specific Embodiment approach 1

[0008] Specific Embodiment 1: In this embodiment, the manufacturing method of plant fiber composite wall panels is realized through the following steps: 1. Clean and cut the crop stalks to a length of 3 to 6 cm, crush them with a fiber re-shredder, and sieve out dust and Obtain 40-80 mesh crop straw scraps after bulking; 2. Dry the crop straw scraps at 80-120°C until the moisture content is 3-8%; 3. Add the dried crop straw scraps to In the glue mixing machine, apply an adhesive accounting for 10-16% of the weight of crop straw scraps and stir evenly; 4. Add 1-9% of the weight of crop straw scraps to the glued crop straw scraps. 5. Pre-press the paved slab for 60-150s at room temperature and 4-8MPa; 6. Hot-press at 150-180°C and 6-12MPa 10-17min, then cut the edge after cooling at room temperature; the obtained density is 0.4-0.6cm 3 / g crop straw particle board; Seventh, the crop straw particle board and polystyrene board are layered and compounded, and the surface is pasted...

specific Embodiment approach 2

[0009] Embodiment 2: This embodiment is different from Embodiment 1 in that in step 1, the crop stalk is one of wheat straw, rice straw, corn stalk and cotton firewood or a combination of several of them. Others are the same as in the first embodiment.

[0010] In this embodiment, when the crop straws are a composition, various crop straws can be mixed in any ratio.

specific Embodiment approach 3

[0011] Embodiment 3: This embodiment is different from Embodiment 1 in that in step 2, the crop straw fragments are dried to a moisture content of 4-7%. Others are the same as in the first embodiment.

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...
