(ZH) 一种高紫外吸收的木质素/化学防晒剂微胶囊及制备方法
Abstract:
(EN) A method for preparing a high-ultraviolet absorption lignin/chemical sun-screening agent microcapsule using lignin as a wall material, comprising the steps of (1) dissolving 1-20 parts by weight of lignin in 100-200 parts by weight of an aqueous solution with a pH of 12, adjusting the pH of the solution to 7-10, and then removing insoluble substances by filtration to obtain a lignin solution; and (2) mixing 10-50 parts by weight of the lignin solution in step (1) with 1-10 parts by weight of a chemical sun-screening agent, and performing ultrasonic radiation under a power of 200-1500 W for 10 s to 25 min to obtain a lignin/chemical sun-screening agent microcapsule emulsion.
(FR) L'invention concerne un procédé de préparation d'une microcapsule à haute absorption du rayonnement ultraviolet constituée de lignine et d'un agent de protection solaire chimique, utilisant la lignine comme matériau de paroi, comprenant les étapes consistant à (1) dissoudre 1 à 20 parties en poids de lignine dans 100 à 200 parties en poids d'une solution aqueuse à pH 12, ajuster le pH de la solution pour atteindre un pH compris entre 7 et 10, puis éliminer les substances insolubles par filtration pour obtenir une solution de lignine; et (2) mélanger 10 à 50 parties en poids de la solution de lignine de l'étape (1) avec 1 à 10 parties en poids d'un agent de protection solaire chimique, et appliquer un rayonnement ultrasonique à une puissance comprise entre 200 et 1 500 W pendant 10 s à 25 min afin d'obtenir une émulsion de microcapsules constituées de lignine et d'un agent de protection solaire chimique.
(ZH) 一种应用木质素为壁材制备的高紫外吸收的木质素/化学防晒剂微胶囊的制备方法,包括以下步骤:(1)将1~20重量份木质素溶解于100~200重量份的pH为12的水溶液中,调节溶液pH至7~10后滤除去不溶物,得到木质素溶液;(2)将10~50重量份步骤(1)的木质素溶液与1~10重量份的化学防晒剂混合,在200~1500W的功率下超声辐射10s~25min,得到木质素/化学防晒剂微胶囊乳液。
