Description

Technical Field

[0001] This invention relates to the field of inorganic substrate technology for imitation art paint coating, specifically a preparation process for digital innovative inorganic substrates with imitation art paint effects. Background Technology

[0002] Artistic paint wall decoration is a relatively new type of interior decoration, primarily achieved through on-site application by professional installers. Specifically, the process begins with applying a sealing primer to the wall, followed by a single-color paint. Then, professional installers apply the designed pattern to the wall using scraping or stenciling techniques. However, existing artistic paint stenciling techniques still have the following drawbacks: on-site application of artistic paint requires a high level of expertise; variations in the methods and skill levels of professional installers can lead to significant differences in the final result even with the same design. Furthermore, the manual application of artistic paint requires substantial time and expense, making it unaffordable for the average consumer.

[0149] Comparative Example

[0150] Comparative Example 1:

[0151] The difference between Comparative Example 1 and Example 1 is that in Comparative Example 1, steps S201, S202, and S203, which originally existed in Example 1, were omitted, thereby eliminating the steps of "roller coating of metallic paint", "roller coating of UV color-correcting primer" and "roller coating of UV color-correcting primer". The remaining steps are exactly the same in Comparative Example 1 and Example 1.

[0152] Comparative Example 2:

[0153] The difference between Comparative Example 2 and Example 1 is that in Comparative Example 2, steps S207 and S211 that originally existed in Example 1 were partially omitted, thereby eliminating the steps of "digital printing" and "molding the required texture details on the UV topcoat using a molding device". The remaining steps are exactly the same in Comparative Example 1 and Example 1.

[0154] Comparative Example 3:

[0155] Comparative Example 3 differs from Comparative Example 1 in the following way: in Comparative Example 3, steps S207 and S211 that originally existed in Comparative Example 1 are partially omitted, thereby eliminating the steps of "digital printing" and "molding the required texture details on the UV topcoat using a molding device". The remaining steps are exactly the same in Comparative Example 3 and Comparative Example 1.

[0156] The adhesion, hardness, and abrasion resistance of the paint film in Examples 1-3 and Comparative Examples 1-3 were tested according to the relevant methods in GB / T 37005-2018 "Painted Finish Wood-based Panels". The stain resistance of the paint film was tested according to LY / T 1658-2015 "Direct Printing Wood-based Panels". The contaminants were distilled water and black coffee with a contact time of 16 hours, and ethanol with a contact time of 1 hour. The physicochemical properties were compared with the requirements of standards GB / T37005-2018 and LY / T 1658-2015. The test results are shown in the table below:

[0157]

[0158] The test results in the table show that the surface properties of the boards in Examples 1-3 and Comparative Examples 1-3, such as paint film adhesion, paint film hardness, paint film abrasion resistance, and surface stain resistance, all meet the corresponding requirements. This proves that the preparation process of the digital innovative inorganic board with an imitation art paint effect provided in this application is reliable. At the same time, there is a significant difference in the technical effect of the desired art paint effect between Examples 1 and Comparative Examples 1-3: Examples 1 is closer to the given template art paint effect and is difficult to distinguish with the naked eye, while Comparative Examples 1-3 are all different from the template art paint effect to varying degrees and can be clearly distinguished with the naked eye. This strongly proves that, based on the combined effect of metal paint roller coating, molding topcoat, and digital printing, this application not only successfully simplifies the cumbersome construction operation of art paint, but also significantly reduces labor costs and saves construction time, so that the effect and feel of the boards prepared can fully achieve the effect of art paint.

[0159] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
