Изобретение касаетс сварки пластмасс.The invention relates to welding plastics.
Известен способ соединени термопластичных пленок, преимущественно полиэтилентерефталатовых , путем нагреВа и сдавливани с применением в качестве промежуточного материала органических перекисей.A known method of combining thermoplastic films, mainly polyethylene terephthalate, by heating and squeezing, using organic peroxides as an intermediate material.
Однако известный способ не обеспечивает получени сварного шва, идентичного по химическому составу основному материалу.However, the known method does not provide a weld that is identical in chemical composition to the base material.
Цель изобретени - повысить качество сварки.The purpose of the invention is to improve the quality of welding.
Дл этого в промежуточный материал введен флороглЮЦин. При этом указанные компоненты вз ты в следующем весовом соотно23 шении -- : --.For this purpose, florogluCin is introduced into the intermediate material. At the same time, these components are taken in the following weight ratio: -: -.
На месте соединени пленок нанос т равномерный слой промежуточного материала, .выдерживают в течение двух-трех минут на воздухе при комнатной температуре, пленки накладывают внахлестку друг на друга и помещают между электродами высокоч:астотной сварочной установкиAt the junction of the films, a uniform layer of intermediate material is applied, held for two to three minutes in air at room temperature, the films are superimposed overlapped and placed between the electrodes of a high-precision welding setup.

По предлагаемому способу соединены образцы пленки полиэтилентерефталата толщиной 0,1 мм. В качестве промел уточного сло используют 20%-ный ацетоновый раствор смеси лерекиси бензоила и флороглюцина с соотнощением компонентов 2:1 в количестве 0,4 мг на 1 см- поверхности щва из расчета на сухой остаток. Процесс протекает при 150-155°С, продолжительности нагрева в течение 10-15 сек и давлений 15-20 кгс/см.The proposed method is connected to samples of polyethylene terephthalate film with a thickness of 0.1 mm. A 20% acetone solution of a mixture of benzoyl lerekis and phloroglucin with a ratio of components of 2: 1 in an amount of 0.4 mg per 1 cm of schv surface based on dry residue was used as a weathered layer. The process takes place at 150-155 ° C, the duration of heating for 10-15 seconds and pressures of 15-20 kgf / cm.
