Description

ゴム組成物、塗料および接着剤Rubber compositions, paints and adhesives
 本発明は、ゴム組成物、塗料および接着剤に関する。 The present invention relates to rubber compositions, paints, and adhesives.
 タイヤの製造過程において、タイヤ本体に取り付けられる前の未加硫状態のトレッドは、その仕様等が表面にマーキングされている。作業者はそのマーキングを確認して、当該未加硫状態のトレッドをタイヤ本体に巻き付け、成形金型に入れた後、加熱して加硫反応によりトレッドをタイヤ本体と一体化してタイヤを製造する。 In the tire manufacturing process, the unvulcanized tread before being attached to the tire body has its specifications marked on its surface. The worker checks the markings, wraps the unvulcanized tread around the tire body, places it in a mold, heats it, and integrates the tread with the tire body through a vulcanization reaction to manufacture the tire. .
 上記マーキングには、例えばラテックスに顔料を添加した塗料が使用される。ラテックスはゴムが水又は水溶液に微粒子状に分散したエマルジョンであって、当該ラテックスを含有する塗料は、得られる塗膜がゴムの伸縮に追従できる柔軟性を備えた塗料である(特許文献1)。また、上記ラテックスはその柔軟性から接着剤としても使用される(特許文献2)。 For the above marking, for example, a paint made by adding pigment to latex is used. Latex is an emulsion in which rubber is dispersed in water or an aqueous solution in the form of fine particles, and paints containing this latex have the flexibility to allow the resulting coating film to follow the expansion and contraction of the rubber (Patent Document 1) . Furthermore, the latex is also used as an adhesive due to its flexibility (Patent Document 2).

(Example 1-15 and Comparative Example 1-4: Preparation and evaluation of rubber composition)
Distilled water was added to a commercially available latex liquid (98% by mass natural rubber dispersion in water) to prepare a 60% by mass natural rubber latex liquid. A rubber composition was prepared by adding the metal soap shown in Table 1 to the prepared latex liquid.
The drying performance of the prepared rubber composition was evaluated by the following method. The results are shown in Tables 1 and 2. Further, Table 3 shows the metal soaps used in the examples.
(乾燥性能試験)
 調製したゴム組成物をガラス基板上にWet膜厚152μmの塗膜を塗工した。ゴム組成物を塗工したガラス基板を温度30℃×湿度60%の保管庫に保存し、塗膜を指先で触って乾燥状態を確認した。指先に評価用塗料がつかなくなった時間を乾燥時間として評価した。この試験は合計3回行った。
(Drying performance test)
The prepared rubber composition was coated on a glass substrate to form a wet film with a wet film thickness of 152 μm. The glass substrate coated with the rubber composition was stored in a storage at a temperature of 30° C. and a humidity of 60%, and the dry state was checked by touching the coating film with a fingertip.
