为了更好的说明本发明的效果，以下选取市面常见的作为静音层的材料作为对照例，具体如下：
对照例一
自常州绿之源高分子材料有限公司购买的降解率为90％的聚乙烯醇膜。
对照例二
自武汉市凯帝塑料制品有限公司购买的PE发泡膜。
对照例三
与实施例三的区别在于：对照例三不添加纤维。
对照例四
与实施例三的区别在于：对照例四不添加粘土。
针对实施例一至实施例五制得的环保片材，以及对照例一中的聚乙烯醇膜和对照例二中的PE发泡膜进行降解试验，试验如下：
试验一：酸降解试验
分别称量各片材的重量，将各片材分别浸入0.1mol/L的盐酸中，于室温下放置60天，取出，除去表面残留的盐酸，再次称量各片材的重量，根据如下公式计算出各片材的降解率，并记录：
降解率＝(片材初始重量-片材最终重量)/片材最终重量*100％
式中片材的重量单位为g。
试验二：碱降解试验
分别称量各片材的重量，将各片材分别浸入0.1mol/L的氢氧化钠中，于室温下放置60天，取出，除去表面残留的盐酸，再次称量各片材的重量，根据如下公式计算出各片材的降解率，并记录：
降解率＝(片材初始重量-片材最终重量)/片材最终重量*100％
式中片材的重量单位为g。
试验三：氧化降解试验
分别称量各片材的重量，将各片材分别浸入含量为30％的双氧水中，于室温下放置60天，取出，除去表面残留的盐酸，再次称量各片材的重量，根据如下公式计算出各片材的降解率，并记录：
降解率＝(片材初始重量-片材最终重量)/片材最终重量*100％
式中片材的重量单位为g。
试验一至试验三中的结果如表一：
Figure PCTCN2020080148-appb-000001
由表一可知，与对照例一与对照例二相比，实施例一至实施例五中片材的降解率均大于对照例一和对照例二，且接近于对照例一，表明本发明公开的环保片材具有较好的降解性能，对环境具有较低的影响。
试验四：隔音性能试验
根据标准号为ASTM E2179(地板覆盖物在降低穿过混凝土地面传播的碰撞声音效果的实验室测量的标准试验方法)对环保片材进行隔音性能测试，结果如表二：
Figure PCTCN2020080148-appb-000002
由表二可知，与对照例一和对照例二相比，实施例一至实施例五的隔声量均大于对照例一和对照例二，表明本发明公开的环保片材具有较优的隔音效果。
试验五：利用电动油毡不透水仪测试防水性能
(1)在系统无气泵压力的情况下，关闭放水阀8、透水盘截止阀9、10、11，打开加水阀6、放气阀7，向气液转换缸内加水至距缸顶50mm处；
(2)调节减压阀，使气压达到试验要求的压力，分别慢慢旋开透水盘截止阀9、10、11，使水缓慢充满不透水盘后关闭截止阀，然后试样放在不透水盘上，用压盖将试样固定在透水盘上，并用螺栓压紧压盖；
(3)打开电源开关，并将报警开关旋到“开”的位置，调整时间继电器至5h，分别打开截止阀、9、10、11；
(4)将计时旋钮开关置于“开”位置，开始计时，计时完毕后发出讯响信号，打开计时开关，取出试样。
判断标准：当试样出现透水现象后，电动油毡不透水仪会自动发出声光报警。
本试验针对实施例一至实施例五制得的的环保片材，以及对照例一中的聚乙烯醇膜和对照例二中的PE发泡膜各重复8次试验，记录出现的透水次数并计算透水率，透水率＝出现的透水次数/8*100％。试验结果如表三：
Figure PCTCN2020080148-appb-000003
由表三可知，实施例一至实施例五的透水率均明显低于对照例一和对照例二，表明本发明中采用聚氨酯或甲基硅酸钠作为防水剂可有效提高片材的防水性能。
试验六：拉伸性能试验
将实施例三中的片材、对照例二中的聚乙烯醇膜以及对照例三和对照例四中的片材制成厚度为0.5mm、长度为80mm、宽度为10mm，，再根据标准号GB 13022-91(塑料拉伸性能试验方法)，找出应力-应变曲线中屈服点所对应的应变值，即伸长率值，以此判断各试样的拉伸性能。试验结果如表四：
项目 对照例二 对照例三 对照例四 实施例三
L 269.4 285.4 293.7 304.5
L 0 80 80 80 80
伸长率 2.37 2.57 2.67 2.81
表四中：伸长率＝(L-L 0)/L 0*100％,式中L 0为各试样的初始长度，L为屈服点所对应的伸长。
由表四可知，与对照例二相比，对照例三、对照例四和实施例三中片材的伸长率均大于对照例二，表明本发明公开的环保片材具有较优的拉伸性能。与对照例三和对照例四相比，实施例三的伸长率均大于对照例三和对照例四，表明本发明中添加的碳纤维和粘土可有效增强片材的拉伸性能。
本具体实施方式的实施例均为本发明的较佳实施例，并非依此限制本发明的保护范 围，故：凡依本发明的结构、形状、原理所做的等效变化，均应涵盖于本发明的保护范围之内。
