Description

GRANULIRANO RECIKLIRANJE POLIURETANSKIH OSTANKOV IN OSTANKOV BETONA NA OSNOVI AGREGATA IZ LAHKO PIHANEGA STEKLAGRANULATED RECYCLING OF POLYURETHANE RESIDUES AND CONCRETE RESIDUES BASED ON LIGHT-BREATHED GLASS AGGREGATES

Predloženi izum se nanaša na nov postopek, s katerim recikliramo neuporabni odpadni poliuretan in neuporabne ostanke betona na osnovi agregata iz lahko pihanega stekla. Neuporabni poliuretan in ostanki betona nastajajo v gradbeni dejavnosti ali drugi podobni dejavnosti. Z njim dobimo nov izolacijski material, primeren za namestitev v industrijske objekte, bivalne zgradbe ali objekte, ki zahtevajo toplotno izolativnost. Gre za področje kemijske tehnologije in sicer za poliuretanske in betonske odpadke, ki nastanejo kot gradbeni ostanki oziroma odpadki..The present invention relates to a new process for recycling useless waste polyurethane and useless residues of concrete based on a light-blown glass aggregate. Useless polyurethane and concrete residues are generated in the construction industry or other similar activity. It provides a new insulation material suitable for installation in industrial buildings, residential buildings or structures requiring thermal insulation. This is a field of chemical technology, namely polyurethane and concrete waste, which is generated as construction debris or waste.

Do sedaj znane rešitve pridobivanja izolacijskih materialov, ne glede na surovinsko osnovo, še niso podale tovrstne rešitve, kot je predlagana. Tehnični problem izuma jev tem, kako z enovitim tehničnim postopkom zavarovati okolje varstveni problem nastajanja velikih količin voluminoznega odpadka poliuretana in betona na osnovi agregata iz lahko pihanega stekla, ki nastaja kot gradbeni odpadek pretežno v gradbeni dejavnosti. Doslej se je zbiral v pločevinastih sodih ali vrečah v skladu s Pravilnikom o ravnanju z odpadki(Uradni list RS, št. 3/03) in Pravilnikom o dopolnitvah pravilnika o ravnanju z odpadki, ki nastanejo pri gradbenih delih (Uradni list RS, št. 50/04). V skladu z lO.členom Pravilnika o ravnanju z odpadki, ki nastanejo pri gradbenih delih investitorju ni treba naročiti prevzema od zbiralca gradbenih odpadkov ali oddaje gradbenih odpadkov neposredno v predelavo ali odstranjevanje pred začetkom del, če nastanejo gradbeni odpadki na gradbišču zaradi del, za katere ni treba pridobiti dovoljenja po predpisih o graditvi, količina gradbenih odpadkov pa v celotnem času izvajanja gradbenih del ne presega najmanjše količine iz tabele 1:To date, the known solutions for the production of insulating materials, regardless of the raw material base, have not yet provided such solutions as proposed. The technical problem of the invention is how to protect the environment with a uniform technical process, the protection problem of the generation of large volumes of polyurethane and concrete volumetric waste based on light-blown glass aggregate, which is generated as construction waste, mainly in the construction industry. So far, it has been collected in cans or sacks in accordance with the Waste Management Regulations (Official Gazette RS, No. 3/03) and the Rules on Amendments to the Rules on Waste Management arising from Construction Works (Official Gazette RS, No. 50/04). Pursuant to Article lO of the Rules on the management of waste arising from construction works, the investor need not be ordered to take over from the collector of construction waste or to dispose of construction waste directly for recovery or disposal before construction waste is generated due to works for which works no permit is required under the building regulations, and the amount of construction waste during the entire period of construction works does not exceed the minimum amount shown in Table 1:

Vrsta odpadkov Type of waste Najmanjša količina Minimum quantity Beton, opeka, ploščice, keramika in materiali na osnovi sadre Concrete, brick, tiles, ceramics and gypsum based materials 5 m3 5 m 3 Gradbeni material na osnovi azbesta Asbestos-based construction material 0,5 m3 0,5 m 3 Les, steklo, plastika Wood, glass, plastic 5 m3 5 m 3 Asfalt, katran in katranirani izdelki Asphalt, tar and tar products 50, m3 50, m 3 Kovine Metals 20 dm3 20 dm 3 Zemeljski izkop Earth excavation 500 m3 500 m 3 Izolimi materiali Isolated materials 1 m3 1 m 3

Tabela 1: Vrste odpadkov in najmanjša količinaTable 1: Types of waste and minimum quantity

Gre za majhne količine, ki so na večjih objektih presežene. Skladno z 12.členom in 13.členom omenjenega pravilnika investitorju tako preostane možnost, ponovne uporabe gradbenih odpadkov ali jih odstranjuje sam, če ima dovoljenje za predelavo ali odstranjevanje teh odpadkov po predpisu, ki ureja ravnanje z odpadki.These are small quantities that are exceeded on larger objects. Pursuant to Articles 12 and 13 of the said Regulations, the investor is thus left with the option of re-using construction waste or disposing of it himself if he is authorized to recycle or dispose of that waste in accordance with the regulation governing waste management.

V iskanju rešitve sem prišel do enkratne rešitve, iznašel sem postopek za pridobivanje novega izolacijskega materiala iz ostankov navedenih materialov, ki imajo uporabnost v obliki raznih plošč, sten, modelov ali kot sipki-granulirani obliki, primeren za polaganje kot toplotna izolacija, tako v horizontalni ravnini ali kot dodatek(polnilo) za izdelavo estrihov, sten, stropov. Na ta način je nov izolacijski material, izdelan po predloženem postopku, dobil vsestransko uporabnost v gradbeni industriji kot trdi ali sipki material.In finding a solution, I came up with a unique solution, I came up with a process for obtaining new insulation material from the remnants of the mentioned materials, which have usefulness in the form of various panels, walls, models or as granular-granular form, suitable for laying as thermal insulation, both in horizontal plane or as an additive (filler) for the production of screeds, walls, ceilings. In this way, new insulation material manufactured according to the present process has gained versatility in the construction industry as a hard or loose material.

Hkrati nam postopek omogoča na več načinov uničiti poliuretanske in betonske ostanek na osnovi agregata iz lahko pihanega stekla. V največji meri se tovrstni ostanki odlagajo na deponijah pooblaščenih organizacij, kjer zavzemajo veliko prostora.At the same time, the process allows us to destroy polyurethane and concrete residues on the basis of light-blown glass aggregate in many ways. To a large extent, this kind of waste is deposited in the landfills of authorized organizations, where they take up a lot of space.

V našem primeru smo proučili možnosti predelave betonov in izolimih materialov(poliuretana). Betonski ostanki pri gradnji objektov nastajajo v različnih fazah gradnje objekta, kot klasični gradbeni odpadek, s katerim je potrebno ravnati skladno s Pravilnikom za ravnanje z odpadki, ki nastanejo pri gradbenih delih. Na enak način se ravna z izoliranimi materiali. Poliuretanski odpadek nastaja kot odpadek pri izolaciji objektov, kjer se je potrebno prilagajati posameznim dimenzijam objekta.In our case, we examined the processing options for concrete and insulating materials (polyurethane). Concrete residues in the construction of structures are generated at various stages of construction of the facility, as classic construction waste, which must be handled in accordance with the Rules for the management of waste arising from construction works. It treats insulated materials in the same way. Polyurethane waste is generated as a waste in the isolation of buildings, where it is necessary to adapt to the individual dimensions of the building.

Pri snovanju rešitve postopka za recikliranje odpadkov, poliuretanskih ostankov in ostankov betona na osnovi agregata iz lahko pihanega stekla sem izhajal iz znanih tehničnih rešitev posameznih naprava, ki se uporabljajo v kemijski tehnologiji za razne tehnološke postopke kot so: mletje, trganje, stiskanje, rezanje, drobljenje, mešanje, sortiranje, lepljenje, sušenje, dodajanje aditivov ter izkušenj proizvajalcev izolacijskih materialov, betona in gradbenih podjetij in tudi na podobnih področjih predelave ostankov kot so plastika, papir, izkušnje v reciklaži avtomobilskih ostankov. S tem namenom, po predhodnih raziskavah in mojem izumu, sem ugotovil, da je smiselnost izuma v zagotavljanju drugačnega postopka za recikliranje ostankov poliuretana in betona na osnovi agregata iz lahko pihanega stekla z uporabo že znanih naprav ter jih postaviti v pravilno zaporedje mojega postopka, ki bo dal na koncu želeni rezultata, kar se kaže po zahtevi za podelitev patenta. Bistvena je ugotovitev, da sem prišel do novega izolacijskega material, ki kakovostno zadovoljuje vse predpisane standarde ter omogoča vsestranskost uporabe ter hkrati rešuje okoljsko problematiko. S predloženim izumom se rešuje stroškovna in okoljska obremenitev v gradbeni in drugih podobnih dejavnostih ter omogoča pooblaščenim organizacijam, kjer se na enem mestu odlagajo tovrstni odpadki dopolnilno dejavnost predelave.When designing a solution for recycling waste, polyurethane residues and residues of concrete based on light-blown glass aggregate, I started from the known technical solutions of individual devices used in chemical technology for various technological processes such as grinding, tearing, pressing, cutting, crushing, mixing, sorting, gluing, drying, adding additives and the experience of manufacturers of insulating materials, concrete and construction companies, as well as in similar areas of scrap processing such as plastics, paper, experience in the recycling of automotive scrap. To this end, according to previous research and my invention, I have found that it is reasonable to provide a different process for recycling residues of polyurethane and concrete based on light-blown glass aggregate using known devices and to place them in the correct sequence of my process will ultimately give the desired result, as evidenced by the patent application. It is a crucial finding that I have come up with a new insulation material that qualitatively meets all the prescribed standards and enables versatility and at the same time solves environmental problems. The present invention solves the cost and environmental burden of construction and other similar activities and enables authorized organizations where such waste is disposed of in one place to supplement the recovery activity.

Ugotovil sem, da se pojavljajo patentne prijave, ki obravnavajo reciklažo posameznih vrst odpadkov in ostankov raznih materialov, ki se navezujejo predvsem na recikliranje nepotrebnega papirja in drugih ostankov celuloze, plastike, odpadne gume, tudi recikliranje neuporabne poliuretanske pene in tekstilnih ostankov, ki nastajajo v tekstilni industriji, vendar nobena prijava ni reševala problema recikliranja poliuretana, betona iz lahko pihanega stekla, kombinacije le teh dveh materialov ter natančneje definirala nekaj proizvodov iz te reciklirane zmesi.I have found that there are patent applications addressing the recycling of certain types of waste and scrap of various materials, which are primarily related to the recycling of unnecessary paper and other residues of cellulose, plastics, waste rubber, including the recycling of useless polyurethane foam and textile residues generated in Textile industry, but no application solved the problem of recycling polyurethane, light-blown concrete, a combination of these two materials alone, and more specifically defined some of the products in this recycled mixture.

Pri pregledu prijavljenih izumov prijavitelju niso znani primeri tovrstne rešitve recikliranja. Pojavljajo se različne tehnične rešitve linij za reciklažo že navedenih ostankov, vendar za moj predmet zaščite ali za reciklažo poliuretana in betona iz lahko pihanega stekla po mojem postopku nisem zasledil podobno prijavljene rešitev. Navedel bom nekaj že prijavljenih rešitev, ki kažejo inovativnost rešitve in mi služi kot obrambni element pri dokazovanju moje inovacije:In reviewing the inventions reported, the applicant is not aware of examples of such recycling solutions. There are various technical solutions for recycling lines already mentioned, but for my object of protection or for the recycling of polyurethane and light-blown concrete, I did not find a similarly reported solution in my process. I will list some of the solutions already reported that demonstrate the innovativeness of the solution and serve as a defense element in proving my innovation:

IT BL92A000019, ki podaja rešitev za postopek izdelave trdih plošč iz ostankov papirja, celuloze in podobnih materialov.IT BL92A000019, which provides a solution for the process of manufacturing rigid sheets of scrap paper, pulp and similar materials.

SI 20267 A prav tako podaja rešitev uporabe celuloznih odpadnih materialov v povezavi s cementom.SI 20267 A also provides a solution for the use of cellulosic waste materials in connection with cement.

AT 1318/85 in AT 2896/85 obravnava stene iz opaža, ki so polnjene s stekleno volno, kar sicer ima podobnosti z uporabo v eni od uporabnih oblik mojega izolacijskega materiala,AT 1318/85 and AT 2896/85 deal with walls made of glass wool-filled formwork, which otherwise has similarities to the use in one of the useful forms of my insulation material,

EP 08429667 A2 obravnava kompozitni material pri proizvodnji steklenih in mineralnih vlaken iz steklene volne ter kot takšen nima nobene stične točke z mojim patentom,EP 08429667 A2 deals with composite material in the manufacture of glass and mineral fibers of glass wool and as such has no contact with my patent,

E 04 B 1/88 in E04 C 2/16 obravnava recikliranje odpadne poliuretanske pene in tekstilnih ostankov, ki ima stično točko predelave poliuretanske pene, vendar ne uporabi betona iz lahko pihanega stekla, ali kot veziva ali ko dodatka pri nastanku novega izolacijskega material po mojem postopku.E 04 B 1/88 and E04 C 2/16 deals with the recycling of waste polyurethane foam and textile residues having a contact point for the processing of polyurethane foam but not using light-blown concrete, or as a binder or admixture for new insulation material my procedure.

Po meni znanih podatkih, noben proizvajalec tovrstne opreme, ki je predlagana po patentu, do sedaj ni povzel v enovit celovit sistem takšne ali podobne naprave in na način, da je omogočena predelava poliuretanskih in betonskih ostankov na osnovi agregata iz lahko pihanega stekla.According to my knowledge, no manufacturer of such equipment proposed by the patent has so far integrated into a single comprehensive system such or similar apparatus and in such a way that processing of polyurethane and concrete residues on the basis of light-blown glass aggregate is possible.

Novost je predvsem v uporabi kombinacij tako posamičnih komponent za proizvodnjo poliuretanske izolacije, betona na osnovi agregata iz lahko pihanega stekla kot njunih ostankov po posamični ali kombinirani uporabi. Novost je izdelava novega izdelka predvsem iz poliuretanskih ostankov in ostankov betona na osnovi lahko pihanega stekla., ki je hkrati komercialne proizvod za široko uporabo zaradi kakovosti lastnosti izolativnosti.The novelty is especially in the use of combinations of both individual components for the production of polyurethane insulation, concrete based on light-blown glass aggregate and their residues after individual or combined use. The novelty is the production of a new product mainly made of polyurethane residues and residues of concrete on the basis of light-blown glass.

Z opisanim izumom je inovativno rešen problem vezanja drobljenih ostankov poliuretana in drobljenih ostankov betona na osnovi agregata iz lahko pihanega stekla oziroma mase obeh materialov, ki se lahko mešajo v razmerju 0:100 ali 100:0 ter dodatka tekočih faz poliuretana ali betona na osnovi agregata iz lahko pihanega stekla v razmerju 50:50, 60:40, 70 :30, 80:20, optimalno priporočljivo razmerje je 70% drobljenca in 30 % dodatka ali novega tekočega poliuretana ali novega betona na osnovi agregata iz lahko pihanega stekla po navodilih proizvajalcev.The present invention solves the problem of bonding the crushed residues of polyurethane and crushed residues of concrete based on light blown glass aggregate or the mass of both materials that can be mixed in a ratio of 0: 100 or 100: 0 and the addition of liquid phases of polyurethane or concrete based on aggregate made of 50:50, 60:40, 70: 30, 80:20 light blown glass, the optimum recommended ratio is 70% of crushed stone and 30% of admixture or new liquid polyurethane or new concrete based on light blown glass aggregate according to the manufacturer's instructions .

Osnovna ideja izuma izhaja iz možnosti ponovne mehanske in kemijske predelave oziroma recikliranja naštetih odpadkov. V eksperimentalnem delu sem prišli do naslednjih zaključkov:The basic idea of the invention comes from the possibility of recycling the mechanical and chemical recovery or recycling of the listed waste. In the experimental part I came to the following conclusions:

a) izolimi material/trdi poliuretan za izolacijo objektov je mogoče predelati z mehanskim drobljenjem in uporabo sveže poliuretanske mase ponovno v izolimi material,a) isolates material / hard polyurethane for the isolation of objects can be recovered by mechanical crushing and the use of fresh polyurethane mass again in the isolates material,

b) beton z agregatom iz lahko pihanega stekla je mogoče z mehanskim drobljenjem in tehnološko obdelavo ponovno predelati v reciklirani betonski proizvod.b) Concrete with light-blown glass aggregate can be re-processed into a recycled concrete product through mechanical crushing and technological treatment.

Z izvedeno rešitvijo ponovno vračamo v življenjski cikel (LCA - Life cycle assessment in metodo LCCA Life Cycle Cost Analysis)) proizvoda (gradbenega polizdelka) dva materiala in odpravimo gradbeni odpadek za poliuretanski izolimi material in beton na osnovi agregata iz lahko pihanega stekla. Na osnovi ugotovljenega stanja tehnike in izvedenih poskusov v proizvodnji sem potrdil določene prednosti postopka po izumu, ki se kaže v enostavnosti postopka.With the implemented solution, we return to the LCA (Life Cycle Assessment and LCCA Life Cycle Cost Analysis) product (construction semi-finished product) two materials and eliminate construction waste for polyurethane insulating material and concrete based on light-blown glass aggregate. On the basis of the state of the art and the manufacturing experiments carried out, I have confirmed certain advantages of the process according to the invention, which is evident in the simplicity of the process.

Izum bom prikazal s skicami kot sledi, ker menim, da je tako enostaven in da se potrebne naprave za njegovo realizacijo nahajajo v neomejenem številu izvedb po kakovosti in kapaciteti tako, da ga lahko vsakdo prilagodi svojim tehnološkim potrebam.I will show the invention with the sketches as follows, because I think that it is so simple and that the necessary devices for its realization are in an unlimited number of versions in quality and capacity so that everyone can adapt it to their technological needs.

Izum je opisan v naslednjih korakih in slikah, ki prikazujejo:The invention is described in the following steps and figures, which show:

Koraki postopka:Process steps:

a) drobljenje gradbenih ostankov poliuretanske izolacije in betonov na osnovi agregata iz lahko pihanega stekla v drobljenec velikosti od 1 dm3 do 5 dm3,a) crushing construction residues of polyurethane insulation and concrete based on light-blown glass aggregate into a shredder of size 1 dm 3 to 5 dm 3 ,

b) nasutje mešanega ostanka v kalup v razmerju od 0:100 do 100:0,b) pouring the mixed residue into the mold in a ratio of 0: 100 to 100: 0,

c) prelivanje ostankov (poliuretanskih, betonskih, mešanih, možne so vse tri variante: samo poliuretanski ostanek, samo betonski ostanek na osnovi agregata iz lahko pihanega stekla, ali kombinacija obeh v različnih razmerjih) s svežo poliuretansko maso obstoječe recepture proizvajalca z brizgalnim aparatom v kalupu alic) pouring of residues (polyurethane, concrete, mixed, all three variants are possible: only a polyurethane residue, only a concrete residue based on a light-blown glass aggregate, or a combination of both in different proportions) with the fresh polyurethane mass of the manufacturer's existing spray-molded formulation; mold or

d) prelivanje ostankov (poliuretanskih, betonskih, mešanih, možne so vse tri variante: samo poliuretanski ostanek, samo betonski ostanek na osnovi agregata iz lahko pihanega stekla, ali kombinacija obeh v različnih razmerjih) s svežim betonom na osnovi agregata iz lahko pihanega stekla recepture proizvajalca z betonsko črpalko v kalupu,d) overflow of residues (polyurethane, concrete, mixed, all three variants are possible: only polyurethane residue, only concrete residue based on light-blown glass aggregate, or a combination of both in different proportions) with fresh concrete based on light-blown glass recipe manufacturer with a concrete pump in the mold,

e) sušenje in utrjevanje novega proizvoda v skladu z navodili proizvajalca, glede na vrsto uporabljenega veziva (poliuretan ali beton iz lahko pihanega stekla)e) drying and curing of the new product according to the manufacturer's instructions, depending on the type of binder used (polyurethane or light-blown concrete)

f) razrez v želene dimenzije standardnih dimenzij.f) cutting into desired dimensions of standard dimensions.

Postopek recikliranja poteka tako, da poliuretanske in betonske odpadke na osnovi agregata iz lahko pihanega stekla mehansko zdrobimo v drobljenec/granulat (1), velikosti npr. od 1 dm3 do 5 dm3, ter z njim napolnimo kalup maksimalno do 80 % volumna kalupa (2). Slika 1 predstavlja kalup napolnjen z drobljencem gradbenih odpadkov poliuretana in betona na osnovi agregat iz lahko pihanega stekla. Drobljenec/granule prelijemo s svežo tekočo surovino za vlivanje poliuretana, ne glede na zvrst recepture poliuretana, saj nam le ta služi kot vezivo za drobljenec. Z brizgalnim aparatom ali betonsko črpalko v primeru betona iz agregata na osnovi lahko pihanega stekla, zapolnimo zračne votline (3) med ostanki poliuretanskega in betonskega drobljenca (1), tako da je omogočeno 100% oblivanje in vezava ostankov v zaprtem kalupu (2) npr. velikosti 3 m3. Ekspandiranje nove mase v zaprtem kalupu pod pritiskom 10-15 bar omogoča trdo vezavo. Zmes ostankov in nove poliuretanske mase pustimo v kalupu 72 ur, da utrdi po navodilih proizvajalca.The recycling process is carried out by mechanically crushing the polyurethane and concrete waste on the basis of an aggregate of blown glass into a shredder / granulate (1), e.g. from 1 dm 3 to 5 dm 3 and fill the mold with a maximum of 80% of the mold volume (2). Figure 1 represents a mold filled with a shredder of construction waste of polyurethane and concrete based on a light-blown glass aggregate. Pour the granules / granules with fresh liquid raw material for casting polyurethane, irrespective of the type of polyurethane recipe, as it serves as a binder for the crusher. Using an injection molding machine or concrete pump, in the case of concrete made of light-blown glass-based aggregate, fill the air cavities (3) between the residues of the polyurethane and the concrete crusher (1) so as to allow 100% pouring and bonding of the residues in a closed mold (2) e.g. . size 3 m 3 . Expansion of the new mass in a closed mold at a pressure of 10-15 bar allows for firm bonding. The mixture of residues and new polyurethane mass is left in the mold for 72 hours to cure according to the manufacturer's instructions.

V drugi verziji omogoča vezavo ostankov sveži beton na osnovi agregata iz lahko pihanega stekla. Postopek je enak, z ostanki napolnimo kalup(2) in za vezivo uporabimo svež beton, po recepturi in navodilih sušenja in utrjevanja proizvajalca.In the second version, fresh concrete based on a light-blown glass aggregate is allowed to bind the remains. The procedure is the same, fill the mold (2) with residues and use fresh concrete for the binder, according to the recipe and instructions for drying and curing the manufacturer.

Dobljeni produkt razrežemo v plošče (4) želene standardne dimenzije kot je prikazano na sliki 2. Gre za izdelavo plošč, namenjenih izolaciji, npr. estrihov v hiši, izolacijo hiš. Tako dobljeni produkt je primeren kot izolator v gradbeništvu.The resulting product is cut into panels (4) of the desired standard dimensions as shown in Figure 2. It is a matter of making panels intended for insulation, e.g. screed in the house, insulation of houses. The product thus obtained is suitable as an insulator in the construction industry.
