为解决橡胶易老化，抗磨性能差的问题，并且能够吸声的效果，本发明提出了一种低蛋白吸声橡胶，其组分如下：50-60份氯化丁基橡胶、2-4份发泡剂、6-10份蛋白酶、3-8份纳米材料、4-15份聚芳醚砜酯、6-9份防老剂。
本发明的优选方案，所述发泡剂为二亚硝酸五亚甲基四胺。
本发明的优选方案，还包括5份硬脂酸。
本发明的优选方案，所述蛋白酶为碱性蛋白酶。
本发明的优选方案，所述防老剂为N-苯基-α-苯胺。
本发明的优选方案，所述纳米材料为SiC纳米材料。
为得到本发明公开的一种低蛋白吸声橡胶，提出的制备方法，同时将50-60份氯化丁基橡胶、2-4份发泡剂、6-10份蛋白酶置于电动搅拌机内，保持60摄氏度进行搅拌，搅拌时间为30分钟，静置1小时后，加入6-9份防老剂、3-8份纳米材料、4-15份聚芳醚砜酯，继续搅拌2小时，逐渐形成固体状；将所得混合物放入烘干机，最终获得产物。
优选的，在搅拌的同时加入5份硬脂酸。
本发明的有益效果是：本发明提出的橡胶吸声效果好，不易老化，使用时间长，并且拉伸效果好，并且降低了橡胶内的蛋白质含量，使其耐磨性能增加。
具体实施方式
结合实施例，对本发明进一步进行详细说明，
实施例1
