Abstract
(EN)
[Problem] To provide the following: silicone resin-coated silicone elastomer particles which can be easily produced on an industrial scale, exhibit excellent oil absorption properties and dispersibility in a curable organic resin such as an epoxy resin, and exhibit excellent handling workability due to undergoing less secondary aggregation than conventional silicone elastomer particles; and applications containing the particles, such as organic resin additives, organic resins, paint compositions, coating agent compositions and cosmetic material compositions. [Solution] Provided are: silicone resin-coated silicone elastomer particles having a structure in which some or all of the surface of the particles is coated with a silicone resin comprising two types of siloxane unit selected from among D units represented by R2SiO2/2, T units represented by RSiO3/2 and Q units represented by SiO4/2, and at least two silicon atoms in a silicone elastomer particle are crosslinked by a silalkylene group having 2-20 carbon atoms; and uses thereof.

Le problème décrit par la présente invention est de fournir : des particules d'élastomère de silicone revêtues de résine de silicone qui peuvent être facilement produites à l'échelle industrielle, qui présentent d'excellentes propriétés d'absorption de l'huile et une très bonne dispersibilité dans une résine organique durcissable telle qu'une résine époxy, ainsi qu'une excellente aptitude à la manipulation et au façonnage en raison d'une agrégation secondaire inférieure à celle des particules d'élastomère de silicone classiques ; et des formulations contenant les particules, telles que des additifs pour résine organique, des résines organiques, des compositions de peinture, des compositions d'agent de revêtement et des compositions de substance cosmétique. La solution selon l'invention consiste en des particules d'élastomère de silicone revêtues de résine de silicone présentant une structure dans laquelle une partie ou la totalité de la surface des particules est revêtue d'une résine de silicone comprenant deux types de motifs siloxane sélectionnés parmi des motifs D représentés par R2SiO2/2, des motifs T représentés par RSiO3/2 et des motifs Q représentés par SiO4/2, et au moins deux atomes de silicium dans une particule d'élastomère de silicone sont réticulés par un groupe silalkylène comportant 2 à 20 atomes de carbone ; et leurs utilisations.

[課題]工業的スケールで容易に生産することができ、エポキシ樹脂等の硬化性有機樹脂への分散性および吸油性に優れ、かつ、従来のシリコーンエラストマー粒子に比べて二次凝集性が低いため取扱作業性に優れるシリコーン樹脂被覆シリコーンエラストマー粒子および、当該粒子を含有する有機樹脂添加剤、有機樹脂、塗料組成物またはコーティング剤組成物、および化粧料組成物等の用途を提供する。 [解決手段]その表面の一部又は全部がRSiO2/2で表されるD単位、RSiO3/2で表されるT単位およびSiO4/2で表されるQ単位から選ばれる2種類のシロキサン単位からなるシリコーン樹脂により被覆され、シリコーンエラストマー粒子内の少なくとも二つのケイ素原子が炭素数2~20のシルアルキレン基により架橋された構造を有する、シリコーン樹脂被覆シリコーンエラストマー粒子、およびその使用。
