Abstract

The invention discloses a lightweight partition wall board containing lignin. The partition wall board disclosed by the invention is reasonable in material use, and can be used for reducing the dead weight of a construction in a building and saving steel and cement when being used as an interior wall; and because the lightweight partition wall board contains raw materials including lignin and the like, the strength of the partition wall board can be increased, and the seismic grade of the building can be improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a lightweight partition wall board containing lignin. Background technique [0002] Lightweight partition board is a new type of energy-saving wall material, which is simple and convenient in construction, reduces labor intensity, speeds up construction progress, saves the total project cost, and meets the requirements of different customers for the indoor and outdoor environments of modern buildings. Lightweight partition panels are divided into interior walls and exterior walls, and partition panels on interior walls can fully expand the space of the house. However, ordinary magnesia partition boards have disadvantages such as surface moisture absorption and brine return, and high moisture content. Contents of the invention [0003] The object of the present invention is to provide a lightweight partition wall board containing lignin. [0004] The above purpose is achi...
