The preparation method of the bag coating compound of a kind of described resin rubber composite print rubber roll, comprises the following steps:
(1) by dilute for above-mentioned graphite oxide DMF joining its weight 50-60 times, supersound process 20-30
Minute, add 1-ethyl-(3-dimethylaminopropyl) carbodiimide hydrochloride, N-hydroxy-succinamide, stirring mixing
1.7-2 hour, adding p-aminobenzene sulfonic acid, under room temperature, stirring reaction 23-24 hour, washes with water 3-4 time, the most ultrasonic 10-
15 minutes, obtain sulfonated graphite dilute；
(2) sulfonated graphite is dilute, styrene mixing, the deionized water of addition compound weight 40-50%, ultrasonic 10-15 minute,
Obtain sulfonation emulsion；
(3) above-mentioned thiol-butyl tin is joined in the deionized water of its weight 10-17 times, stir, add carboxymethyl fine
Dimension element, stirs, for fiber solution；
(4) above-mentioned ethylenediaminetetraacetic acid is joined in the ammonia of 20-25%, add lanthanum chloride, insulated and stirred 20-at 60-70 DEG C
30 minutes, adding carbon fiber, heat-insulation soaking 1-2 hour, add above-mentioned fiber solution, 70-100 rev/min is stirred 10-15 minute,
Obtain rare earth modified carbon fiber solution；
(5) in above-mentioned sulfonation emulsion, add potassium peroxydisulfate, stir, under nitrogen protection, 70-80 DEG C of insulated and stirred 5-6
Hour, it is cooled to room temperature, adds above-mentioned rare earth modified carbon fiber solution, supersound process 10-15 minute, sucking filtration, remove filtrate,
Filtering residue；
(6) above-mentioned gum dammar is joined in the dehydrated alcohol of its weight 2-3 times, stir, add linoleic acid, send into
In the oil bath of 100-120 DEG C, insulated and stirred 20-30 minute, discharging, add above-mentioned filtering residue, beta-hydroxy alkylamide, stirring is to often
Temperature, is distilled off ethanol, for premix material；
(7) above-mentioned premix material is mixed with natural rubber, sends in banbury, banburying 40-50s at 65-90 DEG C, add except
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 former
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.
Present invention adds gum dammar, effectively raise the weatherability of finished product sizing material, further improve between each raw material
The compatibility, improves the stability of finished product.
