FIBREGLASS, PREPARATION METHOD THEREFOR AND FIBREGLASS COMPOSITE

摘要: Disclosed in the present invention are a fibreglass, preparation method therefor and fibreglass composite. The has nominal diameter range of 3 micrometers to 15 micrometers. deviation value is ±15% diameter. In by weight percent, content aluminium oxide 20%-33%; silicon 4.11 - 5.48 times calcium oxide; 0.9 -2.1 magnesium oxide. Since this can produce new product nature having performance an eutectoid aluminium, silicon, calcium, under condition containing high (the thereof 20%-33% or 23%-33% 25%-33%), overcome difficulties prior art caused increasing viscosity glass, namely inability control melting bubble quality; also lead technical effect both significant energy saving with consumption reduction, reduction carbon emission relatively low devitrification temperature which facilitates production large amount, yet no pollutant boron poison gas environment occurs during production.
