Problems solved by technology

These technologies use ceramic waste slag, cement, etc. as raw materials. Ceramic brick polishing mud and fluorogypsum have not been used in the above materials. In the above patents, no air-entraining and hydrophobic components have been introduced to affect the thickening rate and density of the insulation material after pouring. The initiation rate is regulated, and after the insulation material is prepared, the internal pores are macroscopic pores, and there are fewer microscopic pores. When the density of the insulation material drops to 300kg / m 3 Below, due to the low strength of the space wall, the damage rate is low during production and construction, which cannot meet the needs of industrial production

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a ceramic tile polishing mud and a diatomite-based microporous thermal insulation material and a preparation method thereof. Background technique [0002] With the improvement of people's living comfort, energy consumption is gradually increasing. Building energy consumption has accounted for 35% of the total energy consumption of the society. Reducing building energy consumption is of great significance for energy conservation, especially in cold and severe cold areas. After the energy-saving standards of 75% for residential buildings and 65% for public buildings, higher requirements are put forward for the energy-saving effect of building envelopes. Thermal insulation materials play an important role in building energy conservation. Traditional organic thermal insulation materials have good thermal insulation effects and low thermal conductivity, and can ...
