Polymer microsphere with high refractive index and preparation method thereof

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of biomedicine, in particular to a high refractive index polymer microsphere and a preparation method thereof. Background technique [0002] Synthetic latexes are used in coatings (e.g., latex paints) and glues because they cure through the agglomeration of polymer particles as the water evaporates and thus can form films without releasing potentially toxic organic compounds into the environment solvent. Other uses include cement additives, and hiding information on scratch cards. Latex (usually styrene-based latex) is also used in immunoassays. [0003] Due to the unique properties of latex, latex is now widely used in the field of biomedicine. However, the current latex microspheres are affected by formulation and process during preparation, resulting in poor latex microspheres with poor refractive index properties, and the preparation is also very inconvenient.
