Problems solved by technology

[0008] However, the overall performance has not improved significantly based on the original solvent-based products, and the drying speed of the paint film still drops relatively.
In addition, customers generally put forward relatively high requirements in terms of paint film feel and scratch resistance. The performance of these three types of current coating resins for wine bottles is average in this area, and there is no further improvement in alcohol resistance.

Description

Technical field [0001] With the enrichment of people's material culture, coating on wine bottle glass is becoming more and more common. In the early days, people usually used solvent-based amino baking varnishes; recently, for environmental protection and health and safety considerations, more and more water-based baking varnishes are used. For example, the two-component baking varnish of water-based high acid value resin and water-based amino resin is often used. [0002] Coatings used for wine bottle coating generally require relatively good adhesion; good hardness and scratch resistance; very good alcohol resistance; at the same time, the coating must have good gloss and color retention; as a baking paint Under the premise of ensuring sufficient storage stability and operating time, it is also hoped that its curing temperature is as low as possible and curing time is as short as possible in order to reduce energy consumption and improve efficiency.
