Description
По предлагаемому способу лаки получают на основе поливинилацетальных смол эфиров оксижирных кислот с длинной цепью, а также циклических смол ных кислот, не растворимых в воде, или смол ных кислот циклического строени , имеющих двойные св зи, с добавкой пластификатор ов.In the proposed method, lacquers are obtained on the basis of polyvinyl acetal resins of long-chain oxy fatty acid esters, as well as cyclic resin acids that are not soluble in water, or cyclic resin acids with double bonds, with the addition of plasticizer.
Наибольшее значение из поливинилацетальных смол могут иметь смолы , получаемые конденсацией поливинилового спирта с уксусным альдегидом , масл ным или фурфуролом, или смесью их; в качестве эфиров оксикислот можно примен ть природные жиры, содержащие карбоксильную и гидроксильную группы, как например, касторовое масло, а также эфиры кислот, получаемые окислением, насыщенных углеводородов , циклических и ненасыщенных , содержащих оксигруппы. Смол ные кислоты можно вводить в виде канифоли, шеллака и других природных смол, содержащих свободные кислоты. Смол ные кислоты ускор ют процесс отверждени и в то же врем , в отличие от других минеральных и органических кислот, не разрушают ткани или бумагу.The highest value of polyvinyl acetal resins can have resins obtained by condensation of polyvinyl alcohol with acetaldehyde, oil or furfural, or a mixture of them; as hydroxy esters, natural fats containing carboxyl and hydroxyl groups, such as castor oil, as well as esters of acids obtained by oxidation, saturated hydrocarbons, cyclic and unsaturated, containing hydroxy groups can be used. Resin acids can be introduced in the form of rosin, shellac and other natural resins containing free acids. Resin acids accelerate the curing process and, at the same time, unlike other mineral and organic acids, do not destroy tissue or paper.
Введение эфиров оксикислот и смол ных кислот повышает эластичность пленки после термической обработки, а также адгезионную способность пленки к различным материалам, в особенности к ткани, бул1аге и древесине .The introduction of esters of hydroxy acids and resin acids increases the elasticity of the film after heat treatment, as well as the adhesion ability of the film to various materials, in particular, to fabric, bullet and wood.
Можно примен ть самые разнообразные пластификаторы в зависимости от назначени модифицированной смолы.A wide variety of plasticizers can be used depending on the purpose of the modified resin.
Пример:Example:
Поливинилбутирал - 50 в. ч.Polyvinyl butyral - 50 in. h
Резольной феноформальдегидной смолы - Ю в. ч.Phenolic phenol-formaldehyde resin - Yu. h
Касторового масла - 15 в. ч.Castor oil - 15 in. h
Канифоли или шеллака - 10 в. ч.Rosin or shellac - 10 c. h
Трикрезилфосфата - 15 в. ч.Tricresyl phosphate - 15 in. h
Все компоненты совмещаютс в спиртовом растворе при нагревании до температуры 6Q-70° С и тщательном перемешивании. Количество компонентов, образующих смол ной комплекс, и растворител может колебатьс в широких пределах.All components are combined in an alcohol solution when heated to a temperature of 6Q-70 ° C and thoroughly mixed. The number of components forming the resin complex and the solvent can vary widely.
Практическое применение могут найти лаки, содержащие от 90 до 50% растворител (этилового спирта, ацетона или смесей указанных рас185Lacquers containing from 90 to 50% of a solvent (ethyl alcohol, acetone, or mixtures of these types can find practical application.
