Although the rubber wear-resisting property in the patent is preferable, ageing-resistant performance is poor, thus the automobile produced is matched
Part is shorter using the longevity.
Invention content
The object of the present invention is to provide a kind of for making rubber of shock-absorbing sleeve and preparation method thereof, it is advantageous that, rubber
The ageing-resistant performance of glue is good, good reliability.
The present invention above-mentioned technical purpose technical scheme is that：
A kind of rubber for being used to make shock-absorbing sleeve, according to the mass fraction, including：80-120 parts of 5# natural gums, 40-55 parts
SBR1502,70-100 parts of carbon black, 15-25 parts of clay, 20-35 parts of paraffin oil, 2-4 parts of stearic acid, 6-14 parts of zinc oxide are prevented old
6-10 parts of agent, 8-15 parts of softening agent, 2-6 parts of accelerating agent, 4-7 parts of sulphur, 8-12 parts of reinforcing agent, 3-5 parts of chrome oxide green.
Preferably, according to the mass fraction, including：95-103 parts of 5# natural gums, 46-50 parts of SBR1502, carbon black 84-90
Part, 19-21 parts of clay, 28-30 parts of paraffin oil, 3-4 parts of stearic acid, 9-11 parts of zinc oxide, 7-8 parts of anti-aging agent, softening agent 11-12
Part, 3-4 parts of accelerating agent, 5-6 parts of sulphur, 9-10 parts of reinforcing agent, 4-5 parts of chrome oxide green.
By using above-mentioned technical proposal, carbon black has the function of reinforcement in rubber, and the stretching that can enhance rubber is strong
Degree, tearing strength and wear-resisting property, thus the ageing-resistant performance of rubber is enhanced to a certain extent.Paraffin oil can middle aromatic hydrocarbons
Content is low, thus can reduce the consumption of vulcanizing agent needed for sulfidation, so as to reduce cost.In addition, paraffin oil has
Low volatility relative to other rubber filling oils, improves the oxidative degradation performance of rubber, and low volatility helps to prevent
Aging is shunk, and is conducive to improve the bad appearance of rubber, so as to extend the service life of shock-absorbing sleeve.Stearic acid, oxidation
Zinc forms activation sulfur system, improves solubility of the zinc oxide in rubber, meanwhile, stearic acid and zinc oxide generate solvable
Property zinc salt, zinc salt and cross-bond chelate, vulcanization are made to generate a large amount of short cross-bonds, improves crosslink density, when temperature is higher,
It since cross-bond is large number of, is not easy to be broken simultaneously, thus improves the high temperature resistance of rubber；Add in accelerating agent and sulphur
After sulphur, vulcanized, sheared by external force, high temperature promotes the chain molecule in rubber to be cross-linked into network molecule, strengthen its stretching
Intensity, hardness, elasticity；After adding in chrome oxide green, rubber is coloured, while improve the heat resistance of rubber, so as to slow
Rubber high temperature ageing is solved.
Preferably, the carbon black is the mixture of N330 and N550, the mass ratio of the N330 and N550 are 1: 2.
By using above-mentioned technical proposal, the grain size of N330 is smaller, can improve the tensile strength and wear-resisting property of rubber,
And the grain size of N550 is larger, can improve the hardness and heat conductivility of rubber, while by the mixing of N330 and N550, N330 can
N550 plain cloths in rubber is promoted to be distributed, so as to make the hardness of rubber each section uniform, stable structure, and the amount of N550 is extra
The amount of N330 then makes the average grain diameter of carbon black close to the grain size of N550, so as to preferably promote the hardness and thermal conductivity of rubber.
Preferably, the anti-aging agent is antioxidant 4010NA, the mixture of anti-aging agent RD, antioxidant 4020, it is described anti-
Old agent 4010NA, anti-aging agent RD, antioxidant 4020 mass ratio be 4: 3: 3.
By using above-mentioned technical proposal, antioxidant 4010NA, there is good antioxygen, ozone-resistant, freedom from cracking and inhibition
The effect of the harmful metal ions such as copper manganese, while improve the dispersibility of anti-aging agent；Anti-aging agent RD improves the heat resistance of rubber
Energy and inoxidizability improve the intermiscibility of anti-aging agent and rubber；Antioxidant 4020 has good inoxidizability and anti-flexion
Fatigue aging, while reduce irritation of the anti-aging agent to human skin.It is thus mixed by three kinds of anti-aging agents anti-
Old agent has more excellent characteristic.
Preferably, mixture of the softening agent for coumarone indene resin and paraffin, the coumarone indene resin and paraffin
Mass ratio is 3: 1.
By using above-mentioned technical proposal, by the combination of coumarone indene resin and rubber, make rubber that there is good bonding
Property, while pressure-sensitive and hot melt are improved, the compatibility of rubber and sulphur is improved after thawing, contributes to sulphur and carbon black
Dispersion, prevent from burning；Paraffin can improve the processing performance of rubber, increase the plasticity of rubber, when reducing compound viscosity and being kneaded
Temperature, change dispersibility and mixed type, meanwhile, paraffin is not engaged in reacting during rubber vulcanization, is only free in sulphur
Change in glue, because the concentration of vulcanizate surface wax is very low, paraffin gradually moves to vulcanizate surface, forms paraffin-protected film,
It avoids vulcanizate and oxygen, ozone is in direct contact, so as to protect rubber not by oxygen, ozone aging.Simultaneously as it forms
Paraffin-protected film, prevents rubber to be directly in contact in injection molding machine with mold, thus when rubber sleeve injection molding molds, rubber
It is not easy to stick on mold, improves the ratio of briquetting of rubber sleeve, thus special releasing agent need not be added in after adding in paraffin, be convenient for
The production of shock-absorbing sleeve.
Preferably, the accelerating agent is the mixture of DM, CZ, TMTD, the mass ratio of described DM, CZ, TMTD are 5: 2:
1。
By using above-mentioned technical proposal, DM curing temperatures are high, there is significant aftereffect, it is therefore prevented that the hair of getting up early vulcanization
It is raw, improve the quality of the vulcanization of rubber；CZ equally has significant aftereffect, and after temperature is higher than 138 DEG C, facilitation is shown
Enhancing is write, vulcanization time is reduced, improves curing efficiency；TMTD improves curingprocess rate, while improves the safety of incipient scorch
Property.
Preferably, the reinforcing agent is nanometer silicon carbide.
By using above-mentioned technical proposal, nanometer silicon carbide has extremely strong hardness and wear-resisting property, after adding in rubber, energy
The hardness and wear-resisting property of rubber are obviously improved, reduces the abrasion during shock-absorbing sleeve use, scapegoat has crossed subtracting for shock-absorbing sleeve
Effect is shaken, while nanometer silicon carbide improves the heat resistance and heat conductivility of rubber, on the one hand prevents shock-absorbing sleeve from using process
In constantly Compression and Expansion heating soften, and then damping effect is caused to be deteriorated, on the other hand, accelerate heat dissipation, make the temperature of rubber
It is not easy to increase, so as to indirectly improve the damping effect of shock-absorbing sleeve.
A kind of preparation method for the rubber for being used to make shock-absorbing sleeve, includes the following steps：
S1, it is thin it is logical plasticate, 5# natural gums and SBR1502 are added in by above-mentioned mass fraction in mixer, in 30-50 DEG C of condition
Under, it is thin it is logical plasticate 10-12 times after carry floating weight；
S2, mixing add in carbon black, clay and paraffin oil, in 60-85 DEG C of item into the mixer of S1 by above-mentioned mass fraction
