Description
Technical field
This utility model relates to the double-deck polypropylene composite materials sheet material of a kind of band printing.
Background technology
Polypropylene composite materials sheet material is a kind of sheet material for plastics sucking moulding, and traditional material great majority are that single or multiple lift is total to
Squeeze sheet material, material has polystyrene, polyethylene, polypropylene and a polyester etc., and is essentially all and does not print, final products
Information is also by republishing after molding, or overlaps mark, labeling etc. again and complete, and has that operation is many, speed slow, high in cost of production shortcoming.
Utility model content
The technical problems to be solved in the utility model is just to provide the double-deck polypropylene composite materials sheet material of a kind of band printing, solves
The problem that when existing polypropylene composite materials sheet material makes, operation is many, speed is slow and cost is high.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: the printing of a kind of band
Double-deck polypropylene composite materials sheet material, has the cast polypropylene layer of printing layer, cast polypropylene layer including polypropylene body and top
It is compounded on polypropylene body by double component solvent-free polyurethane adhesive, double component solvent-free polyurethane adhesive and curtain coating
The thickness of polypropylene layer is than for 1:10～1:15, double component solvent-free polyurethane glue on each square metre of interior polypropylene body
The quality of glutinous agent is 2.5～3g.
Preferably, the thickness of cast polypropylene layer is 30～50 μm, can guarantee that the drawing and forming performance of cast polypropylene layer,
Being conducive to printing the printing of layer, when the thickness of cast polypropylene layer is less than 30 μm, printing layer is unfavorable for printing, when curtain coating poly-third
When the thickness of alkene layer is more than 50 μm, drawing and forming poor performance, the shortcoming of using effect difference.
Preferably, the thickness of polypropylene body is 250～400 μm, can guarantee that polypropylene body has good deflection, suction
Molded excellent performance, heat sealability are good, and the barrier property that tool is the best.
In sum, advantage of the present utility model: the 1. cast polypropylene layer that top has printing layer passes through double-component
No-solvent polyurethane adhesive is compounded on polypropylene body, can deflection is good, food safety performance excellence, plastics sucking moulding performance
Excellence, the crystalline p p sheet easily sealing, being provided simultaneously with certain barrier property and cast polypropylene are combined with each other, and can realize
Online molding, fill, sealing, safely and fast, novel form, relative to the technique republished after existing molding, have operation few,
Speed is fast, the advantage of low cost；
2. double component solvent-free polyurethane adhesive is effectively reduced dissolvent residual on polypropylene body, it is ensured that defend
Raw security performance, can be widely used in the packaging of light weight food, daily chemical products and toy etc.；
On the most each square metre of interior polypropylene body the quality settings of double component solvent-free polyurethane adhesive become 2.5～
3g, can strengthen combined strength bination, ensures and is unlikely in outward appearance and forming process to produce the problems such as layering, random distortions, when each flat
When on polypropylene body in side's rice, the quality of double component solvent-free polyurethane adhesive is less than 2.5g, composite effect is poor, easily produces
Layer estranged, when on each square metre of interior double-component polypropylene body, the quality of no-solvent polyurethane adhesive is more than 3g, multiple
Random distortions it is easily generated, the shortcoming that product rejection rate is high during conjunction；
4., by the thickness of double component solvent-free polyurethane adhesive and cast polypropylene layer than for 1:10～1:15, can guarantee that
The effect that cast polypropylene layer is compound, bond properties is high, can be according to the cast polypropylene layer of different-thickness to double component solvent-free
The thickness of adhesive for polyurethane is controlled, and Practical Performance is good, adapts to the demand of different product, can reduce cast polypropylene layer
Come off.
Accompanying drawing explanation
The utility model is described in further detail below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the double-deck polypropylene composite materials sheet material of a kind of band of this utility model printing.
Detailed description of the invention
As it is shown in figure 1, the double-deck polypropylene composite materials sheet material of a kind of band printing, including polypropylene body 1 and top, there is print
The cast polypropylene layer 2 of brush layer 3, cast polypropylene layer 2 is compounded in polypropylene originally by double component solvent-free polyurethane adhesive 4
On body 1.
The thickness of double component solvent-free polyurethane adhesive 4 and cast polypropylene layer 2 ratio for 1:10, can guarantee that curtain coating poly-third
The effect that alkene layer is compound, bond properties is high, can be according to the cast polypropylene layer of different-thickness to double component solvent-free polyurethane glue
The thickness of glutinous agent is controlled, and Practical Performance is good, adapts to the demand of different product, can reduce coming off of cast polypropylene layer,
The thickness of cast polypropylene layer 2 is 40 μm, can guarantee that the drawing and forming performance of cast polypropylene layer, is conducive to printing the print of layer
Brush, on each square metre of interior polypropylene body 1, the quality of double component solvent-free polyurethane adhesive 4 is 2.8g, can strengthen
Combined strength bination, ensures and is unlikely in outward appearance and forming process to produce the problems such as layering, random distortions, the thickness of polypropylene body 1
It is 250～400 μm, can guarantee that polypropylene body has good deflection, plastics sucking moulding excellent performance, heat sealability good, and tool
The best barrier property.
During use, according to different product packagings, the printing layer 4 on curtain coating polypropylene layer 2 is printed, and good
Control the thickness of cast polypropylene layer 2, then by double component solvent-free polyurethane adhesive 4, cast polypropylene layer 2 is combined
On polypropylene body 1, then ripening 72 hours at a temperature of 45 DEG C, then cut into according to the space of a whole page width required for client
Coiled strip, it is provided that use to client.
In addition to above preferred embodiment, the present invention also has other embodiment, and those skilled in the art can be according to this
Invention is variously modified and deforms, and without departing from spirit of the present utility model, all should belong to right appended by this utility model
Require defined scope.
