Description
本発明は、ゴム組成物に関する。より詳しくは、伝動ベルトや空気バネ、シール、パッキン、防振材、ホース等に用いられるゴム製品の材料として好適な、ゴム成分としてクロロプレン系ゴムを含有するゴム組成物、該ゴム組成物の加硫物及び加硫成形体に関する。 The present invention relates to a rubber composition. More specifically, a rubber composition containing chloroprene rubber as a rubber component, which is suitable as a material for rubber products used for power transmission belts, air springs, seals, packings, vibration isolators, hoses, etc., and addition of the rubber composition The present invention relates to a sulfide and a vulcanized molded body.
クロロプレン系ゴムは、機械特性や耐オゾン性、耐薬品性に優れており、その特性を活かして自動車部品、接着剤、各種工業ゴム部品など広範囲な分野に用いられている。また、近年、工業用ゴム部品に要求される性能が著しく高まっており、前述した機械特性や耐オゾン性、耐薬品性の向上に加えて、優れたゴムの加工安定性や耐熱性、耐寒性、圧縮永久歪みなども求められている。 Chloroprene-based rubber is excellent in mechanical properties, ozone resistance, and chemical resistance, and is used in a wide range of fields such as automobile parts, adhesives, and various industrial rubber parts by taking advantage of the characteristics. In recent years, the performance required for industrial rubber parts has been remarkably increased. In addition to the improvements in mechanical properties, ozone resistance, and chemical resistance described above, excellent rubber processing stability, heat resistance, and cold resistance are also provided. Also, compression set is required.
前述した要求特性を満たすため、例えば、クロロプレン系ゴムに天然ゴムとスチレン・ブタジエン共重合体をブレンドし、特定の加硫促進剤で加硫することにより、機械的強度と圧縮永久歪みを改善する技術(特許文献1参照)や、加硫物の耐熱性及び圧縮永久歪みを改善するため、クロロプレンゴムを有機過酸化物と共架橋剤とを使用して加硫する技術(特許文献2参照)も提案されている。 In order to satisfy the above-mentioned required characteristics, for example, chloroprene rubber is blended with natural rubber and styrene-butadiene copolymer and vulcanized with a specific vulcanization accelerator to improve mechanical strength and compression set. Technology (see Patent Document 1) and technology for vulcanizing chloroprene rubber using an organic peroxide and a co-crosslinking agent in order to improve heat resistance and compression set of the vulcanizate (see Patent Document 2) Has also been proposed.
しかしながら、特許文献1及び2に記載される技術だけでは、耐オゾン性や機械的強度、加工安定性などのいずれかが劣るという問題点がある。例えば、クロロプレンゴムに天然ゴムをブレンドすると機械的強度は改善されるが、耐オゾン性が悪化する場合がある。また、クロロプレンゴムに有機過酸化物を使用すると圧縮永久歪みは改善されるが、加工安定性が著しく悪化する。このため、機械的強度と加工安定性が良好で、かつ圧縮永久歪みにも優れたゴム組成物が求められていた。 However, only the techniques described in Patent Documents 1 and 2 have a problem that any one of ozone resistance, mechanical strength, processing stability, and the like is inferior. For example, blending natural rubber with chloroprene rubber improves mechanical strength, but ozone resistance may deteriorate. Further, when an organic peroxide is used for the chloroprene rubber, the compression set is improved, but the processing stability is remarkably deteriorated. For this reason, there has been a demand for a rubber composition having good mechanical strength and processing stability and excellent compression set.
そこで、本発明は、クロロプレン系ゴム分野において、機械的強度と高温条件下での圧縮永久歪みが良好で、かつ加工安定性にも優れたゴム組成物、その加硫物及び成形体を提供することを主目的とする。 Accordingly, the present invention provides a rubber composition, a vulcanized product, and a molded product thereof that have good mechanical strength and compression set under high temperature conditions and excellent processing stability in the field of chloroprene rubber. The main purpose.
本願発明者らは、前記課題を解決するために、クロロプレン系ゴムと併用する成分について、鋭意研究を行った結果、可塑剤であるリン酸系化合物が、機械的強度及び高温条件下での圧縮永久歪みを改善させることを見出した。しかし、その反面で、加工安定性が低下してしまうことが分かった。そして更に研究を重ねた結果、加硫速度を調整する化合物の中で、特定量のベンズイミダゾール系化合物及びN−シクロヘキシルチオフタルイミドの少なくとも一方を併用し、かつ、リン酸系化合物の配合量も特定の範囲とすることで、機械的強度及び高温条件下での圧縮永久歪みを改善させつつ、加工安定性も向上させることに成功し、本発明を完成させるに至った。 In order to solve the above-mentioned problems, the inventors of the present invention conducted extensive research on the components used in combination with the chloroprene rubber, and as a result, the phosphoric acid compound as a plasticizer was compressed under mechanical strength and high temperature conditions. It has been found that permanent set is improved. However, on the other hand, it has been found that the processing stability is lowered. As a result of further research, among the compounds that adjust the vulcanization rate, a specific amount of benzimidazole compound and / or N-cyclohexylthiophthalimide is used in combination, and the amount of phosphate compound is also specified. By setting it as the range of this, it succeeded in improving process stability, improving the mechanical strength and the compression set under high temperature conditions, and came to complete this invention.

In addition, embodiment described below shows an example of typical embodiment of this invention, and, thereby, the range of this invention is not interpreted narrowly.

Moreover, in addition to each component mentioned above, an antioxidant, carbon black, a softening agent, a filler, etc. can also be mix | blended with the rubber composition of this embodiment. Hereinafter, each component will be described in detail.
[クロロプレン系ゴム]
ゴム成分を構成するクロロプレン系ゴムは、クロロプレンを主成分とする原料単量体を重合した後、必要に応じて洗浄や乾燥を行うことにより得られ、重合反応の生成物である。クロロプレン単独重合体又はクロロプレンと他の単量体との共重合体の他に、重合時に添加された乳化剤、分散剤、触媒、触媒活性化剤、連鎖移動剤及び重合禁止剤などが含まれている場合がある。
[Chloroprene-based rubber]
The chloroprene rubber constituting the rubber component is obtained by polymerizing a raw material monomer containing chloroprene as a main component and then washing and drying as necessary, and is a product of a polymerization reaction. In addition to chloroprene homopolymers or copolymers of chloroprene and other monomers, emulsifiers, dispersants, catalysts, catalyst activators, chain transfer agents and polymerization inhibitors added during polymerization are included. There may be.
クロロプレンと共重合可能な単量体としては、例えば、メチルアクリレート、エチルアクリレート、ブチルアクリレート、イソブチルアクリレート、2−エチルヘキシルアクリレート、2−メトキシエチルアクリレートなどのアクリル酸エステル類、メチルメタクリレート、ブチルメタクリレート及び2−エチルヘキシルメタクリレートなどのメタクリル酸エステル類、2−ヒドロキシエチル(メタ)アクリレート、2−ヒドロキシメチル(メタ)アクリレート及び2−ヒドロキシプロピル(メタ)アクリレートなどのヒドロキシ(メタ)アクリレート類、並びに2,3−ジクロロ−1,3−ブタジエン、1−クロロ−1,3−ブタジエン、ブタジエン、イソプレン、エチレン、スチレン、アクリルアミド、ジメチルアクリルアミド及びアクリロニトリルなどが挙げられる。これらの中でも、2,3−ジクロロ−1,3−ブタジエン、アクリロニトリル、アクリルアミド、ジメチルアクリルアミド、ブチルアクリレート、2−エチルヘキシルアクリレート、2−メトキシエチルアクリレート、スチレンがより好ましい。 Examples of the monomer copolymerizable with chloroprene include acrylic acid esters such as methyl acrylate, ethyl acrylate, butyl acrylate, isobutyl acrylate, 2-ethylhexyl acrylate, and 2-methoxyethyl acrylate, methyl methacrylate, butyl methacrylate, and 2 -Methacrylic esters such as ethylhexyl methacrylate, hydroxy (meth) acrylates such as 2-hydroxyethyl (meth) acrylate, 2-hydroxymethyl (meth) acrylate and 2-hydroxypropyl (meth) acrylate, and 2,3- Dichloro-1,3-butadiene, 1-chloro-1,3-butadiene, butadiene, isoprene, ethylene, styrene, acrylamide, dimethylacrylamide and acrylic Ronitoriru and the like. Among these, 2,3-dichloro-1,3-butadiene, acrylonitrile, acrylamide, dimethylacrylamide, butyl acrylate, 2-ethylhexyl acrylate, 2-methoxyethyl acrylate, and styrene are more preferable.
なお、クロロプレンと共重合する単量体は、1種類に限定されるものではなく、例えばクロロプレンを含む2種以上の単量体を共重合したものを使用することもできる。また、クロロプレン共重合体のポリマー構造は、特に限定されるものではなく、ブロック共重合体あるいは、統計的共重合体でもよい。 In addition, the monomer copolymerized with chloroprene is not limited to one type, For example, what copolymerized the 2 or more types of monomer containing chloroprene can also be used. The polymer structure of the chloroprene copolymer is not particularly limited, and may be a block copolymer or a statistical copolymer.
例えば、アクリロニトリルとクロロプレンとの統計的共重合体は、重合反応開始後にクロロプレンを連続添加又は10回以上間欠分添することにより製造される。その際、重合反応開始時の時刻をt(0)、nを1以上の整数として、時刻t(n−1)と時刻t(n)との間の時間dt(n)におけるクロロプレンとアクリロニトリルの重合転換量の総量に基づいて、時刻t(n)と時刻t(n+1)との間の時間dt(n+1)におけるクロロプレンの添加量を決定し、未反応のクロロプレンとアクリロニトリルとの比を一定に保つことを特徴とする。 For example, a statistical copolymer of acrylonitrile and chloroprene is produced by continuously adding chloroprene or intermittently adding 10 or more times after the start of the polymerization reaction. In that case, the time of the polymerization reaction start is t (0), n is an integer of 1 or more, and chloroprene and acrylonitrile of time dt (n) between time t (n-1) and time t (n) Based on the total amount of polymerization conversion, the amount of chloroprene added at time dt (n + 1) between time t (n) and time t (n + 1) is determined, and the ratio of unreacted chloroprene to acrylonitrile is kept constant. It is characterized by keeping.
なお、上述の「統計的共重合体」は、J.C.Randall 「POLYMER SEQUENCE DETERMINATION, Carbon−13 NMR Method」 Academic Press, New York, 1977, 71−78ページに記述されているように、ベルヌーイの統計モデルにより、又は一次又は二次のマルコフの統計モデルにより、記述できる共重合体であることを意味する。アクリロニトリルとクロロプレンとの統計的共重合体は、2元系の単量体から構成される場合、下記Mayo−Lewis式(I)において、重合開始時のクロロプレン単量体とクロロプレン単量体以外のアクリロニトリル単量体との比をd[M1]/d[M2]とし、及び、クロロプレン単量体を下記Mayo−Lewis式(I)において定義されたM1とした時の反応性比r1、r2について、r1は0.3〜3000の範囲、r2は10−5〜3.0の範囲をとることが、統計学的共重合体を得るのに好ましい。 The above-mentioned “statistical copolymer” is described in J. C. Randall “POLYMER SEQUENCE DETERMINATION, Carbon-13 NMR Method” Academic Press, New York, 1977, pages 71-78. Or a linear or quadratic Markov statistical model. When the statistical copolymer of acrylonitrile and chloroprene is composed of binary monomers, in the following Mayo-Lewis formula (I), other than chloroprene monomer and chloroprene monomer at the start of polymerization Reactivity ratios r1 and r2 when the ratio to the acrylonitrile monomer is d [M1] / d [M2] and the chloroprene monomer is M1 defined in the following Mayo-Lewis formula (I) , R1 is preferably in the range of 0.3 to 3000, and r2 is preferably in the range of 10 −5 to 3.0 in order to obtain a statistical copolymer.
また、アクリル酸エステルとクロロプレンとのブロック共重合体は、アクリル酸エステル重合体のブロックと、クロロプレン重合体のブロックと、をそれぞれ1つ以上含み、下記化学式(1)又は(2)で表される構造の官能基を有する。 The block copolymer of an acrylate ester and chloroprene includes at least one block of an acrylate ester polymer and one block of a chloroprene polymer, and is represented by the following chemical formula (1) or (2). It has a functional group with a structure.
製造方法は、下記化学式(3)又は(4)で表される化合物の存在下で、アクリル酸エステル単独、又はアクリル酸エステルと他の単量体とをリビングラジカル乳化重合し、アクリル酸エステル重合体のブロックを合成した後、クロロプレン単独、又はクロロプレンと他の単量体とを混合してリビングラジカル乳化重合し、クロロプレン重合体のブロックを合成する方法と、下記化学式(3)又は(4)で表される化合物の存在下で、クロロプレン単独、又はクロロプレンと他の単量体とを分添してリビングラジカル乳化重合し、クロロプレン重合体のブロックを合成した後、アクリル酸エステル単独、又はアクリル酸エステルと他の単量体とを混合してリビングラジカル乳化重合し、アクリル酸エステル重合体のブロックを合成する方法に大別される。 In the production method, in the presence of a compound represented by the following chemical formula (3) or (4), an acrylate ester alone, or an acrylate ester and another monomer are subjected to living radical emulsion polymerization to produce an acrylate ester polymer. After synthesizing the block of the coalescence, chloroprene alone or a mixture of chloroprene and another monomer and living radical emulsion polymerization to synthesize the block of the chloroprene polymer, and the following chemical formula (3) or (4) In the presence of the compound represented by the formula, chloroprene alone, or chloroprene and other monomers are added and living radical emulsion polymerization is performed to synthesize a block of chloroprene polymer, and then acrylate ester alone or acrylic A method of synthesizing acrylic acid ester polymer block by mixing living ester emulsion polymer with acid ester and living radical emulsion polymerization Is another.
一方、クロロプレンゴムは、硫黄変性クロロプレンゴムと非硫黄変性クロロプレンゴムに大別され、非硫黄変性のものは、分子量調整剤の種類によって、更に、メルカプタン変性クロロプレンゴムとキサントゲン変性クロロプレンゴムとに分類される。硫黄変性クロロプレンゴムは、クロロプレンを主成分とする原料単量体と硫黄を共重合し、得られた共重合体をチウラムジスルフィドで可塑化して、所定のムーニー粘度に調整したものである。 On the other hand, chloroprene rubber is roughly classified into sulfur-modified chloroprene rubber and non-sulfur-modified chloroprene rubber. Non-sulfur-modified rubber is further classified into mercaptan-modified chloroprene rubber and xanthogen-modified chloroprene rubber according to the type of molecular weight modifier. The The sulfur-modified chloroprene rubber is obtained by copolymerizing a raw material monomer containing chloroprene as a main component and sulfur, and plasticizing the obtained copolymer with thiuram disulfide so as to have a predetermined Mooney viscosity.
一方、メルカプタン変性クロロプレンゴムは、分子量調整剤に、n−ドデシルメルカプタン、tert−ドデシルメルカプタン及びオクチルメルカプタンなどのアルキルメルカプタン類を使用することにより得られる。また、キサントゲン変性クロロプレンゴムは、分子量調整剤に、アルキルキサントゲン化合物を使用することにより得られる。そして、本実施形態のゴム組成物に配合されるクロロプレン系ゴムは、前述した各種クロロプレン系ゴムのいずれでもよいが、特にメルカプタン変性クロロプレンゴムやキサントゲン変性クロロプレンゴムが好適である。 On the other hand, mercaptan-modified chloroprene rubber is obtained by using alkyl mercaptans such as n-dodecyl mercaptan, tert-dodecyl mercaptan and octyl mercaptan as molecular weight modifiers. The xanthogen-modified chloroprene rubber can be obtained by using an alkyl xanthogen compound as a molecular weight regulator. The chloroprene rubber compounded in the rubber composition of the present embodiment may be any of the various chloroprene rubbers described above, but mercaptan-modified chloroprene rubber and xanthogen-modified chloroprene rubber are particularly suitable.
更に、クロロプレンゴムは、その結晶化速度に基づいて、例えば、結晶化速度が遅いタイプ、結晶化速度が中庸であるタイプ及び結晶化速度が速いタイプなどに分類することもできる。そして、本実施形態のゴム組成物は、前述した各タイプのクロロプレンゴムのいずれを用いてもよく、用途などに応じて適宜選択して使用することができる。 Furthermore, chloroprene rubber can be classified into, for example, a type having a low crystallization rate, a type having a moderate crystallization rate, and a type having a high crystallization rate based on the crystallization rate. The rubber composition of the present embodiment may use any of the above-described types of chloroprene rubber, and can be appropriately selected and used depending on the application.
クロロプレンゴムを製造する方法は、特に限定するものではないが、原料単量体を、乳化剤、重合開始剤及び分子量調整剤などの存在下で、一般に用いられる乳化重合法により重合させればよい。その際、乳化剤には、例えば炭素数が6〜22の飽和又は不飽和の脂肪族のアルカリ金属塩、ロジン酸又は不均化ロジン酸のアルカリ金属塩及びβ−ナフタレンスルホン酸のホルマリン縮合物のアルカリ金属塩など、一般にクロロプレンの乳化重合に使用される乳化剤を用いることができる。 Although the method for producing chloroprene rubber is not particularly limited, the raw material monomer may be polymerized by a commonly used emulsion polymerization method in the presence of an emulsifier, a polymerization initiator, a molecular weight modifier and the like. In this case, the emulsifier includes, for example, a saturated or unsaturated aliphatic alkali metal salt having 6 to 22 carbon atoms, an alkali metal salt of rosin acid or disproportionated rosin acid, and a formalin condensate of β-naphthalenesulfonic acid. An emulsifier generally used for emulsion polymerization of chloroprene, such as an alkali metal salt, can be used.
また、重合開始剤は、例えば過硫酸カリウム、過硫酸アンモニウム、過硫酸ナトリウム、過酸化水素及びtert−ブチルハイドロパーオキサイドなどの有機過酸化物類のように、一般にクロロプレンの乳化重合に使用される公知の重合開始剤を用いることができる。 Polymerization initiators are generally used for emulsion polymerization of chloroprene, such as organic peroxides such as potassium persulfate, ammonium persulfate, sodium persulfate, hydrogen peroxide and tert-butyl hydroperoxide. The polymerization initiator can be used.
なお、乳化重合する際の重合温度は、特に限定されるものではないが、生産性及び重合安定性の観点から、0〜50℃であることが好ましく、20〜50℃であることがより好ましい。また、単量体の最終転化率も、特に限定されるものはないが、生産性の観点から、60〜90%の範囲とすることが好ましい。 In addition, the polymerization temperature at the time of emulsion polymerization is not particularly limited, but is preferably 0 to 50 ° C., more preferably 20 to 50 ° C. from the viewpoint of productivity and polymerization stability. . Further, the final conversion rate of the monomer is not particularly limited, but is preferably in the range of 60 to 90% from the viewpoint of productivity.
そして、最終転化率が所定の範囲に達した時点で、重合液に重合禁止剤を少量添加して重合反応を停止させるが、その際、重合禁止剤としては、例えば、チオジフェニルアミン、4−tert−ブチルカテコール及び2,2−メチレンビス−4−メチル−6−tert−ブチルフェノールなど、通常用いられるものを用いることができる。また、重合反応後は、例えば、スチームストリッピング法などによって未反応の単量体を除去した後、ラテックスのpHを調整し、常法の凍結凝固、水洗及び熱風乾燥などの方法により、重合体を単離することができる。 When the final conversion rate reaches a predetermined range, a small amount of a polymerization inhibitor is added to the polymerization solution to stop the polymerization reaction. In this case, examples of the polymerization inhibitor include thiodiphenylamine, 4-tert Commonly used materials such as -butylcatechol and 2,2-methylenebis-4-methyl-6-tert-butylphenol can be used. Further, after the polymerization reaction, for example, after removing the unreacted monomer by a steam stripping method or the like, the pH of the latex is adjusted, and the polymer is obtained by a conventional method such as freeze coagulation, washing with water and drying with hot air. Can be isolated.
[リン酸系化合物:ゴム成分100質量部に対して0.5〜15.0質量部]
リン酸系化合物は、可塑剤や老化防止剤としての効果があり、後述する加硫物や成形加硫物の機械的強度を向上させ、高温圧縮永久歪みを改善させる。しかしながら、リン酸系化合物の添加量が、ゴム成分100質量部あたり0.5質量部未満の場合、高温圧縮永久歪みを改善させるのに十分な効果が得られない。一方、リン酸系化合物の添加量が、ゴム成分100質量部あたり15.0質量部を超えると、ゴムの硬度が低くなり、高温圧縮永久歪みが大きくなり、機械的強度が低下する。よって、リン酸系化合物の添加量は、ゴム成分100質量部あたり、0.5〜15.0質量部とする。特に、後述する加硫物や成形加硫物の機械的強度を更に向上させ、高温圧縮永久歪みを更に改善させるためには、ゴム成分100質量部あたり、0.5〜12.0質量部であるのが好ましく、1.0〜10.0質量部であるのがより好ましい。
[Phosphoric acid compound: 0.5 to 15.0 parts by mass with respect to 100 parts by mass of the rubber component]
The phosphoric acid compound has an effect as a plasticizer and an anti-aging agent, and improves the mechanical strength of a vulcanized product and a molded vulcanized product, which will be described later, and improves high temperature compression set. However, when the addition amount of the phosphoric acid compound is less than 0.5 parts by mass per 100 parts by mass of the rubber component, an effect sufficient to improve the high temperature compression set cannot be obtained. On the other hand, when the addition amount of the phosphoric acid compound exceeds 15.0 parts by mass per 100 parts by mass of the rubber component, the hardness of the rubber decreases, the high temperature compression set increases, and the mechanical strength decreases. Therefore, the addition amount of a phosphoric acid type compound shall be 0.5-15.0 mass parts per 100 mass parts of rubber components. In particular, in order to further improve the mechanical strength of the vulcanizate and molded vulcanizate described below and further improve the high temperature compression set, 0.5 to 12.0 parts by mass per 100 parts by mass of the rubber component It is preferable that it is 1.0 to 10.0 parts by mass.
ここで、リン酸系化合物としては、トリメチルホスフェート、トリエチルホスフェート、トリブチルホスフェート、トリス(2−エチルヘキシル)ホスフェート、トリフェニルホスフェート、トリクレジルホスフェート、トリキシレニルホスフェート、クレジルジフェニルホスフェート、2−エチルヘキシルジフェニルホスフェート、トリス(ノニルフェニル)ホスファイトなどが挙げられる。なお、これらは2種類以上併用することもできる。 Here, as the phosphoric acid compound, trimethyl phosphate, triethyl phosphate, tributyl phosphate, tris (2-ethylhexyl) phosphate, triphenyl phosphate, tricresyl phosphate, trixylenyl phosphate, cresyl diphenyl phosphate, 2-ethylhexyl diphenyl Examples include phosphate and tris (nonylphenyl) phosphite.

[ベンズイミダゾール系化合物:ゴム成分100質量部に対して0.05〜3.0質量部]
ベンズイミダゾール系化合物は、加硫促進剤としての効果があり、クロロプレン系ゴムの加硫速度を調節して、成型時における加工安定性を向上させる。しかしながら、後述するN−シクロヘキシルチオフタルイミドを用いない場合に、ベンズイミダゾール系化合物の添加量が、ゴム成分100質量部あたり0.05質量部未満の場合には、加工安定性を向上させるのに十分な効果が得られない。一方、ベンズイミダゾール系化合物の添加量が、ゴム成分100質量部あたり3.0質量部を超えると、加硫速度が速くなり、加工安定性等が低下する。ここで、加工安定性とは、スコーチタイムにより評価される。加工安定性は、不良発生率に大きく影響し、例えばスコーチタイムが短いと、高温での成形中に未加硫配合物が加硫されて成形不良が発生する頻度が高くなる。よって、ベンズイミダゾール系化合物の添加量は、ゴム成分100質量部あたり、0.05〜3.0質量部とする。特に、成型時における加工安定性を更に向上させるためには、ゴム成分100質量部あたり、0.1〜2.0質量部であるのが好ましく、特に0.1〜1.0質量部であるのがより好ましい。
[Benzimidazole compound: 0.05 to 3.0 parts by mass with respect to 100 parts by mass of the rubber component]
The benzimidazole compound has an effect as a vulcanization accelerator, and adjusts the vulcanization speed of the chloroprene rubber to improve the processing stability at the time of molding. However, when N-cyclohexylthiophthalimide, which will be described later, is not used, if the amount of benzimidazole compound added is less than 0.05 parts by mass per 100 parts by mass of the rubber component, it is sufficient to improve the processing stability. The effect is not obtained. On the other hand, when the addition amount of the benzimidazole compound exceeds 3.0 parts by mass per 100 parts by mass of the rubber component, the vulcanization rate is increased and the processing stability and the like are lowered. Here, the processing stability is evaluated by the scorch time. The processing stability greatly affects the defect occurrence rate. For example, if the scorch time is short, the frequency of occurrence of molding defects increases due to vulcanization of the unvulcanized compound during molding at high temperature. Therefore, the addition amount of the benzimidazole compound is 0.05 to 3.0 parts by mass per 100 parts by mass of the rubber component. In particular, in order to further improve the processing stability at the time of molding, it is preferably 0.1 to 2.0 parts by mass, particularly 0.1 to 1.0 part by mass per 100 parts by mass of the rubber component. Is more preferable.

N−シクロヘキシルチオフタルイミドは、スコーチ防止剤としての効果があり、クロロプレン系ゴムの加硫速度を調節して、成型時における加工安定性を向上させる。しかしながら、前記ベンズイミダゾール系化合物を用いない場合に、N−シクロヘキシルチオフタルイミドの添加量が、ゴム成分100質量部あたり0.05質量部未満の場合には、加工安定性を向上させるのに十分な効果が得られない。一方、N−シクロヘキシルチオフタルイミドの添加量が、ゴム成分100質量部あたり3.0質量部を超えると、加硫速度が遅くなりすぎて架橋密度が低下し、機械的強度や高温圧縮永久歪みが低下する。よって、N−シクロヘキシルチオフタルイミドの添加量は、ゴム成分100質量部あたり、0.05〜3.0質量部とする。特に、成型時における加工安定性を更に向上させるためには、ゴム成分100質量部あたり、0.1〜2.0質量部であるのが好ましく、特に0.1〜1.0質量部であるのがより好ましい。
[N-cyclohexylthiophthalimide: 0.05 to 3.0 parts by mass with respect to 100 parts by mass of the rubber component]
N-cyclohexylthiophthalimide has an effect as a scorch inhibitor and adjusts the vulcanization rate of the chloroprene rubber to improve the processing stability during molding. However, when the benzimidazole compound is not used and the amount of N-cyclohexylthiophthalimide added is less than 0.05 parts by mass per 100 parts by mass of the rubber component, it is sufficient to improve the processing stability. The effect is not obtained. On the other hand, when the addition amount of N-cyclohexylthiophthalimide exceeds 3.0 parts by mass per 100 parts by mass of the rubber component, the vulcanization rate becomes too low and the crosslinking density decreases, resulting in mechanical strength and high temperature compression set. descend. Therefore, the addition amount of N-cyclohexylthiophthalimide is 0.05 to 3.0 parts by mass per 100 parts by mass of the rubber component. In particular, in order to further improve the processing stability at the time of molding, it is preferably 0.1 to 2.0 parts by mass, particularly 0.1 to 1.0 part by mass per 100 parts by mass of the rubber component. Is more preferable.

なお、本実施形態のゴム組成物は、通常のゴム組成物と同様の方法で製造することができる。具体的には、クロロプレン系ゴム、リン酸系化合物、ベンズイミダゾール系化合物、N−シクロヘキシルチオフタルイミド及びその他の成分を、ニーダー、バンバリー又はロールなどの混練り機によって、加硫温度以下の温度で混練することにより得られる。 In addition, the rubber composition of this embodiment can be manufactured by the same method as a normal rubber composition. Specifically, chloroprene rubber, phosphoric acid compound, benzimidazole compound, N-cyclohexylthiophthalimide and other components are kneaded at a temperature below the vulcanization temperature by a kneader such as a kneader, Banbury or roll. Can be obtained.
以上詳述したように、本実施形態のゴム組成物は、ゴム成分としてクロロプレン系ゴムを用い、特定量のリン酸系化合物と、ベンズイミダゾール系化合物及びN−シクロヘキシルチオフタルイミドの少なくとも一方を特定量配合しているため、機械的強度や加工安定性を低下させることなく、高温圧縮永久歪みなどを向上させることができる。これにより、機械的強度や加工安定性、高温圧縮永久歪みに優れた加硫物が得られるゴム組成物を実現することができる。 As described above in detail, the rubber composition of the present embodiment uses chloroprene rubber as a rubber component, and a specific amount of a phosphoric acid compound, a specific amount of at least one of a benzimidazole compound and N-cyclohexylthiophthalimide. Since it mix | blends, high temperature compression set etc. can be improved, without reducing mechanical strength and process stability. Thereby, the rubber composition from which the vulcanizate excellent in mechanical strength, processing stability, and high-temperature compression set can be obtained can be realized.
<加硫物>(第2の実施形態)
本実施形態の加硫物は、前述した第1の実施形態のゴム組成物を、加硫したものである。その際、ゴム組成物の加硫方法は、特に限定されるものではなく、例えば、プレス加硫、インジェクション加硫、直接釜加硫、間接釜加硫、直接蒸気連続加硫、常圧連続加硫又は連続加硫プレスなどの加硫方法により、加硫すればよい。
<Vulcanized product> (Second embodiment)
The vulcanized product of the present embodiment is obtained by vulcanizing the rubber composition of the first embodiment described above. In that case, the vulcanization method of the rubber composition is not particularly limited, and for example, press vulcanization, injection vulcanization, direct kettle vulcanization, indirect kettle vulcanization, direct steam continuous vulcanization, normal pressure continuous vulcanization. Vulcanization may be performed by a vulcanization method such as vulcanization or continuous vulcanization press.
また、加硫温度及び加硫時間などの加硫条件も、特に限定されるものではなく、適宜設定することができるが、生産性及び加工安定性の観点から、加硫温度は130〜200℃とすることが好ましく、140〜190℃とすることがより好ましい。ここで、「加工安定性」とは、スコーチタイムにより評価される加工特性であり、不良発生率に大きく影響する。具体的には、スコーチタイムが短いと、高温での成形中に未加硫ゴム成分が加硫されて成形不良が発生する頻度が高くなる。 Further, vulcanization conditions such as vulcanization temperature and vulcanization time are not particularly limited and can be appropriately set. From the viewpoint of productivity and processing stability, the vulcanization temperature is 130 to 200 ° C. It is preferable to set it as 140 to 190 degreeC. Here, “machining stability” is a machining characteristic evaluated by the scorch time and greatly affects the defect occurrence rate. Specifically, when the scorch time is short, the frequency of occurrence of defective molding is increased because the unvulcanized rubber component is vulcanized during molding at a high temperature.
本実施形態の加硫物は、前述した第1の実施形態のゴム組成物を使用しているため、高温圧縮永久歪みなどが良好で、機械的強度や加工安定性にも優れる。 Since the vulcanized product of the present embodiment uses the rubber composition of the first embodiment described above, it has good high temperature compression set and excellent mechanical strength and processing stability.
<成形加硫物>(第3の実施形態)
本実施形態の成形加硫物は、前述した第1の実施形態のゴム組成物を、目的に応じた形状に成形加工して、成形時又は成形後に加硫して得たものである。その成形方法は、特に限定されるものではないが、プレス成形、射出成形及び押出成形などを適用することができる。そして、例えば、成形体が伝動ベルト、空気バネ、シール、パッキン、防振材、ホースなどである場合は、プレス成形や射出成形、押出成形により形成することができる。
<Molded vulcanizate> (Third embodiment)
The molded vulcanized product of the present embodiment is obtained by molding the rubber composition of the first embodiment described above into a shape suitable for the purpose and vulcanizing it during or after molding. The molding method is not particularly limited, and press molding, injection molding, extrusion molding, and the like can be applied. For example, when the molded body is a transmission belt, an air spring, a seal, packing, a vibration isolating material, a hose or the like, it can be formed by press molding, injection molding, or extrusion molding.
本実施形態の成形加硫物は、前述した第1の実施形態のゴム組成物を使用しているため、高温圧縮永久歪みなどが良好で、機械的強度や加工安定性にも優れる。 Since the molded vulcanizate of the present embodiment uses the rubber composition of the first embodiment described above, it has good high temperature compression set and excellent mechanical strength and processing stability.

<考察>
前記表1に示すように、リン酸系化合物を含有しない比較例1及びリン酸系化合物以外の可塑剤である脂肪族二塩基酸エステルを含有した比較例9は、高温圧縮永久歪みが劣っていた。一方、リン酸系化合物を含有していても、その添加量が0.5質量部未満である比較例3は、高温圧縮永久歪みが劣っていた。また、リン酸系化合物の添加量が15.0質量部を超えている比較例4は、ゴムの硬度が低くなり、高温圧縮永久歪みや機械的強度(引張り強度(TB))が劣っていた。
<Discussion>
As shown in Table 1, Comparative Example 1 containing no phosphoric acid compound and Comparative Example 9 containing an aliphatic dibasic acid ester which is a plasticizer other than the phosphoric acid compound have poor high temperature compression set. It was. On the other hand, even if the phosphoric acid compound was contained, Comparative Example 3 in which the addition amount was less than 0.5 parts by mass was inferior in high temperature compression set. Further, in Comparative Example 4 in which the addition amount of the phosphoric acid compound exceeds 15.0 parts by mass, the hardness of the rubber is low, and the high temperature compression set and mechanical strength (tensile strength (TB)) are inferior. .
また、ベンズイミダゾール系化合物及びN−シクロヘキシルチオフタルイミドのいずれも含有しない比較例2は、加工安定性(スコーチタイム)が劣っていた。一方、ベンズイミダゾール系化合物を含有していても、その添加量がゴム成分100質量部あたり0.05質量部未満である比較例5や、N−シクロヘキシルチオフタルイミドを含有していても、その添加量がゴム成分100質量部あたり0.05質量部未満である比較例6は、加工安定性(スコーチタイム)が劣っていた。また、他の加硫速度調整剤であるチウラム系化合物を含有する比較例10は、高温圧縮永久歪みが劣っていた。 Moreover, the comparative example 2 which contains neither a benzimidazole type compound nor N-cyclohexylthiophthalimide was inferior in processing stability (scorch time). On the other hand, even if it contains a benzimidazole compound, the addition amount is less than 0.05 parts by mass per 100 parts by mass of the rubber component, or even if it contains N-cyclohexylthiophthalimide. The comparative example 6 whose quantity is less than 0.05 mass part per 100 mass parts of rubber components was inferior in processing stability (scorch time). Moreover, the comparative example 10 containing the thiuram-type compound which is another vulcanization rate regulator was inferior in the high temperature compression set.
また、ベンズイミダゾール系化合物の添加量がゴム成分100質量部あたり3.0質量部を超える比較例7は、加硫速度が速くなりすぎて、高温圧縮永久歪みや加工安定性(スコーチタイム)が劣っており、N−シクロヘキシルチオフタルイミドの添加量がゴム成分100質量部あたり3.0質量部を超える比較例8は、加硫速度が遅くなりすぎて架橋密度が低下し、高温圧縮永久歪みや機械的強度(引張り強度(TB))が劣っていた。 In Comparative Example 7 in which the amount of benzimidazole compound added exceeds 3.0 parts by mass per 100 parts by mass of the rubber component, the vulcanization rate becomes too high, and the high temperature compression set and processing stability (scorch time) are high. In Comparative Example 8 in which the amount of N-cyclohexylthiophthalimide added exceeds 3.0 parts by mass per 100 parts by mass of the rubber component, the vulcanization rate becomes too slow and the crosslink density decreases, and high temperature compression set or Mechanical strength (tensile strength (TB)) was inferior.
これに対して、クロロプレン系ゴム100質量部あたり、リン酸系化合物を0.5〜15.0質量部、ベンズイミダゾール系化合物及びN−シクロヘキシルチオフタルイミドの少なくとも一方を0.05〜3.0質量部配合した、実施例1〜13では、機械的強度や加工安定性を低下させることなく、高温圧縮永久歪みに優れたゴム組成物を得られることが確認された。 On the other hand, per 100 parts by mass of chloroprene rubber, 0.5 to 15.0 parts by mass of the phosphoric acid compound, and 0.05 to 3.0 parts by mass of at least one of the benzimidazole compound and N-cyclohexylthiophthalimide. In Examples 1 to 13 which were partially blended, it was confirmed that a rubber composition excellent in high temperature compression set could be obtained without lowering mechanical strength and processing stability.
実施例の中で比較すると、加硫速度調整剤として、ベンズイミダゾール系化合物又はN−シクロヘキシルチオフタルイミドのどちらか一方を用いた実施例1又は実施例2に比べて、ベンズイミダゾール系化合物及びN−シクロヘキシルチオフタルイミドを併用した実施例3及び実施例13の方が、加工安定性(スコーチタイム)が優れていた。 When compared in the examples, as compared with Example 1 or Example 2 using either a benzimidazole compound or N-cyclohexylthiophthalimide as a vulcanization rate modifier, the benzimidazole compound and N- Example 3 and Example 13 in which cyclohexylthiophthalimide was used in combination were superior in processing stability (scorch time).
