Abstract

The invention relates to the technical field of high-temperature coatings, in particular to novel environment-friendly glass powder added with nano-metal oxide and used for a high-temperature coatingand a preparation method thereof. In the novel environment-friendly glass powder, according to mass percent, Bi2O3 is 60-85%, ZnO is 5-20%, B2O3 is 5-30%, Sb2O3 is 0.5-5%, SiO2 is 1-10%, Al2O3 is 1-10%, TiO2 is 0.5-3%, CaO is 0.5-8%, MgO is 0.5-10%, BaO is 0.5-10%, Na2O is 0-5%, K2O is 0-5%, Li2O is 0-5%, Y2O3 is 0.5-5%, SrO is 0.5-5%. The low-temperature lead-free environment-friendly glass powder does not contain lead oxide, has low softening point, good adhesion, good chemical stability and strong moisture resistance, and can be used for high-temperature resistant coatings.

Description

technical field [0001] The invention relates to a nano-metal oxide added for high-temperature coatings, in particular to a novel environment-friendly glass powder added with nano-metal oxides for high-temperature coatings and a preparation method thereof. Background technique [0002] At present, most of the low-melting glass powders used in high-temperature coatings are lead-containing glass powders, such as PbO-B 2 o 3 -SiO 2 system or PbO-ZnO-B 2 o 3 Department of glass. The softening temperature of these glasses is less than 400°C, and the coefficient of thermal expansion is 90-100×10 -7 / ℃, good chemical stability, good deliquescence resistance. However, the lead oxide content in the glass powder is 30-80wt%, which belongs to high-lead glass. When lead-containing glass is produced, about 10-12wt% PbO enters the atmosphere through volatilization or condenses into fine dust and falls to the ground, causing pollution to the atmosphere, soil, rivers, etc. Lead-cont...
