Abstract

This invention relates to a super hydrating composite and its preparation. A super hydrating composite, its characteristic is that it mainly consist of fly ash, illite, acrylic acid, acrylamide, hydroxide solution, water-solubility radical polymerization initiator and cross linking agent raw material, the addition quality of fly ash is 20%-60% of acrylic acid, the addition quality of illite is 20%-60% of acrylic acid, the addition quality of water-solubility radical polymerization polymerization initiator is 0.01%-1% of acrylic acid, the addition quality of acrylamide is 5%-60% of acrylic acid, the addition quality of cross linking agent is 0%-0.5% of acrylic acid, the addition quality of hydroxide solution is that neutralization degree is 40-100 mole percentage after neutralizing acrylic acid; The stated fly ash is grinded by vibration milling to make mean diameter be 5.0-15.0 mum,illite is grinded by vibration milling to make mean diameter be 5.0-15.0 mum. The characteristics of invented product are super hydrophilia, high potassium content, low cost, environment compatibility is better than sodium polyacrylate super hydrating resin.

Description

technical field

[0001] The invention relates to a superabsorbent composite material and a preparation method thereof, in particular to a superabsorbent composite material used for drought resistance and water retention in farmland, crop seedling preservation and yield increase, and desert wasteland management. Background technique

[0002] Super Absorbent Polymers (English full name Super Absorbent Polymers, referred to as SAP) is a water-swellable functional polymer material containing strong hydrophilic groups such as hydroxyl and carboxyl groups and having a three-dimensional cross-linked network structure. It absorbs water dozens or even thousands of times its own weight and becomes a gel with good water retention.

[0003] In 1966, Fanta and others of the Northern Research Institute of the United States Department of Agriculture conducted research on starch-grafted acrylonitrile, and since then began the development of superabsorbent resins. Superabsorbent resins have ...
