Изобретение относитс к переработке отходов полимерных материалов в частности подвулканизованных резиновых смесей.The invention relates to the processing of waste polymeric materials, in particular, pre-cured rubber compounds.
Цель изобретени - повышение стой- кости резиновой смеси к подвулкани- зации и интенсификаци процесса пластификации .The purpose of the invention is to increase the resistance of the rubber mixture to scorchization and intensify the plasticization process.
Способ осуществл ют следующим образом.The method is carried out as follows.
Подвулканизованную резиновую смесь (рецептура приведена в табл.1) измельчают совместно с фенолформаль- дегидной смолой (3-15 мае.ч.) на измельчителе ударно-режущего дей- стви типа ДКУ-М с классификационной решеткой с отверсти ми диаметром 10 мм. При однократном пропуске цолучают полидисперсную крошку с размером частиц 2-10 мм. Пластификацию провод т обработкой на лабораторных вальцах.The pre-vulcanized rubber mixture (the recipe is given in Table 1) is ground together with a phenol-formaldehyde resin (3-15 parts per hour) on a DKU-M type impact-cutting grinder with a 10 mm diameter grating. At a single pass, a polydisperse crumb is produced with a particle size of 2-10 mm. Plasticization is carried out by processing on laboratory rollers.
В Качестве смолы используют и - трет-бутилфенолформальдегидную смолу (фенофор Б). Далее определ ют про- должительность пластификации до получени смеси с пластичностью 0,4 по ГОСТ 415-754; врем до начала подвул- кайизации получаемого пластиката (ГОСТ 10722-76), усгловную прочность при раст жении, относительное удлинение . Смесь вулканизуют дл определени физико-механических характеристик вулканизата при 143 С в течение 25 мин (смесь 1) и 40 мин (смесь 2). As a resin, it is used and - tert-butylphenol-formaldehyde resin (phenophore B). Next, determine the duration of plasticization to obtain a mixture with a plasticity of 0.4 according to GOST 415-754; the time before the start of sub-vulcanization of the resulting plastic (GOST 10722-76), the ultimate tensile strength, and the relative elongation. The mixture is vulcanized to determine the physicomechanical characteristics of the vulcanizate at 143 ° C for 25 minutes (mixture 1) and 40 minutes (mixture 2).
Результаты испытаний приведены вThe test results are given in
табл. 2.tab. 2
В табл. 3 приведена продолжительность вальцевани до получени смеси с пластичностью 0,4 в зависимости от температуры вальцов (количество добавл емой смолы 3,0 мае.ч.).In tab. Figure 3 shows the duration of rolling to obtain a mixture with a plasticity of 0.4, depending on the temperature of the rollers (the amount of resin added is 3.0 parts by weight).
