Problems solved by technology

CN103171014B (2015-4-15) discloses a preparation method of technological wood, however, the formaldehyde emission of this technological wood is relatively high, the dyeing agent is difficult to penetrate, easy to lose, not weather-resistant, poor compatibility with water-based adhesive, and environmental pollution in the bleaching and dyeing process More serious; because the flame retardant seriously interferes with the color development of the dye and the interface gluing of the dyed veneer, this technical wood has not been treated with flame retardant, and its functionality needs to be improved

Abstract

The invention relates to a furniture board, particularly a recombined decorative material technical wood. The recombined decorative material technical wood is prepared by the following steps: carrying out rotary cutting or shaving to prepare a blank veneer, and cutting the blank veneer into the required size to obtain a veneer A; carrying out immersion toughening flame-retardant dyeing treatment on the veneer A in a three-element compound solution composed of a biomass nano cellulose solubilizer, a flame retardant and an acidic dye to obtain a veneer B; adding formaldehyde decomposition powder into a modified MUF adhesive, stirring uniformly, and coating on the veneer B to obtain a veneer C; and carrying out cold pressing treatment on the veneer C assembly to obtain a batten D, and sawing into the required pattern and size to obtain the finished product. The interface regulation design, biomass nano technique and synergetic compound technique are utilized to effectively solve the problem of diversified matching among the flame retardant, staining agent and adhesive, thereby implementing multiple functions of the one material in the recombined decorative material manufacturing technique.

Description

technical field [0001] The invention relates to a furniture board, in particular to a technical wood for recombined decorative materials. Background technique [0002] As the problem of global warming becomes increasingly prominent and extreme weather occurs frequently, the low-carbon economy with the theme of "low emissions, low pollution, and low energy consumption" is increasingly recognized and respected by people. Under such background conditions, the wood industry is playing an increasingly important role in developing a low-carbon economy and coping with climate change by taking advantage of its inherent "green", "environmental protection" and "clean" characteristics. Wood and wood products have a good carbon sequestration effect. As long as it does not rot or burn, the carbon sequestration function of wood and wood products will continue for a long time and stably. Some carbon fixation time can reach decades, hundreds of years. Therefore, increasing the use of woo...
