Problems solved by technology

[0002] China is the production base of labor insurance gloves in the world. This industry consumes a lot of paste resin, and currently only Swedish P737 can be used alone, but the price is relatively high. Domestic red powder can partially replace P737, but there is a phenomenon of dull gloves. Therefore, most manufacturers use more than 3 kinds of paste resins for mixed use to meet the requirements.

Embodiment Construction

[0021] Specific implementation 1

[0022] (1) Add the vinyl chloride monomer of 12Kg, the deionized water of 12Kg, the potassium persulfate of 10g, the sodium bisulfite of 10g, the sodium lauryl sulfate of 160g, the ammonium bicarbonate of 5g by above-mentioned formula.

[0023] (2) Then the polymerization kettle is evacuated and deoxidized, vinyl chloride monomer is added according to the formula, the temperature of the polymerization kettle is raised to 50-63°C, and sodium lauryl sulfate is continuously added during the polymerization process;

[0024] (3) Add the potassium persulfate solution dissolved in water continuously into the polymerization kettle, keep stirring, and carry out the polymerization reaction, control the reaction at 58.0°C, when the pressure of 0.89MPa starts to drop, when the pressure drops to 0.45MPa, the reaction ends ;

[0025] (4) After the reaction finishes, earlier the unreacted vinyl chloride monomer is reclaimed to the gas cabinet, and the late...

Abstract

The invention discloses a method for preparing paste resin with medium viscosity. The method comprises the following steps: producing the paste resin by using an emulsion polymerization method; adding a monomer and aids into a polymerizing kettle according to a formula proportion; performing vacuumizing and deoxidation, raising the temperature to 50-63 DEG C under a stirring state, performing polymerization reaction at the temperature of 50-63 DEG C, starting to reduce the pressure of 0.83MPa, and ending the reaction when the pressure is reduced to 0.4MPa. The method is characterized in that 1, the tensile strength of leather working gloves produced by using the paste resin with the medium viscosity is higher than that of common leather working gloves; 2, the glossiness of the leather working gloves produced by using the paste resin with the medium viscosity is higher than that of the common leather working gloves; 3, compared with other processes, a process of producing the leather working gloves produced by using the paste resin with the medium viscosity has the advantages of moderate viscosity and simplicity in de-foaming.

Description

technical field [0001] The invention belongs to the technical field of polymer chemical industry, and specifically relates to a production method for preparing medium-viscosity paste resin by using an emulsion method. Background technique [0002] China is the production base of labor insurance gloves in the world. This industry consumes a lot of paste resin, and currently only Swedish P737 can be used alone, but the price is relatively high. Domestic red powder can partially replace P737, but there is a phenomenon of dull gloves. Therefore, most manufacturers use more than 3 kinds of paste resins for mixed use to meet the requirements. The annual consumption of resin in this industry should be more than 100,000 tons, and the consumption of non-lined imitation rubber labor protection gloves is more than 20,000 tons. At present, imitation rubber labor protection gloves require paste resin with high viscosity and easy degassing, and the products are shiny. Every year, new pro...
