Definitions

  • the invention relates to the field of bullet resistant laminated glazing. Background of the Invention
  • Bullet resistant glazing provides resistance to penetration by projectiles (bullets).
  • a laminated comprised of combinations of various types of glass and plastics are utilized to absorb and dissipate the energy of the projectile, preventing penetration and protecting the occupants of the vehicle from the projectile and any spalling of the glass.
  • BRG commonly includes chemically tempered and heat strengthened glass layers.
  • the glass layers may comprise various glass compositions such as borosilicate and aluminosilicate, in addition to soda-lime, as well as glass that has been thermally or chemically strengthened.
  • Rigid plastic non-bonding layers comprising but not limited to polyurethane, acrylic and polycarbonate are also sometimes used.
  • thermo-plastic interlayer In a conventional laminated non-bullet resistant glazing, two layers of annealed soda-lime glass are bonded together by a thin sheet of thermo-plastic interlayer. This provides for improved occupant retention in the event of an accident and resistant to penetration by low energy projectiles, such as small stones, but will not stop bullets.
  • BRG laminates make use of combinations of various types of glass and rigid plastics to absorb and dissipate the energy of a projectile, prevent penetration and protect the occupants of the vehicle from the projectile and any spalling of the glass.
  • the selection of materials, number of layers and thicknesses are dependent upon the level of threat that the glazing is designed to withstand. Threat levels are defined by international standards in terms of the type of projectile that the glazing must be able to stop. For a minimal small caliber projectile, a thickness of 19 mm with up to five layers of glass and plastic, not counting the bonding layers may be required. To stop large caliber military grade projectiles, the total thickness may go as high at 150 mm or even greater with multiple glass and plastic layers.
  • the plastic bonding layer has the primary function of bonding the major faces of adjacent layers to each other.
  • the most commonly used bonding layer or interlayer is polyvinyl butyl (PVB).
  • PVB polyvinyl butyl
  • ionoplast polymers ethylene vinyl acetate (EVA), cast in place (CIP) liquid resin and thermoplastic polyurethane (TPU) can also be used.
  • Interlayers are also available with enhanced capabilities such as solar control and sound dampening.
  • the types of glass that may be used include but are not limited to: the common soda-lime variety typical of automotive glazing as well as aluminosilicate, lithium aluminosilicate, borosilicate, glass ceramics, and the various other inorganic solid amorphous compositions which undergo a glass transition and are classified as glass included those that are not transparent.
  • the glass layers may be comprised of heat absorbing glass compositions as well as infrared reflecting and other types of coatings.
  • the rigid plastic non-bonding layers are typically comprised of but not limited to polyurethane, acrylic and polycarbonate.
  • the glass layers may be annealed or strengthened.
  • thermal strengthening in which the hot glass is rapidly cooled (quenched)
  • chemical tempering which achieves the same effect through an ion exchange chemical treatment.
  • ions in and near the outside surface of the glass are exchanged with ions that are larger. This places the outer layer of glass in compression. Compressive strengths of up to 1, 000 Mpa are possible.
  • Compressive strengths of up to 1, 000 Mpa are possible.
  • One of the major problems in the industry is the cost to produce such laminates.
  • BRG glazing is labor intense to produce. Small parts are even more of a problem as the labor required to produce a small part can be just as much as required to produce a much larger part.
  • TPU film is one material that is commonly used as an edge seal.
  • TPU does not a good job of blocking water.
  • the primers and adhesives that are used to install the glass in the vehicle tend to attack TPU. These chemicals can react with the TPU and the laminate layers resulting in yellowing and delamination.
  • Other means that have been used include: synthetic resin such as fluoropolymer, polybutene polymer or butylpolymer, an ethylene-polymer-in-water, copolymers composed of isobutene units and at least two further polymer blocks that are composed of units derived from vinylaromatic monomers, a waterproof silicone adhesive, a hot-melt resin adhesive and an adhesive comprised of acrylate or metacrylate homopolymers or copolymers or mixtures thereof.
  • synthetic resin such as fluoropolymer, polybutene polymer or butylpolymer, an ethylene-polymer-in-water, copolymers composed of isobutene units and at least two further polymer blocks that are composed of units derived from vinylaromatic monomers, a waterproof silicone adhesive, a hot-melt resin adhesive and an adhesive comprised of acrylate or metacrylate homopolymers or copolymers or mixtures thereof.
  • a large laminate panel is fabricated and then the individual smaller laminates are cut by means of an abrasive water jet from the larger panel. After any required edge work, cleaning and priming (3M 94-3M), the laminate edge is sealed through application of a sealing film. For additional strength, adhesion promoters may also be used in addition to the primer.
  • the pressure sensitive sealing film (3M 441 IB) is comprised of a tough, flexible, abrasion resistant thin sheet of a water proof monomer coated with a thick layer of a soft, weather resistant, high tack, acrylic adhesive.
  • a release layer is applied over the adhesive to aid in installation and to allow dispensing and storage on a roll.
  • the adhesive has excellent adhesion to the glass and plastics used to make BRG laminates and to the monomer itself so that the film can be overlapped and still achieve a good seal.
  • the film is cut to length from a roll in the case of a rectangular seal or cut from a sheet.
  • the release backing is removed as the seal is applied.
  • a roller, squeegee or other smoothing means is used to force out any trapped air between the glazing and the seal and to ensure good contact between the adhesive and the glazing. An overlap of about 6 mm is sufficient to bond the seal to itself. No further processing is required.

Abstract

La production d'un vitrage résistant aux balles (BRG) tend à nécessiter beaucoup de main-d'œuvre par rapport à un vitrage non BRG typique. De nombreuses étapes sont nécessaires pour assembler et stratifier les multiples couches requises et les volumes produits tendent également à être faibles. La production de grands stratifiés puis la découpe de pièces de petites à moyennes dimensions à partir de la feuille plus grande et l'utilisation d'un procédé d'étanchéité à bord froid permettent de réduire considérablement la main-d'œuvre et de fortement accroître la cadence de production.
