Problems solved by technology

However, it is difficult to directly transfer inkjet technology suitable for ceramic tiles due to the large difference between the surface of wooden floors and ceramic tiles
For now, the application of inkjet printing in the field of wood is still in its infancy, and there are mainly problems such as low printing resolution and poor bonding strength between ink and substrate; especially because the wood interface has many pores and high water absorption. It is easy to absorb water and swell, and the surface is rough and uneven, resulting in low printing resolution, which greatly limits the application of inkjet printing technology in the field of formwork wood floor preparation

Abstract

The invention discloses a tile-like wooden floor. The tile-like wooden floor comprises a wooden base material, an ink-jet pattern layer is arranged on the front face of the wooden base material, and a moisture-proof layer is arranged on the back face of the wooden base material; and the moisture-proof layer is prepared from a moisture-proof coating, the moisture-proof coating comprises the following components: a polyurethane dispersion, a paraffin emulsion and a nano titanium dioxide dispersion liquid, the nano titanium dioxide dispersion liquid is obtained by dispersing nano titanium dioxide into a dispersion system, the mass fraction of the nano titanium dioxide is 10-15%, and the dispersion system comprises organosilane, water and a solvent. The moisture-proof layer can play a role in isolating moisture and preventing mildew, so that the wood base material is prevented from being rotted, and the decorative pattern is prevented from being influenced.

Description

technical field [0001] The invention belongs to the technical field of wood floors, in particular to a tile-like wood floor and a preparation method thereof. Background technique [0002] Wood flooring is loved by people because of its unique and beautiful patterns. However, the moisture-proof and anti-corrosion performance of the back of the existing wood boards is relatively poor, which limits its application. In addition, wooden floors are generally decorated with composite templates. However, due to the natural defects of wood such as stuttering, wood chips need to be selected during the production process, which will bring a lot of labor costs and material waste, which is not compatible with resource conservation and sustainable development. The concept of development does not match. [0003] In order to solve the above problems, some researchers and enterprises have proposed a technical route for applying inkjet printing technology in the production process of wooden ...
