The invention discloses a passive house biomass wallboard which is prepared from the following raw materials in parts by weight: 80-120 parts of fly ash, 40-60 parts of high-density polyethylene, 50-60 parts of straw, 20-30 parts of bamboo fiber powder, 20-30 parts of wood fiber powder, 10-20 parts of cellulose ether and 40-50 parts of water. The preparation method comprises the following steps: (1) weighing the raw materials; (2) mixing cellulose ether and water, and uniformly stirring; (3) adding fly ash, high-density polyethylene, straw, bamboo fiber powder and wood fiber powder, and uniformly stirring; (4) pre-granulating through a double-screw extruder, and carrying out extrusion molding through a double-screw extruder to obtain a semi-finished product; and (5) shaping, cooling to room temperature, cutting, calendaring and laminating to obtain the product. The product disclosed by the invention has the characteristics of light weight, heat insulation, sound insulation, flame retardance, good water resistance and the like, is relatively long in service life, and particularly meets the application requirements of passive house buildings, indoor sound insulation, heat insulation,heat preservation and the like of civil buildings.
本发明公开了一种被动房生物质墙板，由以下重量份的原料制成：粉煤灰80～120份、高密度聚乙烯40～60份、秸秆50～60份、竹纤维粉20～30份、木纤维粉20～30份、纤维素醚10～20份和水40～50份；制备方法为：(1)称取各原料；(2)将纤维素醚和水混合，并搅拌均匀；(3)加入粉煤灰、高密度聚乙烯、秸秆、竹纤维粉和木纤维粉，并搅拌均匀；(4)通过双螺杆机预造粒，再通过双螺杆挤出机挤压成型，得到半成品；(5)定型并冷却至室温，切割、压光贴膜，即得。本发明产品具有轻质、隔热、隔音、阻燃性能和耐水性良好等特点，且使用寿命较长，特别符合“被动房”建筑使用及民用建筑的室内隔音、绝热、保温等应用。
