Heat insulating brick manufacturing method

Abstract

The invention relates to a method for preparing a heat insulating brick, comprising the following steps: (a) preparing the outer layer of the heat insulating brick: taking the following materials according to the mass ratio, cement, water, sand, asbestos wool or glass fiber wool and brightener, and stirring Pour it into the mold evenly, and air-dry until the surface moisture is slightly dry after vibrating evenly; (b) prepare the raw materials of the heat-insulation brick insulation layer according to the mass ratio, cement, water, foam plastics and foaming agent; take cement and one of them Pour an appropriate amount of water into the mixer and stir into cement slurry, and pour the foaming agent into the rest of the water to stir and foam, then pour into the cement slurry and stir, then pour into the foam and stir evenly; (C) Prepare heat insulation Brick: Pour the heat insulation layer raw material obtained in the above step into the mold filled with the outer layer prepared in step (a), and vibrate the mold until the raw material is flat and compact. The preparation process adopts a semi-automatic technological process, and the operation at room temperature does not require high-temperature firing, the preparation conditions are mild, and the obtained heat-insulating brick has good flatness and gloss.

Description

technical field [0001] The invention relates to a building brick, in particular to a preparation method of a lightweight heat-insulating brick. Background technique [0002] Generally, the top floor of a building is often exposed to the sun. In order to avoid excessive indoor temperature, heat insulating bricks are usually laid on the top floor as heat insulation. [0003] Generally, heat-insulating bricks are prepared manually, or the heat-insulating bricks are prepared at high temperatures, or the proportion of ingredients is unreasonable, so it is not suitable for industrial production. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a method for preparing heat insulating bricks. The proportion of various components of the heat insulating bricks produced by this method is reasonable, the heat insulating effect is good, the weight is light and firm, and the production process is operated at normal temperature. ...
