Calcium carbonate filler for resin, and resin composition containing said filler |
| abstract |
Provided is a calcium carbonate filler for resin, in particular, a filler that is useful in the field of optics in which reflectance and light resistance are required, said filler enabling the suppression of bubbles and the like by simplifying the degassing of volatile components such as water present on the calcium carbonate surface, even when a high concentration of the filler is blended into and kneaded with a resin having a high working temperature. In the number particle size distribution as measured by electron micrograph, the calcium carbonate filler for resin contains at most 30% of particles having a particle size of 0.26[mu]m or less, and satisfies formulas (a) Dms5/Dmv5<=3.0, (b) 1.0<=SW<=10.0(m2/g), and (c) Dma<=5.0(vol%). Dms5: 5% diameter ([mu]m) accumulated from the small particle side in volume particle size distribution measured by a laser diffraction particle size distribution measurement device; Dmv5: 5% diameter ([mu]m) accumulated from the small particle side in number particle size distribution of particle size measured by electron microscope; Sw: BET specific surface area (m2/g); Dma: content ratio (vol%) of particles having a particle size of at least 3[mu]m in volume particle size distribution measured by a laser diffraction particle size distribution measurement device. |
