Problems solved by technology

However, since the protein in the blood is a large molecule with a large volume, it is difficult to enter the pores of the superabsorbent resin like small molecules such as water and electrolytes, and its blood-absorbing performance cannot be substantially improved.

Abstract

The invention relates to the technical field of high-absorbent resin, in particular to a sodium polyacrylate high-absorbent resin with a high blood-sucking property and a preparation method thereof. The sodium polyacrylate high-absorbent resin with the high blood-sucking property comprises a sodium polyacrylate high-absorbent resin body and a functional monomer N-amino acid-based acrylamide. The functional monomer introduced by the sodium polyacrylate high-absorbent resin with the high blood-sucking property has a natural amino acid structure and has excellent compatibility with proteins, so that the problem of protein adsorption can be effectively solved; the functional monomer also has a carboxyl group, so that on one hand, the structure is similar to the structure of acrylic acid, the compatibility is good, and a neutral reaction can be generated like the acrylic acid; on the other hand, the water solubility is also excellent, and the water absorption and saline absorption of the final resin are basically not affected.

Description

technical field [0001] The invention relates to the technical field of superabsorbent resins, in particular to a sodium polyacrylate superabsorbent resin with high blood-absorbing performance and a preparation method. Background technique [0002] With the improvement of people's living standards, the performance requirements of blood-absorbing materials used in fields such as women's sanitary napkins, pet pads, and blood-absorbing operations are getting higher and higher. Reverse osmosis and other performance requirements, using traditional wood pulp as blood-absorbing materials can no longer meet the requirements. As a superabsorbent material, polymer superabsorbent resin has become the main material, but since the structural design of this type of material focuses on its water absorption performance, and the composition of human blood and animal blood is very complicated, except for most of the water. , and various organic components such as protein, the traditional supe...
