preparation example Construction

[0048] The preparation method of conductive polyethylene as described above, said method comprises the steps of:

[0049] Mix polyethylene, ethylene propylene copolymer, conductive carbon black and graphene for banbury molding, and then extrude to obtain conductive polyethylene.

[0050]In the present invention, the internal mixing forming can be realized by an internal mixer, for example, by a HAAKE internal mixer. The extrusion can be achieved by means of a twin-screw extruder or a single-screw extruder. The extrusion temperature can be determined by the melting temperature of polyethylene and ethylene-propylene copolymer, so as to realize normal extrusion molding.

[0051] In a preferred embodiment of the present invention, conductive carbon black and graphene are heated to remove moisture, and then mixed with polyethylene and ethylene propylene copolymer, and further preferably conductive carbon black and graphene are put into a high mixer It is heated to remove moisture...

Abstract

The embodiment of the invention discloses a conductive polyethylene. The conductive polyethylene is mainly prepared from, by weight, 60-80 parts of polyethylene, 5-15 parts of an ethylene-propylene copolymer, 1-5 parts of graphene and 15-25 parts of conductive carbon black. After an inner liner prepared from the conductive polyethylene is used in a chemical raw material barrel, the chemical raw material is in direct contact with the inner liner and is not in direct contact with the sidewall of the chemical raw material barrel in the use process in order to avoid the direct pollution of the chemical raw material barrel, so the treatment cost of hazardous wastes is greatly reduced.

Description

technical field [0001] The invention relates to the field of polyolefins, in particular to a conductive polyethylene, a preparation method and an application thereof. Background technique [0002] The industrial production process will produce a large number of discarded chemical raw material barrels, such as waste paint barrels, dye barrels, ink barrels, waste engine oil barrels, resin waste iron barrels, etc., which are all hazardous wastes. [0003] Due to the serious pollution and potential serious impact of hazardous waste, it is necessary to properly dispose of hazardous waste. At present, hazardous waste treatment enterprises in my country need to have certain qualifications. The threshold of hazardous waste treatment technology is relatively high, the treatment cost is high, and the treatment capacity is limited. The huge production of hazardous waste leads to a large market gap, and the treatment rate of hazardous waste is low. The environment has huge potential imp...
