Elastomer product with covalently bonded particles
The invention relates to a method of bonding particles to the surface of an elastomer, in particular a glove, the surface of the elastomer being at least partially epoxidized, and the particles are covalently bonded to the epoxide groups after epoxidation of the elastomer surface.
1. A method of bonding particles to the surface of an elastomer comprising: forming an at least partially epoxidized elastomer surface by epoxidizing the surface of an elastomer and applying particles to the at least partially epoxidized elastomer surface, wherein the particles are covalently bond to the at least partially epoxidized elastomer surface.
2. The method according to claim 1 , wherein the particles are inorganic particles.
3. The method according to claim 1 , wherein the surface of the particles is functionalized prior to applying the particles to the surface of the at least partially epoxidized elastomer surface.
4. The method according to claim 3 , wherein the particles are functionalized by creating free mercapto groups and/or free amino groups and/or carboxylic acid groups and/or epoxide groups and/or hydroxy groups and/or anhydride groups and/or isocyanate groups and/or isothiocyanate groups on the surface of the particles.
5. The method according to claim 3 , wherein the particles are functionalized by at least one chemical compound selected from the group consisting of 3-aminopropyltrimethoxysilane, 3-mercaptopropyltriethoxysilane, hydroxymethyltriethoxysilane, 3-isocyanate propyltrimethoxysilane, 3-glycidoxypropyltrimethoxysilane, and 3-(triethoxysilyl)propylsuccinic anhydride.
6. The method according to claim 1 , wherein particles that are purely adhesively bonded particles to the surface of the elastomer are removed.
7. The method according to claim 1 , wherein the elastomer is in solid form when forming the at least partially epoxidized elastomer surface.
8. The method according to claim 1 , wherein the elastomer is in liquid phase when forming the at least partially epoxidized elastomer surface.
9. The method according to claim 1 , wherein epoxidation is effected on discrete regions of the surface of the elastomer when forming the at least partially epoxidized elastomer surface.
10. The method of claim 1 , wherein the elastomer is in the form of a glove.
