Description
PRODUCTION Qg COMPOSITE LIGHT-TBANS ITTIHG MATERIAL This invention relates to the production of composite light-transmitting material incorporating a coating which significantly influences the optical or thermal properties of the composite material.
It is known to make composite glazing material having special optical or thermal properties which are conferred by one or more thin transparent coatings applied to a sheet of glass. For example, radiant heat-reflecting glazings are used in blast furnace plant and elsewhere, comprising a sheet of glass bearing a thin metallic coating which has good radiant heat-reflecting properties and is protected by another sheet of glass to which the coated sheet is united by means of a sheet of plastics material. Such glazings are fairly simple to produce if the sheet of glass on which the optical coating is formed is small and flat. If either of these two conditions does not apply then problems arise in forming an optical coating, of the necessary uniform thickness, in mass production manufacture.
The present invention provides an alternative process which enables composite glazing panels with optical coatings to be manufactured quite easily regardless of the dimensions of the panels and regardless of whether they are flat or curved.
According to the invention a composite light-transmitting material comprising at least one sheet of glass and at least one light-transmitting coating which significantly influences the optical or thermal properties of the composite material is produced by a method wherein a said ooating is formed on a light-transmitting plastics sheet material and the plastics material bearing said coating is secured directly or indirectly to a sheet of glass to form a laminate.
In preferred embodiments of the invention a light transmitting coating which significant]^ influences the optical or thermal properties of the composite material is formed on a light-transmitting plastics sheet material which is sufficiently flexible to be easily coilable. In the manufacture of composite glazings using coilable plastics sheet the latter can be unwound and conveyed continuously in or through a coating installation. Optical coatings are normally and preferably formed by deposition in vacuo. When adopting such a coating method, coiled plastics sheet can be unwound and conveyed continuously in or through the evacuated enclosure in which the coating substance is vapourised and the vacuum can be maintained without interruption. The coated plastics sheet can be subsequently out into pieces of any required size according to the sizes of the glazing panels to be produced. This represents a great advantage over the established practioe of coating the glass. The coating of large sheets of glass requires correspondingly large coating installations. If glass sheets of a variety of different sizes have to be coated in a given factory it is necessary to provide a number of coating installations of different sizes and there is a waste of production capacity whenever a given coater is used for coating sheets smaller than the maximum size for which it is designed. In the case of vacuum coating installations there is the added complication of re-establishing the vacuum each time a fresh sheet is introduced into the vacuum chamber and the waste of capacity involves an important financial loss.
The coated coilable plastics sheet, due to its regardless of whether this is flat or curved.
It is not essential however for the plastics sheet material to be so thin and flexible that it can be coiled. A substantially rigid plastics sheet can be moulded to a given shape much more easily than a sheet of glass and when producing a composite curved glazing panel, e.g. , a vehicle windscreen, it is therefore of considerable advantage to form an optical coating on a flat sheet of plastics and simultaneously or subsequently to unite the coated plastics sheet with the shaped glass panel. The advantage of this procedure over the known procedure of optically coating the curved glass sheet is considerable. It is very difficult to form a thin coating of uniform thickness on a curved surface, particularly by chemical coating methods. Moreover when coating curved glass sheets they have normally to be held by specially shaped supports or moulds which further militate against efficient utilisation of the coating installations.
The invention is particularly but not exclusively concerned with the production of heat-reflecting glazing materials incorporating optical coatings of a metal or metal compound.
In general, such coatings adhere more strongly to plastics than to glass.
A composite . glazing material produced according to the invention may incorporate more than one optical coating for modifying the light-transmitting and/or radiant heat reflecting properties. If there is more than one such coating there may be two coatings on one plastics sheet, or two or more plastics sheets each bearing a coating on one or each side may be present, A glazing material produced according to the invention may In addition to the one or more sheets of glass and the one or more coated plastics sheets, a glazing material produced according to the invention ma incorporate one or more other layers or sheets, e.g., a bonding layer or sheet, which latter may be an uncoated sheet of a suitable plastics. Thus, to outline certain possibilities, a coated plastics sheet may be bonded to a sheet of glass, with, the coated or uncoated side of the plastics sheet facing the glass, by means of a layer of adhesive applied to the coated plastics sheet or to the glass, or by means of a sheet of adhesive plastics. The expression "adhesive plastics" here denotes a plastics which is permanently adhesive or a plastics which is an activatable adhesive, e.g., a pressure- or heat-activatable adhesive.
Particularly when using thin coilable plastics material for bearing the optical coating or coatings, it is preferable for the or eaph sheet of such material to be disposed between two sheets of glass, or between a sheet of glass and a sheet of plastics which is rigid or substantially more rigid than the plastics sheet material bearing the optical coating or coatings.
The following plastics may, e.g., be used in sheet form for bearing an optical coating in a glazing produced in accordance 'with the invention': polyesters, polyarylesters, polyamides, ionomer resins, polytrifluorochloroethylene, polytetrafluoethylene fluorohalocarbon polymer, cellulose triacetate.
The following are examples of substances which can form an optical coating in a glazing produced in accordance with the invention: gold, silver, metal oxides, e.g., Sn02 and TiC^, and organo-metallic compounds.
In various advantageous embodiments of the invention, as will hereafter be exempli ied, a sheet of uncoated plastics material is incorporated between a plastics sheet bearing an optical coating on the one hand and a more rigid sheet composed of glass or plastics on the other hand. The following are examples of materials which may be used for such an interpolated 'sheet: regenerated cellulose (cellophane), polyvinylbutyral, vinylidene chloride-vinyl chloride copolymer.
The invention includes composite glazing material comprising at least one sheet of glass, at least one light-transmitting plastics sheet and at least one light-transmitting coating which significantly influences the optical or thermal properties of the composite material and which has been formed on a said plastics sheet prior to its incorporation in the glazing material.
A composite material according to the invention may be incorporated in a double glazing unit.
Various embodiments of the invention will now be described with reference to the accompanying drawings comprising Pigs. 1 to 6 which are cross-sections of six different materials according to the invention.
The flat composite glazing shown in Fig. 1 comprises a sheet of glass 1, and a sheet 2 of polyvinyl chloride. Between these sheets there are a sheet of adhesive plastics material 3 and a sheet of plastics material bearing a thin coating 5 which significantly influences the optical properties of the composite glazing. The sheet of adhesive plastics material 3 is a sheet of polyvinylbutyral; the sheet of plastics material is a flexible sheet of polyamide bearing as the thin layer 5 a layer of gold. Such gold layer may, e. g. , be formed on the sheet 4 by vapourisation in vacuo.
The constituent elements of the glazing may be assembled by locating them face to face in the illustrated order and then heating the assembly, while it is under pressure, in an autoclave as known per se in the production of sandwich glazings. When subjected to a low pressure (about 4 kg/cm^) and to a temperature below 150°C, the constituent 3heets become secured together inside the autoclave, due to partial melting of the polyvinyl-butyral sheet 3 · The glazing shown in Fig. 2 comprises a sheet 6 of glass and a sheet 7 of polymethylmethacrylate. Between these sheets there are a flexible sheet 8 of polytetrafluoroethylene bearing a thin layer 9 of SnOg, and a sheet 10 of polyvinylbutyral.
The constituent elements of the glazing material shown in Pig. 2 can be caused to be bonded together in the same way as the elements of the material shown in Fig. 1, as above described.
The material according to Fig. 3 comprises two sheets of glass 11, 12. Between these glass sheets there are two sheets 13 , 1 of polyvinylbutyrul and, between these adhesive plastics sheets there is a sheet 15 of diallyl isophthalate bearing thin coatings 16, 1? of gold on its two surfaces.
Fig. shows a composite glazing which is curved, as often required in the manufacture of vehicle windscreens. The glazing comprises two external sheets 18, 19 of glass. At the inner sides of these sheets there are two sheets 20 , 21 of polyvinylbutyral. Between the sheets 20, 21 there is a sheet 22 of fluorohalocarbon polymer bearing a thin gold coating 23 on its convex side.
The glazings shown in Figs. 3 and 4 can be caused to adhere together by a known process, e.g., by a process as above described in connection with Fig. 1.
The glued composite glazing shown in Fig. 5 comprises two flat outside glass sheets 21+, 25 between which there is a polyester sheet 26 bearing on one of its surfaces a thin- coatin 27 of T1O2. The assembled sheets were glued together by placing than on a horizontal conveyor of a kind known per se and comprising rubber laminating rollers and heating means at regular intervals along the path of the sheet assembly. The sheets were in that way heated to a temperature below 190°C, and progressively subjected to pressure up to a value of about 6 kg/an . The sheet 26 of polyester became softened enough to enable the occluded air to escape and to allow the bonding to take place, but the softening did not disturb the required homogeneity and continuity of the thin coating 27.
Fig. 6 shows another glued composite glazing panel comprising a sheet of glass 28 and a polyester sheet 2 which latter bears on one of its surfaces a thin coating 30 of T1O2.
The sheets have been glued together by heating them to a temperature below 180°C and subjecting them to a pressure of 2 6 kg cm in an autoclave. In this treatment, the polyester sheet 29 became softened enough to enable the occluded air to escape and to cause the sheets to adhere. The softening of the polyester sheet had no adverse effect on the homogeneity and continuity of the TiOg coating 30. After thus uniting the sheets the composite .panel was incorporated in a double glazing unit as shown. This unit was formed in the following manner : Spacing members 31 of rectangular section were disposed on the periphery of the polyester sheet 29 , and a sheet of glass 3 was then placed on such spacer members. he margins of the composite glazing panel and of the glass sheet 32 were then enclosed in the inwardly opening channel of a metal frame 33 the frame members being secured together at the frame corners by welding.
It will be understood that any of the various illustrated ways of ordering the different constituent layers or sheets of a composite glazing material according to the invention can be adopted, using layers or sheets of materials other than those employed in the actual illustrated products.
