Abstract
A kind of plastic core layer Cellular Networks hollow wall extrusion board moulding process, sheet material is three-decker, it is respectively internal layer, sandwich layer and outer layer, sandwich layer is the hollow structure that cross section honeycomb is netted, and described internal layer, sandwich layer and outer layer all cross after three Fluid Channel for Plastic Extrusion Die of an injection molding extruder are disposably extruded with plastic material and merge the integrated section bar of molding.This solution provides a kind of plastic core layer Cellular Networks hollow wall extruding pipe material moulding process, by an extrusion molding, save operation, and interlaminar strength is high, hermetic barrier performance is good, when cutting stress, impact shock, does not easily cause sealing-off or degumming aliquation.
Description
Technical field
The invention belongs to extruded plastic profile technology field, refer in particular to a kind of plastic core layer Cellular Networks hollow wall extrusion board and become
Type technique.
Background technology
At present plastic core layer Cellular Networks hollow wall sheet material is battenboard, battenboard first need respectively molding sandwich layer, internal layer and
Outer layer, then add thermal weld or gluing is bonding by laminating, secondary operations becomes plastic core layer Cellular Networks hollow wall battenboard section bar.Its
Interlaminar strength, hermetic barrier performance depend on welding or bonding quality.When cutting stress, impact shock, can cause de-
Weldering or degumming play layer defects.
Summary of the invention
It is an object of the invention to provide a kind of plastic core layer Cellular Networks hollow wall extrusion board moulding process, by once squeezing
Going out molding, to solve the problem in background technology, product quality is more preferable.
The object of the present invention is achieved like this: a kind of plastic core layer Cellular Networks hollow wall extrusion board moulding process, plate
Material is three-decker, respectively internal layer, sandwich layer and outer layer, and sandwich layer is the hollow structure that cross section honeycomb is netted, described internal layer, sandwich layer
All cross after three Fluid Channel for Plastic Extrusion Die of an injection molding extruder are disposably extruded fusion molding with plastic material with outer layer
Integrated section bar.
Preferably, the honeycomb hole axis of Cellular Networks is perpendicular to plate plane.
Preferably, the honeycomb hole axis of Cellular Networks is parallel to plate plane.
Preferably, the material that described internal layer, sandwich layer and outer layer use is identical, extrusion temperature and extrusion pressure identical.
The present invention is prominent and useful compared to existing technology has the technical effect that saving operation, and interlaminar strength is high, close
Separating performance of blockading is good, when cutting stress, impact shock, does not easily cause sealing-off or degumming aliquation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Reference: 1, internal layer；2, sandwich layer；3, outer layer；4, extrusion；5, carry-over pinch rolls.
Detailed description of the invention
With specific embodiment, the invention will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of plastic core layer 2 Cellular Networks hollow wall extrusion board moulding process, sheet material is three-decker, point
Not Wei internal layer 1, sandwich layer 2 and outer layer 3, sandwich layer 2 is the hollow structure that cross section honeycomb is netted, and described internal layer 1, sandwich layer 2 and outer layer 3 are equal
Crossing after three Fluid Channel for Plastic Extrusion Die of an injection molding extruder are disposably extruded with plastic material, it is integrated to merge molding
Section bar.The stepped distribution of extrusion 4, respectively molding internal layer 1, sandwich layer 2 and outer layer 3, three crosses after merging and leads through carry-over pinch rolls 5
It is stretched into type.
Wherein, the honeycomb hole axis of Cellular Networks is perpendicular to plate plane.This structure then sheet material anti-pressure ability is good, and intensity is high.
Or, the honeycomb hole axis of Cellular Networks is parallel to plate plane, this structural panel good toughness.
Wherein, the material that internal layer 1, sandwich layer 2 and outer layer 3 use is identical, extrusion temperature and extrusion pressure identical.The most sharp
Bonding between each layer, is not easily stripped.
Above-described embodiment is only presently preferred embodiments of the present invention, limits the scope of the invention the most according to this, therefore: all depend on
The equivalence change that the structure of the present invention, shape, principle are done, within all should being covered by protection scope of the present invention.
