Description
Technical Field
The invention relates to a production method of a metal printing composite household board, and belongs to the technical field of household board production and manufacturing.
Background
The existing household boards on the market are designed only by considering the use performance and neglecting the aesthetic property. Through careful research, the applicant tries to apply the color coating metal plate to the field of household plates, and the original performances such as wear resistance and the like are kept, so that a better visual effect is expected to be obtained.
The color coating metal plate is a composite material with a color coating formed by firstly removing surface grease from a metal substrate by a continuous unit, carrying out surface coating pretreatment such as surface passivation and the like, coating a primer with specific components on the metal substrate, and finally carrying out roller coating, spraying or screen printing on ink. At present, a color coating metal plate is widely applied to the fields of building curtain walls, door plates, heat insulation plates and the like, but no example of applying the color coating metal plate to a household plate exists. The main reasons are that: on occasions with high wear resistance on floors, after the ink forms the color coating on the primer, the adhesive force between the color coating and the primer often fails to meet the requirement, so that the color coating metal plate often falls off in use, namely, the phenomenon of paint falling is caused, the use attractiveness of the color coating metal plate is influenced, and the visual effect of the color coating metal plate is damaged.
In order to overcome the phenomenon of paint falling, people improve the components of the interface ink in a lot and try to realize good bonding force between a color coating and a substrate through the component improvement of the interface ink. Chinese patent document CN200810054117.2 discloses a code-spraying ink and a preparation method thereof, wherein the code-spraying ink is prepared from the following raw materials and solvents in parts by weight: 15-35 parts of rosin modified resin, 3-15 parts of nitrocotton, 2-10 parts of pigment or dye, 20-50 parts of butanone, 5-20 parts of isopropanol and 10-30 parts of toluene. The ink is stable in ink performance and has high adhesion performance on the surface of a polyolefin material, but the adhesion performance on the surfaces of polyethylene and polypropylene materials is low, the adhesion firmness is poor, and in addition, toluene with high content is adopted in the ink formula, so the environmental protection performance is poor.
Chinese patent document CN101698764A discloses a high-adhesion benzene-free environment-friendly universal code-spraying ink and a preparation method thereof, wherein the code-spraying ink is prepared from the following raw materials and solvents in percentage by weight: 5-10 parts of modified chlorinated polypropylene resin, 1-5 parts of compound resin, 70-89 parts of butanone, 2-6 parts of dye and 0.5-1.5 parts of conductive additive; 1-3 parts of plasticizer, 0.5-1.5 parts of liquid paraffin and 1-3 parts of other auxiliary agents. The jet ink disclosed in the document contains no benzene, is environmentally friendly, and has high adhesion to polyethylene, polypropylene and metal substrates. However, the adhesion between the ink and the polyester substrate was poor.
In summary, how to apply the color-coated metal plate to the home furnishing plate and make the color-coated metal plate and the metal substrate coated with the polyester material have a good bonding force to ensure the beauty of the home furnishing plate is a technical problem which has not been solved in the prior art.
