Abstract

The invention provides a compounded rubber glove. The compounded rubber glove includes a fiber glove lining; a surface of the fiber glove lining is coated with a butyronitrile latex layer; a surface of the butyronitrile latex layer is coated with a polyvinyl chloride slurry layer; a surface of the polyvinyl chloride slurry layer is coated with a waterborne polyurethane emulsion layer so as to form a polyurethane film; the surface of the fiber glove lining is coated with the butyronitrile latex layer in a dipping manner; and the surface of the butyronitrile latex layer is coated with the polyvinyl chloride slurry layer through a spraying manner. The inventive concept of the invention adopts a three-compounded layer structure to improve a single slurry layer to prepare the rubber glove; the prepared compounded layer has the characteristics of a butyronitrile rubber glove such as excellent softness, low stress at definite elongation, and high breaking strength, and has the characteristics of a polyvinyl chloride glove such as the chemical stability and the flame retardant performance; and the waterborne polyurethane slurry can enable the compounded rubber glove to possess the fatigue durability, the abrasive resistance, the high elasticity, the excellent permeability, and high strength.

Description

technical field [0001] The invention belongs to the field of rubber gloves, in particular to a composite rubber glove and a preparation method thereof. Background technique [0002] Rubber gloves are widely used in various fields of society, such as hospitals, households, electronics industry, food industry, gardening and planting, mainly to isolate pollution and protect hands. Traditional rubber gloves are divided into several types according to the raw materials used - rubber materials, such as: latex gloves, which use natural latex as the main raw material; As the main raw material; styrene-butadiene gloves are made of synthetic latex polymerized from butadiene and styrene emulsion as the main raw material. [0003] Nitrile rubber has high puncture resistance, hook resistance, high comfort and dexterity, and strong chemical resistance, so gloves with nitrile rubber surface treatment are widely used in Automation, aviation, printing, chemical, petroleum, wire and cable a...
