Abstract

Abstract This invention relates to a method for manufacturing a granular organic rubber composition which is useful for a vulcanizing agent, a vulcanization accelerator and antioxidant etc. by contacting an organic rubber chemical mixture comprising a rubber chemical, a liquid polybutene, a nonionic or anionic surface active agent and a water-soluble anionic macromolecule with an aqueous solution containing an alkaline earth metal salt and/or a zinc salt.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 135 words
A method for manufacturing a granular organic rubber chemical composition characterized in that an organic rubber chemical mixture consisting of an organic rubber chemical selected from the group consisting of a vulcanizing agent, a vulcanizing accelerator and an antioxidant and, relative to this organic rubber chemical, 5 to 45 wt % of a liquid polybutene which is of mean molecular weight of 200 to 10,000 and of viscosity not exceeding 37,000 centi-stokes at 100° F., 0.1 to 20 wt % of a nonionic or an ionic surface active agent and 0.1 to 2 wt % of a water-soluble anionic macromolecule which contains a carboxyl group or a hydroxyl group within the molecule thereof is hardened by bringing the mixture into contact with an aqueous solution containing an alkaline earth metal salt and/or a zinc salt.
Claim 2
Independent Claim 135 words
A method for manufacturing a granular organic rubber chemical composition characterized in that an organic rubber chemical mixture consisting of an organic rubber chemical selected from the group consisting of a vulcanizing agent, a vulcanizing accelerator and an antioxidant and, relative to this organic rubber chemical, 5 to 45 wt % of a liquid polybutene which is of mean molecular weight of 200 to 10,000 and of viscosity not exceeding 37,000 centi-stokes at 100° F., 0.1 to 20 wt % of a nonionic or an ionic surface active agent and 0.1 to 2 wt % of a water-soluble anionic macromolecule which contains a carboxyl group or a hydroxyl group within the molecule thereof is hardened by bringing the mixture into contact with an aqueous solution containing an alkaline earth metal salt and/or a zinc salt.
Claim 3
Dependent Claim 42 words
A method for manufacturing a granular organic rubber chemical composition according to claim 1, wherein said organic rubber chemical mixture is hardened and granulated by dropping the mixture into said aqueous solution containing the alkaline earth metal salt or the zinc salt.
Claim 4
Dependent Claim 46 words
A method for manufacturing a granular organic rubber chemical composition according to claim 1, wherein said organic rubber chemical mixture is granulated prior to hardening the mixture by bringing it into contact with the aqueous solution containing the alkaline earth metal salt or the zinc salt.
Claim 5
Independent Claim 153 words
A method for manufacturing a granular organic rubber chemical composition characterized in that an organic rubber chemical mixture consisting of an organic rubber chemical selected from the group consisting of a vulcanizing agent, a vulcanizing accelerator and an antioxidant and, relative to this organic rubber chemical, 5 to 45 wt % of a liquid polybutene which is of mean molecular weight of 200 to 10,000 and of viscosity not exceeding 37,000 centi-stokes at 100° F., 0.1 to 20 wt % of a nonionic or anionic surface active agent, 0.1 to 8 wt % of a water-soluble anionic macro-molecule which contains a carboxyl group or a hydroxyl group within the molecule thereof and 30 wt % or less than that of process oil, an ethylene-vinyl acetate copolymer, paraffin wax or a plasticizer is hardened by bringing the mixture into contact with an aqueous solution containing an alkaline earth metal salt or a zinc salt.
Claim 6
Independent Claim 153 words
A method for manufacturing a granular organic rubber chemical composition characterized in that an organic rubber chemical mixture consisting of an organic rubber chemical selected from the group consisting of a vulcanizing agent, a vulcanizing accelerator and an antioxidant and, relative to this organic rubber chemical, 5 to 45 wt % of a liquid polybutene which is of mean molecular weight of 200 to 10,000 and of viscosity not exceeding 37,000 centi-stokes at 100° F., 0.1 to 20 wt % of a nonionic or anionic surface active agent, 0.1 to 8 wt % of a water-soluble anionic macro-molecule which contains a carboxyl group or a hydroxyl group within the molecule thereof and 30 wt % or less than that of process oil, an ethylene-vinyl acetate copolymer, paraffin wax or a plasticizer is hardened by bringing the mixture into contact with an aqueous solution containing an alkaline earth metal salt or a zinc salt.
Claim 7
Dependent Claim 42 words
A method for manufacturing a granular organic rubber chemical composition according to claim 4, wherein said organic rubber chemical mixture is hardened and granulated by dropping the mixture into said aqueous solution containing the alkaline earth metal salt or the zinc salt.
Claim 8
Dependent Claim 46 words
A method for manufacturing a granular organic rubber chemical composition according to claim 4, wherein said organic rubber chemical mixture is granulated prior to hardening the mixture by bringing it into contact with the aqueous solution containing the alkaline earth metal salt or the zinc salt.
