Abstract
A laminate 1 has first 3 and second 4 layers in spaced face-to- face relationship and an interlayer 5 adhering to the first and second layers, and at least one of the layers 4 comprises two or more side-by- side sheets. In the figure a double-glazing unit is shown which is made up of two of the laminates 1 spaced from each other in a frame 2. The joins between the sheets making up the layer 4 may be disguised with strips of wood or lead 6 and similar strips may be applied to the single sheet of layer 3 to complete the effect. Referred materials for the sheets include glass, polycarbonate and polymethylmethacrylate. <IMAGE>
Description
SPECIFICATION
A laminate
This invention relates to a laminate.
Laminates of glass and/or translucent plastics material are becoming increasingly widely used as a result of their safety properties, in that they are less likely to fracture on impact than ordinary glass and, if fractured, the glass is held in place, preventing the release of dangerous sharp splinters.
Such laminates are now being used in glass doors, but for doors having a number of small panes it is costly and time-consuming to have to cut or form individual laminated panes and then instal them one by one. Further, such doors cannot be double glazed without increasing the depth of the astrigals, which can detract from the aesthetic effect of the door.
According to the present invention there is provided a laminate having first and second layers in spaced face-to-face relationship, and an interlayer adhering to the first and second layers, at least one of the layers comprising two or more side-by-side sheets.
Further according to the invention there is provided a method of forming a laminate, comprising laying two or more first rigid sheets side-by-side on a planar surface, laying a further rigid sheet over the first rigid sheets in spaced face-to4ade relationship therewith, forming a barrier to passage of liquid around a portion of the periphery of the sheets so that the sheets and barrier form an open envelope, providing the envelope at an inclined angle to the horizontal so that the barrier extends around a lower portion of the envelope, introducing into the envelope through the open upper portion thereof a liquid which on solidifying adheres to the sheet, and solidifying the liquid.
The layers may be for example of glass or other translucent material such as polymethyl methacrylate. The laminate may in that case be used in windows or doors or other areas where passage of light is desired.
The side-by-side sheets may abut one another or may be spaced laterally, for example by means of a spacer which may protrude beyond the thickness of the sheets to provide an astrigal. When the sheets are abutting, their joints may be covered from view by an artificial astrigal in the form of a strip of material, for example wood or lead. In this way a panel for a glass door or window may be made by laminating a number of small panes of glass to a single sheet of glass, and then applying strips of material representing astrigals to one or both faces of the laminate to give the impression of a number of separate panes each held between the astrigals.
The side-by-side sheets may be differently coloured or patterned, and they may be of any desired shape to provide a regular or random arrangement of distinctive sheets.
One or more of the sheets may alternatively be silvered to provide a mirror surface.
The laminate of this invention is especially useful in providing double glazing in a subdivided frame, as both panes can be a single layer extending between side supports, with side-by-side sheets laminated to them. Thus a safety-glass double-glazed unit can be provided for a door or window, and imitation astrigals applied to it if desired.
The laminating method can conveniently be performed by the general methods described in Patent Specifications Nos. 1,600,867 and 2,032,844.
Embodiments of the present invention will now be described by way of example with reference to the accompanying drawings, in which:
Figure 1 is a front view of a double-glazing unit made from laminates of this invention;
Figure 2 is a section on A-A of Fig. 1;
Figures 3(a) to (f) are front views of alternative patterns of glass doors having laminates of this invention.
Referring to Figs. 1 and 2, the doubleglazing unit has a pair of laminates 1 sealed into a peripheral frame 2. Each laminate 1 consists of an outwardly-facing single sheet 3 of glass and three side-by-side inwardly-facing glass sheets 4, with an interlayer 5 of resin between the sheets 3 and 4. The resin is
UVAC 2889 of Warwick International Limited containing y-meth acryloxypropyl-tri methoxysilane as a primer.
Each sheet 4 in each laminate 1 abuts its neighbouring sheet 4, and a strip 6 of lead runs along each joint. Similar strips 6 run across the sheet 3 to disguise the joints between the sheets 4 and to complete the leaded effect.
The laminates 1 are manufactured as follows.
A sheet of board is laid flat and the three sheets 4 of glass are laid on it with their edges abutting. The lead strips 6 are adhered along the joints. The board and sheets are then inverted and laid on a tilting table, with the strips 6 on the lower face. The board is removed and the sheet 3 with the strips 6 in position on its faces is placed on the sheets 4 in face-to-face relationship, with gas-permea ble tapes between the sheets at their periphery to space them apart. The table is then tilted to an angle to the horizontal and the sheets 3, 4 prised apart at their upper edge.
The liquid UVAC 2889 with its silane primer, in admixture with methyl ethyl ketone peroxide catalyst, is then introduced between the sheets through their open top.
The resin is in measured quantity to fill the intersheet space to the required thickness.
The sheets 3, 4 are then closed against the tape at their upper edges to form a liquid
impermeable but gas-permeable barrier
around the sheets, and the sheets are laid flat to allow the resin to spread through the entire
intersheet space, expelling air through the tape. The resin is then allowed to cure, pro
ducing the laminate.
Figs. 3(a) to o) show different arrangements of sheets in laminates in use in glass doors.
The areas marked "8" are sheets of bronzecoloured glass, and those marked "C" are clear sheets in side-by-side relationship to the bronze sheets. in Figs. 3(a) to (e) the bronze and clear sheets in each case are laminated to a single sheet of clear glass, whereas in Fig.
3(f) the laminate has a first layer formed by two clear triangular sheets 7 having a bronze
diagonal sheet 8 between them in side-by-side relationship, this layer being laminated to a second layer which is similarly made up, with the diagonal bronze sheet 8(a) in that case
running between the opposite corners of the
laminate than in the first layer. Thus the central diamond-shaped area 9 appears a darker bronze colour than the remainder of the diagonal sheets 8, as the colour is of double intensity.
Generally the laminates of this invention can provide safety glazing so long as joints between sheets in the first layer do not run in the same position and direction as joints between sheets in the second layer.
Modifications and improvements may be made without departing from the scope of the invention.
