Abstract

The invention relates to thermal insulation mortar prepared from waste tiles and a preparation method of the thermal insulation mortar, which belong to the field of building materials. The thermal insulation mortar is prepared from, by weight, 400-500 parts of cementing materials, 100-280 parts of quartz sand, 200-400 parts of modified waste tile particles, 7-10 parts of cellulose, 2-5 parts of water reducing agents and 2-4 parts of tackifiers; and the particle size of the modified waste tiles is 0.5-2 mm, and the accumulation area is 70-90 kg/m<3>. Vitrified waste tile aggregate and quartz sand are taken as aggregate, and Portland cement or aluminate cement is taken as a cementing material, so that resource utilization of waste tiles can be realized, and the problems of environmental pollution, resource and energy consumption and the like caused by the waste tiles can be reduced to the greatest extent; waste tiles are crushed and processed to prepare waste tile particles, through acidification, vitrification and modification, the specific surface area and porosity of the waste tile particles are increased, and the water absorption rate and the heat conductivity coefficient of the waste tile particles are reduced, so that the heat conductivity of the waste tile particles is reduced, and the heat preservation performance of the mortar is effectively improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a thermal insulation mortar prepared from waste bricks and tiles and a preparation method thereof. Background technique [0002] Building energy consumption usually refers to the energy consumption of civil buildings during use, mainly including the energy consumption of heating, ventilation, air conditioning, lighting, water supply and drainage, elevators and other aspects of the building. As one of the largest energy consumers in the world, buildings consume more than a quarter of the world's total energy consumption and release greenhouse gases into the air. Building energy is one of the largest energy consumers, and it is an energy-using field with the greatest energy-saving potential. Therefore, building energy conservation is the focus of energy conservation work. In the current building energy-saving means, thermal insulation mortar is often used as building...
