Description
Изобретение относитс к способу получени мьтированных полимерных пленок, примен емых, например, дл чертежных работ , при. светокопировании.The invention relates to a method for producing mt-sized polymer films used, for example, for drawing works, with. blueprint.
Известен способ попучени матированной пОпиэтилентерефталатной (ПЭТФ) пленки путем обработки поверхности двухосно-ориентированной пленки водным раствором ги дроокиси щелочного металла при температуре С с последующей промывкой пленки водой и сущкой. При использовании известного способа происходит потер веса пленки на 20-ЗО%.There is a known method for spreading a matted polyethylene terephthalate (PET) film by treating the surface of a biaxially oriented film with an aqueous solution of alkali metal hydroxide at a temperature C followed by washing the film with water and substance. When using the known method, the weight loss of the film is 20%.
Цель изобретени - улучшить чертежнографические свойства пленки.The purpose of the invention is to improve the drawing properties of the film.
Сущность данного изобретени сводитс к тому, что обработке подвергают поверхность аморфной (невыт нутой) пленки и после промывки осуществл ют ее двухосную ориентацию.The essence of the present invention is that the surface is treated with an amorphous (non-extruded) film and, after washing, is biaxially oriented.
iTaK гор чим водным раствором гидро окиси натри или гидроокиси кали обраб ,тыввют аморфную ПЭТФ пленку (заготовку дл получени двухосноориентированной ПЭТФ пленки). Прозрачна и гл нцева поверхность аморфной пленки после обработки приобретает матово-шероховатый вид. Это свойство поверхности сохран етс на после ее двухоснсй ориентации, котора производитс на обычном ориентационном оборудовании дл поииэтилентерефталата. iTaK with a hot aqueous solution of sodium hydroxide or potassium hydroxide is processed to form an amorphous PET film (a billet to obtain a biaxially oriented PET film). The transparent and glossy surface of the amorphous film after processing takes on a dull-rough appearance. This property of the surface is retained after its biaxial orientation, which is carried out on conventional orientation equipment for polyethylene terephthalate.
Матирование аморфной ПЗТФ пленки водным раствором гидроокиси натри и Гидроокиси кали проводитс при следук щих режимах;Matting of an amorphous PZTP film with an aqueous solution of sodium hydroxide and potassium hydroxide is carried out under the following conditions;
Концентраци гидроокиси натри или кали в рас40- .60 творе, вес,% 110-130The concentration of sodium hydroxide or potassium in 40-. 60 solution, weight,% 110-130

П р и М 8 р . Аморфную ПЭТФ пленку выдерживают в водном растворе гидроокиси натри прИ 120 С в течение 2-3 мин, затем промывают в воде и высушивают . Ориентацию ее провод т при режиме , аналогичном режиму ориентации необработанной аморфной ПЭТФ пленки.Pr and M 8 p. The amorphous PET film is kept in an aqueous solution of sodium hydroxide at a temperature of 120 ° C for 2-3 minutes, then washed in water and dried. Its orientation is carried out in a mode similar to the orientation mode of the raw amorphous PET film.
