Method for preparing inorganic composite material by utilizing crop straws
The invention discloses a method for preparing an inorganic composite material from crop straws. The method comprises the steps of pretreatment, unit processing, sizing, paving, forming, primary curing, rough machining, secondary curing, finish machining and the like. The unit processing is to prepare rice straws or wheat straws into 1t; gt is 1 cm, 2 cm, 2-5 cm, 5-10 cm, 10-20 cm, gt, 2 cm, 2-5 cm, 5-10 cm and 10-20 cm; the length specification is equal to the original length of the straw, so that a series of products with different densities and functions can be produced; in the step of sizing, an inorganic adhesive of magnesium-based daub is adopted for glue spraying or glue mixing; according to the primary curing, the magnesium-based plaster material in the blank is in an incomplete curing state, so that the power consumption of rough machining is reduced. The method gives full play to the characteristics of large void ratio, poor thermal conductivity, good sound insulation performance and the like of the crop straws, can be used for preparing inorganic composite materials with multiple functions, can be used for production of wall bodies, fire prevention, decoration and furniture materials, and has remarkable economic, environmental and social benefits.
本发明公开用农作物秸秆制备无机复合材料的方法，包括前处理、单元加工、施胶、铺装、成型、初次养生、粗加工、二次养生、精加工等步骤。所述单元加工是将稻秸秆或麦秸秆制成<2 cm、2 cm~5 cm、5 cm~10 cm、10 cm~20 cm、>20 cm至秸秆原长度等长度规格，用以生产不同密度和功能的系列产品；所述的施胶是采用镁基胶泥的无机胶黏剂进行喷胶或拌胶；所述的初次养生是使坯料中的镁基胶泥材料处于不完全固化状态，以减少粗加工的动力消耗。本方法充分发挥农作物秸秆孔隙比大、导热性差、隔音性能好等特性，可制备具有多种功能的无机复合材料，用作墙体、防火以及装饰、家具材料的生产，具有显著的经济、环境和社会效益。
