Layered composite silver liner vacuum cup and preparation method thereof

Abstract

The invention discloses a layered composite silver liner vacuum cup and a preparation method thereof. An enamel vacuum cup is selected, a vacuum cup body comprises a shell and a liner, wherein an enamel layer is arranged on the inner surface of the liner, and a silver layer is arranged on the enamel layer. The preparation method of the layered composite silver liner vacuum cup comprises the following steps: (1) preparing silver paste; (2) taking the liner, and cleaning the enamel layer of the liner; (3) coating the enamel layer of the liner with the silver paste; (4) feeding the liner into a continuous sintering furnace, and performing drying and sintering; (5) taking out the liner from the continuous sintering furnace, and naturally cooling the liner at room temperature; and (6) vacuumizing the liner, and assembling the liner into the shell to obtain the layered composite silver liner vacuum cup. According to the layered composite silver liner vacuum cup manufactured through the technical scheme, the silver layer is firm and not prone to falling off, and combination of the silver layer and the metal vacuum cup is achieved; and the layered composite silver liner vacuum cup is excellent in heat preservation performance, can be used in daily life, and has extremely high collection value and ornamental effects.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a layered composite silver liner thermos cup and a preparation method thereof. Background technique [0002] A thermos cup, simply put, is a cup that can keep warm. Generally, it is a water container made of ceramic or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids contained inside to achieve the purpose of heat preservation. [0003] With the improvement of living standards, people have put forward higher requirements for thermos cups. In addition to meeting the basic functions, the thermos cups are also required to be rich in ornamental value and collection value. Therefore, there have been silver-lined thermos cups. The liner thermos cup is a thermos cup with a silver layer on the inner wall of the liner. [0004] In the prior art, the silver ...

Problems solved by technology

[0004] In the prior art, the silver sheet is bonded or pasted on the inner wall of the liner by using an adhesive to make a layered composite silver liner thermos cup, but the bonded or pasted silver sheet will not be used in use or under temperature and temperature. In an environment with changing humidity, it is easy to fall off from the inner tank. The thermos cup assembled by threading the silver inner tank will obviously reduce the original design capacity of the thermos cup and reduce the actual use value. The silver inner tank made of silver sheet Insulation cups with silver lining generally have the disadvantages of high silver consumption and high cost, which affect the ornamental value and collection value of the layered composite silver liner thermos cups. There are also thermos cups with electroplating products, but electroplating products are only suitable for ornamental products, holding water for drinking Harmful to the human body
