Problems solved by technology

However, the current rubber material of the belt layer has poor safety performance during processing, and the bonding performance between the rubber material and the steel cord is not good.
Scorching is prone to occur during the mixing process, affecting product quality, increasing rubber consumption, and poor cord flatness
At the same time, aromatic oil is used in the existing belt rubber formula to improve the processing performance of the rubber compound, but in the actual production process, the aromatic oil will greatly affect the physical properties of the vulcanized rubber and reduce the adhesion between the rubber compound and the steel cord performance

Abstract

The invention belongs to the technical field of tyre rubber, and concretely relates to a radial-tire belt compound applied to a cross-country fork truck with load of 5.8 t and a preparation method thereof. The radial-tire belt compound applied to a cross-country fork truck with load of 5.8 t is composed of the following raw materials in parts by weight: 100 parts of IR, 40-44 parts of carbon black N326, 25-27 parts of ISAF, 9-11 parts of zinc oxide, 0.4-0.6 parts of stearic acid, 1.5-2.5 parts of petroleum resin, 0.4-0.7 part of anti-ageing agent RD, 0.2-0.4 part of cobaltous naphthenate, 0.3-0.5 parts of anti-scorching agent CTP, 2.4-3.1 parts of third vacuum side distillate oil, 4.3-5.2 parts of tert-butyl-phenolic curing resin, 2.1-2.4 parts of sulfur, and 0.8-1 parts of promoter NOBS. The radial-tire belt compound is matched with the performances of the cross-country fork truck with load of 5.8 t, and is adaptive to the work environment of cross-country fork trucks. The processing safety of the belt compound is improved, the bonding performance of the belt compound material with a steel cord is improved, and the yield and the quality of a tyre are improved.

Description

technical field [0001] The invention belongs to the technical field of tire rubber, and in particular relates to a radial tire belt rubber for a 5.8-ton off-road forklift and a preparation method thereof. Background technique [0002] Off-road forklifts are equipment for loading and unloading materials in airports, docks, stations and other material distribution centers with poor road conditions. They have good mobility and reliable cross-country performance. The speed of off-road forklifts is higher than that of ordinary forklifts, and its mobility is obvious; the engine power is large and the off-road performance is high. [0003] The rubber used in the belt layer of off-road forklift radial tires needs to have the following basic requirements: high tear strength; good fatigue resistance; good adhesion to cords. But the sizing material of the belt layer rubber has poor safety performance in the processing process at present, and the bonding performance of the sizing mater...
