Description

Р1звестен способ ползчени  лакорых смол на основе глифтален, модифицированных растительными маслами и эпоксидными соединени ми.There is a known creeping method for lacquer resins based on glyphthalene modified with vegetable oils and epoxy compounds.

Описываемый способ по сравнению с известным повышает твердость и теплостойкость лаковых смол на основе глифталей.The described method in comparison with the known increases the hardness and heat resistance of varnish resins based on glyptale.

С этой целью в качестве эпоксидного соединени  используют арилдиглицидные эфиры.For this purpose, aryl diglycid esters are used as the epoxy compound.

Способ осуществл ют следующим образом. Прн 200-260° переэтерифицируют известным нутем растительные масла (льн ное, тунговое, хлопковое и другие) глицерином. По окончании реакции переэтерификации в полученную смесь моно-и диглицеридов жирных кислот растительных масел при 200-260° загружают арилдиглицидный (или алкилдиглицидный ) эфир и в течение 2-5 час. ведут процесс при этой температзфе до полного вступлени  в реакцию эпоксидных грунн эфира. Затем загружают фталевый ангидрид и при той же температуре ведут процесс до получени  смолы с необходимым кислотным числом.The method is carried out as follows. The 200-260 ° C is transesterified with the known chickpeas vegetable oils (flax, tung, cotton and others) glycerol. At the end of the transesterification reaction, aryl diglycidic (or alkyl diglycidic) ether is added to the mixture of mono- and diglycerides of fatty acids of vegetable oils at 200-260 ° and for 2-5 hours. The process is carried out at this temperature until the epoxy primer of ether is fully reacted. Phthalic anhydride is then charged and the process is carried out at the same temperature until a resin with the required acid number is obtained.

Дл  получени  лаковой смолы на основе глифталей примен ют, например, следующую рецептуру в %% (из расчета на жирный тип): масла льн ного-50,3, глицерина-17,7, фталевого ангидрида-25,5, диглицидного эфира диоксидифенилпропана-6.5. Конечное кислотное числе смолы 5,8.For the preparation of a glyptal-based lacquer resin, for example, the following formulation is used in %% (based on the fat type): linseed oil-50.3, glycerin-17.7, phthalic anhydride-25.5, diglycid ether dioxydiphenylpropane- 6.5. The final acid number of the resin is 5.8.

Таким же путем могут быть получены средние и тощие типы смол при различном соответствии фталевого ангидрида и диглицидного эфира.In the same way, medium and lean types of resins can be obtained with different correspondence of phthalic anhydride and diglycid ether.

Полученные смолы раствор ютс  в ароматических растворител х, кетонах и различных смес х растворителей.The resulting resins are dissolved in aromatic solvents, ketones and various solvent mixtures.

Предмет изобретени Subject invention

Способ, получени  лаковых смол на основе глифталей, модифицированных растительными маслами и эпоксидными соединени ми, отличающийс  тем, что, с целью повышени  твердости и теплостойкости смол, в качестве эпоксидного соеди«ени  используют арилдиглицидные эфиры.The method of obtaining lacquer resins based on glyptal, modified with vegetable oils and epoxy compounds, characterized in that, to increase the hardness and heat resistance of the resins, aryl diglycide esters are used as epoxy compounds.
