Method for modifying crushed bamboo-magnesium oxychloride light composite material through combination of sodium silicate and polycarboxylate superplasticizer
The invention discloses a method for modifying a bamboo particle-magnesium oxychloride light composite material through a combination of sodium silicate and a polycarboxylate superplasticizer. The method comprises the following steps: mixing magnesium chloride, magnesium sulfate and water to prepare saline water, and adding crushed bamboo, the polycarboxylate superplasticizer and a sodium silicate solution into the saline water to obtain a mixture A; mixing magnesium oxide, a thickening agent and a foam stabilizer, and adding the mixture into the mixture A to obtain a mixture B; adding a foaming agent into the mixture B to obtain slurry; pouring the slurry into a mold, and carrying out maintenance, standing, curing, and demolding successively to obtain the crushed bamboo-magnesium oxychloride light composite material modified by the combination of the sodium silicate and the polycarboxylate superplasticizer. According to the method, the mechanical property and the water resistance of the modified crushed bamboo-magnesium oxychloride light composite material can be improved at the same time; and the preparation method has the advantages of being low in cost, environmentally friendly, low in energy consumption and the like and is beneficial to industrial application.
本发明公开了一种硅酸钠‑聚羧酸减水剂复合改性竹碎料‑氯氧镁轻质复合材料的方法，包括将氯化镁、硫酸镁与水混合配置成盐水，将竹碎料、聚羧酸减水剂和硅酸钠溶液加入盐水中得到混合物A，将氧化镁、增稠剂和稳泡剂混合加入混合物A中得到混合物B，将发泡剂加入混合物B中，得到浆料，将浆料倒入模具中养护和静置固化，脱模后，得到硅酸钠‑聚羧酸减水剂复合改性竹碎料‑氯氧镁轻质复合材料。本发明的方法可以同时提高改性竹碎料‑氯氧镁轻质复合材料的力学性能和耐水性能，制备方法具有成本低、绿色环保、能耗低等优点，有利于工业化应用。
