Abstract
Изобретение относитс к термической обработке в маслах изделий из полиамидов. Изобретение позвол ет на 40-45°/о повысить физико-механические свойства и па 2 балла улучшить биостойкость материала за счет того, что в способе поверхностпой обработки полиамидов путем термической обработки в маслах, содержащих биоциды, об- .работку провод т в течение 3 ч при в среде, состо щей из индустриального масла и медных солей синтетических жирных кислот фракции в массовом соотношении 10:1 в присутствии 1 мас. /о триэ- тиленгликол .This invention relates to heat treatment in oils of polyamide products. The invention allows to increase the physical and mechanical properties by 40-45 ° C and by 2 points to improve the biostability of the material due to the fact that in the method of surface treatment of polyamides by heat treatment in oils containing biocides, the treatment is carried out when in an environment consisting of industrial oil and copper salts of synthetic fatty acids fraction in a mass ratio of 10: 1 in the presence of 1 wt. / about triethylene glycol.

Изобретение относитс к термической обработке в маслах изделий из полиамидов.This invention relates to heat treatment in oils of polyamide products.
Целью изобретени в. улучшение физико-механических свбйств и биостойкости нолиамидрв.The purpose of the invention. improvement of physical and mechanical properties and biostability of nolyamidrv.
Пример 1. Пластины из антифрикционного самосмазывающегос материала (АСМ К-1 12) на основе капролона обрабатывают 3 ч при 130±3°С в среде, включающей ин- дустриальное масло, медные соли синтетических жирных кислот фракции (получены обработкой 50%-ного раствора натриевых солей жирных кислот 25°/о-ным раствором сульфата меди) в массовом соотно- шении 10:1 и триэтиленгликоль (1 мас.°/о на сумму компонентов в среде). Полученные образцы имеют разрущающее напр жение при раст жении 72 МПа, разрушающее напр жение при сжатии 156 МПа, коэффициент трени при скорости движени 1,5 м/мин 0,089, набухаемость 0,36%, водопоглощение 3,30/0 и биостойкость (поГОСТ 9049-65, метод Б) О баллов.Example 1. Caprolon-based antifriction self-lubricating material (AFM K-1 12) plates are treated for 3 hours at 130 ± 3 ° C in medium containing industrial oil, copper salts of synthetic fatty acids fractions (obtained by treating a 50% solution sodium salts of fatty acids 25 ° / o with a solution of copper sulfate) in a mass ratio of 10: 1 and triethylene glycol (1 wt. ° / o for the sum of the components in the medium). The obtained samples have a tensile stress at a stretch of 72 MPa, a breaking stress at compression of 156 MPa, a coefficient of friction at a speed of movement of 1.5 m / min, 0.089, a swelling capacity of 0.36%, a water absorption of 3.30 / 0, and biostability (POGST 9049 -65, method B) About points.
Пример 2 (известный). Пластины из .материала АСМ К-112 обрабатывают 5 ч при 150°С в среде полиэтилсилоксановой жидкости , содержащей тетрафторборат аммони в массовом соотношении 10:1. Образцы имеют разрушающее напр жение при раст жении 40 МПа, разрущающее напр жение при сжатии 110 МПа, коэффициент трени 0,121, набухаемость 0,52%, водопоглощение 4,6% и биостойкость 2 балла.Example 2 (known). Plates of AFM K-112 material are treated for 5 hours at 150 ° C in an environment of polyethylsiloxane liquid containing ammonium tetrafluoroborate in a mass ratio of 10: 1. Samples have a tensile stress of 40 MPa, tensile compressive stress of 110 MPa, a friction coefficient of 0.121, a swelling capacity of 0.52%, a water absorption of 4.6%, and a biostability of 2 points.
