Description

矿物纤维组合物
本发明涉及一种可生物降解的矿物纤维组合物。
现有技术描述了一些所谓可生物降解的矿物纤维组合物。
矿物纤维组合物的可生物降解性非常重要，因为各种研究指出，在小于3微米范围内，直径很小的矿物纤维是致癌的，而如此直径的可生物降解的矿物纤维则显示出较低致癌性，或没有致癌性。
但是，不仅是生物降解性，矿物纤维或由其生产的产品的机械性能和热性质，以及矿物纤维组合物的加工性能同样也是非常重要的。例如，矿物纤维在很大程度上被用于绝缘。特别在工业领域内的这种应用，需要矿物纤维具有足够的温度稳定性。
此矿物纤维组合物也必须是可加工的，能通过已知方法，如喷射法，生产出直径很小的矿物纤维。
本发明以上述问题为着眼点，提供了一种新的矿物纤维组合物，该组合物以生物降解性为特点，有良好的温度稳定性，并易于加工。
本发明以发现由一种矿物纤维组合物能解决这个问题为基础，该组合物基本上由氧化硅，氧化钙，氧化镁及氧化钠组成。
已发现，这种矿物纤维组合物实现了所需性质，即生物降解性，温度稳定性和良好的加工性能的结合。
本发明目的是提供一种可生物降解的矿物纤维组合物，由下列组分的重量百分数来表征：
SiO2                                          50-65
A12O3                                        少于2
CaO                                             16-30
MgO                                             4-15
Na2O                                           8-20
K2O                                            0-2
B2O3                                          0-10
TiO2，Fe2O3，Cr2O3，BaO，MnO，P2O5      0-5
本发明的矿物纤维组合物是可经喷射法或旋转法拉伸的。得到的纤维具有良好的温度稳定性。很令人惊奇的是，此矿物纤维组合物显示了生物降解性。纤维的平均直径优选小于或等于10微米，特别是在2.5和5微米之间。
本发明的矿物纤维组合物优选含有如下重量百分数的组分：
SiO2                                           55-65
Al2O3                                         少于1.5
CaO                                              16-25
MgO                                              5-15
Na2O                                            9-15
K2O                                             少于2
B2O3                                           0-8
TiO2，Fe2O3，Cr2O3，BaO，MnO，P2O5       0-5
特别是，本发明的矿物纤维组合物含有如下重量百分数的组分：
SiO2                                       55-59
Al2O3                                     少于1.5
CaO                                          18-23
MgO                                          8-12
Na2O                                        9-13
K2O                                         少于1
B2O3                                       0-3
TiO2，Fe2O3，Cr2O3，BaO，MnO，P2O5   0-3
氧化镁的含量优选6-12重量％，特别优选8-12重量％。
氧化铬的含量优选少于1.5重量％，特别优选少于1.0重量％。
氧化硼的含量优选少于4重量％。
为评估生物降解性，采用了德国玻璃学会(German GlassSociety)的标准粉末试验。这是易于实行的方法，并且能对生物降解性充分测量。在L.Springer“Laboratoriumsbuch für dieGlasindustrie”，第3版，1950，Halle/s：W.Knapp Verlag中描述了此法。
通过瑞典法检测此矿物纤维的温度性能。此法运用了一个碳化硅管炉，它具有两端开口的水平工作管，长350mm，内径27mm。炉中央有一个小的陶瓷托盘(30×20×3mm)，用来盛装试验样品。试验样品三维尺寸是12×12×12mm或12mmφ×12mm高。容积密度一般为100Kg/m3。以5K/min升温。通过读数镜片连续检测试验样品高度的改变。
下列将参考实例，更详细地描述本发明。
                      实例1
生产了以重量百分数计具有如下组成的矿棉：
SiO2                       56
Al2O3                     0.5
CaO                          20
MgO                          10
Na2O                        10
B2O3                       2.7
此组合物在拉伸温度为1330℃下，通过喷射法能被很好地加工成平均直径为2.5微米的矿物纤维。
按照德国玻璃学会(German Glass Society)的标准粉末试验检测得到测试值为35mg/kg，此值代表了高生物降解性。
通过瑞典法检测温度性能，得到温度稳定性是：620℃下，高度减少5％，这能通过单张附图的实例显示的相应图中清晰看出。
                      实例2
生产了以重量百分数计具有如下组成的矿棉：

CaO                  21           21.20
MgO                  11           15.45
Na2O                11           10.05
在拉伸温度为1310℃下，通过喷射法，此组合物能很好地被加工成平均直径为2.7微米的矿物纤维。
按照德国玻璃学会的标准粉末试验检测得到测试值为37mg/kg，此值代表了高生物降解性。
通过瑞典法检测温度性能，得到温度稳定性是：600℃下，高度减少5％。
