Problems solved by technology

However, the kitchen is used as a place for eating and drinking, and the utensils used and stored in it are inevitably in contact with water vapor, oil, salt, sauce, vinegar, etc. If they cannot be cleaned in time, not only will oil and grease accumulate, but it will also bring trouble to future cleaning. It is troublesome, and it will cause rust and corrosion damage to the utensils, or mildew on the surface of the utensils, etc., which seriously affects the service life of kitchen utensils and food hygiene, food safety, etc.
At present, there is no product that is really suitable for self-cleaning protection of kitchen utensils, so the existing technology cannot well meet the urgent needs of users to clean and protect kitchen utensils and other household items, and it is difficult to adapt and meet the improvement and requirements of people's living standards

Embodiment 1

[0023] The preparation method of the present embodiment self-cleaning type antifouling liquid, its steps are as follows:

[0024] (1) Add 2L of absolute ethanol to a three-necked flask equipped with a back distillation device, stir and heat to 40°C, add NaOH solution with a concentration of 20%, and adjust the pH value to 10.4-10.6;

[0025] (2) Add 300mL tetraethyl orthosilicate, keep the above temperature and continue stirring for 60min;

[0026] (3) Add 50mL (C 3 f 7 )-CH 2 -Si(OC 2 h 5 ) 3 , keep the above temperature and continue to stir and mix the reaction for 120min;

[0027] (4) Add 15% HCl solution dropwise at a constant speed within 20 minutes, adjust the pH value of the mixed solution system to 6.8-7.0, keep the above temperature and continue stirring for 30 minutes, and then prepare the self-cleaning antifouling solution after cooling.

Embodiment 2

[0029] The preparation method of the present embodiment self-cleaning type antifouling liquid, its steps are as follows:

[0030] (1) Add 2L of absolute ethanol to a three-necked flask equipped with a back distillation device, stir and heat to 45°C, add tetrabutylammonium hydroxide solution with a concentration of 25%, and adjust the pH value to 10.0-10.2;

[0031] (2) Add 500mL tetraethyl orthosilicate, keep the above temperature and continue stirring for 80min;

Abstract

The invention discloses self-cleaning type anti-fouling liquid. The anti-fouling liquid is prepared via reactive integration of siloxane containing a -CF2 group and a silane coupling agent in a solvent, wherein the structural formula of the siloxane containing the -CF2 group is (R2)-(CH2)m-Si(OR1)3. In addition, the invention further discloses the preparation method of the self-cleaning type anti-fouling liquid. By compound design, the method can be used for preparing the self-cleaning type anti-fouling liquid which has good adhesive force with the surface of a base material, the self-cleaningtype anti-fouling liquid has the properties of water dredging, oil dredging, fingerprint resistance and self cleaning, maintains excellent ageing resistance, corrosion resistance, friction resistanceand chemical stability of an organic silicon material simultaneously, and has a remarkable self-cleaning anti-fouling effect. The self-cleaning type anti-fouling liquid is simple in production process, convenient to use, safe and environmentally friendly, makes up the defect of household supplies such as kitchen utensils in the prior art with respect to clearing self-cleaning protection products,and can be used for better adapting to and meeting improvement and requirement on living standard of people.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to a self-cleaning antifouling liquid and a preparation method thereof. Background technique [0002] Along with the raising of people's living standard, various kitchen electric appliance and utensil as, range hood, gas stove, disinfection cabinet, dishwasher etc., have widely entered in common people's family. However, the kitchen is used as a place for eating and drinking, and the utensils used and stored in it are inevitably in contact with water vapor, oil, salt, sauce, vinegar, etc. If they cannot be cleaned in time, not only will oil and grease accumulate, but it will also bring trouble to future cleaning. It is troublesome, and it will cause rust and corrosion damage to the utensils, or mildew on the surface of the utensils, etc., which seriously affects the service life of the kitchen utensils, food hygiene, and food safety. At present, there is no product that is really...
