Abstract
A super absorbent thermochromic resin and a preparation method thereof are disclosed. The resin comprises the following components by weight percent: 30-60% of a monomer, 0.01-0.5% of an initiator, 0.01-4% of a dispersant, 0.01-5% of a cross-linking agent, 0-20% of a diluent, 0.5-2% of an auxiliary, 0.1-10% of a thermochromic pigment, and the balance of water. Compared with the prior art, the super absorbent thermochromic resin prepared by the present invention can effectively indicate the temperature changes of the resin in a drying state and a water absorption state through color changes. The reaction finishes in 6-10 min, with a simple process, smooth polymerization, short reaction time and high productivity. The super absorbent thermochromic resin has a good stability and can be widely applied to the medical industry and daily use articles industry.
