Definitions

  • a foam can be obtained by foaming the rubber material according to the present embodiment.
  • the rubber material according to the present embodiment by foaming the rubber material, it is possible to obtain a foam having excellent ozone resistance while suppressing shrinkage after foaming.
  • the rubber material according to the present embodiment may be used in various applications without foaming as long as it has a state in which the above-mentioned foam can be obtained when the rubber material is foamed.
  • the sulfur-modified chloroprene polymer has sulfur (bound sulfur, sulfur bonded to the sulfur-modified chloroprene polymer) constituting the sulfur-modified chloroprene polymer.
  • Sulfur constituting a sulfur-modified chloroprene polymer constitutes a sulfur-modified chloroprene polymer by directly or indirectly chemically bonding to a monomer unit of chloroprene.
  • the sulfur-modified chloroprene polymer may have a monosulfide bond and / or a polysulfide bond (for example, S2 to S8 ) constituting the sulfur - modified chloroprene polymer.
  • the method for producing a rubber material according to the present embodiment may include a plasticization step of plasticizing a sulfur-modified chloroprene polymer after the polymerization step. In this case, the Mooney viscosity of the rubber material can be reduced.
  • the sulfur-modified chloroprene polymer and the plasticizer may be mixed, whereby the molecular chain of the sulfur-modified chloroprene polymer can be cleaved.
  • the plasticizer may be added to a post-polymerization polymerization solution containing a sulfur-modified chloroprene polymer (for example, an aqueous emulsified solution after emulsion polymerization).
  • the plasticizer may be added either before or after the removal of the unreacted monomer, and may be added both before and after the removal of the unreacted monomer.
  • Examples of the hydrazide-based foaming agent include p, p'-oxybisbenzenesulfonyl hydrazide, benzenesulfonyl hydrazide, toluenesulfonyl hydrazide, hydrazodicarboxylic amide and the like.
  • Examples of the nitroso-based foaming agent include N, N'-dinitrosopentamethylenetetramine.
  • Examples of the azo-based foaming agent include diazoaminebenzene, azodicarbonamide, azobisisobutyronitrile, barium azodicarboxylate and the like.
  • the content of the foaming agent may be 1 to 20 parts by mass, 3 to 15 parts by mass, or 5 to 10 parts by mass with respect to 100 parts by mass of the rubber material.
  • processing aid examples include fatty acids such as stearic acid; paraffin-based processing aids such as polyethylene (paraffin wax); fatty acid esters; fatty acid amides; sulfur factices and the like.
  • the content of the processing aid may be 0.5 to 5 parts by mass with respect to 100 parts by mass of the rubber material.
  • Example 3 The amount of sulfur used was changed to 0.40 parts by mass, the amount of conjugated resin acid-based potassium rosinate A was changed to 4.30 parts by mass, and the amount of conjugated resin acid-based potassium rosinate B used was 0.
  • a rubber material was obtained by operating in the same manner as in Example 1 except that it was changed to .88 parts by mass.
  • Example 5 The amount of sulfur used was changed to 0.50 parts by mass, the amount of conjugated resin acid-based potassium rosinate A was changed to 4.22 parts by mass, and the amount of conjugated resin acid-based potassium rosinate B used was 0.
  • a rubber material was obtained by operating in the same manner as in Example 1 except that the content was changed to .98 parts by mass.
