Pre-vulcanizing technology of latex medical gloves

Abstract

The invention discloses a pre-vulcanizing technology of latex medical gloves. The pre-vulcanizing technology comprises the following steps of (1) preparing a 10% potassium hydroxide solution; (2) preparing a 50% sulfur dispersion; (3) preparing a 30% zinc diethyl dithiocarbamate dispersion; (4) preparing a 50% zinc oxide dispersion; (5) preparing a 30% anti-aging agent dispersion; (6) weighing 100 parts of natural latex, 1 part of 10% potassium hydroxide solution prepared in step (1), 1 part of 50% sulfur dispersion prepared in step (2), 1 part of 30% zinc diethyl dithiocarbamate dispersion prepared in step (3), 0.72 part of 50% zinc oxide dispersion prepared in step (4), and 1.5 parts of 30% anti-aging agent dispersion prepared in step (5) in parts by mass, feeding into a vulcanizing tank, heating to 45 DEG C, warming for 12h, putting the warmed latex into the vulcanizing tank, and standing for 48h; (7) adjusting the raw material obtained in step (6), testing the total oxygen and chloroform numbers, and standing by further use. The latex raw material prepared by the technology has the advantages that the elasticity is good, the anti-corrosive property is realized, the anti-aging effect is good, and the service life is long.

Description

technical field [0001] The invention relates to a pre-vulcanization process for latex medical gloves. Background technique [0002] Latex gloves are a kind of gloves. They are different from ordinary gloves and are made of latex. It can be used in household, industrial, medical, beauty and other industries, and it is a necessary hand protection product. Latex gloves made of natural latex and other fine additives. After special surface treatment, the products are comfortable to wear and are widely used in industrial and agricultural production, medical treatment and daily life. The rubber is first sliced ​​by the rubber mixer, and then sent to the colloidal sol cylinder and gasoline to mix the sol. After the sol is emulsified and prepared, it is pumped to the latex tundish. The rubber solution dissolved in gasoline is sent from the top of the distillation tower, and is heated and distilled by steam. The light component gasoline is heated into a gas phase, and the gasoline ...

AI Technical Summary

Problems solved by technology

[0003] At present, the raw materials made by the pre-vulcanization process of latex gloves have poor elasticity, are not resistant to corrosion, have poor anti-aging effects, and have a short service life.
