Področje tehnikeField of technology
Predloženi izum se nanaša troslojno toplotno izolacijsko ploščo s sredinskim slojem iz kompozita na osnovi polistirena in celuloze ter dvema zunanjima slojema, ki se uporablja za toplotno izolacijo ovoja naprednega doma, ki omogoča vgradnjo toplotne izolacije tudi pod gradbeni objekt oz. pod temelje kot pasovno temeljenje ter s tem prekinitev toplotnih mostov v prehodnem območju med steno in temeljem.The present invention relates to a three-layer thermal insulation board with a middle layer of a composite based on polystyrene and cellulose and two outer layers, which is used for thermal insulation of the advanced home envelope, which allows the installation of thermal insulation under the building or. under the foundations as a strip foundation and thus the interruption of thermal bridges in the transition area between the wall and the foundation.
Toplotno izolacijski material po izumu spada v področje inženirskih gradbenih elementov za izvajanja toplotnih izolacij v gradbeništvu.The thermal insulation material according to the invention belongs to the field of engineering building elements for the implementation of thermal insulation in construction.
Opis tehničnega problemaDescription of the technical problem
Izoliranje stavb proti podlagi se izvaja s postavitvijo toplotne izolacije pod celotno tlorisno površino objekta in se izvede kot temeljenje na temeljni plošči. Ekstrudiran polistiren XPS ima premajhne vrednosti tlačne trdnosti in ne zdrži tlačne obremenitve za izvedbo toplotne izolacije izvedene samo pod temelji stavbe kot pasovno temeljenje. S tem je izoliranje stavbe omejeno na stavbe s tlorisno površino in celokupno maso ki lahko težnostno trajno deluje na to površino.Insulation of buildings against the ground is carried out by placing thermal insulation under the entire floor area of the building and is carried out as a foundation on the foundation slab. Extruded polystyrene XPS has insufficient values of compressive strength and does not withstand the compressive load to perform thermal insulation carried out only under the foundations of the building as a strip foundation. This limits the insulation of a building to buildings with a floor area and the total mass that can have a permanent gravitational effect on that area.

V patentni prijavi Sl 24397 je opisano temeljenje stavbe z uporabo polistirena XPS s tem da so v temeljno izolacijsko ploščo XPS vgrajeni kanali za prezračevanje in odvod radona izpod stavbe. Opisan polistiren XPS v ploščah ima trdnost 300 kPa in ni dodatno izboljšan za povečanje tlačne trdnosti, zato je stavba omejena na najmanj 100 m2 tlorisne površine. Znane so tudi rešitve z uporabo XPS plošč s tlačno trdnostjo 400 kPa izvedene kot temeljna plošča v dveh ploskovno položenih slojih XPS z vmesno folijo FIBRANhydro ANTIRADON 1,5 sk.Patent application Fig. 24397 describes the foundation of a building using XPS polystyrene, in that channels for ventilation and radon removal from under the building are built into the XPS foundation insulation board. The described XPS polystyrene in the panels has a strength of 300 kPa and is not further improved to increase the compressive strength, so the building is limited to at least 100 m 2 of floor area. Solutions are also known using XPS panels with a compressive strength of 400 kPa implemented as a base plate in two flat-laid XPS layers with an intermediate film FIBRANhydro ANTIRADON 1.5 sk.

Skupna značilnost vseh navedenih rešitev je v uporabi elementov iz nestisljivih materialov samih ali v kombinaciji z izolirnimi materiali. Pri pregledu baze patentov ni bilo najdenih sorodnih rešitev. Obstaja veliko inženirskih rešitev izvedbe izolacije pasovnih temeljev, ki pa niso izdelane iz ekstrudiranega polistirena XPS z dodatkom celuloze, ter ne pokrivajo rešitev iz predmeta izuma.A common feature of all these solutions is the use of elements made of incompressible materials alone or in combination with insulating materials. No related solutions were found during the review of the patent database. There are many engineering solutions for the insulation of strip foundations, which are not made of extruded polystyrene XPS with the addition of cellulose, and do not cover the solutions of the subject invention.
Opis nove rešitveDescription of the new solution
Bistvo troslojne toplotno izolacijske plošče s sredinskim slojem iz kompozita na osnovi polistirena in celuloze je v tem, da z dodatkom celuloze izboljšamo mehanske lastnosti ekstrudiranega polistirena in tako omogočimo vgradnjo toplotne izolacije tudi pod stavbo oz. pod temelje stavbe.The essence of the three-layer thermal insulation board with a middle layer of composite based on polystyrene and cellulose is that with the addition of cellulose we improve the mechanical properties of extruded polystyrene and thus enable the installation of thermal insulation under the building or. under the foundations of the building.
Po izumu je tehnični problem rešen s troslojno toplotno izolacijsko plošča s sredinskim slojem ki je izdelan iz kompozita na osnovi polistirena in celuloze. Plošča je sestavljena iz treh slojev: sredinski sloj je kompozit izdelan na osnovi ekstrudiranega polistirena z dodatkom celuloze in zunanjih slojev iz ekstrudiranega polistirena. Sloji so med seboj zlepljeni prednostno s polietilenom.According to the invention, the technical problem is solved with a three-layer thermal insulation board with a middle layer made of a composite based on polystyrene and cellulose. The board consists of three layers: the middle layer is a composite made on the basis of extruded polystyrene with the addition of cellulose and the outer layers of extruded polystyrene. The layers are glued together preferably with polyethylene.
Dodatek celuloze v sredinskem sloju izboljša upogibno in tlačno trdnost vendar zaradi hidrofilne narave celuloze poveča absorpcijo vlage. Z zunanjima slojema sredico zaščitimo pred vplivom vlage, hkrati pa ohranimo mehanske lastnosti plošče. Takšna plošča omogoča vgradnjo tudi pod stavbo oz. pod temelje stavbe kot pasovno temeljenje.The addition of cellulose in the middle layer improves the flexural and compressive strength but due to the hydrophilic nature of the cellulose increases moisture absorption. The outer layers protect the core from the effects of moisture, while maintaining the mechanical properties of the plate. Such a panel also allows installation under the building or. under the foundations of the building as a strip foundation.
Sredica je kompozitna plošča sestavljena iz polistirena in celuloze. Vlakna celuloze so prednostno iz nano fibrilirane celuloze. Izdelava sredice se izvede z postopkom ekstruzije. Količina dodane celuloze je prednostno 10 masnih % na 100 masnih % polistirena. Za izboljšanje vezilne interakcije med nepolarno matrico iz polistirena in polarno celulozo se v proces ekstruzije doda kompatibilizator, prednostno 8 % malein anhidrida v polistirenu, prednostno v 2 masnih % na 100 masnih % polistirena.The core is a composite panel made of polystyrene and cellulose. The cellulose fibers are preferably made of nano fibrillated cellulose. The core is made by the extrusion process. The amount of cellulose added is preferably 10% by weight to 100% by weight of polystyrene. To improve the bonding interaction between the non-polar polystyrene matrix and the polar cellulose, a compatibilizer is added to the extrusion process, preferably 8% maleic anhydride in polystyrene, preferably in 2% by weight per 100% by weight of polystyrene.
Zunanji plasti sta prav tako izdelani s postopkom ekstruzije.The outer layers are also made by an extrusion process.
Prednost troslojne toplotno izolacijske plošča s sredico iz kompozita na osnovi polistirena in celuloze je v tem, da ohrani lastnosti odpornosti na vlago ki jih ima izolacijska plošča iz ekstrudiranega polistirena, s sredninskim slojem v katerem so v polistiren vkomponirana celulozna vlakna, pa izboljšamo mehanske lastnosti plošče.The advantage of a three-layer thermal insulation board with a core made of a composite based on polystyrene and cellulose is that it retains the moisture resistance properties of an extruded polystyrene insulation board, and with the middle layer in which cellulose fibers are incorporated into the polystyrene, we improve the mechanical properties of the board. .
