Preparation method of hollow self-insulation building block

Abstract

The invention discloses a preparation method of a hollow self-insulation building block, belonging to the fields of waste utilization and preparation of inorganic non-metallic materials. According tothe invention, cement is used as a main raw material, and straw fibers and fly ash are used as modification admixtures; the prepared hollow self-insulation building block is low in heat conductivity coefficient and good in insulation effect; low-carbon reutilization of straw is realized, and regional climate, environmental adaptability and energy efficiency of a building are improved; and the straw fibers are loose and low in heat conductivity coefficient, and the straw fibers are recycled to serve as a modification material and added into a fly ash building block, so the problems of environmental pollution and resource wasting caused by burning of straw outdoors can be solved, the use amount of cement can be reduced, the porosity of the building block is improved, and the density and theheat conductivity coefficient of the building block are reduced.

Description

technical field [0001] The invention relates to the fields of waste utilization and preparation of inorganic non-metallic materials, in particular to a method for preparing hollow self-insulating blocks. Background technique [0002] The use of polystyrene and other materials as external wall insulation materials is prone to fires, and the exterior finishes often fall off, which not only affects the appearance, but may even cause heavy casualties. Therefore, many provinces and cities have restricted the use of external wall insulation. In addition, when materials such as polystyrene are used to construct the thermal insulation system in the wall, the usable area of ​​the room is occupied. Therefore, the self-insulation system of the envelope structure has become the focus of research, especially in hot summer and cold winter regions. Contents of the invention [0003] In order to solve the above problems, the present invention uses cement as the main raw material, and use...
