目的 探討金黃涂膜劑的制備方法。方法 采用正交試驗設計，以外觀性狀和成膜時間為指標，篩選金黃涂膜劑的最優(yōu)處方。結果 以鄰苯二甲酸二乙酯、聚乙烯醇（1788）、聚乙烯醇縮甲乙醛按比例1∶2∶5制得的制劑成膜性和穩(wěn)定性均較好。結論 優(yōu)選的金黃涂膜劑制劑設計合理，制備工藝簡便可行。

Objective To study the preparation method of Jinhuang Plastics. Methods Using appearance characteristics and film-forming time as indexes, to choose the best formula of Jinhuang Plastics by orthogonal test. Results The optimized formulation has the advantages of well filmed and long stability with diethyl phthalate-polyvinyl alcohol (1788)-polyvinylformal acetal (1∶2∶5). Conclusion The Jinhuang Plastics are reasonably designed and easily prepared.
