Abstract
The invention discloses a waterproof foam. The waterproof foam comprises a foam layer, wherein an acrylic adhesive layer is respectively coated on each side of the foam layer, and a release film layer is attached to the surface of one of the acrylic adhesive layer. By adopting the structure, the waterproof foam has the advantages: 1, good airtightness; 2, good waterproofness; 3, good anti-aging performance; 4, excellent weather resistance; and 5, high binding strength.
Description
Technical field
The present invention relates to a kind of electronics, electrical equipment waterproof foam.
Background technology
At present, these outdoor electrical equipment such as mobile electronic device or sun power of mobile phone, panel computer, notebook computer etc. that China produces do not have water resistance, or water resistance is undesirable, once have water to immerse at once cause destruction.Even if some electronicss take seal approach; but because of structure existing problems or the irrationality of the material chosen or design; usually do not reach due sealing effectiveness; some employing joint strips (sheet) or seal gum carry out seal protection, though have in the seal approach taked because adhesive tape (sheet) design unreasonable easily cause operational lack of standardization, have because seal gum operation too bother, have because careless omission etc. of Process of Applying Glue all can cause seepage or sealing imperfection.All can not use at the environment that moisture is larger even sometimes, in case stopping property difference causes equipment failure.
Summary of the invention
Technical problem to be solved by this invention is, for the deficiencies in the prior art, provides a kind of waterproof foam, to reach good sealing effect, object that water-repellancy is strong.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of waterproof foam, comprises foamed cotton layer, and the both sides of described foamed cotton layer are coated with acrylic glue-line respectively, and described wherein one deck acrylic film surface is covered with release film layer.
Described release film layer is the bilayer structure of innner and outer layer, and nexine scribbles heavily peels off parting agent layer, and skin scribbles gently peels off parting agent layer.
Described foamed cotton layer adopts unicellular structure.
Described foamed cotton layer adopts the material of acrylic acid material or poly material or isoprene-isobutylene rubber or the material of urethane to make.
The present invention adopts said structure, has the following advantages: 1, good airproof performance; 2, good waterproof performance; 3, anti-aging is good; 4 weathering resistancies are good; 5, bonding strength is high.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation;
Fig. 1 is lamination layer structure schematic diagram of the present invention;
In FIG, 1, foamed cotton layer; 2, acrylic glue-line; 3, nexine; 4, outer; 5, heavily parting agent layer is peeled off; 6, gently parting agent layer is peeled off.
Embodiment
A waterproof foam as shown in Figure 1, comprises foamed cotton layer 1, and the both sides of foamed cotton layer 1 are coated with acrylic glue-line 2 respectively, and wherein one deck acrylic glue-line 2 surface is covered with release film layer.Release film layer is the bilayer structure of innner and outer layer, and nexine 3 scribbles heavily peels off parting agent layer 5, and outer 4 scribble light stripping parting agent layer 6.Foamed cotton layer 1 adopts unicellular structure.Foamed cotton layer 1 adopts the material of acrylic acid material or poly material or isoprene-isobutylene rubber or the material of urethane to make.
The measure that the present invention takes carries out double spread to foam, and what foam adopted is unicellular structure, not only had flexibility but also can stop the infiltration of water and moisture; What separate-type paper adopted is the high-quality separate paper with two-sided release effect, and the inside one deck adopts and heavily peels off parting agent coating, outer employing gently peels off parting agent coating, the rolling that being designed with of this structure is beneficial to foam rubber adhesive tape and dissociating.Foam can adopt acrylic acid, poly, isoprene-isobutylene rubber, urethane etc. the material that can be used as foaming make.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the various improvement that technical scheme of the present invention is carried out, or directly apply to other occasion, all within protection scope of the present invention without improving.
