Abstract

Изобретение относитс  к области удалени  покрытий на основе эпоксидных и полиуретановых клеев и компаундов с различных изделий Изобретение позвол ет повысить эффективность удалени  покрыти  за счет композиции состава диметил- формамид от 35 до 40 мае % ксилол от 3 до 40 мае % в сочетании с от 24 до 27 мае % диоксана 1 таблThe invention relates to the field of removal of coatings based on epoxy and polyurethane adhesives and compounds from various products. The invention improves the removal efficiency of the coating due to the composition of the composition dimethylformamide from 35 to 40 May% xylene from 3 to 40 May% in combination with from 24 to 27 May% dioxane 1 tabl

Description

Изобретение относитс  к составам дл  удалени  полимерных покрытий, в частности покрытий на основе эпоксидных и полиуретановых клеев и компаундов.The invention relates to compositions for removing polymeric coatings, in particular coatings based on epoxy and polyurethane adhesives and compounds.

Цель изобретени  - повышение эффективности удалени  покрытий на основе эпоксидных и полиуретановых клеев и компаундов .The purpose of the invention is to increase the removal efficiency of coatings based on epoxy and polyurethane adhesives and compounds.

В таблице представлены примеры, иллюстрирующие изобретение.The table shows examples illustrating the invention.

Смесь диметилформамида, ксилола, диоксана представл ет собой азеотропную смесь, кип щую npnt 102°C. Реакци  растворени  полиуретановых компаундов идет при нагревании до 80-85°С. Реакци  деполимеризации клеевой пленки начинаетс  после 20-30-минутного воздействи  температуры .A mixture of dimethylformamide, xylene, dioxane is an azeotropic mixture boiling with npnt 102 ° C. The dissolution reaction of polyurethane compounds takes place when heated to 80-85 ° C. The depolymerization of the adhesive film starts after a 20-30 minute exposure to temperature.

Работа по расклейке узлов и деталей проводитс  в химическом боксе с выт жкой, скорость выт жки 1 м/с. Операционный работник пр мого контакта со смесью не имеет. Открытого испарени  смеси не допускаетс .The work of putting up knots and parts is carried out in a chemical box with a draw; the speed of drawing is 1 m / s. The operating officer has no direct contact with the mixture. Open evaporation of the mixture is not allowed.

По истечении ориентировочною времени расклейки 6-8 ч (до полного растворени  полиуретанового компаунда или эпоксидного ) смесь сливаетс  в сборник отходов ПВЖ дл  утилизации Расклеенные детали промывают изопропиловым спиртом который также сливаетс  в сборник отходов ЛВЖAfter an estimated decoupling time of 6-8 hours (until the polyurethane compound or epoxy compound is completely dissolved), the mixture is discharged into the waste collection container for recycling. The glued parts are washed with isopropyl alcohol, which is also discharged into the waste collection mixture

Claims (1)

Расклеенные узлы и детали подвергаютс  контролю и запускаютс  в повторное производство . Разова  порци  смеси, примен ема  при расклейке составл ет 100-120 мл. Формула изобретени  Состав дл  удалени  полимерного покрыти , включающий диметилформамид и ксилол, отличающийс  тем, что, с целью повышени  эффективности удалени  покрытий на основе эпоксидных и полиуретановых клеев и компаундов, он дополнительно содержит диоксан при следующем соотношении компонентов, мае %The glued-up units and parts are inspected and put into re-production. A single portion of the mixture used for sticking is 100-120 ml.
