Embodiment

[0290] The purpose of the following experiments is to find out the necessary conditions when using alkali metal hydroxides as pH regulators to manufacture polycarbodiimide cross-linked gloves. In addition, at the same time, it is also to confirm the performance of the obtained glove.

[0291] In the following experiment, using the composition for dip molding whose pH was adjusted to 10.0 and 10.5 with alkali metal hydroxide (specifically, potassium hydroxide), it was confirmed that the film obtained by changing the temperature and time of leaching performance.

[0292] In addition, the contents of Zn, Ca, and K in the obtained film were quantified, and the relationship between the amount and the performance of the film was confirmed. In addition, even when an alkali metal hydroxide such as potassium hydroxide is used, conditions under which a glove having a film thickness of 50 to 100 μm can be provided with practical performance have been studied.

[0293] In the following ...

Abstract

Provided is a method for manufacturing a glove, including (1) a step for dipping a glove molding die into a coagulant solution including calcium ions and causing the coagulant to adhere to the glove molding die, (2) a dispersing step for leaving a dip molding composition to stand while stirring the dip molding composition, (3) a dipping step, (4) a gelling step, (5) a leaching step, (6) a beadingstep, (7) a precuring step, and (8) a curing step, the steps of (3) through (8) above being performed in the above order, and the dip molding composition having a specific composition.

Description

technical field [0001] The present invention relates to a composition for dip molding, a method for producing gloves, and gloves. Background technique [0002] Conventionally, there are Patent Documents 1 to 6 regarding techniques for producing gloves by dip molding using polycarbodiimide as an organic crosslinking agent for carboxylated acrylonitrile butadiene copolymer (hereinafter also referred to as XNBR). Documented technical solutions. Hereinafter, gloves obtained by crosslinking polycarbodiimide are also referred to as "polycarbodiimide crosslinked gloves". [0003] Conventional rubber gloves cross-linked with sulfur and accelerators such as thiuram mixtures and thiazoles as sulfur-based vulcanization accelerators have type IV allergies, so accelerator-free gloves have been studied to replace them. The techniques described in Patent Documents 1 to 6 utilize covalent bonds formed by the reaction of polycarbodiimide. [0004] In these patent documents, when producing...
