Abstract

The invention discloses a stainless steel vessel with an enamel coating and a preparation method thereof, and belongs to the technical field of stainless steel vessels. The preparation method comprises the following steps: firstly, sandblasting the stainless steel surface of a stainless steel vessel embryo to form a rough surface on the surface of the stainless steel vessel embryo; then, coating the stainless steel surface of the stainless steel vessel embryo with ground coat slurry, specifically, the coating thickness of the ground coat slurry is 60-100 [mu]m; drying and then sintering the stainless steel vessel embryo with the ground coating; coating the surface of the sintered stainless steel vessel embryo with cover coat slurry, specifically, the coating thickness of the cover coat slurry is 170-230 [mu]; and finally, drying and then sintering the stainless steel vessel embryo with the cover coating, and after the sintering is completed, obtaining the target stainless steel vessel.The preparation method is simple, and the enamel coating can adhere more firmly to the surface of the stainless steel alloy.

Description

technical field [0001] The invention relates to a stainless steel vessel and a preparation method thereof, in particular to a stainless steel vessel with an enamel coating and a preparation method thereof, belonging to the technical field of stainless steel vessels. Background technique [0002] Existing stainless steel utensils such as stainless steel heat preservation vessels, stainless steel pots and utensils etc. are all made of stainless steel alloy materials. When stainless steel alloy vessels are used to hold some carbonated soup or alkaline soup, the acid and alkali may corrode the inner cavity of the stainless steel alloy and easily cause it to release metal ions, which is not conducive to human health. [0003] The invention patent with the publication number CN105862039A discloses a production process of heat-resistant glass and enamel coating in the inner cavity of stainless steel vessels. The process includes sanding, spraying, drying and sintering of the embryo...
