Preparation method of attapulgite compounded conjugated annular high-temperature-resistant copolymer cement admixture
The invention discloses a preparation method of an attapulgite compounded conjugated annular high-temperature-resistant copolymer cement admixture, which specifically comprises the following steps: removing insoluble impurities in attapulgite, activating in acid, and compounding with a conjugated annular high-temperature-resistant copolymer to obtain the attapulgite compounded conjugated annular high-temperature-resistant copolymer cement admixture. Based on the advantages of high temperature resistance of an inorganic material and good water loss reduction performance of an organic polymer material, the composite polymer cement admixture material with excellent thermal performance and water loss reduction performance is prepared through a simple and efficient physical compounding method. According to the invention, the attapulgite with a chain layered structure is compounded with the polymer, the copolymer can be inserted between layers to form a hybrid structure, and the layered structure of the mineral can provide good protection for the polymer, so that the stability under a high-temperature condition is improved. And the physical compounding method is simple to operate, can efficiently solve the problem of poor thermal stability of the fluid loss agent, and can promote the industrial application of the method due to low cost.
本发明公开了一种凹土复配共轭环状耐高温共聚物水泥外加剂的制备方法，具体包括以下步骤：出去凹土中的不溶杂质后，在酸中进行活化处理后，与共轭环状耐高温共聚物进行复配，得到凹土复配共轭环状耐高温共聚物水泥外加剂。本发明基于无机材料耐高温、有机高分子材料良好降失水性能的优势，通过简单高效的物理复配方法，制得一种具有优异热性能和降失水性能的复合高分子水泥外加剂材料。本发明选用具有链层状结构的凹土与聚合物复配，共聚物可插入层间形成杂化结构，矿物的层状结构可为聚合物提供良好的保护，从而提升高温条件下的稳定性。且物理复配方法操作简单、可高效解决降失水剂热稳定性差的难题，同时其低成本可推动该方法的工业化应用。
