Description

(54) PLASTICS-BASED LAMINATED MATERIAL (71) We FORD MOTOR COMPANY LIM ITED, of Eagle Way, Brentwood, Essex CM13 3BW, a British Company, do hereby declare the invention for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- This invention relates to a laminated material of particular utility in the manufacture of vehicle trim panels.
Automotive trim panels in common use comprise a support, for example of plastics, hardboard or metal, and a decorative surface of paint or of plastics film or cloth secured to the support as by an adhesive or dielectric bonding.
An object of this invention is to provide a material which may be used in the manufacture of trim panels and other products with a reduction in the number of manu facturing steps as compared with the methods quoted above.
The invention provides a method of manufacturing a laminated sheet material, comprising extruding a web from a mixture of a plastics material and an inert particulate filler, the filler forming between 35% and 75O/o by weight of the total and the filler particles having a particle size in the range of 0 5 to 25 microns, applying a textile web to one face of the plastics web while the latter is still in a softened state, pressing the webs together, and cooling the webs to form a self-supporting laminate capable of being moulded by the application of heat and pressure.
The invention will be described in greater detail by way of example, with reference to the accompanying drawing, which is a schematic side view of apparatus for use in carrying out the invention.
Thermoplastic material is extruded from an extruder 10 through an extrusion die 12 to form a web 14. A web 16 of cloth is fed from a reel 18 onto the surface of the web 14 at a position where the latter is still in a softened state. The webs 14, 16 are then passed together through sizing rolls 22, that is hardfaced rolls (e.g. of steel) operating with a predetermined separation in the nip between the rolls, which force the two together while cooling the plastics web 14, to form a laminate in which the cloth is bonded to the plastics web and forms a decorative finish on one side thereof. An infra-red heater 20 may be used to raise the temperature of the plastics web 14 before the cloth is applied, to improve adhesion.In an alternative (not shown), the two webs may be fed first to a heated roll which contacts the plastics web 14 only, and then between sizing rolls; the initial heated roll also improves adhesion.
The cloth suitably has a melting point equal to or greater than the temperature of the extruded web at the point of contact. It is preferably a knitted or woven fabric capable of stretching in one or both directions.
Suitable fabrics are of polyamide 6, polyamide 6 : 6, and cotton.
The extruded plastics material may be a crystalline polymer such as polyethylene, polypropylene (homopolymer or copolymer), or a polyamide, or an amorphous polymer such as an acrylonitrile-butadiene-styrene terpolymer, polyvinyl chloride ar polystyrene.
In accordance with the invention, the extruded material contains an inert filler of particles having a particle size of 0.5 to 25 microns, such as limestone, chalk, glass fibre, mica, or talc, the proportion of filler being between 35% and 75% by weight. The filler acts to hold the plastics material in a controllable sheet form while its temperature is elevated in the region of the extruder and sizing rolls. A mixture of filler and polymer powder may be extruded from a twin screw or planetary screw compounder extruder.
Alternatively, the mixture may be extruded to form granules and subsequently reextruded to form the web 14.
A typical example of the material is polypropylene copolymer filled with 50% to 65% by weight, and preferably 60%, of limestone and bonded to a knitted brushed nylon fabric. The limestone is in the form of particles with a particle size between 1 and 7 microns.
It is also possible to use as the cloth web a sandwich having a laminated foam interlayer, e.g. two layers of polyamide 6 bonded to either side of polyether foam, or a composite cloth/plastics sheet arranged with the cloth adjacent the extruded plastics web, e.g. PVC sheet backed by cloth such as knitted polyamide.
Pieces of the material thus produced may be formed into a shaped product such as a vehicle trim panel in a further operation, by vacuum forming after heating above the crystalline point (or melting point, if amorphous) of the plastics web, or by press forming after heating to a temperature sufficient for forming without splitting of the plastics web.
WHAT WE CLAIM IS: 1. A method of manufacturing a laminated sheet material, comprising extruding a web from a mixture of plastics material and an inert particulate filler, the filler forming between 35% and 75% by weight of the total and the filler particles having a particle size in the range of 0.5 to 25 microns, applying a textile web to one face of the plastics web while the latter is still in a softened state, pressing the webs together, and cooling the webs to form a self-supporting laminate capable of being moulded by the application of heat and pressure.

11. A method according to any preceding claim, in which the textile web is a knitted or woven fabric capable of stretching in one or both directions.
12. A method according to any preceding claim, in which the textile web is of polyamide or cotton.
13. A method according to any preceding claim, in which the textile web comprises two layers of textile material bonded to either sid of a foam sheet.
14. A method according to any of claims 1 to 12, in which the textile web is formed by a cloth-backed plastics sheet.
15. A method of manufacturing a laminated sheet material substantially as herein described with reference to the drawing.
