一种再生胶的制备方法
摘要：
本发明涉及一种再生胶的制备方法，将废橡胶依次进行粉碎、滤选分离、脱硫和精炼，获得所述再生胶，所述脱硫步骤具体为：将100重量份的滤选分离后的废橡胶、10-15重量份的松香软化剂、2-3重量份的G-680再生活化剂、2-3重量份的RX-680活化剂、3-5重量份的氧化锌活化剂和1-3重量份的KH-570偶联剂混合，于压力为20-30MPa、温度为220-320℃的条件下进行脱硫处理，所述脱硫处理的时间为55-60min，然后进行精炼步骤。本发明的再生胶的制备方法具有保证门尼粘度稳定的优点。
摘要（英）：

The invention relates to a preparation method of reclaimed rubber. The reclaimed rubber is obtained by carrying out crushing, filtering and separation, desulfurization and refining on waste rubber insequence; the desulfurization step comprises the specific steps: mixing 100 parts by weight of the filtered and separated waste rubber, 10 to 15 parts by weight of a rosin softening agent, 2 to 3 parts by weight of a G-680 regeneration activating agent, 2 to 3 parts by weight of an RX-680 activating agent, 3 to 5 parts by weight of a zinc oxide activating agent and 1 to 3 parts by weight of a KH-570 coupling agent; carrying out desulfurization treatment under the conditions that the pressure is 20 to 30Mpa, the temperature is 220 to 320 DEG C and the desulfurization treatment time is 55 to 60min; then the refining step is carried out. The preparation method of the reclaimed rubber has the advantage that stable Mooney viscosity is ensured.
