Salt spray test communication cable inner-layer coating material and production method thereof

The invention relates to a salt spray test communication cable inner-layer coating material and a production method thereof. The invention aims at providing an improvement method of a coating material and a corresponding production method of the improved coating material. The production method provided by the invention can effectively improve salt spray corrosion resistance of a coaxial cable. A technical scheme of the production method comprises that the salt spray test communication cable inner-layer coating material comprises raw materials of linear low density polyethylene, ethylene-acrylic acid copolymer, a corrosion inhibitor for copper, calcium stearate, and an antioxidant for copper, wherein a weight ratio of the raw materials is (82-86): (11-15): 1: 1: 1; a buffer agent is benzotriazole or sodium mercaptobenzothiazole; the corrosion inhibitor for copper is methylbenzotriazole; and the antioxidant for copper is an antioxidant MD-1024 or an antioxidant 3114. The production method of the salt spray test
