The present invention relates to the technical field of automobile new material special process manufacture more particularly to a kind of truck drive shaft are anti-
It splits, anti-aging terminal pad sizing material.
Background technique
Transmission process is not smoothly, to need to drop destruction of the stress concentration to transmission shaft, transmission shaft intermediate supports rubber
Glue is named as elastic rubber cushion, if elastic rubber cushion tearing occurs, deforms it is necessary to replace.Excellent terminal pad
It can reduce vibration, slow down resonance, protect transmission shaft.
Being kneaded is exactly to be mixed the raw rubber after plasticating and compounding agent by the mechanical agitation of rubber mixing machine, keeps compounding agent complete
It is evenly dispersed in raw rubber entirely.Mixing is one of the important procedure produced during rubber product, if be kneaded unevenly,
The effect of rubber and compounding agent is not in full use, and influences the service performance of rubber product.Mechanical dry pigmentation is by lignin
It is mixed with butadiene-styrene rubber with rubber mixing machine;Mechanical wet mixing method is that the lignin for being 30%~50% by water content borrows refining with butadiene-styrene rubber
Glue machine is mixed;Coprecipitated technique is that first lignin is dissolved in lye, and the rubber latex being ready for is added, and stirring can fit
Mixture is added in acid solution after heating, is stirred continuously, is allowed to neutralize, filtering precipitate, is washed, it is dry.Pass through mixing
Technique is scattered in lignin in rubber matrix, on the oxygen atom in the groups such as methoxyl group, hydroxyl and carbonyl in lignin not
Share electron pair energy and metal ion form lignin-metallo-chelate in a manner of coordinate bond, and such chelate is existing hydrophobic
Property has hydrophily again, can improve the compatibility between filler and rubber well.And metal enhancing element is usually embedded into rubber
In glue product, metallic element is contained if in rubber tyre as structural reinforcement material, therefore metal can be enhanced in lignin
Plant fiber and rubber are improved due to joined the lignin that there is high-affinity to plant fiber with the bond properties of rubber
Bonding force between glue keeps plant fiber entangled with one another together, enhances the breaking strength of rubber.
Carbon black is widely used in rubber industry, is in addition to rubber external application itself as a kind of excellent rubber-reinforcing filler
Amount accounts for deputy component, and in rubber size process, calendering process is most important, plays and eats filler and other compositions
Enter and disperse effect in the polymer, traditional handicraft is the batch melting or continuous mixed by filler and solid rubber or particle
It refines to realize, i.e., dry method is kneaded, and due to the biggish table surface area of carbon black particle and negative distance, is easily reunited, therefore be difficult
It is even to be dispersed in polymer body, than outer, traditional dry method the disadvantages of there are also highly energy-consuming, high pollution, severe working environments.
Present invention mainly solves plant fibers to dissipate unevenly in rubber product, is easy to happen reunion and influences finished product rubber
The performance of glue product.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of pair of reed fiber particles to be modified, and improves it in rubber
In degree of divergence, so that lignin is played the role of perfect reinforced rubber.
The present invention is realized by following technological means solves above-mentioned technical problem:
A kind of truck drive shaft cracking resistance, anti-aging terminal pad sizing material,
Sizing material of the invention includes basic material: natural rubber latex 100~120, styrene-butadiene latex 10~15, polyvinyl chloride
5~10, N550 carbon black 50~60, N744 carbon black 10~15, indirect process zinc oxide 4~8, anti-aging agent RD 1~2, anti-scorching agent CTP
0.2~0.5, stearic acid 1~2, antioxidant 4010NA 2~3, flowing dispersing agent RL-12 3~5, protection wax RW287 2~3,
Insoluble sulfur IS-60 2~4, Vulcanization accelerator TMTD 1~2, diphenylguanidine 0.2~0.6, plasticizer glycerine 1~2;Addition changes
Property reed fiber particle is made.
Modification for reed fiber particle the following steps are included:
Step 1: first rolling reed straw to disintegrating slag, it is dense that quality then is put into the ratio of solid-liquid ratio 1:50~100
Degree is in the NaOH aqueous solution of 10g/L, and heating and thermal insulation continues 100~150min to 80~90 DEG C, then pulls stalk slag out, is put into
It rinses 3~5 times in clear water, is dried in 40 DEG C of baking ovens;Obtain rough surface and the better fibre of compatibility.By plant fibre
Dimension is added the functional characteristic for improving rubber product into rubber product and has precedent, though obtaining certain effect, effect is not
It is optimal.It is an object of the invention to improve peptizaiton of the plant fiber in rubber product, the reunion for changing fiber is existing
As.By microexamination it can be found that: observed from the appearance without pretreated fiber cylindrical, surface is smooth, distortion
Degree is low;And will appear irregular etching trace in the fiber after Alkaline pretreatment impregnates, it is primarily due to lye and goes
In addition to some surface waxes and pectin in reed straw, the surface of fiber is made to become coarse, and pectin is also that composition plant is thin
The important composition ingredient of cell wall, being easy, which loses plant cell, protects and is exposed under the environmental condition of " danger ".The knot of reed
Structure tissue becomes loose, occurs completely different structure by microexamination surface, and the surface appearance of reed straw is crude, by
Being destroyed in the protective wax of plant surface causes, while the surface polarity of internal fiber element is exposed, and makes reed surface
Fiber there is twisted phenomena.Wax, pectin and the hemicellulose on the soda boiling removable fibrous surface through appropriate mass concentration.Half
Cellulose is easily hydrolyzed by lye and is removed, and lignin is a kind of higher substance of relative molecular mass, the solubility in lye
Less.
Then the reed straw after drying is ground, crosses the pulvis of 80~120 meshes, microcosmic angle is examined
It examines, reed is ground into graininess, due to the preprocessing process of lye, improve its compatibility with rubber latex, but according to
Perfect raising rubber product toughness, crack resistence and age inhibiting effect cannot be so played, since rubber product can be improved in fiber
The key substance of performance is lignin, in lignin containing more active group for example aromatic radical, alcoholic extract hydroxyl group, carboxyl, methoxyl group,
Conjugated double bond etc. is easier that a plurality of types of react occurs between rubber and inorganic filler.Lignin can occur with rubber
The reactions such as grafting, crosslinking, and hydroxyl reactive group can form fragrant hydrogen with the pi-electron cloud of conjugated double bond in rubber in lignin
Key.Unshared electron pair energy and metal ion are in a manner of coordinate bond on oxygen atom in the groups such as methoxyl group, hydroxyl and carbonyl
Lignin-metallo-chelate is formed, and constructs the network structure of rubber cross using the reactivity of lignin molecule, thus
Lignin is set to play the role of reinforced rubber.
Step 2: the processing of cellulose complex enzyme is carried out to the reed pulvis of first step preparation, the leaching of lye in the first step
Bubble only destroys the wax and pectic substance of plant tissue, causes the cuticula of cell and primary cell wall to be dissolved, not
There is large-scale removing cellulose, so being mainly lignin and cellulose in reed particle obtained;Utilize the work of enzyme preparation
Most of cellulose can be effectively removed with specificity, causes the particle of reed to present porous latticed, retains most
Lignin;Improve surface area simultaneously, by the distilled water mixed diluting of reed pulvis and 10~15 times of parts by weight, then addition 5~
The cellulase preparation of 8FPU/g, 1.5~2.0h of oscillation hydrolysis, boils mixed liquor pair immediately after the completion under 50 DEG C of constant temperatures
5~10min of enzyme-deactivating is washed with distilled water 2~3 times.
But pass through multiple repetition and test discovery: the reed particle pair of the lignin main component with fenestral fabric
Uneven in the performance enhancement effect of rubber product or unobvious or rubber intensity locations, this is for being mainly used for vapour
It is very unfavorable for the rubber of vehicle transmission shaft connection plate, if the position of enhancing is uneven, for integrated connection disk, as long as having
One position weakness, which causes to crack, will scrap the use of entire terminal pad.By multi-faceted textual criticism: being the discovery that due in reed
Very strong polarity is shown containing great amount of hydroxy group, causes reed easily to absorb water and generates agglomeration, leads to itself and nonpolarity heat
Section poor compatibility between plastic resin, has seriously affected the overall performance of composite material, also result in the performance at some positions compared with
It is good, and there is no enhance for the performance at some positions.
Step 3: improve dispersion performance of the reed particle in rubber latex, at the same utmostly improve reed particle with
The contact compatibility of rubber, so adding intermediary between reed fiber and rubber --- carbon black, carbon black is in rubber product
Originally essential component, addition manner here are different;The phenomenon that reuniting similar to reed fiber, carbon black is in rubber glue
Also agglomeration can occur in cream, hydrophilic carbon black is made using ammonium persulfate as modifying agent in the present invention, and carbon black is pressed feed liquid
It is mixed than the ratio of 1:10~15 with 30% ammonium persulfate aqueous solution, the reed fiber particle of second step preparation, ultrasound is added
Disperse 80~120min, soaking and water washing 2~3 times after filtering carry out Surface Oxidation Modification to carbon black using ammonium persulfate, increase
Carbon blacksurface hydrophily oxygen-containing functional group, it is suppressed that reunite between particle, it is small to obtain partial size, and dispersibility and stability in water
Greatly improve modified carbon black.It is finally dried to obtain modified carbon black, modified carbon black is carried out by IR Characterization
Paired observation discovery, the partial size of original carbon black are 155nm, modified carbon black average grain diameter 110nm, amount of decrease reach 40% with
On, it is clear that since the hydrophilic radical of modified carbon blacksurface increases, carbon blacksurface agglomeration power is enhanced, carbon black grain is reduced
Subbase group agglomeration obtains finely dispersed carbon black aqueous solution.Carbon black after peroxidating, Surface oxygen-containing groups increase, charcoal
Active force increases between black track producing particle, it is suppressed that the reunion of carbon black increases the dispersing agent dispersion stabilization of carbon black in aqueous solution.
Simultaneously because the effect of ultrasonic activation, enters the carbon black fine particle of a part in latticed reed fiber, promotees
Weaken the agglomeration of reed fiber particle.The involvement of carbon black reduces the polarity of reed, increases reed fiber and resin
Contact area, improve the interface binding power between resin, promoted in the ability of terms of mechanics.The polarity of fiber molecule
It reduces, interaction force reduces, and strand flexibility improves, and strand is weakened by rotational resistance, dispersion of the fiber in resin
Property increase, molecular motion become it is relatively easy, improve the mobility of composite material.
Reed fiber surface is smooth, and the section between resin is clear, and reed fiber not only compare in resin by a point dispersion
Uniformly, do not occur the phenomenon that largely reuniting, and reed fiber is embedded in resin, and its surface has one layer of attachment, sentences
Disconnected should be the carbon black fine particle adsorbed in fenestral fabric;Fiber is set firmly to be bonded on resin, these attachments can
To form sticky point as the connection " bridge " between reed and matrix resin, so that the interface enhanced between reed and resin is viscous
With joint efforts.
Glycerine, which is added, can improve dispersibility of the lignin in butadiene-styrene rubber matrix, be increased using glycerine as lignin
Agent is moulded, can further improve lignin/rubber composite material morphosis, and then lead to the improvement of mechanical property.
The present invention has the advantages that adding modified reed fiber particle, the holey reed fiber particle of preparation has
The lignin of the overwhelming majority constitutes structure, contains more active group such as aromatic radical, alcoholic extract hydroxyl group, carboxyl, methoxy in lignin
Base, conjugated double bond etc., be easier to occur between rubber and inorganic filler it is a plurality of types of react, lignin can be sent out with rubber
The reactions such as raw grafting, crosslinking, make lignin play the role of reinforced rubber;Made jointly using modified carbon black with reed fiber
With greatly reducing the polarity of reed fiber, keep its dissipating effect in rubber more preferable, smaller agglomeration.
