Description
Technical field
The utility model belongs to rubber tyre product technique field, specifically, being related to a kind of high resiliency hollow molding rubber
Rubber tire tire.
Background technique
Tire is one of automobile important composition component, and main function is support car mass, bears car load, transmitting
Traction and braking torque guarantee wheel and road adherence；Vibration and impact force when mitigation and absorption running car, prevent vapour
Vehicle components are adapted to automobile high-speed performance and reduce noise when driving, guarantee running car by high vibration and earlier period damage
Safety, control stability, comfort and energy saving economy.
Rubber tyre should guarantee its intensity and wearability, guarantee that its is flexible again according to requiring, and refer to guarantee two
Mark, is usually designed into Tire & Tube structure, cover tire proof strength and wearability, guarantees its elasticity after tire tube air-inflating, makes its knot
Structure is complicated, and the inner tube of a tyre is also easy gas leakage, increases maintenance cost, is also easy to produce safety accident.
Because that can not inflate aeroelastic requirements are not achieved, intensity and elasticity are current tubeless rubbers in existing tubeless structure tire
The maximum contradiction of rubber tire tire is less rubber material dosage, cost is reduced, by tire design at hollow reinforcing rib structure, because of it
The limitation of structure, after the completion of injection, intracavitary mold core does not realize automatic demoulding, can only be using mold core is moved back by hand, and production efficiency is low, work
People's large labor intensity, thus existing tubeless structure tire be only used for it is small-sized, it is desirable that not high occasion, such as trolley, transhipment
Wheel tire cannot be widely applied.
The prior art is in the non-inflatable tyre product based on shared bicycle, and generally at least there are two types of bodies for the materials of tire
System, one is using SBS (styrene series thermoplastic elastomer) and SEBS (using polystyrene as end segment, with polybutadiene plus hydrogen
Obtained ethylene-butene copolymer be intermediate elastic block linear tri-block copolymer) raw material plastics it is physico " knot
It is brilliant " system (rub and visit bicycle, tire as shown in Figure 1, hole is vertical hole)；One is contour with PU (polyurethane), RB (rubber)
Molecular material is that (hello bicycle, tire cross-section as shown in Figure 2, hole are horizontal for chemical reaction method " crosslinking " system of raw material
Looping pit), two kinds of systems can be injection moulded with melt injection technique.
Although two kinds of systems are all widely applied, all have the shortcomings that corresponding:
SBS the and SEBS material price of the first system is high, and chance high temperature easily softens and wearability is poor；
In second of system, the molding of tire is first to be injected into strip semi-finished product in a mold, and hole can only be straight hole,
Then it after being truncated further according to corresponding specification, is transferred in sulfurizing mould and is vulcanized, molding and vulcanization will be separated and be carried out, although material
Advantage of lower cost, but high process cost are expected, moreover, since there is hole in inside, sulfidation is difficult to ensure in sulfidation
Uniformly, finished product dynamic balancing effect is poor for entire semi-finished product vulcanization, and after vulcanization, intrapore high pressure gas is also easy to fast in die sinking
Speed is expanded and is exploded, and is caused hole thin-walled to rupture and is become waste product, in technical process, rejection rate is higher；It should also be noted that,
Vulcanization is carried out in dedicated vulcanization machine, need to be pressurizeed again, be heated to rubber product, consumes energy, is time-consuming, at high cost, being rubber product
The big disadvantage of the one of technique.
There is also same defects for both the above system: hole is distributed in the different places in portion in or beyond tire, such
Structure causes tire pressure-bearing size uneven, so that tire has different stress points, thus cause the dynamic balancing of tire uneven,
User can experience and jolt, and comfort level is bad.And hole can be generated with the extension for using the time, and under the effect of the pressure
The phenomenon that collapsing, so as to shorten the service life of tire.
Through retrieving, Chinese patent publication No. CN105599214A, publication date 2016.05.25, denomination of invention: one kind is exempted to fill
The integrally formed pressure injection method of air filled tyre, comprising the following steps: 1) configured non-inflatable tyre manufacture raw material is put into material stock
Case, and stir evenly；2) pre- Hot-pressed injector is to 180 DEG C -190 DEG C；3) press injector pressure is promoted to 50Pa-60Pa；4) adjust into
Material speed is 10m/s-20m/s；5) dwell time is adjusted to 2min-3min；6) non-inflatable tyre in step 1) is manufactured former
Material is injected into press injector, according to preset mode initiating task；7) it successively after molding, injection, hot melt, cooling, die sinking, obtains
Non-inflatable tyre.The simple process is operated conveniently without repeatedly processing, at low cost；Non-inflatable tyre structure obtained is uniform
Rationally, without point of Tire & Tube, the frictional force and resistance between Tire & Tube are eliminated.But the material TPE's of invention application is resistance to
Hot to be not so good as rubber, as the temperature rises and physical property declines by a big margin, thus the scope of application is restricted.Meanwhile it compressing and becoming
It is poor that shape, elastic recovery, durability are equal to rubber phase, and similar rubber is also often higher than in price.
Through retrieving, Chinese patent publication No. CN 107618143 A, publication date 2018.01.23, a kind of denomination of invention: rubber
