Thermal-insulation environment-friendly wall building material based on loess and preparation method thereof
The invention discloses a thermal-insulation environment-friendly wall building material based on loess and a preparation method thereof. The thermal-insulation environment-friendly wall building material is prepared from the following components in parts by weight: 85-90 parts of loess, 0.5-1 part of crop straw, 2-5 parts of silty-fine sand and 1-3 parts of lime. The particle size of the loess particles is less than 5 mm, the particle size of the lime is less than 0.5 mm, the crop straws are rolled into sheets, the lengths of the sheets are cut into 30-50 mm, and the lime is powdery. The moisture content of the loess is kept at 15-20%, and the materials can be used as a wall building material after being uniformly mixed in proportion. The wall material is warm in winter and cool in summer, the heat preservation performance, humidity, fire prevention and sound insulation of the wall material are superior to those of a brick wall, the thermal resistance of the wall is 2.4, the thermal resistance of a clay brick wall is 0.6, the heat preservation performance is four times that of the clay brick wall, the wall material is non-toxic, sterile, odorless and low in price, 90% or above ofthe building material can be recycled, and the building material is green and environment-friendly.
本发明公开了一种基于黄土土质的保温环保型墙体建筑材料及其制备方法，按照以下配比组成：黄土85～90份、农作物秸秆0.5～1份、粉细砂2～5份、石灰1～3份。黄土颗粒粒径小于5mm，石灰粒径小于0.5mm，农作物秸秆碾压成片状、长度裁剪成30~50mm，石灰呈粉状。黄土含水率保持15～20％，各材料按比例混合均匀后即可作为墙体建筑材料。本发明的墙体材料冬暖夏凉，保温性能、湿度、防火、隔音均优于砖墙，本墙体热阻为2.4，黏土砖墙为热阻为0.6，保温性能为黏土砖墙的四倍，无毒、无菌、无味，价格低廉，建筑材料90%以上可回收利用，绿色环保。
