Abstract
The present invention relates to an air leakage protection polyurethane tyre. The tread (1) is made of a polyurethane raw material with high density, low modulus and high attrition resistance, the carcass (2) is made of a polyurethane raw material with low density, high modulus, high elasticity, low heat generated internally and high fire-resisting property, the tread (1) and the carcass (2) are poured through two times and both adopt a centrifugation molding process, the tread (1) and the carcass (2) are glued closely to form a whle with large thickness and high intensity, without any cord yarn and black carbon being used as reinforced materials. The tyre in accordance with the present invention is high abrasion resistant, does not fear bundling, is not easy to explore, can be used for a long time, and can be used for a running at middle and low speed even when a gas leakage happens. The tyre is not safe and durable but also of environmental protection, can be broad used for various mechanically-propelled vehicles such as large and small autocars, autobikes and the like.
Description
Technical field:
The present invention relates to a kind of air-inflation tyre, especially relate to a kind of pu tire of Runflat.
Background technology:
At present, known air-inflation tyre is that main material is made with the natural rubber still, advantages such as carcass thickness is little though it has, good springiness, traveling comfort are good, easy installation, but also exist to be afraid of thorn, can to blow out, easy to wear, deficiency such as service life is short, often have vehicle when running at high speed because of tyre explosion, the accident that causes car crash that becomes flat takes place; And pollute the environment after the abrasion of reinforcing materials such as the carbon black in the tire, and harmful, and its manufacturing process complexity, production process have three waste discharge, unfavorable environmental protection.Therefore say that present traditional rubber tire hazard factor to the mankind's life and health security presence.
Summary of the invention:
The technical matters that solves:
The fearness thorn that exists for the aerated rubber tyre that overcomes now, can blow out, easy to wear, complex manufacturing, influence unsafe again these deficiencies of human health, not environmental protection, the invention provides a kind of safe green environmental protection tire---air leakage protection polyurethane tyre that new material and novel manufacturing process are made of using.
Technical scheme:
The technical solution adopted for the present invention to solve the technical problems is: tread of tyre be by low modulus, high density, high abrasion, good toughness again the urethane raw cast of environmental protection form, make reinforcing material without carbon black, carcass in the tyre surface is to pour into micro-pore elastomer by modulus of elasticity height, low, the interior liter heat of density urethane raw low, that resistance to heat is good, tyre surface becomes an integral body with the carcass close adhesion, the thickness of its integral thickness ratio same model rubber tire now is twice above, makes reinforcing material without cord fabric thread in the carcass; Each embeddingly has a tyre bead of one or more on the both sides (tire shoulder place) of tire inboard, and the inner edge of carcass has one deck air-retaining liner; Described tire adopts twice cast and centrifugal molding process to make, and can make vacuum tyre and use, and also can make the supporting tire of the inner tube of a tyre and use.
Beneficial effect:
The employed polyurethane synthetic rubber of tire of the present invention has high antiwear characteristics, tear resistance and anti-otch rising characteristic, long service life; Its modular ratio General Purpose Rubber is high more than 2 times, the anti-collapse coefficient is low, load-carrying capacity is high, its tire integral thickness is twice above than General Purpose Rubber tire, thereby have the intensity height, be not afraid of thorn, be difficult for blowing out, even tire becomes flat, can not make to lose control of one's vehicle yet, still can in low speed driving use, as safe as a house.Tire construction of the present invention is simple, do not need any cord fabric thread and carbon black to make reinforcing material in the carcass, production technology is simple, three-waste free discharge in the production process, can not produce after the tire running abrasion yet and pollute environment, more can harm humans health, not only safety durable but also environmental protection can be widely used in power actuated vehicles such as all size automobile, motor bike and use.
Description of drawings:
The invention will be further described below in conjunction with drawings and Examples.
Accompanying drawing is the cross-sectional structure scheme drawing of air leakage protection polyurethane tyre of the present invention.
Among the figure 1, the high abrasion polyurethane tread, 2, microporous polyurethane elasticity carcass, 3, air-retaining liner, 4, tyre bead.
The specific embodiment:
As shown in FIG., air leakage protection polyurethane tyre of the present invention, its tyre surface (1) is made by high density, low modulus, high abrasion, the urethane raw that do not add foaming agent, carcass (2) is by lower density, high-modulus, high resiliency, interiorly rises that heat is low, resistance to heat good, have the urethane raw of an amount of foaming agent to make micro-pore elastomer, the integral thickness of tyre surface and carcass is big, intensity is high, thereby does not need to make reinforcing material with cord fabric thread, carbon black in carcass.Tyre surface and carcass are poured into a mould at twice by the injection machine of the urethane raw of two dress different formulations, adopt centrifugal molding process to make.Before the cast; earlier inflation of tire phantom type and the tyre bead that designs is arranged in the tire-mold, behind the matched moulds, starts centrifugal shaper; inject the tyre surface raw material earlier; reinject in 20～60 second time behind the carcass raw material, shut down, treat tire slaking moulding in 10～30 minutes after; open mould; take out tire, the inflation phantom type in the tire taken out, again through some handle the back the tire finished product.
Claims (1)
- A kind of air-inflation tyre, specifically a kind of air leakage protection polyurethane tyre, comprise high abrasion tyre surface (1), microcellular elastomeric carcass (2), air-retaining liner (3), tyre bead (4), it is characterized in that: the elastomeric microvoid polyurethane carcass of one deck lower density is arranged in the polyurethane tread of one deck high density high abrasion, the carcass inner edge has one deck air-retaining liner, tyre surface becomes an integral body with the carcass close adhesion, the thickness of its integral thickness ratio same model rubber tire now is twice above, make reinforcing material without cord fabric thread and carbon black in the carcass of tire, respectively be embedded with one or more tyre bead on the both sides (tire shoulder place) of tire inboard.
