Abstract
The invention relates to the technical field of nano carbon material pelletizing and in particular to a nano carbon material compression pelletizing device for rubber and a process method. The compression pelletizing device is internally of an upright hollow cylindrical structure with a compression cavity, and comprises a compression cavity, a hydraulic device, a feeding control device, a filtering device, a vacuum exhaust device, a back blowing device, a discharge device and a pelletizing device. The process method of compression pelletizing comprises the following steps: (1) uniformly mixinga nano carbon material with a rubber formula aid filler; (2) putting mixed materials into the inner cavity of the device; (3) performing vacuuming; (4) compacting the mixed materials; (5) dischargingand pelletizing compressed materials; (6) discharging materials; (7) performing back blowing; and (8) repeating the process, so as to achieve continuous compression pelletizing. A part of materials of a formula of rubber self are adopted to bond the nano carbon material, a solvent does not need to be removed at a later stage, the compact density of the nano carbon material pelletized by using thedevice and the method is remarkably increased, and continuous operation and high efficiency can be achieved.
Description
technical field [0001] The invention relates to the technical field of nano-carbon material granulation, in particular to a nano-carbon material compression granulation device and process method for rubber. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes have excellent physical and mechanical properties. They are mainly coaxial circular tubes with several to dozens of layers of carbon atoms arranged in a hexagonal shape. It has a very large aspect ratio, the diameter is usually between 1-100nm, and the length is several microns to hundreds of microns. It is precisely because of its large aspect ratio that carbon nanotubes perform very well in terms of mechanics, electricity, and electrical and thermal conductivity. Due to its excellent properties, carbon nanotubes have broad and potential application prospects in many fields such as catalyst supports, rubber-plastic composite materials, electrochemical materials, and photoelectric sensing. ...
