Description
При производстве алкидных смол, дл чего обычно берут смесь фталевого ангидрида, глицерина и касторового или высыхающего масла, совершаетс сложный процесс образовани высокомолекул рных эфиров и одновременно, если берут касторовое масло, протекает его дегидратаци с образованием глицеридов октадекадиен-9, 11-кислоты 1.In the production of alkyd resins, for which a mixture of phthalic anhydride, glycerin and castor or drying oil is usually taken, the complex formation of high molecular weight esters takes place and at the same time, if castor oil is taken, it is dehydrated to form octadecadien-9, 11-acid glycerides 1.
В результате поликонденсации образуетс смесь полимергомологов различного строени , имеющих конечные гидроксильные или карбоксильные группы, а также разветвлени в отдельных част х молекул в виде углеводородных цепей жирных кислот.As a result of polycondensation, a mixture of polymer homologues of various structures with end hydroxyl or carboxyl groups is formed, as well as branching in separate parts of the molecules in the form of hydrocarbon chains of fatty acids.
Известно, что продолжительное нагревание при повышенной темпе.ратуре приводит к превращению алкидных смол в нерастворимое состо ние , вл ющеес результатом последующих процессов ноликонденсации или полимеризации за счёт углеводородных ценей ненасыш;енных жирных кислот.It is known that prolonged heating at an elevated temperature leads to the conversion of alkyd resins to an insoluble state, which is the result of subsequent processes of niocondensation or polymerization due to the hydrocarbon prices of unsaturated fatty acids.
При получении алкидных смол процесс ведут таким образом, чтобы готовый продукт имел наибольший средний молекул рный вес.In the preparation of alkyd resins, the process is carried out in such a way that the finished product has the highest average molecular weight.
Такие продукты особенно пригодны дл смешивани с нитроклетчаткой и другими эфирами целлюлозы , каучуком и высыхающими маслами.Such products are particularly suitable for blending with nitrocellulose and other cellulose ethers, rubber and drying oils.
Облада свойствами плёнкообразующих веществ, алкидные смолы сообщают покрыти м высокую Зстойчивость против атмосферных воздействий.Possessing the properties of film-forming substances, alkyd resins provide coatings with high resistance to weathering.
Получение же высокополимерных алкидных смол представл ет известные затруднени технологического характера.The production of high polymer alkyd resins is a known technological difficulty.
Стремление повысить средний молекул рный вес алкидных смол приводит к значительному повышению в зкости их растворов и сопр жено с опасностью возможного свёртывани смол.The desire to increase the average molecular weight of alkyd resins leads to a significant increase in the viscosity of their solutions and is associated with the danger of possible coagulation of the resins.
Кроме того скорость процесса поликонденсации резко снижаетс по .мере увеличени молекул рного веса смолы и возникает необходимость применени очень повышенной температуры дл достижени желательной степени конденсации.In addition, the rate of the polycondensation process decreases sharply as the molecular weight of the resin increases and it becomes necessary to use a very high temperature to achieve the desired degree of condensation.
Дл получени смол из многооснбвных кислот и многоатомных спиртов с применением высококип щих (растворителей авторами данного изобретени предлагаетс смесь многоосновных кислот и спиртов нагревать до 270° в присутствии жирных кислот или их глицеридов, после, чего добавл ть высококип щий растворитель и 1 - 2% диазоамидобензола, а затем выдерживать .массу при температуре не выше 150° до получени смолы определённой в зкости, растворимости и других СВОЙСТВ;To obtain resins from polybasic acids and polyhydric alcohols using high-boiling solvents, the authors of this invention propose to heat the mixture of polybasic acids and alcohols to 270 ° in the presence of fatty acids or their glycerides, after which add high boiling solvent and 1 to 2% diazoamido benzene and then maintain the mass at a temperature not higher than 150 ° until the resin has a certain viscosity, solubility and other PROPERTIES;
Предмет изобретени Subject invention
Способ получени смол из многоосновных кислот и многоатомных спиртов путём термической обработки их в присутствии жирных кислот или их глицеридов с применением высококип щих растворителей , о т л и ч а ю щ и и с тем, что после нагревани смеси жирных кислот и спиртов при температуре до 270° добавл ют высококип щий растворитель и 1-2% диазоамидобензола , после чего выдерживают массу при температуре ае выше 150°.The method of obtaining resins from polybasic acids and polyhydric alcohols by thermally treating them in the presence of fatty acids or their glycerides using high-boiling solvents, so that after heating the mixture of fatty acids and alcohols at 270 ° C add high-boiling solvent and 1-2% diazo-amidobenzene, and then maintain the mass at a temperature above 150 °.
