[0002] With the intensification of the global energy crisis and the improvement of environmental awareness, the construction industry, as a major energy consumer and carbon emitter, urgently needs to adopt materials to improve building energy efficiency, reduce energy consumption and environmental pollution. In this context, bricklaying sealing materials came into being. They not only have excellent thermal insulation performance, but also can effectively reduce the weight of the building, improve construction efficiency, and meet the requirements of sustainable development.

[0003] The preparation methods of these new materials often involve advanced production processes and technologies, such as using natural lightweight aggregates such as spheroidized sealed pumice aggregates to make multi-row hollow blocks through specific processes to achieve the goal of reducing deadweight and improving thermal insulation and energy-saving performance. At the same time, supporting equipment such as self-insulating block equipment also uses advanced foaming composite technology, which can directly lay foam blocks during the production process without the need for additional fixing tools, greatly improving construction speed and efficiency.

[0004] To sum up, the preparation method of sealing materials for bricklaying and the equipment thereof are a direct reflection of the construction industry's demand for energy conservation and environmental protection, and are also an important way to promote the transformation and upgrading of the building materials industry and achieve sustainable development.
