Description
Przedmiotem wynalazku jest furanowa masa formierska i rdzeniowa, stosowana przy wytwa¬ rzaniu form i rdzeni odlewniczych.The subject of the invention is furan mass molding and core, used in the production of casting molds and foundry cores.
Znane sa masy formierskie i rdzeniowe zawie¬ rajace jako spoiwo zywice furanowe modyfiko¬ wane styrenem i/lub zawierajace grupy metylo- lowe w pozycji |5 — pierscienia furanowego, utwardzone kompozycja katalityczna na bazie kwasu p-tolueno-sulfonowego z dodatkiem ketonu cykloalifatycznego. Znane masy formierskie i rdze¬ niowe na bazie zywic furanowych modyfikowa¬ nych styrenem i/lub zawierajace grupy metylolo- we w pozycji j}-pierscienia furanowego, utwardza¬ ne z zastosowaniem kompozycji katalitycznej za¬ wierajacej kwas p-tpluenosulfonowy oraz keton cykloalifatyczny wykazuja duza wytrzymalosc me¬ chaniczna i reaktywnosc pozwalajaca na stosun¬ kowo szybkie wytwarzanie form i rdzeni.Molding and core sands are known skimmers as a binder furan resins modified styrene and / or containing methyl groups lowe in position | 5 - furan ring, cured catalytic composition based on p-toluene sulfonic acid with the addition of ketone cycloaliphatic. Known molding compositions and cores based on furan resins modified containing styrene and / or containing methylol groups we in position j} - furan ring, harden with the use of a catalytic composition containing p-tpluenesulfonic acid and a ketone cycloaliphatic exhibits high metal strength chanical and reactivity allowing for intercourse quick production of molds and cores.
Zmechanizowane procesy formierskie wymagaja bardzo krótkich czasów wstepnego wiazania — po uplywie 10—12 minut wytrzymalosc mechaniczna masy musi byc wystarczajaca do wyjecia nieuszko¬ dzonego rdzenia ze skrzynki formierskiej. Przy¬ spieszanie utwardzania zywicy na drodze powiek¬ szenia ilosci dodanego katalizatora nie daje re¬ zultatów. Wraz ze skróceniem czasu wstepnego wiazania, znacznemu ograniczeniu ulega zywot¬ nosc masy, co powoduje trudnosci w formowaniu rdzeni.Mechanized molding processes require very short initial setting times - after after 10-12 minutes mechanical strength the mass must be sufficient to remove it a knitted core from a molding box. By hastening the hardening of the resin in the way of the eyelids increasing the amount of added catalyst did not give a residual results. Along with reducing the lead-in time binding, the viability is significantly reduced weight bearing, which causes difficulties in forming cores.
Celem wynalazku jest usuniecie powyzszej nie- dogodnosci i uzyskanie masy formierskiej o sto¬ sunku czasu wstepnego wiazania do okresu zywot¬ nosci odpowiadajacym wymogom procesów zme¬ chanizowanych, to znaczy od 1,0 do 2,0.The aim of the invention is to eliminate the above-mentioned Convenience and obtaining molding mass by a hundred the ratio of the initial setting time to the pot life suitable for change processes canized, that is, from 1.0 to 2.0.
Okazalo sie, iz wymagana relacje miedzy cza¬ sem wstepnego wiazania, a okresem zywotnosci masy formierskiej i rdzeniowej na bazie zywicy furanowej modyfikowanej styrenem i/lub zawie¬ rajacej grupy metylolowe w pozycji 0 pierscienia furanowego, utwardzanej katalizatorem zawiera¬ jacym aktywator cykloalifatyczny, mozna uzyskac przez dodatek Y_aminopropylotrójetoksykrzemome- . tanu w ilosci 0,001—0,05% w stosunku do masy rdzeniowej.It turned out that the required relationship between time the initial binding semester and the life span resin-based molding and core sand furan modified with styrene and / or suspended the methylol group at the O-position of the ring furan, hardened with a catalyst, contains by a cycloaliphatic activator, can be obtained by the addition of Y_aminopropyltriethoxy silicon- . of tan in an amount of 0.001-0.05% by weight spinal.
Y-aminopropylotrójetoksykrzemometan wprowa¬ dzony w ilosci 0,1—2,0% -wagowych w stosunku do zywicy do masy formierskiej i rdzeniowej zmienia przebieg wstepnego etapu utwardzania zywicy modyfikowanej styrenem i/lub zawierajacej gru¬ py metylolowe w pozycji (J pierscienia furanowe¬ go. Po okresie zywotnosci wystarczajacym do uformowania rdzeni, masa furanowa wedlug ni¬ niejszego wynalazku wykazuje gwaltowny wzrost wytrzymalosci mechanicznej. Nie ulega watpliwo¬ sci, iz jest to efektem duzej aktywnosci grupy aminowej Y~amin°Pr°Pyl°tróJetoksykrzemometanu w reakcjach z grupa karbonylowa ketonu cyklo¬ alifatycznego i grupami metylolowymi w pozycji P pierscienia furanowego.Y-aminopropyltriethoxysilomethane was introduced in an amount of 0.1-2.0% by weight in relation to resin to molding sand and core changes the course of the initial stage of hardening the resin modified with styrene and / or containing a methylol py at position (J furan ring him. After a period of life sufficient for formation of cores, furan mass according to them of the present invention shows a rapid growth mechanical strength. There is no doubt sci, that it is the result of high group activity amine Y ~ amino ° Pr ° Pyl ° trJetoxysilomethane in reactions with the carbonyl group of the cyclo ketone aliphatic and methylol groups in position P furan ring.
