Description

Technical field:

[0001] The invention relates to the field of a halogen-free flame-retardant wire and cable sheathing material, in particular to a flexible halogen-free flame-retardant polyphenylene ether wire and cable sheathing material and a preparation method thereof. Background technique:

[0002] Wires and cables are widely used in the transmission of energy and information. Traditional polyvinyl chloride (PVC) wire and cable sheathing materials are very easy to catch fire due to excessive heat generation of the line during use, causing fires. And, PVC cable material produces a large amount of poisonous gas and smog when burning, seriously endangers people's life and property safety. The hydrogen chloride gas released when the PVC cable material is burned can also cause corrosion of equipment, thereby causing "secondary pollution". Secondly, the processing fluidity and thermal stability of PVC resin itself are poor, so plasticizers and stabilizers need to be added to ...
