Description

一种环保型再生橡胶制备方法 技术领域
本发明涉及橡胶材料制备领域，尤其是一种环保型再生橡胶制备方法。
背景技术
在天然橡胶资源日趋减少和能源相对紧缺的今天，废旧橡胶资源化研究具有重要的现实意义，生产再生胶是废旧橡胶循环利用的有效手段。
CN101220178A提供一种可以提高再生橡胶抗拉强度并能有效去除其难闻气味的再生橡胶制备方法。其是把废旧硫化橡胶粉碎后进行磁选分离得胶粉，再动态脱硫、精炼而成，动态脱硫步骤时，每100g胶粉中，加入妥尔油12.3－15.0g、煤沥青6.6－8.1g、De－Link助剂0.53－0.64g、松香1.64－2.0g、水9.8－12.0g，蒸汽压力0.6－1.0MPa、保温时间20－40分钟。
CN104629137A公开了一种再生橡胶的制备方法，涉及再生胶生产技术领域。本发明再生橡胶的制备方法为：清洗废旧橡胶，晾干，切胶，粉碎，过分子筛，得到橡胶粉；将一定质量的N-甲基二乙醇胺和苯系物混合均匀，然后加入氧化铁，保温，得到脱硫剂；将橡胶粉转入超声波萃取仪中，然后逐滴加入脱硫剂和软化剂，搅拌均匀，超声波辅助脱硫，将所得产物压片，即得到再生胶。该发明采用超声波辅助脱硫剂的方法进行脱硫，其作用温度低，避免高温易使碳-碳键断裂、使再生胶的性能下降的缺点，脱硫时间短，脱硫效果好、再生胶性能优良。
CN107417964A公开了一种再生橡胶制备方法，将98-102重量份废旧轮胎胶粉、4-8重量份再生活化剂、6-12重量份石蜡油和1-4重量份抗老化剂混合均匀，加入到反应釜中反应，反应温度为120-160℃，反应时间为2-4小时；再进行密炼，密炼温度为130-190℃，时间为8-12分钟，转速为60-100转/分钟。该发明所述再生橡胶制备方法，成本低，回收利用率高，采用该方法得到的再生橡胶具有优良的抗老化性能和力学性能。
再生胶作为填充剂在生胶配方体系中占有重要的地位。再生胶的添加虽然会使得生胶的物理机械性能下降，但却可以提供生胶所没有的特点。再生胶的加入可缩短混炼时间，提高挤出压延的供料速度，在硫化时，再生胶可起到抗老化剂的作用，然而在生产再生胶的过程中也存在很多不足和困难。主要的再生方法如水油法，动态连续脱硫法等生产过程污染大、时间长、耗能高；此外，现在广泛应用的再生活化剂如多烷基苯酚二硫化物等有一定的毒性。无论是从全球发展态势还是生态环境承载能力看，我国都无法继续靠这种粗放式的方法实现资源高效利用和循环利用。
