Abstract

The invention relates to chemical polymer materials, which in detail relates to high solid content nanometer microemulsion polymerization with core-shell structure. The granular size is 30-100 nanometer, solid content is 46- 49%, and core mixed monomer is 40-70% of that of total core-shell monomer. The core mixed monomer comprises alkyl acrylate, methacrylate and alkyl methacrylate esters orvinyl aromatic compounds, acrylate-hydroxy ester, alkyl acrylic acid. The shell mixed monomer comprises alkyl acrylate, methacrylate and alkyl methacrylate esters, acrylate-hydroxy ester, alkyl acrylic acid. The proportion of said components are as follows: alkyl acrylate 39-48%, methacrylate and alkyl methacrylate esters 20-53%, vinyl aromatic compounds 0-30%, acrylate-hydroxy ester 3- 4%, alkyl acrylic acid 3- 4%. The invention is characterized by high solid content of more than 45% and reduced viscosity.

Description

Technical field: [0001] The invention belongs to the field of chemical polymer materials, in particular to an acrylate microemulsion with a particle size of 30-100nm and a solid content greater than 45% and a preparation method thereof Background technique: [0002] Microemulsion was first proposed by Hoar and Schulman, it is a thermodynamically stable, optically transparent or translucent dispersion system, its particle size is less than 100nm, while the particle size of the microemulsion is 100-400nm, and the particle size of the ordinary emulsion is generally several Hundreds of nanometers to thousands of nanometers. The application of microemulsion technology to the synthesis and research of water-based polymers began in the early 1980s. As a kind of nanomaterial, nano-polymer particles obtained by microemulsion polymerization have excellent properties different from those under normal conditions, which quickly attracted people's attention. of great attention.
