Description
Известен способ получени термостойких самосмазывающихс антифрикционных материалов на основе твердых смазок с использованием в качестве св зующего фенолфталеинфенолформальдегидного олигомера и наполнител с последующим отверждением.
В предлагаемом способе дл обеспечени большей износостойкости изделий при высоких температурах в качестве св зующего примен ют полученные по реакции полициклотримеризации олигомерные соединени полифенилена , содержащие этинильные группы и имеющие следующее строение:
КЛ
X-Cs Ш
Х- CsCR
где X -алкилен, фениле.
А--/V:; X
R - Н, фенил,
а также
п 1-500, отверждаемые в присутствии различных типов наполнителей, количество которых в смеем с твердой смазкой может составл ть 0,5-97 вес. % от веса композиции .
Реакци полициклотримеризации останавливаетс на стадии получени олигомерных
полифениленов различного молекул рного веса , которые могут быть расфракционированы. В данных олигомерных производных имеютс новые 1,2,4- и 1,3,5-замещенные фенильные дра.
В получаемых олигомерных соединени х полифенилена при температуре выще 70-200°С после перехода в расплавленное состо ние происход т дальней.щие химические превращени , привод щие к нолучению трехмерной
ствне даже больших количеств наполнител не оказывает отрицательного вли ни иа отвержление синтезнруемых олнгомерных соелииеннн полифенн.тена.
Дл реалнзацнн иреллагаемого нзобретен и нредварительно получают гомогенную смесь олнгомерного соединени нолифенилена и наполннтел , прнчем нолнау -омогеннзаци может быть доетнгнута как сухим, так л мокрым способамн.
По сухому способу смешенне осущеетвл ете в мельшщах обычного и вибрационного типа , иа вальцах iriH в смеентел х роторного 1ииа.
Отверждение ирессовочной массы с целью получени сформованных образцов, обладающих высокой термо-, тенло- н водостойкостью, а также необходимым комплексом физико-мехаи ичсскнх показателей, ировод т ири 130- 500С и давлении 50-1000 кг./см- в нресс-формах закрытого тина.
