Glass fiber infiltrating agent composition as well as preparation method and application thereof

Abstract

The invention provides a glass fiber infiltrating agent composition. The glass fiber infiltrating agent composition comprises a carbon nano material, a dispersant, a polymer emulsion, a coupling agent and a solvent in a mass ratio of (0.05-3):(0.025-4):(0.15-5):(0.05-1.25):(8-49). The infiltrating agent composition has good stability, the deposition of the carbon nano material on fiber surfaces is realized by coating the infiltrating agent composition on glass fiber surfaces, the performance of the glass fibers and the carbon nano material can not be damaged, and the mechanical property and thermal conductivity of the glass fibers and a composite material thereof can be effectively improved at the same time.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a glass fiber sizing composition, a preparation method and an application thereof. Specifically, coating the sizing composition on the glass fiber can effectively improve the thermal conductivity and mechanical properties of the glass fiber and its composite material. Background technique [0002] Glass fiber has the advantages of high mechanical strength, good insulation, strong heat resistance, and good corrosion resistance, and is widely used in the reinforcement of resin-based composite materials. Due to the low surface activity of glass fiber, when used as a composite material reinforcement, it often has the disadvantages of poor compatibility with the matrix resin and weak interfacial interaction. The interface is an extremely important microstructure of composite materials. It acts as a "bridge" connecting the reinforcement and the matrix, and has a crucial impa...
