Abstract
The invention discloses a kind of energy-saving insulating bricks and preparation method thereof, are related to insulating brick technical field, include the raw material of following part meter：65 ~ 85 parts of 65 ~ 75 parts of Portland cement, modified 45 ~ 50 parts of fluorgypsum, 30 ~ 35 parts of fiber reinforced particle, 15 ~ 20 parts of alumina powder, 15 ~ 20 parts of modification infusorial earth, 10 ~ 15 parts of cocamidopropyl betaine, 5 ~ 10 parts of triethanolamine oleate, 5 ~ 10 parts of hydroxypropylguar, 5 ~ 10 parts of shuck, 15 ~ 20 parts of auxiliary agent and water.The present invention is light, heat insulation effect is good and compression strength is high.
Description
Technical Field
The invention relates to the technical field of insulating bricks, in particular to an energy-saving insulating brick and a preparation method thereof.
Background
Along with the rapid development of national economy, the living standard of people is continuously improved, the energy consumption is more and more, and the problem of energy shortage is increasingly outstanding, so that energy-saving and environment-friendly building materials are gradually valued by people, the insulating brick is taken as one of the building materials and is widely applied, the lower insulating brick is usually made of sawdust, poly light balls, kaolin, bauxite chamotte and the like, but the cost of the raw materials is higher, the sintering temperature is higher in the process of preparing the refractory insulating brick, and the processing cost is increased from another aspect. In addition, the demand of industrial production for the low volume weight refractory bricks is increasingly large, the requirement on the compressive strength of low volume weight products is also increasingly high, the compressive strength is required to be more than 1.5MPa, however, the low volume weight refractory bricks in the current market cannot achieve the compressive strength, and the reliability and the safety in the building engineering are seriously influenced.
