JPH1120042A - Manufacture of studless tire - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a studless tire instead of a spike tire causing a dust public nuisance. SOLUTION: The studless tire is obtained by mixing fine powder of charcoal and special water repellent rubber within rubber of the tire, and executing a sipe of knurling on a surface of the tire with fine lines.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a studless tire for shaving a pavement road surface so as not to generate dust pollution, in view of the fact that a spiked tire has cut a pavement road surface to cause dust pollution. It is.

[0002]

2. Description of the Related Art Since spike tires cause dust pollution by shaving a pavement road surface, there have been some tires which are softer than a pavement road surface but harder than a frozen road surface to increase friction by scratching the frozen road surface. It incorporates walnut shells and is already in practical use. This is called an A type. Another measure against dust pollution was that slip on frozen roads was caused by the fact that water melted by friction between tires and frozen roads became a thin water film and lost frictional resistance. The film is devised so that the tire itself absorbs and repels the film to eliminate moisture. This has been developed by mixing a special water-repellent rubber into the tire to repel water, or by squeezing a fine line on the surface of the tire to absorb this water and absorbing moisture. . This is called type B.

[0003]

As described in the prior art, there are A type and B type as dust pollution countermeasures, but they are sufficiently effective as a studless tire having both types. There were none. Therefore, an object of the present invention is to sufficiently combine the effects of both the A type and the B type.

[0004]

The means is a method in which pulverized charcoal of charcoal and special water-repellent rubber are mixed into tire rubber, and a sipe in which extremely fine lines are cut into the surface of the tire is provided. Specifically, charcoal pulverized coal has both the effects of both the A type and the B type. Charcoal is wood used, Mohs hardness 1-6 depending on manufacturing method
It is extremely easy to produce charcoal that is softer than a dry road surface and harder than a frozen road surface, which is the condition for the type A described above. The water absorption of charcoal is famous, but the degree of water absorption is unknown. To absorb moisture.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION It is considered that charcoal of a diameter of about 0.3 mm is mixed in a studless tire. If there is a person who has an exclusive right to special water-repellent rubber or a fine line sipe on the tire surface, the transfer of the right to use will be carried out after that.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention will be omitted because it is a method invention.

[0007]

Since the present invention mainly uses charcoal, it is extremely effective as an invention of a studless tire, and it is indispensable to contribute to industrial development.
