Preparation process of polyvinyl chloride and butyronitrile rubber composite gloves

Abstract

The invention relates to a preparation process of polyvinyl chloride and butyronitrile rubber composite gloves. The preparation process comprises the following steps: step I, pouring a plasticizer into a stirring tank through a first feed opening, and pouring liquid butyronitrile rubber into the stirring tank through a second feed opening to form a first mixture; step II, pouring polyvinyl chloride into the stirring tank through a third feed opening, adding a stabilizer and a viscosity reducer through the first feed opening, controlling a regulator, and performing uniform stirring to form a second mixture; step III, opening a control valve of the stirring tank to make the second mixture enter a dipping tank for dipping and performing drying to form glove crude products; and step IV, spraying titanium dioxide and blue color paste to the dried glove crude products through a spraying device, and performing heating and cooling to form the polyvinyl chloride and butyronitrile rubber composite gloves. Accordingly, the tensile property, oil resistance and cold resistance of the polyvinyl chloride and butyronitrile rubber composite gloves can be effectively improved, and compared with preparation of gloves with the same performance, the preparation process can reduce cost, and is simple.

Description

technical field [0001] The invention relates to the field of gloves preparation technology, in particular to a preparation technology of polyvinyl chloride nitrile rubber composite gloves. Background technique [0002] Polyvinyl chloride (PVC) has a wide range of raw materials, low product cost, light weight, convenient construction and maintenance, and is the second general-purpose plastic. However, PVC materials have disadvantages such as poor toughness and poor heat resistance, which restrict their development in fields with high performance requirements. Nitrile rubber is produced by emulsion polymerization of butadiene and acrylonitrile. Nitrile rubber is mainly produced by low-temperature emulsion polymerization. It has excellent oil resistance, high wear resistance, good heat resistance and strong adhesion. , its disadvantages are poor low temperature resistance, poor ozone resistance, poor insulation performance, and slightly lower elasticity. [0003] Due to the l...

AI Technical Summary

Problems solved by technology

[0004] At present, there are already some preparation processes for composite rubber gloves. The rubber gloves prepared by most of the preparation processes have good wear resistance and low temperature resistance. The color is uneven, the tensile properties are too high or too low, resulting in the prepared gloves being too soft or too hard, and the overall cost performance is not high
