Environment-friendly cable insulation material and preparation method thereof

Abstract

The invention discloses an environment-friendly cable insulation material and a preparation method thereof. The cable insulation material is prepared from the following raw material components: PVC resin, a plasticizer, a flame retardant, a heat stabilizer, an antioxidant, a processing aid, a lubricant, a filler, a colorant and the like. The preparation method comprises the steps of material mixing, plastication, extrusion, packaging and the like. Industrial production can be carried out through cable insulation material complete equipment; the design is reasonable, a composite flame retardantis used for retarding flame; the solid-phase flame-retardant effects of efficient heat insulation and oxygen insulation are achieved; the heat stabilizer is an organic tin stabilizer, so that the heat resistance of the cable insulation material can be greatly optimized, the cable insulation material is resistant to vulcanization pollution, safe and environment-friendly, and the cable insulation material prepared by the preparation method is outstanding in insulation performance and mechanical property and can be industrially produced in batch by complete equipment.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to an environment-friendly cable insulating material and a preparation method thereof. Background technique [0002] Cable insulation materials and sheath materials are commonly known as cable materials, including rubber, resin, nylon, quantity and other varieties. The function of the cable insulation material is to protect the cable conductors, which has good insulation and mechanical properties, and also has certain flame retardant and heat resistance properties.

Problems solved by technology

[0003] With the progress of society and the deepening of the concept of environmental protection, the requirements for non-halogen and non-toxic cable insulation materials are getting higher and higher. The old-fashioned cable insulation materials with poisonous halogen properties are gradually eliminated, and environmentally friendly cable insulation materials are gradually being developed. , but there are also certain problems. By using environmentally friendly materials to replace the toxic components in the old-fashioned cable insulation materials, the performance of the cable insulation materials will be greatly reduced. Therefore, under the premise of ensuring or even improving the performance of the cable insulation materials, Replacing suitable environmentally friendly materials is an important direction for the development of cable insulation materials. At the same time, on the premise of ensuring environmental protection, increasing production and carrying out industrialized production are also top priorities.
