Abstract
A building tile or like building product is formed from a mix 9 of an aggregate compound such as silica sand or crushed stone with a synthetic resin such as a polyester, epoxy, or phenolic. The mix 9 is placed in a mould 10 formed by applying a settable material to the surface of a natural stone tile or block, with a release agent applied to the mood surface. The mix is allowed to cure partially to a gel and is then freed from the mould and the cure completed so as to cause monomer or solvent to be driven off to provide a matt finish which combines with the moulded surface to resemble a natural stone appearance. <IMAGE>
Description
Fabricated Building Products
This invention relates to the manufacture of artificial products for building, decorative purposes, or the like, having the appearance of natural stone, slate or similar material.
Natural stone and slate when cut and shaped for building purposes are in general extremely expensive} partly due to the normal methods of production. Existing artificial alternatives, which'usually involve the use of cement, do not provide top quality performance and appearance and in particular they tend to lack the texture, colour and natural random appearance of stone or slate.
Accordingly, it is an object of the invention to provide an improved building material or products which will better satisfy the commercial needs. In particular the invention aims to provide a building product with an appearance close to natural stone or slate, having in particular the dull matt appearance and random surface details which normally occur in natural stone. The invention also aims to provide such building products in a range of different shapes and sizes, and if required to the same thickness available with natural materials such as slate.
Surprisingly it has been found that by careful selection of the materials used and the moulding or casting conditions improved building products can be obtained to satisfy these requirements.
Broadly stated the invention consists in a moulded building product comprising an aggregate compound or filler with a synthetic plastic resin having a combination of a moulded irregular surface with a matt finish. According to a preferred feature of the invention the initial mixture includes a solvent or monomer which later evaporates from the surface to leave a matt finish.
The particular choice of synthetic resin is important and the resin is preferably polyester, methacrylate, epoxy, urethane, phenolic or furane. The aggregate may be any natural crushed stone or similar material, but is preferably crushed powdered slate, silica sand, Quartz or calcium carbonate.
According to another preferred feature of the invention the aggregate and/or the synethic resin includes a fire resistant or retardant compound.
The synthetic resin is preferably a thermosetting plastic and is cured chemically and/or thermally, for example, by means of a "redox" couple, a peroxide, an azo initiator, press moulding, hor or cold, or by moisture. Conveniently the materials are cured in a metal or silicone mould or a plastic mould such as polythene, polypropylene or urethane, or a mould coated with a release aqent such as silicone wax. After a first moulding process, the curing is conveniently carried out for example in an oven, to produce a matt finish by evaporation of monom#i #r solvent from the surface surface.
The invention also consists in a method of producing a moulded building product, in which a mixture of a mouldable synthetic plastic resin and an inorganic particulate material is moulded or cast in or on a moulding surface and a monomer or solvent is evaporated from the surface, after "demoulding", to provide a matt finish and the appearance of natural stone or slate.
In a preferred process the mixture is vibrated and/or inserted in a vacuum chamber to allow trapped air bubbles to escape. Conveniently the mixture is first allowed to cure partly in the mould and then deposited onto a second mould surface for a final cure.
The invention may be performed in various ways and details of some preferred processes will now be described by way of example with reference to the accompanying drawings in which:
Figure 1 is a diagramatic, sectional elevation through a mould used in performing the invention, and
Figure 2 is a similar elevation illustrating a second stage in the process, and
Figure 3 is a diagram illustraging the microscopic appearance in section of the resultant surface.
In one procedure according to the invention
building material for use as an artificial roof slate
is manufactured by initially mixing a blend of aggregate
together with an adding resin. A suitable formulation
is below using silica sands although crushed slate,
quartz, calcium carbonate and other aggregate formulation
can be used,
Silica Sand 0.8 mm to 1.5 mm Dia 40%
Silican Sand 0.4 mm to 0.8 mm Dia 20%
Silica Sand 0.3 mm to 0.6 mm Dia 10%
Silica Sand 0.0 mm to 0.3 mm Dia 8%
Silica Flour 7%
Pigments 0.5% Peroxide 0.3%
Pre-Accelerated Polyester Resin 14. 2% To produce a 610 mm x 305 mm roof slate 2-2 kg
of the above mixture is placed in a silicone mould 10
which has been manufactured by casting silicone over
a natural slate.The silicone mould is treated with
a silicone release agentll.The material 9 is left in the
mould to cure after vibrating, to level and ensure all
entrapped air is removed, as shown in Figure 1. As
soon as the resin and aggregate has gelled, i.e.
partially polymerised, to a state where it is partly cured and has sufficient strength it is demoulded "faceup" onto a board as shown at 12 in Figure 2. The polyester resin chosen must be sufficient free monomer at this stage so that monomer evaporation from the surface during the final cure and exotherm creates a matt finish. The time for complete cure is dependent on the reactivity of the chosen polyester resins.
An alternative formulation for manufacturing a roof slate is given below:
Silica Sand 0.8 mm to 1.5 mm Dia 40%
Silica Sand 0.4 mm to 0.8 mm Dia 20%
Silica Sand 0.3 mm to 0.6 mm Dia 10% Silica Sand 0.0 mm to 0.3 mm Dia 8%
Silica Flour 7%
Pigments 0.5%
Epoxy Resin Component A (resin) 7.5%
Epoxy Resin Component B (hardener) 5%
Xylene 2%
The pigments and aggregates are mixed together and the two components of epoxy are mixed together and the solvent Xylene added to the epoxy.
The resin and aggregates are then mixed together and placed in a cold metal closed mould, which is manufactured by electrodeposition of nickel on to (chemically) plated natural slate. The complete mould assembly is placed under a press and left to start the cure.
Release agent (wax) is applied to the mould beforehand and after part-curing the roof slate is "demoulded",inverted, and placed in an air circulation oven at 120or to drive off the solvent to produce a matt surface finish.
The polymerisation procedure is illustrated by the following example of esterification of 1:1 mol of pentaerythritol with 2 mol of adipic acid:
Pentaerythritol Adipic acid
CH2 - OH O 0
HO-CH2-C-CH20H HO-C-CH2 CH2CH2CH2C-OH
CH2-OH
The ratio of reactive groups r is 4.4/4.0 = 1.1. If more than 55% of the hydroxyl groups are reacted (Pc o.55), the system will form a gel. The disruption of the surface creates a matt surface.
The temperature needed to carry out the process of matting-off is dependent upon the monomer/solvent used, and can be achieved or improved by air circulation or oven stoving.
Examples of some applicable solvents are as follows:
Acetone, Acetonitrile,Acrylonitrile,
n-Amylalcohol,Aniline, Benzene, n-Butanol,
tert-Butylalcohol, Carbon disulfide, Carbon
tetrachloride, Chlorobenzene, Chloroform,
Cyclohexane, Cyclohexanone, n-Decane,
Dietbylcarbonate, Diethylene glycol (DEG),
DEG, monobutyl ether, DEG, monoethyl ether,
Diethyl ether, N,N - Diformylpiperazine,
Diisopropyl ether, N,N-Dimethylacetamide,
N,N-Dimethylformamide, Dimethyl sulfoxide, 1,4-Dioxane, Ethyl acetate, Ethanol,
Ethylbenzene, Ethylene carbonate, Ethylene dichloride (or l,2-dichloroethane), Ethylene glycol (EG) EG, monobutyl ether or (2-butoxyethanol), EG, monoethyl ether or (2-ethoxyethanol), Ethylene oxide, 2-Ethylhexanol,
Formamide, Furfural, Glycerol, n-Heptane, n-Hexane, Isophorone, Isopropyl acetate,
Isopropyl alcohol, Kerosene (typical)
Methylene chloride, Methylethylketone, Nitrobenzene, Nitroethane,Nitromethane, l-Nitropropane, 2-Nitropropane, n-Pentane,
Perchlorethylene or tetrachloroethylene,
Piperidine,Propionitrile,n-Propyl alchohol,
Propylene glycol or (1,2-propanediol),
Propylene oxide, Pyridine, Styrene, Tetrahydrofuran, Toluene, 1.1,2-Trichloroethane, 1,1,2-Trichorethylene, l,l,l-Trichloro-2,2,2trifluoroethane, VM and P Naptha, Water,
Xylene (mixed)
The time scale for arriving at the gel state is dependent upon the polymer system used. For a Monomer such as Degamet 1400 (methylmethacrylate resin) supplied by Degussa, Germany, the gel time is approximately 30
PTn mins. For a polyester such as Polymaster 2685 TAL LSE (a polyester resin)supplied by K & K Mouldings (England) Limited.The gel time for the resin with a catalyst (Methyl Ethyl Ketone peroxide 50%) at 0.75% is approximately 45 mins.
Likewise when using a solvent such as xylene in an Epoxy resin:
Component A
Epoxy resin EEW180 (1) 84%
Reactive Solvent (2) 16% 100% Component B -,r1 Epilink/R 4018 (3) 100% Component C
Quartz sand 0.7-1.2 62.5%
Quartz sand 0.1-0.3 37.5% 100% (1) obtainable from Shell
(2) obtainable from EMS Chemie Ch
(e) obtainable from AKZO Chemie
The diagram of Figure 3 illustrates that the final surface of the moulded products has a general contour X derived from the mould surface and on to this is superimposed the small irregularities
Y derived from the evaporation of the monomer or solvent after preliminary moulding. It is the irregularities Y which give the necessary matt finish and without which the surface of the moulded product does not have a realistic resemblance to that of natural stone. In general the range of dimensional variation of the moulded contour X is of the order of 0.1 to 5.0 mm. while the range of dimensional variation on the microscopic scale, giving the matt surface rougness Y is of the order of O.lto 50 microns.
