Definitions
- the present invention relates to panels for use in building construction.
- the present invention relates to panels for providing partitions to which items such as sinks, televisions, or radiators may be affixed.
- Light-weight panels such as plasterboard (e.g. gypsum plasterboard), polystyrene board and fibreboard are commonly used to provide partitions within buildings. Their advantages for this application include the fact that they are light and quick to install.
- such light-weight panels may have the drawback that they are not strong enough to support fixtures (e.g. sinks, televisions, radiators, fire extinguishers, shelves and any other item that requires attachment to the panel).
- the weight of the fixture may cause the fixing means (e.g. screws) to be pulled out of the panel, such that the fixture falls away from the partition.
- the backing lamina being e.g. PVC, HDPE, Nylon, polycarbonate, Bakelite, polypropylene, acetal, or fibreglass.
- the plasterboard may be provided with sufficient ability to retain fixing means that no backing lamina is required.
- the present invention may provide a plasterboard comprising a gypsum matrix having particles of agglomerated fibres embedded therein in an amount of at least 1 wt % relative to the gypsum, the gypsum matrix further comprising a polymeric additive, the polymeric additive being present in an amount of at least 1 wt % relative to the gypsum;
- the panel By omitting a backing lamina, it may be possible to provide a panel having adequate fixing strength at a relatively lower cost, due to reduced raw material costs and greater ease of manufacture. Additionally, the panel may be easier to recycle, since the requirement to separate the lamina from the plasterboard may be avoided.
- lamina is intended to cover polymer-based sheets having a thickness of at least 1 mm (for example 2 mm), comprising substantially PVC, HDPE, Nylon, polycarbonate, Bakelite, polypropylene, acetal, or fibreglass.
- laminate is used herein to refer to a sheet that is attached to a face of a plasterboard, e.g. by gluing, such that there is a defined interface between the plasterboard and the sheet.
- the term “lamina” is not intended to refer to objects that are partially or wholly embedded within the plasterboard.
- the plasterboard may have paper facings on one or both sides thereof.
- the plasterboard may have a mat partially or fully embedded at its surface, for example, a glass fibre mat.
- the particles are present in an amount of at least 2 wt % relative to the gypsum, preferably at least 2.5 wt %. Typically, the particles are present in an amount of less than 10 wt % relative to the gypsum, preferably less than 8 wt %.
- the particles may be, for example, wood particles (such as woodchip or fine sawdust particles) or paper particles.
- the particles are wood particles.
- the particles are irregular in shape.
- wood particles is not intended to refer to particles of wood-derived material (such as paper particles) that have been processed to the point where individual fibres are no longer bound by the natural binders present in wood.
- these particles have a length that is greater than 0.5 mm. In general, these particles have a length that is less than 25 mm, preferably less than 20 mm.
- these particles have a thickness than is less than 4 mm, preferably less than 3 mm. In the case that the particles are paper particles, their thickness is typically less than 0.5 mm.
- the particles may be wood particles and the plasterboard may further comprise glass fibres.
- the glass fibres are preferably present in an amount of at least 1 wt %.
- the polymeric additive is present in an amount of at least 2 wt % relative to the gypsum, preferably at least 4 wt %.
- the polymeric additive is selected from group comprising polyvinyl acetate, poly vinyl acetate-ethylene co-polymer, polyvinyl pyrrolidone crosslinked with polystyrene sulfonate, polyvinyl alcohol, methyl cellulose, hydroxyethyl methyl cellulose, styrene-butadiene copolymer latex, acrylic ester latex, acrylic copolymer latex, polyester resin, epoxy resin, polymethyl methacrylate, polyacrylic acid, cationic starch, ethylated starch, dextrin and mixtures thereof.
- the polymeric additive is one of polyvinyl acetate and starch.
- the starch may be a native starch (that is, an unmodified starch). In other cases, the starch may be a modified starch, for example, an acid-thinned starch.
- the polymeric additive is polyvinyl acetate.
- the present invention may provide a plasterboard comprising a gypsum matrix having wood particles embedded therein in an amount of at least 2 wt % relative to the gypsum, the gypsum matrix further comprising glass fibres in an amount of at least 1 wt % relative to the gypsum.
- no backing lamina is attached to either face of the plasterboard.
- lamina is intended to cover polymer-based sheets having a thickness of at least 1 mm (for example 2 mm), comprising substantially PVC, HDPE, Nylon, polycarbonate, Bakelite, polypropylene, acetal, or fibreglass.

- the wood particles have a thickness than is less than 4 mm, preferably less than 3 mm.
- the plasterboard has paper facings. These paper facings may comprise both cellulose fibres and glass fibres, as this is thought to improve the fire resistance of the plasterboard. In other cases, the plasterboard may have a mat partially or fully embedded at its surface, for example, a glass mat.
- the gypsum matrix comprises a hydrophobic additive, such as silicone oil or wax.
- the gypsum matrix may contain a biocide.
- the gypsum matrix may contain an anti-shrinkage agent such as unexpanded vermiculite, microsilica, and/or clay, in order to improve the fire-resistance of the product.
- an anti-shrinkage agent such as unexpanded vermiculite, microsilica, and/or clay, in order to improve the fire-resistance of the product.

- Screw pull-out tests were carried out on samples measuring 100 mm by 100 mm that had been conditioned at a temperature of 23° C. and a relative humidity of 50%.
- a 50 mm single thread wood screw was inserted into the sample, passing through a metal load transfer element positioned on the surface of the sample.
- the load transfer element has a first portion that is configured to lie between the screw head and the surface of the sample, and a second portion that is configured to engage with a testing machine so as to allow a load to be applied to the screw along the axis of the screw.
- the screw was tightened to a torque of 1 Nm.
- the specimen was then mounted in a Zwick Universal Testing Machine and a 10 N pre-load applied to the screw along the axis of the screw. Subsequently, the load was increased by setting a constant cross-head speed of 10 mm/minute until pull out was achieved.

- Light-weight panels such as plasterboard (e.g. gypsum plasterboard), polystyrene board and fibreboard are commonly used to provide partitions within buildings. Their advantages for this application include the fact that they are light and quick to install.
- However, in certain cases, such light-weight panels may have the drawback that they are not strong enough to support fixtures (e.g. sinks, televisions, radiators, fire extinguishers, shelves and any other item that requires attachment to the panel). In such cases, the weight of the fixture may cause the fixing means (e.g. screws) to be pulled out of the panel, such that the fixture falls away from the partition.
- This problem has previously been addressed by gluing a polymer-based backing lamina to one face of the plasterboard, the backing lamina being e.g. PVC, HDPE, Nylon, polycarbonate, Bakelite, polypropylene, acetal, or fibreglass.
- It has now been found that by including wood products and a polymeric additive in the plasterboard, the plasterboard may be provided with sufficient ability to retain fixing means that no backing lamina is required.
- Therefore, in a first aspect, the present invention may provide a plasterboard comprising a gypsum matrix having particles of agglomerated fibres embedded therein in an amount of at least 1 wt % relative to the gypsum, the gypsum matrix further comprising a polymeric additive, the polymeric additive being present in an amount of at least 1 wt % relative to the gypsum;
-
- wherein
- no backing lamina is attached to either face of the plasterboard.
- By omitting a backing lamina, it may be possible to provide a panel having adequate fixing strength at a relatively lower cost, due to reduced raw material costs and greater ease of manufacture. Additionally, the panel may be easier to recycle, since the requirement to separate the lamina from the plasterboard may be avoided.
- The term “lamina” is intended to cover polymer-based sheets having a thickness of at least 1 mm (for example 2 mm), comprising substantially PVC, HDPE, Nylon, polycarbonate, Bakelite, polypropylene, acetal, or fibreglass. The term “lamina” is used herein to refer to a sheet that is attached to a face of a plasterboard, e.g. by gluing, such that there is a defined interface between the plasterboard and the sheet. Thus, the term “lamina” is not intended to refer to objects that are partially or wholly embedded within the plasterboard.
- Although no lamina is attached to either face of the plasterboard, the plasterboard may have paper facings on one or both sides thereof. In other cases, the plasterboard may have a mat partially or fully embedded at its surface, for example, a glass fibre mat.
- Typically, the particles are present in an amount of at least 2 wt % relative to the gypsum, preferably at least 2.5 wt %. Typically, the particles are present in an amount of less than 10 wt % relative to the gypsum, preferably less than 8 wt %.
- The particles may be, for example, wood particles (such as woodchip or fine sawdust particles) or paper particles. Preferably the particles are wood particles. In general, the particles are irregular in shape.
- For the avoidance of doubt, the term “wood particles” is not intended to refer to particles of wood-derived material (such as paper particles) that have been processed to the point where individual fibres are no longer bound by the natural binders present in wood.
- Typically these particles have a length that is greater than 0.5 mm. In general, these particles have a length that is less than 25 mm, preferably less than 20 mm.
- Typically, these particles have a thickness than is less than 4 mm, preferably less than 3 mm. In the case that the particles are paper particles, their thickness is typically less than 0.5 mm.
- In certain embodiments, the particles may be wood particles and the plasterboard may further comprise glass fibres. In such cases, the glass fibres are preferably present in an amount of at least 1 wt %.
- Typically, the polymeric additive is present in an amount of at least 2 wt % relative to the gypsum, preferably at least 4 wt %.
- Typically, wherein the polymeric additive is selected from group comprising polyvinyl acetate, poly vinyl acetate-ethylene co-polymer, polyvinyl pyrrolidone crosslinked with polystyrene sulfonate, polyvinyl alcohol, methyl cellulose, hydroxyethyl methyl cellulose, styrene-butadiene copolymer latex, acrylic ester latex, acrylic copolymer latex, polyester resin, epoxy resin, polymethyl methacrylate, polyacrylic acid, cationic starch, ethylated starch, dextrin and mixtures thereof.
- Preferably, the polymeric additive is one of polyvinyl acetate and starch.
- In certain cases, the starch may be a native starch (that is, an unmodified starch). In other cases, the starch may be a modified starch, for example, an acid-thinned starch.
- Most preferably, the polymeric additive is polyvinyl acetate.
- In a second aspect, the present invention may provide a plasterboard comprising a gypsum matrix having wood particles embedded therein in an amount of at least 2 wt % relative to the gypsum, the gypsum matrix further comprising glass fibres in an amount of at least 1 wt % relative to the gypsum.
- Typically, no backing lamina is attached to either face of the plasterboard.
- The term “lamina” is intended to cover polymer-based sheets having a thickness of at least 1 mm (for example 2 mm), comprising substantially PVC, HDPE, Nylon, polycarbonate, Bakelite, polypropylene, acetal, or fibreglass. The term “lamina” is used herein to refer to a sheet that is attached to a face of a plasterboard, e.g. by gluing, such that there is a defined interface between the plasterboard and the sheet. Thus, the term “lamina” is not intended to refer to objects that are partially or wholly embedded within the plasterboard.
- Although no lamina is attached to either face of the plasterboard, the plasterboard may have paper facings on one or both sides thereof. In other cases, the plasterboard may have a mat partially or fully embedded at its surface, for example, a glass fibre mat.
- In general, the wood particles are irregular in shape.
- Typically the wood particles have a length that is greater than 0.5 mm. In general, these particles have a length that is less than 25 mm, preferably less than 20 mm.
- Typically, the wood particles have a thickness than is less than 4 mm, preferably less than 3 mm.
- In certain embodiments of the first or second aspects of the invention, the plasterboard has paper facings. These paper facings may comprise both cellulose fibres and glass fibres, as this is thought to improve the fire resistance of the plasterboard. In other cases, the plasterboard may have a mat partially or fully embedded at its surface, for example, a glass mat.
- In certain embodiments of the first or second aspects of the invention, the gypsum matrix comprises a hydrophobic additive, such as silicone oil or wax.
- In certain embodiments of the first or second aspects of the invention, the gypsum matrix may contain a biocide.
- In certain embodiments of the first or second aspects of the invention, the gypsum matrix may contain an anti-shrinkage agent such as unexpanded vermiculite, microsilica, and/or clay, in order to improve the fire-resistance of the product.
- Certain embodiments of the first or second aspects of the invention may include foam or lightweight aggregate such as perlite. Such additives are known in the art to produce lower-density boards having acceptable thickness.
- The invention will now be described by way of example only.
- Gypsum plasterboards were prepared using the following general methodology: Stucco and other dry additives (including woodchips) were weighed into a bag and shaken to mix them. Water and wet additives were weighed into a bowl and mixed using an electric mixer for 60 s.
- The dry powdered additives were added to the wet additives in the bowl and mixed in with the electric mixer for 30 s.
- The resultant slurry was sandwiched between two sheets of paper liner and allowed to hydrate for 25 minutes measured from the time of mixing. The board was then dried in an oven for 1 hour at 160° C.
- The panels had a thickness of 12.5 mm.
- A gypsum plasterboard was prepared from a slurry containing the following ingredients:
-
- stucco;
- woodchips in an amount of 3wt % relative to the stucco. The woodchips had a maximum dimension in the range 1-20 mm and a thickness of 0.5-3 mm;
- corn starch (Merifilm from Tate & Lyle) in an amount of 6 wt % relative to the stucco.

- Screw pull-out tests were carried out on samples measuring 100 mm by 100 mm that had been conditioned at a temperature of 23° C. and a relative humidity of 50%. A 50 mm single thread wood screw was inserted into the sample, passing through a metal load transfer element positioned on the surface of the sample. The load transfer element has a first portion that is configured to lie between the screw head and the surface of the sample, and a second portion that is configured to engage with a testing machine so as to allow a load to be applied to the screw along the axis of the screw. The screw was tightened to a torque of 1 Nm.
- The specimen was then mounted in a Zwick Universal Testing Machine and a 10 N pre-load applied to the screw along the axis of the screw. Subsequently, the load was increased by setting a constant cross-head speed of 10 mm/minute until pull out was achieved.
- The results are set out in Table 1. These are averages, each taken from 8 samples.
