Present invention also offers the manufacture method of a kind of aging resistance wood plastic composite board, comprise the steps of
(1), render in mixer by the raw material of mass parts, temperature 120 DEG C-160 DEG C；Time is 10-20min, obtains
Mixed material.
(2), mixed material is carried out extruder pelletize, be placed in mould, move into hot press and carry out hot pressing, pressure
For 20-30Mpa, temperature is 140 DEG C-180 DEG C, extrudes blank substrate.
(3), by blank substrate moving into cold press and carry out sizing of colding pressing, temperature is 50 DEG C-80 DEG C, and pressure is 20-25Mpa,
Dwell time is 6-10min, is pressed into and treats finished product,
(4) that, by colding pressing shapes treats that finished product removes from mould, arranges as finished product.
By technique scheme, the present invention by carrying out individual composition mixing, after hot-pressing processing, obtain to mould wood compound
Material sheet material has ageing resistance, and preparation method is simple, and raw material is easy to get.
A kind of aging resistance wood plastic composite board of the present invention, it is convenient to manufacture, traditional plastic production technology without
Need to improve and i.e. can be used for its production and processing and fabricating, production cost is low；Comparing with common plastics sheet material, amount of plastic used reduces,
Deformation is less likely to occur；Comparing with common wood sheet material, timber usage amount is few, can reduce the cutting capacity of timber, will not be as timber
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, tool
Having the feature such as ultraviolet resistance and higher, colour-fast, the without putrefaction of oxygen degree of aging, service life is longer.
