Abstract

The invention discloses a ceramic material used for a building external wall. The ceramic material used for the building external wall comprises the raw materials of, by weight, 10-14 parts of polyurethane, 50-60 parts of ceramic particles, 15-19 parts of kaolin, 8-11 parts of potassium chloride powder, 10-20 parts of graphite, 11-15 parts of latex, 20-30 parts of waste shredded paper, 10-25 parts of waste straws, and 2-6 parts of kieselguhr. The fireproofing grade of the ceramic material reaches the A1 level, and the ceramic material is a high-tech novel building thermal insulation material which is low in heat conductivity coefficient, waterproof, free of toxicity, corrosion resistant, mothproof, capable of preventing ageing, free of radioactivity, insulative, staticproof, high in mechanical strength, stable in performance and capable of insulating heat and sound. In addition, energy consumption in the production process is very low, the recovery rate of waste in the producing process can reach 100%, and the ceramic material belongs to the green environmental protection industry.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a ceramic material for building exterior walls. Background technique [0002] Building energy conservation will be a key point in the development of China's construction industry in the 21st century. The current building energy consumption is huge, and the waste is seriously inconsistent with my country's current development goals. my country is a big energy-consuming country. The heating energy consumption per unit building area is about three times that of developed countries with similar climates. Building energy consumption has exceeded a quarter of the country's total energy consumption, ranking first in the country's energy consumption ratio. For this reason, the country has formulated the basic principle of "conserving energy and realizing sustainable development". [0003] According to experts, compared with other building energy-saving technologies, external wall insul...
