Definitions
- the present invention relates to an electrostatically dissipative protective glove and a method for producing a corresponding protective glove.
- electrostatically dissipative gloves play a special role. For example, in explosion-proof work areas, it must be ensured that any electrostatic charges that arise are discharged.
- dispersions with elongated particles such as carbon nanotubes can be used, which are effective in smaller quantities due to their anisotropic properties.
- the disadvantage of using carbon nanotubes is that they have to be added to the polymer compound in highly dilute dispersions in order to counteract agglomeration of the carbon nanotubes. Dispersions that have less than 5% carbon nanotubes are common. Correspondingly, a larger amount of the dispersion has to be used, which is only possible by reducing the polymer content in the polymer compound. The reduction in the polymer content, however, results in undesirable changes in properties, such as the pH value or viscosity of the polymer compound.
- the object of the invention is to provide an electrostatically dissipative protective glove with a polymeric foam layer, the polymeric foam having improved stability. Furthermore, the invention is based on the object of providing a method for producing the protective glove according to the invention.
- the protective glove according to the invention consists of at least two layers, with a first layer being a polymeric foam layer.
- the polymer foam layer contains carbon fibers, which reduce the volume resistance. Carbon fibers are particularly suitable for this application because, due to their elongated shape, fewer conductive paths can be formed within the polymer matrix than spherical particles. It is sufficient to add significantly less carbon fibers to the latex compound in order to produce the desired through resistance.
- carbon fibers can be added directly to the latex compound without first being dissolved in a dispersion would have to.
- the influence of the additive on the properties of the latex compound for example polymer content, viscosity and pH value, and thus on the processability, is negligible.
- the mechanical properties of the finished glove are also not significantly impaired by the addition of the carbon fibers.
- the carbon fibers in contrast to commercially available conductive additives, lead to increased foam stability. This means that the foam and thus also the product quality are stable over a longer period of time than with a compound without carbon fibers.
- the carbon fibers are preferably comminuted carbon fibers with a length between 10 pm and 100 pm, particularly preferably between 50 pm and 250 pm.
- the fibers can be cut or ground, for example.
- the diameter of the carbon fibers is significantly smaller than their length, preferably between 2 pm and 25 pm, particularly preferably between 3 pm and 9 pm.
- fiber bundles made of several individual carbon fibers the overall diameter of which can be larger, for example larger than 100 pm.
- Other electrically conductive synthetic or natural fibers that are, for example, metallized or coated with conductive material and are available in a wide variety of geometries are also obvious to the person skilled in the art.
- the foam layer can consist of synthetic or natural polymers.
- the polymeric foam layer preferably comprises nitrile, chloroprene, isoprene, natural rubber, polyurethane rubber, or a mixture of one or more of these components.
- the polymeric foam coating can preferably contain further additives, such as, for example, crosslinking aids, thickeners or color pigments.
- the polymer foam layer particularly preferably consists essentially of nitrile rubber.
- the polymeric foam layer is foamed, ie it contains gas inclusions. It can be closed-cell foam or open-cell foam or a mixture of both forms. The inclusions can contain air or another gas or gas mixture and have been introduced in various ways. Foam mixers or chemical foaming, for example, are familiar to those skilled in the art.
- the second layer of the glove consists of a textile carrier material.
- a textile carrier material for example, increase wearing comfort or offer protection against cuts.
- the textile carrier is in contact with the user's skin, while the polymer foam layer forms the outer layer of the glove.
- conductive games are incorporated into the textile carrier material.
- the conductive games produce the conductivity of the textile carrier.
- Suitable materials for the conductive game can, for example, be of a metallic nature (e.g. steel, copper or silver), contain carbon fibers and be metalized or otherwise conductively modified games.
- the protective glove comprises a further, non-foamed polymer layer as a second layer in addition to the foam layer according to the invention.
- a non-tricot glove can be provided by using a non-foamed polymer layer as a carrier for the foam layer according to the invention. This is useful for chemical protection gloves, for example.
- the non-foamed polymer layer in this embodiment can optionally be modified to be electrically conductive.
- the protective glove can also consist of a multilayer system which comprises a textile carrier, one or more non-foamed polymer layers and the foam layer according to the invention. All additional layers can also be modified to be electrically conductive.
- the protective glove comprises, for example, an unfoamed polymer layer between the textile carrier and the polymeric foam layer according to the invention.
- the high level of comfort of the textile can be combined with the waterproofness of the unfoamed layer and the conductivity of the polymer layer according to the invention.
- the volume resistance of the protective glove according to the invention is less than 10 8 ohms. This corresponds to the requirements for protective gloves from DIN EN 16350. According to the invention, this volume resistance can be achieved with a solids content of the carbon fibers in the latex compound of less than 4% by weight.
- the method according to the invention for producing a protective glove according to the invention comprises the following steps relating to the nitrile rubber foam layer.
- a latex compound is provided. It is about preferably a latex compound containing nitrile rubber. Carbon fibers are added to the latex compound. The carbon fibers do not require a suspension, but are added directly to the latex compound without causing undesired agglomeration.
- the compound is foamed.
- the foaming is preferably carried out in a foam mixer by mechanically incorporating defined volumes of air into the latex compound. The added carbon fibers increase the stability of the foam.
- the foamed mass is then pumped into a plunge pool.
- a hand-shaped immersion form is provided and dipped into the foamed latex compound in which the carbon fibers are contained.
- the dipping form can also have been treated with a coagulating saline solution before diving.
- the glove is then dried and removed.
- a hand-shaped dipping form is provided and preheated.
- the dipping mold is preferably made of aluminum or ceramic.
- a knitted glove made of a textile carrier material is pulled onto the preheated dipping mold.
- the knitted glove is preferably interspersed with conductive yarns.
- the knitted glove is particularly preferably designed in one piece, ie as a so-called “seamless” glove.
- the dipping form with the knitted glove is immersed in a coagulating salt solution. The coagulant prevents the rubber foam from completely penetrating the textile backing before the latex compound begins to coagulate.
- the dipping form is pulled out of the salt solution and dried.
- the dipping form with the dried knitted glove is then put into the foamed latex compound, which contains the carbon fibers, immersed.
- the dipping form is then pulled out of the latex compound and pre-dried.
- the dipping mold with the textile carrier that is now coated is then immersed in a water bath in order to remove the excess coagulant.
- the dipping form with the coated textile carrier is dried, preferably at temperatures from 100.degree. C. to 130.degree.
- the finished protective glove is removed from the dipping form.
- the knitted glove on the hand mold is first dipped into the coagulating salt solution, dried and dipped into an unfoamed coating compound.
- the coated glove is then dipped into the foamed latex compound, which contains the carbon fibers.
- the dipping form is then pulled out of the latex compound, pre-dried, washed, dried and finally removed from the form.
- the solids content of the carbon fibers in the latex compound is preferably less than 4.0% by weight, particularly preferably between 4.0% by weight and 1.0% by weight. It is advantageous that with such a low solid content, the mechanical properties of the foam are not negatively influenced, but rather the stability of the foam is even increased.
- FIG. 1 An exemplary embodiment of a glove according to the invention is shown schematically in FIG.
- a tricot-coated protective glove with a nitrile rubber foam layer 1 and a textile carrier material on the inside 2 can be seen.
