Dry, obtain modified filler；
(8) being mixed with natural rubber by above-mentioned modified filler, send in banbury, banburying 40-50s at 65-90 DEG C, addition removes
Each raw material beyond sulfur, mixing 10-12 minute, binder removal, it is cooled to less than 50 DEG C, puts in mill, add residue each
Raw material, thin logical 3-5 time, to obtain final product.
The invention have the advantage that the sizing material of the present invention has a good wear resistence:
The edge of stannic oxide/graphene nano sheet contains substantial amounts of carboxylic group, at condensation reagent 1-ethyl-(3-dimethylamino third
Base) carbodiimide hydrochloride effect under, 1-ethyl-(3-dimethylaminopropyl) carbodiimide is first counter with carboxyl to be formed
The 0-acyl isourea intermediate product that can react with amine, N-hydroxy-succinamide plays the effect improving its stability, in the middle of this
Product generates amide with the p-aminobenzene sulfonic acid generation coupling reaction containing primary amine group further, obtains sulfonated graphene, sulphur
The state that functionalized graphene is peeled off in height is evenly distributed in polystyrene microsphere, and the graphite oxide after sulfonation modifying is dilute
Having stronger hydrophilic, improve the dispersibility in its water, the negative charge that sulfonate ion band is stronger simultaneously, in polymerization process
In, the reunion of himself can be effectively prevented, then initiator (potassium peroxydisulfate) first passes through electrostatic interaction and is adsorbed onto sulfonation
The surface of Graphene, then there is polyreaction in trigger monomer on its surface, when, after the many oligomers of deposition, hydrophobicity improves,
And reunite in aqueous phase, hydrophobic polymer then interacts after formation primary nuclei, the styrene list being dissolved in aqueous phase
Body is diffused into continuously in primary nuclei and participates in further polyreaction, and along with the carrying out of polyreaction, growth core is straight
Footpath constantly increases, and the coverage rate that graphite is dilute declines, and Stabilization declines, and now free in aqueous phase sulfonated graphite is dilute stronger
Under π-π the most often acts on, it is adsorbed on polystyrene surface, ultimately forms finely dispersed complex；
The sizing material of the present invention has a good mechanical property:
The present invention is also added into rare earth fiber, and the most surface treated carbon fiber is low due to its surface activity, it is difficult to formed effectively
Interfacial adhesion, therefore composite materials property is very poor, rubber matrix because of frictional heat effect be easy to produce adhesive wear, with
Carbon fiber produce and loosen, crack on interface produces stress and concentrates, and fatigue crack generates, and easily induction composite is further
Abrasion, the present invention uses rare earth modified carbon fiber to be combined in polymeric matrix so that combine tight between carbon fiber and polymeric matrix
Close, in friction process, major part load born by carbon fiber, and load is delivered to carbon fiber, carbon by interface effectively
Fiber effectively acts as the effect of support loads, and composite material surface entirety bears frrction load, and excellent interface cohesion makes it
Coefficient of friction and wear extent are affected little by the frequency that reciprocatingly slides.Rare earth element can occur with C, O, N of carbon fiber surface
Coordination chemistry, and be bonded, when carbon fiber and polystyrene with the organic active group generation chemical coordination in earth solution
Compound tense, can form strong high tenacity interface, thus improve finished product elastomeric material between carbon fiber surface and polystyrene
Mechanical property.
The sizing material of the present invention has fine intensity and weatherability, and combination property is superior, and service life is long.
