Problems solved by technology

CN103171014B (2015-4-15) discloses a preparation method of scientific and technological wood, but the formaldehyde emission of the technological wood is high, the dyeing agent is difficult to penetrate, easy to lose, not weather-resistant, poor compatibility with water-based adhesives, 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 panel, particularly to functional reconstituted lumber. A manufacturing technology of the functional reconstituted lumber comprises the steps of preparing blank veneers through rotary cutting or slicing, and shearing the blank veneers into a required size, so as to obtain A veneers; soaking the A veneers in a ternary compound solution composed of a biomass nanocellulose solubilizer, a fire retardant and an acid dye for toughening, inflaming retarding and dyeing treatment, so as to obtain B veneers; adding a formaldehyde decomposition powder into a modified MUF adhesive, uniformly stirring, and dispensing on the B veneers, so as to obtain C veneers; assembling the C veneers, and carrying out cold pressing treatment, so as to obtain D square lumber; and carrying out compound hot pressing on the D square lumber with a transparent abrasion-resistant surface film adhesive paper layer, wherein the transparent abrasion-resistant surface film adhesive paper layer is a film adhesive paper layer formed through soaking transparent abrasion-resistant surface paper in an amino-formaldehyde resin adhesive solution containing tourmaline powder and Al2O3; the particle size of tourmaline negative ion powder is 500 meshes or above; and the count capacity of negative ions in the Giger. Miller zone is 3000 ions / cc or above. According to the functional reconstituted lumber, the effect that the lumber has multiple functions in a reconstituted decorative lumber manufacturing technology is achieved.

Description

technical field [0001] The invention relates to a furniture board, in particular to a functional recombined board. 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 wood and prolonging the se...
