Description
技术领域
本发明属于玻璃制备的技术领域,提供了一种电磁屏蔽隔音玻璃及制备方法。
背景技术
随着现代建筑以及工业迅速猛进,普通平板玻璃已经落后于新型市场的需求,科学不断发展使得玻璃不满足于只是被采光与隔断。玻璃要不断向多功能方向发展,需要在原片玻璃的基础上后续改良。玻璃深加工后的产品具有控制光线、调节温度、防止噪音、电磁屏蔽和提高建筑艺术装饰等功能,实现了玻璃已不再只是采光材料,而且是现代建筑的一种结构材料和装饰材料。
隔音是玻璃的一项基本功能,其原理为:室外各种声源产生振动发出噪音,噪音通过空气介质进行传播,当噪音传递到隔音玻璃门窗上,再经隔音玻璃逐次衰减,特别是噪音在经过隔音阻尼胶时,中频噪音和高频噪音被隔音阻尼胶吸收、扭曲、减震、衰减,能将中、高频噪音有效地滤除,进入室内的噪音就会显著减少,进而达到减轻噪声污染的目的。
另外,电磁屏蔽玻璃是一种防电磁辐射,抗电磁干扰的透光屏蔽器件,涉及光学、电学、金属材料、化工原料、玻璃、机械等诸多领域,广泛用于电磁兼容领域。主要解决电子***与电子设备间的电磁干扰,防止电磁信息泄漏,防护电磁辐射污染;有效保障仪器设备正常工作,保障机密信息的安全,保障工作人员身体健康。现代多功能玻璃的发展和应用,要求玻璃具备多项功能,因此将隔音、电磁屏蔽等功能集于一体的新型多功能玻璃在当今社会发展中扮演着重要角色。
中国发明专利申请号201610101788.4公开了一种建筑玻璃,包括铝合金框架、第一铝合金条、第二铝合金条和间隔条,第一铝合金条、第二铝合金条和间隔条均安装于铝合金框架上,第一铝合金条和第二铝合金条与铝合金框架之间均设置有钢化玻璃,钢化玻璃与铝合金框架之间均设置有防水泡棉胶,第一铝合金条和第二铝合金条均为中空设置,第一铝合金条内部填充有硅酸铝纤维,第二铝合金条内部填充有聚酯纤维隔音棉,间隔条内部为蜂窝结构,间隔条与第一铝合金条之间设置有电磁屏蔽透明膜,第二铝合金条和间隔条之间设置有高透明抗紫外线胶片。该发明的缺陷是玻璃结构复杂,填充材料分布不均,电磁屏蔽和隔音效果一般。
中国发明专利申请号201620237865.4公开了一种能有效降低电磁辐射污染的Low-E玻璃,包括从上至下依次设置的第一铜导电漆层、第一玻璃基层、隔音胶片层、中空铝条层、第二玻璃基层、防潮层、Low-E低辐射节能玻璃层、第二铜导电漆层;Low-E低辐射节能玻璃层包括从下到上依次设置的第三玻璃基层、第二Si3N4膜层、第三AZO膜层、第四Cu膜层、第五NiCr膜层、第六AZO膜层、第七Si3N4膜层、第八AZO膜层、第九Ag膜层、第十NiCr膜层、第十一TiO2膜层、第十二SiNx膜层和第十三Sic膜层。该发明的缺陷是玻璃结构复杂,制备难度大,电磁屏蔽和隔音效果依然有待加强。
综上所述,现有技术中的新型玻璃,单一的隔音或电磁屏蔽玻璃的应用范围有限,而将隔音、电磁屏蔽等功能集于一体的新型多功能玻璃,往往存在结构复杂、功能性填料分散不均的问题,导致功能效果不佳,制备工艺复杂而成本较高,制约了新型玻璃的发展应用,因此开发一种具有优异电磁屏蔽性能和隔音效果的玻璃,有着重要的意义。
发明内容
可见,现有技术的玻璃具有难以兼顾电磁屏蔽性能和隔音效果,且传统多功能玻璃的制备工艺复杂、成本较高的缺点。针对这种情况,我们提出一种电磁屏蔽隔音玻璃及制备方法,有效实现了优异的电磁屏蔽和隔音性能,同时玻璃质轻而成本低廉。
为实现上述目的,本发明涉及的具体技术方案如下:
一种电磁屏蔽隔音玻璃的制备方法,所述电磁屏蔽隔音玻璃制备的具体步骤如下:
(1)将蛇纹石与聚乙烯醇的水溶液按比例加入球磨机中,将蛇纹石磨成细粉的同时,聚乙烯醇分子链嵌入蛇纹石的结构中,出料后加入羰基镍粉和镀银铜粉,并在超声辅助下加压使羰基镍粉和镀银铜粉进入蛇纹石的片层间,然后过滤、干燥,再与聚甲基丙烯酸甲酯在混炼机中进行混炼,制得热塑性的电磁屏蔽填料;
(2)将步骤(1)制得的电磁屏蔽填料与增塑剂、发泡剂、聚乙烯醇缩丁醛混合均匀,经塑化挤压成型制得发泡胶片;
(3)以步骤(2)制得的发泡胶片为中间层,以聚甲基丙烯酸甲酯为上下层,进行热压复合,制得三层结构的电磁屏蔽隔音玻璃。
优选的,步骤(1)所述各原料的重量份为,蛇纹石12~15重量份、聚乙烯醇2~4重量份、水22~28重量份、羰基镍粉15~20重量份、镀银铜粉15~20重量份、聚甲基丙烯酸甲酯13~34重量份。
优选的,步骤(1)所述球磨的转速为60~80r/min,时间为12~15h,球料比为2:1~3:2。
优选的,步骤(1)所述加压的压力为2~4MPa,时间为10~20min。
优选的,步骤(1)所述混炼的温度为120~130℃,时间为8~15min。
优选的,步骤(2)所述增塑剂为邻苯二甲酸二正辛酯、邻苯二甲酸二仲辛酯、邻苯二甲酸二环己酯、邻苯二甲酸二丁酯中的至少一种。
优选的,步骤(2)所述发泡剂为甲醇、乙醇、丙酮、丁酮中的一种。
优选的,步骤(2)所述各原料的重量份为,电磁屏蔽填料10~30重量份、增塑剂2~5重量份、发泡剂1~3重量份、聚乙烯醇缩丁醛62~87重量份。
优选的,步骤(3)所述热压复合的温度为110~115℃,压力为3~6MPa,保压时间为5~10s。
本发明还提供了一种上述制备方法制备得到的电磁屏蔽隔音玻璃。所述电磁屏蔽隔音玻璃是通过将羰基镍粉和镀银铜粉负载于蛇纹石的片层间,并通过将聚乙烯醇分子链嵌入蛇纹石的结构中,再与聚甲基丙烯酸甲酯混炼,制得热塑性填料,进一步与聚乙烯醇缩丁醛制备发泡胶片,再与聚甲基丙烯酸甲酯层热压复合而制得。
本发明提供了一种电磁屏蔽隔音玻璃及制备方法,与现有技术相比,其突出的特点和优异的效果在于:
1.本发明制备的电磁屏蔽隔音玻璃,采用的电磁屏蔽填料的成本较低,通过在铜粉表面镀银,可防止铜粉的氧化,并与羰基镍粉协同使用,可达到良好的电磁屏蔽效果。
2.本发明的制备方法,通过在蛇纹石的结构中引入聚乙烯醇分子链,并在电磁屏蔽填料负载于蛇纹石片层之后,与聚甲基丙烯酸甲酯进行混炼,使聚乙烯醇与聚甲基丙烯酸甲酯的链间形成氢键等作用,将电磁屏蔽填料包覆于结构中,并使蛇纹石的表面由亲水性转变为亲油性,促进蛇纹石与聚乙烯醇缩丁醛基体的界面结合,带动镀银铜粉和羰基镍粉在胶片层中的均匀分散。
3.本发明的制备方法,在聚乙烯醇缩丁醛胶片的制备过程中加入发泡剂,制得的发泡胶片层具有多孔结构,一方面明显提高聚乙烯醇缩丁醛胶片层的隔音效果,另一方面可降低密度,减轻玻璃重量。
4.本发明的制备方法,以蛇纹石作为镀银铜粉和羰基镍粉的载体,由于蛇纹石本身的结构特点,可起到提高玻璃的隔热效果和隔音效果的作用。
