Abstract

The invention belongs to the technical field of glass surface modification, and relates to a glass surface grafting method, especially to a method for grafting polymer chains on the surface of glass through free radical polymerization initiated by redox. According to the invention, glass flake processed by a silane coupling agent is added into a monomer aqueous solution containing a few CuSO4 to react for 3-4 hours at the temperature of 80 DEG C, so as to obtain a glass flake sample with the polymer chains being fixed on the surface. The operation technology provided by the invention is simple; the grafting effect is obvious; raw materials used are products sold in the market, can be used without complex purification process, and are low in price and easily available; water is used as a reaction medium, thus avoiding complex solvent recovery process in the later period, reducing cost and minimizing the pollution to the environment; and grafted sheet glass or glass fiber products can be applied to reinforce the bond property between resins and glass in composite materials, and has an extensive industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of glass surface modification, and relates to a glass surface grafting method, in particular to a method for initiating free radical polymerization and grafting polymer chains on the glass surface through redox. Background technique [0002] In recent years, thermoplastic resin-based composites based on general-purpose engineering plastics and high-performance engineering plastics have become more and more popular due to their advantages such as high toughness, short molding cycle, reusability, convenient maintenance, and low cost. Concern; my country's research on thermoplastic resin-based composite materials began in the late 1980s, and has achieved rapid development in the past ten years. In 2000, the output reached 120,000 tons, accounting for about 17% of the total output of resin-based composite materials. The matrix used The materials are still mainly PP and PA, and the reinforcement materials are mainl...
