Abstract

A paste resin for producing PVC gloves and its production are disclosed. The process is carried out by making chlorethylene monomer under emulsifier system-surface activator protection, dispersing materials into water to become 1-2mum fine grain by disperser, polymerization reacting at 40-60degree under action of composite initiating agent to generate polymer latex with average grain diameter 1-2mum, and spray drying by latex to obtain the final product. It is stable, has no fluid, and has proper yield value and better tensile strength.

Description

technical field [0001] The invention belongs to the technical field of macromolecule chemical industry, and in particular relates to a paste resin for producing (dipping method) PVC gloves prepared by a microsuspension polymerization method and a preparation method thereof. Background technique [0002] At present, there are many production methods for domestic polyvinyl chloride paste resin products, among which the main methods are emulsion polymerization and microsuspension polymerization. It produces many grades of paste resin products, which are mainly used in coating, foam molding, slush molding, dipping and rotary molding, and other processing techniques to produce artificial leather, floor leather, wallpaper, flame-retardant conveyor belts, toys and other products. [0003] Dip-molded PVC gloves are used for labor protection of medical personnel and other industries. Due to allergic reactions to white skin of traditional latex gloves, PVC gloves are exported to the U...
