Description
Широко известны способы получени эпоксидных смол, модифицированных другими смолами, например, фенольными, мочевинными.Methods for the preparation of epoxy resins modified with other resins, e.g., phenolic, urea, are widely known.
Предлагаемый способ получени модифицированных эпоксидных смол путем добавлени к эпоксидной смоле продуктов конденсации диметилрезорцина с формальдегидом позвол ет получать смолы, обладающие лучшими адгезионными свойствами и повышенной теплостойкостью. Получаемые по описываемому способу смолы рекомендуютс в качестве св зующих дл производства стеклопластиков. При растворении совмещенной эпоксидной смолы в ацетоне получают лак и па основе его пропитанную ткань.The proposed method for producing modified epoxy resins by adding to the epoxy resin condensation products of dimethyl resorcin with formaldehyde allows to obtain resins with better adhesion and high heat resistance. The resins produced by the method described are recommended as binders for the production of glass-reinforced plastics. When a combined epoxy resin is dissolved in acetone, a lacquer is obtained and its impregnated fabric is pas based.
