Embodiment 1

[0012] Example 1, grind 50 parts of coal gangue, 20 parts of gypsum, and 1 part of lime for 30 minutes; grind 5 parts of nano-silica and 4 parts of zirconia for 20 minutes; add the ground coal gangue, gypsum, Lime, nano-silica, and nano-zirconia are fully stirred for 20 minutes to obtain the required infrared reflection negative carbon cement.

Embodiment 2

[0013] Example 2, grind 60 parts of coal gangue, 30 parts of gypsum, and 10 parts of lime for 60 minutes; grind 15 parts of nano-silica and 10 parts of zirconia for 40 minutes; add ground coal gangue, gypsum, Lime, nano-silica, and nano-zirconia are fully stirred for 40 minutes to obtain the required infrared reflection negative carbon cement.

Embodiment 3

[0014] Example 3, 55 parts of coal gangue, 25 parts of gypsum, and 5 parts of lime were ground for 45 minutes; 10 parts of nano-silica and 7 parts of zirconia were ground for 30 minutes; the ground coal gangue, gypsum, Lime, nano-silica, and nano-zirconia are fully stirred for 30 minutes, and the required infrared reflection negative carbon cement is obtained.

[0015] The above-mentioned cement can be used on the outer roof and outer wall of the building to reflect external infrared rays so as to reduce the indoor temperature, and can also be used as a building adhesive.

Abstract

The invention relates to infrared-reflecting negative-carbon cement and a preparation method thereof. The infrared-reflecting negative-carbon cement comprises the following components: by weight, 50-60 parts of coal gangue, 20-30 parts of gypsum, 1-10 parts of lime, 5-15 parts of nano silica, 4-10 parts of nano zirconia and 5-15 parts of a dispersing agent. The preparation method of the infrared-reflecting negative-carbon cement is as follows: grinding the 50-60 parts of coal gangue, 20-30 parts of gypsum and 1-10 parts of lime for 30-60 min; grinding the 5-15 parts of nano silica and the 4-10 parts of nano zirconia for 20-40 min; adding the ground coal gangue, gypsum, lime, nano silica and nano zirconia into a mixing container, fully stirring for 20-40 min to obtain the needed infrared-reflecting negative-carbon cement. The infrared-reflecting negative-carbon cement can effectively isolate infrared irradiation to reduce building energy consumption and reduce carbon emissions, and can absorb carbon dioxide in use processes.

Description

technical field [0001] The invention relates to a cement and a preparation method thereof, in particular to an infrared reflection negative carbon cement and a preparation method thereof. Background technique [0002] Sunlight is mainly composed of infrared rays, visible light and ultraviolet rays. In the contained energy, infrared rays accounted for roughly 45% of the total, visible light accounted for 45%, and ultraviolet rays accounted for 5%. Visible light itself has less heat, and the heat that people feel mainly comes from the accompanying infrared radiation. [0003] Therefore, if there is a material that can reflect infrared and visible light in the sun in a targeted and selective manner, it can reduce the indoor temperature in summer, thereby significantly saving many countries and regions from using air conditioners to cool down in summer. huge energy consumption. Another "beneficial to the city as a whole" effect is to reduce the "heat island effect" of large a...
