For example, when mold vulcanization was carried out at 160° C., which tended to increase the curing time, a vulcanization time of 12 minutes or more was required to achieve sufficient vulcanization. In addition, if the mold temperature, that is, the vulcanization temperature, is increased,
Although the vulcanization time can be shortened, scorch may be generated at the contact part of the mold when the rubber material is set, and if the molded product has an undercut, the molded product may tear (tear) when the mold is released.
There was a risk that something like this would occur.

混練した後のゴム材料について、下記方法により各試験
を行なった。The rubber materials of the respective Examples (Comparative Examples) having compositions in which vulcanization accelerators were combined as shown in Table 1 in the separately described basic formulation were kneaded, and then various tests were conducted using the following methods.
（１）加硫速度

する応力を連続的に測定するものである。(1) Vulcanization rate The vulcanization rate was determined under the following conditions using a JSR Curelastometer type III (manufactured by Imanaka Kijo Kogyo ■, sold by Nichirei Shoji ■). Note that the curelastometer continuously measures the stress generated by applying vibrational deformation of a constant amplitude to a sample that is being vulcanized or hardened at a constant temperature.

に達する時間をＴＬＯ（分）とした。Measurement conditions: amplitude angle ±3°, frequency 100 cps, 1
In the stress continuous curve obtained at 70℃, the time to reach 90% of the maximum stress is 790 (min), 10%
The time to reach this point was defined as TLO (minutes).
この場合、Ｔ９０に相当する時間がそのゴム試料の試験
温度における適正加硫時間、またＴｌ１Ｉに相当する時
間がスコーチ時間となる。In this case, the time corresponding to T90 is the proper vulcanization time at the test temperature of the rubber sample, and the time corresponding to Tl1I is the scorch time.
（２）常態物性

A test piece was obtained according to JISK6301, and the hardness (Hs), tensile strength (Ta),
) was sought.

ゾリン系（＃２２）とチウラム系（ＴＴ）との、又は、
イミダゾリン系（＃２２）とチアゾール系（ＤＭ）との
組合せではＴｇＯが長く、加硫時間の短縮が望めない（
比較例１・２）。From the test results shown in Table 1, it can be seen that: ■ between imidazoline type (#22) and thiuram type (TT)
The combination of imidazoline type (#22) and thiazole type (DM) has a long TgO, and shortening of the vulcanization time cannot be expected (
Comparative Examples 1 and 2).
■チオウレア系とチウラム系の組合せでは、Ｔ匍が短か
く、かつＴ１０が長くなり、加硫速度的に問題はないが
、ゴムの架橋密度が十分でなく（Ｈ５低下、ＥＢ大）、
加硫ゴム物性に問題を生じる（比較例３）。■The combination of thiourea and thiuram has a short T and long T10, and there is no problem in terms of vulcanization speed, but the crosslinking density of the rubber is insufficient (lower H5, larger EB),
Problems arise in the physical properties of the vulcanized rubber (Comparative Example 3).
■イミダゾリン系、チオウレア系、チウラム系の三成分
を組合せた場合は、Ｔ田が短かく、かっＴＬｏも比較的
長く、しかも加硫ゴム物性もほぼ良好であるが、伸び（
ＥＢ）が実施例に比して小さい（比較例４）。■When the three components of imidazoline type, thiourea type, and thiuram type are combined, the T field is short, the TLo is relatively long, and the physical properties of the vulcanized rubber are almost good, but the elongation (
EB) is smaller than that of the Example (Comparative Example 4).

In addition, the physical properties of the vulcanized rubber are also almost good, and in particular, the elongation (EB) is greater than that of Comparative Example 4. The elongation of the four-component combination type is greater than that of the three-component combination type (Examples 1 and 2).
