Process for covering water transfer printing on wood plastic, plastic and metallic products

Abstract

The invention discloses a water-coated transfer printing process for wood, plastic, and metal products, which comprises the following steps: according to the necessary background color, spraying oil paint on the surfaces of the wood, the plastic, and the metal products; spreading a water-coated transfer printing film on the water surface by putting the surface with printing ink patterns to face upwards; spraying an activator on the water-coated transfer printing film evenly through a spray gun when the water-coated transfer printing film is softened and spread levelly; and according to the positions of the patterns floating on the water surface, pressing an obtained product downwards into the water for 2 to 10 seconds and taking out the product, and transferring the patterns on the water-coated transfer printing film to the surface of the product under the action of water pressure. The process further comprises the following steps: washing the obtained product clean by water and then putting the product into a drying furnace to be dried at a temperature between 50 and 70 DEG C; or using a blowing gun to blow off the water, drying the product at room temperature, spraying a layer of transparent oil paint on the surface of the product, putting the product in the drying furnace and curing the product at a temperature between 50 and 160 DEG C. The compositions of the activator are as follows according to percentage by weight: 33 percent of xylene, 15 percent of butyl acetate, 15 percent of methyl acetate, 10 percent of methyl isobutyl ketone, 5 percent of isobutanol, 8 percent of isophorone, 5 percent of methyl methacrylate, 7 percent of cyclo ethyl ketone, and 2 percent of nitrocellulose resin.

Description

technical field [0001] The invention generally refers to a coating water transfer printing process, and in particular relates to a water transfer printing coating process for printing patterns on the surface of complex and changeable products. technical background [0002] The existing printing process can usually only print calligraphy and painting patterns on objects with regular shapes, such as planes, spherical surfaces, cylindrical surfaces, etc., but cannot print calligraphy and painting patterns on objects with complex and changeable surface shapes. Industrial products such as mobile phone shells, anti-theft doors, various furniture, home appliances, etc., because the surface shape is relatively complex and changeable, they cannot be decorated with printed calligraphy and painting patterns, or in order to be able to print calligraphy and painting patterns on the surface of the product, they have to be printed The product is designed with a rigid structure, which affec...

[0002] The existing printing process can usually only print calligraphy and painting patterns on objects with regular shapes, such as planes, spherical surfaces, cylindrical surfaces, etc., but cannot print calligraphy and painting patterns on objects with complex and changeable surface shapes. Industrial products such as mobile phone casings, anti-theft doors, various furniture, home appliances, etc., because the surface shape is relatively complex and changeable, they cannot be decorated with printed calligraphy and painting patterns, or in order to be able to print calligraphy and painting patterns on the surface of the product, they have to be printed The product is designed with a rigid structure, which affects the appearance and image of the product and market sales, resulting in a low price
