Hoci sa môže vynález využiť pre široký rozsah výrobkov, je výhodný najmä pri výrobe dielov pre motocykle a vozidlá, a preto bude z tohto dôvodu popísaný v súvislosti s nimi s odkazom, že vynález má širšie využitie.The invention relates to a method for producing a colored solid object and to the object itself. Although the invention can be used for a wide range of products, it is particularly advantageous in the manufacture of parts for motorcycles and vehicles and will therefore be described in connection with them with reference that the invention has wider application.
Doterajší stav technikyBACKGROUND OF THE INVENTION
Niektoré vozidlá, hlavne ťažké priemyselne využiteľné vozidlá ako sú bágre, sú náchylné na poškodenie. I keď môžu vozidlá mať kovové diely ako vonkajšie kryty, je oveľa ekonomickejšie, ak sú diely zhotovené z lacnejšieho pevnejšieho materiálu. Plasty sú bežnými vhodnými materiálmi, ale nemajú atraktívnu farbu. Spis EP-A-0 266 107 popisuje výrobok použiteľný ako diel automobilu a obsahujúci povlak z polymerizačnej fólie zhotovenej z pigmentovanej akrylovej vrstvy pripojenej adhezívne k vrstve PVC a nesenej polymerizačnou vrstvou. Diel je zhotovený vstrekovaním polyméru na vrstvu umiestnenú vo forme s vrstvou PVC umiestnenou najviac vo vnútri. Toto je potrebné vykonať pri spôsobe výroby tuhého voči nárazu odolného dielu, ktorý má atraktívne jasné farby.Some vehicles, especially heavy industrial vehicles such as excavators, are susceptible to damage. Although vehicles may have metal parts as outer covers, it is much more economical if the parts are made of cheaper, stronger material. Plastics are common suitable materials but are not attractive in color. EP-A-0 266 107 discloses an article for use as an automobile part and comprising a polymeric film coating made of a pigmented acrylic layer bonded adhesively to a PVC layer and supported by a polymerization layer. The part is made by injecting the polymer onto the layer placed in the mold with the PVC layer placed most inside. This is to be done in a method for producing a impact-resistant part having attractive bright colors.

Príklady uskutočnenia vynálezuDETAILED DESCRIPTION OF THE INVENTION
Výlisok 1 obsahujúci jednu vrstvu 1A z akrylonitrilbutadiénstyrénu a druhú vrstvu 1B z pigmentovaného tuhého modifikovaného polymetakrylátu je tepelne alebo vákuovo tvarovaný vo vhodnej neznázornenej vákuovej forme pri teplote okolo 160 až 170 °C do požadovaného profilu P plášťa požadovaného výrobku. Výlisok je vybraný podľa vlastností vyžadovaných pri konečnom použití; vo výhodnom vyhotovení má výlisok mernú hmotnosť okolo 1,1 gm/cm3 a hrúbku okolo 2 mm; pevnosť v ťahu je od okolo 30 do približne 40 MPa a medza pevnosti v ohybe je od okolo 50 do približne 55 MPa a ohybový modul je okolo 2,2 Gpa. Bežný výlisok má teplotu mäknutia podľa Vicata od okolo 97 do približne 101 °C.Molding 1 comprising one layer of acrylonitrile butadiene styrene 1A and the other layer 1B of pigmented solid modified polymethacrylate is thermally or vacuum molded in a suitable vacuum form (not shown) at a temperature of about 160-170 ° C to the desired shell profile P of the desired product. The compact is selected according to the properties required in the end use; in a preferred embodiment, the compact has a density of about 1.1 gm / cm 3 and a thickness of about 2 mm; the tensile strength is from about 30 to about 40 MPa and the flexural strength is from about 50 to about 55 MPa and the flexural modulus is about 2.2 Gpa. A conventional compact has a Vicat softening temperature of from about 97 to about 101 ° C.
Tuhý penový nosný podklad B je nanesený na profil P vo forme znázornenej na obr. 1. Forma obsahuje základ 2 a horný diel 3; a má bočné steny 4. Bočné steny 4 sú tvorené spodnou polovicou 4A a hornou polovicou 4B prispôsobenými na nesenie voľných koncov profilu P. Základná hmota samo tvrdnúceho plniva 5, napríklad plneného plastu, je umiestnená v spodnej polovici skrine formy do podoby požadovaného tvaru M. Spodná polovica H1 škrupiny je umiestnená na tuhnúcej základnej hmote. Spodná polovica H1 škrupiny má tvarovanú hornú stenu, na ktorú je umiestnený profil P s druhou vrstvou 1B smerujúcou dole a trubice 6 na priechod ohriateho média. Polovica škrupiny je zhotovená zo skleneného epoxidového laminátu alebo materiálu s podobnou presnosťou tak, že profil má presné rozmery a nebude sa pohybovať počas lisovania. Neznázornená výstuž z materiálu VETROTEX je umiestnená a potom je netvrdená polyuretánová zmes 7 dodaná na hornú, t.j. zadnú prvú vrstvu 1A profilu P. Vložka 8 je umiestnená k jednému koncu. Horná polovica H2 škrupiny je umiestnená nahor po doplnení plniva 5 a potom je priložený horný diel 3. Tento celok je vložený do neznázorneného hydraulického lisu. Horúca voda prechádza trubicami 6 kvôli dodaniu tepla spôsobujúceho vypenenie a vytvrdenie polyuretánovej zmesi. Toto prebieha okolo dvoch minút. Voda je vypustená a tvar M je vybraný z lisu a rozobratý. Profil P s tuhou penovou výplňou s vysokou mernou hmotnosťou je vybraný a upravený do požadovaného tvaru aThe rigid foam backing B is applied to the profile P in the form shown in FIG. The mold comprises a base 2 and an upper part 3; The side walls 4 are formed by a lower half 4A and an upper half 4B adapted to support the free ends of the P-profile. The matrix of the self-curing filler 5, for example filled plastic, is placed in the lower half of the mold housing in the desired shape M. The lower shell half H1 is located on the solidifying matrix. The lower shell half H1 has a shaped upper wall on which a profile P with a second layer 1B facing downwards and a tube 6 for passing the heated medium is placed. Half of the shell is made of glass epoxy laminate or a material with similar accuracy so that the profile has exact dimensions and will not move during the pressing. A VETROTEX reinforcement (not shown) is placed and then the uncured polyurethane mixture 7 is delivered to the top, i.e. a back first layer P profile 1A. The insert 8 is disposed at one end. The upper half of the H2 shell is placed upward after the filler 5 has been added and then the upper part 3 is attached. This assembly is inserted into a hydraulic press (not shown). The hot water passes through the tubes 6 to provide heat to cause foaming and curing of the polyurethane composition. This takes about two minutes. The water is drained and the M shape is selected from the press and disassembled. The high density P foam profile P is selected and shaped to the desired shape a
