Abstract

The invention relates to the field of glass wool, and provides a preparation method of sound-insulation and heat-insulation superfine glass wool fiber, the sound-insulation and heat-insulation superfine glass wool fiber is prepared from molten raw materials through a centrifugal fiber forming machine at the fiber forming temperature of 980-1000 DEG C and the centrifugal speed of 2600-2800r / min; the raw materials comprise the following components in percentage by weight: 3-8% of fluorite; 7-12% of borax; 45-55% of quartz sand; 2-4% of dolomite; 30-40% of cullet; and 2-4% of sodium carbonate. The method is simple in process, high in yield, uniform in glass fiber distribution and high in fiber strength.

Description

Technical field [0001] The present invention relates to the field of glass wool, and more particularly to a method of preparation of a sound insulation superfine glass cotton fiber. Background technique [0002] CN201210259367.6 discloses a centrifugal ultra-fine glass wool, which is: 63.0 ~ 66.5% SiO2, 1.4 ~ 3.0% Al2O3, 5.5 ~ 7.5% CaO, 1.5 ~ 3.0% MgO, 0.4 ~ 1.3% k2O, 14.2 ~ 16.0% Na2O, 5.5 ~ 7.6% B2O3. The Al2O3 content is 1.4 ~ 3.0%, which can reduce the crystallization of the glass liquid, so that the fibers are flexible, burdle and break; the B2O3 content is 5.5 to 7.6%, and the viscosity of the glass is lowered at 1050 ± 10 ° C. Fiber is easy to refine. The glass wool fiber diameter is 90% in a positive distribution of 2 to 4 μm, and the fiber length is 92% in a positive distribution at 2 to 3 cm. The present invention also discloses the preparation method of the above-mentioned ultrafine glass wool, selecting the material that meets the required material, and puts the feeds...
