Specific embodiment
To keep goal of the invention of the invention, technical scheme and beneficial effects more clear, with reference to the accompanying drawing to this
The embodiment of invention is illustrated, it should be noted that in the absence of conflict, in the embodiment and embodiment in the application
Feature can mutual any combination.
Fig. 1 and Fig. 2 is inorfil and wood-plastic composite panel, and composite board includes based on wood moulding frame and inorfil
Filled layer, the outer profile of wood moulding frame can convert according to demand, and wood moulding frame is hollow structure.Fig. 1 is not set reinforcing rib
Composite board schematic diagram, as shown in Figure 1, filled layer 2 is filled in wood moulding frame 1.Fig. 2 is the composite plate for being provided with reinforcing rib
Material schematic diagram separates the space inside wood moulding frame 1 as shown in Fig. 2, being provided with reinforcing rib 101 in wood moulding frame 1,
Filled layer 2 also fills full entire space.
Inorfil and wood-plastic composite panel are by mold coextrusion mold, and mold growth bar shaped, Fig. 3 is mold schematic diagram, such as
Shown in Fig. 3, hollow cavity 301 is provided in mold along its length, the feed end setting of the mold is communicated in described
The discharge end of the wood moulding runner 401 of cavity body, outlet towards the mold of wood moulding runner 401 is arranged.Mold can be squeezed by what is be connected
Mold 4 and shaper 3 assemble out, the two releasable connection, and wood moulding runner 401 is in extrusion die 4, hollow cavity
301 in shaper 3, and extrusion die 4 squeezes out Wood-plastic material, and shaper 3 provides the sky of cooling and shaping for Wood-plastic material
Between.The A-A that Fig. 4 is Fig. 3 is to schematic cross-section, as shown in figure 4, wood moulding runner exit 402 is whole to be linked to be wood moulding frame cross section
Shape, it is ensured that directly extrude the wood moulding frame of constant cross-section, the shape that wood moulding runner exit 402 connects into is according to wood moulding frame
Section determines.The hollow cavity 301 of mold provides the space of cooling and shaping for the parison of the high temperature wood moulding frame just squeezed out.
The preparation method of inorfil and wood-plastic composite panel needs to complete while mold squeezes out wood moulding frame inorganic
The filling of fiber and binder, Fig. 5 is mold production status schematic diagram, as shown in figure 5, needing molten state using extruder
Wood-plastic material is sent in hollow cavity by wood moulding runner, and Wood-plastic material enters hollow cavity in wood moulding runner exit, and pastes
Discharging end motion of the inner wall to mold of hollow cavity, Wood-plastic material be cooled and shaped, formed hollow in hollow cavity
Wood moulding frame 1, and squeezed out from the discharge end of mold；Meanwhile wood of the inorfil even application synchronous with binder in mold
It moulds in frame, inorfil stuff-spraying pipe 5 is also at wood moulding frame out of the feed end of mold extend into mold hollow cavity
Interior, to guarantee to spray enough binders, one or more binder spray guns 6, inorganic fibre is arranged in 5 surrounding of inorfil stuff-spraying pipe
Dimension is delivered to inorfil stuff-spraying pipe 5 by blower, and the synchronous atomization of binder spray gun 6 sprays, and binder is attached to the nothing of ejection
Machine fiber surface, inorfil are blown in wood moulding frame and by binder and wood moulding frame and bond, and wind, which is sent, is conducive to wood
The cooling sizing of frame is moulded, while there is the wood moulding frame of certain temperature to be also beneficial to binder sizing, inorfil filling is full
Wood moulding frame 1 forms filled layer.And then complete the synchronous production of wood moulding frame and filled layer.Inorfil stuff-spraying pipe and bonding
Agent spray gun can change according to the shape and internal structure of wood moulding frame, size, angle and rotation and position, to realize inorfil
It is filled into the every nook and cranny of wood moulding lower portion.After waiting wood moulding frame and filled layer to be all formed, then inorfil and wood are formed
Plastic composite board.Spraying method filling make inorfil by inside binder mutually bonding be integrally formed and inorfil and
Wood moulding frame 1 is also all bonded together.Inorfil and binder are not necessarily to mix the two before spraying, but synchronous spraying two
Person.Inorfil is usually threadiness, and light weight can be conveyed by blower.Inorfil be granulated wool, mineral wool, rock wool,
Alumina silicate fibre or ceramic fibre；Binder be acrylic compounds, organic silicon, starch, epoxy resin, vinyl acetate class,
Silicates or phosphoric acid salt binder；For Wood-plastic material using high molecular material as base stock, wood powder, plastics is added in alternative
The additives such as resin and calcium carbonate.The packed density of filled layer is 30-300Kg/m3。
It is preferred that the Wood-plastic material of molten state is sent into hollow cavity simultaneously by wood moulding runner using extruder, hollow cavity
It can synchronize to penetrate in vivo and be answered with the matched mental section of wood moulding frame outer profile, formation wood moulding frame outer layer embedded with metal profile
Plywood material, composite board increase metal layer, and composite board has more preferably intensity.
When just starting production, and when starting one end of wood moulding frame is just squeezed out from the discharge end of mold, due to wood
Modeling frame is not formed completely, remains to deform, and is preferably mediated the upper and lower part at this end of wood moulding frame, is closed the end seal, so
Inorfil starts spraying filling afterwards, and wood moulding frame ends can prevent outside inorfil blowout wood moulding frame when realizing filling.
Inorfil spraying filling wood moulding of the present invention squeezes out synchronous forming method, and inner inorganic fiber filled layer is because of fiber table
The uniform binder in face solidifies and bonds and be integrally formed, and is integrally formed with the inner surface of the wood moulding frame in outside bonding, whole
Body timber intensity is high, and the interruption that the methods of avoids piecemeal filling rock wool, mineral wool, filled layer caused by discontinuity collapse,
Situations such as accumulation deformation.Inorfil is sent by wind is blown into the cooling and shaping speed that wood moulding lower portion accelerates wood moulding frame,
And the high temperature that the parison of wood moulding frame squeezes out is conducive to the rapid draing solidification of inorfil surface treating adhesive, technique is complementary, energy
Consume it is low, it is high-efficient.Inorfil spraying filling wood moulding squeezes out synchronous forming method, realizes wood moulding frame and inner inorganic fiber
The One-step production of thermal insulation packing layer is processed, and process is enormously simplified, and improves production efficiency, reduces energy consumption, and significantly reduce
Production cost.The present invention can easily pass through the speed of inorfil spraying filling and wind pressure adjustment control as needed
Filled layer density processed, can control the packed density of filled layer is 30-300Kg/m3, meet different requirements.It is filled out in wood moulding frame
The filled layer of inorfil is filled, substantially increases fire-retardant fireproof while guaranteeing basic thermal insulation property for A grades of incombustible materials
Grade.
