Typically, the amount that improves this property is 100 parts (by weight) of rubber. will range from about 0.1 to 10 parts (phr). often furazanoxai is used in amounts ranging from 0.5 to 5 phr. Formulating the rubber composition of the invention The temperature used for this ranges from room temperature to temperatures commonly used in technology, e.g. 75-175°C, Or (d room temperature, -Bo'C to the commonly used temperature range of 150 to 200 °C be. Possibly a wider temperature range, e.g. from about 20°C to 220°C. Prescriptions can be made with. However, in many cases a narrower temperature range For example, a temperature of about 50 to 190°C is used. As previously mentioned, fillers, accelerators and curing and other conventional rubber additives are also often added to these precured mixtures. Included in amount.

The vulcanizate of the present invention can be prepared under the temperature and time commonly used in technology. Manufactured by curing a composition containing an oxide. Note that the present invention is not significantly dependent on such curing variables.

Typically, the rubber and filler (or pigment) are first mixed and then this mixture is Treat with furazane oxide and harden. Other orders can be used, but the rubber It is essential to thoroughly mix the agent (pigment) and furazane oxide before vulcanization.

Among the desirable and beneficial properties exhibited by the compositions of the present invention are improved additives. construction method, increased green strength and in some cases reduced viscosity. N Compositions containing substantial amounts (greater than 50%) of R, IR or CR may be It exhibits workability and increased green strength. Improved processability of uncured rubber formulations Compounding by techniques like calendering, milling, remilling, extrusion etc. and is often desirable as it saves energy and time during subsequent processing of the rubber. stomach. Such savings are important in the face of modern energy shortages and rising prices. That is. Processability generally refers to reduced viscosity and An umbrella term also used to describe high green strength.

Until now, it has been assumed that reducing the viscosity of an uncured composition also reduces its uncured strength. were often discovered. Similarly, increasing unaged strength increases viscosity. was also discovered. By the way, if the reduction in viscosity is achieved in combination with the unaged strength. This is a particularly desirable feature of the compositions of the present invention.

Generally, compositions containing SR, IR, and CR have a flow rate of about 0.5 to 1.5'IIhr. It shows a decrease in viscosity of about 20 munits relative to lasane oxide, and about 20 to 10 with an increase in green strength of 0 psj. Flaza in synthetic rubber, e.g. SBR A similar amount of carbon oxide increases the Mooney viscosity to about 10 units, while increasing the unaged strength. About 5-50 pS? , increase. When the amount of furazane oxide is increased (e.g. (e.g. 2-5 phr), extreme viscosity reduction can be achieved and it is possible to liquefy NR and JR. I can do it. Such liquid rubber can be used in sealants and with other types of rubber. Useful in combination as processing aids to help plasticize the rubber. Also Liquid rubbers known as depolymerized rubbers (DpR) are well known in the art and are There is no need to describe it further. Reduced viscosity sometimes observed in compositions of the invention is an antioxidant that appears to interact with and scavenge polymer free radicals prior to crosslinking. and enhanced by the inclusion of substances such as carbon black and silica. Ru. That is, the maximum viscosity reduction is due to furazane oxide in a given comb composition. and by adjusting the concentration of antioxidants or radical scavengers (fillers). can be achieved.

Manufacture of master patch In the following embodiments, an internal mixer such as a Brabender or a small gunbe mixer may be used. It was used. Various substances are often added to the mixer in certain proportions and as directed. Conventional techniques were used to continue mixing for a period of time. The master paper manufactured in this way Further addition and subsequent mixing were performed. The standard techniques are as follows: : Time (minutes) Addition to mixer 0 100 parts of polymer , 5 Half of the filler and furazane oxide 15 The remaining filler and zinc oxide , stearic acid: (, O processed oil 60 Drop of the cured composition at 160 to 170 degrees and then add the uncured master pad.

SB RK-based passenger car tire tread raw material composition containing antioxidants was manufactured. Furthermore 1. A similar set containing Qphr benzofurazan oxide The products were prepared under controlled conditions. The Mooney viscosity of the control material was 60.0.

Zinc chloride, antioxidants, softeners, resins, sulfenamide accelerators, sulfur and retarders An NR composition containing the following was produced. Furthermore, it contains 1phγ of benzofurazan oxide. A substantially identical composition was prepared with The control had a Mooney viscosity of 64.4. The 7 razan oxide composition also had a viscosity of 49.0. i.e. 1.0 part 7 Lasan oxide caused a decrease in viscosity of 15 units under the same mixing conditions. .

Example 4 B grade containing silica filler (approximately 80 phr B'1-sil silica) Two typical truck tire tread compositions were made from NR. to this contains normal amounts of silane cassilling agents, plasticizers, antioxidants, processing oils, sulfur, accelerators, Also included are retarders, resins and activators. Compositions without furazane oxide are i, 3, too hard to mix in the panberry, very dry when falling 1~ It exhibited stiffness and had the appearance of a saw.

A second compound of the same composition further containing 1 phr of benzofuran oxide is mixed. It fell off easily after only 6 minutes, but gave a mixture identical to the control after 12 minutes.

It fell smoothly from Panberry and was stiff and crackling.

Example 5 (A) A series of IR-based rubber compounds were prepared. This compound contains fillers and hardeners. I didn't. It is θ~2. ．． Methylbenzofuran oxide in the range of 5 phr and in some cases 2-0 phr of a commercially available antioxidant (San-1oflex 1 3). Each was mixed at 150° for 6 minutes, then the Mooney viscosity Decided. The results are shown in Table 5A. As can be understood, compounds that do not contain antioxidants viscosity increases to 15 phr of furazane oxide and then drops rapidly. I put it down. This increase is likely due to cross-linking reactions competing with molecular chain scission. . At high amounts of furazane oxide, scission outweighs crosslinking and the viscosity decreases. other The observations indicated that an increase in viscosity is unlikely to occur in the presence of carbon black.

Rather, only a constant decrease in viscosity was observed with increasing amounts of furazane oxide.

In the case of raw materials containing both furazane oxide and antioxidants, similar viscosity A constant decrease was observed. Antioxidants interfere with cross-linking, and degradation due to chain scission is evident. I think it will be white.

Typical conventional cure systems include sulfur, gas oxide, urethane and and benzoquino-7-soxime series.゛Example 6 A series of treatments using conventional carpin black-containing compositions and sulfur-based curing systems. Sulfur was produced. This vulcanizate contains about 20 parts Hi, -5il silica and the usual amount Zinc oxide 1. Antioxidants, softeners, resins, sulfenamide accelerators, sulfur and retarders It also contained a spreading agent. The first one (control) contains no accelerator, and the second one 0.6 p h r N1trol (JWonsantChem,’Co,) and a third contained LOphr benzofurazan oxide. N　i　 trcl is a known accelerator and was used in its recommended amount. Each country The evaluation data for sulfur is shown in 1i. Obviously, benzofurazan oxide Vulcanizates containing It showed no major shortcomings.

Typical compositions are too hard to mix in 1.3 to 9 panberries and drop. When lowered, it was very dry and stiff, giving it a saw-like appearance. 1 phr more The same mixture containing benzofuran oxide fell easily after only 6 minutes of mixing. However, after 12 minutes, the same mixture as the control was given. This is smooth from panberry and did not exhibit the rigidity and appearance of the controls. two compounds in the same way It was cured and evaluated by numerous carload tests. These evaluation results are shown in Table 1.

Apparently, vulcanizates containing 1 phr of benzofurazan have improved (i.e. lower) motility. The line temperature showed an increased repulsive force. Other properties due to the presence of furazane oxide did not decline significantly.
