Method for manufacturing plant fibre composite wall plate

Abstract

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.

Description

technical field

[0001] The invention belongs to the field of wall materials, in particular to a method for manufacturing a plant fiber composite wall board. Background technique

[0002] At present, in the building structure of our country, the wall materials are still dominated by traditional solid clay bricks. If my country wants to eliminate clay bricks, there must be a large amount (1.0-1.5 billion m 3 ) to replace clay as a raw material for producing new wall materials. At present, light raw materials such as ceramsite, slag, pumice, expanded perlite, and polystyrene foam plastic particles used in the new wall material industry consume a large amount of traditional materials such as bricks, ash, sand, and stone due to their small output and uneven distribution. Due to the high cost of transportation in different places, objectively speaking, the overall situation of light raw materials in my country is insufficient, which has restricted the development of light wall ma...
