Problems solved by technology

However, alcohol disinfectants have weak bactericidal efficacy and are ineffective against fungi and viruses; peroxide disinfectants are unstable and irritating, and long-term use will endanger human health; polychlorinated disinfectants have little effect on viruses and are Irritating
In addition, these fungicides have a peculiar smell, and the effect is not long-lasting, and microorganisms proliferate immediately within a few hours after sterilization
In addition, these disinfectants that are easy to dissolve have a risk of inhalation for protective products such as masks and gloves
[0004] In recent years, Chinese patent 201811117200.X discloses a clothing disinfectant, which uses alcohol, sodium hypochlorite and natural extracts to disinfect clothes. The disinfectant has the characteristics of good effect and small side effects on the human body, but its bactericidal effect is not strong Defects that are ineffective against fungal viruses, making it difficult to adapt to long-term needs
Chinese patent 201811421664.X discloses an alcohol disinfectant that can be foamed. This patent uses alcohol and PEG-10 polydimethylsiloxane to solve the problems of alcohol not being able to foam and sticking after spraying the surface, but it has not been solved. Difficult to kill viruses and low sterilization efficiency

Embodiment 1

[0045] Example 1 Protective Products Purification Liquid Fungi Effect

[0046] Follow the following formulations to configure antibacterial killing virus protective supplies purification solution: polyethylene glycide hydrochloride: 0.5%; nano-silver gel: 0.05% in the silver concentration, quality concentration; 1% oligonthium chloride 1% quaternary ammonium epitaxyl bromide; mutual leaf white oil: 0.0005%; 4% dimethyl dichlorosilane, 4% phenylchlorosilane, 2% of trimethyl chloride; propylene glycol: 6% ; Water: margin.

[0047] The bacteriostatic performance test for protective supplies was carried out with reference to GB15979-2002, and the purification liquid of protective article was used to purify the liquid, 5 min, 10 min, 20min, and the test was repeated 3 times. The strains used are E. coli (ATCC 8099), Golden Staphylococcus aureus (ATCC 6538), and the antibacterial properties of the protective supplies purified solutions are characterized by its aprotic ratio (ATCC 6538)....

Embodiment 2

[0058] Example 2 Protective Products Purification Liquid to kill viral effects

[0059]Follow the following formulations to configure antibacterial killing virus protective supplies purification solution: polyethylene chloride hydrochloride: 0.02%; nano-silver gel: 0.002% by silver concentration, mass concentration; 0.5% quaternary ammonium chloride , Ethodoalkyl bromide 0.5%; mutual leaf white layer oil: 0.0005%; dimethyl dichlorosilane 2%, phenylchlorosilane 2%, trimethyl chloride 1%; propylene glycol: 3% ; Water: margin.

[0060] According to the identification test of the physical removal method of the "Disinfection Technical Specification" 2002 Edition residual disinfectant, the chemical infectivirus inactivation test was performed on the control of the protective supplies and three consecutive tests. The virus used is an antiviral properties of the anti-viral properties of the protective article purifying liquid (ie, the disinfectant in Table 2), and the viral titer is chara...

Embodiment 3

[0070] With the formulation of Example 1, the protective article purification liquid was configured, and the outer surface of the used KN90 mask was uniformly sprayed. The amount of use of each mask was 2 to 4 ml, and after the surface of the mask was wet, it was dried at 90 ° C for 30 minutes. I.e.

[0071] The PaLAS MFP3000 modular filtration performance tester is used to analyze the interception characteristics and resistance of masks (85 l / min, sodium chloride less than 0.3 um, temperature 25 ° C, relative humidity 75%), using YG461E non-woven gas permeability Test for mask thief (20cm 2 , Pressure 200Pa). The test results are shown in Table 4.

[0072] Table 4 Revoupling and resistance test of postmography after purification liquid for protective supplies

[0073]

[0074] After the treatment of protective supplies, the protective properties of the mask are not substantially affected, and the intervalness of its interval declines, but in line with national standards; its ...

Abstract

The invention belongs to the technical field of antibacterial disinfection of sanitary protective articles, and specifically discloses a long-acting antibacterial and virus-killing sanitary protective article spray and its application. The formula of the spray is: polyhexamethylene biguanide hydrochloride: 0.01 ~1.0%, nano silver gel: based on silver concentration, 0.001~0.1%, quaternary ammonium salt: 0.5~5%, Melaleuca alternifolia oil: 0.0001~0.001%, silicone: 2~15%, propylene glycol: 1-10%, water: balance. The protective product spray of the present invention has a long-lasting antibacterial effect, and the spray is evenly sprayed on the surface of the used sanitary protective product until it becomes wet, and can be used again after being dried. After being washed with water for 3 times, the antibacterial rate remains above 95% under the condition of maintaining good air permeability through the mask treated with the spray of the protective equipment of the present invention.

Description

Technical field [0001] The present invention belongs to the field of antibacterial disinfection techniques of sanitary protective articles, which relates to a protective supplies spray for long-acting antibacterial and killing viral and its applications in the protective mask. Background technique [0002] At present, new coronary virus prevention and control, in order to avoid the use of bacterial virus spread, medical and home fields to increase the use of sanitary protective supplies spraying and propose higher disinfection standards. These sanitary protective supplies often need to experience for a while from the factory to use, during which health protection is easily contaminated by bacterial viruses. In addition, sanitary protective supplies such as protective masks, the experimental gloves are mostly disposable consumables, and there is no energy to effectively kill the virus, causing great resource waste. Therefore, it is necessary to re-antibacterial disinfection treatm...
