Abstract

The invention discloses a preparation method of a sericite-containing composite with high water absorption and retention performance. The preparation method comprises steps as follows: S1, grinding of sericite: a sericite ore raw material is collected and is roughly broken, the roughly broken sericite ore raw material is ground through a wheel mill, and particles A are obtained after 2-6 times of repeated grinding; S2, processing of the sericite: the particles A are put in a grinder and sufficiently and finely ground for 1-2 h, and a ground substance B is obtained; S3, mixing: carboxymethyl cellulose, cationic starch and polyoxyethylene are added to the ground substance B and sufficiently mixed and stirred for 2-3 h, a sodium sulfate initiator is added for a reaction for 20-40 min at the temperature of 100-120 DEG C, the reaction continues for 30-50 min after the temperature is increased to 120-140 DEG C, and a mixture C is obtained; S4, ultrasonic treatment: the mixture C is ultrasonically dispersed through ultrasonic waves. The preparation process is simple, and the prepared composite has high water absorption and retention performance, has wide application in the aspect of agriculture and chemical engineering and is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of a preparation method of a super water-absorbing and water-retaining composite material containing sericite, in particular to a preparation method of a super water-absorbing and water-retaining composite material containing sericite. Background technique [0002] Drought is a major concern around the world. Since the 1950s, with the rapid development of industry and the rapid expansion of population, the problem of climate warming and drought has become increasingly prominent. These problems have prompted scientists from various countries to begin to study effective methods to solve the drought problem. Before the 1950s, the water-absorbing materials used by humans were mainly natural substances and inorganic substances. Such as natural fiber, natural protein. In the 1950s, Goodrich Company developed the production technology of cross-linked polyacrylic acid, which made water-absorbing polymers used as ...
