Gloves against mineral oils and mechanical hazards: composites of carboxylated acrylonitrile–butadiene rubber latex
نویسندگان
چکیده
Resistance to permeation of noxious chemical substances should be accompanied by resistance to mechanical factors because the glove material may be torn, cut or punctured in the workplace. This study reports on glove materials, protecting against mineral oils and mechanical hazards, made of carboxylated acrylonitrile-butadiene rubber (XNBR) latex. The obtained materials were characterized by a very high resistance of the produced materials to oil permeation (breakthrough time > 480 min). The mechanical properties, and especially tear resistance, of the studied materials were improved after the addition of modified bentonite (nanofiller) to the XNBR latex mixture. The nanocomposite meets the requirements in terms of parameters characterizing tear, abrasion, cut and puncture resistance. Therefore, the developed material may be used for the production of multifunctional protective gloves.

Influence of latex – oil interactions on offset ink setting and component distribution on coated paper
It is mainly the bulk properties of latex and ink oil that contribute to the observable differences in the ink setting dynamics rather than surface chemical wetting differences or changes in porous structure related to the inclusion of latex. It can be generalised that low latex solubility parameter (butadiene < styrene = acrylate < acrylonitrile) leads to greater oil interaction. Furthermore, ...

Tertiary amine-modified corn starches were converted to their basic or hydroxide form and combined with carboxylated butadiene-acrylonitrile copolymer and butadiene-styrene-sulfonic acid polymer to produce ionically bonded filler-elastomer composites. An increasing percentage of the elastomer fraction in the starch-elastomer composite is insolubilized as the starch-to-elastomer ratio increases....
