Description
примен емые эпоксидные смолы и издели на их основе обладают теплостойкостью до температуры 180°, что дл целого р да изделий вл етс недостаточным.The epoxy resins used and products based on them have a heat resistance up to 180 °, which is insufficient for a whole range of products.
В цел х повышени термостойкости смол, предложено совмещение эпоксидных смол с фурфурольно-ацетоновой смолой.In order to increase the heat resistance of resins, a combination of epoxy resins with furfural-acetone resin has been proposed.
Растворы эпоксидной и фурфурольно-ацетоновой смол смешивают в соотношении 70-10 частей первой и 30 - 90 второй. В полученный раствор добавл ют отвердитель , представл ющий собой смесь ароматической сульфокнслоты и веществ, обладающих способностью образовывать аддукты . Полученным раствором смолы пропитывают наполнитель (стеклоткань, асбест, графит и др.), а затем сушат и прессуют.Solutions of epoxy and furfural-acetone resins are mixed in a ratio of 70-10 parts of the first and 30 - 90 second. To the resulting solution is added a hardener, which is a mixture of aromatic sulfoxy acids and substances with the ability to form adducts. The resulting resin solution is impregnated with a filler (glass cloth, asbestos, graphite, etc.), and then dried and pressed.
Пример. Эпоксидную смолу ЭД-6 с температурой разм гчени 60° смешивают с фурфурольноацетоновой смолой резольного типа или с мономером этой смолы, например, метилвинил-р-фурилкетоном и добавл ют отвердитель (малеиновый ангидрид в количестве 10%1 к весу эпоксидной смолы и бензолсульфокислоту в количестве 2,о к весу фурфурольноацетоновой смолы). Полученной смолой пропитывают наполнитель и сушат.Example. ED-6 epoxy resin with a softening temperature of 60 ° is mixed with a resur-type furfuryl-acetone resin or with a monomer of this resin, for example methylvinyl-p-furyl ketone, and a hardener is added (maleic anhydride in an amount of 10% 1 by weight of epoxy resin and benzenesulfonic acid in an amount of 2, about the weight of furfurol-acetone resin). The resulting resin is impregnated with a filler and dried.
После сушки следует прессовка при удельном давлении 20- 40 KzjcM- и температуре 250-270.After drying, pressing follows at a specific pressure of 20-40 KzjcM- and a temperature of 250-270.
Предмет изобретени Subject invention
Способ получени совмеп;епных эпоксидных и других фепольноформальдегидных смол путем смешени , отличающийс тем, что, с целью увеличени теплостойкости смол, к эпоксидным или фенолько-формальдегидным смолам добавл ют от 10 до фур l yрольно-ацетоновых смол.The method of producing co-epoxy and other phepol-formaldehyde resins by mixing, characterized in that, in order to increase the heat resistance of the resins, epoxy or phenolic-formaldehyde resins are added from 10 to fur l or acetone resins.
