[0020] S1. Natural latex 72.8%, nitrile latex 0%, styrene-butadiene latex 0%, potassium hydroxide 1%, casein 2%, sulfur 0.8%, accelerator BZ 1.2%, zinc oxide 5%, anti- Stir 1.8% of oxygen agent, 4.8% of paraffin wax and 3.6% of black pigment evenly to prepare compound latex, and let it stand for 24 hours;

[0021] S2. Add 5% hydroxyethyl cellulose to the latex, and use a rotor viscometer to monitor the latex thickening to 500mPa s;

[0022] S3. Put the palm of the glove liner on the mold, preheat it at 40°C for 10 minutes, immerse it in the anti-seepage agent and air-dry it for 100 seconds, and immerse the glove liner in the compound latex treated in step S2 to form rubber coating;

[0023] S4. After the rubber coating is air-dried, apply anti-slip treatment on its surface, dry it in an oven at 40°C for 15 minutes, then soak it in clean water at 40°C for 80 minutes;

Abstract

The invention provides a preparation method of a pair of high wear-resistant compounded latex gloves, and relates to the technical field of preparation technologies of gloves. The method comprises the following steps: S1, evenly mixing natural latex, butadiene-acrylonitrile latex, styrene-butadiene latex, potassium hydroxide, casein, sulfur, an accelerant BZ, zinc oxide, an antioxidant, paraffin and black pigment according to a weight ratio to obtain compounded latex; S2, adding hydroxyethyl cellulose into the obtained latex; S3, sleeving the palm of an inner container of each glove on a mold, preheating, immersing in an anti-seepage agent and then air-drying, and immersing in the compounded latex to form a rubber coating; S4, after the rubber coating is air-dried, carrying out anti-slip treatment on the surface of the rubber coating, drying in an oven and then immersing in clean water; S5, placing the inner containers, treated in step S4, of the gloves in the oven, drying and vulcanizing, and carrying out demoulding treatment to obtain the glove product. The compounded latex gloves prepared by the method provided by the invention are good in softness and long in service life.

Description

technical field [0001] The invention belongs to the technical field of glove preparation technology, and in particular relates to a preparation method of high wear-resistant latex gloves. Background technique [0002] Latex gloves are a kind of gloves, which are processed from latex. It can be used in household, industrial, medical, beauty and other industries, and it is a necessary hand protection product. Latex gloves made of natural latex and other fine additives. After special surface treatment, the products are comfortable to wear and are widely used in industrial and agricultural production, medical treatment and daily life. At present, the traditional rubber compounding method is formulated with natural rubber latex, and the gloves produced by using it have poor wear resistance. The EN388 wear resistance level generally can only reach level 2, and the service life is short. [0003] Therefore be badly in need of providing a kind of making glove softness good, the pr...
