Description

矿物纤维组合物
本发明涉及一种能生物降解的矿物纤维组合物。
现有技术描述了一些据说能生物降解的矿物纤维组合物。
矿物纤维组合物的生物降解性是十分重要的,因为许多研究都指出:直径很小,小于3微米的矿物纤维可能是致癌的,而同样直径的能生物降解的矿物纤维无致癌性。
然而,矿物纤维组合物也必须是容易由已知方法,特别是喷射法处理以制备小直径矿棉。这尤其意味着玻璃熔体一种足够大的处理范围,例如80℃和合适的粘度。
而且矿物纤维或由它制成的产品的机械和热性能极为重要。例如,矿物纤维常大量用作绝缘目的。特别是用于工业方面,需要矿物纤维具有足够的耐热性。
本发明主要提供一种新的矿物纤维组合物,其特征是能生物降解,耐热性好且易于加工。
本发明主要基于下列发现:矿物纤维组合物主要含有氧化硅、碱土金属氧化物,也含有氧化钠和/或氧化钾作为熔融加速剂和大量氧化铝来增加耐热性,可解决上述问题。
已经证明,这样的矿物纤维组合物能完全具备所需的性质,即生物降解性,用于工业绝缘的耐热性和良好的加工性,以生产矿棉等产品。这同时意味着熔体的失透性温度上限优选低于1300℃。平均纤维直径有效10微米或更小,尤其为2.5~5微米。
本发明的目的是一种能生物降解的矿物纤维组合物,它以下列组成(按重量百分数)为特征:SiO2               40~<52
    Al2O3             <4CaO                 >25,≤45MgO                 5~15BaO                 0~7Na2O               2~12K2O                0~10Na2O+K2O         2~15TiO2,Fe2O3,MnO 0~5
本发明的矿物纤维组合物尤其可用喷射法拉制,即得到细粒低渣矿棉。
该矿物纤维耐热性至少为730℃。
该矿物纤维具有生物降解性。
加入氧化钠和/或氧化钾可降低熔点,因而改进熔融过程中的加工性。而且,若矿棉组合物中含有钠,则将有利于使用最高达35%的碎废玻璃。
本发明的矿物纤维组合物优选在由矿物燃料,特别是以天然气为燃料的熔炼室内,于1350~1450℃熔炼。这类熔炼室可生产均匀熔体,这是生产质量恒定产品的先决条件。玻璃熔体的均匀性也有助于成纤过程的重复性,因而有助于产品的热性能和机械性能。而且,这样生产出的矿棉的恒定化学组成导致可控的生物降解性。
加入氧化铝尤其能增加矿棉的耐热性。
本发明矿物纤维组合物最好具有下列组成(以重量百分数计):SiO2              40~51.5Al2O3            2~<4CaO                 25.5~40MgO                 8~15
    BaO                 0~5
    Na2O              3~8
    K2O               2~10
    Na2O+K2O        5~10
    TiO2,Fe2O3,MnO 0~3
氧化硅的含量为40~55%(重量)特别优选。
关于碱性氧化物,特别优选5~8%(重量)。氧化铝的含量优选3~4%(重量)。
可用于代替氧化钙或氧化镁的氧化钡的含量≤7%(重量),优选≤5%(重量),特别是0.5~3%(重量)。
氧化钠含量优选>2%(重量)。
氧化铝含量为1~2%(重量),特别是1.5%(重量)也特别优选。
铁的含量优选0.5~2.5%(重量)。
为评估生物降解性,使用德国玻璃学会的标准粉末试验。这种方法容易进行,当使用模拟生理肺呼吸装置流体于37℃时可给生物降解性给出足够的量度。该方法描述于L.Springer,"Laboratoriumsbuch fur die Glasindustrie",第3版,1950,Halle/S:W.Knapp Verlag。
该矿物纤维的温度行为由“Swedish method”法测定。此法中使用带两端开口的水平工作管的碳化硅管式炉,工作管长350mm,内径27mm。炉中心有小片陶瓷托板(30×20×3mm)用以支持试样。试样尺寸为12×12×12mm或12mmφ×12mm高。堆密度通常为100kg/m3。温升为5K/min。试样高度的变化由读数镜片连续测定。
参考实例,下面将对本发明做更详细的描述。
                  实例1
生产有下列组成(以重量百分数计)的矿棉组合物:
      SiO2               51Al2O3             3
      Fe2O3             0.3CaO                 31MgO                 10Na2O               5
      K2O                0.1
此组合物可用喷射技术,在1300~1400℃拉伸温度下,很好加工成平均直径为2.0~10微米的矿物纤维。
按德国玻璃学会的标准粉末研究,得到40mg/Kg的值,因而具有高的生物降解性。
由Swedish method法对温度行为的测定,得到在735℃时耐热性下降5%,这可从单次拉制举例所示的相应图上清楚看出。
               实例2
生产有下列组成(以重量百分数计)的矿棉组合物:SiO2         46.5
     Al2O3       3.5CaO            35MgO            10Na2O          5
此组合物可用喷射技术,在1300~1400℃拉伸温度下,很好加工成平均直径为2.0~10微米的矿物纤维。
接德国玻璃学会的标准粉末研究,得到35mg/Kg的值,因而具有高的生物降解性。
由Swedish method法对温度行为的测定,得到在800℃时耐热性下降5%。
本例表明,氧化铝含量高的玻璃具有优良的耐热性,这本身又是产品耐燃性的标准。
