Mitron dispersant special and preparation method thereof, and the CNT dispersion pulp made with this dispersant and preparation method thereof.
Background technology
Nano-carbon material because possessing various prominent physics, chemical property cause the broad interest of paint field.Nanometer
Material with carbon element has high-specific surface area, can form network structure when coating is dried, thus strengthen the adsorption of coating and substrate,
Make coating finer and close, improve the coating adhesive force to base material, meanwhile, be favorably improved the impact resistance of coating, rub resistance
Performance, heat conductivity, electric conductivity, weatherability and antiseptic property, and there is scratch resistance and slightly scratch self-repair function, it is used for making
The conductive primer of standby inner and outer decorative parts of automobile electrostatic spraying has superiority very much;Static conductive coating, antistatic coating application in
Sample has good performance.CNT (CNT) is one type nano-carbon material, has high thermal conductivity and high-specific surface area,
Can be sufficient filling with in the coating, increasing coating cooling surface area, it is possible to effectively reduce body surface and internal temperature, simultaneously by
Yu Qiguang, thermally and chemically stability are high, all can use at various extreme environments, can be used for LED heat radiation coating, industrial equipment dissipates
Hot coating, auto parts and components heat radiation coating etc..

The problem of coating film forming matter mixing, these nano materials only have well to disperse and be uniformly distributed in coating system just can fill
Its effect is waved in distribution.Nano-carbon material and fluoropolymer resin complex method substantially have three kinds: physical blending, chemical modification, in situ
Polymerization, thus realize the stable dispersion of CNT and the performance of features thereof.Physical blending is not destroying nano-carbon material
On the premise of structure, rely on physical action to be directly realized by the mixing of CNT and matrix resin, can pass through solution, emulsion,
Melting method is carried out, and is realized by the external force such as mechanical agitation or supersonic oscillations, typically requires nano material before being blended
It is modified improving and the compatibility of matrix resin, is the simplest, common method, but there is also difficult control, dispersion all
The problems such as even property is the best.Chemical modification method is in CNT and graphenic surface functionalization (hydroxyl or amino etc.), then altogether
The valency upper matrix polymer of grafting or the polymer segment compatible with matrix resin.Situ aggregation method is to add in monomer polymerization process
Entering the CNT that surface is the most processed, after mix homogeneously, the polymerization of trigger monomer forms composite again.
Incompatible due to CNT and matrix resin, it is effectively multiple that simple physical blending process is difficult to make both obtain
Closing, using effect is also had a greatly reduced quality, and usually in order to improve the compatibility of CNT and resin, needs to carry out with to CNT
Surface processes, and such as uses strong acid oxidation so that carbon nano tube surface forms the functional groups such as hydroxyl.Chemical modification method and original position are poly-
Legal is all that this process is all to CNT so that carbon nano tube surface to carry out chemical treatment and the method being modified as basis
Structure causes a certain degree of destruction, and therefore, pyroelecthc properties and mechanical performance to CNT all can cause damage, and cause
Usefulness declines.
Therefore, develop the method for the non-conjugated functionalization of a kind of CNT and realize carbon nanomaterial and high molecular polymer is multiple
Desirable justice is the most great.Non-conjugated functionalization by polymer molecule and the Van der Waals force of carbon nano tube surface, π π, CH π and
Electrostatic interaction realizes, and does not affect the structure of nanotube, and therefore the electrical characteristics of CNT and mechanical property are all without being subject to
To impact.
