Problems solved by technology

[0006] 1. Due to the pores generated by foaming, the flexural strength and compressive strength are low, and high porosity and strength cannot be taken into account;
[0007] 2. The thermal conductivity is large, the heat insulation effect is not good, and even when it is filled with boiling water, it is easy to burn the user;
[0008] 3. The sintering process is not easy to control, and defective products are prone to appear

Abstract

The invention discloses a light-heat conduction and lightweight porous ceramic for daily use. The light-heat conduction and lightweight porous ceramic for daily use is prepared from, by weight, 60-70parts of lithium feldspar powder, 14-20 parts of lithium bentonite powder, 8-13 parts of bauxite powder, 6-11 parts of gamma-alumina, 12-18 parts of quartz powder, 5-9 parts of aluminum silicate fibertubes, 70-90 parts of water, 0.9-1.5 parts of a water reducer, 1.8-3.4 parts of a foaming agent, 1.1-1.7 parts of a foam stabilizer and 2-4.5 parts of a dispersant. The above formula is optimized tomake the pores in the ceramic product for daily use uniform and dense, so the ceramic product for daily use has a low heat conduction coefficient and a good heat insulation property, can effectively avoid users from being burnt when used, and is well received by consumers; and the ceramic product for daily use has the advantages of good balance between high porosity and strength, portability during use, and good durability.

Description

technical field [0001] The invention relates to the field of daily-use ceramic products, in particular to a light-weight porous daily-use ceramic with low thermal conductivity and a preparation method thereof. Background technique [0002] The production of daily-use ceramics can be said to be due to people's needs for daily life. In daily life, people have the most contact with and are most familiar with porcelain, such as tableware, tea set, coffee set, wine set, and table set. [0003] The development and application of lightweight ceramic production technology can not only reduce the use of raw materials for ceramic bodies, but also effectively reduce the consumption of various electricity and fuels in ceramic production. The lightweight production of ceramics has become an effective way to reduce pollution, save land resources and save energy. The lightweight production of ceramics can not only reduce the volume density of ceramics, facilitate long-distance transportat...
