Abstract
The invention discloses reinforced butadiene styrene rubber which comprises butadiene, styrene and additives, wherein butadiene accounts for 31.5-43% of the weight of the reinforced butadiene styrene rubber; styrene accounts for 34.5-46% of the weight of the reinforced butadiene styrene rubber; the additives account for 11-22.5% of the weight of the reinforced butadiene styrene rubber; the additives comprise an antioxidant, a wear-resisting agent, a reinforcing agent, a vulcanization accelerator and a filling agent. In such a mode, the reinforced butadiene styrene rubber disclosed by the invention adopts a plurality of additives, through scientific proportioning, the strength and oxidation resistance of the prepared reinforced butadiene styrene rubber are remarkably improved; moreover, the reinforced butadiene styrene rubber is rapid in vulcanization in the production process, high in production efficiency, long-lasting and durable and high in performance cost ratio.
Description
Technical field
The present invention relates to rubber compounding field, particularly relate to a kind of styrene-butadiene rubber(SBR) of strengthening.
Background technology
Rubber is a kind of resilient polymkeric substance, and according to the difference of making mode, rubber can be divided into synthetic rubber and natural rubber two classes.Natural rubber is mainly derived from para ruber, when the epidermis of this rubber tree is cut open, will flow out milky juice, is called latex, latex through cohesion, washing, moulding, be drying to obtain natural rubber.Synthetic rubber is made by artificial synthesis under the inspiration of natural rubber, adopts different monomers can synthesize different types of rubber.Nowadays elastomeric output, considerably beyond the output of natural rubber, particularly styrene-butadiene rubber(SBR), is maximum general purpose synthetic rubber kind.
Styrene-butadiene rubber(SBR) is one of rubber of realizing the earliest suitability for industrialized production, it is divinyl and cinnamic random copolymers, its physical mechanism performance, the use properties of processing characteristics and goods is close to natural rubber, can and use with natural rubber and various synthetic rubber, be widely used in the fields such as the production of tire, adhesive tape, sebific duct, electric wire, medical apparatus and various rubber items, but the intensity of pure styrene-butadiene rubber(SBR) is low, winter hardiness is also slightly poor, vulcanization rate is slow, and crack propagation velocity is fast, hot tear crack poor performance.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of styrene-butadiene rubber(SBR) of strengthening, and intensity is high, and sulfuration is fast, and anti-oxidant, wearing quality is good.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of styrene-butadiene rubber(SBR) of strengthening is provided, comprise: divinyl, vinylbenzene and additive, described divinyl accounts for 31.5% ~ 43% in reinforcement styrene-butadiene rubber(SBR), described vinylbenzene accounts for 34.5% ~ 46% in reinforcement styrene-butadiene rubber(SBR), described additive accounts for 11% ~ 22.5% in reinforcement styrene-butadiene rubber(SBR), described additive comprises oxidation inhibitor, anti-wear agent, strengthening agent, vulcanization accelerator, weighting agent, described oxidation inhibitor accounts for 5% ~ 9% in additive, described anti-wear agent accounts for 21% ~ 25% in additive, described strengthening agent accounts for 20% ~ 24% in additive, described vulcanization accelerator accounts for 6% ~ 10% in additive, described weighting agent accounts for 32% ~ 36% in additive.
In a preferred embodiment of the present invention, described oxidation inhibitor accounts for 9% in additive.
In a preferred embodiment of the present invention, described anti-wear agent accounts for 24% in additive.
In a preferred embodiment of the present invention, described strengthening agent accounts for 22% in additive.
In a preferred embodiment of the present invention, described vulcanization accelerator accounts for 10% in additive.
In a preferred embodiment of the present invention, described weighting agent accounts for 35% in additive.
The invention has the beneficial effects as follows: the one that the present invention points out is strengthened styrene-butadiene rubber(SBR), spy has adopted multiple additives, through the proportioning of science, the reinforcement styrene-butadiene rubber(SBR) making intensity and anti-oxidant aspect obviously improve, and in production process, vulcanization rate is fast, production efficiency is high, durable in use, and cost performance is high.
