1.0g/cm3When, need board using poplar board two to open, automobile interior decoration wood-plastic board leftover pieces are 6.4kg/m2~7.7kg/m2, coupling agent (titanium
Sour four butyl esters) it is 0.20g ~ 0.38g, dispersing agent (ethyl alcohol) is 1.20g ~ 2.28g；
(2) it is suppressed using pressure sintering, selects flawless board using poplar board, be placed in constant temperature oven dry 2 h, then weigh
The coupling agent of 0.20g ~ 0.38g mixes coupling agent and dispersing agent according to 1:6 ratio, uniformly brushes on board using poplar board surface, in
It is spare that 2 h are spontaneously dried under room temperature environment；Automobile interior decoration leftover pieces (abbreviation sandwich layer particle) are crushed, do not add any add
Add agent and to be placed in 24 h of natural drying at room temperature spare；Mold is placed on a board using poplar board, board using poplar board is as plate
Back side facing material uniformly mats formation sandwich layer particle in the cavity plate of mold, by the punch-pin of mold that the sandwich layer in cavity plate is broken
Material compacting, compacting move back punch-pin and cavity plate except mold, put a board using poplar board on the sandwich layer particle surface paved, then will
The composite board paved is put into vulcanizing press, and the finger gauge of 8mm is put in composite board two sides, carries out precompressed, precompressed pressure
Power is 0.1 MPa, 1 min of time；It is then placed in another vulcanizing press and carries out hot pressing, hot pressing temperature is 190 DEG C ~ 210
DEG C, hot pressing pressure is 2Mpa ~ 6Mpa, hot pressing time 5min ~ 9min, sandwich layer particle density 0.8g/cm after compacting3~1.0g/cm3；
Slab is transferred in vulcanizing press used in precompressed after release and is cooled down, pressure be 0.1 MPa, the time be 6 min ~
8min carries out mechanics properties testing after being cut into test specimen by requirements of the national standard.
The positive effect of the present invention is that its equipment is simple；There is no complicated technologies, technique, utilize the existing production of wood-based plate
Technology can be manufactured；Required clad can board using poplar board is the current domestic most common veneer type, and supply is abundant, required each
Class chemical reagent has sale on the market, belongs to common chemical reagent；This plate contains wood fibre, has identical with timber
Processing performance, manufacturing process are simple；Clad can board using poplar board its surface after being ground is relatively smooth, is conducive to process.This plate
Material Checking of static bending intensity value is about 4 times of set quota value；Elasticity modulus is about 3 times of specified value；Band bonding strength and rule
Definite value is close；Rift grain bonding strength is about 3 times of specified value；Thickness swelling rate is about the half of specified value.The present invention is not
Only raw material sources are extensive, at low cost, simple production process, and good effect is that properties of product are excellent.
Composite board, for four factors, is L with sandwich layer particle density after hot pressing temperature, hot pressing pressure, hot pressing time, compacting
(34) after orthogonal test, and obtained with range method analysis: when hot pressing temperature is 210 DEG C, hot pressing time 9min, hot pressing pressure is
3MPa, sandwich layer particle density is 0.9g/cm after compacting3When, clad can fibrilia/polypropylene composite board good mechanical properties, property
The Some Mechanical Properties testing result of energy preferably plate is as shown in table 1.
