Synthetic method and application of modified sodium carboxymethyl cellulose polymer
The invention belongs to the technical field of building materials, and discloses a synthetic method and application of a modified sodium carboxymethyl cellulose polymer, a certain amount of allyl alcohol polyether and a small amount of chloroplatinic acid solution catalyst dissolved in isopropanol are mixed, and the mixed solution is stirred and heated; adding a certain amount of low-hydrogen silicone oil, and continuously reacting for a certain time to obtain allyl alcohol polyether modified silicone oil; the preparation method comprises the following steps: dissolving a certain amount of sodium carboxymethyl cellulose in deionized water, adding allyl alcohol polyether modified silicone oil and methyl methacrylate, stirring, and adding an initiator AM; adding a small amount of monomer after stirring, continuously reacting for a certain time, and ending the reaction; and washing the obtained polymer solution with ethanol, carrying out vacuum filtration, washing with deionized water again, and drying to obtain the modified sodium carboxymethyl cellulose polymer. According to the invention, a natural product carboxymethyl cellulose is selected as a raw material, and the prepared modified sodium carboxymethyl cellulose polymer has excellent properties of strong mechanical properties, no toxicity, no allergy and the like.
本发明属于建筑材料技术领域，公开了一种改性羧甲基纤维素钠聚合物的合成方法及应用，将一定量的烯丙醇聚醚和少量的溶于异丙醇的氯铂酸溶液催化剂混合，对混合溶液进行搅拌加热；加入一定量的低含氢硅油，持续反应一定时间后制得烯丙醇聚醚改性硅油；将一定量羧甲基纤维素钠溶于去离子水中，加入烯丙醇聚醚改性硅油、甲基丙烯酸甲酯，搅拌后加入引发剂AM；搅拌后加入少量单体，持续反应一定时间后结束反应；所得到的聚合物溶液用乙醇洗涤，真空抽滤，去离子水再次冲洗后，烘干得改性羧甲基纤维素钠聚合物。本发明选择以天然产物羧甲基纤维素为原料，制备的改性羧甲基纤维素钠聚合物具有力学性能强、无毒、不会引起过敏等优良性能。
