Abstract

The invention discloses a light thermal insulation ceramic product and a preparation method thereof. The ceramic product comprises the following raw materials in parts by weight: 30-40 parts of kaolin, 25-35 parts of perlite, 20-28 parts of obsidian, 12-18 parts of vermiculite, 12-15 parts of biotite, 8-10 parts of aluminium oxide, 8-15 parts of rare earth oxide, 10-15 parts of anion powder, 15-21 parts of hollow glass beads, 12-18 parts of waste ceramic residues and 3-5 parts of auxiliary, wherein the auxiliary comprises acrylic resin, dibutyl phthalate, stearic acid and sodium humate. The ceramic product prepared with a scientific raw material formula has low coefficient of thermal conductivity and excellent thermal insulation property, can also release anions and is healthier and more environment-friendly.

Description

technical field [0001] The invention belongs to the field of ceramic products, and in particular relates to a lightweight heat-insulating ceramic product and a manufacturing method thereof. Background technique [0002] China is one of the first countries in the world to use ceramics. Because of its hard texture, fineness, high temperature resistance, and rich glaze colors, ceramics are widely used in food utensils, decoration, science and other fields. However, ordinary ceramic products generally have the disadvantages of high thermal conductivity and poor heat insulation effect. Improving the thermal insulation performance of ceramic products is not only the focus of foreign material fields, but also the direction of joint research by material scientists in my country. [0003] On the other hand, with the development of society and the improvement of people's living standards, more and more attention is paid to environmental protection and health, especially in daily nece...
