Keywords:
полиуретанизоцианурат (ПУИЦ), 2,4-толуилендиизоцианат (2,4 ТДИ), утандиол (1, 4-БД), 2,3- бутиленгликоль (2,3- БГ), монопропиленгликоль (1,2 -ПГ), polyurethane izotsianurat (PUITS), 2,4- toluilendiizotsianat (2,4 TDI), 1,4-butanediol (1,4-BD), 2,3-butanediol (2,3 - BG), propylene glycol (1,2-PG)
Abstract (English):
The effect of 1,4-BD, 2,3-BG and 1,2-PG and the ratio of NCO: OH on the physico-mechanical properties of PUITS is investigated. The influence of the structure and concentration of diol on the effective density of the grid PUITS is studied. The maximum of strength properties with retention of satisfactory elasticity corresponds to the effective density of a grid ~ 4,5×10 2 to mol/m 3 at a concentration 2,75mol of 1,4-BD, 2,25 mol of 2,3-BG and 2 mol of 1,2 PG is shown.
