Description

一种防辐射橡胶地板的加工方法
技术领域
本发明涉及橡胶地板领域,尤其涉及一种防辐射橡胶地板的加工方法。
背景技术
橡胶地板是天然橡胶、合成橡胶和其它成分的高分子材料所制成的地板。现有的操场很多都是橡胶材料。橡胶地板质感也是像橡胶一样柔软,当别人在运动踏在橡胶地板上,会有无限的动力和弹跳力,非常适合运动作为运动场合的铺垫。现有的大部分的橡胶地板暴露于室外,需要具有良好的耐酸碱和抗氧化能力,同时受到阳光的照射,可能导致寿命降低。现有的橡胶地板并不能够很好的满足上述要求。
废旧橡胶颗粒作为填料不仅节约了成本,而且挥发物少,对健康有益,所以在橡胶地板中加入废旧橡胶颗粒,不仅健康环保,而且成本低,本发明公开了用废旧橡胶制作橡胶地板技术内容。
发明内容
本发明目的就是为了弥补已有技术的缺陷,提供一种防辐射橡胶地板的加工方法。
本发明是通过以下技术方案实现的:
一种防辐射橡胶地板的加工方法,步骤为:
(1)将废橡胶经破碎分离后得橡胶颗粒,与纳米钛酸钡混合均匀,得粉末;
(2)将一半的丁基橡胶送入炼胶机中进行炼胶,炼胶温度为120-130℃,时间为13-15min,取出与乙酸乙酯混合,搅拌浸泡至丁基橡胶溶解,再与所述粉末混合均匀,喷雾干燥,去除乙酸乙酯得到混合物料;
(3)将剩余丁基橡胶与所述混合物料、填料、增塑剂、抗静电剂、抗氧剂、促进剂、防老剂在密炼机上进行密炼,密炼温度为135-155℃,密炼时间为17-19min,然后进行开炼,开炼温度为80-90℃,开炼时间为23-27min;
(4)将开炼后的炼胶在三辊延压机上进行延压成胶片;
(5)将所述胶片在温度为185-195℃、压力为20-30MPa的情况下进行硫化成型,硫化时间12-15min,即得所需防辐射橡胶地板。
废橡胶颗粒的细度为300-600目,废橡胶颗粒与纳米钛酸钡的质量比为8-10:1。
步骤(2)中,丁基橡胶:乙酸乙酯:所述粉末的质量比为16-18:70-80:30-35。
步骤(3)物料的质量份数为:剩余丁基橡胶16-18份、所述混合物料36-43份、填料10-13份、增塑剂1-1.5份、抗静电剂0.6-0.8份、抗氧剂0.5-0.7份、促进剂7-9份、防老剂2-2.3份。
延压辊筒温度为70-80℃。
所述胶片厚度为2-4cm。
本发明的优点是:本发明橡胶地板使用了废橡胶,减少了环境污染;将废橡胶颗粒与纳米钛酸钡混合,纳米钛酸钡均匀吸附在橡胶颗粒表面,提高了橡胶颗粒的耐磨性、抗老化性,提高了地板的强度、耐久性,还具有防辐射性能。本发明用丁基橡胶制成溶液与废橡胶颗粒均匀混合,再进行喷雾干燥,使得丁基橡胶均匀包裹在废橡胶颗粒表面,提高了相容性,使得地板的强度大大提高。
具体实施方式
