    This invention relates to a process for producing a reinforced tire utilizing polyurea or polyuPethane formulations having low hysteresis. The polymer having low hysteresis is formed by reacting a prepolymer of an aromatic isocyanate and a high molecular weight difunctional polyol with a chain extender mix comprising an aromatic diamine and difunctional polyol. In these compositions the aromatic diisocyanate and aromatic diamine are selected so that there is substantial symmetry between the molecules. The reinforcement used is preferably an aromatic polyamide.

    This invention relates to methods for making polyurethane tires operating under severe shock and vibration conditions and can be used in the tire industry.
    The purpose of the invention is to increase the resistance of tires to heat loads, tearing and tearing.
    Example 1. Preparation of a prepolymer with a content of 5.17 wt.% Free NCO-group.
    The method is carried out by reacting with a mixing of 1000 mas. polytetramethylene glycol with a molar mass of 2000 and a hydroxyl number of 5 and 217.7 wt.h. mixtures of toluene-254-diisocyanate and toluene-2,6-diisocyanate
    (with the ratio of isomers 80:20) at 80 ° C for 1 h (the ratio of isomers can be any). Then a mixture of chain extenders is prepared by mixing 1000 mash. polytetramethylene glycol with a mol. mass of 2000 and a hydroxyl number of 56 and 122 wt.h. toluene diamine (a mixture of isomers 2.4-2.6 at a ratio of 80:20). Synthesis is carried out in the presence of 350 mph. Dioctylphthalate h 10 mac. catalyst.
    Tires are made by molding a tire body around the cord, reinforcing the winding around the core, around the circumference of the tire body, forming a tread on the reinforcing cord and fixing it on the body

    As a polyurethane elastomer, use is made of a reaction product of 60 mash, a mixture of chain extenders and 100 mash. a polyalkylene-etherisocyanate prepolymer "After controlling the composition, it is vulcanized at 100 ° C, °
    After production, tires are pumped under a pressure of 21 kg / cm2 for testing,
    Some of them put a load of 246 103 kg and rotate them until reaching a speed of 75 km / h.
    Another part of the tires is subjected to a load of kg and rotated for an hour at a speed of 180 km / h, then at a speed of 190 km / h for 10 minutes and at a speed of 200 km / h until destruction.
    1 All tires withstand the test when rotating at a speed of 190 km / h, and when rotating at a speed of 200 km / h only temporarily
    At the end of the test, the temperature of the tire tread is measured. Usually it is equal to 55-60 ° С „

    Invention Formula
    A method of manufacturing reinforced polyurethane tires by injection molding a composition based on a prepolymer with terminal isocyanate groups and an aromatic diamine into a mold for tires, encapsulating the reinforcing cord in a tire, followed by vulcanization of the composition, characterized in that, in order to increase the resistance of the tires to heat loads , to rupture and strain, as a prepolymer, use the product of the interaction of an excess of 2,4-2,6-toluylene diisocyanate or phenylene diisocyanate with polytetramethylene glycol or with a molicaprolactone with a molar mass of 650–2900 containing 2958–11% of free NCO rpynns, and a compound selected from the group including toluene diamine, diethylene diamine diamine, methaphenylenediamine, p metaphenylene diamine, diamino-4-chloro p-isobutyl-benzoate-tetraisopropylmethylananiline, | 5 ™ hlar-toluene diamine or a mixture of the indicated diamine with polytetramethylene glycol and polycaprolactone with a molar mass of 630-2900 at a mass ratio of 1-4; 1, respectively.

     The TDA and the chain extender mixture react too quickly to form
    The viscosity of the prepolymer is very high; it cannot be mixed with a mixture of chain extenders.
