Abstract
The invention relates to a novel antiviral PU protective garment, which is made of modified PU, wherein the surface of the modified PU is provided with a bactericide, and the bactericide comprises nano silver, nano zinc oxide, nano copper sulfate, nano silicon dioxide and an auxiliary agent; the degerming agent is sprayed on the surface of PU protective clothing, so that the clothing has good antibacterial effect; the nano silver is a very common nano bactericide, the fine nano zinc oxide particles also have a good antibacterial effect, and the fine nano zinc oxide particles can be firmly bonded together, so that when the bactericide is sprayed on the surface of a garment, a layer of antibacterial protective film can be formed on the surface of the garment, the performance is stable, and the garment can be washed for a plurality of times in high-temperature water; in addition, copper ions are also a good bactericide, and the nano silicon dioxide can effectively bond other substances together due to the microstructure thereof, can also prolong the service life of the whole body, and has certain ultraviolet resistance and oxidation resistance.
Description
Technical Field
The invention relates to protective clothing, in particular to novel antiviral PU protective clothing.
Background
Since the discovery of new coronaviruses, how to treat and protect the coronaviruses becomes a primary problem, researches show that the main transmission route of the new coronaviruses is respiratory droplet transmission and contact transmission.
Droplet propagation mainly comprises two types, namely direct propagation and aerosol propagation; direct transmission refers to infection caused by sneezing, coughing, speaking droplets and direct inhalation of exhaled air in close proximity; aerosol transmission refers to the mixing of droplets in the air to form an aerosol that causes infection after inhalation.
The contact transmission refers to that the spray is on the surface of an article when contacting with pollution, and then contacts with mucous membranes of oral cavity, nasal cavity, eyes and the like to cause infection.
In the process of protecting and treating the new coronavirus, medical care personnel as a combat fighter in the assault battle are key forces for winning the epidemic prevention battle, and the health protection of the medical care personnel is an important link; in this epidemic prevention war, everyone provides tens of thousands of medical protective clothing and medical mask for medical care personnel.
The melt-blown layer in the medical mask can effectively prevent the dispersion of the droplets, and the protective clothing can prevent the droplets from directly dispersing due to the stay on the surface of an object; for the above reasons, both protective clothing and masks are disposable.
The protection of the new coronavirus needs good protection work for every person in the society besides all medical staff; on the other hand, the mask needs to be worn effectively to prevent the transmission of droplets, and the droplets should be prevented from falling on the surface of an article and being transmitted by contact on the surface of clothes, so that the new corona viruses can be eliminated completely only by effective protection in all directions.
However, how to make effective contact and spread becomes a difficult problem, if we also wear the medical protective clothing all the day like the medical care personnel, although a certain effect can be achieved, the cost is too large, and a great burden is easily caused to the lives of people.
Therefore, the novel antiviral protective clothing has good antiviral effect, can effectively prevent the contact and the transmission of new coronavirus, and can be repeatedly used instead of being used for one time like medical protective clothing.
Disclosure of Invention
The invention aims to provide a novel antiviral PU protective garment which has a good protective effect and can be used repeatedly.
The technical purpose of the invention is realized by the following technical scheme: a novel antiviral PU protective garment is made of modified PU, wherein a bactericide is arranged on the surface of the modified PU, and the bactericide comprises nano silver, nano zinc oxide, nano copper sulfate, nano silicon dioxide and an auxiliary agent.
By adopting the technical scheme, the antibacterial agent is sprayed on the surface of the PU protective clothing, so that the clothing has good antibacterial effect; the nano silver is a common nano bactericide, the fine nano zinc oxide particles also have a good antibacterial effect, and the fine nano zinc oxide particles can be firmly bonded together, so that when the bactericide is sprayed on the surface of a garment, a layer of antibacterial protective film can be formed on the surface of the garment, the performance is stable, and the bactericide can be washed for a plurality of times in high-temperature water at 60-80 ℃ for 90-120 times; in addition, copper ions are also a good bactericide, and the nano silicon dioxide is flocculent because of the microstructure, so that concentrated substances can be effectively bonded together, and meanwhile, the substance can prolong the service life of the whole body because of certain ultraviolet resistance and oxidation resistance.
