Study on Synthesis and Performances of Casein Resin Grafting Modified by Caprolactam/Acrylic Esters/Vinyl Acetate/Organic Silicone
Casein was grafting modified by caprolactam, acrylic esters, vinyl acetate and organic silicon,in order to improve the film-forming defects of casein such as hard, brittle and excessive moisture absorption performance,etc.In this paper, emulsion properties and film-forming performances were taken as the main indexes to inspect the influence of the type and dosage of organic silicon on the final modified casein resin ,results showed that modified casein could be granted more superior water resistance, smoothness and softness with introducing a relative more amount of A-151. Meanwhile, the structure of modified casein were characterized by FT-IR and TEM, results indicated that: grafting copolymerization between casein and grafted monomers did happen actually.
