Description
技术领域
本发明涉及一种高强度高伸长率高回弹的天然橡胶。
背景技术
橡胶(Rubber)是指具有可逆形变的高弹性聚合物材料,在室温下富有弹性,在很小的外力作用下能产生较大形变,除去外力后能恢复原状。橡胶属于完全无定型聚合物,它的玻璃化转变温度(T g)低,分子量往往很大,大于几十万。橡胶分为天然橡胶与合成橡胶二种。天然橡胶是从橡胶树、橡胶草等植物中提取胶质后加工制成;合成橡胶则由各种单体经聚合反应而得。橡胶制品广泛应用于工业或生活各方面。
天然橡胶分为乳胶和干胶两种形式,其中乳胶的强度、回弹、伸长等各种物理性能更好,但是成品价格较为昂贵且易造成皮肤过敏。干胶的成本更低,不易过敏但是一般而言物理性能不如乳胶,研发一种高强度、高伸长、高回弹的干胶材料配方成为研究方向。
发明内容
本发明的目的在于提供一种高强度高伸长率高回弹的天然橡胶,以解决上述背景技术中提出的问题。
为解决上述技术问题,本发明提供的技术方案为:一种高强度高伸长率高回弹的天然橡胶,包括以下重量份的原料:3号烟片橡胶0~100份、3L橡胶0~100份、CV60恒粘橡胶0~100份、氧化锌2~20份、硬脂酸0.1~3份、聚乙二醇0.2~2份、纳米碳酸钙1~20份、纳米高岭土2~15份、环烷油2~20份、硫磺0.1~2份、橡胶促进剂0.5~3份。
作为优选,一种高强度高伸长率高回弹的天然橡胶,由以下步骤制作而成:
1)把3号烟片橡胶、3L橡胶、CV60恒粘橡胶、氧化锌、硬脂酸、聚乙二醇、纳米碳酸钙、纳米高岭土、环烷油、硫磺、橡胶促进剂按顺序加入橡胶密炼机;
2)在5~50r/min转速及冷却水通量1~50m3/h下进行混炼,达到30~120min时间及100~200℃温度后排料;
3)在开炼机或双锥/双腕出片机上出片;
4)冷却;
5)重新在密炼机或开炼机上加入硫化剂并出片;
6)冷却得成品。
本发明优点在于:具有高强度、高伸长率和高回弹的特性,适合于工业化大批量生产,可根据需要做出需要的颜色和厚度,不含乳胶,不含氨,对皮肤过敏性低、刺激性低,适合制成各种对强度、伸长率、弹性、颜色要求高的橡胶制品。
