Concrete block with plenty of closed tiny bubbles and preparation method of concrete block

Abstract

The invention discloses a concrete block with plenty of closed tiny bubbles. The concrete block comprises a brick and a mould reversing module, wherein a plurality of top holes are formed in the top of the brick; a plurality of edge slots are formed in the top and two sides of the brick; a plurality of side holes are formed in the two sides of the brick; a through hole is formed in one side of the brick; a plurality of transverse perforation holes are formed in the brick; the transverse perforation hole internally consists of a plurality of transverse bubbles; the tail ends of the transverse perforation holes are connected with the side holes; a longitudinal perforation hole is formed on one side of each transverse perforation hole. The concrete block disclosed by the invention has the following beneficial effects: a sodium carbonate reaction raw material is equidistantly added in the transverse perforation holes and the longitudinal perforation holes respectively by use of a transverse perforation hole module and a longitudinal perforation hole module; moreover, sodium carbonate is heated and decomposed into carbon dioxide gas by a high temperature generated by the thermoplastic molding of a thermoplastic molding module, so as to form bubbles in the brick; when the brick is in use, in the case of excessively high temperature, the carbon dioxide gas is discharged from the top holes and the side holes, and a flame-retardant effect is realized.

Description

technical field [0001] The invention relates to the technical field of concrete bricklaying, in particular to a concrete block with a large number of closed fine air cells and a preparation method thereof. Background technique [0002] Concrete block is a new type of building material that is lightweight, porous, nailable, sawable, planable, and has certain earthquake resistance. As early as the early 1930s, my country began to produce this product, and it has been widely used since its development. For the preparation of concrete bricks, the existing concrete blocks are produced by using production molds to shape the production. The produced concrete bricks have the characteristics of uniform specifications, firmness and beauty, and the production rate is relatively high. [0003] However, in the production process of the existing concrete blocks, in order to ensure that the concrete blocks have excellent thermal insulation and fireproof performance at the same time, the p...

Problems solved by technology

[0003] However, in the production process of the existing concrete blocks, in order to ensure that the concrete blocks have excellent thermal insulation and fireproof performance at the same time, the production cost will be increased, and it is difficult for the existing concrete blocks to have thermal insulation and fireproof properties at the same time. , All the characteristics of moisture resistance, it is impossible to ensure that the concrete block has all the above properties and at the same time ensure that the production cost is low, so it is difficult to meet the needs of the general public
