Definitions

• Insulating mat comprising a mineral fibre layer
• the present invention relates to a rectangular insulating mat comprising a mineral fibre layer made from a single unit of mineral
• the object of the present invention is to provide an insulating mat of the type stated in the introductory part of claim 1 by which it is possible to reduce or eliminate the release of loose fibres to the surroundings caused by the compression of the mat.
• the insulating mat according to the invention which is characterized in comprising an air-permeable covering which covers at least the predominant part of the two main surfaces of the mat and which is attached to the mat.
• the fact that the covering is attached to the mat instead of having the form of a loose envelope furthermore presents the advantage that it becomes easier to handle the mat as it is easier to get a grip of the mat, and the risk of tearing up the covering and the mineral fibre material during handling is considerably reduced.
• the mat according to the invention is advantageous in that it has a far better feel than a uncovered mat.
• the mat according to the invention differs from the above mentioned prior art mat in that it is made from a single unit of mineral fibre material as opposed to a number of rod-shaped units, and that the entire covering is air-permeable and compressible in a direction parallel with the plane of the mat, whereas the prior art mat is compressible in the longitudinal direction of one of the main surfaces and rigid in the longitudinal direction of the other main surface, which properties make it suitable for covering curved surfaces.
• matrix means a plate formed element
• air permeable covering means a covering having an air resistance of less than 100 mm water column.
• the covering used preferably has an air resistance of less than 50 mm water column and more preferably less than 25 mm water column.
• the air resistance of a material is defined as the pressure drop across the material measured in mm water column when an air stream having a velocity of 0.186 m/s is conveyed towards the material in a direction perpendicular to the plane of the material.
• the covering material used should have such an air permeability that the velocity at which the compression of the mat is effected in connection with its use is not reduced noticeably as compared to an uncovered mat and that it allows the mat to be machine-packaged under compression.
• the mineral fibre material used for the mat according to the invention may be produced by converting a mineral melt into fibres, adding a binder to said fibres and causing them to form a fibre web which optionally is subjected to a vertical compression in order to arrange the fibres in planes parallel with the surface of the fibre web and subsequently subjecting the fibre web to a longitudinal compression to obtain a fibre web in which the fibres are predominantly located in planes substantially perpendicular to the plane of the mat.
• a heat curable binder is preferably used, in which case the vertical and longitudinal compression is effected before the fibre web is subjected to a heat treatment for curing the binder.
• An alternative method of producing a mineral fibre material suitable for the mat according to the invention consists in folding a web of mineral fibre material, in which the fibres are located in planes parallel with the plane of the web, so as to form foldings extending parallel with the transverse direction of the web.
• the mineral fibre material preferably consists of rock wool fibres and preferably has a density corresponding to a weight of between 15 kg/m 3 and 60 kg/m 3 .
• the density is preferably between 10 and 60 kg/m 3 .
• binder which is conventionally used in the production of mineral fibre products may be used as a binder.
• a modified or unmodified phenol resin such as resol or novolak is preferably used.
• the covering may be applied directly to the mineral fibre material, e.g. by spraying, as described in i.a. international application No.
• the covering may be produced separately and subsequently be attached to the mineral fibre material by means of a layer of adhesive, by melting/welding or by sewing.
• non-woven coverings made from natural fibres such as fibres of cellulose, flax, coconut, hemp and the like, are useful.
• the covering material optionally contains a fire retardent agent which may be any known fire retardent agent, such as fire retarders containing halogen compounds, phosphor compounds or substances containing water or releasing water when exposed to heat.
• a fire retardent agent which may be any known fire retardent agent, such as fire retarders containing halogen compounds, phosphor compounds or substances containing water or releasing water when exposed to heat.
• said layer of adhesive may have the form of an air permeable, fully adhered layer, i.e. a layer covering substantially all the contact points between the covering material and the mineral fibre material, or it may have the form of separate zones of any form as well as bands, threads, stripes, dots or rows of dots.
• an adhesive layer in the form of bands, stripes or rows of dots extending perpendicularly to the direction in which the mat is most easily compressible.
• a preferred method of attaching the covering to the mineral fibre material consists in contacting pieces of the covering material with the surface of the mineral fibre material prior to the heat curing of the binder, and subsequently heat curing the binder.
• the binder particles located close to the surface of the mineral fibre layer form bonds between the covering and the mineral fibre layer and thereby bind the former to the latter.
• the method presents the advantage that use of an adhesive can be avoided, and as a result thereof the calorific value of the finished mat is reduced and the fire properties of the mat is thus improved.
• said covering is preferably made from a material having a high flexibility so that the covering does not reduce the compressibility of the mat to an unexpedient degree.
