Title:
SLOW-RELEASE MILDEW-PROOF CASEIN-BASED HOLLOW MICROSPHERE COATING MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2017/121369
Kind Code:
A1
Abstract:
A slow-release mildew-proof casein-based hollow microsphere coating material and a preparation method therefor. The casein is used as a base material, monomers, such as methyl methacrylate, butyl acrylate, methacrylic acid, are introduced, and a casein-based polymer emulsion having a special hollow structure is prepared by using a seed emulsion polymerization method and an alkali swelling method. In addition, by means of the special structure of the hollow microspheres, the interior of the hollow microspheres is coated with a mildew-proof agent, so that a slow-release mildew-proof effect on leather can be achieved by changing external release conditions. The material, when being applied in a leather finishing agent, has important significance on improvement of quality and grade of aniline leather and full grain leather products.
