Modified polyethylene cable material with good antioxidant and anti-aging effects and preparation method thereof

Abstract

The invention discloses a modified polyethylene cable material with good antioxidant and anti-aging effects and a preparation method thereof. The material is characterized by being prepared from the following raw materials by weight: 90 to 100 parts of polyethylene, 10 to 15 parts of red phosphorus, 3 to 5 parts of paraffin, 0.5 to 1 part of a silane coupling agent kh570, 15 to 25 parts of nanometer calcium carbonate, 0.8 to 1.6 part of polyvinyl alcohol, 2 to 4 parts of copper powder, 5 to 8 parts of polystyrene resin, 1 to 3 parts of zinc borate, 5 to 10 parts of pentaerythritol stearamide, 2 to 4 parts of molybdenum trioxide, 2 to 3 parts of triisooctyl phosphite, 3 to 5 parts of calcined clay, 1 to 2 parts of polyvinylpyrrolidone and a proper amount of absolute ethanol. The polyethylene cable material prepared by using the method in the invention has the advantages of high bearing strength, strong toughness, good antioxidant and anti-aging effects, high heat stability, environmental protection and low cost, and is worth popularization.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a modified polyethylene cable material with good anti-oxidation and anti-aging effects and a preparation method thereof. Background technique [0002] Communication and electric power are the key points of national construction. No matter where the development is, the construction of communication and electric power always takes the lead, so the development of communication and electric power is very fast. The development of communication and electric power industry requires the cooperation of various aspects, among which the cable material is one aspect. The general-purpose wire and cable covering materials are mainly plastic and rubber, and the thermoplastic materials for wire and cable only need to have polyvinyl chloride, polyethylene, and polypropylene. , fluoroplastics, chlorinated polyethers and polyamides, among which polyethylene and polyvinyl chloride are widely used.

Problems solved by technology

Polyethylene is a large variety of thermoplastics. It has the characteristics of light weight, non-toxicity, and excellent chemical corrosion resistance. However, polyethylene has a very low oxygen index and is a flammable material. Polyethylene will produce serious melting when it is burned. Dripping behavior, which brings great difficulties to flame retardancy. In addition to being flammable, polyethylene has high volume resistivity and surface resistivity, which makes it very difficult to charge static electricity during processing and use. Difficult to eliminate, the above two shortcomings have brought great safety hazards to the use of polyethylene and reduced the scope of use
