Abstract

The invention relates to a tyre-repairing adhesive for giant engineering machines and a preparation method thereof. The tyre-repairing adhesive for the giant engineering machines takes natural rubber and reinforcing carbon black as main components which are properly matched with a softener, a binding agent, an activator, an antioxidant, a vulcanizing agent, an accelerator and a scorch retarder, and is obtained by twice of mixing and milling by a rubber internal mixer. The tyre-repairing adhesive for the giant engineering machines prepared by the formula and the method is characterized by low temperature but quick vulcanizing and stable storage, can also obtain excellent balance between toughness, calorific value, thermal aging property and wearing resistance and between the tyre-repairingadhesive and the binding performance of the tyre body, and is particularly suitable for the adhesive used for repairing tyres of the giant engineering machines.

Description

(1) Technical field: [0001] The invention relates to a tire repair rubber, in particular to a giant engineering machinery tire repair rubber and a preparation method thereof. (two) background technology: [0002] Giant off-road tires are mainly used in large-scale open-pit mines. Due to poor road conditions and harsh operating conditions, the crown and sidewall of giant off-road tires are easily cut and stabbed by sharp ore. In order to prevent early scrapping of giant off-road tires, the extension For the purpose of driving life of giant off-road tires, these wounds need to be repaired. According to the special use environment of giant off-road tires, the repair rubber itself is required to have wear resistance, low heat generation, excellent anti-aging performance, and good adhesion performance with giant off-road tires, so as to ensure The repaired giant OTR tires still have good performance. At present, there are few reports on tire repair rubber, especially tire repai...
