The invention relates to the technical field of biological medicines, and discloses a high-refractive-index
polymer microsphere, which is prepared from the following raw materials in parts by weight: 100 to 200 parts of aliphatic
conjugated diene monomers, 10 to 100 parts of
ethylene unsaturated
carboxylic acid monomers, 20 to 40 parts of
acrylonitrile monomers, 10 to 30 parts of medium-chain fatty
glyceride and 5 to 15 parts of aluminum compound
aqueous solution. According to the high-refractive-index
polymer microsphere and the preparation method thereof, the latex prepared by the method is more stable in structure, lower in production cost, higher in safety and stability in the production process, and capable of effectively inhibiting generation of cracks, various characteristics such as waterproofness,
chemical resistance and the like obtained by forming the rubber layer are sufficient, and the high-refractive-index
polymer microsphere can be used for preparing the high-refractive-index polymer microsphere. According to the present invention, the prepared latex has the advantages of high tensile strength, sufficient tensile strength of the obtained film molding body such as the dipping molding body, excellent hand feeling and excellent elongation, the controllable production cost can be ensured while the
adhesion strength of the latex is ensured, and the product has advantages of
high reflectivity and good application effect.
