聚氨酯混合微胶囊及其制备方法
摘要：
本发明涉及微胶囊制备领域，尤其涉及一种聚氨酯混合微胶囊及其制备方法。聚氨酯混合微胶囊包括聚氨酯包裹异氰酸酯微胶囊、聚氨酯包裹羟基化合物微胶囊以及助剂；所述聚氨酯包裹异氰酸酯微胶囊的壁层为聚氨酯，芯层为异氰酸酯；所述聚氨酯包裹羟基化合物微胶囊的壁层为聚氨酯，芯层为羟基化合物；所述助剂为聚氨酯催化剂。制备得到的聚氨酯混合微胶囊具有较好的氨纶相容性，耐热性以及抗渗透性。
摘要（英）：

The invention relates to the field of microcapsule preparation, and in particular relates to a polyurethane mixed microcapsule and a preparation method thereof. The polyurethane mixed microcapsule includes a polyurethane-coated isocyanate microcapsule, a polyurethane-coated hydroxyl compound microcapsule and an auxiliary agen; a wall layer of the polyurethane-coated isocyanate microcapsule is polyurethane, a core layer is isocyanate; a wall layer of the polyurethane-coated hydroxyl compound microcapsule is the polyurethane, a core layer is a hydroxyl compound; the auxiliary agent is a polyurethane catalyst. The prepared polyurethane mixed microcapsule has good spandex compatibility, heat resistance and impermeability.
