Abstract

The embodiment of the invention relates to the technical field of cable materials, in particular to a cable material and a preparation method thereof. The cable material is prepared from, by weight, 50-70 parts of polyvinyl chloride resin, 5-10 parts of stabilizer, 15-25 parts of inorganic filler, 23-35 parts of plasticizer, 0.1-1 part of lubricant, 1-5 parts of flame retardant, 0.1-1 part of toner, 3-5 parts of flexibilizer, 1-3 parts of anti-dripping agent and 1-2 parts of antioxidant; wherein the inorganic filler comprises a first filler for improving the peel strength of the cable materialand a second filler for improving the electrical property of the cable material, and the plasticizer at least comprises an epoxy oil plasticizer and a benzene plasticizer. The cable material can satisfy related requirements of European standards, and has high tensile strength, elongation, good flame retardance and the like.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a cable material and a preparation method thereof. Background technique [0002] Plastics for wire and cable insulation and sheathing are commonly known as cable materials. Since wires and cables usually need to be coated inside the insulating layer processed from cable materials, important properties such as mechanical properties, electrical properties, and combustion properties of cable materials must be met. Certain standards. At present, many countries and regions in the world have their own inspection standards, such as Chinese national standards, European standards, international standards, American standards, Japanese standards and so on. Among these standards, European standards have very high requirements on many indicators, including: tensile strength, elongation, aging characteristics, flame retardant characteristics and other indicators of cable materials. It...
