Problems solved by technology

The currently reported low-smoke halogen-free flame-retardant cable materials are mainly filled with a large amount of inorganic flame retardants to meet the flame-retardant requirements, such as Chinese patents CN107177078A and CN104017261B. The physical and mechanical properties of the cable material are severely reduced and the efficiency of the flame retardant performance is limited.

Abstract

The invention discloses a flame-retardant cable material. The flame-retardant cable material comprises the following raw materials in parts by weight: 60-85 parts of polypropylene, 10-35 parts of SEBSresin, 2-8 parts of LDPE, 5-15 parts of maleic anhydride grafted polypropylene, 0.2-1.0 part of pentaerythritol stearate, 1-6 parts of magnesium stearate, 20-35 parts of light calcium carbonate, 15-25 parts of magnesium hydroxide, 5-10 parts of modified hydrotalcite, and 10-20 parts of modified ammonium polyphosphate. The prepared cable material has good mechanical properties and flame-retardantproperties through synergistic reinforcement and flame retardancy.

Description

technical field [0001] The invention relates to the technical field of wires and cables, in particular to a flame-retardant cable material. Background technique [0002] With the development of industrial construction and the continuous upgrading of communication facilities and power grid transformation, the demand for wire and cable is increasing day by day. Traditional wire and cable materials use cross-linked polyethylene as an insulating material. As a thermosetting plastic, it cannot be recycled effectively, resulting in waste of resources and environmental pollution. As a piece of thermoplastic, polypropylene is relatively cheap, easy to form and process, and can be effectively recycled. It can be used as an environmentally friendly wire and cable insulation material. However, polypropylene materials have problems such as poor toughness, high modulus, and high brittleness at low temperatures, and cannot be directly used as wire and cable materials. Therefore, it is ne...
