The invention have the advantage that the sizing material of the present invention has a good wear resistence:
nullThe edge of stannic oxide/graphene nano sheet contains substantial amounts of carboxylic group,Under the effect of condensation reagent 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride,1-ethyl-(3-dimethylaminopropyl) carbodiimide is first counter with carboxyl forms the 0-acyl isourea intermediate product that can react with amine,N-hydroxy-succinamide plays the effect improving its stability，This intermediate product generates amide with the p-aminobenzene sulfonic acid generation coupling reaction containing primary amine group further，Obtain sulfonated graphene，The state that sulfonated graphene is peeled off in height is evenly distributed in polystyrene microsphere，Graphite oxide after sulfonation modifying is dilute has stronger hydrophilic，Improve the dispersibility in its water，The negative charge that sulfonate ion band is stronger simultaneously，In the course of the polymerization process,The reunion of himself can be effectively prevented，Then initiator (potassium peroxydisulfate) first passes through electrostatic interaction and is adsorbed onto the surface of sulfonated 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 monomer being dissolved in aqueous phase is diffused into continuously in primary nuclei and participates in further polyreaction，And along with the carrying out of polyreaction，Growth nuclear diameter constantly increases，The coverage rate that graphite is dilute declines，Stabilization declines，Now free in aqueous phase sulfonated graphite is dilute under stronger π-π the most often acts on，It is adsorbed on polystyrene surface，Ultimately form 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, the most surface treated carbon fiber is low due to its surface activity, it is difficult to form effective interfacial adhesion, therefore composite materials property is very poor, rubber matrix is easy to produce adhesive wear because of frictional heat effect, carbon fiber produces and loosens therewith, crack on interface produces stress and concentrates, fatigue crack generates, easily induction composite is further worn out, the present invention uses rare earth modified carbon fiber to be combined in polymeric matrix, make to be tightly combined between carbon fiber and polymeric matrix, in friction process, major part load born by carbon fiber, and load is delivered to carbon fiber by interface effectively, carbon fiber effectively acts as the effect of support loads, composite material surface entirety bears frrction load, excellent interface cohesion makes its coefficient of friction and wear extent be affected little by the frequency that reciprocatingly slides.Rare earth element can occur coordination chemistry with C, O, N of carbon fiber surface, and be bonded with the organic active group generation chemical coordination in earth solution, when carbon fiber and polystyrene compound tense, strong high tenacity interface can be formed between carbon fiber surface and polystyrene, thus improve the mechanical property of finished product elastomeric material.
Present invention adds the multiple auxiliary agents such as zinc hydroxyl stannate, Pulvis Talci, decabromodiphenyl oxide, aluminium-magnesium silicate, effectively raise the fire line of finished product sizing material, improve security performance.
