Description

Technical Field

[0001] The present invention relates to the technical field of carbon mineralized materials, and in particular to a negative carbon-based inkjet printing coating product. Background Art

[0002] In recent years, carbonized products with carbonized cementitious materials as the main raw materials have become a research hotspot in the field of green materials. With the continuous maturity of technology, carbon mineralized products (carbon mineralized cementitious materials react with gases containing carbon dioxide) have begun to be gradually applied in various scenarios. However, the artificial building materials obtained are generally gray-black or have dark patterns. In the process of scene application, they are often restricted in use due to factors such as difficulty in decoration and poor aesthetics, which is not conducive to large-scale, multi-scene application and promotion. In response to the above problems, the existing technology generally adopts the method of adding pigments to adjust the appearance color of the product or covering it by applying light-colored paint. However, because the base color is too dark, it needs to be repeatedly applied many times, and in order to make the color richer, other color paints should be applied on the basis of the light color. However, due to the repeated application of the coating, delamination and shedding often occur in the later stage, and the product is too thick, and it is also impossible to achieve arbitrary adjustment of the appearance graphics and color diversity. Therefore, there is an urgent need for a carbonized product with a simple and fast process and arbitrarily adjustable color. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a negative carbon-based inkjet printed coating product, the structural design of which can effectively solve the problems of delamination, excessive thickness of the product, and the inability to adjust the appearance graphics and color arbitrarily.

[0004] The utility model solves the above technical problems through the following technical solutions:

[0005] The utility model provides a negative carbon-based inkjet printing coating product, which comprises a negative carbon matrix layer, an intermediate coating layer, an inkjet layer and a protective layer in sequence from bottom to top or from inside to outside.

[0006] The negative carbon matrix layer is a negative carbon product matrix layer obtained by a carbon mineralization reaction between a carbon-mineralizable cementitious material and a gas containing carbon dioxide (the negative carbon products include but are not limited to plates, aggregates, cultural and creative products, etc.).

[0007] The negative carbon-based inkjet printing coating product is further provided with an SDS adhesive layer between the negative carbon matrix layer and the intermediate coating, a first permeation layer between the intermediate coating and the inkjet layer, and a second permeation layer between the inkjet layer and the protective layer.

[0008] The first permeation layer, the second permeation layer, and the SDS bonding layer are merely a physical superposition relationship of the base layer, the intermediate coating, the intermediate coating, and the protective layer, which is equivalent to a corresponding two-layer superposition structure formed by physical bonding based on the principle of mutual penetration.

[0009] Furthermore, the SDS adhesive layer is a synthetic rubber adhesive (SDS adhesive) layer.

[0010] Furthermore, the intermediate coating includes but is not limited to a water-based paint coating or an oil-based paint coating. The water-based paint coating includes but is not limited to acrylic water-based paint, water-based epoxy paint, and polyurethane water-based paint; the oil-based paint coating includes but is not limited to alkyd oil-based paint and amino oil-based paint.

[0011] Furthermore, the inkjet layer is an inorganic pigment ink for inkjet printing.

[0012] Furthermore, the inorganic pigment ink includes but is not limited to iron oxide red, iron oxide black, iron oxide green, iron oxide yellow, iron oxide orange, iron oxide brown, etc.

[0013] Furthermore, the inkjet protective layer includes but is not limited to acrylic emulsion, pure acrylic emulsion, and silicone acrylic emulsion.

[0014] Furthermore, the thickness of the intermediate coating is 0.5 to 5 mm.

[0015] Furthermore, the thickness of the inkjet protection layer is 0.1 to 2.0 mm.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) The intermediate coating and the negative carbon matrix layer are bonded with SDS adhesive, which has high bonding strength and is not easy to fall off.

[0018] (2) The intermediate coating can isolate the color of the substrate, and through inkjet printing, any color can be adjusted to make the board rich in color and diversified in style.

[0019] (3) The use of solid waste and carbon dioxide increases the added value of waste and is green and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS
