Abstract

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 communication cable inner-layer coating material comprises the following steps of 1, raw material reparation, 2, master batch preparation, 3, additive preparation and 4, extrusion and cutting.

Description

technical field [0001] The invention relates to a cable inner layer coating material and a production method thereof, in particular to a salt spray test communication cable inner layer coating material and a production method thereof. Background technique [0002] my country is a country with a large ocean, and the coastal area is a large area of ​​saline-alkali land, so the demand for modern communication is particularly strong. However, in the existing communication facilities, since there is no matching coaxial cable dedicated to saline-alkali soil and chemical corrosion resistance, conventional coaxial cables can only be used instead. Conventional coaxial cables cannot adapt to the environment of severe salt spray corrosion in saline-alkali areas, thus often affecting the quality of communication signals and even causing equipment failures. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of...
