Printing floor and production method thereof

Abstract

The invention belongs to the technical field of wood floors, in particular to a printing floor and a production method thereof. The printing floor comprises a floor base material, wherein a first coating layer is arranged on the surface of the floor base material and is covered with a printed pattern layer, an a second coating layer is arranged on the a printed pattern layer and is provided with a finishing coat layer; and the first coating layer and the second coating layer are anti-shrinkage paint layers made of flexible polymer compositions. The production method of the printing floor comprises the following steps: (a) carrying out the surface-brightening treatment of the floor base material; (b) coating the anti-shrinkage paint layer made of flexible polymer compositions; (c) printing patterns; (d) coating the anti-shrinkage paint layer made of flexible polymer compositions; and (e) coating finishing coat. The printing floor has strong adhesive attraction among the layers, no easy crack and long service life.

Description

technical field [0001] The invention belongs to the technical field of wood floors, in particular to printed floors and a production method thereof. Background technique [0002] The traditional printing floor is to use water-based color paste two-color printing process on high-density blank board or solid wood board. In recent years, UV ink has also been used for two-color printing floor. Both printing processes have the following problems: First, the adhesion between the printing layer and the substrate layer and between the printing layer and the topcoat layer is poor. The water-based color paste printing process is used, because the printing layer and the topcoat layer are not the same system, The problem of poor adhesion between layers is difficult to solve. However, when using UV ink printing, whether it is three-color simultaneous printing or two-color printing, due to the many times of coating construction, the gap between each coating, especially the color paint lay...

AI Technical Summary

Problems solved by technology

Both printing processes have the following problems: First, the adhesion between the printing layer and the substrate layer and between the printing layer and the topcoat layer is poor. The water-based color paste printing process is used, because the printing layer and the topcoat layer are not the same system, The problem of poor adhesion between layers is difficult to solve. However, when using UV ink printing, whether it is three-color simultaneous printing or two-color printing, due to the many times of coating construction, the gap between each coating, especially the color paint layer, ink layer and The shrinkage rate between the topcoat layer and between the printing layer and the substrate is different, resulting in different degrees of adhesion decline during the later use of the product by the customer, and in severe cases, failures such as cracking of the topcoat may occur

Second, both are not synchronous pattern printing, and the degree of simulation is poor

In addition, the color of the pattern is unstable and the color difference is large due to the volatilization of water and solvent during the production process of the water-based color paste printing process.
