Description
技术领域
本发明属于吸声新材料技术领域,尤其涉及一种阻燃柔性吸声材料及其制备方法和应用。
背景技术
目前国内声屏障的吸声材料主要是超细玻璃棉、岩棉等无机纤维类多孔吸声材料,这类材料吸声性能非常好,但由于此类材料质轻、性脆、易折断飞扬,对施工人员刺激性大,容易造成皮肤瘤痒、刺红。再者,如果用于象声屏障这样的立面结构,由于材料下沉,容易出现漏声现象,影响使用效果。所以无机纤维类多孔吸声材料虽然仍在使用,但从长远的眼光看其使用必然要受到很大程度的限制。为了改进玻璃棉、岩棉、矿棉等传统多孔吸声材料的缺点,泡沫玻璃、泡沫金属等泡沫类多孔吸声材料,以及多孔陶瓷、多孔石膏等颗粒类吸声材料得到了迅速的发展,但上述材料治理重且吸声效果较差。因此需要开发出轻质环保的新型吸声材料。
发明内容
本发明要解决的技术问题是克服现有技术的不足,提供一种重量轻、吸声效果好、强度高、阻燃和抗老化性能好、可折叠和收卷的阻燃柔性吸声材料,还相应提供该阻燃柔性吸声材料的制备方法及应用。
为解决上述技术问题,本发明采用以下技术方案:
一种阻燃柔性吸声材料,包括以下重量份的组分:
无卤素橡胶25~40份,
无卤素塑料15~25份,
增强纤维2~10份,
重质粉体5~10份,
发泡剂10~20份,
塑化剂10~20份,
阻燃剂5~10份,
稳定剂1~2份,
促进剂1~2份,
硫化剂1~2份,和
偶联剂1~2份。
上述的阻燃柔性吸声材料,优选的,所述增强纤维为铝纤维、碳纤维、聚酯纤维、硅酸盐纤维中的一种或多种。
上述的阻燃柔性吸声材料,优选的,所述重质粉体为超细石墨烯粉体、超细三氧化二铝粉体、超细铁粉体中的一种或多种;所述重质粉体的粒径为100nm~100μm。
上述的阻燃柔性吸声材料,优选的,还包括:杀菌剂1~2份。
上述的阻燃柔性吸声材料,优选的,所述无卤素橡胶为硅橡胶、顺丁橡胶、三元乙丙橡胶中的一种或多种;所述无卤素塑料为聚碳酸树酯、聚丙烯、聚乙烯、聚氨酯中的一种或多种。
上述的阻燃柔性吸声材料,优选的,所述发泡剂为碳酸氢铵、偶氮二异丁腈、偶氮二甲酰胺中的一种或多种;所述阻燃剂为氢氧化铝、氢氧化镁、硼酸锌中的一种或多种;所述塑化剂为邻苯二甲酸二丁酯、邻苯二甲酸二辛酯、己二酸二辛酯中的一种;所述稳定剂为钙锌粉、有机锡、有机锑中的一种;所述促进剂为二硫化二苯并噻唑、N-环已基-2-苯并噻唑次磺酰胺、四甲基二硫化秋兰姆中的一种;所述硫化剂为升华硫、氧化锌、氧化镁中的一种或多种;所述偶联剂为铬络合物偶联剂、硅烷偶联剂、钛酸酯偶联剂中的一种。
上述的阻燃柔性吸声材料,优选的,所述抗菌剂为纳米银、载银磷酸盐、四氯苯二腈中的一种。
作为一个总的发明构思,本发明还提供一种上述的阻燃柔性吸声材料的制备方法,包括以下步骤:
(1)先将无卤素橡胶、无卤素塑料、塑化剂、稳定剂置于开炼机中,在温度为120~180℃,速度为10~30r/min下混炼1~5min后,加入增强纤维、重质粉体、阻燃剂和偶联剂,维持温度和转速不变,混炼2~10min,冷却至室温,得到预混料;
(2)在步骤(1)所得的预混料中加入发泡剂、促进剂和硫化剂,在30~90℃,转速为10~30r/min下混炼2~10min,室温放置12~36h后,在室温转速为10~30r/min下继续混炼2~10min,最后置于平板硫化机上模压发泡成片,模压温度为120~180℃,压力为5~15MPa,时间为10~30min,室温冷却12~36h后得到硫化试样;
(3)将步骤(2)所得的硫化试样的上下表面剥离,所述上下表面剥离厚度均为1~2mm,得到柔性吸声材料中间体;
(4)对步骤(3)所得的阻燃柔性吸声材料中间体进行物理挤压,开炼机的滚轮间距为阻燃柔性吸声材料中间体厚度的1/4~2/3,室温下转速为10~30r/min,以形成表面开孔且相邻孔洞互相连通的吸声结构,得到柔性吸声材料。
上述的阻燃柔性吸声材料的制备方法,优选的,所述步骤(2)中,还包括在预混料中加入抗菌剂。
作为一个总的发明构思,本发明还提供一种上述的阻燃柔性吸声材料或上述的制备方法制得的阻燃柔性吸声材料在成型吸声构件或作为吸声构件的应用。
本发明的创新性在于:
本发明先通过发泡剂化学反应产生的气体在橡胶和塑料共混物中形成气泡,然后在材料成型后通过切片和物理挤压形成表面开孔且孔洞互相连通的吸声结构,使声能进入空洞后不断折射、反射以及摩擦生热而耗散掉。通过添加增强纤维(如为铝纤维、碳纤维、聚酯纤维、硅酸盐纤维等)和重质粉体(如石墨烯、三氧化二铝、铁粉等),既能增加材料的密度,同时分散在混料中的增强纤维和超细粉体能形成多层不同界面的声反射,增加了声能量的消耗,因此能进一步提高材料的吸声量,突破“质量定律”。同时因为增强纤维的添加,通过增强纤维形成的交联网状结构,提升了材料的抗压和抗拉性能好。而且相比泡沫玻璃、泡沫金属等吸声材料,本发明的材料具有良好的粘弹性,可更好的消耗声能。而且本发明中的材料均不含卤素,通过添加无毒的阻燃剂来达到自熄灭效果,不会在燃烧时产生有毒的黑烟,因此防火性能也得到大幅提高。
与现有技术相比,本发明的优点在于:
1、本发明的阻燃柔性吸声材料,无卤素橡胶和塑料共混物为复合基体,以纤维增强剂和重质粉体为辅助填料,添加发泡剂形成吸声通道,以阻燃剂、塑化剂、稳定剂、促进剂、硫化剂、偶联剂、杀菌剂为主要助剂,所成型的阻燃柔性吸声材料所成型的阻燃柔性吸声材料具有重量轻、吸声性能好,且能方便进行折叠和收卷等优点,燃烧后无有毒黑烟,所成型的吸声构件和降噪设施易于安装和拆卸,尤其适用于需要快速安装和拆卸的使用环境;同时还具有阻燃、抗老化性能好、抗压和抗拉性能好等优点。
2、与常规化学方法和物理方法相比,本发明的柔性吸声材料的开孔制备方法,避免了额外增加发泡剂或外加气体等,采用剥离挤压工艺,剥除了表面致密层后,通过适当的机械压力挤压,既能破坏孔间薄弱部位形成通孔,又能不完全破坏材料联结结构而使材料破碎,因而能简单方便的实现通孔吸声结构,能显著提高吸声效果。
