Description

Najdluzszy czas trwania patentu do 12 czerwca 1944 r.W patencie Nr 10636 opisano sposób o- trzyanywania przedmiotów ze sztucznych mas, iznamieminy tern,, ze produkty konden¬ sacji, otrzymane z amin aromatycznych i aldehydów w obecnosci kwasu, tirakt/uje sie srodkami, zdolnemu do usuniecia kwasu, pozostalego w tych produktach, i tak o- trzymane nietopliwe produkty po wysusze¬ niu silacza sie w postaci rozdrobnionej.Okazalo sie, ze przy wytwarzaniu przedimiotów o skomplikowanej formie dla ulatwienia ksztaltowania daje dobre wyni¬ ki obecnosc srodka uplynniajacego (topni¬ ka) w tloczonym proszku.Obecmie wykryto, ze jakp takie topniki nadaja sie topliwe produkty kondensacji aldehydów, jak miedzy innemi topliwe produkty kondensaqji amido-aldehydowe np. anhydrofonmaldehydioaniilina albo to¬ pliwe zywice, opisane w patentach Nr 12934 i Nr 12935, dodatkowych do patentu Nr 10636, nastepnie topliwe produkty kon¬ densacji aldehydu z fenolami i t. d.Topniki mozna dodawac do proszków, albo w postaci gotowej, albo tez mozn,a je wytwarzac podczas stlaczania ze skladni¬ ków.Otrzymane mieszaniny iz proszków, wy¬ tworzonych sposobem wedlug patentu Nr 10636, z topnikami dzieki swej doskonalejwlasnosci jroEplywania sie umozliwiaja do¬ skonale, formowanie przy znacznie niz¬ szych temperaturach i w znacznie (krót¬ szym czasie, niz to bylo konieczne prizy u- zyciu samych proszków, otrzymywanych wedlug patentu Nr 10636.Obnizenie temperatury stlaczania oraz skrócenie cteasu stlaczania zalezy od* uzy¬ tej ilosci, oraz od rodzaju topnika.Przyklad L 100 czesci proszku, otrzy¬ manego wedlug patentu Nir 10636 z jedne¬ go mola aniliny i 1,6 mola aldeliydu mrów¬ kowego, wymagajacego temperatury stla- clzania okolo 230°C, miesza sie ze 100 cze¬ sciami anhydroformaldehycjoaniliny. Mie¬ szanina daje sie przy 150°C stlaczac na ztipelnie jednorodne nietopliwe przedmio- ty.Przyklad II. 100 czesci prosteku, da¬ jacego sie ksztaltowac w temperaturize o- kolo 150°C, otrzymanego wedlug patentu, Nin 10636 z jednego mola aniliny i 1,2 mo¬ la aldehydu mrówkowego, miesza sie z 8 czesciami topliweij zywicy, ottfzymanej we¬ dlug patentu Nr 12934 z jedinego mola aniliny i jednego mola aldehydu mrówko¬ wego. Mieszanina daje sie stlaczac przy 120—130°C na jednorodne nietopliwe przedmioty.Przyklad III. 100 czesci proszku, o- tDzymanego wedlug patentu Nr 10636 z jednego mola aniliny i 1,6 mola aldehydu mrówkowego, wymagajacego temperatury stlaczania okolo 230°C, miesza sie z 5 cze¬ sciami fenolu. Mieszanina daje sie stlaczac najednorodne nietopliwe przedmioty w 150°C. Zastapienie fenolu anilina w tym przykladzie daje podobne dobre wyniki.Niewielkie ilosci topnika mozna zmie¬ szac z prosizkiem na jednorodna mase, roz¬ puszczajac najprzód topnik w jakims roz^ puszczalniku np. w alkoholu, acetonie, beczenie i t, d. i nastepnie przesycajac proszek tym roztworem, poczem rozpu¬ szczalnik usuwa sie, w razie potrzeby w prózni. PLThe longest term of the patent until June 12, 1944 The patent No. 10636 describes a method of applying artificial masses, isnamimines, and the condensation products obtained from aromatic amines and aldehydes in the presence of acid, thiract is used with agents capable of After the removal of the acid remaining in these products, and the thus obtained infusible products, after drying, are ground into a comminuted form. It has been found that in the production of objects of complicated form to facilitate shaping, the presence of a fluid (melting agent) gives good results. ) in the pressed powder. It has now been found that such fluxes are suitable for melting aldehyde condensation products, such as, among others, amide-aldehyde fusible condensation products, e.g. 10636, then the fusible condensation products of the aldehyde with phenols, etc. The torches can be added to powders and ready-made, or it can be produced during mixing from the ingredients. The obtained mixtures of powders, prepared according to the patent No. 10636, with fluxes, thanks to their excellent heat properties, allow for perfect molding at much lower temperatures. and in a much (shorter time than was necessary due to the use of the powders themselves, obtained according to patent No. 10636). The reduction of the pour point and the reduction of the setting time depends on the amount used and the type of flux. Example L 100 parts of powder of one mole of aniline and 1.6 moles of form aldeliide, which requires a setting temperature of about 230 ° C., is mixed with 100 parts of anhydroformaldehydeaniline. The mixture can be poured at 150 ° C. into a perfectly homogeneous infusible object. Example II. 100 parts of a rectangle, formable at a temperature of about 150 ° C, obtained according to the patent, Nin 10636 from one mole of aniline and 1.2 mole of formaldehyde, mixed with 8 parts of meltable resin, framed with a length of string. of Patent No. 12934 of one mole of aniline and one mole of formaldehyde. The mixture can be aggregated at 120-130 ° C into homogeneous non-fusible objects. 100 parts of a powder, obtained according to Patent No. 10636, from one mole of aniline and 1.6 moles of formaldehyde, requiring a settling temperature of about 230 ° C, are mixed with 5 parts of phenol. The mixture is able to form homogeneous infusible objects at 150 ° C. The replacement of the phenol with aniline in this example gives similar good results. Small amounts of the flux can be made into a homogeneous mass with the powder by first dissolving the flux in some solvent, e.g. alcohol, acetone, bleeding, etc., and then saturating the powder. with this solution, the solvent is then removed, if necessary under a vacuum.
