirrer for 2 hours, the stirring temperature is 66 ° C, after natural cooling, shake evenly and use the syringe It was sucked and placed on an electrospinning device, and spun to obtain a fiber membrane with a grammage of 11 g / m2. The prepared fiber membrane is used as the sandwich filter layer of the mask, the surface layer and the back layer are made of non-woven materials, and it can be processed into a folded flat mask with a thickness of 0.6 mm.

[0015] The spinning precursor is made of the following components in parts by weight: 1.4 parts of polyvinylidene fluoride, 5.0 parts of dimethylformamide, and 1.5 parts of dimethyl sulfoxide.

Abstract

The invention relates to a sports daily protective mask, which is prepared by the following steps: adding 0.4-0.5 wt% of a prepared permeable agent into a spinning precursor; putting the mixture intoa constant-temperature heating magnetic stirrer, performing heating and stirring for 2-3 hours at the stirring temperature of 66-70 DEG C, naturally performing cooling, uniformly performing oscillating, performing sucking by using an injector, putting the product on an electrostatic spinning device, and spinning to obtain a fibrous membrane with the gram weight of 11-14g/m<2>. The air permeabilityof the fibrous membrane reaches 890-910mm/s. The prepared fibrous membrane is used as a sandwich filter layer of the mask, a surface layer and a back layer are made of non-woven fabric materials, andthe mask is processed into a folding flat mask. Compared with an existing mask product, the prepared protective mask has the advantages that the comprehensive performance is optimal, the requirementsof the human body for breathing comfort and clean air can be met at the same time, and the application applicability to sports occasions is high.

Description

technical field [0001] The invention relates to the technical field of processing and preparation of a daily-use mask, in particular to a sporty daily-use protective mask. Background technique [0002] At present, indoor and outdoor air pollution in our country is relatively serious, which constitutes a threat to people's physical and mental health to a certain extent. There have also been many persistent air pollution incidents at home and abroad, which have aroused widespread concern from the entire society. Masks can block pollutants such as dust, flying catkins, and droplets, and protect human health. They are important protective items in daily life. Of course, after experiencing the epidemic, people's awareness of protection has been greatly enhanced, and they have also realized the importance of masks. Naturally, masks have entered the daily life of the public as an important item for daily protection, and the protection of masks is naturally the focus of people's att...
