Abstract

The invention discloses a novel magnetic fluid seal material applied to a radial tire, and belongs to the technical field of tires. The formula of the novel magnetic fluid seal material is characterized by being prepared from methyl-ethyloxy silicone oil, hydrogen-based bentonite, nanoscale neodymium iron boron magnetic iron powder, nanoscale aluminum nickel cobalt magnetic iron powder, octadecanamino-propylamine, polyalkenyl succinimide, methyl palmitate, chloroprene rubber particles and natural rubber latex. The novel magnetic fluid seal material is mainly applied to the inside of the radial tire at a steel cord layer, and is the novel magnetic fluid seal material of the radial tire, which has no influence on dynamic balance of wheels, can quickly and automatically complete gaps (the diameter is smaller than or equal to 10mm), is free from dry rot and freezing, and is high in reliability, good in stability and durable. After the novel magnetic fluid seal material is used, a circle of magnetic fluid is uniformly hung on the inner wall of the tire along with the rotation of the wheels. According to the novel magnetic fluid seal material disclosed by the invention, the magnetic fluid is subjected to an attraction action of the steel cord layer in the tire, so that the magnetic fluid can be stably and uniformly hung on the inner wall of the tire for a long term, and thus the influence on the dynamic balance of the wheels is avoided; compared with the prior art, the novel magnetic fluid seal material disclosed by the invention really has revolutionary improvement.

Description

A kind of magnetic current sealing novel material being applied to radial
Technical field
The invention belongs to tyre technology, the present invention relates to a kind of being applied in radial take MethylethoxylsiliconFluid Fluid as the magnetic fluid tire seal novel material of external phase.
Background technology
Automobile and various motor vehicle one of important symbol becoming modern civilization, in its use procedure, tire is punctured by the nail on road surface or tip and hard object matter and causes disappointing, and the phenomenon causing vehicle normally not exercise often occurs.The automatic mending tyre liquid occurred the earliest is in U.S. army's wheeled vehicle in twenty or thirty age in last century, start application, in the tire of military vehicle, poured into automatic mending tyre liquid, apart from modern existing 80-90 history.Its advantage of the automatic mending tyre liquid of prior art is: tire patching need not take off tire, within 3 seconds, can mend; But, also there is more shortcoming: the transient equilibrium 1, affecting wheel: after employing a tank automatic mending tyre liquid, the inner bottom part place of tire remains the liquid of 200ml-300ml, as same eccentric wheel when this liquid makes wheel operate, both noise was added, again reduce stability, the traffic safety hidden danger that therefore have impact on transient equilibrium when wheel operates and bring to a certain extent.2, when the wound diameter of tire is greater than 6mm, automatic mending tyre liquid is inoperative.3, also have the automatic mending tyre liquid product of some inflation pot types, its composition can only make the tire lost heart temporarily inflate and subtract leakage, till treating that nearest service station exercised by vehicle.4, the tire repair liquid product had can dry up or meet cold snap and freeze in tire, not only loses mending-leakage effect, can damage the inwall of tire on the contrary.
The content of invention
The object of the invention is: provide one to be applied in radial, do not affect the transient equilibrium of wheel, energy fast self-compensating breach (diameter is less than or equal to 10mm), do not dry up, do not freeze, reliability is high, good stability, magnetic fluid tire seal novel material durable for a long time.
For achieving the above object, the magnetic fluid tire seal novel material of the technical solution adopted in the present invention to be a kind of MethylethoxylsiliconFluid Fluid be external phase, the feature of its formula is: by MethylethoxylsiliconFluid Fluid, hydrogen base bentonite, nano level neodymium-iron-boron iron powder, nano level alnico magnet powder, 18 amino propylamine, the many succimides of polyisobutene, Uniphat A60, chloroprene rubber particle, nature rubber latex composition.
The weight percent of its component is:
MethylethoxylsiliconFluid Fluid 65%--84%
Hydrogen base bentonite 1%--3%
Nano level neodymium-iron-boron iron powder 1%--2%
Nano level alnico magnet powder 2%--6%
18 amino propylamine 1%--2%
Polyisobutene many succimides 1%--2%
Uniphat A60 2%--5%
Chloroprene rubber particle (60 order-350 order) 5%--8%
Nature rubber latex 3%--7%
A kind of magnetic current sealing novel material being applied to radial of the present invention compared with the existing technology has the following advantages and positive effect: along with meridian metal-cord tire the popularizing in the whole world of advanced technology, on current market, automatic mending tyre liquid product miscellaneous is because of all reasons, is difficult to " lifelong together with tire ".Unlike the prior art: 1, invention applies Magneticfluid Seal Technique, nano level neodymium-iron-boron iron powder and nano level alnico magnet powder are highly dispersed in MethylethoxylsiliconFluid Fluid, make on product tape of the present invention magnetic, after employing product of the present invention, along with the rotation of wheel, tire inner wall hangs up a circle equably and has had certain thickness magnetic current sealing novel material, magnetic current sealing novel material of the present invention is by the suction of metal-cord in tire, can be steady in a long-term and hang over equably on tire inner wall, thus do not affect the transient equilibrium of wheel, this is compared with prior art revolutionary improvement really.2, be that the chloroprene rubber grain that 60 order-350 order adsorptive poweies are strong makes weighting agent by granularity in the middle of the present invention, at surface adsorption a large amount of nano level neodymium-iron-boron iron powders and the nano level alnico magnet powder of chloroprene rubber grain, they are scattered in MethylethoxylsiliconFluid Fluid with the form of sponge mesh network structure, during use, tire is worn as pricked by the iron nail being less than or equal to 10mm bore, before not pulling out iron nail, magnetic current sealing novel material near iron nail is assembled to the nail tip place pierced in tire, until wrapped up and sealed, afterwards, also gas leakage is there will not be in the moment of pulling out iron nail, the effect of zero leakage can be played, this also leads over prior art.3, to take MethylethoxylsiliconFluid Fluid as its advantage of external phase be in the present invention: the reliability of MethylethoxylsiliconFluid Fluid is high, good stability, it does not dry up, can be antirust, the effect having moist rubber tyre and prevent rubber tyre from chapping, can under the environment of-60 DEG C ~ 180 DEG C life-time service.In addition, present invention employs 18 amino propylamine and the many succimides of polyisobutene are hyper-dispersant, Uniphat A60 is rust-preventive agent, and nature rubber latex is tackiness agent.A kind of magnetic current sealing novel material being applied to radial of the present invention is better than prior art, and product of the present invention is the innovative product that " can accompany lifelong " with tire.
Product of the present invention to apply in such a way: 1, be stored in compression gas tank by the novel material of the present invention of magnetic fluid state, added in tire use by user.2, the novel material of the present invention of magnetic fluid state is stored in commercial bottle and a tyre little air pump, is used voluntarily by user.
