A thermal regeneration method of waste rubber, comprises: adding a feedstock of waste rubber raw powder, environmentally-friendly softener and powdery adjuvant into an agitating heater, wherein the weight ratio thereof is 100 / 8~15 / 20~1500, firstly heating under oxygen insulation condition, then introducing into an agitating cooler and cooling to 100°C or less, discharging so as to obtain the product; or a part or all of powdery adjuvant in the feedstock is not added to the agitating heater together with other components in the feedstock at the same time, but is added to the agitating heater before discharging the feedstock which was added to the agitating heater previously, and/or is added while introducing the heated feedstock into an agitating cooler; or introducing a pre-formulated feedstock into a screw extruder, cooling the feedstock to 100°C or less after passing the heating section, mixing section, then discharging so as to obtain the product. Optionally, the said thermal regeneration method has multi-direction transfer relationship on feedstock and energy with well-known pyrolysis of waste rubber or plus a process for preparing carbon black from the flammable fuel or flammable gas.
一种废橡胶热再生方法,包括将由废橡胶生粉、环保型软化剂和粉状助剂组成的原料加入到搅拌加热器中,其中重量比为 100 / 8~15 / 20~1500,首先在隔氧条件下加热,然后导入搅拌冷却器中冷却至 100°C 或以下,排出,得到产品;或不将原料中的部分或全部粉状佐剂与原料中的其他成分同时加入搅拌加热器,而是在排出之前加入搅拌加热器的原料之前加入搅拌加热器,和/或在将加热后的原料引入搅拌冷却器时加入;或将预配制的原料引入螺杆挤压机,在通过加热段、混合段后将原料冷却至 100°C 或以下,然后排出,从而获得产品。可选地,所述热再生方法与众所周知的废橡胶热解或加上从易燃燃料或易燃气体制备
炭黑的工艺具有原料和能量的多向传递关系。
