A kind of granular hollow building material and its preparation method

Abstract

The invention relates to the technical field of building base materials, in particular to a granular hollow building material and a preparation method thereof. At present, wall blocks applied in later secondary structural construction in building industry mostly are building materials such as ceramsite bricks and aerated concrete blocks, and the light building materials have respective defects. According to the hollow building material, a hollow hard shell is composed of an inner shell body and an outer shell body; the inner shell body is composed of a single base layer; the outer shell body is formed by alternatively arranging a reinforcing layer and a solidification layer and wraps the exterior of the base layer; the inner surface layer of the outer shell body is the reinforcing layer, and the outer surface layer of the outer shell body is the solidification layer. Through the characteristics of super absorbent resin, the base layer inner shell body is made and alternatively coated with the reinforcing layer and the solidification layer. The hollow building material has the advantages of being small in weight, capable of insulating sound and thermal and resisting dampness and fire and the like, the preparation technology is simple, the production cost is low, high-temperature calcination is not needed in the preparing and producing process, and energy conversation and environment protection are achieved.

Description

technical field [0001] The invention relates to the technical field of building basic materials, in particular to a granular hollow building material and a preparation method thereof. Background technique [0002] At present, the construction industry advocates green and environmentally friendly building materials. Most of the wall blocks used in the secondary structure construction in the later stage are building materials such as ceramsite bricks, aerated concrete blocks, and gypsum blocks. These building materials have their own characteristics and their own shortcomings. . Ceramsite bricks and aerated concrete blocks are lightweight building materials, which have the advantages of light weight, sound insulation and heat insulation, which greatly reduce the weight of building materials, but the price of ceramsite materials is relatively high, and the raw materials for ceramsite production are industrial slag crushing After mixing sand, gravel, cement, uniform mixing and ...

AI Technical Summary

Problems solved by technology

Ceramsite bricks and aerated concrete blocks are lightweight building materials, which have the advantages of light weight, sound insulation and heat insulation, which greatly reduce the weight of building materials, but the price of ceramsite materials is relatively high, and the raw materials for ceramsite production are industrial slag crushing After mixing sand, gravel, cement, uniform mixing and pressing to form, the production process is complicated, the loss is large, the surface of the ceramsite brick is uneven, the wall after the wall is built, the wall needs to be plastered, the cement mortar is used in a large amount, and the economy is poor; The production process of aerated concrete blocks is complicated, the investment in equipment is large, and the production cost is high

Gypsum block is an internationally recognized green building material product, safe and environmentally friendly, but its production cost is high, its weight is large, and its strength is low, so it is generally used for interior walls
