Abstract

The invention discloses a stoving varnish coating with a ceramic-imitating effect for a glass wine bottle, and relates to the field of coatings. The stoving varnish coating with the ceramic-imitating effect for the glass wine bottle is a double-component stoving varnish coating and comprises the following raw materials in parts: a component A: 30-40 parts of modified silica sol, 25-35 parts of a water-based acrylic dispersion, 0.2-0.3 part of a defoaming agent, 0.1 part of fumed silica, 0.2 part of an anti-sagging auxiliary agent, 1.2-2 parts of a dispersing agent, 0.3-0.5 part of a neutralizing agent, 7-8 parts of amino resin, 6-8 parts of titanium dioxide, 3-4 parts of ceramic micro powder, 8-12 parts of a cosolvent and 26-32 parts of deionized water. According to the stoving varnish coating with the ceramic-like effect for the glass wine bottle, the appearance and touch feeling of a glass stoving varnish coating film can be consistent with the ceramic effect, so that the acceptance degree of consumers is increased; in addition, a glassware is arranged inside, the sealing degree of the glassware and the safety of wine products can be guaranteed after wine is contained; meanwhile, the prepared coating is good in stability and the alcohol resistance after baking is excellent.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a ceramic-like baking varnish coating for glass wine bottles. Background technique [0002] Now most of the packaging utensils in the wine industry use glass and ceramics. The price of glass is low, the decorative effect is good, and it is safe and hygienic. No matter what the conditions are, it will not affect the wine inside; and the use of ceramic utensils is favored by more and more customers because of its unique antique beauty. Class, the more willing to use ceramic packaging. However, the price of using ceramic utensils as packaging materials is relatively high, so applying a ceramic-like coating on the outside of the glass has a great advantage in terms of price, product safety, and appearance. [0003] In addition, due to the particularity of packaging products, the main component of alcohol is ethanol, which is an organic solvent, which has a corrosion and swelling e...
