Problems solved by technology

[0004] If nanometer and submicron carbon spheres with spherical characteristics are selected as auxiliary lubricants, it will help improve the rolling lubrication ability. The role of the nanospheres is similar to that of "balls". And improve the area where carbon nanospheres cannot be filled, so the comprehensive lubrication characteristics can be improved, but the existing technology has not yet

Embodiment 1

[0022] Such as figure 1 , figure 2 As shown, a high-lubricity graphene / carbon nanosphere composite engineering plastic and its preparation method mainly include a preparation device and a preparation method.

[0023] The preparation device includes a high-temperature and high-pressure reaction kettle 1 , a high-temperature treatment furnace 2 , a stirrer 3 and a dryer 4 . Put plastics such as polyethylene into a high-temperature and high-pressure reactor 1 at about 700°C, and undergo high-temperature and high-pressure gas phase decomposition to obtain carbon spheres with a size on the order of nanometers or submicrons, and then put these carbon spheres into a room with an inert gas at a temperature above 2000°C high-temperature treatment furnace 2 to obtain nano-carbon spheres with high degree of graphitization and high hardness, and then put these nano-carbon spheres into the stirrer 3, and put graphene at the same time. After the two are mixed in proportion, they are mixed...

Embodiment 2

[0032] Considering the wide range of applications, the mixed liquid phase after the above stirring is not dried, but added to the silicone oil series to form a paste, and semi-solid composite lubricants with different thicknesses are made according to the proportion of the added silicone oil. .

Abstract

The invention discloses a graphene / nano carbon sphere compound engineering plastic with high lubricity and a preparation method thereof and mainly relates to a preparation device and the preparation method. The preparation device is characterized by comprising a high-temperature high-pressure reactor, a high-temperature processing furnace, an agitator and a dryer. The preparation method comprises the following steps: carrying out phase decomposing on a plastics raw material at high temperature and high pressure to obtain nano carbon spheres, putting the nano carbon spheres and graphene into the agitator, stirring and then putting a mixed liquid phase into the dryer, and drying to obtain a solid lubricant. The engineering plastic has the beneficial effects of not only having wear resistance and antifriction performance but playing roles in sealing and damping for the engineering plastic with hard nano carbon spheres, making a lubricating system of equipment (a product) simple, being convenient to maintain and manage, saving operating cost of the lubricating system, and having significance in filling the blank of lubricating materials badly needed in industries and national defense.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials and functional material chemistry, and relates to a graphene / nano carbon sphere composite material. Background technique [0002] Graphene is a single-layer carbon atom surface material exfoliated from graphite materials. It is a two-dimensional structure of carbon. It is obtained by decomposing polypropylene or polyethylene under high temperature and high pressure. , is also a two-dimensional structure, all of which belong to the compound hexagonal lattice, and can be compounded with each other. After the compound liquid phase is volatilized and dried, new materials can be obtained, so that graphene is wrapped on the surface of carbon spheres, and graphene acts like a "lubricating oil". oil", and the high-hardness micron carbon balls act like "steel balls", making this type of solid lubricant have the greatest lubricating effect. [0003] Among the solid lubricants that have been reported,...
