Abstract

The invention relates to an emulsion used for herbal essence health coating, and particularly relates to a herbal essential oil emulsion which is covered by utilization of core-shell technology and used for coating release of herbal materials, and a preparation method of the emulsion. Raw materials of the emulsion comprise a core-part raw material and a shell-part raw material. The weight ratio of the core-part raw material to the shell-part raw material is 1:0.2-0.4. The emulsion has an obvious core-shell structure and good controlled-release function, and is fine in particle diameter, uniform in particle diameter distribution and good in gas permeability, and is stable,. Coatings of the herbal essence health coating prepared by the emulsion are excellent in comprehensive performances and good in gas permeability, and are water-proof, antiseptic, and capable of removing harmful gas effectively, inhibiting growth of various mycetes and releasing anions lastingly.

Description

technical field [0001] The invention relates to an emulsion for herbal essence healthy paint, in particular to a core-shell technology-coated herbal essential oil emulsion used for paint to release herbal substances and a preparation method thereof. Background technique [0002] With the development of "composite technology" in material science, scientists proposed a new concept of "particle design" in the 1980s. That is to compound from the particle level, rather than macroscopic mechanical mixing, so scientists proposed a new concept of "core-shell polymer emulsion". The so-called core-shell, as the name implies, refers to the structure in which the polymer A is the core and the latex particles of the outer layer of the polymer B are the shell. Polymerization makes the inside and outside of the particles enriched with different components, and through different combinations of core and shell, a series of latex particles of different shapes can be obtained, which can endow...
