Description
Дл изготовлени упругих моделей в лаборатори х, производ щих исследовани напр жений пол ризационно-оптическим методом, примен ют фенолформальдегидные, глифталевые и стиролалкидные смолы. Однако эти материалы не обладают всем комплексом необходимых свойств и размеры изготовл емых на их основе моделей недостаточно велики . Кроме того, указанные материалы в форме, пригодной дл выполнени упругих моделей, изготовл ютс по сложной технологии и только в некоторых лаборатори х оптического метода, преимушественно дл собственных нужд этих лабораторий .Phenol-formaldehyde, glyphthalic and styrene alkyl resins are used to make elastic models in laboratories performing stress studies using the polarization-optical method. However, these materials do not have all the necessary properties and the sizes of models manufactured on their basis are not large enough. In addition, these materials in a form suitable for making elastic models are made using sophisticated technology and only in some laboratories of the optical method, mostly for the in-house needs of these laboratories.
Литьева композици на основе эпоксидной смолы и малеинового ангидрида может с успехом примен тьс при изготовлении прозрачных моделей, пригодных дл пол ризационно-оптического метода исследовани напр жений в детал х машин и элементах конструкций. Предлагаема эпоксидна смола отвердевает без усадки и без выделени летучих веществ, что вл етс ее большим преимуществом по сравнению сThe molding composition based on epoxy resin and maleic anhydride can be successfully used in the manufacture of transparent models suitable for the polarization-optical method for studying stresses in machine parts and structural elements. The proposed epoxy resin hardens without shrinkage and without the release of volatile substances, which is its great advantage compared to
другими материалами, примен емыми дл изготовлени оптических упругих моделей.other materials used to make optical elastic models.
Литьевую композицию дл изготовлени прозрачных моделей приготовл ют путем быстрого и тщательного смешени в фарфоровой чашке 100 вес. ч. нагретой до 70- 80 эпоксидной смолы с 30 вес. ч. расплавленного малеинового ангидрида . Перемешивание производ т 6-7 мин., после чего композицию заливают в подогретые до 60-70° формы. Формы предварительно обрабатывают дл предотвращени прилипани эпоксидной смолы к металлу . После заливки форму со смолой выдерживают 20-30 мин. при комнатной температуре и помещают в обогреваемый шкаф при температуре 60°.The casting composition for the manufacture of transparent models is prepared by quickly and thoroughly mixing in a porcelain dish 100 weight. including heated to 70-80 epoxy resin with 30 wt. including molten maleic anhydride. Mixing is carried out for 6-7 minutes, after which the composition is poured into forms heated to 60-70 °. The molds are pretreated to prevent the epoxy resin from sticking to the metal. After pouring, the resin mold is held for 20-30 minutes. at room temperature and placed in a heated cabinet at a temperature of 60 °.
Режим отверждени зависит от толщины отливки. Например, при толщине отливки менее 15-20 мм ее нагревают при 70 затем в течение 6 час. поднимают температуру с 70 до 120° и при этой температуре выдерживают 20-24 часа, после чего в течение 6 час. температуру снижают до комнатной. При большей толNO 114780 - 2-The curing mode depends on the thickness of the casting. For example, if the casting thickness is less than 15-20 mm, it is heated at 70 then for 6 hours. the temperature is raised from 70 to 120 ° and kept at this temperature for 20-24 hours, after which for 6 hours. the temperature is reduced to room temperature.
