Description
Изобретение относитс к изготов лёнию изделий из эпоксидных смол и может найти применение в машиностроении при изготовлении технологической оснастки из пластических масс, например , литейных моделей, штампов в производстве товаров народного потреблени .The invention relates to the manufacture of articles of epoxy resins and can be used in mechanical engineering in the manufacture of tooling from plastics, for example, casting models, dies in the production of consumer goods.
Известен способ изготовлени маркированных изделий из эпоксид«ых смол, в котором операци маркировани осуществл етс запрессовкой бумаг с нанесенным изображением и приклеиванием табличек с нанесенным изображением U. :A known method of making labeled products of epoxy resins, in which the marking operation is carried out by pressing in papers with the printed image and gluing the plates with the printed image U.
Однако этот способ не позвол ет получать маркированные издели с особой художественной выразительностью. Кроме того, требуетс дополнительное изготовление таблиц и их крепление.However, this method does not allow to obtain labeled products with particular artistic expressiveness. In addition, additional manufacturing of tables and their fastening is required.
Известен также способ изготовлени маркированных изделий из эпоксидных смол, включающий формообразование изделий, путем заливки смолы в форму, отверждение термообработкой и маркировку изделий. Необходимые надписи при известном способе нанос тс нитрокраской вручную либо методом .запрессовки бумаг с нанесенными надпис ми 2 3.There is also known a method of making labeled products from epoxy resins, which includes forming the products by pouring the resin into a mold, curing by heat treatment and labeling of the products. Necessary inscriptions with a known method are applied by nitro painting either manually or by pressing a paper with inscriptions 2 3.
Недостатком известного способа вл етс то, что в случае применени нитрокраски способ маркировани не позвол ет получать прочное изображение: краска быстро слущиваетс с поверхности полностью отвержденного эпоксипласта.The disadvantage of the known method is that in the case of applying nitro-painting, the marking method does not allow to obtain a strong image: the paint is quickly exfoliated from the surface of the fully cured epoxy plastic.
Кроме того, применение метода запрессовки - сложный и трудоемкий In addition, the application of the pressing method is complex and time consuming.
10 процесс, требующий особой бумаги и краски, не размокающих в эпоксидной композиции..10 process requiring special paper and paint not soaking in epoxy composition.
Целью .изобретени вл етс повышение эффективности процесса.The purpose of the invention is to increase the efficiency of the process.

Поставленна цель достигаетс тем, что согласно способу изготовлени маркированных изделий из эпоксидных смол, включающему, формообразование изделий путем заливки смолы в форму, This goal is achieved in that according to the method of making labeled articles made of epoxy resins, including forming the products by pouring the resin into a mold,
20 отверадение термообработкой и маркировку изделий, термообработку осуществл ют в две стадии, первую из которых провод т до глубины отверждени 85-90%, а маркировку изделий 20 absorption by heat treatment and labeling of products, heat treatment is carried out in two stages, the first of which is carried out to a depth of curing of 85-90%, and labeling of products
25 производ т гор чим тиснением после первой стадии термообработки.25 is produced by hot stamping after the first heat treatment step.
Оптимальной глубиной отверждени вл етс 85-90%. Ниже85% эпоксйплас имеет низкую упругость, выше 90% 30 высокую, котора не способствует .,The optimum cure depth is 85-90%. Below 85% epoxyplast has a low elasticity, above 90% 30 high, which does not contribute.,
