Abstract
The invention discloses an environmental-protection flame retardant cable material and a preparation method of the environmental-protection flame retardant cable material. The preparation method comprises the following steps: putting EPDM (Ethylene-Propylene-Diene Monomer) rubber and ethylene-vinylacetate rubber into an internal mixer to be mixed, then putting zinc oxide, antioxidants, lubricants, zinc borate and auxiliary crosslinking agents into the internal mixer to be mixed, then putting carbon black pigment, reactive flame retardants, silane coupling agents and processing aids into the internal mixer to be mixed, finally discharging rubber compounds which are uniformly mixed from the internal mixer after the processing aids and peroxide crosslinking agents are put into the internal mixer to be mixed, packaging into triangle bags through an open mill and carrying out fine grinding, and then performing calendaring through a calender to be prepared into slices, thus obtaining the environmental-protection flame retardant cable material. The environmental-protection flame retardant cable material disclosed by the invention has good low-temperature rolling performance and low-temperature impact properties, can effectively lower the production cost of the environmental-protection flame retardant cable material and solve the problem of roll sticking in the EVM mixing process, has good elasticity and flexibility, excellent transparency and surface glossiness and further has good chemical stability, aging resistance and ozone resistant intensity.
Description
technical field [0001] The invention relates to the technical field of cable materials, in particular to a green and environment-friendly flame-retardant cable material and a preparation method thereof. Background technique [0002] Green and environmentally friendly flame-retardant cables are used in railways, light rails, subways, ships, high-rise buildings and oil platforms, wires for household appliances, low-voltage wires for automobiles, construction machinery, photovoltaic power plants, nuclear power plants, etc. , the current commercialized green flame retardant cable materials in the market mainly include thermoplastic materials and thermosetting materials: commonly used thermoplastics are TPE, TPU, PEEK, TPV, PE, PP, etc. Thermoplastic environmentally friendly flame retardant materials generally have higher Shore hardness and are not suitable Cable products with high flexibility, and materials such as TPE, TPU, PEEK, and TPV have the problem of high prices, and the...
