Problems solved by technology

[0004] At present, the conventional flame retardant modification method of polyolefin is often to add a lot of inorganic fillers to the base material. The fraction of inorganic fillers exceeds 50%. The addition of a large amount of inorganic fillers often leads to poor physical and mechanical properties and processing performance of cable materials. , so it is necessary to improve the dispersion and compatibility of inorganic fillers, and at the same time enhance the performance of the base material to reduce the deterioration of the base material performance

Abstract

The invention relates to a low-smoke halogen-free flame-retardant glass fiber-enhanced polyolefin cable material. The low-smoke halogen-free flame-retardant glass fiber-enhanced polyolefin cable material is prepared from the following raw materials in parts by weight: 100 parts of polyolefin substrate, 10 to 30 parts of maleic anhydride-modified polyolefin, 40 to 100 parts of filler, 5 to 10 partsof glass fiber, 5 to 10 parts of phosphor-containing flame-retardant agent, 5 to 10 parts of nitrogen-containing flame-retardant agent, 0.1 to 5 parts of epoxy-based silane coupling agent, 2 to 5 parts of direct-chain alkane containing monoamine, and 0.5 to 2 parts of processing additive. The prepared low-smoke halogen-free flame-retardant glass fiber-enhanced polyolefin cable material has good flame-retardant effect, good physical and mechanical properties, and a great application prospect.

Description

technical field [0001] The invention belongs to the technical field of cables, and in particular relates to a low-smoke, halogen-free, flame-retardant glass fiber-reinforced polyolefin cable material. Background technique [0002] With the continuous expansion of industries such as electric power, communications, rail transit, automobiles, and shipbuilding, the demand for wires and cables is also growing rapidly. It can be predicted that the cable market will have huge development potential in the future. [0003] However, at present, there are more and more fires caused by the aging of wires and cables, resulting in the death rate and the suffocation of people caused by the halogenated gas released when the cables are burned. flammability. Therefore, low smoke, halogen-free, flame retardant, and environmental protection have also become the development direction of the wire and cable industry. Among them, the demand for halogen-free low-smoke flame-retardant cable materia...
