Embodiment Construction

[0018] The present invention will be further described below in conjunction with embodiment.

[0019] The stress relaxation value of the present invention can be adjusted by adjusting the raw material formula and production process conditions. The amount of zinc oxide and sulfur used in the formulation plays a large role in the stress relaxation properties of the final product: the more zinc oxide content, the higher the strength and modulus of the glove, the lower the elongation, and the higher the stress relaxation value. The lower; the higher the sulfur content, the lower the glove modulus and the higher the stress relaxation value.

[0020] In the implementation of the present invention, at first prepare nitrile latex, get 100 parts of nitrile rubber, 1.8 parts of sulfur, 0.5 part of zinc oxide, 0.5 part of accelerator ZDC, and 0.5 part of BZ. Then the prepared nitrile latex was continuously stirred at room temperature for 24 hours. After drying the glove mold impregnate...

Abstract

A process for preparing the thin and flexible butanenitrile gloves includes such steps as preparing butanenitrile latex from butanenitrile emulsoid, sulfur, zinc oxide and promoter, dipping a mould in coagulant, baking, dipping it in said butannitrile emulsoid, dripdrying, rolling edge, baking, chlorinating, and demoulding.

Description

technical field [0001] The invention relates to a method for manufacturing nitrile gloves, in particular to a method for manufacturing soft and thin nitrile gloves. Background technique [0002] Natural latex gloves have good isolation protection and can effectively prevent the hazards of germs and chemicals, so they have been widely used in the 1980s. However, some people have allergic reactions to natural rubber latex, and Because natural latex gloves are not resistant to solvents and chemicals, people have to develop a variety of gloves made of synthetic materials, such as nitrile, neoprene, PVC, polyurethane gloves and so on. Among them, nitrile gloves are very popular because of their comfortable feel, good strength, and oil resistance. [0003] US Patent No. 6,566,435 discloses a nitrile glove with a stress relaxation greater than 50%. It uses less than 0.5 parts of zinc oxide in nitrile latex and pre-vulcanizes it by heating. The performance...
