Abstract

The invention discloses a wood-plastic building template and a preparation method thereof. The invention uses recycled FRP waste residue and red mud as raw materials and mixes them with PVC and other processing aids to prepare the wood-plastic building template. The wood-plastic building formwork produced by the novel FRP waste slag and red mud of the present invention has good wear resistance, durability, convenience, environmental benefit and social benefit.

Description

technical field [0001] The invention relates to the field of wood-plastic composite materials, in particular to a wood-plastic building template and a preparation method thereof. Background technique [0002] Red mud is the polluting waste that is discharged when the aluminum industry extracts alumina. As the world's fourth largest producer of alumina, China discharges millions of tons of red mud every year. A large amount of red mud cannot be fully and effectively utilized, and can only be stacked in a large area of ​​storage yard, which occupies a large amount of land and causes serious pollution to the environment. Enterprises in our country spend a lot of money every year to deal with red mud, and the treatment of red mud is an extremely important issue. [0003] FRP generally refers to fiber-reinforced thermosetting polymers. FRP has excellent wear resistance, mechanical strength, electrical insulation, chemical stability, and high and low temperature resistance. FRP ...
