Problems solved by technology

Although the insulating material for medium-voltage rubber insulated cables has high flexibility and good electrical properties, the insulating material is mainly made of different grades of EPDM rubber, and the content of EPDM rubber is increased (up to 61%) to achieve high flexibility of the insulating material. , low hardness, this method leads to high cost of insulating materials, and the Shore hardness of the insulating material is up to 80, which is difficult to install and poor in construction

Abstract

The invention discloses an anti-cracking anti-corrosion cable material and a preparation method thereof, and relates to the field of a cable material. The cable material is prepared from the followingraw materials in parts by weight: 50 to 60 parts of high density polyethylene, 18 to 25 parts of ethylene-vinyl acetate copolymers, 3 to 8 parts of maleic anhydride grafted polyethylene, 5 to 10 parts of modified polytetrafluoroethylene particles, 5 to 10 parts of nanometer titanium dioxide, 22 to 27 parts of aluminum hydroxide, 3 to 8 parts of chitin, 1.8 to 4.2 parts of plasticizers and 1.6 to3.5 parts of antioxidizers. The cable material has the advantages that through the cooperated matching effect between the raw materials, good heat resistance, weather resistance and anti-corrosion performance can be realized; the mechanical toughness and the anti-stretching performance are excellent; the durability and the fireproof performance are high; the use safety is high; the preparation method is simple; the operation and the production are easy.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to a high temperature resistant cable material and a preparation method thereof. Background technique [0002] Wire and cable is a wire product used to transmit electric (magnetic) energy, information and realize electromagnetic energy conversion. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting lines, household appliances, etc. Plastics for wire and cable insulation and sheathing are commonly known as cable materials, including rubber, plastic, nylon and other varieties. [0003] With the improvement of people's safety awareness, people have higher and higher requirements for the flame retardancy and fire resistance of wire and cable. In many large-scale fire accidents in public places, the cause of most of the deaths is suffocation due to inhalation of corrosive and toxic smoke gases released from burning wires and cables ...
