Energy-saving insulating brick and preparation method thereof

Abstract

The invention discloses an energy-saving insulating brick and a preparation method thereof, and relates to the technical field of insulating bricks. The energy-saving insulating brick comprises the following raw materials in parts by weight: 65 to 75 parts of ordinary Portland cement, 45 to 50 parts of modified fluorgypsum, 30 to 35 parts of fiber toughening particles, 15 to 20 parts of an aluminapowder, 15 to 20 parts of modified diatomite, 10 to 15 parts of cocoamidopropyl betaine, 5 to 10 parts of triethanolamine oleate, 5 to 10 parts of hydroxypropyl guar gum, 5 to 10 parts of nutshells,15 to 20 parts of an addition agent and 65 to 85 parts of water. The energy-saving insulating brick is high in weight, good in insulation effect and high in compressive strength.

Description

technical field [0001] The invention relates to the technical field of thermal insulation bricks, in particular to an energy-saving thermal insulation brick and a preparation method thereof. Background technique [0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environmentally friendly building materials. It is widely used. Usually, the lower insulation brick is made of sawdust, polylight ball, kaolin, bauxite clinker, etc., but the cost of the above-mentioned raw materials is relatively high, and the sintering temperature is high in the process of preparing refractory insulation brick. From Another aspect increases the processing cost. Moreover, the demand for low-density refractory bricks in industrial production is incr...

[0002] With the rapid development of the national economy and the continuous improvement of people's living standards, the consumption of energy is also increasing, and the problem of energy shortage is becoming more and more prominent. Therefore, people pay more and more attention to energy-saving and environmentally friendly building materials. It is widely used. Usually, the lower insulation brick is made of sawdust, polylight ball, kaolin, bauxite clinker, etc., but the cost of the above-mentioned raw materials is relatively high, and the sintering temperature is high in the process of preparing refractory insulation brick. From Another aspect increases the processing cost

Moreover, the demand for low-density refractory bricks in industrial production is increasing, and the requirements for the compressive strength of low-density products are also getting higher and higher. The compressive strength must be above 1.5MPa. However, the low-density refractory bricks currently on the market The above compressive strength cannot be achieved, seriously affecting the reliability and safety of construction projects
