Embodiment 1

[0036] The configuration method of vinyltriethoxysilane coupling agent hydrolyzate is as follows: according to dehydrated alcohol: the volume ratio of deionized water=9:1 dehydrated alcohol and deionized water are mixed uniformly, then use mass fraction as 1% hydrochloric acid aqueous solution to adjust the pH value to 4, then add vinyltriethoxysilane in an amount of 0.05 g / mL, and stir to obtain a vinyltriethoxysilane coupling agent hydrolyzate.

Embodiment 2

[0038] The configuration method of aminopropyltrimethoxysilane coupling agent hydrolyzate is as follows: according to dehydrated alcohol: the volume ratio of deionized water=9:1 deionized ethanol and deionized water are mixed uniformly, then use mass fraction as 1% hydrochloric acid aqueous solution to adjust the pH value to 3, then add aminopropyltrimethoxysilane in an amount of 0.03 g / mL, and stir to obtain a vinyltriethoxysilane coupling agent hydrolyzate.

Embodiment 3

[0040] The configuration method of epoxytrimethoxysilane coupling agent hydrolyzate is as follows: according to dehydrated alcohol: the volume ratio of deionized water=9:1 dehydrated alcohol and deionized water are mixed uniformly, then use mass fraction as 1% hydrochloric acid aqueous solution to adjust the pH to 5, and then add epoxytrimethoxysilane in an amount of 0.04 g / mL, and stir to obtain an epoxytrimethoxysilane coupling agent hydrolyzate.

Abstract

The invention discloses an efficient antibacterial agent and a preparation method and an application thereof. The preparation method of the efficient antibacterial agent comprises the following steps: dispersing graphene oxide powder in a solvent, adding titanium chloride powder, performing a ultrasonic stirring reaction, and reacting titanium ions with carboxyl on graphene oxide to generate [-COO] 4-Ti bonds; adding silane coupling agent hydrolysate, and carrying out ultrasonic oscillation reaction, so that silanol generated by hydrolysis of the silane coupling agent reacts with hydroxyl on the graphene oxide to generate Si-O-C bonds; and carrying out suction filtration, washing and freeze drying on the reaction product to obtain the efficient antibacterial agent. In the efficient antibacterial agent, titanium ions and a silane coupling agent are combined with graphene oxide in a chemical bond form, so that the antibacterial agent can be applied to various materials through melt blending and the like. The antibacterial agent is high in light energy utilization rate and remarkable in antibacterial effect, an efficient antibacterial material can be prepared by combining the antibacterial agent with components such as matrix resin, the antibacterial agent can be used for preparing masks, the masks are endowed with efficient antibacterial characteristics, and the use safety of the masks is improved.

Description

technical field [0001] The invention belongs to the technical field of respiratory health protection, specifically relates to a high-efficiency antibacterial agent and a preparation method thereof, and also relates to the application of the high-efficiency antibacterial agent in antibacterial materials and masks. Background technique [0002] A mask is a personal respiratory protection product that can cover the wearer's mouth and nose, and prevent such substances from being inhaled into the human body and endangering people's health by blocking particles, droplets, microorganisms, viruses, etc. [0003] In the prior art, the main body of the mask mainly uses ordinary petroleum-based polypropylene non-woven fabrics as the outermost and innermost fabrics, the middle filter layer uses polypropylene melt-blown cloth to provide filtering, and the strap-type ear straps mainly use Ordinary petroleum-based polypropylene non-woven fabric straps, ear straps are mainly made of spandex...
