Description
Fremgangsmåte til å forbedre hårde trefiberplaters målbarhet. Method of improving hard wood fiberboard measurability.
Foreliggende oppfinnelse angår en The present invention relates to a
fremgangsmåte ved fremstilling av hårde, herdede trefiberplater der et våtark underkastes pressing og tørking, samt at den frembragte plate derefter utsettes for var-meherding. method for the production of hard, hardened wood fiber boards where a wet sheet is subjected to pressing and drying, and that the produced board is then subjected to heat hardening.
Hårde, herdede trefiberplater anvendes Hard, hardened wood fiber boards are used
i stor utstrekning som bekledningsmateriale både innvendig og utvendig og flatebehand-les til dette bruk ofte ved maling eller lak-kering. Dette er en forholdsvis dyr flatebehandling og prisen for en første-klasses oljemaling av platen er betydelig høyere enn' platens pris. Malingsomkostningene blir derved uforholdsmessig høy i forhold til total-prisen, og det er derfor et helt naturlig ønskemål å sette ned prisen på malingen. En omstendighet som i vesentlig grad bidrar til den høye malingsprisen er at store mengder maling suges inn i platen p.g.a. dennes porøsitet. Dette øker dels malingforbruket, dels antall strøk som trenges for en tilfredsstillende flatebehandling. to a large extent as cladding material both inside and outside and is surface-treated for this use, often by painting or varnishing. This is a relatively expensive surface treatment and the price for a first-class oil painting of the plate is considerably higher than the plate's price. The painting costs are therefore disproportionately high in relation to the total price, and it is therefore a completely natural desire to reduce the price of the paint. A circumstance that significantly contributes to the high paint price is that large amounts of paint are sucked into the plate due to its porosity. This partly increases paint consumption and partly the number of coats needed for a satisfactory surface treatment.
Det har nu vist seg at denne ulempen It has now been shown that this disadvantage
kan elimineres ved en spesiell behandlings-metode. Denne metode kjennetegnes ifølge oppfinnelsen ved at det på platens flate før varmeherdingen anbringes en blanding som består av en bare lite flyktig herdbar organisk væske og et inert fyllmiddel, idet innholdet av inert fyllmiddel oppgår til 20—100 pst. regnet på mengden herdbar organisk væske, og at det derefter utføres en så kraftig mekanisk bearbeidelse av flaten at dennes porer fylles med en blanding can be eliminated by a special treatment method. According to the invention, this method is characterized by the fact that a mixture consisting of a slightly volatile curable organic liquid and an inert filler is placed on the plate's surface before the heat curing, with the content of inert filler being 20-100 per cent based on the amount of curable organic liquid, and that the surface is then subjected to such vigorous mechanical processing that its pores are filled with a mixture
av inert fyllmiddel og herdbar organisk væske. of inert filler and curable organic liquid.
Det vesentlige trekket ved fremgangsmåten ifølge oppfinnelsen består i at be-handlingen av trefiberplatene utføres mel-lom pressingen og varmeherdingen. The essential feature of the method according to the invention is that the treatment of the wood fiber boards is carried out between the pressing and the heat curing.
Det middel som brukes ved ovenstående behandling er ikke noe nytt. Det har blant annet tidligere vært brukt for behandling av treflater som forberedelse for maling. Å bruke det sammen for behandling av herdede trefiberplater har allikevel tidligere ikke vært beskrevet. The agent used in the above treatment is nothing new. Among other things, it has previously been used to treat wooden surfaces as preparation for painting. However, using it together for the treatment of hardened wood fiber boards has not previously been described.
En lignende fremgangsmåte er tidligere kjent (se U.S. patent nr. 2 176 981). Her dreier det seg dog om flatebehandling av porøse fiberplater. Ved slike utføres be-handlingen med en maling som består av en vannholdig oppløsning eller suspensjon som inneholder et bindemiddel såsom kasein eller stivelse. Behandlingskomposisjo-nen kan, men behøver ikke, inneholde pigment eller fyllmiddel. Den kan også inneholde en tørkende olje i begrenset mengde, idet hensikten med tilsettingen er å forbedre den ferdige platens vannavvisende egenskaper. Den ifølge oppfinnelsen an-vendte flatebehandlingsblanding derimot skiller seg vesentlig fra den som anvendes ifølge det nevnte patent. Den har således ikke noe som helst behov for den for den kjente blandingen viktige bestanddelen bindemiddel av typen stivelse eller kasein eller av vann. For den overflateblanding som brukes ifølge oppfinnelsen er det vesentlig at den skal inneholde et fyllmiddel, mens denne bestanddel er av mindre betyd-ning ved den kjente behandling av porøse fiberplater. Fremgangsmåten ifølge oppfinnelsen kan utføres industrielt ved pro-duksjonsstedet for trefiberplatene. Det er således mer rasjonelt enn om man skulle velge å anbringe behandlingsmiddelet på bruksstedet for platene. A similar method is previously known (see U.S. Patent No. 2,176,981). However, this concerns the surface treatment of porous fiber boards. In such cases, the treatment is carried out with a paint consisting of an aqueous solution or suspension containing a binder such as casein or starch. The treatment composition may, but need not, contain pigment or filler. It can also contain a limited amount of drying oil, as the purpose of the addition is to improve the water-repellent properties of the finished board. The surface treatment mixture used according to the invention, on the other hand, differs significantly from that used according to the aforementioned patent. It thus has no need whatsoever for the important component of the known mixture, binder of the type starch or casein or water. For the surface mixture used according to the invention, it is essential that it should contain a filler, while this component is of minor importance in the known treatment of porous fiber boards. The method according to the invention can be carried out industrially at the production site for the wood fiber boards. It is thus more rational than if one were to choose to place the treatment agent at the place of use for the plates.
En trefiberplate som er behandlet iføl-ge oppfinnelsen har avgjort bedre slipbar-het enn en som er behandlet på samme måte efter herdingen. Denne påstand be-kreftes med følgende forsøk: Ved forsøkene er det benyttet standard-plater som er blitt impregnert med forskjellige herdbare organiske væsker og med forskjellige mengder fyllmiddel, hvor-etter slipbarheten ble bestemt efter en standard behandling med slipepapir nr. 320 «international standard», ut fra klebelig-heten på slipestøvet A og iakttatt gjentet-ting av slipepapiret B, idet disse egenskaper ble vurdert efter en bedømmelsesskala som omfattet karakterene 1 til 5. Tre forskjellige serier av forsøk ble utført, nemlig 1. behandling av herdede plater med herdbar organisk væske uten efterfølgende varmebehandling, 2. behandling som ovenfor, men med efterfølgende varmebehandling (i stråle-ovn), og 3. behandling av presset plate med herdbar organisk væske og derefter føl-gende herding av platene (ifølge oppfinnelsen) . A wood fiber board that has been treated according to the invention has decidedly better sandability than one that has been treated in the same way after curing. This claim is confirmed with the following experiments: In the experiments, standard plates were used which had been impregnated with different hardenable organic liquids and with different amounts of filler, after which the grindability was determined according to a standard treatment with sanding paper no. 320 "international standard", based on the stickiness of the sanding dust A and observed resealing of the sanding paper B, as these properties were assessed according to a rating scale that included the grades 1 to 5. Three different series of tests were carried out, namely 1. treatment of hardened plates with curable organic liquid without subsequent heat treatment, 2. treatment as above, but with subsequent heat treatment (in a beam furnace), and 3. treatment of pressed plate with curable organic liquid and then following hardening of the plates (according to the invention) .
Følgende resultat ble oppnådd The following result was obtained
Resultatet i kolonnene som angår plater behandlet ifølge oppfinnelsen er således overlegne. The results in the columns relating to plates treated according to the invention are thus superior.
Fyllmiddelet bør være finkornet og kan hensiktsmessig utgjøres av et pigment. Eks. på slike som kan brukes med utmerket resultat er titandioxyd eller kritt. Som ytterligere eks. på fyllmiddel kan nevnes kaolin, feltspat, aluminiumpulver og kvarts. Fyllmiddelet alene gir imidlertid ikke den øns-kede effekt, men denne fremtrer først om det brukes i forbindelse med den herdbare organiske væsken. Sannsynligvis forholder det seg slik at kornene av fyllmiddelet som trenger inn i porene i platens flate må bindes der av et væskesjikt som også full-byrder tetningen av porene. The filler should be fine-grained and can suitably consist of a pigment. Ex. on such that can be used with excellent results are titanium dioxide or chalk. As a further example fillers include kaolin, feldspar, aluminum powder and quartz. However, the filler alone does not produce the desired effect, but this only appears if it is used in conjunction with the hardenable organic liquid. It is probably the case that the grains of the filler which penetrate into the pores in the plate's surface must be bound there by a layer of liquid which also fully burdens the sealing of the pores.
Som eks. på hensiktsmessige herdbare organiske væsker kan nevnes linolje, tallolje, modifisert tallolje, kinesisk treolje, soyabønneolje og standolje. Istedet for en tørkende olje kan man bruke andre organiske forbindelser av lignende typer, såsom alkyder, andre herdbare organiske væsker, såsom styren og vinyltoluen eller lakker, såsom celluloseacetat eller nitro-cellulose. As e.g. Suitable curable organic liquids include linseed oil, tall oil, modified tall oil, Chinese wood oil, soybean oil and tallow oil. Instead of a drying oil, other organic compounds of similar types can be used, such as alkyds, other hardenable organic liquids, such as styrene and vinyltoluene or lacquers, such as cellulose acetate or nitro-cellulose.
Som allerede angitt er det nødvendig at blandingen av fyllmiddel og herdbar væske arbeides inn i trefiberplatens flate ved en kraftig mekanisk bearbeidelse for at den ønskelige minskningen av malingsfpr-bruket skal inntre. Under alle omstendig-heter skulle fyllmiddelet komme til å ligge tilbake på platens flate, og det er først ved den mekaniske bearbeidelsen at fyllmiddelet kan bringes til å trenge inn i porene. As already indicated, it is necessary that the mixture of filler and hardenable liquid is worked into the surface of the wood fiber board by a strong mechanical processing in order for the desired reduction in the use of paint to occur. Under all circumstances, the filler should come to lie back on the plate's surface, and it is only during the mechanical processing that the filler can be made to penetrate the pores.
Kornstørrelsen på fyllmiddelet bør passe til porestørrelsen i platen, hvilket innebærer at diameteren på kornene bør være omkring 1—10j.i. For øvrig synes egen-skapene av fyllmiddelet ikke å ha noen be-tydning for resultatet. Den mengde av be-handlingsmiddel som trenges å innarbeides i platen beror på dennes egenskaper, f. eks. størrelsen av de fibre som inngår i flaten. Normale verdier er 20—25 g pr. m2 og man skulle ikke i noe fall behøve å bruke mer enn 50 g pr. m2. The grain size of the filler should match the pore size in the plate, which means that the diameter of the grains should be around 1-10j.i. Otherwise, the properties of the filler do not seem to have any significance for the result. The amount of treatment agent that needs to be incorporated into the plate depends on its properties, e.g. the size of the fibers included in the surface. Normal values are 20-25 g per m2 and you should in no case need to use more than 50 g per m2.
Blandingen av herdbar væske og fyllmiddel strykes hensiktsmessig ut på flaten i større mengde enn det som skal arbeides inn i platen, hvorefter overskuddet strykes av. Denne fremgangsmåte er hensiktsmessig p.g.a. vanskeligheten ved over en flate jevnt å fordele så små mengder som de som skal brukes. Den del av blandingen som lig-ger igjen på platens flate arbeides derefter inn i denne ved kraftig bearbeiding, f. eks. av roterende børster. The mixture of hardenable liquid and filler is appropriately spread on the surface in a larger quantity than is to be worked into the plate, after which the excess is wiped off. This method is appropriate because the difficulty of evenly distributing over a surface such small quantities as those to be used. The part of the mixture that remains on the plate's surface is then worked into it by vigorous processing, e.g. of rotating brushes.
I den flatebehandlede platen er fyllmiddelet arbeidet inn i flatens porer, mens flatefibrene og flåtestrukturen forblir ube-rørt og er nu overtrukket med tynt lag av den tørkede eller herdede oljen som utgjør et godt underlag for den følgende maling og gir en god vedhefting av malingen. In the surface-treated plate, the filler is worked into the pores of the surface, while the surface fibers and the raft structure remain untouched and are now coated with a thin layer of the dried or hardened oil which forms a good base for the following paint and provides good adhesion of the paint.
En ytterligere fordel som oppnås ifølge oppfinnelsen er at flatebehandlingen fore-bygger såkalt fiberreising i flaten av tre-fiberplaten. Ved at porene er tettet til har fibrene når malingen tilføres tydeligvis mistet evnen til å suge opp oppløsningsmid-del og svelle på vanlig måte, hvilket med-virker til å gi platen en planere flate. A further advantage achieved according to the invention is that the surface treatment prevents so-called fiber raising in the surface of the wood fiber board. As the pores are sealed, when the paint is added, the fibers have clearly lost the ability to absorb solvent and swell in the usual way, which contributes to giving the plate a flatter surface.
Ved flatebehandlingen ifølge oppfinnelsen kan maleomkostningene for trefiber-platen bringes ned i meget vesentlig grad. En sammenlikning av maling på en således behandlet plate og førsteklasses oljemaling på ubehandlet plate gir det resultat at man i det første tilfelle foruten grunning kan spare inn en eller to mellomstrøk. Det som her bestemmer malingforbruket ved malingen er nærmest malingens dekkeevne. Besparelsen ved flatebehandling ifølge oppfinnelsen blir derfor betydelig og langt større enn prisen på selve flatebehandlingen. With the surface treatment according to the invention, the painting costs for the wood fiber board can be brought down to a very significant extent. A comparison of paint on a board thus treated and first-class oil paint on an untreated board gives the result that in the first case, in addition to priming, one or two intermediate coats can be saved. What determines the paint consumption during the painting is mostly the paint's covering ability. The savings from surface treatment according to the invention are therefore significant and far greater than the price of the surface treatment itself.
