Construction solid waste regenerated green cement blanket and preparation method thereof
The invention discloses a construction solid waste regenerated green cement blanket and a preparation method thereof. The preparation method comprises the following steps: crushing waste PP plastic; adding an antioxidant and an ultraviolet light absorber into the crushed waste PP plastic, and extruding to obtain regenerated fibers; chopping the regenerated fibers, and mixing the chopped regenerated fibers with polyester fibers to prepare a fiber web; mixing steel slag, mineral slag and desulfurized gypsum to obtain a base material; calcining the base material, grinding the base material until the specific surface area is 500m < 2 >/kg-800m < 2 >/kg, and adding an activating agent into a grinding train; uniformly mixing the ground base material with the fine aggregate to obtain dry mortar powder; paving the mortar dry powder between two layers of fiber nets, and tightly connecting the two layers of fiber nets through needling to form the construction solid waste regenerated green cement blanket. The method solves the problem that the traditional treatment method of the building wastes may cause environmental pollution.
本发明公开了一种建工固废再生绿色水泥毯及其制备方法，包括：将废弃PP塑料破碎；在破碎后的废弃PP塑料中添加抗氧化剂和紫外线吸收剂挤出获得再生纤维；将所述再生纤维短切与聚酯纤维混合制成纤维网；将钢渣、矿渣和脱硫石膏混合获得基料；将所述基料煅烧后研磨至比表面积为500m2/kg～800m2/kg，在研磨火车中加入激活剂；将研磨后的基料与细集料混合均匀获得砂浆干粉；将所述砂浆干粉摊铺于两层纤维网之间并通过针刺将所述两层纤维网紧密连接形成建工固废再生绿色水泥毯。本发明解决了建筑废弃物的传统处理方法可能会造成环境污染的问题。
