Abstract

The invention relates to the technical field of ceramic glazes and discloses a Longquan celadon glaze with super hydrophobicity and low expansibility. The Longquan celadon glaze is prepared from the following raw materials in parts by weight: 20-30 parts of Longyan kaolin, 8-10 parts of violet gold clay, 12-16 parts of potash feldspar, 30-35 parts of lithium frit, 15-20 parts of a composite binder, 5-10 parts of barium carbonate, 8-12 parts of quartz and 4-7 parts of SiO2 micro-sized particles. A physical method and a chemical modification method are combined, and the prepared ceramic glaze has super hydrophobicity.

Description

technical field [0001] The invention relates to the technical field of ceramic glazes, in particular to a low-expansion Longquan celadon glaze with superhydrophobic properties. Background technique [0002] Ceramic products are known as a new type of "green jewelry" because of their shape, glaze color and wonderful artistic conception contained in decorations. Ceramic jewelry has the characteristics of easy access to raw materials, high plasticity, large design space, healthy and natural, corrosion resistance, and Low temperature, low cost and other characteristics, these characteristics make ceramic jewelry have a lot of room for development in the future. Ceramic products placed outdoors are easily contaminated with dust particles. When it rains, the dust particles on the ceramic products will easily accumulate together along the rainwater. After the rain, the water on the ceramic products will gradually evaporate, and the accumulated dust particles will It will solidify ...
