Problems solved by technology

[0002] The total area of ​​various buildings in my country has exceeded 40 billion square meters, and the area of ​​newly completed houses is 1.8-2.2 billion square meters every year. Most of the exterior walls of the buildings have not been treated with heat insulation. Therefore, heat insulation ceramics Bricks are popular because of their low thermal conductivity, high strength, fire resistance, resistance to rainwater penetration, and durability. However, the current production of heat-insulating ceramic tiles has low porosity, heavy weight, and poor heat preservation effect, which cannot really be realized. The purpose of heat preservation and energy saving

Abstract

The invention provides a phase change heat storage light porous ceramic tile. The ceramic tile is prepared from, by weight, 50-80 parts of ceramic tile raw materials, 14-20 parts of diatomite, 10-30 parts of lignin, 2-4 parts of sodium tripolyphosphate, 7-13 parts of calcium carbonate, 6-10 parts of expanded perlite, 14-20 parts of paraffin and 6-10 parts of glass bead powder. The ceramic tile prepared according to the proportion of the raw materials and through the preparation method has high porosity and compressive strength and is low in weight and good in heat preservation effect; the compressive strength can reach 10 Mpa or above.

Description

technical field [0001] The invention relates to the field of building heat preservation, in particular to a lightweight porous ceramic brick for phase change heat storage. Background technique [0002] The total area of ​​various buildings in my country has exceeded 40 billion square meters, and the area of ​​newly completed houses is 1.8-2.2 billion square meters every year. Most of the exterior walls of the buildings have not been treated with heat insulation. Therefore, heat insulation ceramics Bricks are popular because of their low thermal conductivity, high strength, fire resistance, resistance to rainwater penetration, and durability. However, the current production of heat-insulating ceramic tiles has low porosity, heavy weight, and poor heat preservation effect, which cannot really be realized. The purpose of heat preservation and energy saving. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art ...
