manufacture example

[0047] [Manufacturing example: Manufacture of rubber composition]

[0048] Using the compositions shown in Table 1 below, rubber compositions for tire treads according to the following Examples and Comparative Examples were produced. The manufacturing method of the rubber composition for tire tread adopts the manufacturing method of tire tread rubber commonly used at present. In Table 1 below, Comparative Example 1 is the type of carbon black, and Comparative Example 2 is the case where the use ratio of the polymer (raw rubber) was changed but no reinforcing resin was used.

Abstract

The invention provides a tread rubber composition for the regeneration of large transport vehicle tires, and the rubber composition comprises: 100 parts by weight of rubber raw materials which contain 57-63 parts by weight of natural rubber and 37-43 parts by weight of butadiene rubber; 53-57 parts by weight of carbon black which has a specific surface area for nitrogen adsorption of 118-122 m2/g, a DBP oil absorption value of 124-128 cc/100g, and a hue value of 119-122; and 3-5 parts by weight of reinforced resin which contains terpene and C9 petroleum resin. The tread rubber composition forthe regeneration of large transport vehicle tires meets requirements of both wearability and durability, and has favourable damage resistance and excellent heating resistance.

Description

technical field [0001] The present invention relates to a tread rubber composition for recycling large truck tires and tires regenerated using the composition, and more particularly, relates to the regeneration of large truck tires excellent in abrasion resistance, breakage resistance and heat resistance A tread rubber composition for use and a tire regenerated using the composition. Background technique [0002] In recent years, with the improvement of economical requirements for automobile tires, especially for large tires used by trucks or large passenger vehicles, new treads are used on tires with worn treads, that is, so-called recycled tires. The performance requirements of tires are getting higher and higher. Such tread rubber compositions for recycled tires are required to be excellent in both wear resistance and heat resistance, but it is difficult to satisfy both of these requirements. [0003] In the case of recycled tires, since the tread thickness tends to be ...
