Study on Structure Design and Properties of Super Absorbent Copolymerized with Milk Protein Grafted Acrylic Acid

Super absorbent resin(SAR) is a kind of contains strong hydrophilic groups such as carboxyl with certain degree of water swelling type crosslinking polymer. Because it can absorb their hundreds and even thousands of times of water, which are widely used in health product 、dewatering of coal seam and many other fields [1].At present ， there is few study on water absorption performance of protein grafted acrylic acid absorbent resin. Therefore, this article selects the pure milk of JiaBao dairy company production , conducted a series of graft reaction, studied the influence factors such as the initiator, cross-linking agent, neutralization degree ,consumption of milk and PH sensitivity.
