Straw board for floor and manufacturing method and application of straw board
The invention discloses a straw board for a floor and a manufacturing method and application of the straw board. The manufacturing method comprises the following steps that rice straws are cleaned upwith water, dried and crushed to obtain a straw crushed material; the straw crushed material is taken to be stir and wash in water, extruding, dehydrating and drying are conducted on the washed straws, the straw crushed material is added into sodium hydroxide solution, ultrasonic soaking at room temperature is conducted, the straw crushed material is neutral after water washing, soaking at room temperature with sulfuric acid solution is conducted after drying, and the straw crushed material is neutral after water washing; the straw crushed material is soaked into sodium silicate solution to obtain straw fibers after drying finally, a hydrophobic material and a modifier are added into the straw fibers, the obtained straw fibers are sent into a stirring-type glue sprayer, a spray gun is arranged in the stirring-type glue sprayer for glue spraying, and the straw fibers are uniformly mixed with an adhesive by stirring; and the straw fibers mixed with the adhesive are transferred into a mould press, and pre pressing and hot pressing in the mould press after paving are conducted to obtain the straw board. By means of the method, the mechanical properties of the board are improved while the application amount of the adhesive is reduced, meanwhile, the product has hydrophobicity and fireproof performance, and secondary processing molding is facilitated.
楼板用秸秆板材及其制造方法和应用，将水稻秸秆用水清洗干净，烘干后粉碎得到秸秆粉碎料；取秸秆粉碎料，在水中搅拌洗涤；将洗涤后的秸秆进行挤压脱水，再烘干；将秸秆粉碎料加入氢氧化钠溶液中，超声室温浸泡，水洗呈中性，沥干后用硫酸溶液中室温浸泡，再水至中性，然后浸泡于硅酸钠溶液中，最后烘干后得到秸秆纤维，再向秸秆纤维中添加疏水材料和改性剂；将所得秸秆纤维送入搅拌型喷胶器，搅拌型喷胶器内设置喷枪进行喷胶，搅拌使秸秆纤维与胶粘剂均匀混合；将拌合了胶粘剂的秸秆纤维转移至模压机中，铺装后在模压机中进行预压和热压，得到秸秆板材。本发明在降低胶黏剂施用量的同时，提升板材的力学性能，同时产品具备疏水性和防火性能，便于二次加工成型。
