Problems solved by technology

However, the fatal shortcoming of hollow bricks is their poor seismic performance. Of the 25 people who died in the Yingjiang earthquake in Yunnan, 11 died because of the collapse of hollow brick houses.
Although there are more and more researches on improving the compressive performance of hollow bricks, there are still great defects in the actual application process, which needs further improvement.

Abstract

The invention discloses a method for preparing a shale sintered hollow brick from waste plastics, which belongs to the technical field of hollow brick processing and comprises the following steps: (1)pretreating waste plastics; (2) premixing; (3) stirring and aging treatment; (4) preparing a green brick; (5) preparing a finished product. According to the method for preparing the shale sintered hollow brick from the waste plastic, the waste plastic is recycled for preparing the sintered hollow brick, cyclic utilization of resources is achieved, the processing technology is improved, the finally-prepared hollow brick is high in compression resistance, compared with a control group, the method has significance, energy conservation and environmental protection are achieved, and the quality ofthe hollow brick is improved.

Description

technical field [0001] The invention belongs to the technical field of hollow brick processing, and in particular relates to a method for preparing shale sintered hollow bricks by using waste plastics. Background technique [0002] Hollow brick is the main wall material commonly used in the construction industry in recent years. Due to its advantages of light weight and less raw material consumption, it has become the first product recommended by the national construction department. The percentage of the total area of ​​holes in the hollow brick to the area of ​​the brick where it is located is called the porosity of the hollow brick, which should generally be above 15%. Compared with solid bricks, hollow bricks can save a lot of land, soil and fuel for burning bricks, reduce transportation weight; reduce labor intensity during brick making and masonry, speed up construction progress; reduce building weight, increase building layers, and reduce construction costs . But th...
