Description
技术领域
本发明涉及隔音棉制造技术领域，具体涉及一种PVC阻燃双组分隔音棉及其制备方法。
背景技术
噪声污染是人类生活环境的大公害，它不仅严重损害我们的听觉神经，心血管系统以及神经系统，并且还能加快建筑物、工业机械的老化，影响仪器的精密度和使用年限。随着大家对噪声控制问题的日益重视，各种各样隔音降噪的方法也随之诞生。而传统的隔音材料—玻璃棉因其存在着诸多缺陷，如降噪系数低、使用寿命短、不环保、容易造成二次污染等问题，其运用受到限制，已经淡出市场而为新型吸声材料所替代。纤维类吸声材料可以在较宽的频带内有良好的隔音效果，因此可以替代以离心玻璃棉为代表的传统多孔隔材料等，这种同时具备环保、可重复利用、装饰功能、以及优越声学性能的隔音材料将会越来越多地得到市场的认可。
另一方面，随着生活实用和消防安全要求的日益增加，人们对于隔音棉的阻燃要求也越来越高。目前阻燃技术已进入一个新的发展阶段，未来吸音材料的阻燃技术正朝着高效、经济、环保的方向发展。由于无机阻燃剂具有：毒性低，热稳定性好；不析出，有持久的阻燃效果；不产生腐蚀性气体；价格低廉；较小的发烟量等优点，因此无机阻燃剂在各个方面的应用正逐步取代有机阻燃剂，因此合成无机阻燃剂的研究意义重大；但是由于有机阻燃剂目前仍在大量使用，将无机阻燃剂与有机阻燃剂组合使用不失为一种可取的过渡的方式。
目前，社会对隔音材料的需求量迅猛增长，传统的隔音材料已无法满足人们对环保性、装饰性、阻燃性的更高要求；而且一般的隔音棉的拉伸强度并不好，在拉伸过程中容易断裂，或形成裂纹，影响隔音棉的使用。因此，研究并开发应用新的高拉伸强度的环保隔音阻燃材料已成为努力的新方向。
发明内容
本发明为了解决上述的技术问题，提供一种PVC阻燃双组分隔音棉及其制备方法，将具有隔音作用的双组分棉和其他隔音降噪材料进行组合，并塞入道弹性体中，通过PVC阻燃避免隔音棉引发火灾，能够有效解决隔音降噪阻燃防火的问题。
为实现上述技术目的，本发明的技术方案是这样实现的：
一种PVC阻燃双组分隔音棉，隔音棉从上到下依次包括有PVC阻燃层、皮质缓冲层、弹性缓冲层、上双组分棉层、多孔蜂窝隔音层、隔音板层、下双组分棉层、弹性缓冲层、隔音网孔层、隔音基板层和可撕胶连接层；隔音基板层上设置有竖直向上的固定刺突，所述皮质缓冲层上设置有竖直向下的固定连接杆，弹性缓冲层的内部设置有若干根弹性加强筋，弹性加强筋将弹性缓冲层分割为不同的腔室，腔室内部均匀填装有中间的隔音板层、多孔蜂窝隔音层和设置在两端的上双组分棉层和下双组分棉层并形成隔音棉基层，隔音棉基层贯穿弹性加强筋，隔音网孔层的开设有隔音网孔道，隔音网孔道相互交错且不贯穿隔音网孔层，固定刺突的头部穿过隔音网孔层伸入到弹性缓冲层的下部、固定连接杆穿过皮质缓冲层伸入到弹性缓冲层的上部，并与弹性缓冲层固定连接。
一种基于上述的PVC阻燃双组分隔音棉的制备方法，具体包括有以下步骤：
S1.压合：将上双组分棉层、多孔蜂窝隔音层、隔音板层、下双组分棉层依次堆叠，置于模压机下在50-150℃下热压，热压持续时间为10-30min，降温至常温持续压合10-15min，将四层压合复合为一体得到隔音棉基层，并对基层进行修剪成型；
S2.成型：将弹性缓冲层的组成物料升温至200-300℃熔融，并通过特定模具浇筑得到弹性缓冲层，并将得到的隔音棉基层内嵌于弹性缓冲层中，于模压机下持续压合，使得隔音棉基层与弹性缓冲层压合成型不滑脱；
S3.固定：在步骤2得到的弹性缓冲层的上表面贴附皮质缓冲层，并将固定连接杆穿过皮质缓冲层插入到弹性缓冲层中，将皮质缓冲层固定在弹性缓冲层上；
在弹性缓冲层的下表面贴附隔音网孔层，并将带有固定刺突的隔音基板层穿过隔音网孔层将固定刺突插入到弹性缓冲层中，将隔音网孔层、隔音基板层固定在弹性缓冲层上；
再将最终得到的复合多层置于模压机下压合，将固定刺突和固定连接杆牢牢插入到弹性缓冲层中但不贯穿弹性缓冲层，形成隔音棉半成品；
S4.涂附：在步骤3得到的隔音棉半成品的上表面涂附PVC阻燃剂形成PVC阻燃层，PVC阻燃层覆盖皮质缓冲层上的固定连接杆，得到隔音棉成品，在对成品进行修剪、打磨和热封边即可得到PVC阻燃双组分隔音棉。
本发明的有益效果：本发明PVC阻燃双组分隔音棉通过加PVC阻燃材料涂附在隔音棉表面，能够有效阻燃防火，保护内层的隔音棉材料，通过将具有隔音效果的双组分棉塞入到弹性体中，在吸收汽车发动或制动产生的振动外还能够有效吸收噪音，起到很好的隔音降噪作用，采用可撕结构，使得隔音棉能够简单地从骑车内衬上拆装，以实现隔音棉的更换，通过压合的方式将隔音棉各层复合一体，并通过设置刺突和连接杆将隔音棉内层牢牢固定不滑脱，通过简单合理的科学设计，有利益提高隔音棉的隔音效果和工作效力，大大提高了隔音棉市场应用前景和价值，具有明显的实用性。

进一步地，隔音板层3、多孔蜂窝隔音层1和设置在两端的上双组分棉层2和下双组分棉层4贯穿弹性加强筋6及由其分割的腔室。
基于上述实施例给出一种PVC阻燃双组分隔音棉的制备方法，包括有以下步骤：
S1.压合：将上双组分棉层2、多孔蜂窝隔音层1、隔音板层3、下双组分棉层4依次堆叠，置于模压机下在50-150℃下热压，热压持续时间为10-30min，降温至常温持续压合10-15min，将四层压合复合为一体得到隔音棉基层，并对基层进行修剪成型；
S2.成型：将弹性缓冲层5的组成物料升温至200-300℃熔融，并通过特定模具浇筑得到弹性缓冲层5，并将得到的隔音棉基层内嵌于弹性缓冲层5中，于模压机下持续压合，使得隔音棉基层与弹性缓冲层5压合成型不滑脱；

将弹性缓冲层5内部的多孔蜂窝隔音层1、上双组分棉层2、隔音板层3和下双组分棉层4置于弹性缓冲层5与皮质缓冲层8之间，并进行压合，使得弹性缓冲层5内部出现空腔，固定连接杆14贯穿多孔蜂窝隔音层1、上双组分棉层2、隔音板层3、下双组分棉层4皮质缓冲层8与弹性缓冲层5固定连接，同样具有很好的隔音消音效果。
本发明PVC阻燃双组分隔音棉通过加PVC阻燃材料涂附在隔音棉表面，能够有效阻燃防火，保护内层的隔音棉材料，通过将具有隔音效果的双组分棉塞入到弹性体中，在吸收汽车发动或制动产生的振动外还能够有效吸收噪音，起到很好的隔音降噪作用，采用可撕结构，使得隔音棉能够简单地从骑车内衬上拆装，以实现隔音棉的更换，通过压合的方式将隔音棉各层复合一体，并通过设置刺突和连接杆将隔音棉内层牢牢固定不滑脱，通过简单合理的科学设计，有利益提高隔音棉的隔音效果和工作效力，大大提高了隔音棉市场应用前景和价值，具有明显的实用性和创造性。
尽管已经示出和描述了本发明的实施例，对于本领域的普通技术人员而言，可以理解在不脱离本发明的原理和精神的情况下可以对这些实施例进行多种变化、修改、替换和变型，本发明的范围由所附权利要求及其等同物限定。
Claims (5)
1.一种PVC阻燃双组分隔音棉及其制备方法，其特征在于，所述隔音棉从上到下依次包括有PVC阻燃层(7)、皮质缓冲层(8)、弹性缓冲层(5)、上双组分棉层(2)、多孔蜂窝隔音层(1)、隔音板层(3)、下双组分棉层(4)、弹性缓冲层(5)、隔音网孔层(9)、隔音基板层(10)和可撕胶连接层(11)；

S1.压合：将上双组分棉层(2)、多孔蜂窝隔音层(1)、隔音板层(3)、下双组分棉层(4)依次堆叠，置于模压机下在50-150℃下热压，热压持续时间为10-30min，降温至常温持续压合10-15min，将四层压合复合为一体得到隔音棉基层，并对基层进行修剪成型；
S2.成型：将弹性缓冲层(5)的组成物料升温至200-300℃熔融，并通过特定模具浇筑得到弹性缓冲层(5)，并将得到的隔音棉基层内嵌于弹性缓冲层(5)中，于模压机下持续压合，使得隔音棉基层与弹性缓冲层(5)压合成型不滑脱；
S3.固定：在步骤2得到的弹性缓冲层(5)的上表面贴附皮质缓冲层(8)，并将固定连接杆(14)穿过皮质缓冲层(8)插入到弹性缓冲层(5)中，将皮质缓冲层(8)固定在弹性缓冲层(5)上；
在弹性缓冲层(5)的下表面贴附隔音网孔层(9)，并将带有固定刺突(13)的隔音基板层(10)穿过隔音网孔层(9)将固定刺突(13)插入到弹性缓冲层(5)中，将隔音网孔层(9)、隔音基板层(10)固定在弹性缓冲层(5)上；
再将最终得到的复合多层置于模压机下压合，将固定刺突(13)和固定连接杆(14)牢牢插入到弹性缓冲层(5)中但不贯穿弹性缓冲层(5)，形成隔音棉半成品；
S4.涂附：在步骤3得到的隔音棉半成品的上表面涂附PVC阻燃剂形成PVC阻燃层(7)，PVC阻燃层(7)覆盖皮质缓冲层(8)上的固定连接杆(14)，得到隔音棉成品，在对成品进行修剪、打磨和热封边即可得到PVC阻燃双组分隔音棉。
2.根据权利要求1所述的PVC阻燃双组分隔音棉及其制备方法，其特征在于，所述弹性缓冲层(5)的内部设置有若干根弹性加强筋(6)，弹性加强筋(6)将弹性缓冲层(5)分割为不同的腔室。
3.根据权利要求2所述的PVC阻燃双组分隔音棉及其制备方法，其特征在于，所述腔室内部均匀填装有中间的隔音板层(3)、多孔蜂窝隔音层(1)和设置在两端的上双组分棉层(2)和下双组分棉层(4)并形成隔音棉基层，隔音棉基层贯穿弹性加强筋(6)。
4.根据权利要求1所述的PVC阻燃双组分隔音棉及其制备方法，其特征在于，所述隔音网孔层(9)的开设有隔音网孔道(12)，隔音网孔道(12)相互交错且不贯穿隔音网孔层(9)。
5.根据权利要求1所述的PVC阻燃双组分隔音棉及其制备方法，其特征在于，所述固定刺突(13)的头部穿过隔音网孔层(9)伸入到弹性缓冲层(5)的下部、固定连接杆(14)穿过皮质缓冲层(8)伸入到弹性缓冲层(5)的上部，并与弹性缓冲层(5)固定连接。
