Description
(54} СПОСОБ ПОЛУЧЕНИЯ ОТВЕРЖДЕННЫХ ПОЛИЭФИРОВ(54} METHOD OF OBTAINING CIVIL POLYESTERS
Таблица 1Table 1
Оптимальным количеством дополнительного катализатора дл смолы ПН-1 вл етс I - 3% от веса полиэфирной смолы.The optimum amount of additional catalyst for the PN-1 resin is I — 3% by weight of the polyester resin.
Введение катализатора -в смолу ПН-1 сверх оптимального количества приводит к снижению физико-механических показателей.The introduction of the catalyst in the resin PN-1 in excess of the optimal amount leads to a decrease in physical and mechanical properties.
Пример 2. В 100 г смолы ПН-бЗ ввод т 4 г гипериза, смесь тщательно перемешивают, а затем добавл ют 10 г 10%-ного раствора нафтената кобальта в стироле и после перемешивани добавл ют требуемое количество 80%-кого раствора смолы МСН-7 в толуоле (см. табл. 2). В качестве дополнительного ускорител используют ванадиевый ускоритель (п тиокись ванади ).Example 2. In 100 g of a PN-BZ resin, 4 g of hyperise is introduced, the mixture is thoroughly mixed, and then 10 g of a 10% solution of cobalt naphthenate in styrene are added and, after mixing, the required amount of 80% solution of the MCH-resin is added 7 in toluene (see tab. 2). The vanadium accelerator (vanadium pentoxide) is used as an additional accelerator.
Приготовление композиций и их отверждение провод т при комнатной температуре. Свойства полученных отвержденных смол приведены в табл. 2.The compositions are prepared and cured at room temperature. The properties of the cured resins obtained are given in table. 2
Оптимальным количеством дополнительно катализатора дл смолы ПН-63 вл етс 2-3%.The optimal amount of additional catalyst for the PN-63 resin is 2-3%.
Введение дополнительного катализатора в смолу ПН-63 сверх оптимального количества приводит к снижению физико-механических показателей.The introduction of additional catalyst in the resin PN-63 in excess of the optimal amount leads to a decrease in physical and mechanical properties.
Пример 3. В 100 г. НПС-609-21М ввод тExample 3. 100 g. PS-609-21M is introduced
4 г гипериза, смесь тш:ательно перемешивают,4 g of hyperise, the mixture is mixed:
а затем добавл ют 10 г 10%-ного раствораand then add 10 g of a 10% solution
нафтената кобальта в стироле. После перемеТаблица 2cobalt naphthenate in styrene. After movingTable 2
шивани ввод т определенное количество 80%-кого раствора МСН-7 в толуоле (см. табл. 3).A certain amount of an 80% solution of MCH-7 in toluene is added (see Table 3).
Приготовление композиций и их отверждение провод т при комнатной температуре. Свойства отвержденных смол приведены в табл. 3. Оптимальным количеством дополнительного катализатора дл смолы НПС-609-21 М вл етс 0,4-0,6%.The compositions are prepared and cured at room temperature. The properties of the cured resins are given in table. 3. The optimal amount of additional catalyst for LPS-609-21 M resin is 0.4-0.6%.
Введение большего количества дополнительного катализатора не позвол ет получать эффект сокращени времени отверждени смолы.The introduction of a larger amount of additional catalyst does not allow the effect of reducing the cure time of the resin.
Таблица 3Table 3
Предмет изобретени Subject invention
Способ получени отвержденных полиэфиров путем сополимеризации ненасыщенных полиэфиров с мономерами в присутствии окислительно-восстановительной системы, отличающийс тем, что, с целью сокращени времени желатинизации и отверждени полиэфиров , в реакционную смесь дополнительно ввод т полиметилсилазановую смолу в количестве 0,4-3% от общего веса полиэфира и мономера.A method of producing hardened polyesters by copolymerizing unsaturated polyesters with monomers in the presence of a redox system, characterized in that, in order to shorten the time of gelatinization and curing of polyesters, polymethylsilazane resin is added to the reaction mixture in an amount of 0.4-3% by weight polyester and monomer.
