Problems solved by technology

Since the middle part of this type of hollow wall brick is empty, it is easy to loosen when it is nailed into the wall to hang heavy objects. For this reason, the Chinese invention patent "A Fireproof Foam Brick and Its Production Method", application number: CN201310593359, A formula for fireproof foam bricks is disclosed. The raw materials used in the formula are complex, and the formula contains fine stone chips. Since the particles of the stone chips are relatively coarse, it is easy to pierce the bubbles produced by the foaming agent, causing the raw materials to condense together, which is not ideal. At the same time, this formula has no material to stabilize the air bubbles, and it is easy to cause the air bubbles to burst, which can cause the air bubbles to communicate with each other, failing to achieve the predetermined effect of heat preservation and fire prevention

Abstract

The invention provides a self-thermal insulation fireproof building block formula, and belongs to the field of building materials. The building block is composed of the following raw materials in percentage by weight: 40 to 45.5% of cement, 11.4 to 17% of mineral powder, 11.4 to 17% of river sand, 26% of water, 2.3 to 2.6% of a foaming agent water solution with a concentration of 10%, and 0.13% of a foam stabilizing agent water solution with a concentration of 10%. The building block is prepared by the following steps: mixing the raw materials together, stirring, foaming, moulding, cutting, drying by wind, and curing so as to obtain the finished product. A foaming stabilizing agent is added, so the generated bubbles will not be broken easily during the production process and are evenly distributed in the moulded building blocks, and thus a better heat insulation and fireproof effect will be achieved.

Description

technical field [0001] The invention relates to the construction industry, in particular to a formula for thermal insulation and fireproof building blocks. Background technique [0002] At present, the insulation bricks on the market are mainly hollow fired mud bricks made of clay or unfired cement bricks whose formula raw materials are mainly made of cement, sand, and limestone particles. Since the middle part of this type of hollow wall brick is empty, it is easy to loosen when it is nailed into the wall to hang heavy objects. For this reason, the Chinese invention patent "A Fireproof Foam Brick and Its Production Method", application number: CN201310593359, A formula for fireproof foam bricks is disclosed. The raw materials used in the formula are complex, and the formula contains fine stone chips. Since the particles of the stone chips are relatively coarse, it is easy to pierce the bubbles produced by the foaming agent, causing the raw materials to condense together, wh...
