Problems solved by technology

[0003] The existing medical gloves cannot have oil resistance and wearability at the same time. Therefore, people think of mixing two latexes with different properties to make gloves, so as to have the properties of the two latexes, but the mechanical stability of the two latexes mixed Both chemical and chemical stability are unstable, making the finished product unstable and unable to reach the ideal state

Embodiment 1

[0056] A preparation method of mixed latex medical gloves, comprising the steps of:

[0057] 1. Prepare raw materials such as sulfur dispersion, anti-aging agent dispersion, zinc oxide dispersion and zinc butyl dithiocarbamate (BZ) dispersion, as follows:

[0058] Preparation of sulfur dispersion: add demineralized water, dispersant NF, potassium hydroxide and sulfur into the grinder in turn, and grind for 36 hours to obtain sulfur dispersion; the speed of the grinder is 300-400 rpm, and the glass in the grinder The diameter of the sand is 3-5mm, and the volume of glass sand accounts for 1 / 2 of the volume of the grinder; among them, 100 parts of sulfur, 0.1 parts of potassium hydroxide, 5.0 parts of dispersant NF, and 94.9 parts of demineralized water are prepared into the mass of sulfur 50% sulfur dispersion.

[0059] Preparation of anti-aging agent dispersion: Add demineralized water, dispersant NF, potassium hydroxide and anti-aging agent WL into the grinder in turn, and g...

Abstract

The invention provides a preparation method for mixed latex medical gloves, and particularly relates to the technical field of glove preparation. The preparation method comprises the following steps:preparing a mixed matched latex, namely separately preparing two latexes with different properties into matched latexes, then mixing two prepared matched latexes in a latex tank in proportion, and carrying out filtering for subsequent usage; and preparing the mixed latex medical gloves from a prepared mixed compound latex. According to the invention, two latexes are independently prepared; different stabilizers and vulcanization accelerators are added according to the properties of the latexes; two prepared matched latexes are matched according to different proportions; thus, two latexes are continuously stable in the production process; and a rubber film is consistent in vulcanization speed in the vulcanization process.

Description

technical field [0001] The invention belongs to the technical field of glove preparation, and in particular relates to a preparation method of mixed latex medical gloves. [0002] technical background [0003] The existing medical gloves cannot have oil resistance and wearability at the same time. Therefore, people think of mixing two latexes with different properties to make gloves, so as to have the properties of the two latexes, but the mechanical stability of the two latexes mixed And chemical stability is all unstable, makes the product of making unstable, can't reach ideal state. [0004] Therefore, be badly in need of a kind of preparation method of the mixed latex medical glove that solves existing problem. Contents of the invention [0005] The purpose of this invention is to propose a kind of preparation method of mixed latex medical gloves, take two kinds of latexes to prepare separately, add different stabilizing agent and vulcanization accelerator according to...
