Definitions
- the present invention relates to an insulating panel based on mineral fibers such as glass fibers, glass wool, rock wool and the like, and to a method for producing such an insulating panel.
- mineral fibers such as glass fibers, glass wool, rock wool and the like
- Des. thermal insulation panels which are generally used to insulate electrical appliances, in particular household appliances, for example kitchen ovens, electric or microwave ovens, refrigerators, boilers, conditioners or air conditioners and the like, are widely used on the market.
- Such panels provide a core of insulating material, for example glass fibers, which is optionally coated on one side or on both sides with an aluminum film.
- the aluminum coating layer is applied to improve the handling of the panels, to retain the dust created by the glass fibers, to reduce the risk of fraying of the glass fibers and their sticking when the panels are stacked or stacked.
- These panels are generally placed outside the opening of the household appliance, the aluminum coating of the panel generally being arranged on the face of the panel which faces towards the exterior of the household appliance. In general, these panels are not visible and are placed in a gap formed in the box of the household appliance. In general, before being assembled on the household appliance, these panels are preformed with holes which are suitable for accommodating fixing means and for allowing, for example, the passage of the electric cables of the household appliance.
- Insulating panels of the known technique have various drawbacks, which are mainly due to the electrical and thermal conductivity characteristics of the aluminum coating layer.
- the aluminum coating which is electrically conductive, risks creating short- dangerous circuits.
- the aluminum coating is moreover not sufficiently elastic and therefore flexible and is more likely to break, in addition to the risk of cutting on the edges.
- the glass fiber core is a good thermal insulator
- the aluminum coating is a good conductor of heat
- first molten glass is introduced into a fiber production machine from which emerge glass fibers which are mixed with the binder and fall on a conveyor belt on which they undergo a air suction to then be transported in an oven to stabilize the binder.
- these glass fibers gathered on the conveyor belt can undergo a needling operation to obtain a mechanical bond by using special hook needles.
- the glass fiber mat with its aluminum coating is rolled up in rolls or possibly cut to form semi-finished panels which are cut so as to obtain the desired dimensions with advantageous fixing and cable passage holes .
- the rolls or panels of the semi-finished product are sent to a final drying phase, to dry the adhesive used for applying the aluminum coating.
- the object of the present invention is to eliminate the drawbacks of the known technique by proposing a insulating panel based on glass fibers which has good thermal insulation characteristics and at the same time ensures good electrical insulation.
- Another object of the invention is to provide an insulating panel which is extremely flexible and which eliminates any risk of being cut.
- Yet another object of the present invention is to provide such an insulating panel which is versatile, practical for the user, economical and simple to produce.
- Another object of the present invention is to provide a method for producing an insulating panel based on mineral fibers which is efficient, rapid and at the same time economical and simple.
- this object is achieved with the methods of producing an insulating panel, the phases of which are set out respectively in claims 13 and 19 appended.
- the invention finally relates to the use of such an insulating panel in an electrical appliance, in particular household appliances, such as those mentioned above.
- the insulating panel based on glass fibers according to the invention comprises a core of glass fibers bonded together and a coating layer connected to at least one face of the core of glass fibers.
- the particular feature of the invention consists in the fact that the covering layer comprises a woven-nonwoven (TNT), a fabric of mineral fibers or a veil of mineral fibers, in particular glass fibers.
- TNT woven-non-woven
- the covering layer will be designated mainly as a woven-non-woven layer (TNT), also commonly called "non-woven”.
- the woven-nonwoven is a good insulator, both electric and thermal.
- the result is that we eliminate the risk of short circuit of the electric cables which cross the panel and at the same time, we do not notice sudden thermal jumps between the glass wool core and the woven covering layer. -nonwoven.
- the TNT coating improves the handling of the panel by guaranteeing a better feeling to the touch by the user than the panels with an aluminum coating.
- TNT is more elastic and flexible than aluminum, in addition to improving the handling of the panel, the risks of breaking the edges of the panel are avoided.
- FIG. 1 is a flow diagram which represents schematically the process for producing an insulating panel based on mineral fibers according to the invention
- FIG. 2 is a flow diagram which schematically represents a second embodiment of the method for producing an insulating panel based on mineral fibers.
- FIG. 1 we now describe a first embodiment of the process for producing the insulating panel based on glass fibers according to the invention.
- a piece of molten glass 1 is sent to a fiber production machine 2 which produces a plurality of glass fibers 10.
- the machine implements a rotary fibering process known as internal centrifugation, in which the molten material is received in a rotary member with symmetry of revolution called plate, having a wall pierced with a plurality of orifices through which the molten material is ejected and supported by a draft gas stream.
- internal centrifugation a rotary fibering process known as internal centrifugation, in which the molten material is received in a rotary member with symmetry of revolution called plate, having a wall pierced with a plurality of orifices through which the molten material is ejected and supported by a draft gas stream.
- the machine is adjusted to produce fibers characterized by a micronaire of the order of 3 to 4.5 under 5 g.
- the fibers advantageously have a micronaire of the order of 3 to 3.8 in 5 g.
- the glass fibers 10 coming out of the machine 2 from fiber production are transported through a spray ring 3 in which one or more binders are sprayed which combine with the glass fibers 10 in order to promote a chemical bond between them.
- binders mineral binders can be used such as, for example an aqueous solution of aluminum polyphosphate salts.
- glass fibers mixed with the binders 11 leave the spraying machine 3 and are collected on a support 9 so as to form an uncompact mass 12 of glass fibers and binder in which the binder exerts its action of bonding on glass fibers.
- the support 9 has the form of a ribbon which is unwound from a mother reel 90 and which is advanced in the direction of the arrow F A by means of a conveyor 4.
- the support 9 is a strip made of woven-nonwoven (TNT), glass fabric or glass veil.
- the support 9 is preferably composed of a woven-nonwoven based on plastic material, for example polyethylene and / or polyester derivatives, to which are optionally added fillers of metal oxides.
- a vacuum cleaner 5 which has the function of sucking the air from the not very compact mass 12 of glass fibers and binder through the support 9 so as to suck the dust from the glass fibers and at the same time promote a first reduction in the humidity of the fibers and binders.
- a pressure roller 6 Downstream of the vacuum cleaner 5, but also of the mass of glass fibers 12, is placed a pressure roller 6 which has the function of carrying out a first compacting of the glass fibers so as to obtain a core or a carpet; essentially homogeneous glass fibers 13 arranged on the support 9.
- the adhesion of the lower support 9 to the glass fiber mat 13 is guaranteed by the suction phase carried out by the vacuum cleaner 5, during which the humidity of the binder is decreased.
- a second mother reel 90 ′ is used from which a strip of TNT 9 ′ is unwound, advantageously essentially identical to the coating 9 unwound by the first mother reel 90.
- an inking "group 7 which comprises a binder dispensing roller which takes up the binder in a tank situated underneath and extends it on the lower surface of the TNT strip 9 ′.
- the binder used in this phase can be the same binder as that used in the spraying machine 3 in other aqueous solutions, or be a different mineral binder.
- the need to use the ink unit 7 is due to the fact that downstream of the vacuum cleaner 5, the binder added to the glass fibers during the spraying phase is generally too dry or even completely dried and is therefore not generally suitable. to ensure the grip of the upper support on the glass fiber mat 13.
- the core of mineral fibers generally has a thickness of the order of 15 to 35 mm. , in particular of the order of 20 to 30 mm.
- the glass fiber mat 13 sandwiched between the lower support 9 and the upper support 9 ′ is advanced by means of a conveyor belt lower 80 and an upper conveyor belt 80 'in an oven 8 which causes the drying of the binder deposited by the ink unit 7 and consequently the adhesion of the upper support 9' on the glass fiber mat 13 and the stabilization of the adhesive between the fibers.
- the operating temperature of the binder drying oven 8 is in the range of 100 ° C to 200 ° C.
- the layer of glass fibers 13 to which the lower support and the upper support 9, 9 'are bonded is taken up in a roll or is cut and cut directly so as to obtain insulating felts of appropriate dimensions, consisting of a layer of glass fibers 13 bonded together and bonded to at least one support 9, 9 'by means of mineral type binders.
- insulating felts of appropriate dimensions, consisting of a layer of glass fibers 13 bonded together and bonded to at least one support 9, 9 'by means of mineral type binders.
- the glass fibers 10 exit from the fiber production machine 2 are not mixed with binders capable of creating a chemical bond between the fibers.
- binders capable of creating a chemical bond between the fibers.
- agents a minimal amount of agents is used, the sole purpose of which is to retain dust and not to create a chemical bond between the fibers.
- Fomblin® a type of agent known per se is used as anti-dust additives.
- the fibers advantageously have a micronaire of the order of 3.5 to 4.5 in 5 g.
- the glass fiber mat 112 is advanced between two supports 9, 9 'unwound from a first and a second mother reel 90, 90'. It is clear that if the coating on one side of the fibers is desired, one of the two coils 90, 90 ', preferably the upper coil 90', can be omitted. Downstream of the coils 90, 90 ', respective coupling rollers 170, 170' suitable for tensioning the respective supports 9, 9 'are provided below and above the glass fiber mat 112. The fiber mat glass 112 with the respective supports 9, 9 ′ is advanced by means of a conveyor 140 in the direction of arrow F A towards a needling machine 108.
