Definitions
- the present invention relates to a rubber composition for bonding, and more particularly, to a rubber composition for bonding having improved breaking characteristics by blending a predetermined amount of a metal acetyl acetate toner having a defined particle size.
- an object of the present invention is to improve the breaking characteristics of an adhesive rubber composition containing a metal acetyl acetate such as a cobalt acetonate.
- the rubber component 1 0 0 part by weight and an average particle diameter of 5 0 mu m
- an adhesive rubber composition comprising 0.1 to 3 parts by weight of the following metal acetyl acetate toner.
- a rubber component and metal acetyl acetate having an average particle size of 50 ⁇ m or less are mixed at a maximum temperature of 140 ° C. or less during mixing.
- the present invention provides an adhesive rubber composition obtained by the above method.
- the particle size of the metal acetyl acetate used in the rubber composition for bonding is set to a certain value or less, and preferably the mixing temperature is further set to a certain temperature or less, whereby the breaking of the bonding rubber composition is broken. It has been found that the properties are significantly improved.
- Examples of the metal acetyl acetate to be used in the adhesive rubber composition of the present invention include cobalt (II) acetyl acetate, cobalt (III) acetyl acetate, nickel (II) acetyl acetate and zirconium ( IV) Acetyl acetate, zinc (II) acetonate, copper (II) acetonate, iron (II) acetonate, iron (III) acetonate, chromium (III) acetonate, manganese (II) acetyl acetate and molybdenum (II) acetonate.
- cobalt (II) acetyl acetate and Z or cobalt (III) acetonate are particularly preferred.
- the average particle size is 50 Xm or less
- 0.1 to 3 parts by weight preferably 0.5 to 2 parts by weight of 100 to 100 parts by weight of the rubber component, preferably 10 to 20 m of metal acetyl acetate.
- the fracture characteristics can be improved while maintaining good adhesion. If the particle size of the metal acetyl acetate exceeds 50 zm, the resulting rubber composition undesirably deteriorates in adhesiveness and breaking strength. When the amount is less than 0.1 part by weight, the intended effect is not exhibited. On the other hand, when the amount exceeds 3 parts by weight, the breaking strength is undesirably reduced.
- the maximum temperature at the time of mixing the metal acetyl acetate toner having the predetermined particle size and the predetermined compounding amount into the rubber composition is preferably 140 ° C. or less, more preferably It is more preferable to control the temperature in the range of 90 to 120 ° C. By mixing in this temperature range, the dispersion of the metal acetyl acetate in the rubber becomes good, and the decrease in the breaking strength can be further suppressed.
- the rubber component used in the bonding rubber composition of the present invention any rubber that can be used as a tire rubber, for example, a gen-based rubber alone, or any mixture thereof can be used. .
- NR natural rubbers
- BR butadiene rubbers
- SBR styrene-butadiene copolymer rubbers
- IR polyisoprene rubbers
- IIR butyl rubbers
- Acrylonitrile-butanol-butadiene copolymer rubber rubber mouth rubber
- ethylene-propylene-copolymer rubber styrene-isoprene copolymer rubber
- styrene-butadiene copolymer rubber etc.
- blends using a large amount of natural rubber are desirable from the viewpoint of adhesiveness and rubber strength.
- Sulfur generally used in the adhesive rubber composition of the present invention is preferably 3 to 10 parts by weight, more preferably 100 parts by weight of the rubber component. It is blended in an amount of 5 to 8 parts by weight. If the amount is too small, the adhesiveness may be deteriorated. If the amount is too large, the physical properties of the obtained rubber composition may be reduced, and the adhesiveness after aging may be deteriorated.
- the adhesive rubber composition of the present invention further includes other vulcanizing or cross-linking agents, vulcanizing or cross-linking accelerators, reinforcing fillers such as carbon black and silica, various oils, anti-aging agents, fillers, and softening agents.
- Various additives and additives commonly used for tires, such as additives, plasticizers, etc. can be added, and the amounts of these additives and additives are not limited to the general range as long as they are not contrary to the object of the present invention. Amount. Of these, it is desirable to use 45 to 65 phr (parts per 100 parts by weight of rubber) of carbon black of N2334 or N330 grade. It is particularly preferable to add 3 to llphr, 1 phr or less of stearic acid and 1 phr or less of a vulcanization accelerator.
- Cobalt ( ⁇ ) acetonacetate manufactured by Nippon Kagaku Sangyo Cobalt (m) acetonate of each particle size is obtained by crushing a commercially available cobalt ( ⁇ ) acetilacetonate product and sieving it. (Use the one with a diameter)
- a rubber composition was obtained by kneading the respective components shown in Table 1 below at the respective predetermined mixing temperatures, and then this was press-vulcanized at 148 ° C for 45 minutes to obtain a rubber sheet having a thickness of 2 mm.
- a JIS No. 3 dumbbell-shaped test piece was punched out from the sheet, and the breaking strength was measured in accordance with JISK6251.
- the rubber composition for bonding by this invention is excellent in the physical property of breakage as rubber
