(2), in the upper and lower surface parcel glass fiber material layer of honeycomb core plate；
(3), the honeycomb core plate for wrapping up glass fiber material layer is put into flush coater, to the upper and lower surface even application of glass fiber material layer
Foamed PU material layers, places into matched moulds pressurize in the die cavity of molding die, and then die sinking is taken out, and obtains PHC composites；
(4), injection molding is carried out to be warmed to 50-60 DEG C, obtained PHC composites are put into the die cavity of injection molding；
(5), the die cavity of injection molding is vacuumized, and matched moulds；
(6), using injection device, zero blown polyurethane materials are expelled in mould；
(7), while using the vacuum extractor in injection molding, being adsorbed to zero blown polyurethane materials in injection molding die cavity
Filling, in adsorption process, the laminating upper epidermis in PHC composites of zero blown polyurethane materials forms zero polyurathamc
Protective layer, obtains zero polyurathamc composite；
(8), to zero polyurathamc composite in the die cavity of injection molding pressurize 180-300s, make zero polyurathamc answer
Condensation material curing molding；
(9), molded after the completion of the dwell time, by manually or mechanically hand by zero polyurathamc composite of shaping from injection
Taken out in mould；
(10) zero polyurathamc composite, is put into progress integer deburring in integer edge-neatening apparatus, zero polyurathamc is obtained
Composite finished product；
(11), pack, be put in storage.
A kind of zero polyurathamc composite injection processing method of the present invention, described honeycomb core plate is paper honeycomb
Plate, plastic honeycomb board or aluminum honeycomb panel etc., are used according to actual conditions selection.Described glass fiber material layer is glass woven cloth,
Woven cloth intensity is more preferably, not easy to break.
The invention discloses a kind of injection processing method of zero polyurathamc composite, pass through gathering that this method is processed
Urethane composite, with lightweight, intensity height, the features such as quality is good, product surface is bright and clean, can be used directly, also can be direct
Colouring.Particularly zero polyurathamc protective layer is tightly combined with PHC composites, does not play glue, and service life is long, environmental protection section
Can, it can be widely applied in the industries such as auto industry, the beneficial effect with highly significant.
Brief description of the drawings
Fig. 1 is the zero polyurathamc composite structure schematic diagram of the present invention.
Embodiment
