Refractory brick with heat preservation efficiency and processing technology

Abstract

The invention discloses a refractory brick with thermal insulation efficiency and a processing technology, and relates to the technical field of refractory bricks. The refractory brick comprises a main base material, a thermal insulation base material, a binding agent and an auxiliary material, wherein the content ratio of the main base material to the thermal insulation base material to the binding agent to the auxiliary material is 4: 2: 3: 1. According to the refractory brick with the heat preservation efficiency and the processing technology, heat preservation materials such as the expanded perlite, the aluminum silicate fibers and the kieselguhr are added into the raw materials of the refractory brick, and heat insulation and fire prevention materials such as the foam glass, the glass cotton and the polyurethane are also added into the raw materials of the refractory brick, so that the heat preservation and fire prevention performance of the refractory brick is fully guaranteed, the thermal insulation performance of the refractory brick can be effectively guaranteed, the quality of the refractory brick can be directly improved, and the service life of the refractory brick is prolonged. Finally, the HN-605 glue and the high-temperature binding agent are added into the refractory brick, so that the structural fastness of the refractory brick is greatly guaranteed, and the product quality of the refractory brick is improved.

Description

technical field [0001] The invention relates to the technical field of refractory bricks, in particular to a refractory brick with thermal insulation performance and a processing technique. Background technique [0002] Silica heat-insulating refractory bricks refer to heat-insulating refractory products made of silica as the main raw material, and the SiO2 content is not less than 91%. Due to the characteristics of the brick, the load softening starts at a high temperature, and the volume expands slightly during the heating process, which enhances the integrity of the kiln. [0003] Silica heat-insulating refractory bricks are a kind of refractory bricks. In the modern construction industry, refractory bricks are more and more widely used, and their role is becoming more and more important. [0004] While the existing refractory bricks are pursuing thermal insulation performance, it is difficult to make up for the defects in other performances, such as flame retardancy, st...

Problems solved by technology

[0004] While the existing refractory bricks are pursuing thermal insulation performance, it is difficult to make up for the defects in other performances, such as flame retardancy, structural fastness, etc., which need to be strengthened and need to be improved and compensated in a balanced manner. For this reason, we propose a Refractory brick with thermal insulation performance and its processing technology
