Abstract
The invention relates to a tyre, particularly relates to a cold-resistant tyre for paddy field, and belongs to the technical field of rubber processing. In order to improve the phenomenon of low-temperature crystallization of natural rubber in a formula, through adding butadiene rubber with better low-temperature performance and an aliphatic ester softening agent in a tread rubber formula of the tyre for the paddy field, the distance between runner chains in the tread rubber of the tyre for the paddy field is increased, thus the molecular chain flexibility is improved, and the low-temperature brittleness temperature of the tread rubber of the tyre for the paddy field is reduced, and thus the low-temperature resistance of the tyre for the paddy field in a severe cold area is improved.
Description
Technical field
The present invention relates to a kind of tire, be specifically related to a kind of cold-resistant paddy field tire, belong to the Rubber processing technical field.
Background technology
At present, in the tire use of severe cold area paddy field, the degradation that natural rubber in the tire tread glue causes because of low temperature crystallization at severe cold area, thus when causing the paddy field tire to be worked under the lower situation of severe cold area temperature, the paddy field tire serious be full of cracks and root occur and splits phenomenon.
Summary of the invention
The objective of the invention is in order to overcome above-mentioned the deficiencies in the prior art part, a kind of cold-resistant paddy field tire is provided, for improving the low temperature crystallization phenomenon of natural gum in the prescription, by in paddy field tire tread glue prescription, adding low-temperature performance divinyl rubber and fatty acid ester tenderizer preferably, make that the distance between the rubber chain increases in the tire tread glue of paddy field, thereby improve the chain flexibility of molecule, reduce paddy field tire tread compound low temperature brittleness temperature, thereby improve the resistance to low temperature of severe cold area paddy field tire.
The present invention realizes with following technical scheme: a kind of cold-resistant paddy field tire, it is characterized in that: by in the tire tread glue formulation of paddy field, adding good divinyl rubber and the fatty acid ester tenderizer of low-temperature performance, make that the distance between the rubber chain increases in the tread rubber, thereby improve the chain flexibility of molecule, reduce paddy field tire tread compound low temperature brittleness temperature, improve its resistance to low temperature; Described tread rubber comprises one section glue and finished composition, and wherein the prescription of one section glue and weight part are: 20# standard glue 30-35; Styrene-butadiene rubber(SBR) 45-50, divinyl rubber (cis-butadiene cement) 20, zinc oxide 4-6, stearic acid 2-4, anti-aging agent 3-4, protection wax 1.5-2, in super carbon black N220 50-60, fatty acid ester tenderizer (low condensation point softening oil) 5-6, binder resin 7-9, homogeneous phase agent 2-4; The prescription of finished composition and weight part are: rubber master batch 174.5-195, sulphur 2.5-3, accelerant N OBS1-2, anti-scorching agent CTP 0.3-1.
Advantage of the present invention is: according to the environment of severe cold area paddy field tire working, the aromatic hydrocarbon oil that the softening system of the tyre industry master that breaks the normal procedure is generally used, adopt the lower rubber filling oil of zero pour, even under the Working environment of lesser temps, still make sizing material keep elasticity preferably, thereby avoid the be full of cracks and the root of severe cold area paddy field tire to split phenomenon, improve the use properties of severe cold area paddy field tire.
