- the mixture was mixed to make Polymer W3 ⁇ 4l. While mixing the fatty acid prepared in the comparison l with calcium chloride, 3-aminopropyltriethoxysilane (S-330, manufactured by Chisso Corp.) was added to the raw material ⁇ 7 r.d. 1. The mixture was exfoliated in an amount of 1 part, heated for 10 minutes, and then heated and dried at 100 ° C. for 60 minutes to prepare a partial resin having an organic acid layer and a silane coupling agent layer.
- Example 2 In the same manner as in Example 1, a synthetic rubber (SBR 1502) is blended with the above-mentioned material and a partially sulphide having a silane coupling agent layer in a manner to remove 10% of the rubber from 10% of the rubber. "created.
- we used wet silica (Nippon Silica Dish Nip Seal VN 3) with a BET specific surface area of 175 m 2 / g.
- the obtained unvulcanized rubber was subjected to an oscillating disk rheometer: t c (90) between mouth and mouth was calculated, and press-crosslinking was performed at this time to obtain a press vulcanized sheet.
- test items were measured in 23 using the shopper tensile strength ⁇ ⁇ ⁇ ⁇ according to the male specified in JIS K 6251.
- the number of bends was measured using a Ueshima Seisakusho's Demachia Flex until the flex at the time of flexure became 10 mm.
- the l-thickness used was 6.3 mm and the flexion was 300 times.
- the cut-off fiber is 5 5 7, the sword: ⁇ is 75 5.
- the value at 23 ° C. was measured using a Lupke fiber optic device. Try! The thickness of 1 was 12.5 mm and the diameter was 29 mm.
- the shape of the dumbbell was 1 and the marked line was 40 mm. Cut at tension Elongated 50% of the instantaneous elongation and worked in this female for 30 minutes. After 30 ⁇ 3 ⁇ 4i, external force was removed and the sample was left still for 30 minutes, and the residual elongation at this time was measured. As a result, the residual elongation with respect to the original length (40 mm) is expressed as a percentage.
- the roll calorie property was inferred from the ease of winding the polymer ffi ⁇ ti around the roll at the time of rubber weaving. ⁇ 3 ⁇ 4 ⁇ : The larger the roll, the harder it is. On the consultation side, the degree of winding of the polymer at the time of satisfaction was evaluated.
- Comparative Stitch 1 Polymer containing calcium carbonate, which does not have sufficient physical properties in terms of modulus, 3 ⁇ 4s, bow 1 was.
- the polymer iwti containing calcium carbonate having only the silica layer and the silane coupling agent layer shown in Comparative Example 4 had insufficient physical properties with respect to mechanical growth such as 7 elongation. In addition, the wrapping around the roll was poor and the roll workability was poor. As shown in Fig. 5, the polymer containing BETit surface crane M, silica layer and silane coupling agent layer containing only calcium has low strength such as penetration, bending resistance, and anti-seizure properties. Les r Enough physical properties Shame was good.
- the calcium in the present invention has at least one member selected from the group consisting of (i) a silica layer on the surface thereof, and (ii) a fat ester, a fat salt, a fat ester, a transester, or a jujutsu test confirmation ester. It has a functional organic layer, and further has a (source) silane cup link ⁇ I ”layer.
- the polymer containing calcium carbonate of the present invention exhibits high strength and high elongation as compared with the polymer containing white carbon, and also has excellent permanent elongation and roll processability. Also, since the drying of coal and calcium is suppressed, there are few difficult coarse particles.
- the modified calcium carbonate of the present invention having such excellent properties and the polymer containing the same can be usefully used for applications such as tires and tires.
