Problems solved by technology

In the polymerization process of the micro-suspension method, the vinyl chloride monomer must first be dispersed into liquid droplets of about 0.1-2.0 μm and remain stable during polymerization. There must be special equipment in the production device to disperse the vinyl chloride monomer, and the process is relatively complicated. The latex particle size obtained by the ordinary emulsion method is below 0.2 μm, which cannot meet the requirements of the polyvinyl chloride paste resin latex particle size of 0.2-1.5 μm for glove materials

Abstract

The invention provides a method for producing polyvinyl chloride paste resin used for glove materials, which comprises (1) preparation of seeds in which the seeds with a particle size ranging from 0.4 to 0.6Mum and a weight solid content ranging from 25 percent to 40 percent are obtained and (2) preparation of the glove materials. The polyvinyl chloride paste resin used for glove materials which is prepared by adopting the method of the invention has a particle size ranging from 0.2 to 1.5Mum, the particle sizes are distributed uniformly and the invention can meet the requirements for production of the polyvinyl chloride paste resin used for glove materials.

Description

technical field [0001] The invention relates to a production method of polyvinyl chloride paste resin. Background technique [0002] At present, the polyvinyl chloride paste resin used for glove materials generally adopts the microsuspension method or the emulsion method. In the polymerization process of the micro-suspension method, the vinyl chloride monomer must first be dispersed into liquid droplets of about 0.1-2.0 μm and remain stable during polymerization. There must be special equipment in the production device to disperse the vinyl chloride monomer, and the process is relatively complicated. The latex particle size obtained by the common emulsion method is below 0.2 μm, which cannot meet the requirement of 0.2-1.5 μm particle size of polyvinyl chloride paste resin latex for glove materials. Contents of the invention [0003] The purpose of the present invention is to provide a kind of production method of the polyvinyl chloride paste resin that is used for glove ...
