Problems solved by technology

At present, the emulsion-type paper-plastic composite latex prepared with acrylate as the main body has the characteristics of non-toxicity and non-combustibility, and can replace solvent-based paper-plastic composite glue. However, after this kind of latex is dried into a film, the polymer is insoluble in water. , which brings a lot of inconvenience to equipment cleaning and other process operations, so it is necessary to develop a water-soluble polymer latex to overcome the above shortcomings

Abstract

The invention discloses a water-soluble polymer latex and a preparation method thereof, wherein the water-soluble polymer latex comprises 25-35 parts by weight of butyl acrylate, 1-4 parts of acrylic acid, 1-4 parts of methyl methacrylate, 5 parts, 0.5-1 part of alkylphenol polyoxyethylene ether, 0.2-0.8 part of sodium dodecylsulfonate, 0.1-0.5 part of ammonium persulfate, 0.1-0.5 part of sodium carbonate, 0.5-1 part of sodium hydroxide, 8-15 parts of rosin, 80-90 parts of water. The preparation method is to add alkylphenol polyoxyethylene ether and sodium dodecylsulfonate to water, raise the temperature to 60-70°C, stir and dissolve, then add butyl acrylate, acrylic acid, methyl methacrylate, sodium carbonate, hydrogen Sodium oxide and rosin, continue to stir and mix evenly, finally add ammonium persulfate, continue to stir for 30-40 minutes, cool down to 30-40°C, continue to stir for 10-15 minutes, and discharge.

Description

technical field [0001] The invention belongs to the field of chemical products, and in particular relates to a water-soluble polymer latex and a preparation method thereof. Background technique [0002] Latex generally refers to a colloidal emulsion formed by dispersing polymer particles in water. Also known as latex. It is customary to refer to the aqueous dispersion of rubber particles as latex, and the aqueous dispersion of resin particles as emulsion. Products made from latex are called latex products, such as sponges, gloves, toys, hoses, etc. At present, the emulsion-type paper-plastic composite latex prepared with acrylate as the main body has the characteristics of non-toxicity and non-combustibility, and can replace solvent-based paper-plastic composite glue. However, after this kind of latex is dried into a film, the polymer is insoluble in water. , has brought a lot of inconvenience to technological operations such as equipment cleaning, so it is necessary to d...
