Method for preparation of composite hollow tile for ornamenting

Abstract

The invention comprises the following steps: (1) Stirring cement, stone dust, rock ballast and water to form base stock according to a certain weight proportion. (2) Putting the base stock in the lower mould frame of a mould, and prepressing the base stock in a hydraulic pressure moulding machine to form a base stock layer. (3) Stirring the solution mixed by cement, silver sand, colourful paint, water repellent and water according to a certain weight proportion to form a colourful material. (4) Filling the colourful material in the lower mould frame of the base stock layer, and pressing the colourful material with the hydraulic pressure moulding machine to form colourful decorated basso-relievo bricks. (5) Ejecting the basso-relievo bricks from the mould frame waiting to be used. (6) Stirring stone dust, rock ballast, cement and water separately according to a certain weight proportion to form a mixed material. (7) Pouring the mixed material in an air brick mould, shaking and pressing the mixed material to form a certain form. (8) Dipping the basso-relievo bricks in water and then taking out, putting the basso-relievo bricks on the air bricks, knocking and pressing the basso-relievo bricks, the grout flows in the flutes on the back of the basso-relievo bricks to make the basso-relievo bricks combine with the air bricks firmly. (9) Disassembling the mould, watering and maintaining the bricks after the bricks solidified.

Description

technical field [0001] The invention relates to a method for manufacturing building materials, in particular to a method for manufacturing composite decorative hollow bricks. Background technique [0002] There are many high-rise buildings in the city, and most of the hollow bricks used are simply built, and their compressive and seismic performances are relatively poor. At the same time, with the continuous development of economic construction, the problem that the veneer bricks or stone plates used in the exterior wall decoration of buildings are easy to fall off has increasingly become the focus of complaints about the quality of construction projects. In particular, the exterior walls of some large-volume and wide-ranging residential projects are still quite serious. Due to the different materials of the existing hollow bricks and veneer bricks or stone slabs, and inconsistent shrinkage rates, leakage is prone to occur after a heavy rain, and the inner side of the exteri...

AI Technical Summary

Problems solved by technology

It can be seen that in addition to the poor compressive and seismic performance of the existing hollow bricks, the veneer bricks or stone plates used for exterior wall decoration also have safety hazards that are easy to fall off, single color, and high decoration engineering costs.
