Abstract

The invention relates to a super absorbent degradable colorful crystal soil containing nano-clay and a preparation method thereof. The polymerization of acrylamide monomer M1, sodium acrylate M2, N, N'-methylene-bisacrylamide M3, inorganic nano-clay M4, water soluble biomacromolecule M5 and water soluble pigment M6 are dissolved in water and are synthesized to prepare the crystal soil in redox initiator system. The crystal soil not only processes high water absorption and color absorption, but also has certain mechanical property and biodegradability. The preparation method is simple and has controllable condition without polluting the environment. The water-absorbing capacity and the biodegradation time of the prepared crystal soil can be adjusted by parameters of temperature, PH value, degree of cross linking, dosage and type of water soluble biomacromolecule and nano-clay and reactant proportion, and the appearance color can be adjusted by the pigment type. The crystal soil of the invention is used for environment decoration of household, flower market and gardening, etc, and engineering field of nursery stock breeding, garden greening, agricultural producing, environment improving, revegetating, etc.

Description

technical field [0001] The invention belongs to the technical field of superabsorbent resins and preparation methods thereof, in particular to highly water-absorbent degradable colorful crystal slime containing nano-clay and a preparation method thereof. The prepared crystal slime can be used for environmental decoration in homes, flower markets, gardening, etc. and beautification etc. Background technique [0002] Crystal mud is a kind of soil water-retaining agent with crystal-like transparent lumps, which can repeatedly absorb and store water, nutrients and trace elements, and can maintain and slowly release nutrients, making plants vigorous and fruitful. my country is a big flower producing country. As the cultivation substrate of flowers, crystal mud is an ideal material for soilless cultivation, which has changed the traditional soil cultivation and improved the ornamental effect and economic benefits. As a new type of cultivation substrate, crystal mud is mainly deve...
