Description
(54) Sposob farbenia lisovacích kompozici! na báze nenasýtených polyesterových živíc(54) Dyeing method for molding compositions! based on unsaturated polyester resins
Vynález popisuje farbenie lisovacích kompozici! za použitia anorganických pigmentov. Podstata riešenia spočívá v tom, že pigment sa před vnesením do kompozície disperguje v tenzidoch na suspenziu vo formě, ktorej sa homogenizuje so zložkami polyesterovej kompozície.The invention discloses dyeing molding compositions. using inorganic pigments. The principle of the solution is that before the pigment is introduced into the composition, it is dispersed in surfactants into a suspension in a form which is homogenized with the components of the polyester composition.
Vynález sa týká spůsobu farbenia lisovacích kompozici! ,na báze inenasyiených polyesterových živíc anorganickými pigmentami.The invention relates to a method for dyeing molding compositions. , based on inasinated polyester resins with inorganic pigments.
Lisovacie kompozície na báze nenasytených polyesterových živíc sú známe (Čs. aut. osv. č. .226 283). Priemyselne sa pripravujú najčastejšie zahuštěním polyesterovej kompozície za použitia oxidu horečnatého. Poměrně šiřoká aplikačná škála různých výrobkov na ich báze je sprevádzaná aj použitím roznych pigmentov na ich vyfarbenie. Tieto sa zvyčajne dávkujú bud ako suspenzie v esteroch, alebo polyesteroch. Z důvodu polárného charakteru anorganických pigmentov v nepolárnom roztoku nenasýtenej polyesterovej živice, sú často spojené problémy s nerovnoměrným vyfarbením povrchu lisovaných výrobkov. Prídavok různých tenzidov priamo do zmesi sa ukázal ako málo účinný, hlavně z důvodu, že anorganické pigmenty v esteroch alebo polyesteroch sú obalené vrstvou, ktorá zamedzuje styku s povrchovoaktívnou látkou. Pri aplikačnom výskume bolo zistené, že tieto problémy sa podstatné odstránia pri použití riešenia podlá vynálezu.Pressurized compositions based on unsaturated polyester resins are known (U.S. Pat. No. 226 283). They are industrially prepared most often by concentrating the polyester composition using magnesium oxide. A relatively wide application range of various products based on them is also accompanied by the use of various pigments to color them. These are usually dosed either as suspensions in esters or polyesters. Due to the polar nature of the inorganic pigments in the non-polar solution of the unsaturated polyester resin, problems with uneven coloration of the surface of the molded articles are often associated. The addition of various surfactants directly to the composition has proven to be ineffective, mainly because the inorganic pigments in the esters or polyesters are coated with a coating that prevents contact with the surfactant. It has been found in the application research that these problems are substantially eliminated using the solution according to the invention.
Vynález popisuje sposob farbenia lisovacích kompozici! na báze nenasytených polyesterových živíc anorganickými pigmentami. Podstatou vynálezu je, že práškový anorganický pigment sa před vnesením do polyesterovej kompozície disperguje v povrchovoaktívnych látkách o viskozite nižšej ako 15 000 mPas/20 °C, na suspenziu obsahujúcu 5 až 85 % hmot. pigmentu a v tejto formě sa homogenizuje so zložkami polyesterovej kompozície.The invention describes a method for dyeing molding compositions. based on unsaturated polyester resins with inorganic pigments. It is an object of the invention that the powdered inorganic pigment is dispersed in surfactants with a viscosity of less than 15,000 mPas / 20 ° C, before being introduced into the polyester composition, to a suspension containing 5 to 85 wt. pigment and in this form is homogenized with the components of the polyester composition.
Vyšší účinok podlla vynálezu spočívá v tom, že povrchovoaktívne látky sú zlúčeniny amfipatického charakteru v důsledku čoho nastáva ich orientácia na povrchu pigmentu, ktorý sa týmto spůsobom stává nepolárný, t. j. dobré zlúčiteíný s nepolárným roztokom nenasýtenej polyesterovej živice. Odborníkom je zřejmé, že k tomuto účelu je možné použit celý rad tenzidov. Z důvodu aby bolo možné připravit’ suspenziu s dobrými tokovými vlastnosťami, je však potřebné pri ich výbere použit kvapalné zlúčeniny a ich zmesi o viskozitě nižšej ako 15 000 mPas/20 °C. V případe potřeby je však možné konzistenciu suspenzie upravovat’ napr. •styrénam, plastifikátorom a pod.A higher effect according to the invention is that the surfactants are amphipathic compounds, as a result of which they are oriented on the surface of the pigment, which in this way becomes non-polar, i. j. well compatible with a non-polar solution of unsaturated polyester resin. Those skilled in the art will recognize that a variety of surfactants can be used for this purpose. However, in order to prepare a suspension having good flow properties, it is necessary to select liquid compounds and mixtures thereof with a viscosity of less than 15,000 mPas / 20 ° C. However, if desired, the consistency of the suspension can be adjusted " e.g. • styrene, plasticizer and the like.
Vynález je ďalej objasněný formou príkladov, v ktorých zloženie je uvádzané v hmot. koncoutrácii.The invention is further elucidated by way of examples in which the composition is given in wt. koncoutrácii.
