Embodiment 1

[0034]

[0035] Manufacturing process of the present invention is:

[0036] 1. Ingredients

[0037] The above components are weighed sequentially according to the weight ratio for later use.

[0038] Second, mixing

[0039] 1. The order of adding ingredients for mixing is

[0040] The natural rubber and butadiene rubber are first milled, and then milled in the following order:

[0041] In the second step, add anti-aging agent 4020 and powders such as RD, OK2122, TNB88, 0411 and hydrocarbon resin for mixing.

[0042] The third step is to add carbon black for mixing;

[0043] The fourth step is to add aromatic hydrocarbon oil for mixing;

[0044] The fifth step is to meet the process requirements and deglue. The rubber is cooled for more than 24 hours.

[0045] The sixth step is to add the rubber material into the internal mixer, add N-tert-butyl-2-benzothiazole sulfenamide and insoluble sulfur for mixing, meet the technological conditions for debinding, and cool.

Abstract

The invention relates to a formulated rubber compound for a bead rim cushion of agricultural radial ply tire, and a rolling and refining process thereof. The components of the rubber compound comprise natural rubber, rare earth butadiene rubber, carbon black, zinc oxide, stearic acid, insoluble sulfur, etc. The rubber compound is prepared by special rolling and refining process. The intensity of the rolled and refined rubber compound is improved 20%, the wear resistant performance is improved 30%, and service life of the tire is prolonged.

Description

technical field [0001] The invention relates to an agricultural radial tire spigot protective rubber formula and rolling process thereof, which are mainly used for radial tires of farmland operation vehicles. Background technique [0002] In the world, since the Italian Pirelli Company trial-produced agricultural radial tires in 1955, its superiority in use performance has been widely recognized by users in European and American countries, so the international agricultural radial tires have developed rapidly. In recent years, my country's agricultural machinery has entered a stage of rapid development, but the radialization of agricultural tire series has lagged far behind. The development prospect of agricultural radial tires is bright and will bring huge market effects and social effects. The development and application of complete sets of production technology for agricultural radial tires not only breaks through the technical bottleneck restricting the development of ag...
