Problems solved by technology

Referring to the hot-dip aluminum process in my country, there are Sendzimir method and flux method. The Sendzimir method is characterized by high degree of automation, high production efficiency, and stable product processing, but the equipment investment is large and the process is complicated; the flux method has less equipment investment. , simple operation and flexible production, but due to the confidentiality of the technology, no detailed reports have been given on key links such as fluxing agents (Guo Xuxia, Zi Wenhua, Chou Jianjian, hot-dip aluminum plating process and coating analysis, Journal of Kunming University of Science and Technology 2004, 29(2):19-22)

Abstract

The invention relates to a preparation method for a copper / zinc coating on the surface of glass fiber. The preparation method comprises the following steps: pretreating the surface of the glass fiber; chemically plating copper on the surface of the glass fiber; and electroplating zinc on the surface of the glass fiber. The glass fiber can conduct electricity by an electroless plating copper process; and the zinc coating is prepared on the surface of the glass fiber by an electroplating zinc process. By the process, the copper coating is successfully deposited on the glass fiber, the copper content reaches 10 to 80 percent, and the glass fiber is changed from insulation into conduction. The zinc is electroplated on the basis and the zinc content of the coating reaches 10 to 60 percent. The process is low in cost and easy to implement. The prepared zinc coating has excellent performance. The zinc coating with excellent performance is easy to prepare by improving the formula of plating solution. The preparation method for the copper / zinc coating on the surface of the glass fiber is suitable for large-scale production and can replace the conventional preparation process of the composite glass fiber material.

Description

technical field [0001] The invention relates to a glass fiber surface metallization process, and relates to electroless plating and electroplating technology; specifically, it refers to a method for preparing a copper / zinc coating on the glass fiber surface. The invention belongs to the technical field of composite glass fiber material preparation. Background technique [0002] There are many types of inorganic non-metallic materials with excellent glass fiber properties. The advantages are good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, drawing, winding, weaving and other processes. The diameter of its single filament is several microns to more than twenty microns, which is equivalent to 1 of a hair. / 20-1 / 5, each bundle of fiber precursors consists of hundreds or even thousands of monof...
