Abstract

The invention provides a synthetic latex glove and a preparation method thereof. The synthetic latex glove is prepared from the following substances: 1-100 parts of a film-forming substance, 0.5 to 10parts of casein, 0.5 to 4 parts of sulfur, 0.5 to 5 parts of an accelerant, 0.5 to 8 parts of zinc oxide, 0.1 to 5 parts of an anti-aging agent, 0.1 to 1 part of pigment, 0.1 to 1 part of potassium hydroxide, 0.1 to 1 part of water glass, 0.1 to 10 parts of a thickening agent, 0.1 to 30 parts of an inorganic filler and 0.1 to 1 part of sodium carboxymethyl cellulose. The invention further discloses a preparation method of the synthetic latex glove. Compared with the prior art, the synthetic latex glove of the invention has the beneficial effects of excellent hot air aging resistance, excellent water permeation resistance, excellent air tightness, excellent mechanical properties, excellent sulfuric acid solution resistance and excellent sodium hydroxide solution resistance. The invention particularly provides a latex formula with aging resistance, air permeation resistance and water permeation resistance and the latex glove prepared from the latex formula. The latex glove is multi-layer and soft, ageing-resistant, air-permeation-resistant and water-permeation-resistant, fits with a hand curve in shape, and is convenient and comfortable to wear and produced by adopting a standard dipping production line.

Description

technical field [0001] The invention belongs to the field of rubber gloves, and in particular relates to a composite latex formula resistant to aging and medium penetration and a glove preparation technology thereof. Background technique [0002] Most of the original industrial or labor protection gloves are made of leather, such as pigskin or cowhide. This kind of gloves is made of hard material, which is not conducive to the bending of laborers' fingers, and is used in some places that require flexible fingers. [0003] With the rapid development of manufacturing technology and materials, especially the development of rubber and composite materials, more and more new varieties have been discovered. According to the material of the gloves, industrial or labor protection gloves can be divided into rubber, steel wire, leather and knitted thread labor protection gloves. Rubber gloves are mainly used in the process of electrician and cleaning because of their anti-corrosion, i...
