Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Referring to fig. 1, the inner container structure of the vacuum cup easy to clean of the present invention sequentially comprises a stainless steel substrate layer 1, a sand blasting layer 2 on the surface of the stainless steel substrate layer 1, an organic silicon coating layer 3 on the surface of the sand blasting layer 2, and an inorganic aqueous ceramic coating layer 4 on the surface of the organic silicon coating layer 3, wherein the inorganic aqueous ceramic coating layer is formed by a sol-gel reaction between silica sol and silane, and has a Si-O-Si structure as a film forming substance.
The sand blasting layer 2 is used for improving the adhesive force between the material coating 3 and the stainless steel base material layer 1, and the roughness of the sand blasting layer 2 is controlled to be 0.1-3.5 mu m; the roughness is too large, and after the ceramic coating is sprayed, the surface of the liner of the vacuum cup is uneven and smooth, thus the appearance is influenced. The sand blasting layer 2 is formed by spraying 60-100 meshes of carborundum on the surface of a base material at the pressure of 6-8Kg, and the roughness of the sand blasting layer 2 can be controlled by adjusting the mesh number and the spraying pressure of the carborundum.
The organic silicon coating 3 plays a role of a binder, has good binding force with the stainless steel substrate layer 1 and the inorganic water-based ceramic coating 4, and can prevent the inorganic water-based ceramic coating 4 from falling off due to poor sand blasting treatment of the cup mouth because the inorganic water-based ceramic coating 4 is directly sprayed on the stainless steel substrate layer 1. The thickness of the organic silicon coating 3 is 5-15 mu m, and the organic silicon coating 3 is too thin to cover the stainless steel substrate layer 1, so that the function of bonding between the stainless steel substrate layer 1 and the inorganic water-based ceramic coating 4 is not achieved; too thick a silicone coating 3 is costly.
