Abstract
Description
Izum se odnosi na postupak za prekrivanje daske od iverice, osobito daske debljine od 10 do 40 mm, i koja ima dva glavna suprotna površinska sloja površinske gustoće iznad 800 kg/m3 i čvrstoću pokrovne ploče od 8 do 12 kg/cm2, rečeno pokrivanje, za svaku površinu, uključuje prvi list papira u dodiru sa slojem i drugi list papira stavljen iznad rečenog prvog lista, rečeni postupak uključuje prešanje. "Čvrstoća pokrovne ploče" određena je u skladu s Europskom normom 311, naslova "Površinska čvrstoća". The invention relates to a process for covering a chipboard board, in particular a board with a thickness of 10 to 40 mm, and which has two main opposite surface layers with a surface density above 800 kg/m3 and a cover board strength of 8 to 12 kg/cm2, said covering, for each surface, includes a first sheet of paper in contact with the layer and a second sheet of paper placed above said first sheet, said process including pressing. The "strength of the cover plate" is determined in accordance with the European standard 311, entitled "Surface strength".
Drugim riječima, izum se odnosi na pokrivanje daske od iverice s papirom impregniranim s modificiranom aminoplastičnom smolom; prekrivanje se provodi kratkim ciklusom na liniji za prešanje pod srednjim pritiskom. In other words, the invention relates to covering a chipboard board with paper impregnated with a modified aminoplastic resin; the coating is carried out in a short cycle on a pressing line under medium pressure.
Cilj izuma je dati postupak po kojem je prekrivena daska prikladna za podvrgavanje postupku naknadnog oblikovanja tijekom kojeg se pokrovni papir može savinuti, s odgovarajućom napravom, preko rubova daske, s minimalnim radijusom zakrivljenosti od 4 mm, a bez nastanka napuklina na površini prekrivene daske. The aim of the invention is to provide a process by which the covered board is suitable for undergoing a subsequent shaping process during which the covering paper can be bent, with a suitable device, over the edges of the board, with a minimum radius of curvature of 4 mm, and without the appearance of cracks on the surface of the covered board.
Taj cilj postignut je postupkom tipa opisanog na početku koji je naznačen time da uključuje slijedeće stupnjeve: (A) stavljanje prvog lista papira težine između 60 i 180 g/m2; (B) stavljanje prve vodene smole sa sadržajem od 30 do 60 mas. % urea-melamin-formaldehidne smole niskog stupnja kondenzacije kao čvrste tvari; od 4 do 10 mas. % plastifikatora iz porodice sulfonamida ili poliglikola; od 0,3 do 1 mas. % sredstva za vlaženje iz skupine koju čine površinski aktivne tvari; od 0,5 do 3 mas. % kiselog katalizatora; od 0,5 do 1 mas. % sredstva za odvajanje od kalupa; (C) impregnaciju rečenog prvog lista s rečenom vodenom smolom sve dok rečeni prvi listovi prime sadržaj čvrste smole od 45 do 60 mas. % i sadržaj hlapljivog od 5 do 7 mas.; (D) stavljanje drugog lista papira; (E) stavljanje druge vodene smole koja ima od 30 do 60 mas. % urea-melamin-formaldehidne smole niskog stupnja kondenzacije kao čvrste tvari, od 0 do 8 mas. % plastifikatora iz porodice sulfonamida ili poliglikola; od 0,1 do 1 mas. % sredstva za vlaženje iz porodice površinski aktivnih tvari; od 0,2 do 2 mas. % kiselog katalizatora; i od 0,1 do 1 mas. % sredstva za odvajanje od kalupa; (F) ompregnaciju rečenog drugog lista s rečenom drugom vodenom smolom, sve dok rečeni drugi listovi prime sadržaj čvrste smole od 30 do 60 mas. % i sadržaj hlapljivog od 5 do 7 mas.; (G) oblikovanje cjeline koja uključuje uzastopce prvi list papira, drugi list papira, dasku, drugi list papira i prvi list papira; i (H) prešanje rečene cjeline, primjenom specifičnog pritiska u rasponu od 20 do 30 kg/cm2, površina prešanja u dodiru sa cjelinom ima temperaturu u rasponu od 130 do 180°C tijekom vremena u rasponu od 30 do 80 sekundi. This object is achieved by a process of the type described at the outset, which is indicated to include the following steps: (A) placing a first sheet of paper weighing between 60 and 180 g/m 2 ; (B) placing the first aqueous resin with a content of 30 to 60 wt. % urea-melamine-formaldehyde resin of low degree of condensation as solids; from 4 to 10 wt. % of plasticizers from the sulfonamide or polyglycol family; from 0.3 to 1 wt. % wetting agents from the group consisting of surfactants; from 0.5 to 3 wt. % acid catalyst; from 0.5 to 1 wt. % release agent from the mold; (C) impregnation of said first sheet with said aqueous resin until said first sheets receive a solid resin content of 45 to 60 wt. % and volatile content from 5 to 7 wt.; (D) placing a second sheet of paper; (E) adding another aqueous resin having from 30 to 60 wt. % urea-melamine-formaldehyde resin of low degree of condensation as a solid substance, from 0 to 8 wt. % of plasticizers from the sulfonamide or polyglycol family; from 0.1 to 1 wt. % wetting agents from the family of surfactants; from 0.2 to 2 wt. % acid catalyst; and from 0.1 to 1 wt. % release agent from the mold; (F) impregnation of said second sheet with said second aqueous resin, until said second sheets receive a solid resin content of 30 to 60 wt. % and volatile content from 5 to 7 wt.; (G) forming a unit that includes in succession the first sheet of paper, the second sheet of paper, the board, the second sheet of paper, and the first sheet of paper; and (H) pressing said unit, applying a specific pressure in the range of 20 to 30 kg/cm2, the pressing surface in contact with the unit having a temperature in the range of 130 to 180°C for a time in the range of 30 to 80 seconds.
Rečeni plastifikator ponajprije je o-p-toluen sulfonamid ili dietilen glikol; rečeno sredstvo za vlaženje je alkil nonil fenol; rečeni kiseli katalizator je kisela hidrolitička sol organske kiseline i rečeno sredstvo za odvajanje od kalupa je vodena silikonska emulzija. Said plasticizer is preferably o-p-toluene sulfonamide or diethylene glycol; said wetting agent is alkyl nonyl phenol; said acid catalyst is an acid hydrolytic salt of an organic acid and said release agent is an aqueous silicone emulsion.
Izum pruža prednosti pred sadašnjim postupcima naknadnog prekrivanja daske. The invention provides advantages over the current methods of subsequent covering of the board.
Jedna prednost je u izravnoj, jednostavnoj izradi proizvoda koji se može naknadno oblikovati stavljanjem impregniranog papira na dasku u kratkom ciklusu, na prešama srednjeg pritiska, umjesto da se najprije izradi pokrov s impregniranim papirom dugačkim ciklusom na prešama visokog pritiska i zatim se rečeni pokrov nalijepi na osnovnu dasku na drugoj preši. One advantage is the direct, simple production of a product that can be post-formed by placing the impregnated paper on the board in a short cycle on medium pressure presses, rather than first making a cover with impregnated paper in a long cycle on high pressure presses and then applying said cover to the base board on the second press.
Druga prednost dobivena izumom je to, da proizvod, koji se može naknadno oblikovati, dobiven pomoću papirnog pokrova mnogo niže opće težine od onog upotrijebljenog za pokrove dugog ciklusa pod visokim pritiskom i upotrebom aminoplastične umjesto fenolne smole. Another advantage obtained by the invention is that the product, which can be postformed, is obtained using a paper cover of a much lower overall weight than that used for long cycle covers under high pressure and using an aminoplastic instead of a phenolic resin.
Kako je gore utvrđeno, proizvod ovog izuma dobiven je prekrivanjem ploče od iverice odgovarajućih svojstava površine, osobito gustoće njenog površinskog sloja i čvrstoće površinskog pokrova. As stated above, the product of this invention is obtained by covering a particle board with suitable surface properties, especially the density of its surface layer and the strength of the surface covering.
Prekrivanje mora uključiti četiri sloja impregniranog papira po daski, dva sa svake strane, s listovima koji se stavljaju izravno na površinu daske koji su različiti od vanjskog lista koji se stavlja preko kalupa. The covering must include four layers of impregnated paper per board, two on each side, with sheets applied directly to the surface of the board that are different from the outer sheet applied over the mold.
Listovi papira stavljeni izravno na dasku moraju imati masu od 60 do 180 g po kvadratnom metru i moraju biti impregnirani s urea-melamin-formaldehidnom smolom niskog stupnja kondenzacije, ali koja se može dugo skladištiti, modificiranom s platifikatorima iz porodice poliglikola i sulfonamida. Sheets of paper placed directly on the board must have a mass of 60 to 180 g per square meter and must be impregnated with a urea-melamine-formaldehyde resin with a low degree of condensation, but which can be stored for a long time, modified with platifiers from the polyglycol and sulfonamide family.
Vanjski listovi papira koji se stavljaju na prethodni sloj obično su ukrasni papiri svih vrsta za visoki i niski pritisak, za dugi i kratki ciklus prekrivanja, ali za ovu primjenu oni moraju biti impregnirani s urea-melamin-formaldehidnom smolom niskog stupnja kondenzacije, koja ima dugi vijek skladištenja, modificiranom s plastifikatorom iz porodice poliglikola ili sulfonamida. The outer sheets of paper placed on the previous layer are usually decorative papers of all types for high and low pressure, for long and short covering cycles, but for this application they must be impregnated with urea-melamine-formaldehyde resin with a low degree of condensation, which has a long shelf life, modified with a plasticizer from the polyglycol or sulfonamide family.
Pokrov koji se može naknadno oblikovati prema ovom izumu proizveden u kratkom ciklusu, s prešom srednjeg pritiska primjenom prikladnog tlaka i temperature na cjelinu oblikovanu od iverice između četiri impregnirana papira, kako je gore opisano, dva na jednoj strani i druga dva na drugoj strani, papiri u dodiru s ivericom su različiti od vanjskih papira. A post-formable cover according to the present invention is produced in a short cycle, with a medium pressure press applying the appropriate pressure and temperature to a chipboard molded unit between four impregnated papers, as described above, two on one side and the other two on the other side, papers in contact with chipboard, they are different from outer papers.
