Abstract

A paste resin for producing PVC gloves and a preparation method thereof, the technical points of which are as follows: a certain amount of vinyl chloride monomer is protected by an emulsification system-surfactant, and the materials participating in the polymerization reaction are dispersed in advance by a disperser. It becomes 1-2μm fine liquid particles in water, and under the action of a certain amount of compound initiator, the polymerization reaction is carried out in the range of 40-60°C to produce polymer latex with an average particle size of 1-2μm, and the latex is spray-dried to form a polymer Vinyl chloride paste resin. The paste resin of the invention has the characteristics of stable paste viscosity, suitable yield value, no flow, high tensile strength and high elongation of finished products. The present invention also has the advantages of good viscosity stability of the plastisol and little change over time.

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...
