Natural emulsion composite slurry and preparation method thereof, protection gloves and preparation method thereof

Abstract

The invention relates to natural emulsion composite slurry. The natural emulsion composite slurry is prepared from natural emulsion and a heat sensitizing agent, wherein the natural emulsion is subjected to pre-sulfurization, and the heat sensitizing agent is diluted by cold water and is a composition comprising one or more of polyvinylmethyl ether, polyether polyformaldehyde dimethyl acetal and polypropylene glycol. The invention further relates to natural emulsion thermosensitive embossed protection gloves prepared from the natural emulsion composite slurry. The natural emulsion composite slurry can not only prevent the gloves from glue penetration during impregnation, avoid damage to the human body, save energy and protect the environment but also prevent liquid from entering the gloves, so that the prepared gloves are soft in texture, light, sensitive and good in breathability, people does not easily feel tired when wearing the gloves for a long time, and therefore the prepared gloves are particularly suitable for mechanical operation; besides, the prepared gloves can have good composite performance of abrasion resistance, cutting resistance, tearing resistance, stabbing resistance, aging resistance and the like, so that influence on the latter aging resistance performance of glove products and blooming are avoided.

Description

technical field [0001] The invention belongs to the technical field of labor protection products, relates to a natural latex composite slurry and a preparation method thereof, and also relates to a natural latex heat-sensitive embossed protective glove prepared from the natural latex composite slurry and a preparation method thereof. Background technique [0002] The current latex protective gloves mainly use chemical wrinkling or physical salt spraying to achieve anti-slip function. Most of these protective gloves use methanol and calcium salt as coagulants, organic solvents as wrinkling agents, and thenardite or sodium chloride. Salt is used as salt spray particles, and through these processing techniques, gloves will penetrate the rubber during the dipping process, and the protective gloves produced not only pollute the environment, but also affect the tear resistance, wear resistance, cut resistance and resistance of the latex film. The comprehensive properties such as p...

[0002] The current latex protective gloves mainly use chemical wrinkling or physical salt spraying to achieve anti-slip function. Most of these protective gloves use methanol and calcium salt as coagulants, organic solvents as wrinkling agents, and thenardite or sodium chloride. Salt is used as salt spray particles, and through these processing techniques, gloves will penetrate the rubber during the dipping process, and the protective gloves produced not only pollute the environment, but also affect the tear resistance, wear resistance, cut resistance and resistance of the latex film. The comprehensive performance such as puncture will cause damage, and some chemical reagents will remain on the gloves, causing serious injury to the user

In addition to this method, the invention patents with patent numbers 201310536861.7 and 201510366002.7 respectively use zinc ammonium complexes as heat-sensitive agents, and zinc oxide in the zinc ammonium complexes is an active agent in natural latex vulcanization, which acts as an activation accelerator. The effect of rubber vulcanization speeds up, which also causes the vulcanization speed of the product to speed up in the later stage, resulting in faster aging of the product, thus affecting the aging performance; Sulfur, accelerators, zinc oxide, etc. in the vulcanization system migrate to the surface of the rubber, causing blooming. Therefore, this method has a greater impact on the later aging performance of the product, and will also cause blooming
