Biosoluble antibacterial ultrafine glass wool and preparation method thereof

Abstract

The invention discloses biosoluble antibacterial ultrafine glass wool and a preparation method thereof. The biosoluble antibacterial ultrafine glass wool comprises the following chemical components bymass: 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, 0 to 3 parts of ZnO, 0 to 6 parts of Ag2O, 4 to 8 parts of B2O3, and no more than 3 parts of Fe2O3, SO3, ZrO2 and CeO2, wherein the content of CeO2 is not less than 0.5 part. The biosoluble antibacterial ultrafine glass wool has good biosolubility, bacteriostatic effect and thermal insulation properties.

Description

technical field [0001] The invention relates to a glass wool and a preparation method thereof, in particular to a biosoluble antibacterial 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 (I...

Problems solved by technology

[0010] In the article "Man-made mineral fibers such as glass fiber and glass wool and human health" published in the journal "Glass Fiber" in 2002, it was pointed out that introducing ultra-fine glass fibers with a diameter of 1.5 μm and a length >4 μm into the pleura and peritoneum would increase the incidence of tumors. Therefore, it may pose a certain potential danger to human health

These products basically belong to the categories of European Union Class 2 "probable carcinogen" and Class 3 "probable carcinogen", which pose a potential threat to the safety of production personnel and users.
