Abstract
It is uneven in order to solve existing distributor dividing technology, especially when single layer CPP film layers are less than 15um or less, it would become hard to evenly distribute, therefore the problem of co-extrusion of multi-layer C PP film layers difficult to realize, the present invention proposes a kind of dispensing arrangement being used to prepare multi-layer C PP films, after using multiple spreader to be shunted, the mode collaborated again, so as to which polypropylene melting liquid is evenly distributed, and the thickness of every layer of CPP film is made to can reach 5um~15um.In this way, the CPP films of original single layer CPP film multilayers can be substituted, while not increasing material cost.
Description
Technical field
The present invention relates to the process equipments of aluminum-plastic composite membrane, are specifically related to multi-layer C PP in production aluminum-plastic composite membrane
The dispensing arrangement of film.
Background technology
Under normal conditions, aluminum-plastic composite membrane constitutes composite material by outer layer nylon layer, intermediate aluminium foil layer and internal layer hot sealing layer,
It is combined between layers by adhesive.But lithium ion battery might have during use corrosive liquid or
Hydrofluoric acid leaks, and the internal layer hot sealing layer of common aluminum-plastic composite membrane is easy to be corroded liquid or hydrofluoric acid infiltration so as to cause short circuit
Phenomenon, the internal layer hot sealing layer of common aluminum-plastic composite membrane is easy to be corroded liquid or the reason of hydrofluoric acid permeates is aluminum-plastic composite membrane
Internal layer hot sealing layer be mainly CPP films, CPP films are a kind of cast polypropylene film, the spy with thermoplastic macromolecule material
Property, during production and processing, since plasticizing completely does not squeeze out either in the process of circulation raw material, some ring of mechanical equipment
Section has that residue is carried under one's arms out either runner dead angle or friction temperature is excessively high that raw material is caused to decompose in advance, just will produce " fish
Eye "；Or part plasticization temperature is excessively high, can also to seem there is glittering white luminous point on film surface, that is, so-called
" fisheye ", and its whole real connection in the place of " flake " or " fisheye " and CPP films is not complete closely sealed, at this position
Relatively weak, then corrosive liquid or hydrofluoric acid are easy to permeate at " flake " or " fisheye ".
In order to solve the problems, such as this, the practice inside industry is the aluminum interlayer layers of foil and internal layer heat in aluminum-plastic composite membrane
It is further added by between sealing between one layer of corrosion-proof layer, corrosion-proof layer and aluminium foil layer and internal layer hot wind layer and passes through adhesive
It is combined.
But if using the way for increasing by one layer of corrosion-proof layer, it can not only increase material cost, that is to say, that more
Increase by one layer of corrosion-resistant coating, additionally, it is preferred that also need to the use of with anticorrosion ability adhesive；Can also it increase simultaneously
Process costs, because increasing by one layer of binder course, it is necessary to it is at least further added by the production line of an application adhesive, it is such
Cost can be relatively high, and production efficiency compare it is relatively low.
In view of this, now it has been proposed that replacing the CPP of single layer thin with the CPP films of multilayer in aluminum-plastic composite membrane industry
Film is the physical characteristic due to CPP itself using the advantage of such way so that it generates the probability of " flake " or " fisheye "
It is relatively small, if hydrofluoric acid or corrosive liquid will be substantially reduced across all CPP film layers using the form of multiple-level stack
Probability.It, will very especially when single layer CPP film layers are less than 15um or less but since current distributor dividing technology is uneven
Difficulty evenly distributes, therefore the co-extrusion of multi-layer C PP film layers difficult to realize.
Invention content
In order to solve problem above, the present invention proposes a kind of dispensing arrangement being used to prepare multi-layer C PP films, can
Polypropylene melting liquid is evenly distributed, and the thickness of every layer of CPP film is made to can reach 5um~15um.In this way, can incite somebody to action
The CPP films of single layer CPP film multilayers originally substitute, while not increasing material cost.
A kind of dispensing arrangement being used to prepare multi-layer C PP films comprising：Material inlet (10), spreader (11,12,
14,15), isocon (111,112,114,115), central tube (113), current limliting cone (13), it is characterised in that：At least two shuntings
Cone (11,12) is set in one heart successively on central tube (113), wherein one end of first spreader (11) and material inlet (10)
It is connected, other one section of first spreader (11) is concentrically nested in one end of second spreader (12), often passes through one point
Flow cone (11,12,14,15), fluid will be divided into it is symmetrical >=2 strands, and by isocon (111,112,114,115) along axis
It is transmitted to direction, being arranged current limliting in the end of central tube (113) bores (13), and will pass through fluid and the front of current limliting cone (13)
Isocon (111,114) meeting and at stream of fluid I, while will pass through current limliting cone (13) fluid and front isocon
(112,115) meeting and the same layer for entering extruder die head by diversion pipe respectively at stream of fluid II, fluid I and fluid II
In.
Further, flow splitter (16) can be individually set on the spreader (11,12,14,15).Flow splitter
(16) spreader (11,12,14,15) can be fixed.
Further, the diameter of the central tube (113) is more than the diameter of isocon (111,112,114,115).
Further, the fluid I and fluid II can row shunts again after spreader (14,15) respectively, and will
Liquid after shunting is transmitted in the same layer of extruder extruder die head.
Further, the PP fluids of melting can be divided by the dispensing arrangement for being used to prepare multi-layer C PP films
2~20 parts；It is more preferred, the PP fluids of melting can be divided into 3~12 parts.
The dispensing arrangement using the present invention for preparing multi-layer C PP films so that the PP raw materials of melting pass through at least two
After spreader (11,12) shunting, and individually with isocon (111,114) meeting and at stream of fluid I, with isocon (112,
115) meeting and at stream of fluid II so that fluid is more stablized, and it is relatively uniform to be formulated distribution, and it is thin can to solve existing CPP
Film is difficult to be made thinner bottleneck, so that Multilayer ultrathin CPP film co-extrusions come true.
