preparation example Construction

[0027] On the one hand, the present invention provides a kind of preparation method of amphiphobic antibacterial easy-to-clean coating, and the method comprises:

[0028] (1) chitosan is placed in glacial acetic acid aqueous solution, carry out ultrasonic stirring, then stir at high speed until chitosan dissolves completely;

[0029] (2) under ultrasonic agitation, in the chitosan solution that step (1) obtains, drip silver nitrate aqueous solution, stir after finishing dropping, then decompression distillation removes glacial acetic acid and water;

[0030] (3) Mix the product obtained in step (2) with silica sol and fluorine-containing polyester polymer, stir evenly at a high speed, and then perform ultrasonic stirring.

[0031] In the present invention, the ultrasonic stirring can be carried out in an ultrasonic stirrer, and the conditions of the ultrasonic stirring preferably include: the frequency is 20-25KHz.

[0032] In the present invention, there is no special requir...

Embodiment 1

[0058] This embodiment is used to illustrate the amphobic antibacterial and easy-to-clean coating of the present invention and its preparation method.

[0059] (1) Preparation of silica sol: at 1000rpm, 18 parts by weight of ethyl orthosilicate are added to 20 parts by weight of ethanol to obtain an ethanol solution of ethyl orthosilicate, and then at 300rpm, add orthosilicate to ethyl orthosilicate 17wt% hydrochloric acid solution was added dropwise to the ethanol solution of the ester until the pH value was 3 to obtain a transparent silica sol.

[0060] (2) Preparation of fluorine-containing polyester polymer: 15 parts by weight of hexafluorobutyl acrylate (purchased from Harbin Xuejia Fluorine Silicon Chemical Co., Ltd.) was placed in a reaction bottle equipped with a condensation and stirring device, and 20 parts by weight were added Parts of 1,4-dioxane and 20 parts by weight of dimethyl sulfoxide, after dissolving hexafluorobutyl acrylate, blowing nitrogen gas to remove ...

Embodiment 2

[0064] This embodiment is used to illustrate the amphobic antibacterial and easy-to-clean coating of the present invention and its preparation method.

[0065] (1) Preparation of silica sol: at 800rpm, 20 parts by weight of ethyl orthosilicate are added to 22 parts by weight of ethanol to obtain an ethanol solution of ethyl orthosilicate, and then at 200rpm, add orthosilicate to ethyl orthosilicate 25wt% nitric acid solution was added dropwise to the ethanol solution of the ester until the pH value was 2 to obtain a transparent silica sol.

Abstract

The invention relates to the field of easy-to-clean coatings, and discloses a preparation method of an amphiphobic, antibacterial and easy-to-clean coating. The method comprises steps as follows: (1) placing chitosan in a glacial acetic acid aqueous solution for ultrasonic stirring, and then stirring the mixture at a high speed until the chitosan is completely dissolved; (2) under the condition of ultrasonic stirring, dropwise adding a silver nitrate aqueous solution to a chitosan solution obtained in Step (1), evenly stirring the mixture after addition, and then performing reduced pressure distillation to remove glacial acetic acid and water; (3) mixing a product obtained in Step (2) with silica sol and fluorinated-polyester-containing polymers, evenly stirring the mixture at a high speed, and then performing ultrasonic stirring. The invention further discloses the amphiphobic, antibacterial and easy-to-clean coating prepared with the method as well as an application of the coating to kitchen appliance products. The coating is easy to clean, acid-and-alkali-resistant, scratch-resistant, antibacterial and widely applicable to the kitchen appliance products.

Description

technical field [0001] The present invention relates to an easy-to-clean coating, in particular to a method for preparing an amphobic, antibacterial, and easy-to-clean coating, the amphobic, antibacterial, and easy-to-clean coating prepared by the method, and the application of the amphiphobic, antibacterial, and easy-to-clean coating in kitchen appliances . Background technique [0002] With the development of the economy and the improvement of living standards, people's requirements for materials are getting higher and higher, and the requirements for the easy-cleaning performance of materials are also getting higher and higher, especially the demand for easy-cleaning materials with antibacterial properties is increasing day by day. [0003] The current kitchen appliance materials can already meet the basic requirements of electrical appliances for materials. However, the current technology is difficult to realize the increasingly strong requirements of users for easy clea...
