Abstract

The invention discloses biosoluble ultrafine glass wool and a preparation method thereof. The biosoluble ultrafine glass wool comprises the following chemical components by mass: 60-68 parts of SiO2,0 to 3 parts of Al2O3, 6 to 12 parts of CaO and MgO, 15 to 20 parts of Na2O and K2O, 4 to 4.9 parts of B2O3, 3 to 5 parts of BaO, and no more than 4 parts of Fe2O3, SO3, ZrO2 and CeO2, wherein the content of CeO2 is not less than 0.5 part. The biosoluble ultrafine glass wool has good biosolubility and thermal insulation properties; the ultrafine glass wool has a small fiber diameter and a low thermal conductivity (wherein thermal conductivity at room temperature can be as low as 0.03 W / (m.K)), and is good in heat preservation effect; once the glass wool is inhaled into a respiratory system byan organism, or even enters the lung, the half-life of the glass wool is less than 40 days, and the glass wool can be quickly dissolved by the lung fluid of the organism and does not cause any inflammation.

Description

technical field [0001] The invention relates to a glass wool and a preparation method thereof, in particular to a biosoluble ultrafine glass wool and a preparation method thereof. Background technique [0002] At present, fire-proof porous inorganic fiber thermal insulation materials, such as glass wool, mineral wool and rock wool, have been widely used in thermal insulation and energy-saving fields such as heat pipes, home appliances, refrigeration, construction and industry. Traditional inorganic fiber materials belong to SiO 2 、Al 2 o 3 It is a silicate fiber, which has excellent thermal insulation performance, chemical stability and corrosion resistance. However, the diameter of the fiber is small, so it is easily inhaled into the lungs by the human respiratory system during production and use, and cannot be completely dissolved after a long time, thus posing a potential threat to human health. In 2001, the International Agency for Research on Cancer (IARC) carried o...
