Изобретение относитс к области обработки сформованных изделий - модификации поверхности изделий из поликарбонатов.This invention relates to the field of processing molded products - surface modification of polycarbonate products.
Известен способ модификации поверхности изделий из поликарбонатов путем обработки изделий модифицирующими агентами, например смесью нескольких растворителей, при нагревании с последующей сушкой.There is a method of modifying the surface of polycarbonate products by treating the products with modifying agents, for example a mixture of several solvents, when heated, followed by drying.
Цель изобретени - снижение гидрофильНОС1И и повышение стабильности диэлектрических свойств изделий из поликарбонатов как в услови Х термоокислени , так и после выдержки в воде.The purpose of the invention is to reduce the hydrophilicity and increase the stability of the dielectric properties of polycarbonate products both under conditions of X thermal oxidation and after exposure to water.
Это достигаетс тем, что в качестве модифицирующего агента примен ют 1-6%-ный раствор пирогаллола в смеси глицерина и воды , вз тых в соотношении 1 : 6-1 : 19.This is achieved by using a 1-6% solution of pyrogallol as a modifying agent in a mixture of glycerin and water, taken in a ratio of 1: 6-1: 19.
Предложенный способ осуществл ют следующим образом.The proposed method is carried out as follows.
Образцы из поликарбоната (ПК) прогревают при 80°С в течение I-3 час в 1-6%-ном растворе пирогаллола в смеси глицерина и воды , вз тых в соотношении 1 :6-1 : 19, после чего образцы высушивают 1 час при 120°С в среде воздуха. Образцы изделий из поликарбоната , обработанные по предложенному способу , имеют свойства, указанные в таблице. 3 Предмет изобретени Способ модификации поверхности изделий из поликарбонатов путем обработки изделий Модифицирующими агентами при нагревании 5 с последующей сушкой, отличающийс 4 тем, что, с целью снижени гидрофильности и повышени стабильности диэлектрических свойств, в качестве модифицирующего агента примен ют 1-6%- ый раствор пирогаллола в смести глицерина и воды, вз тых в соотно шении 1 : 6-1 : 19.Polycarbonate (PC) samples are heated at 80 ° C for I-3 hours in a 1-6% solution of pyrogallol in a mixture of glycerin and water, taken in a ratio of 1: 6-1: 19, after which the samples are dried for 1 hour at 120 ° C in air. Samples of products made of polycarbonate, processed by the proposed method, have the properties indicated in the table. 3 Subject of the Invention A method for modifying the surface of polycarbonate products by treating the products with modifying agents upon heating 5 followed by drying, 4 characterized in that, in order to reduce hydrophilicity and increase the stability of dielectric properties, 1-6% solution pyrogallol to remove glycerin and water, taken in a ratio of 1: 6-1: 19.
