Definitions

  • Water leaching may and usually is employed as part of the procedure to remove rubber impurities.
  • the methods and materials of glove manufacture are also described, for instance, in
  • Halogenation e.g. chlorination
  • other chemical surface treatments have been used to eliminate the need for a powder coat on the final product to enable dry donning. While effective, this step is expensive and has the shortcoming of reducing shelf life of the rubber article. It would be desirable to provide a rubber article with a powder-free donning surface without resorting to the expensive and article deteriorating practices now in vogue. This could substantially reduce the cost of manufacture and maximize the shelf life of the rubber article.
  • U.S. Patent 4,304,008 applies a covalently bonded silicone or urethane to the outer surface of the glove and halogenates the inner surface.
  • the halogenated inner surface eliminates the need for a donning powder.
  • U.S. Patent 4,310,928, also to Joung and incorporated herein by reference teaches the deposition of a lipo compound (lipid or lipophilic substances) in place of a powder of mineral origin in combination with a surfactant in a coagulant solution to form a uniform film on a glove mold onto which the rubber is coagulated.
  • the lipo compound and surfactant enable stripping of a formed glove from its mold.
  • the acrylic based copolymers are preferably emulsion based copolymers of at least one reactive low surface energy monomer, preferably a silicone oligomer, at least one alkyl acrylate and at least one reactive hard monomer, the total of hard monomers being present in an amount sufficient to form a non-tacky copolymer directly or by blending of copolymers.
  • the copolymers exhibited at least one dominant glass transition temperature (Tg) peak above O°C and typically at least one dominant glass transition temperature peak below about O°C.
  • Tg dominant glass transition temperature
  • One effective glass transition temperature is generally above about 15°C, preferably from about 15 to about 60°C. It is presently preferred that at least the donning surface be formed by sequential polymerization of two monomer systems; one providing the dominant low glass transition temperature peak, the other providing the dominant high glass transition temperature peak.
  • the coagulant may be deposited on the acrylic based copolymer or deposited therewith from suspension.
  • the object is to provide a surface concentration of coagulant salt which will enable coagulation of the latex onto the deposited copolymer coat in a commercially acceptable time.
  • the preferred coagulant salt is calcium nitrate and is used in a concentration up to about 40, preferably from about 20 to about 40 percent by weight of the suspension.
  • the mold having a coagulant and polymer coated surface is immersed into a rubber emulsion or latex from which the rubber deposits and coagulates on the surface of the copolymer forming a coated interior glove surface.
  • the formed rubber article is dried, cured, then immersed into an aqueous suspension of the same or a different acrylic based copolymer which exhibits good donning characteristics. Dipping forms a donning polymer coat on the exterior of the rubber glove.
  • the formed coated glove is then stripped from the mold. This reverses the glove placing the donning coat on the interior of the glove.
  • water leaching may be effectively employed for rubber purification.
  • the preferred mold is a contoured mold.
  • molds having a textured to highly polished ceramic or porcelain surface and molds having a fluorocarbon coating may be employed, it is preferred to employ a mold which is sufficiently textured to produce a dull finish in the deposited laminate formed by depositing the rubber from the latex onto the copolymer coating. This is achieved by roughening the mold surface by blasting with sand or glass beads. The surfaces used have been measured to have a roughness of from about 8 to 10 microns peak to valley.
  • FIG. 1 is a flow diagram of the current method of rubber glove manufacture
  • the monomers are also selected to provide sufficient elongation so that the acrylic based copolymer coating will stretch or elongate with the rubber with minimal cracking, flaking or debonding.
  • Suitable copolymers have an elongation of 100 to 500% or more, typically from about 100 to about 300% when self bonded to a rubber surface.
  • the articles and surgeons which have the most critical requirements are examination and surgeons gloves. Because of their complex shape, they must be capable of being stripped from a mold using commercially acceptable practices and yet provide, a surface, which when stripped from the mold, has good tactile feel; that is, the ability of a person to pick up articles with a good grip. In this regard, good tactile feel is contra to good mold stripping.
  • One class of the monomers used in forming the copolymers are alkyl acrylate monomers containing from 1 to about 10 carbon atoms in the alkyl group, present in a total amount of from about 30 to about 85% by weight of the monomers, preferably from about
  • the alkyl acrylate monomers that may be used include methyl acrylate, ethyl acrylate, butyl acrylate, propyl acrylate, 2-ethylhexyl acrylate, isooctyl acrylate, isodecyl acrylate, and the like.
  • the presently preferred alkyl acrylate monomers are butyl acrylate and methyl acrylate.
  • FIG. 3 is a glass transition temperature plot for a good donning copolymer coating where relative peak intensities of glass transition temperature are reversed.
  • weight ratio of the soft or low glass transition temperature copolymer to high glass transition temperature copolymer be in the range of about 1: 1 , to about 1:3, preferably about 1 to 1.5.
  • the suspension formed from the emulsion copolymer tolerate electrolytes typically employed for latex coagulation in concentration typically used for latex coagulation, i.e., in the range of about 3 to about 10% by weight of suspension.
  • the presently preferred surfactant system is a combination of anionic surfactants.
  • One of the anionic surfactants has a molecular formula C 2O H 37 0 7 NaS and containing 20 mols of ethylene oxide and is used in admixture with anionic surfactants which are salts of sulfated nonyl phenoxypoly (ethyleneoxy) ethanol and sodium lauryl ether sulfate.
  • Vinyl-addition silicone systems react by thermally induced addition-cure (hydrosilation) between polydimethyl-hydrogen siloxane crosslinkers and reactive vinyl-functional silicone polymers to furnish a cured polymer.
  • a coagulant salt is required to cause the rubber to deposit from its emulsion (latex) onto a surface of the polymer.
  • the coagulant may be applied after drying of the copolymer on the surface of the mold, a considerable savings in time and cost can be realized by combining a coagulant with the copolymer suspension. It has surprisingly been found that the copolymer suspensions of the instant invention can tolerate the high amount of polyvalent O 96/25278 PCMJS96/01866
  • the presently preferred molds are smooth contoured molds having a textured, or smooth ceramic, porcelain or a fluorocarbon surface which will accept the coating of the copolymer or the copolymer and coagulant and release the formed rubber article at the completion of the process.
  • the amount of time of immersion in the rubber emulsion determines the thickness of the formed rubber coat.
  • a typical thickness is from about 6 to about 10 mils.
  • FIG. 3 shows the DSC profile for the copolymer with major glass transitive temperature peaks at -21.04°C, 11.74°C + 12.45 and -l-28.55 c C. Surface morphology revealed a slightly irregular continuous surface with microcraters and submicron protrusions, the microcrater diameters ranging from 0.1 to 1 ⁇ .
  • FIG. 4 shows the DSC plot for this polymer and the several glass transition peaks, the major ones being at -12.51 °C, 13.57°C and 29.76°C.
  • the second monomer charge there was employed a monomer mix of 348 parts styrene, 136.6 parts butyl acrylate, 9 parts methylacrylic acid, 248 parts acrylic acid, 30.8 parts RC 726, 8.7 parts N-isobutoxymethyl acrylamide, the incremental catalyst solution contained 70.5 parts deionized water, and 2.5 parts of potassium persulfate. There was formed by sequential emulation polymerization emulsion of the copolymers which a total solid content of 53.3. The formed copolymers provided aggressive protective coatings for rubber surfaces.
