Environment-friendly building material and preparation method thereof

Abstract

The invention relates to an environment-friendly building material. The environment-friendly building material is prepared from components in parts by weight as follows: 0.5-0.9 parts of sugilite, 0.9-1.5 parts of tsavorite, 14-20 parts of bloodstone, 22-29 parts of red mud, 18-23 parts of cream-colored mud, 12-17 parts of expanded perlite, 9-14 parts of volcanic ash, 3-8 parts of sylvine, 7-12 parts of Shanyin soil and 5-10 parts of clay. The invention further relates to a preparation method of the environment-friendly building material. The preparation method comprises steps as follows: theraw materials in the weight ratio are smashed and mixed uniformly, and a mixture is put in a ball mill for wet ball milling; an obtained product is injected into a die cavity, and a green body is taken out and dried; the green body is fed into a kiln for firing, and the environment-friendly building material is obtained. The building material produced with the formula and the method has the characteristics of high strength, good heat insulation performance and the like, the heat conductivity coefficient is 0.2-0.6 W / m.k, besides, the production technology is simple and easy to operate, and theproduction process has low energy consumption and is more energy-saving and more environmentally friendly.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, to an environment-friendly building material and a preparation method thereof. Background technique [0002] China is a big developing country, but also a big building country. The area of ​​newly built houses is as high as 1.7 to 1.8 billion square meters every year, which exceeds the sum of the built areas of all developed countries every year. With the rapid development of the construction industry, building energy consumption is also increasing rapidly. However, China has a large population, relatively scarce energy resources per capita, extremely serious building energy waste, and the growth rate of building energy consumption far exceeds the possible growth rate of China's energy production. If such high energy-consuming buildings are allowed to continue to develop, the country's Energy production is bound to be difficult to support such wasteful demand in the long run....

However, China has a large population, relatively scarce energy resources per capita, extremely serious building energy waste, and the growth rate of building energy consumption far exceeds the possible growth rate of China's energy production. If such high-energy-consuming buildings are allowed to continue to develop, the country's Energy production is bound to be difficult to support such wasteful demand for a long time
