Description

一种增强玻璃棉吸声性能的方法
技术领域
本发明属于吸声材料领域，具体涉及一种增强玻璃棉吸声性能的方法。
背景技术
随着人类社会的不断发展与进步，工业化水平的提高，人类所生活的环境中也充斥着越来越多的噪音污染。人长期受到噪音污染影响，轻则睡眠质量、注意力、记忆力下降，重则破坏人类神经，造成精神疾病。因此对环境中的噪音污染进行管控刻不容缓。影响多孔材料吸声性能的因素主要有材料流阻、孔隙率、材料厚度和堆密度。本发明充分利用这些影响玻璃棉吸声性能的因素，采用不同容重的玻璃棉叠加，可有效提高玻璃棉的吸声性能。
专利CN108912664A公开了一种改性玻璃棉增强吸声材料的制备方法，其制备过程大致如下：(1)制备稀土该性的玻璃棉纤维：(2)制备活化改性胶粉；(3)按配方比例将聚醚多元醇、泡沫稳定剂、AK-8805、三乙烯二胺、一氟二氯乙烷、活化改性胶粉、十二烷基硫酸钠、改性玻璃棉纤维和改性矾土混合均匀，然后加入异氰酸酯，室温搅拌熟化即可制备出改性玻璃棉。该型改性玻璃棉虽然可以提高吸声性能，但是制备过程复杂且成本较高。
专利CN109081633A公开了一种玻璃棉基高强度防水吸声材料及其制备方法，由以下原料制备而成：玻璃棉40-60份、介孔分子筛10-20份、氧化铝纤维6-15份、二氧化硅气凝胶5-12份、硅烷偶联剂3-8份、二硫化铂2-10份、氧化石墨烯4-8份、聚氨醋8-16份、发泡剂3-6份、椰油酸二乙醇酞胺2-5份、八甲基环四硅氧烷7-14份、甲基硅醇钠盐8-15份、抗氧化剂4-10份、水15-40份。该吸声材料具有良好的机械强度、吸声效果，但该专利未考虑有效吸声频段和吸声频段范围。
发明内容
为了满足社会对于隔音吸音材料的需求，本发明提供了一种增强玻璃棉吸声性能的方法。
一种增强玻璃棉吸声性能的方法，采用两种不同规格的超细玻璃棉，规格A和规格B，其中规格B玻璃棉2片，规格A玻璃棉1片；将规格A玻璃棉置于两片规格B玻璃棉之间，并使用胶黏剂使其固化成型。
进一步地，所述规格A容重为80-125kg/m3，厚度为5-15mm，宽度为0.2-1m；规格B容重为30-60kg/m3，厚度为5-15mm，宽度为0.2-1m。
进一步地，所述胶黏剂采用热固性酚醛树脂胶黏剂。
进一步地，所述固化成型工艺中固化温度为280-320℃，固化时间为2-3分钟。
有益效果：本发明与现有技术相比，具有以下优点：将规格B的玻璃棉置于上下表面，规格A的玻璃棉置于中间位置，这样声波先透过孔隙率较为密集的规格B棉片，其中一部分声波通过与空隙中空气摩擦、粘滞作用，使声能逐渐转变成热能散失，声波穿过阻抗不同的玻璃棉也会消耗部分声能，从而有效提高玻璃棉的吸声性能。这种玻璃棉制作过程简便，可设计性强，成本较低，可根据噪音等级设计不同规格的增强吸声性能的玻璃棉。
附图说明
图1为本发明所述一种增强吸声性能的玻璃棉结构示意图；
图示10为规格A玻璃棉，20为规格B玻璃棉。
具体实施方式
下面结合具体实施例，进一步阐明本发明，应理解这些实施例仅用于说明本发明而不用于限制本发明的范围，在阅读了本发明之后，本领域技术人员对本发明的各种等价形式的修改均落于本申请所附权利要求所限定。
实施例1
预先制备两种不同规格的玻璃棉，规格A容重为80-125kg/m3，厚度为5mm，宽度为0.5m；规格B容重为30-60kg/m3，厚度为5mm，宽度为0.5m。然后将规格A的玻璃棉置于两片规格B玻璃棉之间，采用压力泵将热固性酚醛树脂胶黏剂均匀喷洒到组合体上，然后将其放入固化炉固化2-3分钟，固化温度为280-320℃，制备出S1型玻璃棉。
实施例2
预先制备3片规格B玻璃棉，规格B容重为30-60kg/m3，厚度为5mm，宽度为0.5m。然后将规格B玻璃棉进行简单叠加，采用压力泵将热固性酚醛树脂胶黏剂均匀喷洒到组合体上，然后将其放入固化炉固化2-3分钟，固化温度为280-320℃，制备出S2型玻璃棉。
通过对实施例进行比较，S1型玻璃棉的吸声性能最好，不仅对高频有较好的吸声性能，对中低频也有较好的吸声性能。
上述仅为本发明的两个具体实施方式，但本发明的设计构思并不局限于此，凡利用此构思对本发明进行非实质性的改动，均应属于侵犯本发明保护的范围的行为。但凡是未脱离本发明技术方案的内容，依据本发明的技术实质对以上实施例所作的任何形式的简单修改、等同变化与改型，仍属于本发明技术方案的保护范围。
