SUPERABSORBENT THERMOCHROMIC RESIN AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/186155
Kind Code:
A1
Abstract:
Disclosed are a superabsorbent thermochromic resin and a preparation method therefor. The resin comprises the following components by weight: monomer: 30-60%; initiator: 0.01-0.5%; dispersant: 0.01-4%; cross-linking agent: 0.01-5%; diluent: 0-20%; aid: 0.5-2%; thermochromic pigment: 0.1-10%; and the balance water. Compared with the prior art, the superabsorbent thermochromic resin prepared by the present invention can effectively indicate temperature variations of the water-absorbent resin in the dry state and the water absorbing state according to color variations; the process is simple, the polymerization reaction proceeds smoothly and can be completed within a short reaction time of 6-10 min, and the productivity is high; the superabsorbent thermochromic resin has desired stability and can be widely applied in medical industry and commodity industry.
