Abstract

A liquid tire sealing composition containing an organic volatile amine or amine salt soluble therein, which is effective to impart corrosion resistance to the metallic belts of a belted tire. The organic volatile amine or amine salt component is selected from the group consisting of lower alkylamines, lower cycloalkylamines, naphthylamines, morpholines, benzothiazoles and benzoate, carbonate and nitrite salts thereof. The composition is introduced into the metallic-belted tire cavity, and the volatile amine penetrates through the rubber and lays down a protective coating on the metallic belt without harming the metal to rubber bonding.

Claims

1. A method of imparting corrosion resistance to the metallic tire reinforcement elements within the elastomeric carcass of a tire which comprises introducing within said tire an aqueous tire sealing composition containing an organic volatile amine or amine salt capable of volatilizing within said tire, migrating to said elastomer, permeating said elastomer and reaching the metallic tire reinforcement elements;

said sealing composition further containing a wheel corrosion inhibitor of a mixture of sodium nitrite and sodium tetraborate pentahydrate in ratios of weight of from 1;

1 to 10;

1.

2. The method of claim 1, further characterized in that the ratio of sodium nitrite to sodium tetraborate pentahydrate is 8:

1 by weight.

3. The method of claim 1, further characterized in that said organic volatile amine or amine salt being selected from the group consisting of isopropylamine, dibutylamine, diisopropylamine, cyclohexylamine, dicyclohexylamine, isopropylhexylamine, ethylmorpholine, naphthylamine, the benzoate, carbonate or nitrite salts thereof and mixtures thereof.

4. The method of claim 3 further characterized in that said amine salt is cyclohexylamine nitrite.
