example 1

[0018] First weigh 800g of green tea leaves and 300mL of deionized water and mix them into a high-shear dispersing emulsifier, shear and disperse them for 15 minutes at a speed of 7000r / min to obtain a green tea dispersion slurry, and then mix the slurry and distilled water in a mass ratio of After mixing 1:8, put it into an ultrasonic oscillator, vibrate and extract at 70°C for 1 hour, then filter, separate and remove the filter residue to obtain the filtrate; put the above filtrate into a rotary evaporator, and concentrate it to 1% of its original volume by rotary evaporation at 50°C. / 5 to obtain the concentrated solution, then add absolute ethanol 3 times its volume to the concentrated solution, stir evenly, transfer to an ice-water bath at 4°C and let it settle overnight, then centrifuge with a horizontal centrifuge at 3000r / min to remove the precipitate , to obtain the supernatant and freeze-dry it under vacuum at -30°C to obtain a self-made antibacterial agent for later ...

Abstract

The invention discloses a method for preparing a sterilizing and self-cleaning dining table and belongs to the technical field of dining tables. According to the method, an antibacterial active ingredient, i.e., tea polyphenols is extracted from green tea leaves and serves as a natural antibacterial agent, nano-titania with photocatalytic degradation action serves as a self-cleaning material, rich amino groups, which are produced by biological nitrogen fixation of soybean rhizobia, are used for carrying out surface modification on the titania so as to increase surface hydrophilic groups of the titania and enable the modified titania to have an oleophobic effect, a coating material is prepared through compounding the antibacterial agent, the self-cleaning filler and a fluorinated pre-emulsion, the surface of a dining table substrate is coated with the coating material, then, natural air-drying is carried out, and thus the sterilizing and self-cleaning dining table can be prepared. A coating of the dining table prepared by the method has an oleophobic property, so that oil stains hardly remain after wiping, an antibacterial and self-cleaning effect can be achieved under the photocatalysis of the titania and the antibacterial performance of the tea polyphenols, the problem that ordinary dining tables are prone to oil stain remaining and bacterium propagating is effectively solved, the safety of eating of eaters is guaranteed, and thus the application prospect is broad.

Description

technical field [0001] The invention discloses a method for preparing a sterilizing self-cleaning dining table, which belongs to the technical field of dining tables. Background technique [0002] When the waiter is cleaning the table, in order to save trouble, he mixes the tableware and table garbage together, which is an unhygienic way of cleaning the table. During the washing process, bacteria, viruses, parasites and shed dirt on the dining table will inevitably contaminate each other. In addition, most dining tables are never cleaned. It is simply a flat plastic film used to block the garbage on the dining table. There are many viruses and bacteria. Healthy eating is a popular trend in the global catering industry. The green and environment-friendly dining tables sold on the market or being developed are roughly divided into two classes: a class is an automatic dining table, and another kind is an artificial dining table. The main auxiliary function of the self-cleani...
