Description
Technical field
The present invention relates to wood producing technical field, in particular to a kind of high-strength anti-corrosion wood-plastic composite flitch
Material and preparation method thereof.
Background technology
Wood plastic composite, is with resins such as polyethylene or to reclaim waste or used plastics and the natural biological such as wood powder, powder of straw fibre
Dimension is composited, and has the double grading of timber and plastics, has fully demonstrated a series of advanced reason such as the utilization of resources, environmental protection and saving
Read, be preferable Green Product.It is applied widely, also solves plastics, wood industry waste resource more simultaneously
Raw Utilizing question.Though but so, Wood plastic composite initial stage of development, the ratio of Plant fiber is relatively low, the general ＜ of content 50%,
Plastics macromolecule base material is main component, improves wood and moulds fungus-proof antisepsis ability, is the most once thinking that moulding woody body had resistance to
Rotten performance.But the later stage increases along with the improvement of technology, the ratio of Plant fiber, content is even up to 70%, due to plant
Containing half sugar, hemicellulose, cellulose in fiber, even possibly together with the nutrient substance such as starch and albumen so that wood-plastic composite
Material is more susceptible to corruption.So, tradition Wood plastic composite is modified, improves its intensity and anti-corrosive properties are the most necessary.
Summary of the invention
It is desirable to provide a kind of high-strength anti-corrosion wood plastic composite board, this wood plastic composite board has excellent
Different intensity and anti-corrosive properties.
To achieve these goals, the invention provides a kind of high-strength anti-corrosion wood plastic composite board, by following heavy
The raw material of amount part is made: polystyrene 30-50, Plant fiber 20-40, ACR5-10, wood powder 30, wollastonite 6-10, peroxidating two
Isopropylbenzene 1.2-1.8, stearic acid 0.2-0.6, calcium carbonate 6-10.
Present invention also offers the manufacture method of a kind of high-strength anti-corrosion wood plastic composite board, comprise the steps of
(1), each raw material is weighed by formula ratio；
(2), polystyrene, Plant fiber, ACR, wollastonite, cumyl peroxide, stearic acid, calcium carbonate are placed in machine
Stirring 3-6 minute in tool stirred tank, mixing；Extruder is used to carry out melt blending pelletize, extruder barrel temperature 140 DEG C-
180 DEG C, die head temperature 150 DEG C-190 DEG C, obtain modified plastics particle；
(3) stir 6-8 minute in, by modified plastics particle, wood powder being placed in mechanical stirring kettle, mixing；
Extruder is used to carry out melt blending extrusion molding, extruder barrel temperature 160 DEG C-190 DEG C, die head temperature
155 DEG C-175 DEG C, i.e. make.
By technique scheme, the present invention by individual composition is stirred, after melt process, obtain to mould wood compound
Material sheet material has high intensity and anti-corrosive properties, and preparation method is simple, and raw material is easy to get.
A kind of high-strength anti-corrosion wood plastic composite board of the present invention, it is convenient to manufacture, traditional plastics-production work
Skill i.e. can be used for its production and processing and fabricating without improving, and production cost is low；Comparing with common plastics sheet material, amount of plastic used subtracts
Little, rigidity is bigger, more resistant to creep, it is not easy to deform, the industrial or agricultural leftover pieces such as wood powder can be carried out twice laid simultaneously,
Reduce products material cost；Comparing with common wood sheet material, timber usage amount is few, can reduce the cutting capacity of timber, will not be as wood
Material sheet material is the most easy to crack, damage by worms, buckling deformation etc., it is not necessary to carry out preservative treatment；Compare with other wood plastic composite board,
Having the features such as intensity height, ultraviolet resistance and higher, colour-fast, the without putrefaction of oxygen degree of aging, service life is longer.
