Copolymer of Styrene Monomer and Silane Coupling Agent and Manufacturing Method Thereof and Method for Enhancing Adhesion of Fiber Reinforced Polystyrene Resin Composite Material Using the Same

摘要

Disclosed are an adhesion promoter between a fiber and a polystyrene resin, a method for producing the same, and a method for promoting adhesion using the same in a fiber-reinforced polystyrene resin.;The adhesion promoter of the present invention is a copolymer of a styrene monomer and a silane coupling agent, and the copolymer is purified by removing the polymerization inhibitor from the styrene monomer and the silane coupling agent as an initiator using azobisisobutyronitrile or the like. Under the atmosphere, polymerized with benzene as a solvent. Such a copolymer is used as a styrene monomer. Methacryloxypropyltrimethoxysilane ( Poly (styrene-co-) prepared by copolymerizing MPS) (Poly (styrene-CO- -MPS) is a typical example.;The method is also employed in the present invention by hydrolyzing such a copolymer in the presence of a solvent and then applying it to the reinforcing fiber surface to modify the fiber surface and to impregnate the modified fiber with the polystyrene resin.;The present invention is particularly effective when employing glass fibers as reinforcing fibers. According to the present invention, in the fiber-reinforced polystyrene resin composite material, the adhesive force between the reinforcing fibers and the resin is remarkably improved to greatly increase the strength and durability of the composite material, thereby solving a difficult problem in the art.
