Description

(54) AN INSULATING BOARD OF MINERAL WOOL (71) We, RocKwooL LAPINUS B.V., formerly B.V. Nederlandse Steenwolfabriek, a Netherlands limited liability company of 15, Industrieweg, Roermond, the Netherlands, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The invention relates to an insulating board of mineral wool, particularly of rock wool.
A board of this type, consisting of mineral wool, particularly of rock wool, which is impregnated during manufacture with a thermosetting resin, whereupon this thermosetting resin is cured by passing the board through a heating zone, is known and used.
An insulating board of this type presents the drawback that when same is applied to a surface to be insulated, which has previously been provided with a bitumen coating, large quantities of bitumen are absorbed.
This presents the disadvantage that on the one hand the cost of insulation increases, while on the other hand considerable quantities of matrial are consumed, which impairs the insulating properties of the insulating board, since the bitumen is absorbed in recesses in the insulating board, which serves for insulation.
It has already been proposed to overcome this trouble by providing particular surface layers on such an insulating board but this method has found no practical use, since in that case special upper layers of water glass and additions of mineral substances should be used. Moreover this method is attended with a decrease of insulating properties and the consumption of bitumen is still high.
It is now an aim of the invention to provide a board of the aforementioned type which does not show these drawbacks and which retains its insulating properties and has a considerably smaller consumption of bitumen.
According to the invention there is provided an insulating board of mineral wool impregnated with a cured thermosetting resin, wherein the board has an outer layer defined by a fabric which does not soften below 100"C.
Such a fabric may be formed of mineral fibres, which may be reinforced, and preferably is formed of non-woven glass fibres.
The advantages of a layer of non-woven glass fibres is that the consumption of bitumen ranges from one to one and a half kilogram per square meter, whereas without such a layer, the quantity of bitumen consumed amounts of 2.5 to 3 kg per square meter.
The layer of non-woven fibres may consist of reinforced glass fibre in order to obtain a reinforcement so that the resistance to spot load of the insulating structure can be considerably increased. As a consequence the ability of the insulating layer to be walked on is improved which in practice has considerable advantages.
It has surprisingly been found that not only the consumption of bitumen is limited by the use of the layer of non-woven glass fibres but that bitumen also penetrates into the board of mineral wool in such a manner that a proper adherence is obtained between the layer and the mineral wool. It could be expected that on account of the open texture of the layer the expenditure on bitumen would be very small; this is, however, not the case.
Advantageously a layer of non-woven mineral fibres has a surface weight ranging from 20 to 60 g/m2, preferably from 40 to 50 g/m2, impregnated with 15 to 30% by weight, preferably about 20% by weight, of a cured thermosetting resin, preferably a phenol formaldehyde resin is used.
The invention also provides to a method of manufacturing an insulating board of mineral wool comprising the steps of passing the mineral wool impregnated with a thermosetting resin through a heating zone, wherein, prior to, or during the passage through the heating zone, a layer of fabric which does not soften below 100"C, is applied to an outer surface of the mineral wool.
As a result the fabric unites through the thermosetting resin, with the outer surface of the mineral wool. Moreover, a very flat board surface is obtained which assists in reducing the consumption of bitumen, since evidently lack of smoothness of the board automatically increases the consumption of bitumen.
The invention further provides a method of insulating a surface by applying thereto an insulating board of mineral wool as described in any of the last six but two preceding paragraphs, a bitumen coating being provided in contact with the layer of fabric.
In this manner a considerable expenditure on bitumen is obtained, while moreover the fabric layer is caused by the bitumen to adhere to the mineral wool.
The invention is hereinafter clarified with reference to the accompanying drawing in which one embodiment is shown by way of example only.
In the drawings: Fig. 1 shows a section through an insulating board of mineral wool according to the invention; Fig. 2 represents another embodiment of such a board applied to a surface to be insulated, and Fig. 3 shows on a larger scale a detail of the surface of a conventional insulating board.
In the drawings an insulating board 1 is shown consisting of rock wool 2, having insulating spaces 3, the rock wool being impregnated during manufacture with a thermosetting polyester resin, said thermosetting resin being cured in a heating zone at a temperature comprised between 140 to 1700C.
An outer surface 4 of the insulating board of mineral wool is very irregular, which implies that when such a board is applied onto an insulating surface 5 a high quantity of bitumen of the bitumen coating layer 6 is consumed. The bitumen namely is absorbed by the mineral wool.
To obviate these difficulties a fabric layer 7 is applied to the surface of the mineral wool. This layer 7 consists preferably of non-woven glass fibres and has a surface weight of 45 git2, impregnated with 20% b.w. of phenol formaldehyde resin.
Due to the application of this layer 7 prior to the setting of the resin in the mineral wool, the layer 7 adheres properly to the mineral wool during curing of the thermosetting resin.
The application of the layer of non-woven glass fibres has the advantage that a very smooth surface of the board is obtained, whereby the consumption of bitumen can be considerably reduced, while moreover it has been surprisingly found that due to the application of the layer the proper adherence between the board and the surface to be insulated is retained.
This is apparent from the fact that when a non-woven layer is in use, the consump tion of bitumen is reduced to 1 to 1,5 kg/m2 instead of the normal quantity of 2,5 to 3 kg/cm2.
If desired the non-woven layer 7 can be reinforced, whereby the resistance to local loads of the insulating sheet can be considerably increased. This results in an improved ability of the structure to be walked on.
Obviously the resin in the mineral wool may also first be cured and the structure subsequently smoothed, whereupon the nonwoven layer is applied.
Through the invention has been explained with reference to a board of rock wool, it will be obvious that the invention is also applicable to a board of for instance glass wool.

Moreover, a very flat board surface is obtained which assists in reducing the consumption of bitumen, since evidently lack of smoothness of the board automatically increases the consumption of bitumen. The invention further provides a method of insulating a surface by applying thereto an insulating board of mineral wool as described in any of the last six but two preceding paragraphs, a bitumen coating being provided in contact with the layer of fabric. In this manner a considerable expenditure on bitumen is obtained, while moreover the fabric layer is caused by the bitumen to adhere to the mineral wool.

In the drawings an insulating board 1 is shown consisting of rock wool 2, having insulating spaces 3, the rock wool being impregnated during manufacture with a thermosetting polyester resin, said thermosetting resin being cured in a heating zone at a temperature comprised between 140 to 1700C. An outer surface 4 of the insulating board of mineral wool is very irregular, which implies that when such a board is applied onto an insulating surface 5 a high quantity of bitumen of the bitumen coating layer 6 is consumed. The bitumen namely is absorbed by the mineral wool. To obviate these difficulties a fabric layer 7 is applied to the surface of the mineral wool. This layer 7 consists preferably of non-woven glass fibres and has a surface weight of 45 git2, impregnated with 20% b.w. of phenol formaldehyde resin. Due to the application of this layer 7 prior to the setting of the resin in the mineral wool, the layer 7 adheres properly to the mineral wool during curing of the thermosetting resin. The application of the layer of non-woven glass fibres has the advantage that a very smooth surface of the board is obtained, whereby the consumption of bitumen can be considerably reduced, while moreover it has been surprisingly found that due to the application of the layer the proper adherence between the board and the surface to be insulated is retained.
