Description

technical field

[0001] The invention relates to the field of building wallboards, in particular to a stone-plastic partition wall composite board and a preparation method thereof. Background technique

[0002] At present, the traditional red brick is still used as the main wall structure in the construction industry, but due to policy reasons, the red brick will withdraw from the construction market. Therefore, new wall material technologies continue to emerge to meet the new needs of the construction market. At present, in addition to clay bricks, there are also industrial waste slag block bricks, silicate and sulphoaluminate cement wallboards, etc. for building wall materials. The traditional clay solid brick, because of its serious waste of land resources, serious energy consumption, and serious pollution of the environment, at the same time, the construction project is not energy-saving, the construction labor intensity is high, the construction cost is high, the speed i...
