cm3When, it is necessary to board using poplar board two, automotive trim wood-plastic board leftover pieces are 6.4kg/m2~7.7kg/m2, coupling agent（The fourth of metatitanic acid four
Ester）For 0.20g ~ 0.38g, dispersant（Ethanol）For 1.20g ~ 2.28g；
（2）Suppressed using pressure sintering, select flawless board using poplar board, be placed in constant temperature oven and dry 2 h, then weigh
0.20g ~ 0.38g coupling agent, by coupling agent and dispersant according to 1:6 ratios are mixed, uniform to brush on board using poplar board surface, in
2 h are spontaneously dried under room temperature environment standby；By automotive trim leftover pieces（Abbreviation sandwich layer particle）Crushed, added without any
Plus agent and to be placed in the h of natural drying at room temperature 24 standby；Mould is placed on a board using poplar board, board using poplar board is used as sheet material
Back side facing material, uniformly mats formation sandwich layer particle in the cavity plate of mould, by the punch-pin of mould that the sandwich layer in cavity plate is broken
Material compacting, removes the punch-pin and cavity plate of mould, a board using poplar board is put on the sandwich layer particle surface paved after compacting, then will
The composite board paved is put into vulcanizing press, and 8mm finger gauge is put in composite board both sides, carries out precompressed, precompressed pressure
Power is 0.1 MPa, the min of time 1；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 the vulcanizing press used in precompressed after release and cooled down, pressure be 0.1 MPa, the time be 6 min ~
8min, is cut into after test specimen by national standard requirement and carries out mechanics properties testing.
The positive effect of the present invention is that its equipment is simple；In the absence of complicated technology, technique, the existing production of wood-based plate is utilized
Technology can be manufactured；Required clad can board using poplar board is current domestic most common veneer species, and supply is abundant, required each
Class chemical reagent has sale on the market, belongs to common chemical reagent；This sheet material contains wood fibre, with timber identical
Processing characteristics, manufacturing process is simple；Clad can board using poplar board its surface after grinding is relatively smooth, is conducive to processing.This plate
Material Checking of static bending intensity value is about 4 times of set quota value；Modulus of elasticity is about 3 times of setting；Band bonding strength and rule
Definite value is close；Rift grain bonding strength is about 3 times of setting；Thickness swelling rate is about the half of setting.The present invention is not
Only raw material sources are extensive, cost is low, simple production process, and its good effect is that properties of product are excellent.
Composite board is L using sandwich layer particle density after hot pressing temperature, hot pressing pressure, hot pressing time, compacting as four factors
(34) after orthogonal test, and drawn with range method analysis：When hot pressing temperature is 210 DEG C, hot pressing time is 9min, and hot pressing pressure is
Sandwich layer particle density is 0.9g/cm after 3MPa, compacting3When, clad can fibrilia/polypropylene composite board good mechanical properties, property
The Some Mechanical Properties testing result of energy preferably sheet material is as shown in table 1.
