Method for preparing low-density inorganic composite material from straw and wood-bamboo processing residues
The invention discloses a method for preparing a low-density inorganic composite material by utilizing straw and wood-bamboo processing residues, which relates to the technical field of composite material manufacturing and comprises the steps of pretreatment, unit processing, mixing, paving, forming, primary curing, rough machining, secondary curing and finish machining. According to unit processing, rice straw or wheat straw is made into rice straw or wheat straw with the length of 10-20 cm, and wood and bamboo processing residues are made into wood straw or wheat straw with the length of not larger than 5 cm; the density of the composite material ranges from 0.35 g/cm < 3 > to 0.50 g/cm < 3 >; the material mixing comprises the step of uniformly mixing the magnesium-based cement gum, the wood and bamboo processing residues and the straws according to different set mass ratios; and the rough machining is to saw and machine the blank which is not completely cured after the primary maintenance. According to the method, the respective characteristics of the crop straws, the wood and bamboo processing residues and the magnesium-based daub are fully exerted, high-quality utilization of the straws is realized, and the inorganic composite material with multiple functions is prepared and is used for preparing building walls, furniture, decoration and mothproof and anticorrosive materials.
本发明公开一种利用秸秆、木竹加工剩余物制备低密度无机复合材料的方法，涉及复合材料制造技术领域，包括前处理、单元加工、混料、铺装、成型、一次养生、粗加工、二次养生、精加工步骤。所述单元加工是将稻秸秆或麦秸秆制成10 cm~20 cm的长度规格，木竹加工剩余物加工成长度不大于5cm的规格；以制备密度为0.35g/cm3~0.50g/cm3的复合材料；所述混料包括将镁基胶泥、木竹加工剩余物、秸秆按照设定的不同质量比混合均匀；所述粗加工是针对一次养生后不完全固化状态下的坯料进行锯切加工。本方法充分发挥农作物秸秆、木竹加工剩余物和镁基胶泥各自的特点，实现秸秆高质量利用，制备多种功能的无机复合材料，用于制备建筑墙体、家具、装饰和防蛀防腐材料的加工。
