一种含纳米SiO2的包衣剂及其制备方法
摘要：
本发明涉及包衣剂技术领域，具体涉及一种含纳米SiO2的包衣剂及其制备方法，该包衣剂由以下重量份的原料组成：50‑60%成膜剂、5‑10%增塑剂、2‑6%分散剂、10‑30%着色剂、15‑20%抗粘剂、2‑5%纳米SiO2。本发明利用纳米SiO2与处方中的成膜剂形成复合材料，增强了包衣剂的性能，增强了包衣剂的性能，改善包衣膜强度，提高屏蔽紫外防变色功能，有利于提高药品的贮存稳定性。本发明制得的包衣剂的抗紫外变色功能提高75%以上，薄膜衣强度提高30%以上。
摘要（英）：

The present invention relates to the technical field of coating agent, in particular to a coating agent containing nano-SiO2 and a preparation method thereof. The coating agent consists of raw materials in parts by weight as follows: 50-60% film-forming agent, 5-10% plasticizing agent, 2-6% dispersing agent, 10-30% coloring agent, 15-20% antisticking agent and 2-5% nano-SiO2. In the present invention, the nano-SiO2. and the film-forming agent in the formulation can form a composite, which can enhance the property of coating agent, improve the coating film strength, and enhance the UV-protection and anti-discoloration functions, so as to improve the storage stability of drugs. The UV-protection and anti-discoloration functions of the coating agent prepared herein can be improved by more than 75%, and their film strength can be improved by more than 30%.
