A kind of frost-free latex gloves and preparation technology thereof

Abstract

The invention discloses frostless latex gloves and a preparation process thereof, and belongs to the technical field of latex gloves. The frostless latex gloves are prepared by adopting natural rubber latex as a base material, adopting sulfur and a resin vulcanizing agent together as a rubber vulcanizing agent and being matched with given amounts of auxiliary agents, wherein the auxiliary agents comprise an accelerant, an emulsifying agent and an anti-aging agent. By changing the vulcanization system, a crosslinking method is improved, an excess easily-sprayed allowance of a sulfur vulcanization system does not exist in the natural rubber at all, and the intensity of cross bonds is reinforced, so the solvent vulcanized rubber is firmer, and the production of reversion is eliminated, thereby being possible to eliminate frost spray and resulting in that the system is free of frost to spray.

Description

technical field [0001] The invention relates to the technical field of latex gloves, in particular to a frost-free latex glove and a preparation process thereof. Background technique [0002] Latex gloves are a kind of gloves. Latex gloves made of natural latex and other fine additives are widely used in industrial and agricultural production, medical treatment, and daily life. Using natural latex as raw material, whether it is smooth gloves, wrinkled gloves or frosted gloves, there will almost always be "blooming". Caused, that is, in order to obtain products with more ideal performance, adding vulcanizing agent sulfur, accelerator dithiocarbamate and vulcanization activator zinc oxide to natural rubber to make cross-linking between rubber molecules, in order to ensure cross-linking The effect tends to strengthen the amount of the vulcanization system, so that the amount cannot be consumed during the vulcanization reaction of the rubber to form a "surplus".

Problems solved by technology

Using natural latex as raw material, whether it is smooth gloves, wrinkled gloves or frosted gloves, there will almost always be "blooming". Caused, that is, in order to obtain products with more ideal performance, adding vulcanizing agent sulfur, accelerator dithiocarbamate and vulcanization activator zinc oxide to natural rubber to make cross-linking between rubber molecules, in order to ensure cross-linking The effect tends to strengthen the amount of the vulcanization system, so that the amount cannot be consumed during the vulcanization reaction of the rubber to form a "surplus". In addition, the vulcanization of the sulfur vulcanization system and the characteristics of the components of the entire sulfur vulcanization system are easy to spray out , under appropriate circumstances, these "surpluses" will naturally migrate and escape to the rubber surface, causing "blooming" to occur

Surface "blooming" affects the appearance quality and service life of latex gloves, and also causes certain economic losses to the enterprise

[0003] At present, manufacturers of latex gloves generally use the method of blocking to make the "frost" spray out slowly or cover the "frost" in the rubber to delay its spraying time, such as using microcrystalline wax as anti-blooming But it can only play the role of delaying the ejection, and it still needs to migrate and eject, treating the symptoms but not the root cause. Therefore, the development of a latex glove without "blooming" on the surface has a great market application prospect
