Foaming agent, porous light non-sintered ceramsite and preparation method of porous light non-sintered ceramsite
The invention relates to the technical field of preparation of unfired ceramsite, in particular to a foaming agent, porous light unfired ceramsite and a preparation method of the porous light unfired ceramsite. The foaming agent comprises sodium bicarbonate, a thickening agent, oxalic acid and an alkali activator. The preparation method of the foaming agent comprises the following steps: mixing sodium bicarbonate, a thickening agent and an alkali activator, adding water, and stirring to obtain a mixture; adding oxalic acid into the mixture, stirring, and then sealing to form foam. The porous light unfired ceramsite comprises a foaming agent and a ceramsite base material. The preparation method of the porous light non-sintered ceramsite comprises the following steps: mixing sodium bicarbonate, the thickening agent and the alkali activator, adding water, stirring, adding oxalic acid to form foam, mixing the fly ash, the cement, the waterproof agent and the foam, granulating, spraying water, and naturally curing to obtain the porous light non-sintered ceramsite. High-temperature calcination is not needed, the process is simple, and the obtained ceramsite is low in stacking density, high in compressive strength, capable of meeting the compressive strength requirement in a conventional application environment and wide in application range.
本发明涉及免烧陶粒制备技术领域，更具体而言，涉及一种发泡剂、多孔轻质免烧陶粒及其制备方法。该发泡剂，包括碳酸氢钠，增稠剂，草酸，碱激发剂。所述发泡剂的制备方法包括：将碳酸氢钠、增稠剂和碱激发剂混合后加水搅拌得到混合物；向混合物中加入草酸搅拌，之后密闭形成泡沫。该多孔轻质免烧陶粒包括发泡剂和陶粒基材。该多孔轻质免烧陶粒的制备方法包括：将碳酸氢钠、增稠剂和碱激发剂混合后加水搅拌后加入草酸形成泡沫，将除尘灰、水泥、防水剂与泡沫混合后进行造粒，喷水自然养护后得到。本发明无需高温煅烧，工艺简单，所得陶粒堆积密度低、抗压强度高，满足常规应用环境下的抗压强度要求，适用范围广。
