Description
Technical field
The present invention relates to a kind of rubber composition, particularly relate to a kind of rubber composition and use the inflated wheel of this rubber composition
Tire.
Background technology
Rubber is a kind of chain macromolecular material, adds vulcanizing agent and can produce cross-linking reaction therewith, forms space network, make
Rubber is become elastomeric material from plastic material, and elasticity is high, plasticity is little, intensity is big to make rubber have within the scope of compared with wide temperature
Serviceability, but the hardness of vulcanizate is low.It is known that tire and rubber are required for the vulcanizate of higher hardness, it is used for changing
Kind and raising vulcanizate hardness and modulus method has a lot, such as increases vulcanizing agent consumption or the consumption of activating agent, adds phenol
The methods such as urea formaldehyde.Use the means increasing vulcanizing agent consumption, it is easy to cause the vulcanizing agent consumptions such as sulphur too high, the sizing material initial stage
Curingprocess rate is too fast, and during extrusion, sizing material is susceptible to rubber incipient scorch, and sizing material structural behaviour is unstable simultaneously.Tyre triangular glue at present
The high carbon black of the many uses of sizing material, high sulfur content make its hardness reach about 90 degree requirements, and high sulfur consumption makes rubber revert now
As seriously, observing its recovery by sulphur varied curve and reach about 20%.So can cause under sizing material in use performance
Fall, shortens the serviceability of tire.
Add phenolic reinforced resin with methylene donor with the use of forming resin crosslinks network in rubbery parent substance,
In process, resin has plasticising and peptizaiton to uncured rubber, can be effectively increased hardness and the modulus of rubber after sulfuration.
Conventional phenolic resinoid includes phenol-formaldehyde resin, tall oil modified phenol-formaldehyde resin, cashew nut oil modified P-F tree
Fat, rosin modified phenol-formaldehyde resin, melamine phenol-formaldehyde resin modified, isophthalic two or two resinox etc. can be with methylene
The resin that base donor reacts further.
Conventional methylene donor as phenolic resinoid crosslinking has hexa (being abbreviated as HMT), hexa methoxy first
Base melamine (is abbreviated as HMMM or H3M).HMT molecular weight is little, discharges the same of methylene in course of reaction
Time have amine substance to discharge, amine substance can promote the reaction between methylene donor and methylene receptor, thus and phenol
The reaction speed of aldehydes reinforced resin is fast, it is possible to improve rapidly modulus and the hardness of rubber composite.But, due to this quickly
Reaction makes HMT and the cross-linked network structure structure of phenolic resin formation imperfection so that the fragility of elastomeric material increases,
It is being heated and the physical property decline of rubber under External Force Acting.In rubber industry, term is the recovery of rubber, improves this
It act as improving anti-recovery effect.Using the triangle rubber of HMT, its recovery is very fast.It is used alone HMT as industry
During methyl donor, sizing material elongation at break is low, breaking strength is low, anti-recovery rate is low.
With melamine as core in the molecular structure of HMMM, the industry methyl being connected in atom N can be after sloughing methyl alcohol
Progressively react with methylene receptor.In the process, reaction is more gentle, so that in a long time could be complete
Full response, reaches to improve compound modulus and the effect of hardness.When being used alone HMMM as methylene donor, it will be apparent that
Result is exactly that sizing material 100% stress at definite elongation is low.Owing to this reaction is more gentle, the cross-linked network formed is fairly perfect, network
Structure be heated and External Force Acting under relatively stable.Thus, the physical property of rubber be heated and External Force Acting under more stable,
Anti-reversion behaviour is preferable.But, owing to the sulfuration of rubber needs to be completed in a relatively short time, thus HMMM is less
For being used in conjunction with phenol novolacs class, its feature is not the most played.
Chinese invention patent CN201210131533.4 provides triangular rubber core composition under a kind of aging-resistant all-steel radial tire,
Wherein contain the components such as reinforcing phenolic resin, melamine type methylene donor and modified resorcinol, all-steel radial tire can be improved
The ageing-resistant ability of lower triangular rubber core, improves the service life of tire.But sizing material adds resorcinol and/or resorcinol phenol
Urea formaldehyde is easily fuming in sizing material process, causes the pollution to environment, and to human carcinogen.Even if using between modification
Based resins, also cannot avoid the pollution problem of environment completely.For the cost of raw material, the price of resorcinol is benzene
The several times of phenol, make significantly improve in this way the cost of raw material of tire.
Additionally, when multiple methylene donor and multiple methylene receptor are reacted jointly, the problem that competing poly-reaction occurs unavoidably.
Owing to the reactivity of resorcinol Yu methylene donor is tens times of phenol, thus it can preferentially react, and easily produces
The problem that green coke burns, the most highly active HMT easily occurs Jiao with resorcinol or resorcinol resinoid when reacting
The phenomenon burnt.

Stress at definite elongation changes less relative to embodiment 3.
The strengthening action of phenolic resin is divided into resin dispersion in rubber and is cross-linked to form two, resin network with methylene donor
Process, the most unmodified phenolic resin of phenol-formaldehyde resin modified reduces the polarity of phenolic resin, can improve phenolic resin and rubber
Compatibility, improve resin degree of scatter in sizing material, therefore show more preferable reinforcing effect, cashew nut oil modified alkyd resin
Owing to alkyl chain long in cashew nut oil contributes to the compatibility of resin and rubber, so reinforcing effect highlights, cashew nut oil itself simultaneously
Can use as phenol, reactivity point is many relative to tall oil modified alkyd resin, and rosin modified phenolic resin is due to its rosin acid
Sterically hindered bigger phenolic hydroxyl group generation esterification easily and on phenolic resin, little on the impact of its avtive spot, and tall oil
Phenol-formaldehyde resin modified can react with the avtive spot on phenolic resin due to the ready denier oil acid contained, and causes its active sites to be counted
Fewer than rosin modified phenolic resin, ultimately result in both reinforcing effect difference.Melamine phenol-formaldehyde resin modified is due to its pole
Property to compare other several phenol-formaldehyde resin modifieds high, with the poor compatibility of rubber, its dispersion in sizing material relatively other modified phenolic resin
Fat is poor, ultimately results in its reinforcing effect poor.
