Abstract

The invention discloses a modified glass fiber winding wire and a reinforced composite material prepared from the modified glass fiber winding wire, and relates to the technical field of glass fiber reinforced materials. The method is used for solving the technical problems that the heat insulation and compression resistance of the glass fiber winding wires cannot be improved in a continuous treatment mode, and the glass fiber winding wires, thermoplastic resin and auxiliaries are subjected to extrusion injection molding to obtain the composite material with excellent strength, heat insulation and corrosion resistance. According to the modified glass fiber winding wire, the dispersity and interface bonding force of glass fiber yarn are improved through chemical bond grafting; the chemical modifier changes the surface structure of the glass fiber yarn, a rough surface layer structure is formed on the surface of the glass fiber yarn, and hot pressing is performed during heat setting to fully dehumidify and improve the tensile property. According to the reinforced composite material, the moisture-proof heat-preservation middle layer material and the reinforced heat-resisting outer layer material are sequentially coated on the periphery of the reinforced insulation inner layer, and a reinforced composite material finished product with excellent strength, heat insulation and corrosion resistance is obtained through traction and winding.

Description

technical field [0001] The invention relates to the technical field of glass fiber reinforced materials, in particular to a modified glass fiber winding wire and a reinforced composite material prepared therefrom. Background technique [0002] Thermoplastic glass fiber winding wire for extrusion injection molding is an ideal thermoplastic reinforcement material.
