Description
Fremgangsmåte for fremstilling av formstykker av seigharde skumgranulater med lukkete celler bundet med bindemiddel. Process for the production of shaped pieces of tough foam granules with closed cells bound with a binder.
Denne oppfinnelse vedrører en fremgangsmåte for fremstilling av formstykker av seigharde skumgranulater med lukkete celler, som er bundet sammen med bindemiddel. This invention relates to a method for producing molded pieces of tough foam granules with closed cells, which are bound together with a binder.
Slike, etter oppfinnelsen fremstilte formstykker, har en god slag- og støtfasthet og dempning og egner seg, særlig i stav-form, til avstandsholdere og montasjehoder i betongbygg. Etter-som disse produkter, p.g.a. av sin seigelastisitet, også kan spikres godt, kan de brukes tids- og arbeidsbesparende i direkte-montasjen. De er vanntette mot gjennomsivende vann, råtner ikke og er hydrolysefaste. Such shaped pieces, manufactured according to the invention, have good impact and shock resistance and damping and are suitable, especially in rod form, for spacers and assembly heads in concrete buildings. As these products, due to due to their ductility, can also be nailed well, they can be used to save time and labor in direct assembly. They are waterproof against seeping water, do not rot and are resistant to hydrolysis.
Formstykkene etter foreliggende oppfinnelse fremstilles slik at det blandes seigharde skumgranulater med lukkede celler med en kornstørrelse på 10 til 12 mm sammen med et bindemiddel av middels eller lav viskositet i et volums-blandingsforhold mellom granulat og bindemiddel på 55:1 til 45:1, og blandingen herdes ut ved temperaturer mellom 60 og 80°C og ved et begynnelsestrykk på 5 yil 8 bar. The moldings according to the present invention are produced in such a way that tough foam granules with closed cells with a grain size of 10 to 12 mm are mixed together with a binder of medium or low viscosity in a volume mixing ratio between granules and binder of 55:1 to 45:1, and the mixture hardens at temperatures between 60 and 80°C and at an initial pressure of 5 yil 8 bar.
Som seighardt skumgranulat med lukkede celler brukes for-trinnsvis polyvinylklorid, men også granulater av andre seig-elastiske materialer, som f.eks. polyolefiner, etc. kan komme til anvendelse. Polyvinyl chloride is preferably used as tough foam granules with closed cells, but also granules of other tough-elastic materials, such as e.g. polyolefins, etc. can be used.
Som bindemiddel brukes det varmeherdende eller ved rom-temperatur herdende harpikser av middels eller lav viskositet. Slike er polyuretaner, epoksyharpikser, polymetakrylharpikser, men først og fremst umettede polyesterharpikser. Heat-curing or room-temperature curing resins of medium or low viscosity are used as binders. Such are polyurethanes, epoxy resins, polymethacrylic resins, but primarily unsaturated polyester resins.
Til denne blanding av hardskumgranulat og bindemiddel kan tilsettes uorganiske fyllstoffer eller pigmenter, f.eks. glass-eller asbestfiber, sement, kalsiumkarbonater, bauxitt, oker, etc. Disse tilsetningsstoffer tjener både farvegivning og for-bedring av hefteegenskapene på betong eller mørtel. Ved valg av komprimering (anvendt trykk) ved utherdingen og størrelsen på granulatet kan en stille inn den spesifikke vekt av det ferdige formstykke. Velger en et trykk på 6 bar og en korn-størrelse på 10 til 15 mm, så får en produkter med en densitet på 580 - 590 kg/m<3>. Inorganic fillers or pigments can be added to this mixture of hard foam granules and binder, e.g. glass or asbestos fibres, cement, calcium carbonates, bauxite, ochre, etc. These additives serve both to give color and to improve the adhesion properties of concrete or mortar. By choosing compression (applied pressure) during curing and the size of the granulate, the specific weight of the finished mold can be set. If you choose a pressure of 6 bar and a grain size of 10 to 15 mm, you get products with a density of 580 - 590 kg/m<3>.
Med det ovennevnte trykk menes begynnelsestrykket som inn-stilles ved utherdingen. Under herdingen reduseres trykket av By the above-mentioned pressure is meant the initial pressure that is set during curing. During curing, the pressure is reduced
seg selv.itself.
Utherdingen skjer mest hensiktsmessig i stempelpresser. Pressen smøres helst med et slippmiddel som gjør uttaket av produktet lettere. Curing takes place most appropriately in piston presses. The press should preferably be lubricated with a release agent that makes the removal of the product easier.
