Description

i 5 EN 32617-Kp / cs Laminated compositions.

The invention relates to laminated compositions and more particularly to laminated compositions suitable as partitions, walls, decorative surfaces and the like.

The construction of laminated sheet materials has been intensively studied by industry. In particular, materials which are lightweight, have a good appearance, are robust and durable, and are also refractory or fire resistant. The last 10 aspects have mainly attracted attention. Interior surfaces in buildings, airplanes, automobiles and the like are often made from organic materials.

When such materials are exposed to heat or fire, toxic smoke is generated, which in many cases leads to suffocation or results in serious lung disease in persons exposed to such smoke. Accordingly, the industry has devoted a considerable amount of time and effort to develop products which have all of the aforementioned aspects, provided that they do not exhibit toxic smoke when exposed to fire.

A number of literature references have been found in the prior art which relate to the preparation of fire-resistant products. U.S. Pat. 2,744,589 relates, for example, to wall panel units, which consist of an insulated panel, the core being double insulated. The insulating materials appear to be rock wool materials and plasterboard according to this US patent. Likewise, U.S. Pat. 3,466,222 a combination of materials which in themselves would be unsuitable for use as flame retardants? but in the combined state they are suitable for making laminated materials which are said to be flame resistant.

Recently, U.S. Pat. 4,375,516 rigid, water-resistant phosphate-ceramic materials - 2 - materials and processes for their preparation. Both the foamed and non-foamed materials can be manufactured according to the procedures described in this patent, the products obtained being remarkably suitable for use as wall signs, ceiling signs, and the like. In addition, these products are flame resistant because they can be manufactured as perfectly or essentially inorganic compositions. Nevertheless, the products 10 produced according to the above patent are not entirely satisfactory for all purposes because they are rigid. That is to say, instead of bending under pressure, the plates tend to break.

Consequently, an object of the invention is to provide inorganic plates which are flexible, but are also strong and durable.

Another object of the invention is to provide flame resistant signs which swell when exposed to heat or fire and which produce little or no smoke.

Another object of the invention is to provide inorganic laminates which are flexible although made. from materials described in the prior art as materials suitable for the production of rigid products.

These and other advantages of the invention will be apparent from the following detailed preferred embodiments.

The present invention relates to laminated materials which are made using layers of reinforcing and / or non-reinforcing materials in combination with layers of a composition known in the art to be water-resistant phosphate. ceramic materials. In a preferred embodiment, the products are flame resistant and swell when exposed to heat or direct flames, producing little or no smoke. Nevertheless, these products are tough, durable and suitable for obtaining a decorative and fun appearance.

According to an embodiment, the invention relates to a bonded composition structure with at least 40 one layer of at least one type of layer material, wherein each 8500706 * 4-3 layer of each layer material is bonded to adjacent layers of layer material by means of a water resistant phosphate -binding material obtained by reaction of a mixture of a metal oxide, calcium silicate and phosphoric acid.

According to a second embodiment, the invention relates to a flame-resistant bonded composition with various layers of at least one type of layer material, and various layers of a water-resistant phosphate binding material, obtained by reaction of a mixture of a metal oxide, calcium silicate and phosphoric acid, each layer of layer material being bonded to the adjacent layers of layer material by means of the bonding material, the bonded composition having swelling properties when exposed to flame and / or heat.

According to a third embodiment, the invention relates to a method of manufacturing a bonded composition structure, which method is characterized by steps of manufacturing a layered composition with at least one layer of a phosphate bonding mixture 20 of a metal oxide, calcium silicate and phosphoric acid, which mixture provides a water-resistant phosphate bonding material, and at least one layer of at least one type of layer material, which composition is constructed such that the adjacent layers of the layer material are in contact with intermediate layers of the bonding mixture, which layered composition is cured by subjecting it optionally either to heat and / or pressure.

The unique characteristics of the products which can be manufactured according to the present invention are primarily due to the use of a phosphate bonding mixture suitable for providing a water resistant phosphate ceramic material. According to the prior art, such materials are suitable for providing a rigid, foamed and non-foamed phosphate ceramic products. Surprisingly, however, it has been discovered that when such blends are applied as relatively thin bond layers, they are suitable for providing laminated structures which are very flexible. Examples of mixtures suitable for obtaining this result are 8500706 V * - 4 - are described in U.S. Pat. 4,375,516.

This patent describes that mixtures of calcium silicate, phosphoric acid and a metal oxide selected from the group of alumina, magnesium oxide, calcium oxide and zinc oxide, as well as their hydrates, can be converted into water-resistant phosphate materials; although it has also been found that other metal oxides can also provide water resistant phosphate materials. Consequently, the present invention contemplates all mixtures of a metal oxide, calcium silicate and phosphoric acid, provided that these mixtures yield a water-resistant material after conversion.

These mixtures are applied, preferably in relatively thin layers on the order of approx.

0.025-0.51 mm thick, on the surface of a layer material, which can be a reinforcing or a non-reinforcing material. The mixture can be applied at normal consistency or they can be applied in the form of mechanically obtained foams. In case very thin layers are desired or where low weight laminates are desired, the latter technique is preferred, because the foam can be applied at a thickness of approx.

0.025 mm, after which the thickness decreases to a thinner layer after collapse of the foam. According to another alternative, the bonding mixture can be applied discontinuously to certain parts of the layer material. Accordingly, the term "low" bonding material is intended to mean applications where this material is deposited in a uniform or non-uniform manner.

After application of the bonding mixture, the coated material can be cured or covered with a second layer of the same or a different layer material, followed by curing. Curing can be accomplished under ambient conditions; where more dense products are desired, curing can be performed under pressure. In addition, heat can also be applied during curing to accelerate the curing process.

A wide variety of materials can be used to obtain the laminates described herein. For example, one can use 8500706-5. * Gebruik, for example, kraft paper, paper towels, cheesecloth, woven and non-woven glass mats, woven or non-woven synthetic material such as polyester, nylon and the like, chopped fibers of various materials , mineral wool, gauze and other well known materials as such or in combination with each other as low materials. In addition, use can be made of non-reinforcing materials, such as cementitious materials and the like, which in most cases will lead to products which are rigid.

Particularly effective reinforcing materials for use in combination with the phosphate bonding materials described herein are materials disclosed in related U.S. Patent Application No. 15 Series No. , and also in the U.S. patent

No. 4,239,519, as well as related patents. These patent documents collectively describe a group of materials referred to herein as "synthetic mica" materials. In essence, they are non-asbestos papers or cloths prepared from silica gels by cation exchange reactions. It is known that materials of this type are not affected by high temperatures while, moreover, they exhibit good flexibility.

Laminated structures with layers of the phosphate-bonding materials and synthetic mica fabrics have been found to have remarkable properties. For example, when exposed to direct flames, such compositions were not only found to be flame resistant and smoke-free, but were also found to have swelling properties. This means that through

exposure of one surface of the structure to direct flames an apparently internal delamination of the structure has occurred, resulting in air spaces. Such air spaces have been found to have an insulating effect, while significant heat differences have been noted between two sides of a structure which has been tested in this way. For example, if only one side of a relatively thin structure on the order of 1.52 mm thick was exposed to direct flames at a temperature of about 1121 ° C

8500706-6 - ψ * for 1 min, internal bloating occurred while the temperature on the opposite side of the structure was less than 316 ° C.

This phenomenon is not limited to laminates made using synthetic mica materials. For example, kraft paper laminates have also been shown to have swelling properties, with large temperature differences also observed in these laminates during the above study. The reason for the delamination nation is not clear, although it is believed to be due, at least in part, to the water contained in the structure.

In addition to swelling laminates, heat-conducting laminates can also be produced by including a mesh as one of the layers. Laminates of this type turned out to be very suitable for the removal of heat from the application site? these materials can therefore be used as heat-dissipating gaskets and the like.

The thickness of the laminates manufactured according to the invention can vary widely. The texture of the user may vary from very thin (e.g. 0.762 mm) to very thick (e.g. T2.7 mm or more) as desired by the user. Laminated structures have been prepared with only one layer of a reinforcing material and one layer of phosphate-bonding material, or with 37 layers of reinforcing layers and 36 layers of phosphate-bonding material. This illustration is by no means intended to limit the number of layers that can occur in a laminate. In addition, there is no need to limit the reinforcing materials used in the manufacture of the laminated structure to a single type, which means that combinations of reinforcing materials can be advantageously used.

The advantages of the present invention will be more apparent from the following examples, to which the invention is by no means limited, but which are merely illustrative.

EXAMPLES EXAMPLE I

A phosphate binding material was prepared from the following ingredients: 5 Components Weight (g) Al2O3.3H20 15.0

MgO 8.0

Talk 16.0 75% H, PO.

3 4 10 (53.0% P2Og) 105.0 H3B03 4.0

CaSiO 3 100.0 H 2 O 18.0

A phosphate bonding material was obtained by preparing a reaction solution consisting of phosphoric acid, alumina and water. After obtaining a clear solution while the solution was still hot, boric acid was added and the mixture was stirred until it became clear again. The reaction solution was cooled to 4 ° C, after which a mixture of the dry components was added.

Each of five dual layers of Reichhold Modi-glass 2.5X-SM scrim thin layers of 7.6 cm x 30.5 cm was quickly supplied with 0.076 mm layers of the above mixture. The five layers were immediately superimposed and compressed for 25 seconds at a pressure of 3.83 MPa in a press, which was heated to 121 ° C. The resulting layer was strong and water resistant, yet flexible.

The MOR of the laminate, measured according to ASTM 30 D-1037, was 14.5 MPa; the MOE value was calculated as 86.3 kg / cm2; and the NBS flame value was 0 for smolder and 2 for flame, measured according to ASTM E-662-79.

EXAMPLE II

The procedure described in Example I was repeated, except that the press was provided with a relief plate on one side. The sample obtained has been given the very fine details of the relief plate.

8500706 - 8 -

EXAMPLE III

A 0.025 mm layer of a phosphate bonding material agl having the composition described in Example I was applied to each of the ten separate sheets of kraft paper 5 measuring 30.5 cm x 30.5 cm x 0.030 cm. The ten sheets were immediately superimposed, then compressed for 1 min at a pressure of 3.86 MPa in a first press, which was heated to 93 ° C. The sample obtained was strong and flexible, although not as flexible as the glass-reinforced structure as set forth in Example 1. Its MOR value, measured in the manner described in Example X, was 31.0 MPa.

The bound composition structure was cut into 10.2 cm x 10.2 cm pieces, from which two pieces were randomly selected for examination. Each piece was placed horizontally on a ring stand and a thermocouple was placed in a place on the bottom surface where the blue propane flame was placed. A second thermocouple was placed on the top surface of the laminate directly above the first thermo-20 couple. When the flame was turned on, the temperatures of both thermocouples were measured from time to time. Sample 3A increased in thickness from 0.216 cm to 0.505 cm after heating for 7 min. At the end of that period, the flame side thermocouple measured a temperature of 1034 ° C, while the temperature on the top side was 328 ° C turned out to be. Sample 3B was heated for 6 min and showed an increase in thickness from 0.216 cm to 0.422 cm, while the temperature saf readings on the flame side and top side were 1007®C and 378 ° C, respectively.

EXAMPLE IV

A phosphate binding material, as set forth in Example X, was prepared except that the 50 wt% colored No. Contained 17 silica beads from Ottawa Silica Company. This was obtained by mixing the granules with the dry components, followed by the preparation of the phosphate binding material. The filled bonding material was applied at a thickness of 0.076 mm to each sheet of Johns-Manville glass paper, while at the same time, a layer of 0.076 mm was also applied to three separate triple sheets of 85007Q6-9 of Example I described Modiglass layer. The three Modi glass layers were superimposed, while the Johns-Man-ville glass paper was superimposed on top of the stack with the grain-filled bonding material on top. The material thus stacked was then compressed under a pressure of 3.83 MPa at a temperature of 104 ° C for 2 min to yield a flexible sheet with good scratch resistance.

10 EXAMPLE V

The procedure of Example IV was repeated, except that the press was embossed on one side. The product obtained showed fine details of the relief plate.

EXAMPLE VI

A phosphate binding material was prepared from the following components:

Components Weight (g) A1203.3H20 18.0 20 MgO 8.0

Talc 16.0 .75% H3PO4 (53.0% P205) 108.0 H3B03 4.0 25 CaSiO3 100.0 H20 18.0

The reaction solution was prepared by mixing phosphoric acid, water and alumina trihydrate, stirring the resulting mixture until a clear solution was obtained. Boric acid was added to the resulting warm solution and the solution was stirred. After this solution became clear, the reaction solution was cooled to about 2-4 ° C.

To the 148 g of cold liquid, 124 g of dry components were added with vigorous stirring after the whole was mixed to a uniform material. The resulting mixture was stirred until homogeneous, after which it was transferred to an ice bath to maintain the liquid consistency; 8500706 - 10 - that is, preventing the interaction of the components. The storage time of this material could be varied from 30 sec to about 7 min depending on the ability to control the exothermic reaction temperature in the ice bath.

A synthetic micavel was prepared from the following components mainly in the manner described in the related application:

Component Weight (g)

Magnesium fluorhectorite 100.0 10 Bleached redwood cellulose 10.0 0.318 cm DE glass fibers 5.0

Polyamine P flocculant 0.075

Hydraid 777 flocculant 0.037

Water The bleached redwood cellulose was dispersed in water using a hydropulper, after which the mixture was refined in a Jordan Refiner / to a son resistance of 500 (Canadian Freeness). The refined pulp was transferred to a large top-open tank and mixed with the glass fibers to form a slurry.

After adding the required amount of water to the tank to obtain a 1.3% solids consistency, the magnesium fluorhectorite flocculant was added and the mixture was stirred until homogeneous. Poly-25 amine P and Hydraid 7777 were then added, after which the mixture was immediately transferred to a mold screen of a Four-drinier machine. After removing most of the water, the mat was subjected to vacuum in a series of vacuum presses. The residual water was then removed by passing the synthetic mica mat over a heated drum.

A thin layer of the above phosphate bonding material (I) was applied by brush to a surface of a synthetic micavel (S) at a suitable thickness of 0.254 mm. A piece of microlith glass sheet (G), designated SH 20/1 from Glaswerk Schuller GmbH, was immediately placed into the bonding material and saturated, then a second synthetic micavel was applied on top of the glass layer. 8500706-11. The superimposed materials were transferred in a press between glass surfaces and compressed for 5 min at a temperature of 77 ° C and under a pressure of 1.72 MPa. After completing the pressing, the pressed composition was conditioned at 77 ° C for several minutes to remove water to yield a product that was strong and flexible.

It is noted that due to the porous nature of the glass sheet, the bonding material need not be applied on both sides of the glass sheet. The bonding material was able to pass through the glass layer under pressure (saturation) such that both adjacent layers of synthetic mica could be bonded to the glass by a single application of the bonding material. In this and the following examples, saturation is indicated by (GI) or (IG). As a result, the structure of this example had the laminar order S (IG) S.

EXAMPLE VII

A similar procedure as in Example 6 was repeated, except that the outer layers were formed by glass sheets and the composite material had the structure (GI) S (IG). The glass sheets were bonded with the phosphate binder to the synthetic micavel single inner layer by transferring the composition to a press equipped with shallow pattern relief plates. The plates gave a fine texture in a desired pattern to the surface of the laminate.

EXAMPLE VIII

The procedure of Example VII was repeated with the understanding that the composition material was placed between a foamed silicone rubber pad and male or female metal shapes which carried a pattern. This resulted in the production of molded products with deeply imprinted images.

EXAMPLE IX

A series of laminates were prepared essentially in the manner described in Example VI, each sample containing 8500706-12 synthetic mica, phosphate bonding material and optionally glass sheet. As in Example VI, the glass sheet was saturated by the phosphate binder such that when incorporated into a laminated structure, the binder served to bind the adjacent layers of synthetic mica together even when the binder was attached to only one surface of the glass sheet or only one of the adjacent synthetic mica sheets.

The fracture modulus (MOR) values were determined according to ASTM D-1037, while the modulus of elasticity (MOE) values were calculated via standard mathematical formulas from the MOR values. The structures of each laminate were indicated from top to bottom. Unless otherwise stated, the bonding material was placed in 0.203 mm deposits, while SH 20/1 glass sheet was used.

The results of these samples show a marked increase in strength when the glass sheet is applied to the laminate.

EXAMPLE X

This example illustrates the results when various samples were heated with a propane flame, as described in Example III. The results are presented below for laminates with various components and structural construction.

Substantial changes in the laminates became visible through heating, which changes were more pronounced as the number of layers increased. For example, when heating a single synthetic micavel, only a small expansion of the sheet was noticeable. However, when two or more synthetic mica and phosphate bonding layers (with or without glass reinforcement) were used, blistering became more pronounced. The effect with the thicker samples, as indicated below, was to provide good insulation properties. The table shows the increase in thickness induced by heating in each sample.

The samples were constructed from layers of SH 20/1 25 glass sheet and / or synthetic mica bonded together with phosphate bonding material of the type described in Example IX. The resulting laminates were embossed. They were referred to as samples 10A through 10H, while the "Structure" column indicates the laminar order from top to bottom. 30 Thickness change (cm)

The products were tested for tensile strength and also for flexibility. Tensile strengths were determined primarily according to ASTM F-152 using Type 1 sample measurements on an Instron tensile strength meter at 2.54 cm / min crosshead speed and a strip speed of 2.54 cm / min; however, the 20 samples were not preconditioned. The samples were cut in a 1.27 cm dumbbell shape, except for Example 11F, which was cut in a 2.54 cm dumbbell m. The following results were obtained:

The values given are an average of three measurements, with the numbers in brackets indicating the difference between the highest and lowest for each set of noted numbers 35.

The flexibility was determined according to ASTM F-147, which is generally referred to as a "spindle bending test". Samples 11A-11D were unable to pass the test with a 2.54 cm spindle 8500706-16; sample 11F passed a test using a 2.54 cm spindle; and sample 11E passed a test using a 2.22 cm spindle. None of the samples were preconditioned.

EXAMPLE XII

This example shows the heat conduction results that can be obtained by incorporating a metal mesh into a laminate. Laminate C of structure (GI) S (WI) S, was prepared in the usual manner, except that thermo-10 couples were incorporated into the structure by placing them on the top surface of the top synthetic mica plate. They were then held in place by applying the top (GI) layers. The thermocouples were placed at certain measured distances from the flame application location either in the wire direction (WD) or diagonally transverse to the mesh (skew), as follows:

Thermocouple Location Distance (cm) TC 1 place where the flame is applied TC 2 skewed 5.1 20 TC 3 skewed 10.2 TC 4 skewed 12.7 TC 5 skewed 15.2 TC 6 WD 10.2

Laminate C was prepared using galvanized iron mesh, as described in Example XI, while laminate B was prepared with a comparable copper wire. Laminate Ar containing no thread was prepared as a control. The following temperatures were measured.

These results show that a laminated mesh promotes heat conduction from the heating point, while 10 copper wires conduct more efficiently than galvanized iron wire. In addition, comparison of the results of TC 5 and TC 6 shows that the heat is conducted more efficiently in a wire direction than in an oblique direction.

EXAMPLE XIII

This example shows the preparation of a sample that was not cured under heat and pressure. A 0.015 mm layer of the bonding material, as described in Example I, (approx. 125 g) was applied to a 30.5 cm x 30.5 cm piece of 2.5X-SM Modiglass sheet, while a second piece of sheet 20 was applied on top of the layer. The layered material was briefly compressed in order to penetrate the bonding material into the respective thin layers, after which the composition was cured under chemical conditions. The curing took about 5 minutes.

EXAMPLE XIV

This example shows the application of a foamed bonding material to a layer of "sheet".

The binding material was prepared in the manner described in Example X and then mixed for 25 seconds. To the bonding material (268 g), 10.1 g (3.8%) of Millifoam surfactant from Onyx Chemical Co. the foam was obtained by mechanical mixing with an air stirrer for 40 sec. A 0.076 mm layer was applied to both surfaces of a 30.5 cm x 30.5 cm piece of 7.5X-SM Modi, glass-35 sheet, the total weight applied being approximately 82 g. The coated sheet was pressed at 85 ° C for 18 sec at 82 ° C to yield a cured sheet.

The present invention is not limited to the above described and illustrated, but includes all modifications of the following claims.
