Abstract
The invention relates to a method for the manufacture of a prophylactic article, especially of a glove, from a (carboxylated) diene rubber, according to which a layer of a (carboxylated) diene latex is applied on a former and the (carboxylated) diene latex is cross-linked with a cross-linking agent, which is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the (carboxylated) diene latex.
Claims10
A method for the manufacture of a prophylactic article from a diene rubber or carboxylated diene rubber, according to which a layer of a diene latex or carboxylated diene latex is applied on a former and the diene latex or carboxylated diene latex is exclusively cross-linked with a cross-linking agent comprising organic molecules,
- wherein the cross-linking agent is immobilized on inorganic and/or organic particles with formation of modified particles, and the modified particles are added to the diene latex or carboxylated diene latex,
- wherein exclusively the modified particles are used as cross-linking agents,
- wherein the prophylactic article produced has incorporated the modified particles modified with the cross-linking agent comprising the organic molecules,
- wherein silicate-based particles are used as the inorganic particles, and
- wherein the silicate-based particles are selected from a group consisting of silicates with multivalent cations, zeolites, as well as mixtures thereof.
Prophylactic article comprising a layer of a diene elastomer or carboxylated diene elastomer, wherein the diene elastomer or carboxylated diene elastomer molecular chains of the diene elastomer or carboxylated diene elastomer are exclusively cross-linked covalently via organic molecules and ionically via metal cations, wherein the metal cations are exclusively part of inorganic particles, wherein the organic molecules are exclusively immobilized on the inorganic particles, wherein silicate-based particles are used as the inorganic particles, and wherein the silicate-based particles are selected from a group consisting of silicates with multivalent cations, zeolites, as well as mixtures thereof.
