Polymerizing process for preparing nano microcapsule by radiating emulsion

Abstract

A radiating polymerization process for preparing nano microcapsules includes such steps as proportioning core, monomer, emulsifier and water, mixing core with monomer, adding emulsifier and water, strong stirring for 15-45 min, high-energy ray radiating while aerating nitrogen gas for polymerizing reaction for 5-6 hr, filtering, and neutralizing to 5-7 of pH value with diluted ammonia solution.

Description

technical field

[0001] The invention relates to a method for preparing nanometer microcapsules by radiation emulsion polymerization, which relates to a method for preparing nanometer microcapsules by radiation emulsion polymerization. Background technique

[0002] Microcapsule technology is a technology that coats solid or liquid with film-forming materials to make them into tiny particles. The resulting tiny particles are called microcapsules. The particle size of microcapsules usually prepared is between 5 and 2000 μm, which is called micron microcapsules. Its larger particle size restricts the wider application of microencapsulation technology. With the development of science and technology, people use high technology to make the prepared microcapsules have a particle size between 1 and 1000 μm. Scientists define such microcapsules with a particle size in the nanometer range as nano-microcapsules. The current chemical emulsion polymerization method used to produce nano-...
