Abstract
The invention discloses production equipments and its technique that a kind of two-component hot melt adhesive pastes package compound film, and the equipment includes two-component glue feeder, apparatus for coating, compounding machine, bondline thickness detection device and PLC control device；The technique realizes coating weight closed-loop control by PLC control device and bondline thickness detection device, is coated on two-component hot melt adhesive continuously accurately on wide cut coiled material, so that production process is more efficient, more environmentally-friendly, more energy saving.Cooled down in process of production by chill roll to the composite membrane after fitting, two-component hot melt adhesive is made to be quickly cooled to solid-state, so that fast implementing the no-solvent polyurethane glue of two-component has initial bonding strength, improved reliability, avoid bulk waste product.
Description
Technical field
The present invention relates to be related to composite membrane production field, and in particular to the life of two-component hot melt adhesive stickup package compound film
Produce equipment and its technique.
Background technique
Currently, product of the composite membrane as Flexible-Packaging Industry, general production technology are as follows: using glue by two layers of plastic film
(or aluminium foil, paper) is combined into an integral membrane.
Flexible-Packaging Industry is mainly produced to enterprises such as shelf stable prepared foods, drug, chemical product, cosmetics, pesticide, seeds and is provided
Color printing plastic compound bag, composite membrane, these complex pockets (film) are to pass through glue by the plastic foil, paper, metal foil of two or more layers
Water (adhesive) bonding is combined.It is bonded compound technique in current domestic and international market all mainly using 1) solvent type
Glue dry type is compound；2) water-base cement dry type is compound；3) compound 4) the solvent-free compound equal four big classifications of extrusion.
Solvent type glue dry type is compound main using two-component solvent borne polyurethane glue, since easy to operate and performance stabilization can
By the characteristics of, be at present it is most widely used.But the organic solvent due to glue itself containing 25-50% or so was using
It also needs additionally to add organic solvent again in journey to be diluted and prepare, one gram of dry glue of every coating just needs about three grams organic molten
Agent, therefore there are environmental pollutions big, unfavorable to operator's health, inflammable and explosive drawbacks such as dangerous, and due to needing to add
Increasing amount organic solvent dilutes, the technique dried again after coating, for using for producer there is also at high cost, energy consumption is high,
Easily there is the problems such as dissolvent residual is exceeded in product.
Water-base cement dry type is compound main using water soluble acrylic acid esters glue, has preferable initial bonding strength, does not also need organic
Solvent participates in use process, but uses the properties of product of this kind of glue fitting limited, and non-refractory, not resistant to water, intensity are less
Height is only adapted to the compound of some light packaging structures (such as packaging film of biscuit, instant noodles).Due to needed before compound by
Drying adhesive, therefore it is also very high to use water-base cement to carry out the compound energy consumption of dry type.
Squeeze out that compound directly lower, mobility is preferable resin extruded at film and other are thin by polyethylene (PE) class fusing point
Film is compound, but is only used for the compound of hot sealing layer, and requirement great talent has an economic benefit, therefore application range and occupation rate of market relatively have
Limit.
Solvent-free combination process generallys use the no-solvent polyurethane glue of two-component (or one-component), solves three of the above
The problem of complex method, has the advantages such as environmental protection, efficient, low cost, is current Flexible-Packaging Industry just in one kind of rapid rising
Combination process.But this kind of two-component glue due to after mixing generally in all still liquid within (0.5-4 hour) for quite a long time
State needs dedicated coating equipment complex, to the tension force precision of equipment so not having initial bonding strength (initial bond strenght)
It is required with the operation level of personnel very high.When for compound thin-film material be inside be printed with light color inks (as white or
Yellow) PET (polyethylene terephthalate) film and aluminium foil or PET aluminizer when, since the glue after mixing exists
For quite a long time within (0.5-4 hours) all or liquid, so glue can be between double-layer films because of the change of temperature, pressure
Change and occur and shrink and microfluidic, cause glue uneven on each localized micro of composite membrane, by aluminium coated or aluminium foil
Reflection, seems from PET film side, the different spot of light and shade is had at light color inks.This problem of appearance leads to existing market
On no-solvent polyurethane glue be not used to the compound of PET and aluminium foil, PET and aluminum plated PET, and this kind of composite construction is wide
It is general to be applied to the food more demanding to barrier property and pharmaceutical packing, therefore comparatively this class formation can only use not ring at present
It protects and the solvent type glue dry type of higher cost is compound.In addition, in porous fibre structures such as composite paper, non-woven fabrics, by
It is in the lower flow regime of viscosity for a long time in solvent-free glue, can be absorbed into internal structure by fibre structure, cause to glue
The place's of connecing glue is very few and then bonding is caused to fail.
Summary of the invention
Present invention seek to address that above-mentioned technical problem, a kind of two-component hot melt adhesive is provided thus and pastes package compound film
Production equipment and its technique make no-solvent polyurethane glue have initial bonding strength in recombination process, while meeting solvent-free compound use
In the PET performance requirement compound with aluminium foil, PET and aluminum plated PET.
The present invention be solve its technical problem the technical solution adopted is that:
A kind of two-component hot melt adhesive pastes package compound membrane production equipment, including two-component glue feeder, apparatus for coating,
Compounding machine, bondline thickness detection device and PLC control device；Two-component glue feeder is mounted on including two adhesive disolving tanks, correspondence
Two metering pumps of two adhesive disolving tank outputs, and it is correspondingly connected with two utilidors of two metering pump output terminals, institute
Two metering pumps are stated to be connected with PLC control device respectively；Apparatus for coating includes shifting steel rider, the transfer on rear side of transfer steel rider
Rubber roller, the coating steel rider on rear side of transfer rubber roller, the gluing pressure roller above coating steel rider, the transfer steel rider, transfer
