В лабораторных услови х нроведены испытанн 1- (3,5-дн-7ре.бутил-4-окснбензнл) -3метилпиразолона-5 (Озоннна-37) и в светлых резинах, изготовленных но стандартной рецептуре на основе НК «светлый крен, с введением парафина н без нарафина.In laboratory conditions, tested 1- (3,5-dn-7re.butyl-4-oxnbenznl) -3methylpyrazolone-5 (Ozonnna-37) and in light rubber, manufactured using the standard recipe based on NK “light heel, with paraffin n without narafina.
В процессе испытаний определ лись фнзико-механнческне характеристики резин при нормальных услови х (НУ) и после старени при 90°С в течение 3, 5 и 10 сут, стойкость резин к многократному раст жению, а также озоностойкость резин. Эталонами сравнени вл лись АО-2246 и ТБТМ.During the tests, the fnziko-mechanical characteristics of rubber under normal conditions (NU) and after aging at 90 ° C for 3, 5 and 10 days, the resistance of rubber to repeated stretching, as well as the ozone resistance of rubber were determined. Reference standards were AO-2246 and TBTM.

Из данных результатов ускоренных испытаний , приведенных в табл. 1-3, следует, что;From the results of accelerated tests are given in table. 1-3, it follows that;
-но теплостойкости резины, стабилизированные озонииом-37, равноценны резинам,-but the heat resistance of rubber, stabilized by ozonium-37, are equivalent to rubber,
стабилизированным АО-2246, а но стойкости к динамическим деформаци м малой частоты превосход т их;stabilized AO-2246, but their resistance to dynamic deformations of small frequency exceeds them;
-но озоностойкости резины с нарафином, стабилизированные озонином-37, превосход т- but ozone resistance of rubber with narafin, stabilized by ozonin-37, is superior
ночтн в 2 раза резины, стабилизированные АО-2246, и не уступают резинам, стабилизированным ТБТМ.Honest 2 times rubber, stabilized by AO-2246, and not inferior to rubber, stabilized TBTM.
Таким образом, озонин-37 вл етс эффективным противостарителем резин на основеThus, ozonin-37 is an effective antioxidant for rubbers based on
ненасыщенных каучуков и рекомендуетс дл дальнейших испытаний в отраслевых институтах резиновой промышленности.unsaturated rubbers and is recommended for further testing in industry institutes of the rubber industry.
