Abstract

A kind of method for compressing filling foam, including;The die cavity filled as required, monoblock foam is cut, and is cut into the foam of strip;Using sealing effectiveness:The PE films of year leak rate≤5%, PE films are wrapped in outside strip foam, are sealed along foam length direction and made, indwelling two ends non-closed state;Vacuumized from two ends using vaccum-pumping equipment, exhaust rear two ends sealing.The foam that use this patent of the invention is used is from elastic good, fire protecting performance foam material high, the cross-sectional area for installing die cavity to be filled cuts, coated and vacuumized with the PE films of high sealing performance, compression foam is formed, the sealing PE films that only need to dismantle when being filled into die cavity can just complete to install with self-expansion.The space of transport storage foam can be reduced;Without the foam of large volume directly is filled in into the time required for die cavity reduces installation.

Description

A kind of method for compressing filling foam
【Technical field】
The present invention relates to packing material field, more particularly to by the way of compression foam is filled.
【Background technology】
Foam is divided into PU foams, antistatic foam, conducting foam, EPE, antistatic EPE, PORON, CR, EVA, bridge formation PE, SBR, EPDM etc., with easy to use, bending freely, a series of features such as the ultra-thin, dependable performance of volume.Using its is flexible, Lightweight, fire-proof and damp-proof characteristic can be as buffering, heat-barrier material very well.The present invention be directed to foam is applied into filling material Material field, prior art is usually the shape that foam is cut into the die cavity for needing filling, is then directly plugged into die cavity, because It is foam characteristic in itself, it is bulky in there is installation difficulty, storage and transportation in filling processing.
【The content of the invention】
The present invention proposes a kind of reduction installation difficulty for case above, and installation, storage and transport are all eaily The construction method of compression filling foam.
The method of compression filling foam involved in the present invention, including;
The die cavity filled as required, monoblock foam is cut, and is cut into the foam of strip;
Using sealing effectiveness:The PE films of year leak rate≤5%, PE films are wrapped in outside strip foam, along foam length Direction envelope system, indwelling two ends non-closed state;
Vacuumized from two ends using vaccum-pumping equipment, after the 30% of foam bar volume contraction to initial volume, by PE films Two ends seal.
The shape of cross section of the foam for cutting is consistent with the cross section size of die cavity to be filled.
A kind of method for compressing foam filling, including;
The filling foam of compression is directly placed into die cavity, then the sealing at PE films two ends is dismantled;
The full die cavity of foam self-expansion filling, completes to install.
The foam that use this patent of the invention is used is treated from elastic good, fire protecting performance foam material high, installation The cross-sectional area for filling die cavity cuts, and is coated and is vacuumized with the PE films of high sealing performance, forms compression foam, is filled into die cavity When the sealing PE films that only need to dismantle can just complete to install with self-expansion.The space of transport storage foam can be reduced;Without straight Connect the time required for the foam of large volume is filled in into die cavity reduction installation.
【Brief description of the drawings】
Fig. 1 is present invention compression filling foam compression schematic diagram;
Fig. 2 is the schematic diagram that present invention compression filling foam fills die cavity;
Fig. 3 is the schematic diagram of compression foam self-expansion of the invention;
Wherein:1O, 10 ', foam;20th, PE films.
【Specific embodiment】
The present invention is described in further detail below in conjunction with the drawings and specific embodiments of the present invention.
Prior art, because of foam material property in itself, is deposited in transport, work progress to transport and the installation of small space In difficulty.In actual use, when having steam or water in die cavity, foam can absorb moisture, itself insulation, anti-acoustic capability Reduce.According to compression method of the invention, because volume diminishes after compression, transport installs all more convenient, can be certainly after installation Row expansion, plays a part of to fill die cavity.In addition, there is the protection of PE films, foam can be prevented from absorbing water, can for a long time protect foam Insulation, Noise Reduction.
Such as accompanying drawing 1, the method for compression filling foam involved in the present invention, including;
The die cavity filled as required, monoblock foam is cut, and is cut into the bubble 10 of strip;The horizontal stroke of the foam for cutting Cross sectional shape is consistent with the cross section size of die cavity to be filled.
Using sealing effectiveness:The PE films of year leak rate≤5%, PE films 20 are wrapped in outside strip foam 10, along foam 10 length directions envelope system, indwelling two ends non-closed state;
Vacuumized from two ends using vaccum-pumping equipment, after the 30% of foam bar volume contraction to initial volume, by PE films Two ends seal, the foam 10 ' as compressive state.
A kind of method for compressing foam filling, including;
As in Fig. 2, the filling foam 10 ' for compressing is directly placed into die cavity, then the sealing at PE films two ends is dismantled;
The full die cavity of foam self-expansion filling, completes to install.Installation effect figure after as being expanded such as accompanying drawing 3.
The foam that use this patent of the invention is used is treated from elastic good, fire protecting performance foam material high, installation The cross-sectional area for filling die cavity cuts, and is coated and is vacuumized with the PE films of high sealing performance, forms compression foam, is filled into die cavity When the sealing PE films that only need to dismantle can just complete to install with self-expansion.The space of transport storage foam can be reduced;Without straight Connect the time required for the foam of large volume is filled in into die cavity reduction installation.
The above, is only present pre-ferred embodiments, and any formal limitation is not made to the present invention, although The present invention is disclosed above with preferred embodiment, but is not limited to the present invention, any those skilled in the art, Do not depart from the range of technical solution of the present invention, be equal to when making a little change or being modified to using the technology contents of the disclosure above The Equivalent embodiments of change, as long as it, without departing from technical solution of the present invention content, refers to implement to more than according to the technology of the present invention to be Any simple modification, equivalent variations and modification that example is made, belong in the range of technical solution of the present invention.

Claims (2)

1. a kind of method that foam is filled in compression, including;
