Embodiment
The present invention will be described in detail with reference to the accompanying drawings and examples.
Refering to Fig. 1, for the waterproof foam structure of electronic equipment, including be cascading the first diaphragm, first
Glue-line, foamed cotton layer, PET film, the second glue-line and the second diaphragm.
Described foamed cotton layer include multiple equally distributed independent abscesses, the abscess be closed pore, the abscess it is straight
Footpath is 40-60 μm.The present invention uses above-mentioned closedcells structure, prevents the bilevel medium of foamed cotton layer from entering by foamed cotton layer
Row is linked up, and not only with flexibility but also can prevent the infiltration of water and moisture,.When by shock loading, abscess it is loaded effect and
Compression, produces a kind of viscous flow phenomenon, this compression, resilience and viscous flow phenomenon can consume shock loading energy, therefore show excellent
Different damping, buffering ability.
The density of the foamed cotton layer is 0.002-0.02g/cm3。
The present inventor has found by numerous studies, the first diaphragm that waterproof foam structure includes being cascading, the
One glue-line, foamed cotton layer, PET film, the second glue-line and the second diaphragm, foamed cotton layer use closedcells structure, rationally control abscess
Diameter and foamed cotton layer density, resulting foam structure water resistance is good, and classification of waterproof reaches IPX8, while having good
Good damping, buffering performance.
First diaphragm and the second diaphragm are made up of PET material.
The foamed cotton layer is made up of expanded material, it is preferable that described foamed cotton layer uses polyethylene foam-material or rubber
Expanded material or polyurethane foam material are made, it is highly preferred that the foamed cotton layer is made of acrylic-nitrile rubber expanded material.
First glue-line and the second glue-line are made of adhesive, and the adhesive is a kind of selected from following pressure-sensitive adhesive
Agent：In acrylic acid adhesive, silicon adhesive, rubber Hot-melt adhesive, acrylic acid series copolymer, rubber acrylic based copolymer
One kind or its above-mentioned any combinations.Preferably, first glue-line and the second glue-line are made of acrylic resin, and it is low
Do not soften under not embrittlement, high temperature under temperature, cohesive force is strong, can closed combination with plastic metal glass.
The thickness of first glue-line and the second glue-line is 10 μm, and the thickness of the PET film is 25 μm, the foamed cotton layer
Thickness be 100-1000 μm, the thickness of first diaphragm and the second diaphragm is 30-100 μm.
Silk-screen or ink is coated with the surface of the PET film, to meet different purpose color personalized customization demands such as
Mark, fool proof etc..There is another PET film good air-tightness can increase the water resistance of foamed cotton layer, and PET pliability can play guarantor
Waterproof action can also be played during shield foam damage layer.
The foamed technique of foamed cotton layer and PET film is integrally formed.With foam integrator after PET foaming, layering is difficult.
The foam structure segment difference absorption affinity of the present invention is strong, and foamed cotton layer pliability is strong and coordinates the viscosity of glue-line that we can be achieved
Segment difference absorption affinity or the segment difference viscosity of case foam structure, can be applied to the edge of segment difference.
Foam structure good water-proof effect, the cushioning ability of the present invention is good, is widely used in the electricity such as smart mobile phone, tablet personal computer
In sub- equipment.
