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
The invention belongs to the materials for wall field, be specifically related to a kind of manufacture method of string composite wall board.
Background technology
In the building structure of China, materials for wall is still based on traditional solid clay brick at present.China will eliminate clay brick, and a large amount of (10-15 hundred million m will be arranged
3) other resources come instead of clay as the raw material of producing novel wall material.Lightweight materials such as the haydite of new wall material industry use at present, slag, float stone, expanded perlite, polystyrene foam grain, because output is little, skewness, consume traditional materials such as a large amount of bricks, ash, sand, stone, reasons such as strange land cost of transportation height, so objectively the overall condition deficiency of China's lightweight material causes the development of some regional light-weight wall materials to be restricted.
Summary of the invention
The objective of the invention is to have the shortcoming that consumes a large amount of raw material, cost of manufacture height and feed distribution inequality, and a kind of manufacture method of string composite wall board is provided in order to solve the existing building materials for wall.
The method that the present invention makes the string composite wall board realizes as follows: one, agricultural crop straw is cleaned and cuts to long 3～6cm, pulverize with the fiber desintegrator, obtain the agricultural crop straw particle after screening out dust and bulk material; Two, under 80～120 ℃ of conditions, it is 3～8% that the agricultural crop straw particle is dried to moisture content; Three, dried agricultural crop straw particle is added in the glue mixer, apply the adhesive that accounts for agricultural crop straw particle weight 10～16%, stir; Four, add the fire retardant that accounts for agricultural crop straw particle weight 1～9% in the agricultural crop straw particle after applying glue, evenly mat formation into slab then; Five, under room temperature and 4～8MPa condition, with the slab precompressed 60～150s that paves; Six, under 150～180 ℃, 6～12MPa condition, carry out hot pressing 10-17min, then cutting edge again after the cooling at room temperature; Obtaining density is 0.4～0.6cm
3/ g agricultural crop straw flakeboard; Seven, it is compound agricultural crop straw flakeboard and XPS to be carried out layering, and the melamine PLASTIC LAMINATED is pasted on the surface, promptly obtains the string composite wall board.
From resource view, China's agricultural wastes stalk is very abundant.Crops stalk, stem contain abundant filament shape material, belong to Fibrotic material.Fiber quality is light, and every cube of unit weight is generally about 100kg.String is packing material in light weight board, is again toughness reinforcing reinforcing material, and this exactly satisfies light wall board light weight, performance need that intensity is high.With agricultural wastes is raw material, and the straw wall plate of processing energy-saving and environmental protection can replace and remedy a large amount of use other materials on the one hand, and particularly deficient day by day timber resources reduces harvesting of wood amount; On the other hand, can improve the ecological environment, reduce and burn the atmosphere pollution that agricultural crop straw causes, have big economic benefit of tool and social benefit.
It is raw material that method of the present invention adopts agricultural crop straw, through the wood-based plate manufacturing process, utilizes adhesive to carry out hot-press gluing, and applies fire retardant simultaneously, make have good flame-retardance, the materials for wall of sound insulation and heat insulation function.According to the product that above-mentioned process draws, have that density is low, in light weight, good heat preservation performance, technology is simple, the raw material resources amount is big, the characteristics of low cost of manufacture, sharp useless environmental protection.Technical process of the present invention is simple, can make have well fire-retardant, sound insulation, the materials for wall of heat insulation function.Product of the present invention can make full use of the building effective area, alleviate the building own wt, has wide range of applications, and can be used for the building in places such as building partition wall, frame-type timber buildings, movable type prefabricated house room, tourist attraction.
