Исследование фосфорилирования и озонирования измельченной резины

Article preview

Исследована модификация измельченной резины изношенных покрышек под действием перок- сифосфорной кислоты и озоновоздушной смеси. Получены продукты с фосфорно-кислыми, карбок­сильными и карбонильными группами в структуре. Полная статическая обменная емкость фосфори- лированной крошки достигает 2,88 мг-экв/г, озонированной - 0,58 мг-экв/г, привитых на озонирован­ную крошку сополимеров - 4,8 мг-экв/г.

Research of sulfidation and hydrosulfidation processes of rubber crumbs

Article preview

In order to find new directions for the use of polymeric material of worn rubber products, the hydrosulfidation of crushed rubber of automobile tire treads was carried out by two methods: polysulfidation followed by desulfidation with alkali and interaction with hydrogen sulfide. According to the first variant the content of mercaptogroups reaches 10%, according to the second variant at atmospheric pressure and room temperature up to 0.6%, at overpressure up to 1 atm 1.5%. It is shown that at treatment with hydrogen sulfide both physical absorption and chemisorption take place. The data on influence of temperature on speed of sorption of gaseous hydrogen sulfide are received.
