Low-temperature-resistant farm paddy field tire thread formula

Abstract

The invention discloses a low-temperature-resistant farm paddy field tire thread formula which comprises, by weight, 40-60 parts of SMR20, 40-60 parts of BR9000, 45-55 parts of N220, 1-8 parts of winter tire low-temperature material L-730, 1-5 parts of stearic acid, 1-8 parts of zinc oxide, 0.5-3 parts of antioxidant RD, 0.5-3 parts of antioxidant 4020, 0.5-3 parts of protective wax, 3-9 parts of aromatic hydrocarbon and 0.5-2 parts of accelerators NS, D and 1-2 parts of common sulfur. Through low-temperature-resistant farm paddy field tire test and application, it is proved that the formula has the advantages of being excellent in process, low in low-temperature hardness, excellent in ice and snow ground holding force, low in glass transition temperature, excellent in slip resistance and the like; through contrast tests in different rubber systems, it is shown that the performance of prepared tires is consistent, even under the lower-temperature working environment, the sizing material is made to keep good elasticity, tire crack under the severe cold condition can be prevented effectively, the use performance of paddy field tires is improved in severe cold areas, tire manipulation safety is improved, the feature requirements of four-season paddy field tires are fully met.

Description

technical field [0001] The invention relates to a low-temperature resistant agricultural paddy tire tread formula, which belongs to the technical field of tire manufacturing. Background technique [0002] Paddy tires are a kind of agricultural tires, also known as high flower agricultural tires, mainly used for paddy field operations. Rice planting in Northeast my country mainly relies on paddy field tires; due to the relatively cold weather in Northeast China, the performance of paddy field tires generally decreases due to low temperature crystallization when used in severe cold areas, resulting in paddy field tires working in severe cold areas when the temperature is low. Severe cracks and root cracks appear. Faced with ice, snow and low temperatures, the requirements and demands on winter tires are increasing. In order to specially develop the low temperature resistant agricultural paddy tire tread formula and apply it in the factory. The applied tires and rubber produc...
