Definitions
- the present invention relates to the field of construction materials, and more particularly the field of construction materials for buildings formed from a mineral wool mattress, for example of the glass wool type.
- Such construction materials are used in particular to provide thermal and/or acoustic insulation.
- Mineral wool mattresses are obtained by passing through an oven a mat of mineral fibers, made up on a conveyor device upstream of the oven by a mixture of mineral fibers, virgin or recycled, entangled with each other, and binding elements intended to bind the fibers together when passing through the oven.
- This mat of mineral fibers can be produced by different types of installation, for example by a fiberizing station and projection of liquid binder onto the mineral fibers obtained previously, the torus of mineral fibers thus glued falling onto a conveyor device guiding the together towards the oven.
- the mat of mineral fibers formed before the oven can be obtained in a station in which the mineral fibers and binding elements are blown into a box and sucked onto a conveyor device. guiding the whole towards the oven.
- the thermal and/or acoustic insulation performance of the mineral wool mattresses obtained after passing through an oven, consisting of non-woven fibrous materials, is notably a function of the arrangement of the fibers in the finished product, in order to avoid that a conduction bridge is formed from one side of the mattress to the other by a group of mineral fibers.
- This insulation performance thus depends in particular on the thickness and the volume density of the mineral fiber mattress as well as the interaction of the mineral fibers with the binder before passing through an oven.
- the present invention fits into this context and aims to provide a mineral wool mattress in which the thermal and/or acoustic insulation is improved by using a manufacturing installation mechanically depositing the mineral fibers on a conveyor device of the installation.
- the present invention relates to a mineral wool mattress comprising at least a plurality of mineral fibers superimposed on each other and next to each other within the mineral wool mattress, the mineral fibers being secured to each other. others by means of heat-binding fibers, the volume density of the mineral wool mattress being less than 40 kg.m' 3 and the thickness of the mineral wool mattress being greater than 50 mm.
- Such a mineral wool mattress is intended for building construction.
- the production of these panels is carried out by installations which mix the mineral fibers and deposit them mechanically on a conveyor device feeding an oven, so as to obtain an optimal configuration of the mineral fibers within the wool mattress.
- mineral The inventors were able to determine that this optimal configuration is obtained by the combination of a thickness of at least 50 mm and a volume density of the mineral wool mattress of at most 40 kg.m' 3 , and the use of heat-binding fibers.
- the mineral wool mattress according to the invention is, advantageously, obtained by a manufacturing installation by mechanical deposition of mineral fibers on a conveyor device taking the mineral fiber carpet to an oven in order to be heated there. Thermobonding fibers actively contribute to limiting the production costs of mineral wool mattresses by limiting maintenance and upkeep interventions.
- the mineral fibers are glass fibers.
- the thickness of the mineral wool mattress is greater than 100 mm.
- the thickness of the mineral wool mattress is greater than 250mm.
- the thickness of the mineral wool mattress which is to be considered here is the nominal thickness of the mattress, that is to say the thickness which can be observed by the user during the use which is made of the product to be for the purposes of insulating a building in particular.
- the mineral wool mattress according to the invention is obtained by passing through an oven, configured at a determined cooking temperature, a mat of mineral fibers, formed beforehand, the where appropriate on a conveyor device directing the carpet of mineral fibers towards the oven, by a mixture of mineral fibers, virgin or recycled, entangled with each other, and binding elements, here heat-binding fibers according to the invention, intended to bind the fibers together when passing through the oven.
- the nominal thickness can in particular be measured after packaging, for example when purchasing the product.
- the nominal thickness as mentioned above is observed after different successive stages of the industrial manufacturing process during the implementation of the product, these stages may include, after the drying mat has passed through an oven. mineral fibers, cutting into panels or rolls of appropriate dimensions of the mineral wool mattress obtained after passing through an oven, compressing these panels or rolls prior to a packaging operation, packaging and storage before marketing.
- the mat of mineral fibers is produced continuously, in a single pass during which the fibers participating in forming the mat of mineral fibers passing through the oven are deposited in series one on the others.
- the fibers participating in forming the mat of mineral fibers passing through the oven are deposited in series one on the others.
- the surface mass of the mineral wool mattress is greater than 4000 g.m' 2 .
- obtaining a mineral wool mattress of low density and thickness greater than what is known from the prior art implies a surface mass, or grammage, greater than what is known.
- the inventors were able to target a particularly advantageous combination of value ranges, with a density less than 40 kg.m' 3 , a thickness greater than 50 mm and a surface mass greater than 4000 g.m' 2 .
- the volume density of the mineral wool mattress is between 7 kg.m' 3 and 40 kg.m' 3 .
- the volume density of the mineral wool mattress is between 20 kg.m' 3 and 30 kg.m' 3 .
- the mineral fibers are secured to each other by a dry process.
- a dry process has the advantage of not dirtying the mechanical elements of a manufacturing installation, such as rollers between which the mineral fibers are intended to pass.
- binder in liquid form leads to covering the mechanical elements of the installation with binders which must be removed subsequently, which requires shutting down the manufacturing facility and therefore increasing the production costs of a mineral wool mattress.
- the mineral wool mattress comprises between 4% and 10% heat-binding fibers.
- the percentage of mineral fibers present in the mineral wool mattress is complementary to the percentage of heat-binding fibers.
- the mineral wool mattress is essentially made up of mineral fibers and heat-bonding fibers, the percentage of mineral fibers being around 90% when the percentage of heat-bonding fibers is around 10%. It should be noted that by “essentially formed” or “of the order of”, we aim to provide a margin of the order of 0.1 to 2%, in particular to provide for the presence of a coupling agent in the composition, in addition to mineral fibers and heat-binding fibers.
- the binding element is obtained by the fusion of the heat-binding fibers.
- thermobonding fiber is to be distinguished from mineral fibers insofar as it participates in forming the binding element associated with these mineral fibers, in particular by the fusion of a part of the sheath of the thermobonding fiber or by the partial melting of the heat-binding fiber itself.
- the distribution of the mineral fibers is homogeneous within the mineral wool mattress.
- the homogeneous distribution of the mineral fibers is achieved in particular by orienting each of the mineral fibers substantially in the same direction, and/or in several successive layers.
- the air is trapped within the mineral wool mattress between successive beds of mineral fibers.
- this distribution of the mineral fibers forms a resistance to the passage of air which tends to make the air immobile within the mineral wool mattress and thus increases the thermal and/or acoustic insulation properties of the mineral wool mattress.
- the inventors were able to determine that a homogeneous distribution of the mineral fibers within the mineral wool mattress, that is to say a homogeneous density, in particular due to a controlled arrangement of the mineral fibers, would allow for a range of products whose density is less than 40 kg.m' 3 , to obtain products going beyond the known performances of a mineral wool mattress for the same given density.
- At least the mineral fibers are distributed homogeneously within the mineral wool mattress, the homogeneous distribution of the mineral fibers being considered in a transverse and/or vertical direction, each of these directions being perpendicular to a main longitudinal elongation direction of the mineral wool mattress.
- the coefficient of variation of the distribution of the mineral fibers within the mineral wool mattress between at least a first lateral zone of the mineral wool mattress and a second lateral zone of the mineral wool mattress is less than 5%, the first lateral zone and the second lateral zone being offset relative to each other in a transverse direction perpendicular to the direction of main longitudinal elongation.
- these zones more specifically form bands having identical dimensions which can range from 10cm to 30cm depending on the protocols implemented.
- the mattress mineral wool can be cut into any number of strips that the width or thickness of these allows the coefficient of variation between each strip to be measured.
- the coefficient of variation of the distribution of the mineral fibers within the mineral wool mattress between at least a first vertical zone of the mineral wool mattress and a second vertical zone of the mineral wool mattress is less than 10%, the first vertical zone and the second vertical zone being offset relative to each other in a vertical direction perpendicular to the transverse direction and to the direction of main longitudinal elongation.
- the coefficient of variation is established between each of the strips of the mineral wool mattress, in relation to each other.
- the coefficient of variation of a zone is the same for every other zone of the mineral wool blanket.
- the distribution station 8 helps ensure the homogeneity, transversely and vertically, of the mineral fibers 2 within the mineral fiber mat 10. This homogeneity, in particular transverse, is made possible by spreading means, not visible in Figure 5 , provided at the end of the conveyor belt 42 closest to the distribution station 8. These spreading means make it possible to spread the mineral fibers 2 and the heat-binding fibers 3 over the entire transverse dimension of the rollers 811 of the train of rollers 81, this transverse dimension being parallel to the transverse direction of the mineral fiber mat 10.
