Description
Technical field
The present invention relates to tire product technical field, specially a kind of casting type polyester polyethers bi-material layers dual density exempts to inflate
Tire.
Background technique
Tire is the annular elastic rubber product that the ground connection in various vehicles or mechanically assembled rolls, and is typically mounted on
In alloy rim, vehicle body can be supported, buffers foreign impacts, realize the contact with road surface and guarantees the driving performance of vehicle, tire
Often being used under complicated and exacting terms, it subjects various modifications, load, power and high/low temperature effect in motion, because
This must load-carrying properties with higher, hauling ability, cushion performance, meanwhile, also require have high-wearing feature and flexible resistance,
And low rolling resistance and heat generation, the half that the world consumes rubber mass are used for tire production, it is seen that tire consumes rubber
Ability.
Existing polyurethane (PU) foamed hollow non-inflatable tyre, have it is thoroughly anti-pierce through, exempt from inflation, is high-intensitive, lightweight it is resistance to
With, elasticity is moderate, from repairing the advantages that, PU foamed hollow non-inflatable tyre is a kind of tire that need not be inflated, and is closed using micro-
Macromolecule polymeric material is formed not connected and fine and close micro air chamber by hole foaming technique, and inside is full of high elasticity sponge body
On the one hand the tire of shape, this high molecular material foam sponge body utilize tridimensional network and permanent restorability, be squeezed,
Original shape can still be restored after stretching, tire is allowed to keep shape invariance, it is on the other hand again mutual using countless interconnections
Mutually independent micro- closed pore makes tire possess excellent elasticity and cushion effect, and can sufficiently bear the pressure change of tire, allows wheel
Whenever tire all keeps enough strong, therefore, PU foamed hollow non-inflatable tyre because of its unique advantage, gradually at
For the main force of tire market, market prospects are considerable.
But although existing PU foamed hollow non-inflatable tyre have the advantages that it is multiple, lacked there is also following
Fall into: existing hollow non-inflatable tyre is generally mono-material product, is monomer structure, and shock-absorbing effect is poor, not wear-resisting, brake and ground
Dry friction and wear is obvious, and it is poor with ground grip to brake, and is exactly on the other hand mono-material monomer structure, color is single, and appearance is not
Enough novel and beautifuls, and night there is not fluorescent effect, it is not safe enough.
Summary of the invention
The purpose of the present invention is to provide a kind of casting type polyester polyethers bi-material layers dual density non-inflatable tyres, on solving
The existing hollow non-inflatable tyre for stating background technique proposition is generally mono-material product, is monomer structure, shock-absorbing effect is poor, no

The production technology of this patent non-inflatable tyre is as described below:
S1, nylon coil 13(or wire coil are reinforced in placement in steel mold first), then utilize two component low-pressure blowing machines
(or high pressure be soaked machine) feeds intake, and the first step uses macromolecule polyester foamed material, cast tire crown layer 2, by prefabricated macromolecule
Polyester foamed elastomer material component A (containing crosslinking agent, catalyst, foaming agent, foam stabilizer, color agent etc.), B component raw material are added
The molten device of machine corresponding A and the molten device of B, machine set A, B component ratio are fed to discharge port simultaneously from A charging pump and B charging pump,
In casting exit, a high speed agitator is installed, the A material for simultaneously flowing through this outlet and B material are mixed rapidly and is quickly stirred
Uniformly, near Quick pouring to high-speed rotating steel mold feeding inlet, mold generates centrifugal force and throws raw material into mold inner-cavity, A,
B mixture quickly crosslinks reaction within the set time, generates non-foamed elastomer, forms the polyester elastomer of crown layer 2,
Area of section occupies about the 1/3 of mold inner-cavity global sections area, and the color of this crown layer 2 can be adjusted to any one before manufacture
Color；
S2, second step, using high molecular polyether foamed material, 1 layer 1 of cast tire ontology, the polyester foamed elastomer of crown layer 2
After cross-linking curing in 2 to 3 minutes, second of raw material high molecular polyether micro cellular foam is poured by second group of foaming machines
The inner cavity in same mold remainder gap, using two groups of low-pressure blowing machines, by prefabricated high molecular polyether PU micro cellular foam raw material A group
Part (crosslinking agent, catalyst, foaming agent, foam stabilizer, pigment, reflective or fluorescent material etc. is added), B component add the molten device of corresponding A
And the molten device of B, machine are fed to discharge port, in life simultaneously by scientific matching A/B component ratio from A charging pump and B charging pump
It produces at equipment priming outlet, a high speed agitator is installed, the A material for flowing through this outlet and B material are uniformly mixed rapidly, are injected into
The inner cavity of tire steel mold remainder volume, A, B mixture crosslink reaction within the set time, generate consistent seal micropore gas
The foaming body of room, the full foaming in inner cavity in tire steel mold remainder gap, curing form (about 60 seconds), at this time tire body 1
It is integral with the bonding shape of crown layer 2, it opens mold and takes out tire, manufacture completion.
Tire body 1 and crown layer 2 is made using two different serial tissue structure materials in the device in this way, and the two is logical
It crosses and forms the compound structure of an entirety, can be better, effective solution tire tear resistance is common, and shock-absorbing effect is poor
The problems such as poor, not wear-resisting with braking effect, makes the device more practical reliable and secure, and 1 two sidewalls of tire body are inlaid with nothing
The consistent heavy hole of several shapes or variform heavy hole, multiple heavy holes are distributed in 1 two sides of tire body, due to heavy hole connection or
Mutually not through the heavy hole of 1 two sidewalls of tire body can be symmetrically arranged or asymmetric distribution, and purpose reaches not only beautiful, but also saves material
Material, reduces cost, and crown layer 2 is made of polyester foamed elastomer, tire body 1 is also by high molecular polyether microporous foam three
Structural support is tieed up, makes 2 hardness of crown layer high by both different performance materials, although 1 hardness of tire body is relatively low,
Two kinds of materials, two kinds of structures are combined with each other, and can effectively be carried compression shock and be stretched, heat effect be substantially reduced, to reach more
It is wear-resisting.
