Element iz mineralnih vlaken in postopek za izdelavo takega elementaMineral fiber element and process for making such element
Predloženi izum se nanaša na element iz mineralnih vlaken, zlasti za uporabo pri pripravi izolacijskega sloja z ojačeno površino.The present invention relates to a mineral fiber element, in particular for use in the preparation of a reinforced surface insulating layer.
V DK-B-131952 je opisan postopek za pripravo izolacijskih ločilnih sten iz blokov mineralne volne, kjer bloke mineralne volne potopijo v tekoč omet iz gipsa, kjer so njihove površine popolnoma pokrite z ometom iz gipsa, preden jih združijo s steno, in kjer omet iz gipsa nato pustijo, da se strdi, tako da nastane obloga ometa na tej steni. Navedeno je, da dobijo izolacijsko steno, ki izredno zavira gorenje in ima visoko sposobnost zvočne izolacije.DK-B-131952 describes a process for preparing insulating separating walls from mineral wool blocks, where blocks of mineral wool are immersed in a liquid gypsum plaster, where their surfaces are completely covered with plaster plaster before being combined with the wall, and where plaster the gypsum is then allowed to harden to form a plaster coating on that wall. It is stated that they get an insulation wall that is extremely fire retardant and has a high sound insulation ability.
Pri izdelavi obloge na steni, izdelani iz takih elementov iz mineralnih vlaken s potapljanjem elementov v omet iz gipsa, pride do številnih praktičnih problemov. Najprej je pri znanem postopku potrebna namestitev na mestu gradnje z gipsom napolnjenih posod, ki so zadosti velike, da potopijo elemente iz mineralnih vlaken v omet, in drugič bo transport elementov, pokritih z ometom iz gipsa, iz posode na mestu uporabe kot tudi gradnja sten z mokrimi elementi povzročila številne probleme pri rokovanju, vključno razlitje ometa iz gipsa ter umazanje opreme za transport in oseb, ki gradijo steno.There are a number of practical problems involved in making a wall covering made of such mineral fiber elements by immersing the elements in plaster plaster. First of all, the known process requires the installation of plaster-filled containers large enough to submerge mineral fiber elements into the plaster, and secondly, the transport of plaster-covered elements from the container at the site of use as well as the construction of walls Wet elements have caused many handling problems, including the spillage of gypsum plaster, and the dirt on transport equipment and persons constructing the wall.
V mednarodni patentni prijavi št. PCT/DK91/00071 je opisan postopek za izdelavo izolacijskega sloja z ojačeno površino, kjer elemente iz mineralnih vlaken, preslojene na eni ali več površinah, ki v coni, ki meji na to površino, vsebujejo vezivo, ki se da aktivirati, kombinirajo, da nastane izolacijski sloj, in kjer vezivo aktivirajo. Po prednostni izvedbi tega postopka uporabijo elemente iz mineralnih vlaken, ki vsebujejo hidravlično vezivo, prednostno cement, in vezivo aktivirajo bodisi na mestu izdelave, da nastanejo ojačani elementi, ki jih združijo na mestu uporabe, da nastane izolacijski sloj, ali na mestu uporabe po tem, ko so združili folije iz mineralnih vlaken, ki vsebujejo vezivo, da nastane izolacijski sloj. Tako v zadnjem primeru ne dobijo ojačene površine, dokler se hidravlično vezivo ne strdi.In international patent application no. PCT / DK91 / 00071 describes a process for the manufacture of a reinforced surface insulation layer, where mineral fiber elements coated on one or more surfaces containing an activating binder in a zone adjacent thereto are combined to an insulating layer is formed, and where the binder is activated. Preferably, this process utilizes mineral fiber elements containing a hydraulic binder, preferably cement, and activates the binder either at the site of manufacture to form reinforced elements, which combine at the site to form an insulating layer or thereafter , when they have combined mineral fiber films containing a binder to form an insulating layer. Thus, in the latter case, they do not gain a reinforced surface until the hydraulic binder has hardened.
Elemente iz mineralnih vlaken, ki vsebujejo vezivo, prednostno izdelajo s sesanjem finega suhega veziva, ki se da aktivirati, v površino elementov iz mineralnih vlaken.The mineral fiber elements containing the binder are preferably made by suctioning the fine, dry, activatable binder into the surface of the mineral fiber elements.
Sedaj smo presenetljivo ugotovili, da pri vdelavi prvega veziva v površino elementa iz mineralnih vlaken in preslojenju površinskega sloja, ki vsebuje vezivo, z materialom v obliki folije, vloženim v drugem vezivu, dobimo elemente s presenetljivo dobrimi lastnostmi glede trdnosti in/ali vsebnosti veziva.We have now surprisingly found that incorporating a first binder into the surface of a mineral fiber element and coating a binder surface layer with a foil material embedded in the second binder yields elements with surprisingly good strength and / or binder content properties.
Rezultat interakcije med vezivnim slojem, vdelanim v površino elementa iz mineralnih vlaken, in materialom v obliki folije, vloženim v drugem vezivu, je delno povečanje odpornosti za točkasto breme površinsko ojačenega elementa iz mineralnih vlaken in delno povečanje njegove prebijalne trdnosti in zlasti njegove prebijalne trdnosti ob dinamičnem vplivu. Zadnja lastnost je velikega pomena, kadar uporabljamo elemente iz mineralnih vlaken za izolacijsko strešno kritino ali fasadno kritino, ki je tako sposobna, da se upira mehanskemu vplivu, kot je hoja, udarci in sunki.The result of the interaction between the binder embedded in the surface of the mineral fiber element and the foil material lodged in the second binder results in a partial increase in the resistance to the point load of the mineral fiber surface reinforced element and in part an increase in its puncture strength and, in particular, its breaking strength at dynamic impact. The last feature is of great importance when we use mineral fiber elements for an insulating roof or façade that is so capable of resisting mechanical impact such as walking, bumps and shocks.
Kot alternativo povečani trdnosti lahko zmanjšamo količino veziva. Tako smo ugotovili, da lahko količino veziva v ploščah iz mineralnih vlaken, ojačenih s cementom, zmanjšamo za 20 do 50%, obenem pa zadržimo enake ali celo izboljšamo mehanske lastnosti.As an alternative to increased strength, the amount of binder can be reduced. Thus, we have found that the amount of binder in cement-reinforced mineral fiber boards can be reduced by 20 to 50% while maintaining the same or even improving mechanical properties.
Rezultat takega zmanjšanja veziva so delno nižji stroški proizvodnje in delno izboljšane toplotno izolacijske lastnosti vlaknenih elementov, t.j. izboljšanje vrednostiSuch a reduction in the binder results in partly lower production costs and partly improved thermal insulation properties of the fiber elements, i.e. improving value
λ.λ.
Prisotnost materiala v obliki folije v površinskem sloju tudi izboljša upogibno trdnost elementa. To je posebno važno, kadar uporabimo elemente iz mineralnih vlaken, zgrajene iz lamel s smerjo orientacije vlaken, ki je približno pravokotna na glavne površine elementov. V odsotnosti ojačanja površinskega sloja z materialom v obliki folije obstaja težnja, da se tvorijo razpoke v kotih takih elementov iz mineralnih vlaken. Tako je posledica materiala v obliki folije povečanje kotne trdnosti in robne trdnosti elementov.The presence of foil material in the surface layer also improves the flexural strength of the element. This is especially important when using mineral fiber elements constructed of lamellae with a fiber orientation direction approximately perpendicular to the principal surfaces of the elements. In the absence of reinforcement of the surface layer with foil material, there is a tendency to form cracks in the corners of such mineral fiber elements. Thus, the foil material results in an increase in the angular strength and edge strength of the elements.
Material v obliki folije prednostno izberemo iz skupine, ki obstoji iz netkanih materialov, tkanih materialov in pletenin.The foil material is preferably selected from the group consisting of nonwovens, woven fabrics and knitwear.
V primeru vlaknatega netkanega materiala je masa materiala v obliki folije prednostno med 10 in 100 g/m2, bolj prednostno 20-60 g/m2 in najbolj prednostno 30-50 g/m2.In the case of fibrous nonwovens, the weight of the foil material is preferably between 10 and 100 g / m 2 , more preferably 20-60 g / m 2 and most preferably 30-50 g / m 2 .
Prednostno obstoji material v obliki folije iz organskih vlaken ali iz kombinacij organskih in anorganskih vlaken, vendar lahko uporabimo anorganska vlakna, kot steklena runa, tudi sama. Primeri primernih organskih vlaken so poliestrska ali polipropilenska vlakna. Primer anorganskih vlaken so steklena vlakna.Preferably there is a material in the form of an organic fiber film or a combination of organic and inorganic fibers, but inorganic fibers such as glass fleece can be used alone. Examples of suitable organic fibers are polyester or polypropylene fibers. An example of inorganic fibers is glass fibers.
Prednostno je, da uporabimo material v obliki folije, ki popolnoma ali delno obstoji iz netkanega materiala, vendar pod pogojem, da ima sprejemljivo natezno trdnost, t.j. prednostno natezno trdnost med 20 in 600 N/5 cm, bolj prednostno 20-300 N/5 cm in najbolj prednostno 20-100 N/5 cm v smeri stroja kot tudi v prečni smeri stroja.It is preferable to use a foil-like material that is wholly or partially composed of a non-woven material, provided that it has an acceptable tensile strength, i.e. preferably a tensile strength of between 20 and 600 N / 5 cm, more preferably 20-300 N / 5 cm and most preferably 20-100 N / 5 cm in the machine direction as well as in the transverse machine direction.
V primeru tkanega materiala je prednostno, da uporabimo stekleno tkanino ali stekleni preplet. Prednostno ima tkani material maso med 60 in 150 g/m2. Tkani material lahko preslojimo, npr. z umetnimi snovmi.In the case of woven fabric, it is preferable to use a glass cloth or glass weave. Preferably, the woven material has a weight between 60 and 150 g / m 2 . The woven material can be coated, e.g. with plastics.
V primeru pletenin je prednostno, da uporabimo pletenine iz organskih sestavkov, kot poliestra ali polipropilena, ali iz anorganskega materiala, kot steklenih vlaken. Pletenine lahko preslojimo, če je ugodno.In the case of knitwear, it is preferable to use knitwear made from organic compositions such as polyester or polypropylene or from inorganic material such as glass fibers. Knit fabrics can be coated if convenient.
Nadalje pričakujemo, da lahko ojačevalna vlakna, npr. steklena vlakna kot taka, uporabimo kot ojačevalni material, vložen ali vdelan v drugo vezivo.It is further expected that reinforcing fibers, e.g. glass fibers per se are used as reinforcing material embedded or embedded in another binder.
Obe vezivi sta lahko različni, vendar je posebno prednostno, da sta vezivo, ki je vdelano v površinski sloj elementa iz mineralnih vlaken, in vezivo, v katerega je vložen material v obliki folije, identični.The two binders may be different, but it is particularly advantageous that the binder embedded in the surface layer of the mineral fiber element and the binder into which the foil material is inserted are identical.
Površinski sloj elementa iz mineralnih vlaken, v katerega je vdelano prvo vezivo, ima prednostno debelino vsaj 5 mm in bolj prednostno med 7 in 15 mm.The surface layer of the mineral fiber element into which the first binder is embedded preferably has a thickness of at least 5 mm and more preferably between 7 and 15 mm.
Prednostna veziva so hidravlična veziva, kot cement, gips, apno in pucolanske snovi. Vendar lahko uporabimo tudi plastična veziva, zlasti toplotno se utrjujoča plastična veziva.Preferred binders are hydraulic binders such as cement, gypsum, lime and pozzolanic substances. However, plastic binders can also be used, especially heat-curing plastic binders.
V primeru hidravličnega veziva mora vezivo s pridom vsebovati enega ali več dodatkov. Primeri takih dodatkov so pospeševalci utrjevanja, pigmenti, sredstva za odbijanje vode, kot silikon in vosek, katalizatorji kot tudi pospeševalci adhezije, kot polivinilacetat in akrilne spojine.In the case of a hydraulic binder, the binder should preferably contain one or more accessories. Examples of such additives are curing agents, pigments, water repellents such as silicone and wax, catalysts as well as adhesion promoters such as polyvinyl acetate and acrylic compounds.
Nadaljnje prednostno vezivo je Portland cement, kadar pa se uporablja, mora biti prednostno v količini 2-15 kg/m2.A further preferred binder is Portland cement, but when used, it should preferably be in the amount of 2-15 kg / m 2 .
Kadar uporabimo Portland cement kot drugo vezivo, ga mora biti prednostno 0,5-2,5 kg/m2 po utijevanju in bolj prednostno 0,5-1,5 kg/m2.When Portland cement is used as the second binder, it should preferably be 0.5-2.5 kg / m 2 after casting and more preferably 0.5-1.5 kg / m 2 .
Gostota elementa iz mineralnih vlaken je prednostno med 50 in 180 kg/m3 in je prednostno običajen element iz mineralnih vlaken, t.j. element iz mineralnih vlaken, ki so vezana druga na drugo s pomočjo toplotno se utrjujočega veziva, kot fenolformaldehidnega veziva.The density of the mineral fiber element is preferably between 50 and 180 kg / m 3 and is preferably a conventional mineral fiber element, i.e., a mineral fiber element bonded to one another by a heat-curing binder such as a phenol-formaldehyde binder.
Mineralna vlakna so prednostno vlakna iz kamene volne, vendar lahko uporabimo elemente drugih tipov sintetskih anorganskih vlaken, kot so steklena vlakna in žlindrna vlakna.Mineral fibers are preferably stone wool fibers, but elements of other types of synthetic inorganic fibers such as glass fibers and slag fibers may be used.
V običajni foliji iz mineralnih vlaken so vlakna normalno orientirana paralelno z ravnino folije.In conventional mineral fiber films, the fibers are normally oriented parallel to the plane of the film.
Vendar je lahko element iz mineralnih vlaken tudi sestavljen iz sosednjih lamel, kjer so vlakna pretežno orientirana v smeri, ki je v bistvu pravokotna na glavne površine elementa. Lamele so lahko med seboj povezane ali jih drži skupaj material v obliki folije, vložen v drugem vezivu.However, the mineral fiber element may also consist of adjacent lamellae where the fibers are predominantly oriented in a direction substantially perpendicular to the principal surfaces of the element. The slats may be interconnected or held together by a foil-like material lodged in another binder.
Kadar uporabimo elemente iz mineralnih vlaken lamelnega tipa, dosežemo posebno dobro penetracijsko globino veziva in pri tem posebno dobro vezanje ojačitvenega sloja, ki vključuje material v obliki folije. Nadalje ta orientacija vlaken poveča kompresijsko trdnost elementa.When lamella-type mineral fiber elements are used, a particularly good penetration depth of the binder is achieved, with a particularly good bonding of the reinforcement layer, which includes the foil-like material. Furthermore, this fiber orientation increases the compression strength of the element.
Izum se nadalje nanaša na postopek za izdelavo elementa iz mineralnih vlaken, kot je opisan zgoraj.The invention further relates to a process for making a mineral fiber element as described above.
Postopek je označen s tem, da suho prvo vezivo v obliki delcev, ki se da aktivirati, vsesamo v površino elementa iz mineralnih vlaken, da vezivo, ki se da aktivirati, aktiviramo, da površinski sloj, ki vsebuje vezivo, preslojimo z materialom v obliki folije, da material v obliki folije preslojimo s slojem aktiviranega drugega veziva in da pustimo, da se vezivi utrdita.The process is characterized in that the dry first binder in the form of an activatable particle is sucked into the surface of the mineral fiber element, the activator binder is activated, and the surface layer containing the binder is coated with the material in the form foil to coat the foil material with a layer of activated second binder and allow the binders to harden.
S postopkom dobimo površinsko ojačen element iz mineralnih vlaken s posebno nizko težnjo delaminiranja in visoko trdnostjo, zlasti kotno trdnostjo in robno trdnostjo.The process produces a surface-reinforced mineral fiber element with a particularly low tendency for delamination and high strength, in particular angular strength and edge strength.
Po prednostni izvedbi zgoraj opisanega postopka preslojimo površinski sloj, ki vsebuje vezivo, s slojem aktiviranega veziva pred kot tudi po aplikaciji materiala v obliki folije.According to a preferred embodiment of the method described above, the binder surface layer is coated with the activated binder layer before as well as after the application of the foil material.
Rezultat tega je posebno dobro vezanje materiala v obliki folije na element iz mineralnih vlaken.The result is a particularly good bonding of the foil material to the mineral fiber element.
Sesanje suhega veziva v obliki delcev, ki se da aktivirati, v površino elementa iz mineralnih vlaken prednostno izvedemo po postopku, opisanem v mednarodni patentni prijavi št. PCT/DK91/00071.Suctioning of the dry binder in the form of an activatable particle into the surface of the mineral fiber element is preferably carried out according to the method described in international patent application no. PCT / DK91 / 00071.
Hidravlično vezivo prednostno uporabimo, da tvorimo površinski sloj, vsesan v element iz mineralnih vlaken, in da tvorimo sloj ah sloje, ki vsebujejo drugo vezivo. Slednji sloj prednostno apliciramo v obliki vodne suspenzije (paste). Aktiviranje prvega veziva lahko izvedemo na različne načine glede na naravo veziva. Če je prvo vezivo hidravlično vezivo, kot cement, gips, apno in pucolanske snovi, vezivo aktiviramo z dodatkom vodnega medija k površinskemu sloju. Aktiviranje prvega hidravličnega veziva s pridom izvedemo z naprševanjem vode na površinski sloj ali z obdelavo površinskega sloja z zmesjo vode in vodne pare, pri čemer pospešimo utrjevanje prvega hidravličnega veziva.The hydraulic binder is preferably used to form a surface layer sucked into the mineral fiber element and to form a layer or layers containing a second binder. The latter layer is preferably applied in the form of an aqueous suspension (paste). Activation of the first binder can be accomplished in various ways depending on the nature of the binder. If the first binder is a hydraulic binder such as cement, gypsum, lime and pozzolanic substances, the binder is activated by adding an aqueous medium to the surface layer. Activation of the first hydraulic binder is advantageously accomplished by spraying water on the surface layer or by treating the surface layer with a mixture of water and water vapor, thereby accelerating the hardening of the first hydraulic binder.
Elementi iz mineralnih vlaken v smislu izuma so zlasti primerni za uporabo pri izdelavi izolacijskega sloja z ojačeno površino s kombiniranjem več takih elementov.The mineral fiber elements of the invention are particularly suitable for use in the manufacture of a reinforced surface insulation layer by combining several such elements.
Prednostni postopki za izdelavo takih izolacijskih slojev so opisani v mednarodni patentni prijavi št. PCT/DK91/00071.Preferred processes for the manufacture of such insulating layers are described in International Patent Application no. PCT / DK91 / 00071.
Izum bomo sedaj bolj podrobno opisali glede na naslednji primer.The invention will now be described in more detail with reference to the following example.

7230)7230)
Elemente iz mineralnih vlaken izdelamo na naslednji način:Mineral fiber elements are manufactured as follows:
Izhodni material, uporabljen za element iz mineralnih vlaken, je lamelna plošča, ki vsebuje fenolformaldehidno vezivo, ta lamelna plošča pa je izdelana iz medsebojno povezanih lamel, da dobimo dimenzije plošče 100 x 1200 x 600 mm. Lamele izdelamo iz Rockvvool® vlaken iz kamene volne in imajo gostoto 100 kg/m3 in sežigno izgubo 3,5%.The starting material used for the mineral fiber element is a lamella plate containing a phenolformaldehyde binder, and this lamella plate is made of interconnected lamellae to give a plate dimension of 100 x 1200 x 600 mm. The blades are made of Rockvvool® stone wool fibers and have a density of 100 kg / m 3 and a burning loss of 3.5%.
Prvo vezivo dodamo k izhodnemu materialu v obliki suhega Portland cementa v količini 4 kg/m2, pri čemer Portland cement sesamo v površino izhodnega materiala (lamelna plošča) na način, opisan v prijaviteljivi mednarodni patentni prijavi št. PCT/DK91/00071.The first binder is added to the starting material in the form of dry Portland cement in an amount of 4 kg / m 2 , whereby Portland cement is sucked into the surface of the starting material (lamella plate) in the manner described in the Applicant International Patent Application no. PCT / DK91 / 00071.
Portland cement, posesan v površino, aktiviramo z naprševanjem vode v količini 1,5 kg/m2 na površino.Portland cement sucked into the surface is activated by spraying water in an amount of 1.5 kg / m 2 per surface.
Kot drugo vezivo uporabimo zmes Portland cementa in vode v razmerju 1:1.As a second binder, use a 1: 1 mixture of Portland cement and water.
Količino 0,4 kg/m2 zmesi Portland cementa/vode nanesemo na površino plošče v tenkem sloju. Vlaknat netkan material z dimenzijami 1200 x 600 mm (FreudenbergApply 0.4 kg / m 2 of Portland cement / water mixture to the surface of the slab in a thin layer. Fibrous non - woven fabric, measuring 1200 x 600 mm (Freudenberg

Drug tenak sloj zmesi Portland cementa/vode nato nanesemo na netkan material v količini 0,4 kg/m2.Lutradur PE 7230) is placed on top of a thin layer of Portland cement / water. Another thin layer of Portland cement / water mixture is then applied to the non-woven material at 0.4 kg / m 2 .
Utrjevanje veziva, prisotnega v površini lamelne plošče, nato izvedemo z vzdrževanjem impregnirane lamelne plošče, ojačene z netkanim materialom, pri rahlo zvišani temperaturi in v vlažni atmosferi (40°C, 90% relativne vlage) sedem dni in noči.Hardening of the binder present on the surface of the lamella plate is then carried out by maintaining the impregnated lamella plate reinforced with non-woven material at a slightly elevated temperature and in a humid atmosphere (40 ° C, 90% relative humidity) for seven days and nights.
Za primerjavo izdelamo element iz mineralnih vlaken istega tipa, kot je element, opisan zgoraj, vendar brez netkanega materiala in drugega veziva, vendar s količino (prvega) veziva 9 kg/m2 (utijen).For comparison, we make a mineral fiber element of the same type as the element described above, but without the non-woven material and second binder, but with a quantity of (first) binder 9 kg / m 2 (woven).
V naslednjih primerih je prvi element iz mineralnih vlaken označen kot produkt A, element iz mineralnih vlaken brez netkanega materiala pa je označen kot produkt B.In the following cases, the first mineral fiber element is designated product A, and the non-woven mineral fiber element is designated product B.
