| description | 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 0.26μm 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 (μm) accumulated from the small particle side in volume particle size distribution measured by a laser diffraction particle size distribution measurement device; Dmv5: 5% diameter (μm) 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 3μm in volume particle size distribution measured by a laser diffraction particle size distribution measurement device.
L'invention concerne une matière de charge de carbonate de calcium pour résine, en particulier une matière de charge utilisable en optique et dont on exige une réflectance et une résistance à la lumière, cette charge permettant de supprimer les bulles ou similaires par un dégazage simplifié de composants volatils tels que l'eau présents à la surface du carbonate de calcium, même si de la charge à haute concentration est mélangée à une résine à température de travail élevée et pétrie avec celle-ci. Au niveau de la distribution granulométrique en termes de nombre mesurée par micrographe électronique, la matière de remplissage de carbonate de calcium pour résine contient au plus 30 % de particules ayant une taille de particules de 0,26μm ou moins et satisfait les formules (a) Dms5/Dmv5 ≤ 3,0, (b) 1,0 ≤ SW ≤ 10,0 (m2/g), et (c) Dma (vol %) ≤ 5,0.
