preparation example Construction

[0052] The preparation method of conductive polybutene as described above, described method comprises the steps:

[0053] The polybutene, ethylene propylene copolymer, conductive carbon black and carbon nanotubes are mixed for internal mixing and molding, and then extruded to obtain conductive polybutene.

[0054] 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 polybutene and ethylene propylene copolymer, so as to realize normal extrusion molding.

[0055] In a preferred embodiment of the present invention, conduction carbon black and carbon nanotube are heated to remove moisture, then mix with polybutene and ethylene propylene copolymer, further preferably conduction carbon black and carbon nanotube are placed in high It is heat...

Abstract

The embodiment of the invention discloses conductive polybutylene, which is mainly prepared from the following raw materials in parts by weight: 60 to 80 parts of polybutylene, 5 to 15 parts of ethylene-propylene polymers, 1 to 5 parts of carbon nanometer tubes and 15 to 25 parts of conductive carbon black. After an inner liner prepared from the conductive polybutylene is applied to a chemical rawmaterial barrel, in the use process, chemical raw materials are in direct contact with the inner liner and is not in direct contact with the side wall of the chemical raw material barrel, so that thedirect pollution on the chemical raw material barrel is avoided; the treatment cost of dangerous waste can be greatly reduced.

Description

technical field [0001] The invention relates to the field of polyolefins, in particular to a conductive polybutene, 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 impac...
