Resorcinol-formaldehyde resin와 고무 latex에 의해 표면 개질된 Kevlar 섬유의 고무 접착 특성

Adhesion Properties of Rubber and Kevlar modified with Resorcinol-formaldehyde resin and Rubber Latex

Kevlar was chemically surface modified with resorcinol-formaldehyde(RF) prepolymer and VP rubber latex for application to high strength tirecords. RF prepolymer was easily obtained by polymerization at room temperature in the presence of a base catalyst. The mechanical and thermal properties of Kevlar were not significantly changed during surface treated under various conditions. The change of adhesion with rubber were investigated through H-test method. Maximum increase of adhesion force between rubber and Kevlar was obtained up to 40% than that of untreated one when the fiber was soaked in RFL dipping solution and thermally treated at 170^{circ}C for 3 - 5min.
