Abstract: 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.
