Baking vanish paint coating metal surface

Abstract

The invention relates to a baking vanish paint coating a metal surface. The baking vanish paint comprises, by weight, 40 to 50% of acrylic resin, 18 to 25% of amino resin, 6 to 12% of cellulose resin and 3 to 4% of an auxiliary agent, with the balance being a solvent, wherein the solvent is prepared by mixing xylene and ethyl ester according to a weight ratio of 50-60%: 40-50%, the cellulose resin is a resin solution with a concentration of 60%, and the auxiliary agent is one or more selected from the group consisting of a drier, a flexibilizer, an antifoaming agent, a leveling agent, a light stabilizing agent, etc. According to the invention, cellulose is added in novel process for the baking vanish paint coating the metal surface so as to form a novel accelerated-drying paint, so the problem of difficult construction is overcome; and only 30 min is needed from spraying of the baking vanish paint on a workpiece to drying of the workpiece and taking of the workpiece off from a production line, so production and coating time is shortened by about 20 min, output is greatly increased, and energy consumption is substantially reduced.

Description

technical field [0001] The invention relates to a coating, in particular to an acrylic baking varnish, which is suitable for bicycles, tricycles, metal tubular and plate objects and other products. Background technique [0002] Acrylic baking paint has a wide range of applications, but in terms of the objective conditions of the original product, difficult construction is a common application problem. Although acrylic resin paint has made innovations in molecular structure, its appearance viscosity is relatively low. The most common hanging paint during construction requires a temperature above 150°C for up to 30 minutes when the paint is heated on the hinge, and the workpiece is out of the production line from spraying to baking. The time is as long as about 1 hour, which is far from enough for the requirements of low carbon emissions. The main problem is that if the heating time is too long, it will consume a lot of electric energy, the production cycle is long, and the pr...

Problems solved by technology

Although acrylic resin paint has made innovations in molecular structure, its appearance viscosity is relatively low. The most common hanging paint during construction requires a temperature above 150°C for up to 30 minutes when the paint is heated on the hinge, and the workpiece is out of the production line from spraying to baking. The time is about 1 hour, which is far from enough for the requirements of low carbon emissions. The main problem is that the heating time is too long, which consumes a lot of power, the production cycle is long, and the production cost is too high, which affects the efficiency of the enterprise.
