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 boards, in particular to a flame-retardant oriented strand board. The flame-retardant oriented strand board comprises a core layer oriented four-layer laying flame-retardant strand layer and facing layers which are pressed and glued to the upper surface and the lower surface of the core layer oriented four-layer laying flame-retardant strand layer correspondingly. A fire retardant in the flame-retardant strand layer is a magnesium-aluminum nano layered double metal hydroxide fire retardant. The fire retardant comprises, by molar mass, 1-5 parts of magnesium chloride, 0.5-1.2 parts of aluminum chloride, 0.5-1 part of sodium hydroxide and 0.6-1.3 parts of sodium carbonate. The facing layers are made of anyone of decorative paper, veneer or engineered veneer. When the facing layers are made of the decorative paper, balancing layers are further pressed and glued between the core layer oriented four-layer laying flame-retardant strand layer and the facing layers. The engineered veneer with the required thickness is formed by slicing functional engineered wood. The flame-retardant strand layer is vivid in decoration effect, low in cost and good in formaldehyde purifying effect.

Description

technical field [0001] The invention relates to a board, in particular to a flame-retardant oriented strand 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...
