Description

DK 151954BDK 151954B

Den foreliggende opfindelse angår en fremgangsmåde til fremstilling af et let bygningsmateriale, især et ubrændbart byggelegeme med gode varmeisoleringsegenskaber, som yderligere er godt lydisolerende, ved varmepresning af uorganiske ekspanderede materialer og et hærdeligt bindemiddel, som især indeholder phenolharpiks ogThe present invention relates to a process for producing a lightweight building material, in particular a non-combustible building body with good thermal insulation properties, which is further well sound insulating, by heat-pressing inorganic expanded materials and a curable binder containing, in particular, phenolic resin and

carbamidharpiks.urea.

Det er kendt at anvende harpiksblandinger eller blandingsharpikser, som indeholder en phenolharpiks og en urinstofkomponent i harpiksbundne uorganiske materialer, især i byggematerialer.It is known to use resin blends or blend resins which contain a phenolic resin and a urea component in resin bonded inorganic materials, especially in building materials.

Fra fransk patentskrift nr. 1421400 kendes således en fremgangsmåde til fremstilling af en byggeplade, hvor man på opblæret perlit sprøjter et hærdeligt bindemiddel, som er phenolharpiks og/eller aminoharpiks, placerer den derved dannede pasta i en form og opvarmer pastaen i formen under svagt tryk, hvorved byggepladen dannes.Thus, from French Patent Specification No. 1421400, a method of making a building plate is known in which a curable binder which is a phenolic resin and / or amino resin is sprayed onto the blighted pearlite, places the thus formed paste in a mold and heats the paste in the mold under low pressure. , whereby the building plate is formed.

1515

Fremgangsmåden ifølge opfindelsen til fremstilling af et let byggemateriale er ejendommelig ved, at granulat af ekspanderet vermiculit under omrøring sprøjtes med det i vandholdig opløsning foreliggende bindemiddel, og det på denne måde besprøjtede granulat komprimeres ved stuetemperatur i en fra pressen adskilt forpresningsanord-2Q ning til en transporterbar pressekage, derefter indføres i pressen og endelig på i og for sig kendt måde varmepresses og hærdes. Det fra formen udtagne granulat har på grund af forkomprimeringen en sådan styrke, at der dannes en stabil pressekage, som uden særlige transportmidler såsom transportbånd og uden at blive ridset kan bringes direkte ind i pressen.The process of the invention for the preparation of a lightweight building material is characterized by spraying expanded vermiculite granules with the binder present in aqueous solution and compressing the granules thus sprayed at room temperature in a press-separating device 2Q to a transportable press cake, then introduced into the press and finally heat-pressed and cured in a manner known per se. Due to the precompression, the granules taken from the mold have such strength that a stable press cake is formed which can be brought directly into the press without special means of transport such as conveyor belts and without being scratched.

Fremgangsmåden ifølge den foreliggende opfindelse adskiller sig således fra fremgangsmåden i henhold til fransk patent nr. 1421400 ved, at der ved stuetemperatur foregår en forkomprimering, hvorved der fremstilles en let transporterbar pressekage, der derefter komprimeres og hærdes på normal vis. Fremgangsmåden ifølge opfindelsen adskiller sig yderligere fra den fra fransk patent nr. 1421400 kendte fremgangsmå-30 de ved, at der i stedet for opblæret perlit anvendes et granulat af ekspanderet vermiculit. Det har vist sig, at der ved anvendelse af opblæret perlit påført bindemiddel ved forkomprimering ved stuetemperatur ikke kan fremstilles en let transporterbar pressekage, som det er tilfældet ved anvendelse af vermiculit.Thus, the process of the present invention differs from the process of French Patent No. 1421400 in that at room temperature a precompression takes place, thereby producing an easily transportable press cake which is then compressed and cured in the normal manner. The process according to the invention differs further from the method known from French Patent No. 1421400 in that, instead of inflated perlite, an expanded vermiculite granulate is used. It has been found that by using inflated perlite applied binder at room temperature precompression, an easily transportable press cake, as is the case with vermiculite, cannot be produced.

35 Det er ifølge opfindelsen særlig hensigtsmæssigt, at varmepresningen udføres i en ved hjælp af en højfrekvensstrøm opvarmet presse.35 According to the invention, it is particularly convenient that the heat pressing is carried out in a press heated by a high frequency current.

Ved en fordelagtig udførelsesform for fremgangsmåden ifølge opfindelsen indføres der under sprøjtningen af granulatet med bindemidlet forstærknings- eller armeringselementer. Som forstærknings- eller armeringselementer egner sig især f.eks. glasfibre og glastråde.In an advantageous embodiment of the method according to the invention, during the spraying of the granulate with the binder reinforcing or reinforcing elements are introduced. Particularly suitable as reinforcing or reinforcing elements, e.g. fiberglass and glass wires.

En fordel ved den foreliggende opfindelse er, at den forkomprimerede pressekage kan presses med bindemiddelbefugtede dækark. Ved en sådan flerlagsopbygning kan der opnås en forhøjelse af det fremstillede bygningsmateriales mekaniske styrke.An advantage of the present invention is that the precompressed press cake can be pressed with binder wetted cover sheets. With such a multilayer structure, an increase in the mechanical strength of the manufactured building material can be achieved.

Opfindelsen belyses nærmere ved følgende eksempler: j 10 i i EKSEMPEL 1 600 liter (50 kg) vermiculit med partikelstørrelse 0,5-3 mm blandes i en fritfaldblander ved påsprøjtning med 12 liter af en 70%‘s vandig harpiksblanding bestående af 85 15 ! molprocent phenolformaldehydharpiks og 15 molprocent urinstofformaldehydharpiks, således at partiklerne af det opblærede glimmer befugtes ensartet. Det således fremstillede harpiksovertrukne granulat komprimeres i en egnet ikke-opvarmet forpres-seindretning ensartet ved et tryk på ca. 1,5 kp/cm2 til ca. 50% af sit oprindelige rysterumfang, hvorved der fås et transportabelt formlegeme. Dette formlegeme udhærdes 20 derefter i en med højfrekvensopvarmning og/eller termisk opvarmning udstyret presse under samtidig medpresning af ensidigt harpiksbelagte dækplader af kraftpapir ved et tryk på 2-3 kp/cm2 og en pressetemperatur på 150-170°C. Formpresselegemet udtages ' varmt fra formen og skæres til det ønskede format.The invention is further illustrated by the following examples: in Example 1 600 liters (50 kg) of 0.5-3 mm particle size vermiculite are mixed in a free fall mixer by spraying with 12 liters of a 70% aqueous resin mixture consisting of 85 15! mole percent phenol formaldehyde resin and 15 mole percent urea formaldehyde resin so that the particles of the bloated mica are uniformly wetted. The resin-coated granules thus prepared are compressed uniformly in a suitable non-heated prepressing device at a pressure of approx. 1.5 kp / cm2 to approx. 50% of its original shaking volume, giving a transportable mold body. This mold body is then cured in a press equipped with high frequency heating and / or thermal heating under the co-pressing of unilateral resin coated kraft paper sheets at a pressure of 2-3 kp / cm 2 and a press temperature of 150-170 ° C. The molding body is removed from the mold hot and cut to the desired size.

j 25 Ved prøvningen af brændbarheden optræder ingen kvælende eller brændbare dampe eller gasser, materialet gløder under flammeindvirkning svarende til den herskende temperatur, men efter fjernelse af flammen kan der ikke iagttages nogen efterforbræn-ding.25 In the test of flammability no suffocating or combustible vapors or gases occur, the material glows under flame action corresponding to the prevailing temperature, but no post-combustion can be observed after removal of the flame.
