Description

Transfer printing multilayer solid wood composite floor

Technical Field

The utility model belongs to the technical field of building material, a solid wood floor is related to, especially, relate to a rendition multilayer solid wood laminate flooring.

Background

The multilayer solid wood composite floor is prepared by coating special paint for the ultraviolet curing floor, which has high performance, high wear resistance and high environmental protection, on a natural rare tree species veneer (veneer) with different thicknesses as a surface layer and a plywood made of solid wood veneers with criss-cross textures as a base material, and is widely applied to the household building material industry. The multilayer solid wood composite floor is a popular decoration in the furniture building material industry at present, but along with the shortage of forest resources, the surface with beautiful patterns is increasingly reduced. However, the market share of the defects of rough grain, single surface pattern, high surface veneer price and the like of the fast-growing wood and the low-grade wood is lower and lower.

The traditional printed floor is prepared by adopting a water-based color paste two-color printing process on a high-density fiber plate blank or a solid wood veneer, and in recent years, the two-color printing is also carried out by adopting UV ink. Both printing processes suffer from the following problems: firstly, the adhesive force between the printing layer and the substrate layer and between the printing layer and the finish paint layer is poor, and the adhesive force between the layers is poor because the printing layer and the finish paint layer cannot be mutually dissolved by adopting a water-based color paste printing process; the UV printing ink is adopted for printing, and no matter three-color synchronous printing or two-color printing is adopted, because the construction times of the coatings are more, the shrinkage rates among the coatings, particularly among the colored paint layer, the ink layer and the finish paint layer, and between the printing layer and the base material are different, the adhesion force of the product can be reduced to different degrees in the later period of use, and faults such as finish paint cracking can occur in severe cases; secondly, both are not synchronous pattern printing, and the simulation degree is poor. In addition, the aqueous color paste printing process has unstable pattern color and large color difference due to volatilization of water and a solvent in the production process.

The following problems are mostly existed in the relevant printed patents such as chinese patent CN 202493014U (CN201220049951.4 a wood printed floor), CN 104960346A (cn201510356498.x a wood floor printing method), etc.: firstly, the printing process is complex, the priming treatment needs to be continuously repeated, then the patterns are printed on the priming surface, and the priming treatment and the adhesion control between layers are complex; secondly, the bottom layer substance is completely covered, the natural texture of a part of wood is not reserved, and the texture patterns are distorted; thirdly, the traditional ink printing mode has long drying time and large energy consumption, and does not meet the requirement of environmental protection; fourthly, the surface of the wood substrate is coated with primer, and then is coated with UV printing ink printing technology, so that wood patterns are lost, the special texture of the wood is lost, and the UV printing ink is added, thereby wasting the cost. The method is characterized in that patterns are printed on the surface of the wood floor and are gradually applied, but the current printed wood floor finished product has poor pattern simulation degree, cannot well retain wood grains, and has relatively complex process, relatively high cost and relatively poor effect.
