Abstract

The utility model relates to a colorful water absorbing gel and a preparation method thereof, and belongs to the technical field of water absorbing gels. The purpose of the invention is to solve the problems of great irritation to human bodies, poor water absorption and environmental pollution of existing hydrogel materials. The colorful water absorbing gel includes, by mass, 60-3000 parts of vegetable oil, 0.6-150 parts of a dispersant, 10 parts of acryloyloxybutylsulfonic acid, 20-600 parts of water, 1.5-2 parts of sodium hydroxide, 10-60 parts of N-octylacrylamide, 0.002-0.07 part of a crosslinking agent, 0.02-0.7 part of an initiator, 0.05-0.5 part of sorbitol, 1-5 parts of a quaternary ammonium salt, 0.0005-0.007 part of a food coloring and 0.1-1 part of sodium carbonate. The vegetable oil and the coloring adopted in the present invention are in food grade, so the safety and sanitation of the water absorbing gel are ensured, and the colorful water absorbing gel has no irritation.

Description

Technical field [0001] The invention belongs to the technical field of water-absorbing gels, and specifically relates to a colorful water-absorbing gel and a preparation method thereof. Background technique [0002] Hydrogel is a polymer material with hydrophilic groups such as carboxyl group, hydroxyl group, amide group, sulfonic acid group, etc. in its structure. It can usually absorb multiple times its own weight of water. The water absorption capacity depends on the hydrophilic group and water. The strength of the hydrogen bonds formed between molecules. Compared with traditional natural water-absorbing materials, water-absorbing gels are mostly three-dimensional network structures formed by physical cross-linking or chemical cross-linking, showing good water retention properties. The hydrogen bond adsorption between the hydrophilic group on the molecular chain and the water molecule has a force far greater than the van der Waals force between water molecules. Under normal t...
