Description

本発明は、分子内両末端にオルガノオキシシリル基を持ち、更に分子内にポリスルフィド基を含んだ2価炭化水素鎖で連結された有機珪素化合物を含有し、ゴムに配合した際のアルコール発生量が少ないゴム用配合剤、及びその化合物と少なくとも1種の粉体とを含有してなるゴム用配合剤に関するものである。   The present invention comprises an organosilicon compound having an organooxysilyl group at both ends in the molecule and further linked by a divalent hydrocarbon chain containing a polysulfide group in the molecule, and the amount of alcohol generated when blended with rubber The present invention relates to a rubber compounding agent and a rubber compounding agent comprising the compound and at least one powder.

従来から、アルコキシシリル基とポリスルフィド基を分子内に含む化合物は知られている。これらの化合物は、シリカ、水酸化アルミニウム、タルク、クレー等の無機材料と熱可塑性樹脂、熱硬化性樹脂、ゴム等の有機材料との界面結合剤や、無機基材へのゴムの接着改良剤、プライマー組成物等に応用されている。   Conventionally, compounds containing an alkoxysilyl group and a polysulfide group in the molecule are known. These compounds include interfacial binders between inorganic materials such as silica, aluminum hydroxide, talc and clay and organic materials such as thermoplastic resins, thermosetting resins and rubbers, and rubber adhesion improvers for inorganic substrates. And applied to primer compositions and the like.

また、各種ゴムにシリカを配合したゴム組成物も知られており、例えば低発熱性で耐摩耗性などに優れたタイヤトレッド用ゴム組成物として使用されている。このような組成物に対しては、アルコキシシリル基とポリスルフィド基を分子内に含む化合物、例えば、bis−トリエトキシシリルプロピルテトラスルフィドやbis−トリエトキシシリルプロピルジスルフィド等が有効であることが、従来より知られていた。しかし、これらの化合物を使用した場合、ゴム混練時に発生するアルコール量が多いため、引火の危険があるという問題があった。   Further, rubber compositions in which silica is blended with various rubbers are also known. For example, they are used as rubber compositions for tire treads having low heat buildup and excellent wear resistance. For such a composition, a compound containing an alkoxysilyl group and a polysulfide group in the molecule, for example, bis-triethoxysilylpropyl tetrasulfide or bis-triethoxysilylpropyl disulfide is effective. It was more known. However, when these compounds are used, there is a problem that there is a danger of ignition because of the large amount of alcohol generated during rubber kneading.

上記した平均組成式(1)で表される有機珪素化合物は、加水分解して生成するアルコール量が少ないものであり、10質量%KOH−ブタノール溶液中で加水分解させたときに発生するアルコール量は、有機珪素化合物の平均分子量に対して49質量%以下であり、好ましくは40質量%以下であり、より好ましくは35質量%以下である。アルコール発生量が、上記量を超えるとゴム混練中に発生するアルコール量が多くなり、安全面、作業環境面及び環境汚染面から好ましくない。
更に、p及びrがともに2の場合には、上記有機珪素化合物から発生するアルコール量は、有機珪素化合物の平均分子量に対して30質量%以下が好ましく、より好ましくは25質量%以下である。なお、アルコール量の下限は通常0.1質量%以上である。
The organosilicon compound represented by the above average composition formula (1) has a small amount of alcohol produced by hydrolysis, and the amount of alcohol generated when hydrolyzed in a 10% by mass KOH-butanol solution. Is 49% by mass or less, preferably 40% by mass or less, and more preferably 35% by mass or less with respect to the average molecular weight of the organosilicon compound. If the amount of alcohol generated exceeds the above amount, the amount of alcohol generated during rubber kneading increases, which is not preferable from the viewpoint of safety, work environment, and environmental contamination.
Further, when both p and r are 2, the amount of alcohol generated from the organosilicon compound is preferably 30% by mass or less, more preferably 25% by mass or less, based on the average molecular weight of the organosilicon compound. In addition, the minimum of the amount of alcohol is 0.1 mass% or more normally.

ここで、10質量%KOH−ブタノール溶液中で式(1)の有機珪素化合物を加水分解させる方法として、より具体的には、本化合物を蒸留装置に仕込み、そこに10質量%KOH−ブタノール溶液を加えればよく、温度は特に限定されないが室温以下でよく、好ましくは0℃〜20℃程度でよく、反応時間も特に限定されないが、10分〜1時間程度でよい。また10質量%KOH−ブタノール溶液を蒸留装置に仕込み、そこに本化合物を加えてもよく、この場合、温度は特に限定されないが室温以下でよく、好ましくは0℃〜20℃程度でよく、反応時間も特に限定されないが、10分〜1時間程度でよい。   Here, as a method for hydrolyzing the organosilicon compound of the formula (1) in a 10% by mass KOH-butanol solution, more specifically, this compound is charged into a distillation apparatus, and there is a 10% by mass KOH-butanol solution. The temperature is not particularly limited but may be room temperature or lower, preferably about 0 ° C. to 20 ° C., and the reaction time is not particularly limited, but may be about 10 minutes to 1 hour. Further, a 10% by mass KOH-butanol solution may be charged into a distillation apparatus, and this compound may be added thereto. In this case, the temperature is not particularly limited, but may be room temperature or less, preferably about 0 ° C. to 20 ° C. Although the time is not particularly limited, it may be about 10 minutes to 1 hour.

生成したアルコール量を測定する方法としては、加水分解させた液をそのままガスクロマトグラフィー分析してもよく、発生したアルコールを留去して、留去したアルコール−ブタノール混合液をガスクロマトグラフィー分析して測定してもよい。

本発明のゴム用配合剤は、平均組成式(1)で表される有機珪素化合物(A)を、予め少なくとも1種の粉体(B)と混合したものをゴム用配合剤として使用することも可能である。粉体(B)としては、カーボンブラック、タルク、炭酸カルシウム、ステアリン酸、シリカ等を挙げることができる。   The rubber compounding agent of the present invention is prepared by mixing an organosilicon compound (A) represented by the average composition formula (1) with at least one powder (B) in advance as a compounding agent for rubber. Is also possible. Examples of the powder (B) include carbon black, talc, calcium carbonate, stearic acid, and silica.

粉体(B)の配合量は、成分(A)/(B)の質量比で70/30〜5/95、更に好ましくは60/40〜30/70の割合である。粉体(B)の量が少な過ぎると、ゴム用配合剤が液状となり、ゴム混練機へ仕込みづらくなる場合がある。逆に多過ぎるとゴム用配合剤の有効量に対して全体量が多くなるため、輸送費用が高くなる場合がある。   The blending amount of the powder (B) is a ratio of 70/30 to 5/95, more preferably 60/40 to 30/70, as a mass ratio of the component (A) / (B). If the amount of the powder (B) is too small, the rubber compounding agent becomes liquid, and it may be difficult to prepare the rubber kneader. On the other hand, if the amount is too large, the total amount increases relative to the effective amount of the rubber compounding agent, which may increase the transportation cost.

本発明のゴム用配合剤は、脂肪酸、脂肪酸塩、ポリエチレン、ポリプロピレン、ポリオキシアルキレン、ポリエステル、ポリウレタン、ポリスチレン、ポリブタジエン、ポリイソプレン、天然ゴム、スチレン−ブタジエン共重合体ゴム等の有機ポリマーやゴムと混合されたものでもよく、加硫又は架橋剤、加硫又は架橋促進剤、各種オイル、老化防止剤、充填剤、可塑剤などのタイヤ用、その他一般ゴム用に一般的に配合されている各種添加剤を配合してもよく、その形態として、液状でも固体状でもよく、更に有機溶剤に希釈したものでもよく、またエマルジョン化したものでもよい。   The rubber compounding agent of the present invention includes fatty acid, fatty acid salt, polyethylene, polypropylene, polyoxyalkylene, polyester, polyurethane, polystyrene, polybutadiene, polyisoprene, natural rubber, styrene-butadiene copolymer rubber and other organic polymers and rubber.

本発明のゴム用配合剤は、シリカ配合のゴム組成物に対して好適に用いられる。
この場合、上記ゴム用配合剤の添加量は、ゴム組成物に配合されるフィラー100質量部に対し、平均組成式(1)で表される有機珪素化合物成分又は(A)成分を0.2〜30質量部、特に好ましくは1.0〜20質量部添加するのが望ましい。平均組成式(1)で表される有機珪素化合物の配合量が少な過ぎると所望の効果が得られない場合がある。また、配合量が多すぎるとゴム混練中にアルコール発生量を低下させる目的を達成できないおそれがある。
The rubber compounding agent of the present invention is suitably used for a rubber composition containing silica.
In this case, the addition amount of the rubber compounding agent is 0.2 parts by weight of the organosilicon compound component or the component (A) represented by the average composition formula (1) with respect to 100 parts by mass of the filler compounded in the rubber composition. It is desirable to add -30 parts by mass, particularly preferably 1.0-20 parts by mass. If the amount of the organosilicon compound represented by the average composition formula (1) is too small, the desired effect may not be obtained. Moreover, when there are too many compounding quantities, there exists a possibility that the objective which reduces alcohol generation amount during rubber | gum kneading | mixing may not be achieved.
