Tian Min, Lu et al. deliver《The preparation of blending type wide temperature zone high damping elastomeric material and performance study》One literary composition
In, it is blended using having intensive pending methyl group, the chlorinated scoline of low pole and highly polar nitrile rubber in molecular structure, system
Obtain binary CIIR/NBR blend, due to the pressure after big sterically hindered effect in low pole rubber structure and vulcanization crosslinking
It is wound around, it will increase the internal friction resistance of polar rubber strand activity, lead to molecular chain movement to be obstructed, prepare wide temperature range
Damping material.
In nature, cork is a kind of very excellent material of damping performance, and it is the crust product of cork tree, has
The performances such as good elasticity, sealing, heat-insulated, sound insulation, insulation, wear-resisting, corrosion resistance, protection against the tide, fire prevention, damping, can be used as ground
Plate, bottle stopper and woodwind instrument sealing gasket, packaging and energy absorbing material, heat-barrier material, damping damping material etc., are a kind of many work(
Can natural material.
Therefore, the present invention uses maleic anhydride to be grafted nitrile rubber, then compounding with cork fibrous grafting, on the one hand strengthens
The internal friction resistance of rubber molecular chain activity, the damping capacity of reinforcing material, on the other hand utilize the characteristic of cork fibrous to improve
The sqouynd absorption lowering noise performance of damping material, prepares a kind of nitrile rubber damping material of damping noise reduction excellent performance.
Content of the invention
The invention aims to solving the problems, such as that existing damping material damping, sound absorbing capabilities are not enough, provide a kind of vapour
Automobile-used have nitrile rubber damping material of high flame resistance and preparation method thereof.
A kind of car kits have the nitrile rubber damping material of high flame resistance, are made up of the raw material of following weight portion：Fourth
Nitrile rubber 46-60 part, chlorinated scoline 28-40 part, oxolane 128-165 part, maleic anhydride 46-61 part, benzoyl peroxide
- 4 parts of formyl chloride-1, appropriate amount of ethanol, hydroxide sodium hypophosphite 1-3 part, appropriate dimethylbenzene, cork fibrous 22-34 part, stearic acid 1-2
Part, white carbon black 3-6 part, sulfur 1-2 part, aluminium hydroxide 0.5-1 part, magnesium hydroxide 0.8-1.6 part
Comprise the following steps that：

Mixed solution, is passed through nitrogen protection, is warming up to 60-72 DEG C, and isothermal reaction 6-9 hour goes out graft product with ethanol precipitation afterwards,
With washing with alcohol for several times, the graft product after washing is placed in 38-45 DEG C of vacuum drying oven and dries, that is, obtain MAH-g-NBR,
Standby；
（2）MAH-g-NBR is grafted cork fibrous：
Dimethylbenzene, hydroxide sodium hypophosphite and step is added in the boiling flask equipped with condensing tube（1）The MAH-g- obtaining
NBR, afterwards by the cork fibrous being fully dried immersion mixed solution, controls temperature to react 2-4 hour at 125-140 DEG C,
After the completion of reaction, remove solvent with Soxhlet extractor, dry to constant weight in 95-105 DEG C, obtain final product MAH-g-NBR grafting cork fine
Dimension；
（3）Mixing：
1., under the conditions of 20-30 DEG C, by step（2）The MAH-g-NBR obtaining is grafted cork fibrous, chlorinated scoline, Hard Fat
Sour mix homogeneously is plasticated 13-18 minute on a mill；
2. it is subsequently adding aluminium hydroxide, magnesium hydroxide, white carbon black mixing 20-40 minute, add sulfur mixing afterwards uniformly, be prepared into
Elastomeric compound；
（4）Sulfuration：
By step（3）7-9 hour is stood, on vulcanizing press at 160-190 DEG C after obtained elastomeric compound thin pass-out piece
Hot press moulding vulcanizes 20-40 minute, and a kind of car kits are obtained the nitrile rubber damping material of high flame resistance.
Wherein, described cork fibrous are to be formed with useless industrial source white softwood pulp plate mechanical dissociation and dispersion, its length
Distribution 2mm-3.5mm, width distribution is 34.2 μm -73.1 μm, and length-width ratio is 72.6.
Compared with prior art, the present invention has advantages below：
（1）The present invention carries out graft modification first by maleic anhydride monomer to nitrile rubber, changes the polarity of nitrile rubber, increases
The internal friction resistance of additive polarity nitrile rubber strand activity, leads to molecular chain movement to be obstructed, molecule interchain frictional heat increases,
Damping capacity is more excellent.
（2）There are a lot of gauffers on cork cell wall, can greatly alleviate compression, therefore elastic return is special
Good, in addition the special cellularity of cork fibrous can weaken flat ripple and propagate, and enable in particular to the propagation of noise-reducing sound wave, thus soft
The sound absorption properties of wood utilizes this characteristic of cork fibrous very well in the present invention, be grafted nitrile rubber using maleic anhydride（MAH-g-
NBR）Cork fibrous are carried out with graft modification, improves the compatibility in rubber matrix for the cork fibrous, improve subtracting of damping material
Shake, sqouynd absorption lowering noise performance, can be effectively improved the comfort level of environment inside car, be conducive to the physical and mental health of people.
（3）The decomposition temperature of aluminium hydroxide is 210 DEG C, and the decomposition temperature of magnesium hydroxide is 330 DEG C.Aluminium hydroxide is compound
Decompose during material initiation combustion and play flame retardant effect, with the rising of material surface temperature, magnesium hydroxide also gradually decomposes release
Water of crystallization, the oxide simultaneously producing forms coverlay in material surface, and in solid phase, suppression material burns away, and presses down cigarette effect
Fruit is good.
