Description
Technical Field
The application relates to the technical field of polyolefin composite materials, in particular to a composite material based on bio-based polyethylene and a preparation method thereof.
Background
Low smoke halogen-free polyolefin materials are increasingly being used in the field of wires and cables because of their excellent safety and environmental protection properties. However, most of the prior polyolefin materials are produced by adopting petroleum-based resin as a base material, and the petroleum-based material is derived from petroleum, belongs to non-renewable resources, and can generate a large amount of carbon emission in the petroleum refining process, so that the carbon emission reduction is not realized.
The Chinese patent with application number 2005101197427 proposes a halogen-free flame-retardant radiation cross-linked wire and a preparation method thereof, wherein polyolefin resin is used as a base material, and phosphoric acid derivatives and/or coated red phosphorus, zinc borate, magnesium/aluminum hydroxide, nanoscale transition element oxide, coupling agent and other auxiliary agents are added into the base material to prepare the halogen-free flame-retardant radiation cross-linked wire. The nano powder and vinyl acetate monomer are copolymerized in situ in advance, then are mixed with activated magnesium/aluminum hydroxide, polyolefin resin and other powder, extruded on a double-screw extruder, cooled and granulated, finally are molded on a cable extruder together with a metal core wire, and are irradiated by high-energy rays to prepare halogen-free flame-retardant radiation crosslinked wires and cables. The halogen-free flame-retardant radiation crosslinked wire proposed by the China patent has better comprehensive performance, but a large amount of petroleum-based materials are used, so that the dependence on fossil energy materials is high, the carbon emission reduction is not facilitated, and the sustainable development of resources is also not facilitated. The raw materials of bio-based polyethylene are from renewable sources, but because of the molecular weight and molecular distribution of bio-based materials, which are different from petroleum-based materials, the higher the amount of bio-based material alone, the lower the elongation at break of the composite produced.
Therefore, how to increase the dosage of the bio-based material in the composite material and make the comprehensive performance of the produced composite material meet the expectations, thereby reducing the dependence on fossil energy materials, reducing carbon emission and promoting the sustainable development of resources is a technical problem to be solved.

It is understood that the raw materials used for the bio-based polyethylene are derived from renewable resources (such as sugarcane, non-edible plants, biological fats and oils including kitchen waste oils), so that the dependence on fossil energy sources can be reduced, carbon emission reduction is realized, and sustainable development is selected. The carbon component in the bio-based polyethylene is mainly C14, and the traditional petroleum-based polyethylene does not contain C14, so that the bio-based polyethylene and the petroleum-based polyethylene have poor compatibility due to different carbon components, and the final properties have certain difference. Because of the variability of the molecular weight and molecular distribution of the biobased material from petroleum-based materials, the higher the amount of biobased material alone, the lower the elongation at break of the composite material produced. The ethylene-vinyl acetate copolymer and the ethylene-octene copolymer effectively improve the defects of insufficient heat resistance and toughness of the bio-based polyethylene, and are beneficial to improving the integral processing fluidity. Compared with the traditional compatibilizer POE grafted maleic anhydride, the compatibilizer ethylene-maleic anhydride copolymer has higher content of active groups and fewer free groups, has good heat resistance, relatively low molecular weight and good fluidity, and can better improve the interface adhesion between a resin system and a filler. The interfacial adhesion of the bio-based polyethylene and other components is improved by the synergistic effect of the ethylene-vinyl acetate copolymer with higher polarity and the ethylene-maleic anhydride copolymer with more active functional groups, so that the strength of the composite material is improved, and the good comprehensive performance of the bio-based composite material is ensured.
Thus, the amount of the bio-based material in the composite material is increased and the overall performance of the produced composite material is expected.
