Abstract
A preparation method of a carboxymethyl cellulose-phytic acid aerogel material comprises the following steps: step 1) mixing sodium carboxymethyl cellulose with water to obtain a sodium carboxymethyl cellulose solution; (2) mixing the sodium carboxymethyl cellulose solution obtained in the step (1) with the phytic acid solution to obtain carboxymethyl cellulose hydrogel; and (3) drying the carboxymethyl cellulose-phytic acid hydrogel obtained in the step (2) to obtain the polysaccharide aerogel material. The mixing temperature of the sodium carboxymethyl cellulose and the water in the step 1 is 0-40 DEG C, and the dosage ratio of the sodium carboxymethyl cellulose to the water in the step 1 is (200-1000) mg: 20 mL; the volume ratio of the sodium carboxymethyl cellulose solution to the phytic acid solution in the step 2 is (1: 0.1)-(1: 0.2). The carboxymethyl cellulose-phytic acid aerogel material is applied to a flame-retardant material, and the preparation method is simple and reliable.
