Abstract
The invention provides a formula of rubber for automobile tires. The formula is composed of the following raw materials in parts by weight: 20 to 25 parts of white carbon black, 15 to 20 parts of naphthenic oil, 6 to 8 parts of zinc oxide, 10 to 15 parts of solution polymerized butadiene styrene rubber, 2 parts of anti-aging agent, and 2 to 3 parts of sulfur. The rubber has the advantages of wear resistance, low temperature resistance, low themogenesis, small rolling resistance, high tensile strength, tearing resistance, and good anti-slippery performance.
Description
Technical field
The present invention relates to a kind of chemical industry formula technique field, relate in particular to a kind of doughnut rubber compounding.
Background technology
Along with motorway, develop the quickening with car speed, the also corresponding raising of the travel speed grade of tire rapidly.The problem of bringing is the security of vehicle, to the requirement of tire, is that the grabbing property of road pavement under the prerequisite that guarantees high actual service life (tyre surface is wear-resisting) is good, and especially on rainy day wet road surface and winter ice and snow road, cling property is good.Tire wear-resisting, that rolling resistance is low, wet-sliding resistant performance is good is referred to as high-performance tire.
Traditional tread rubber is selected natural rubber, cis-1,4-polybutadiene rubber and styrene-butadiene rubber(SBR) conventionally.Cis-1,4-polybutadiene rubber rolling resistance is low, and wear resisting property is good, but wet-sliding resistant performance is very poor; Emulsion polymerized styrene butadiene rubber wet-sliding resistant performance is good, but rolling resistance is large, not wear-resisting; Natural gum performance is situated between between Yu Shunding and butadiene-styrene rubber.Accomplish both to reduce rolling resistance, guarantee high wear resistance, do not sacrifice again wet-sliding resistant performance, alone or two glue of these three kinds of glue, three-glue combination are all of no avail.
Summary of the invention
For the deficiencies in the prior art, the object of the present invention is to provide a kind of doughnut rubber compounding, this rubber has advantages of that tensile strength is high, wear-resisting, tear-resistant, anti-slippery is good.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of doughnut rubber compounding, is comprised of the raw material of following parts by weight: white carbon black 20-25 part, naphthenic oil 15-20 part, zinc oxide 6-8 part, solution polymerization styrene-butadiene rubber 10-15 part, 2 parts, anti-aging agent, sulphur 2-3 part.
As a further improvement on the present invention, anti-aging agent is N, N'-di tolyl p phenylenediamine.
The present invention adopts solution polymerization styrene-butadiene rubber, has compared not containing gel, wear-resisting, low temperature resistant the advantage that heat-dissipating is low, rolling resistance is little with emulsion polymerized styrene butadiene rubber; Compare with cis-1,4-polybutadiene rubber have cold flow not, tensile strength is high, tear-resistant, anti-slippery is good advantage; In technique, there is the advantage that rubber unvulcanizate shrinking percentage is little, extrude smooth surface, good fluidity.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.Following examples are only for technical scheme of the present invention is more clearly described, and can not limit the scope of the invention with this.
Embodiment 1
A doughnut rubber compounding, is comprised of the raw material of following parts by weight: 20 parts of white carbon blacks, 15 parts of naphthenic oils, 6 parts, zinc oxide, 10 parts of solution polymerization styrene-butadiene rubbers, 2 parts, anti-aging agent, 2 parts, sulphur; Anti-aging agent is N, N'-di tolyl p phenylenediamine.
Embodiment 2
A doughnut rubber compounding, is comprised of the raw material of following parts by weight: 25 parts of white carbon blacks, 20 parts of naphthenic oils, 8 parts, zinc oxide, 15 parts of solution polymerization styrene-butadiene rubbers, 2 parts, anti-aging agent, 3 parts, sulphur; Anti-aging agent is N, N'-di tolyl p phenylenediamine.
The above is only the preferred embodiment of the present invention, it should be pointed out that for those skilled in the art, not departing under the prerequisite of the technology of the present invention principle, can also make some improvement, and these improvement also should be considered as protection scope of the present invention.
Claims (2)
1. a doughnut rubber compounding, is characterized in that: the raw material by following parts by weight forms: white carbon black 20-25 part, naphthenic oil 15-20 part, zinc oxide 6-8 part, solution polymerization styrene-butadiene rubber 10-15 part, 2 parts, anti-aging agent, sulphur 2-3 part.
