Problems solved by technology

At present, the coatings include ceramic coatings, Teflon, etc. The thermos cups currently on the market with a ceramic liner are actually a coating baked at a low temperature of 200°C-400°C. The composition itself is organic or contains organic matter, while Organic matter will volatilize when certain conditions (such as acid-base liquids) are met, and the combination of paint and stainless steel is easy to fall off, which affects the effective use of stainless steel thermos cups, that is, it is not suitable for acid-base liquids such as beverages and milk. not suitable for tea
[0004] The ceramic cup itself is an inorganic substance, without the defects of organic substances, and has functions that stainless steel does not have, such as easy cleaning, acid and alkali resistance, and can hold almost all beverages, but it also has a fatal flaw of being fragile, and due to the material quality Tightness is not as good as steel, not suitable for vacuum

Abstract

The invention discloses an enamel vacuum cup and a manufacturing method thereof. The vacuum cup comprises a shell, an inner container and an enamel inner coating on the inner container, and the enamel inner coating is divided into three layers including a ground glaze layer, an enamel layer and an enamel glaze layer. The enamel inner coating is divided into three layers, the ground glaze layer at the bottom layer can improve the adhesive force between the enamel and the surface of the inner container, the enamel layer mainly achieves the purposes of covering the surface of the inner container and forming a complete enamel layer, and the enamel can also improve the surface smoothness and the surface hardness of the enamel, prevent the cup from being scratched in the using process and protect the enamel layer. The service life is prolonged.

Description

technical field [0001] The invention relates to the field of daily necessities, in particular to an enamel vacuum cup and a manufacturing method thereof. Background technique [0002] The stainless steel thermos cup has the advantages of not being afraid of falling, easy to carry, etc. It is a product that is widely accepted by consumers in the current market. The stainless steel thermos cup can be made into a vacuum. There are several ways to treat the inner surface: one is internal throwing, One is electrolysis and the other is spray coating. [0003] As we all know, the acid treatment process during electrolysis has a considerable impact on the environment. At present, all parts of the country are stepping up the regulation of the electrolytic plating industry, so many manufacturers are looking for alternative electrolytic processes, such as coatings. At present, the coatings include ceramic coatings, Teflon, etc. The thermos cups currently on the market with a ceramic l...
