Abstract
The present invention relates to an eco-friendly super-absorbent carboxymethyl cellulose polymer and a preparation method therefor, wherein the eco-friendly super-absorbent carboxymethyl cellulose polymer of the present invention is prepared by crosslinking carboxymethyl cellulose using an electron beam and thus has excellent biodegradability, and the polymer is free of toxic materials or microplastics and exhibits high absorbency and thus is suitable for use in sanitary products such as sanitary pads and diapers.
Claims5
A method for preparing an eco-friendly super absorbent carboxymethyl cellulose (CMC) polymer, the method comprising:
- (a) mixing 5 to 25 wt % of a CMC with a viscosity of 1,000 cps or more and 75 to 95 wt % of water;
- (b) irradiating the mixture with an electron beam;
- (c) drying the irradiated mixture at 10 to 70° C.;
- and
- (d) pulverizing the dried mixture.
