Abstract

The invention discloses a preparation method of a heat-resistant cable surface material. The tetramethylbisphenol F cyanate resin monomer is dissolved in epoxy resin E44, stirred at 150°C for 80 minutes; Stir at ℃ for 10 minutes; then add isomeric tridecanol polyoxyethylene ether, stir; then add organic solution and filler, and stir at 60°C for 1 hour; then add polymethylsilsesquioxane (molecular weight: 1.2 to 16,000) , stirred to obtain a surface layer solution; finally, the surface layer melt was dried at 80°C, cured at 120°C / 1 minute + 150°C / 30 seconds to obtain a heat-resistant cable surface layer material. In the method disclosed by the invention, each raw material is easy to obtain, the utilization rate is high, and the reaction is uniform; the reaction operation is simple, the reaction process is short, the efficiency is high, and it is suitable for industrial production. There are good applications in the field.

Description

Technical field [0001] The invention relates to a cable material, in particular to a heat-resistant cable surface material and a preparation method thereof, and belongs to the technical field of electronic materials. Background technique [0002] The history of the use of composite materials can be traced back to ancient times. The rice straw or wheat straw reinforced clay used from ancient times to the present and the reinforced concrete that has been used for hundreds of years are both composites of two materials. Composite materials can be divided into two categories: structural composite materials and functional composite materials. Functional composite materials are generally composed of functional body components and matrix components. The matrix not only plays the role of forming a whole, but also can produce synergy or strengthen the function. It is a material that provides other physical properties in addition to mechanical properties, such as: conductive, superconducti...
