Description
Изобретение относитс к способам получени полифункциональных алифатическициклоалифатических эпоксидных смол. Известен опособ получени алифатическициклоалифатических эпоксидных смол на основе непредельных адеталей, например 1:1бис- (оксиметил)-циклогексена-3, путем эпоксидировани его сначала эпихлоргидрином в присутствии едкого иатра, а затем надкислотами по месту двойных св зей. Теплостойкость этих смол невелика: 30- 80° по Мартеису. Целью изобретени вл етс повышение теплостойкости в сочетании с высокой элас- 15 ТИЧНОСТЬЮ. Согласно изобретению в качестве исходного ацетал предложено использовать соединение формулы . O-CHt- -OHjOH всчс с; где R - лю1бые циклические радикалы, содержащие 1ПО крайней мере одну двойную св зь, способную при действии надкислот или других эпоксидирующих агентов образовывать окиси, например 10 20 25 30 Способ получени алифатическициклоалифатических эпоксидных смол, согласно изобретению , включает в себ обработку циклического непредельного моноацетал пентаэритрита , полученного конденсацией «впредельного циклического альдегида с пентаэритрИтом эпихлоргидрином в присутствии щелочи с получением диглицидиловых эфиров и последующего Э1поксидирова1ни их растворами надкислот по месту двойной св зи. Дл получени моноацетал может быть использован тетраг .идробензальдегид, метилтетрагидробензальдегид , эндометилентетратидробензальдегиды и т. п. Полученные смолы, в отличие от известных смол того же типа, имеют теплостойкость по Мартенсу до 125°. Эпоксидные смолы, полученные по предлагае .мому способу, отверждаютс известными отвердител ми ангидридного и аминного тилов и могут Найти практическое применение дл получени пропиточных компаундов электротехнического назначени и св зующих дл стеклопластиков.This invention relates to methods for producing polyfunctional aliphatic cycloaliphatic epoxy resins. A known method for the preparation of aliphatic-cycloaliphatic epoxy resins based on unsaturated adatals, for example, 1: 1 bis- (oxymethyl) cyclohexene-3, by epoxidizing it first with epichlorohydrin in the presence of caustic acid and then peracids at the place of double bonds. The heat resistance of these resins is small: 30-80 ° according to Marteis. The aim of the invention is to increase the heat resistance in combination with high elastia. According to the invention, it is proposed to use a compound of the formula as a starting acetal. O-CHt- -OHjOH vs c; where R is any cyclic radicals containing 1O at least one double bond capable of forming oxides under the action of peracids or other epoxidizing agents, for example 10 20 25 30 A method for producing aliphatic cycloaliphatic epoxy resins according to the invention, includes processing of cyclic unsaturated mono acetal pentaerythritol, obtained by condensation of the prelimit cyclic aldehyde with pentaerythritol epichlorohydrin in the presence of alkali to obtain diglycidyl ethers and subsequent E1poxy They are peracid solutions at the double bond site. For the preparation of monoacetal, tetragene. Hydrobenzaldehyde, methyltetrahydrobenzaldehyde, endomethylene tetrahydrobenzaldehyde, etc. can be used. The obtained resins, in contrast to the known resins of the same type, have Martens heat resistance up to 125 °. The epoxy resins obtained according to the proposed method are cured with known hardeners of anhydride and amine types and can find practical application for the preparation of impregnating compounds for electrical purposes and binders for glass-reinforced plastics.
