Problems solved by technology

As reported in patents CN101302080A and CN101311309A, electroless plating pre-treatment processes such as ultrasonic cleaning, dispersion treatment, roughening treatment, coupling treatment, sensitization, activation treatment, degumming treatment and drying are carried out to prepare conductive and magnetic conductive glass by plating. Fiber, the overall performance of the coating is good, but the stannous chloride solution used in the sensitization process and the hydrochloric acid solution used in the degumming treatment in the pretreatment of the electroless plating process are harmful to the environment, and the overall pretreatment steps are relatively redundant , longer preparation time

Abstract

The invention relates to a basalt fiber material surface metallization method, and belongs to the field of non-metallic material surface treatment. The method comprises the following steps: firstly, carrying out hydrophilic treatment on basalt fibers, respectively carrying out coupling modification and activation treatment on the basalt fibers by using a silane coupling agent and noble metal ions, and then carrying out reduction treatment on the fibers by using a reducing agent capable of reducing the noble metal ions in an activation solution, and finally, the fibers are placed in a chemical plating solution, the surfaces of the basalt fibers are metalized through a chemical plating method, and the basalt fiber-metal core-shell structure is achieved. According to the method, sensitization treatment in a traditional chemical plating method is replaced with a coupling modification treatment process, the adsorption capacity of the basalt fiber to precious metal ions in the activation process is enhanced, and a uniform activation layer is formed on the surface of the fiber. The method is simple, feasible, safe, reliable, economical and environment-friendly, and the obtained metal coating is good in comprehensive performance and convenient for industrial application and production.
