Abstract

The invention relates to the technical field of microcapsules and particularly relates to microcapsule granules and a preparation method thereof. The microcapsule granule is prepared from a wall material and a core material, wherein the wall material is prepared from a first wall material and a second wall material; the first wall material and the second wall material are independently selected from a polyanionic electrolyte, a polycationic electrolyte and a polymer amphoteric electrolyte; the first wall material and the second wall material are different kinds of polyelectrolytes; the mass ratio of the first wall material to the second wall material is 10:(1-10); the microcapsule granules include nonspherical microcapsule granules with grooves in the surfaces. According to the microcapsule granules and the preparation method thereof provided by the invention, two different kinds of polyelectrolytes are mixed according to a specific ratio to obtain the wall material; the prepared microcapsule granules include 70%-85% of nonspherical microcapsule granules with grooves in the surfaces.

Description

technical field [0001] The invention relates to the technical field of microcapsules, in particular to a non-spherical microcapsule particle and a preparation method thereof. Background technique [0002] Microcapsule refers to a kind of micro container or micro package, in which the wrapped substance is called core material, and the part wrapped around the core material is called wall material. The core material can be solid, liquid and gaseous, and the wall material can be natural polymer materials, or new materials such as liposomes and microbial cell walls. Microcapsule technology has been widely used in food, medicine, chemical industry, agriculture, cosmetics and other industries. [0003] In recent years, the preparation technology of spherical microcapsule particles has become more and more mature. Chinese patent 201010219069.5 discloses a method for preparing spherical gelatin microspheres with smooth surfaces; Chinese patent 201310101134.8 discloses a magnetic fie...
