Environment-friendly high-strength straw cement brick and preparation method thereof
The invention discloses an environment-friendly high-strength straw cement brick and a preparation method thereof. The method comprises the following steps of: burning straws to obtain plant ash, mixing the plant ash with water to form a plant ash solution, soaking corn straws in the plant ash solution, and separating; airing the corn straws, soaking the corn straws in oil, taking out the corn straws, and airing; heating the plant ash solution to evaporate moisture to obtain powder A; cutting the corn straws into sections with two lengths, and placing the sections in a mold of a hot press in acrossed manner; crushing grain crop straws, uniformly mixing and stirring the crushed grain crop straws, the powder A and a flame-retardant adhesive, and conveying the obtained mixture into a mold for compression molding to prepare a straw bricklaying blank; wrapping the corn straw board with linen soaked with raw lacquer, and maintaining to obtain the environment-friendly high-strength straw cement brick. The production raw materials are crop wastes, the production is energy-saving and environment-friendly, the production process is easy to control, the production cost is low, the product has excellent thermal insulation and fireproof properties, straw mildew and worm damage can be prevented, and cracking of the straw cement brick is effectively avoided.
本发明公开了一种环保高强度秸秆水泥砌砖及其制备方法。该方法先秸秆焚烧得到草木灰，再与水混合形成草木灰溶液，将玉米秸秆浸泡于其中，然后分离；再将玉米秸秆晾干后浸泡于油中后取出晾干；将草木灰溶液加热蒸发掉水分，得到粉体A；将玉米秸秆截成两种长度的段交叉放置于热压机的模具中；将谷类作物秸秆粉碎后与粉体A和阻燃胶黏剂混合搅拌均匀后输送至模具中进行模压成型，制得秸秆砌砖坯料；将玉米秸秆板外包裹上浸泡过生漆的麻布后养护，制成环保高强度秸秆水泥砌砖。本发明的生产原料是农作物废弃料，生产节能环保，生产过程易于控制，生产成本低，产品保温、防火性能优良，还能防止秸秆霉变虫蛀，有效避免秸秆水泥砌砖开裂。
