abstact a sulfur-vulcanizable rubber composition obtained by thermomechanical working of a conjugated diene compound and an aromatic vinyl compound prepared by solution polymerization in a hydrocarbon solvent having a total content of aromatic vinyl compound of between 5% and 50% and a glass transition temperature(Tg) of between 0℃ and -80℃ with 30 to 150 parts by weight per 100 prats by weight of elastomer of a silica having a BET surface area of between 100 and 250 m2/g , a CTAB surface area of between 100 and 250 m2/g , an oil absorption measured in DBP of between 150 and 250 ml/100g , and an average projected area of the aggregates greater than 8500 nm2 before use and between 7000 and 8400 nm2 after thermomechanical mixing as well as the additives conventionally employed, with the exception of sulfur vulcanization system, comprising at least one heat step reaching a temperature of between 130℃ and 180℃ for a suitable period of time of between 10 seconds and 20 minutes which is a function of the temperature selected in order to carry out the mechanical work and of the nature and volume of the components subjected to the mechanical work, followed by a finishing step consisting of the incorporating of the vulcanization system by mechanical work at a temperature below the vulcanization temperature . BACKGROUND OF THE INVENTION The object of the present invention is a sulfur-vulcanizable rubber composition having a base of a copolymer conjugated diene and an aromatic vinyl compound preferably having silica as majority filler , which can be used for the manufacture of high-performance tires in all seasons. Since saving in fuel and the battle against nuisances created by motor vehicles have become a priority ,the purpose of the designer of tires is to produce a tires which has both very little rolling resistance , excellent adherence both to dry ground and to wet and snow-covered ground ,very good resistance to wear and,finally ,reduced noise of travel. Numerous solutions have been proposed in order to decrease the rolling resistance of tires, in particular by modifying the rubber compositions used for the treads of the tires. Thus, for rubber compositions which are reinforced with carbon black, it was initially proposed to reduce the content of carbon black. It was then proposed, as in U.S. Pat. No. 4,822,844, to use a carbon black having specific iodine absorption surface (IA) and nitrogen absorption surface (N2SA), as well as by an average size of well-defined carbon particles . Another solution descried in U.S. Pat. No. 4,866,131 proposed the use as tread composition of a copolymer of butadiene and styrene prepared in solution and of low molecular weight in mixture with another conventional copolymer prepared in solution or emulsion .Finally , in U.S. Pat. No. 4,894,420, it was propose to use a tread formed of a blend of cis 1,,4-polyisoprene and a diene / acrylonitrile copolymer . However , none of the solutions proposed up to now has proven satisfactory since the improvement in the rolling resistance is accompanied by a decrease in one or more essential properties , such as the reduction of adherence on wet and / or snow-covered ground or a reduction in the resistance to swear, and, furthermore, all of these solutions are always fully dependent on petroleum . It has also been proposed to use as reinforcing fillers white fillers such as silica, benatonite , clay, titanium oxide, talc,etc., which have the advantage of not being obtained from petroleum and of decreasing the resistance to travel of the tires having a tread comprising such fillers. However , the use of silica in tread compositions has still remained an exception and has frequently represented only a minority fraction of the total filler as described in U.S. Pat. No. 4,894,420 and U.S. Pat. No. 4,820,751 in view of the resultant decline in the properties, in particular the decline in the resistance to wear. In order to remedy this situation , European Patent Application 299 074 proposed a rubber composition comprising silica as reinforcing filler in very large proportions and which is based on a polymer which is functionalized by means of a special alkoxy silane compound having a non-hydrolyzable alkoxy group. However, this solution is restrictive in that it permits the use only of a very specific family of silanes, which constitutes a handicap for industrial use. |

US0052274425A 摘要 通過一種共軛二烯化合物和一種芳族乙烯系化合物的熱機械加工得到一種可硫化橡膠組合物,其中的芳族乙烯系化合物是通過于一種含有總含量為5%到50%的芳族乙烯系化合物,玻璃化溫度(Tg)為0℃到80℃,與每100重量份彈性體中30到150重量份的具有BET表面積100到250m2/g、CTAB表面積為100到250 m2/g、按DBP計量吸油量為150到250 ml/100g的二氧化硅于碳氫化合物溶劑中進行溶液法聚合而制備的,這種摻合料的平均投影面積在使用之前大于8500 nm2,在熱機械混合之后為7000到8400 nm2之間,而且除硫化體系之外按常規(guī)使用添加劑, 其中至少包括一個步驟于130℃到180℃溫度加熱10秒鐘到20分鐘的時段,選擇這個溫度涵數(shù)是為了進行機械作業(yè)以及經(jīng)受這種機械作業(yè)的這些組分的性質(zhì)和量,隨后一個加工步驟包括于低于硫化溫度的溫度下通過機械作業(yè)加入硫化體系。 發(fā)明的背景 本發(fā)明的目的是一種具有共聚物共軛二烯和芳族乙烯系化合物為基礎(chǔ),最好含有二氧化硅作為主要填料的可硫化橡膠組合物,這種橡膠組合物可以用于制造一年四季都能使用的高性能輪胎。因為節(jié)約燃料和與機動車事故作斗爭已經(jīng)成為最重要的問題,the輪胎設(shè)計者的目的是要生產(chǎn)一種不論對干地面還是濕地面和冰雪覆蓋的地面都具極小滾動阻力,the極好附著力而且兼具很好的耐磨性,the最終減少行進的噪音的輪胎。提出了許多減小輪胎滾動阻力的解決方案,特別是提出了通過改進用于輪胎面花紋的橡膠組合物的方案。 因而,對于炭黑補強的橡膠組合物,最初是打算減少炭黑含量。后來美國專利4,822,844提出了使用具有特殊的碘吸收表面(IA)和氮吸收表面(N2SA),而且明確規(guī)定了碳粒子平均粒度的炭黑。另一個解決方案是于美國專利4,866,131中提出的,用作外胎面組成物的是丁二烯和苯乙烯于溶液中和低分子量混合物中與另一個傳統(tǒng)的于溶液乳液中制備的共聚物的共聚物。最后,美國專利4,894,420中提出使用由順式1,,4 -聚異戊二烯和二烯/丙烯腈共聚物混合物形成的外胎面。然而,到目前為止提出的這些解決方案都沒有被證明是令人滿意的,這是由于滾動阻力的改善卻伴隨有基本性能的降低,比如,減少了對濕地面及/或覆雪地面的附著力,或降低發(fā)誓性,此外,所有這些解決方案總是要完全地依賴石油。還提出了作為增強填充料使用的白色填料,比如二氧化硅、粘土、二氧化鈦、滑石,等等,這些填料的優(yōu)點在于不是來自于石油,并且這種外胎面包含此類填料的輪胎還減少了行進阻力。然而,外胎面組成物中使用二氧化硅仍然是一個例外,如在美國專利4,894,420和4,820,751中所述由于會造成性能下降特別是耐磨性下降,因而這常常僅代表全部填料的少數(shù)部分。為了改善這種狀況歐洲申請專利299074提出了一種其中包含很大比例的二氧化硅作為增強填充料的橡膠組合物,這是基于一種通過專用的帶有不可水解烷氧基的烷氧基硅烷化合物功能化的聚合物。然而,這些解決方案局限于僅僅允許使用非常專門種類的硅烷,這就防礙了工業(yè)上的應(yīng)用。 |
