Abstract

The invention discloses a double-layered latex glove. The double-layered latex glove is characterized by comprising an inner contact layer and an outer working layer, wherein the inner contact layer is prepared from the following raw materials in parts by weight: 580 to 650 parts of low-protein natural latex, 3 to 4 parts of potassium hydroxide, 5 to 7 parts of sulfur, 2 to 4 parts of an accelerant, 5 to 7 parts of zinc oxide, 5 to 8 parts of an anti-ageing agent, 3 to 4 parts of titanium white, 0 to 4 parts of a coloring agent and 2 to 3 parts of a de-foaming agent; the outer working layer isprepared from the following raw materials in parts by weight: 80 to 120 parts of butyronitrile latex, 1.0 to 2.0 parts of sulfur, 1.0 to 3.0 parts of a plasticizer, 0.5 to 3.0 parts of zinc oxide, 0.5 to 5.0 parts of pearl powder and 0.0 to 0.6 part of color paste. The double-layered latex glove disclosed by the invention has relatively good acid and alkali resistance and wear resistance of the outer working layer and the utilization performance of the glove becomes good; meanwhile, the inner contact layer made of the latex is more fitted to hands of people and the double-layered latex gloveis softer and more comfortable.

Description

technical field [0001] The invention relates to the field of latex glove processing, in particular to a double-layer latex glove and a preparation method thereof. Background technique [0002] Latex generally refers to a colloidal emulsion formed by dispersing polymer particles in water. Also called latex. It is customary to call an aqueous dispersion of rubber particles a latex, and an aqueous dispersion of resin particles as an emulsion. Products made of latex are called latex products, such as gloves, toys, hoses, etc. [0003] Gloves have been widely used in people's production and life due to their barrier protection function, which can well protect the safety of users. According to its different uses, it can be divided into medical gloves, industrial gloves and household gloves, and gloves are generally divided into two categories: natural rubber gloves and nitrile gloves according to the different materials used in production. [0004] As disclosed in the Chinese ...
