Description
Technical field：The present invention relates to a kind of vast scale glass fibre-polyurethane Forced Mixing dress for producing superpower polyurethane material
Put.
Background technology：With people to the grasp of polyurethane moulded technology and its reactivity is being controlled to extend its working life
The progress of aspect, polyurethane has been enter into the long-term field of compound material dominated by unsaturated polyester (UP) and vinyl ester resin.Glass
The excellent toughness of enhancing compound polyurethane material is conducive to rear road processing such as to drill, be machined and assembling operation.With tradition
Same with thermosetting compound material is compared, and processed and punching the edge-occurrence of glass fiber reinforced polyurethane composite is few even without micro-
Crackle.Routine glass fiber reinforced polyurethane material has been applied in underbody, storage room bottom plate, protective cover, section bar, big window at present
Frame etc..Further investigation with people to glass fiber reinforced polyurethane, finds the performance of composite with the increase of glass ratio
Its toughness, impact strength, tensile strength and shear strength increase in series again, and this gives people to be applied to prospect to bring infinitely
Imagination space.But, polyurethane compound and the uniform quick continuous mixed problem of vast scale glass of fast reaction are to hinder
Produce the problem of vast scale glass fiber reinforced polyurethane composite industrialization production, such as the increasing presently more than 40% glass ratio
The production of strong compound polyurethane material production heavy tank warehousing bottom plate also rests on artificial hybrid mode, and is poly- in adjustment
Urethane chemical formulation, slowed down reaction speed, is completed in the state of the extension reaction time, and production efficiency is too low.Current scale
The glass ratio of the glass fiber reinforced polyurethane composite of production is usually less than 15%, is usually that glass is passed through into conveying device 13
First mixed with polyurethane polyol component in batch can 14 and pouring nozzle mixing device 16 is injected with being pumped into by measuring pump 15 again
Another component batch can 17 in isocyanates mixing after injection die cavity production, see Fig. 1, when glass ratio is more than 15%, with
The raw material of polyurethane polyol component mixing loses mobility substantially, and measuring pump can not measure conveying, therefore more than 15% glass
It is fine to be produced substantially using the method.The company of Bayer MaterialScience AG of Germany successively have developed several spray up mouldings.
Baypreg methods：This is a kind of battenboard manufacturing process.The cores such as paper honeycomb are embedded between two layers of Chopped Strand Mat, it is poly- with bi-component
Urethane spray immersion, then compression moulding and is heating and curing in Guan Bi mould.Multitec methods：This is the open mold injection skill updated
Art.Mould is injected at room temperature through chopped glass fibre and quick-setting polyurethane compound, and can be consolidated in open mold
Change.Both the above method is also only applicable to less than 40% glass ratio reinforcing material.
The content of the invention：Present invention aim to address more than the 40% vast scale glass fibre-polyurethane that prior art can not be completed
There is provided a kind of a kind of simple in construction, vast scale glass fibre-polyurethane Forced Mixing that can quickly, conveniently, continuously mix for mixed problem
Device, the need for adapting to superpower glass fiber reinforced polyurethane composite industrialization production.
The present invention is using motor 1, transmission device 2, cylindric mixing chamber 3, agitator 4, the top of cylindric mixing chamber
Provided with polyurethane compound inlet 5 and glass inlet 6, there is discharging opening 7 lower end, and motor drives agitator to revolve through transmission device
Turn, cylindrical shape mixing chamber outer wall, which leaves, makes the free running clearance H of agitator contain agitator, it is characterised in that：The agitator
To be evenly distributed with sheet hollow out gear piece 8 on multi-head spiral line on cylindrical cylinder, the spiral roll of Gear Processing is somewhat similarly to
Knife, but hob profile section is trapezoidal, and this tooth section is strip, the effect of hollow out gear piece 8 has three, and one will not be to screw rod
Equally raw material is directly released in the case where not being sufficiently mixed, residence time of the increase raw material in hybrid chamber；Two increases are stirred
Mixing device and raw material contact area makes the agitator rotated at a high speed have more chance impact mixed materials；Three be increase hybrid chamber
Space, can improve the combined amount of unit interval；Revolved above the cylindrical cylinder of hollow out gear piece 8 provided with rotation direction with helix
To identical foliaceous pusher slurry 9, equivalent to one axial flow blower will mix urethane raw and the suction of glass fibre raw material is mixed
Close room.It is to be evenly distributed with sheet hollow out gear piece 8 on three helixes on cylindrical cylinder to test agitator, and at one
Six hollow out gear pieces are evenly arranged with helical pitch L.The pitch angle alpha of helix is between 25 ° to 35 °, preferably 27 °.Hollow out tooth
The flank of tooth 10 of piece and the angle β of cylinder bus are between 25 ° to 40 °, and experiment uses 29 °, along hollow out gear piece side 11 with circle
Element cylinder orthographic projection angle γ is taken between 15 ° to 25 °, and experiment value is 17 °, and design is one in order to reduce stirring resistance, not at this
One component of outer formation send raw material to lower discharge port, is acted on simultaneously with the hollow out gear piece on helix and pusher slurry, convenient continuous
Production.
