Study on the Hydrophilicity of Collagen Peptide/MVQ Composites
Collagen peptide/Methyl vinyl silicone rubber(MVQ)composites were prepared by adding biomaterial collagen peptide to MVQ using double-roller mill.The results showed that collagen peptide had the effects of structure control agent and delayed vulcanization.With the increasing of the amount of collagen peptide,the composite's hardness increased,and the 100%tensile stress was improved from 1.92 MPa to 2.66 MPa,but its tensile strength and tear strength decreased.When the collagen peptide content was 4 per hundred of rubber,the maximum thermal weight loss rate temperature of the composite was 1.6%lower than that of MVQ.The characteristic peaks of MVQ and collagen peptide appeared in the infrared spectrum of the composites,and the hydrophilicity had been improved to a certain extent.The contact angle decreased by 4.5%at 4 per hundred of rubber.
