Abstract
A reinforced elastic body is disclosed, which comprises a chlorosulfonated polyolefin reinforced with polyester fibers having an adhesive containing an isocyanate compound and/or an epoxy compound and an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer. Also, a production process of the reinforced elastic body is disclosed, which comprises vulcanizing-adhering polyester fibers treated with an adhesive containing an isocyanate compound and/or an epoxy compound and then treated with an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer to a chlorosulfonated olefin compounded material.
Claims6
A reinforced elastic body consisting essentially of a chlorosulfonated polyolefin reinforced with polyester fibers having an adhesive containing an isocyanate compound and an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer latex, wherein the molar ratio of resorcin to formaldehyde is from 1:0.1 to 1:5, and the solid component weight ratio of the latex to the sum of resorcin and formaldehyde is from 1/100 to 1/1.
A process of producing a reinforced elastic body comprising a chlorosulfonated polyolefin reinforced with polyester fibers having an adhesive containing an isocyanate compound and an adhesive composed of a liquid mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer latex, which process consists essentially of vulcanizing-adhering the chlorosulfonated polyolefin and the polyester fibers treated with an adhesive containing an isocyanate compound and then treated with an adhesive composed of a mixture of a resorcin-formaldehyde resin and a 2,3-dichlorobutadiene-containing polymer latex, wherein the molar ratio of resorcin to formaldehyde is from 1:0.1 to 1:5, and the solid component weight ratio of the latex to the sum of resorcin and formaldehyde is from 1/100 to 1/1;
- and wherein the liquid mixture of resorcin-formaldehyde resin and polymer latex has a solid component concentration of from 2 to 50% by weight.
