Abstract
The present invention finds that a detackified natural rubber latex product can be provided by a combination of treatment with a hydrophilic group sealant, coating with a detackifying polymer, halogenation and the like. The present invention also finds that a detackified natural rubber latex product which causes no discoloration of a metallic product surface can be provided by coating it with a detackifying, carboxylated latex vulcanized without using sulfur. The present invention also finds that a detackified natural rubber latex product of controlled protein elution can be provided by chemically modifying protein present in the natural rubber latex with an anionic group, cationic group or the like.
Claims55
A detackified natural rubber latex product, characterized in that both surfaces are provided with a detackified, diene-based carboxylated synthetic rubber latex coating layer.
A detackified natural rubber latex product with one or both surfaces detackified, characterized in that a natural rubber latex is incorporated with a detackifying hydrophilic polymer and/or hydrophilic group sealant.
A detackified natural rubber latex product with one or both surfaces detackified, characterized in that the surfaces of a natural rubber latex product are treated with a hydrophilic group sealant.
A detackified natural rubber latex product with one or both surfaces detackified, characterized in that a natural rubber latex is incorporated with at least one selected from the group consisting of nonionic polymer and anionic polymer, and cationic polymer and ampholytic polymer which cause no gelation of the natural rubber latex, and further with at least one selected from a hydrophilic group sealant and a carboxyl group sealant.
A detackified, lubricating, diene-based carboxylated synthetic rubber latex coat or product with one or both surfaces detackified, characterized in that a lubricating, diene-based carboxylated synthetic rubber latex coat or product, which is incorporated with a reactive, cationic compound or the lubricating, diene-based carboxylated synthetic rubber latex coat or product treated with one or more carboxyl group sealants.
A natural rubber latex product of controlled protein elution, characterized by being treated with a compound which can introduce an anionic and/or cationic group in protein in the natural rubber latex.
A natural rubber latex product of controlled protein elution, characterized by being treated with a waterproofing agent (ketone resin) reactive with protein in natural rubber latex under an alkaline condition and capable of fixing the protein.
