Definitions

  • This invention relates to a pressure sensitive composite material and more particularly to a flame retardant, printable, solvent, fuels and lubricating fluids resistant, material for use at elevated temperatures.
  • the material of the present invention is adapted particularly for use in aircraft and ships as an identification tape/label in various applications such as electrical wiring identification, hydraulic line identification, etc.
  • the tape/label is usually wrapped around electrical wire bundles or hydraulic lines which may be exposed to hydraulic line fluids, oils, greases, fuels, and the like.
  • tape/label materials must be able to meet high performance standards under different environmental conditions.
  • a tape or label material must be flame retardant so that it is self-extinguishing when flame is removed from it.
  • the material must also be pressure sensitive and self-adhesive as well as having good adhesive properties to other materials.
  • such material must be capable of reliable service up to 260°C while being solvent, fuels and lubricating fluids resistant.
  • the material Upon meeting all of these requirements, the material must also be capable of being printed upon by impact and laser marking machines. All of these requirements must be contained in a material which in many instances is no more than 1 mm thick.
  • the prior art has attempted to meet the needs of the industry with the use of polyvinylfluorides, polytetrafluoroethylenes and polyimide materials.
  • these prior art materials in various forms do not meet all the high performance standards as set forth above and as required by the industry.
  • most of the prior art materials are not capable of use up to 260°C. Many of them are not flame-retardant because they are combustible after the flame has been removed.
  • the prior art materials are not solvent fuels and lubricating fuels resistant.
  • the materials that have been used in the prior art are not capable of being printed upon by impact or non-impact printing methods such as laser marking machines and the like.
  • one of the objects of the present invention is to provide a new and improved pressure sensitive composite material for use under particular environmental conditons.
  • Another object of the present invention is to provide a new and improved pressure sensitive composite material for use in temperatures up to 260°C, at which temperatures the material is solvent, fuels and lubricating fluids resistant, non-flagging and flame retardant, while at the same time being printdable by impact and non-impact printing methods.
  • the product, 10, of the instant invention is composed of three principal components, a substrate 12, an adhesive coating 14 and a resin coating 16.
  • the substrate 12 is usually of thicknesses less than 1 mm and preferably in the range of .025 mm to about .25 mm
  • This substrate is made up of a, non-woven polyamide, however a non-woven fiberglass mat may also be used as the substrate material.
  • the adhesive coating or layer 14 is placed on one side of the substrate.
  • This adhesive layer must be capable of performing under the extreme conditions of high temperature and still be solvent, fuels and lubricating fluids resistant.
  • the adhesive coating layer 14 will be a polyacrylate and it will be applied to one side of the substrate 12.
  • polysiloxanes, polyurethanes and resin modified natural and synthetic rubbers can be used.
  • the resin modified natural and synthetic rubbers are carefully chosen so that they have the desired adhesive properties, but they are principally chosen from the group consisting of the styrene-butadiene polymers, polyisoprene, polychloroprene and butadiene-acrylonitrile polymers.
  • the adhesive coating is applied to one side of the substrate by appropriate coating methods and apparatus and they may be applied separately or simultaneously with the resin coating 16 which is put on the other side of the substrate material 12. (that is the side opposite the adhesive coating side).
  • the resin coating 16 must be compatible with the substrate material and the adhesive layer while being capable of meeting the stringent, high performance requirements in service, that it be solvent, fluids and lubricating fluids resistant, capable of service up to 260°C in relatively thin sections, of below 1 mm in thickness, and at the same time be capable of being printed upon by impact and laser printing methods.
  • This resin coating 16 is chosen from the polyacrylates, polyesters, polyurethanes and butadiene-acrylonitrile polymers.
  • the resin can also be chosen from solvent resistant resins such as polychloroprene and the chlorosulfonated-polyethylenes.
  • the thickness of the adhesive coating 14 is preferably between .01 mm to about .10 mm while the resin coating 16, preferably ranges in thickness from about .001 mm to about .075 mm.
  • the adhesives chosen for use as the adhesive coating may be partially cross-linked by appropriate chemical and/or ionizing radiation cross linking techniques.
  • the resins that are chosen for use as the top coating can be either the curable types of resin or the non-curable types. A blending of curable and non-curable resins may be used to obtain the optimum balance of properties. In any event, the curable resins may be partially cross-linked either chemically or by ionizing radiation.
  • Release liner material 18 is calendered paper and the like and is applied to the adhesive coating layer 14 thus facilitating the peel off of the composite material 10 when it is manufactured in sheet and roll form.
  • the release liner can be of considerable thickness compared to the composite material 10.
  • the resin 16 can be provided with an appropriate color pigment which will be compatible with the resin coating chosen for the particular use. In any event, it is the product 10 composed of the substrate 12, the adhesive coating 14 and the resin coating 16, which results in the unique properties of the composite material.
  • a .05 mm polyamide paper Nomex Aramid Paper Type 410 was coated on one side with solution "A” using an applicator roller and doctoring off excess with wire-wound Meyer Rod.
  • the coated polyamide paper was dried in a conventional air circulating oven. The coating of the resin was .01 mm when dry. The polyamide paper was then coated on the other side with a polyacrylate adhesive (H & N Chemical Company's Polyad 130). The adhesive was applied with a reverse roll coater and deposited at 0.04 mm dry thickness. The adhesive was dried and cured and the completed composite was then wound up against a 60# silicone coated release paper.
  • a polyacrylate adhesive H & N Chemical Company's Polyad 130
  • Example #2 was prepared in the same manner as example #1 except that the resin solution B was used.
  • the dry thickness for both the resin and adhesive were the same asin example #1.
  • Example #3 was prepared in the same manner as example #1 except a .075 mm Nomex polyamide paper was used and Solution C was used.
