Problems solved by technology

However, the fly in the ointment is that the modulus of nitrile rubber gloves is large at low elongation, and the restraint of the opponent is large, which is easy to wear and fatigue.
Secondly, nitrile rubber gloves have poor air permeability and moisture permeability, and it is easy to damage the skin of the hands when worn for a long time
Polyurethane gloves not only have the advantages of good oil and weather resistance and good anti-bacterial permeability of nitrile rubber gloves, but also have good breathable and moisture-permeable characteristics. However, due to the high price and small market share, they have not replaced nitrile rubber gloves. preferred

Abstract

A process for preparing the expendable composite nitrile rubber-polyurethane glove includes generating a layer of nitrile rubber film on a mould, and dipping it in aquatic polyurethane emulsion. The resultant glove has high resistance to oil and bacterial osmosis, high weatherability, and high air and moisture permeability.

Description

technical field [0001] The invention relates to a manufacturing method of a disposable nitrile rubber-polyurethane composite glove and its use, especially a thin disposable nitrile rubber-polyurethane composite glove with a thickness of less than 0.09mm and polyurethane accounting for 5-10% of the total weight of the glove The manufacturing method and its use. Background technique [0002] With the continuous improvement of people's self-protection awareness, more and more people use disposable gloves in hospitals, food processing, electronic assembly and other places. At present, there are mainly four types of disposable gloves used by people: PVC gloves, natural rubber gloves, nitrile rubber gloves and polyurethane gloves. PVC gloves are cheap, but have poor protection, especially causing "white trash" problems to the environment. Natural rubber gloves are limited by the insufficient supply of natural materials, and the price continues to rise, especially the problem of ...
