preparation example Construction

[0041] The embodiment of the present invention proposes the preparation method of the antibacterial and easy-to-clean tableware coating of the above embodiment, and the method includes the following steps S1-S2.

[0042] S1, a primer coating is sprayed on the surface of the tableware, and a primer coating is obtained after a curing step.

[0043] In a specific implementation, the curing step of the primer coating is to cure at 20° C.˜25° C. and 60%˜80% relative humidity. The curing time of the primer coating is 12 to 24 hours.

[0044] S2, spray the topcoat on the surface of the primer coating, and obtain the topcoat after the curing step.

[0045] In the specific implementation, the curing step of the topcoat layer is to firstly cure at 20°C to 25°C and 60% to 80% relative humidity, and then to perform the first curing at 200°C to 300°C and 60% to 80% relative humidity. post curing. The first curing time of the top coat is 12-24 hours, and the post-curing time is 12-24 hou...

Embodiment 1

[0049] A bacteriostatic and easy-to-clean tableware coating, which consists of a primer coating and a top coating, the thickness of the primer coating is 15 μm, and the thickness of the top coating is 25 μm. The tablets were ultrasonically cleaned with alcohol for 5 minutes, dried and cooled to room temperature.

[0050] The primer coating is obtained by spraying the primer coating and then curing, and the primer coating is prepared by mixing 10 parts by mass of organic polysilazane, 90 parts by mass of inorganic polysilazane, and 1 part by mass of a defoamer. After finishing, spray the coating on the tableware surface and cure at 20°C and 60% relative humidity for 12 hours.

[0051] The top coating is obtained by spraying the top coating and then curing. The top coating is composed of 10 parts by mass of inorganic polysilazane, 90 parts by mass of organic polysilazane, 5 parts by mass of nano-titanium dioxide It is prepared by mixing parts by mass of defoamer, spraying the p...

Abstract

The embodiment of the invention discloses an antibacterial and easy-to-clean tableware coating, a preparation method and application thereof, and relates to the technical field of coating materials. Wherein, the antibacterial and easy-to-clean tableware coating comprises a base coat and a top coat, the base coat is prepared from a base coat, and the top coat is prepared from a top coat; wherein, in parts by mass, the base coat Including: 10-50 parts by mass of organic polysilazane; 50-90 parts by mass of inorganic polysilazane; 0.5-3 parts by mass of defoamer; 90 parts by mass; 10-50 parts by mass of inorganic polysilazane; 1-10 parts by mass of nano titanium dioxide particles; 0.5-3 parts by mass of defoamer. The bacteriostasis and easy-to-clean tableware coating prepared by the invention has the advantages of bacteriostasis, easy cleaning, wear resistance, high temperature resistance, excellent adhesion and non-stick property, and the like.

Description

technical field [0001] The invention relates to the technical field of coating materials, in particular to a bacteriostatic and easy-to-clean tableware coating and a preparation method and application thereof. Background technique [0002] For a long time, people have used traditional utensils to cook food, but during the cooking process, it is often found that the food sticks to the pan, causing scorching, which brings inconvenience to cooking and also increases the difficulty of cleaning the utensils. At present, the main way to solve the problem of non-stick pans is to coat the traditional tableware with PTFE coating, but the strength of PTFE coating is poor, the wear resistance is not good, and it is easy to fall off. Decomposition products may cause cancer. And with the improvement of living standards, people's requirements for hygiene and safety are getting higher and higher, and the demand for tableware with antibacterial properties is also increasing. However, most ...
