Description
Technical Field
The invention belongs to the technical field of new material processing, and particularly relates to a nanometer intelligent chip for a universal portable mask and a preparation method thereof.
Background
With the gradual enhancement of the environmental protection concept and the self-protection consciousness of people, the consumption of the protective mask is increased. According to related data reports, the actual consumption of the mask in 2011 in China is 10 hundred million, the actual consumption of the mask in 2012 is increased to 12.5 hundred million, and the actual consumption of the mask in 2013 is increased to 15 hundred million. In 2018, the consumption of the mask all over the country reaches 38 hundred million, and the sales volume achieves 53 hundred million yuan. Moreover, the annual export amount is 15 hundred million, and mask production enterprises reach more than one thousand. The mask has good development tendency no matter the consumption and the number of outlets of the mask are increased, or the number of mask manufacturers is increased. In the domestic market, the quality of the protective mask is different, and although the protective mask has a new national standard, the functional protection is far from the national protection mask imported. People prefer to buy imported protective masks at a high price and also prefer to buy low-price domestic protective masks, important reasons are still that the protective function of the domestic protective masks is poor, in order to solve the technical problems of the protective masks, the invention provides the universal portable mask nano intelligent chip, which not only scientifically and reasonably solves the technical problems of the existing protective masks, but also enhances the multifunctionality, so that the original protective masks have one more protective barrier, and the basic guarantee is provided for human health and disease infection prevention. Compared with the existing mask chips in the markets at home and abroad, the existing mask chips generally adopt activated carbon powder, activated carbon felt and electrostatic filter cotton as core layers, and the adsorption function is mainly physical adsorption. Sterilization can only be accomplished by means of an outer coating of spunbond meltblown nonwoven.
Disclosure of Invention
