Provided is a process for preparing a
plant fiber composite
wall plate, belonging to
wall material field. The invention resolves the shortages that the
raw material of the existing architectural
wall material is large in consumption, the manufacture cost is high and the distribution of the
raw material is non-uniform. The process steps of the invention are that
crop straw is cleaned and
cut into pieces and is ground by a
fiber re-chipper, and then is dried after dust and big lump material are screened. The prepared
raw material is sent into a glue blend
machine and is added with
adhesive agent of 10-16%. After being uniformly stirred, the raw material and the added
adhesive agent are taken out, added with fire retarding agent and paved, and then are
cut in standard size after being pre-pressed, hot-press-molded and cooled. The plate in standard size is combined with
polystyrene plates via different
layers and thicknesses, the surfaces thereof are stuck with
melamine fireproof plates, and then the
plant fiber composite
wall plate is formed via the combination. The product obtained by the process has the advantages of
low density, light weight, perfect insulation, simple technology, large raw material source, low manufacture cost, waste utilization and environment protection. The invention can be used to produce building separating walls, framed wood structural buildings, mobile movable dwellings, and buildings in tourist spots and the like.
