Definitions

  • the invention relates to an improved material suitable for preparing decorative interior trim for protecting door panels, instrument panels and finishes around the perimeter of openings for doors and the like in automotive and other vehicles or compartments.
  • Automobiles and other vehicles usually include finished, upholstered passenger compartments having door and other openings to the exterior.
  • the perimeters of the openings present an interface between the interior and the exterior materials that is exposed to contact by people and objects passing in or out of the compartment.
  • this perimeter area has been protected by sewn leather, molded rubber and/or fabric bumpers or guards.
  • molded plastic parts have been provided that are fastened to conceal the interface between the interior and exterior materials.
  • these parts are made by adhering a suitable decorative laminate to a molded structural profile that permits attachment.
  • a laminate of this type comprises a polyolefin film backing and an embossed vinyl decorative face. While suitably durable and attractive for most uses and for many different environments, failures are not uncommon in use due to negative interactions with ingredients from the underlying materials combined with UN exposure, thermal cycling, heat aging and the like.

  • the facing sheet material is formed onto a suitable backing by contacting a thermosetting polymer by contact with an embossed, pealable sheet.
  • the decorative facing sheet material eliminates PNC and its associated problems of plasticizer migration and brittleness.
  • the materials of the invention will be recyclable and lighter than PNC.
  • the term "interior trim” is meant to include contoured members made of one or more plastic materials, some with embedded metal reinforcements, designed to be fixed to a vehicle interior, such as an opening in an automobile door.
  • the interior trim will protect an interface between a metal structure and a decorative covering typical of interior trim.
  • the term also relates to other interior applications like small electronic devices copying interior and exterior automotive finishes.
  • the facing sheet material is formed onto a suitable backing by contacting a thermosetting polymer by contact with an embossed, pealable sheet.
  • the decorative facing sheet material eliminates PNC and its associated problems of plasticizer migration and brittleness.
  • the materials of the invention will be recyclable and lighter than PNC.
  • FIG. 1 is a schematic, cross-sectional view of a molded structural door trim profile of the invention including a decorative facing sheet material formed in accord with the invention.
  • the door trim profile is comprised of a decorative facing material 10 affixed to a molded structural member 11.
  • the specific shape of structure 11 will be determined by the particular application intended and will complement the particular structure to which it will be attached.
  • Various flanges, e.g., 11a, bumpers, e.g., l ib, and the like are provided for attachment, cushioning and/or decoration.
  • FIG. 2 is a schematic cross section of a decorative facing sheet material 10 formed in accord with the invention.
  • Sheet material 10 is shown comprised of three layers.
  • a first layer 12 is a embossed paper or other material used to impart a pattern to the outer surface of an outer decorative layer 16 which is revealed when layer 12 is stripped from layer 16 as will be described later.
  • Embossed papers of this type can impart any desired surface configuration to the final decorative material, including a leather or fabric appearance among many.
  • Layer 14 is of a suitable backing material such as a polyolefin film, e.g., coextruded trilaminate of polyethylene of 5 mil thickness.
  • the film is preferably of a type that has been oriented and surface treated, such as by corona discharge. Other materials, can also be employed.
  • Intermediate layer 16 of a cast polyester will be the outer surface of the finished article and is of a material capable of withstanding the physical stresses necessary for this purpose. It will have imparted to it a surface configuration complementary with that of the first layer.
  • other curable casting resins can be employed, e.g., polyurethanes, polyurethane polyesters, and the like.
  • the preferred materials are solvent-based. The materials are selected based on their ability to be shaped in the manner described, their durability to abrasion and ultraviolet light, ability to be color matched, processability, stain resistance and resistance to delamination.
  • FIG 3 is schematic cross section of one embodiment of the invention for forming the decorative facing sheet material illustrated in Figure 2.
  • a decorative facing layer 10 still has paper on is continuously formed by casting a suitable resin onto a backing substrate 14 fed between rolls 22 and 28'.
  • the paper will preferably be removed prior to attaching the decorative facing sheet to a substrate, such as shown in Figure 1.
  • the coated backing is then passed through a suitable drying oven, when necessary as in the case of solvent-based coatings.

  • the polyester 26 in liquid form is of the type typically employed for durable, decorative coatings and can be applied by nip fed reverse roll coating apparatus 28, 28', or the like to a suitable thickness to achieve the desired surface shape. Conveyor rolls 29 can be utilized as needed.
  • the web 12 is pressed against the cast layer 16 and the cast layer against the backing 14,' by passing the three layers between pressure rollers 30 and 32, which may be heated or unheated as required.
  • the lower roller 32 in contact with the backing 14 is chrome-plated and heated to about 200°F, and the upper roller 30 is made of rubber.
  • the combined layers have a thickness suitable for the intended use.
  • Figures 4 and 5 show a variation of the embodiment illustrated in Figures 2 and 3 above, wherein an adhesive layer 118 is applied to a backing layer 114 prior to application of the polyester layer 116 and subsequent laying of the web layer 112 thereon.

It will be noted that the arrangement of Figure 7 is essentially the same as that of Figure 3, but with the layers reversed. As a last step in this procedure, resulting three layer composite is fed through the nip between rollers 230 and 232, where 230 is rubber and 232 is a heated metal roller.
  • Figures 8, 9a and 9b show a variation of the embodiment illustrated in Figures 6 and 7 above, wherein an adhesive or primer layer 318 is applied to the backing layer 314 prior to application of the polyester layer 316 and subsequent laying of the web layer 312 thereon.

Abstract

L'invention porte sur la préparation d'un matériau (10) protecteur et décoratif pour garnitures intérieures (10) offrant une très bonne finition des détails ainsi qu'une intégrité structurelle, et se présentant sous forme d'un profilé moulé de garniture. A cet effet, on forme un composite stratifié (10) sur un substrat (14) de polyoléfine, puis une surface texturée et une bande de papier (12) texturant, puis on retire la bande de papier (12) pour révéler la surface texturée. Le composite (10) peut être fixé par contact à un profilé extrudé de garniture de porte ou à d'autres pièces dans une matrice de formage par extrusion et par passage dans un tunnel de durcissement après l'extrusion, ou par tout autre moyen adéquate. La bande de papier (12) est retirée de préférence avant la fixation au profilé extrudé de garniture de porte. Dans une exécution, le matériau en feuille à face décorative (10) est formé sur un substrat idoine (14) en mettant en contact un polymère thermodurcissable avec une feuille (16) estampée pelable. Le matériau en feuille à face décorative (10) élimine le PVC et ses problèmes associés de migration des plastifiants et de fragilité. De plus, les matériaux de l'invention sont recyclables et plus légers que le PVC.
