（！Ｉ！施例）
表−１に本発明の実施例及び比較例を示す。表中、ｘ印
は鉛との°反応により汚染が発生する組合わせ、Ｑ印は
汚染の発生しない組合わせを示す。(!I!Example) Table 1 shows examples and comparative examples of the present invention. In the table, the x mark indicates a combination in which contamination occurs due to reaction with lead, and the Q mark indicates a combination in which contamination does not occur.
また、評価方法は、各未加硫ゴムシート（１０Ｑｙｓｗ
ｔ角ｘ２ｔｔｔｍ厚）に鉛板（１００ＩＦＮ角×１１１
１＃ｌ厚）を貼り合わせた後、デンスにて１５０℃Ｘ３
０分加硫を行い、鉛板を取りはずし肉眼にて汚染の有無
を評価した。In addition, the evaluation method was as follows: each unvulcanized rubber sheet (10Qysw
T angle x 2tttm thickness) and lead plate (100 IFN angle x 111
After bonding 1#l thickness), heat at 150℃ x 3 in a dense
After vulcanization for 0 minutes, the lead plate was removed and the presence or absence of contamination was evaluated with the naked eye.
尚、この評価に用いた配合は、汚染の有無が容易に判定

。The formulation used for this evaluation was a white formulation [polymer (Table 1)] in order to easily determine the presence or absence of contamination.
100 parts, stearic acid 1 part, zinc white 5 parts, leg strength A'
50 parts, O/I/10 parts, vulcanization system (Table 1)].
表−１から明らかなように、チアゾール系促進剤を用い
た比較例においては、いずれも汚染が発生したのに対し
、実施例においての全く汚染が発生しなかった。この理
由は、チアゾール系促進剤の場合には、亜鉛（組成物中
に配合されている）とよりも鉛との反応の方が著しく速
いため、加硫副生咬物と己で硫化鉛が生成し汚染するの
に対し。As is clear from Table 1, staining occurred in all of the comparative examples using thiazole-based accelerators, whereas no staining occurred in the examples. The reason for this is that in the case of thiazole accelerators, the reaction with lead is significantly faster than with zinc (which is included in the composition), so lead sulfide is generated by the vulcanization by-products and by itself. whereas it generates and pollutes.
チウラム系及びジチオ酸塩系促進剤の場合には。In the case of thiuram and dithioate accelerators.
鉛とよりも亜鉛との反応が著しく速いため、硫化鉛の生
成がなく、汚染は全く問題とならないと考えられる。Since the reaction with zinc is much faster than with lead, no lead sulfide is produced and contamination is considered to be no problem.
