Description
Technical field
The present invention relates to integrated wall plate technical field more particularly to a kind of straw fiber boards.
Background technique
Fiberboard, which refers to be interweaved lignocellulose fiber, to be formed and utilizes wood-based plate made of its intrinsic glueability.It is fine
Dimension plate has many advantages, such as that uniform in material, intensity difference is not small, easy to crack in length and breadth, widely used.
Existing fiberboard is all made of bamboo fibre and wood-fibred is made, and the material utilized is that timber and bamboo wood produce
Raw, with social development, the supply of the great attention of Environmental, timber and bamboo wood is persistently reduced, so that fiberboard
Cost cannot reduce.
China is large agricultural country, there is a large amount of crop straw refuse every year, due to the recycling effect to stalk
Rate is low, causes a large amount of stalk that cannot be recycled, and is simply incinerated, and crop straw burning refers to agricultural crop straw fire
Burn a kind of behavior to destroy；Crop straw burning causes haze weather, and generates a large amount of poisonous and harmful substances, to people and other lifes
Object health, which is formed, to threaten；And crop straw burning, the combustibles for surrounding of easily igniting often are difficult to control once causing wheatland high fire
System, causes economic loss.Especially near mountain forest, consequence is even more hardly imaginable；Crop straw burning also destroys soil texture, causes
Farm land quality decline, crop straw burning also enter three points of ground, and the microorganism in earth's surface is scorched to death, and humus, organic matter are mineralized, field
Crop straw burning destroys the balance of this set biosystem, changes the physical behavior of soil, has aggravated soil hardening, destroys ground
Power, exacerbates arid, and the growth of crops is thus affected.Forbid burning crops for this purpose, the Chinese government all orders
Burning processing, promotion are recycled agricultural crop straw.
Summary of the invention
Present invention aim to address above-mentioned deficiencies, provide a kind of straw fiber board.
A kind of straw fiber board provided by the invention, it is characterised in that including following parts by weight of component: polyvinyl resin powder
50-60 parts, 30-35 parts of polyvinyl chloride resin powder, 20-22 parts of straw powder, 5-10 parts of calcium powder, ACR be 7-11 parts, Ca Zn composite it is steady

Further, a kind of production method of straw fiber board, as follows:
Step 1, the stalk of recycling will be crushed by stalk crasher, the fragment size of crushing is 1-3mm；
Step 2, straw powder is cleaned 4-5 times with clear water；Then straw powder is put into 30%NaOH aqueous solution and is impregnated 20 minutes,
Soaking solution temperature is 90-95 °C；Then straw powder is filtered and is dried；
Step 3, dry straw powder and polyvinyl resin powder, polyvinyl chloride resin powder, straw powder, calcium powder, ACR, calcium zinc are answered
Close stabilizer, polyethylene wax, stearic acid, paraffin, magnesia, magnesium chloride, Lauxite are mixed according to the ratio, when mixing, uses
50-60 rpms stirs at low speed 10 minutes, and mixed slurry is made；
Step 4, mixed slurry is added in high temperature and pressure generator, imports extrusion equipment and carries out extrusion forming；The plate of formation
Cooling and shaping is carried out by the distilled water of low temperature；Sizing plate smooth standing 4-5 days；Straw fiber board is made.
A kind of straw fiber board provided by the invention, using straw refuse as raw material, and by modified so that with tree
Rouge plastics more preferably can be merged mutually, make full use of stalk, and reach the intensity of existing bamboo and woods fiber plate；Realization has straw powder
High efficiente callback utilizes, and solves contamination hazard of the existing processing mode of agricultural crop straw to environment.
