Then distinguished for having the high grade of transparency, the performance such as aging Dupont material.
Furthermore, containing urethano (NHCOO) and/or NCO (-NCO) in polyurethane (PU) strand.
Wherein NCO and the polarity of urethano, chemism are the strongest, therefore have good chemical adhesion, and have
The advantages such as the feel fragility that temperature resistance energy is excellent, resistance to ag(e)ing is high and good.
It is as noted previously, as composite bed 12 and there is polyurethane adhesive, and polyurethane adhesive can strengthen PET base material layer
11, the caking property between 13, thus can significantly extend the service life of fenestrated membrane 1, and fenestrated membrane 1 appearance looks elegant, without any glue stricture of vagina, gas
The open defects such as bubble, Pericarpium Citri tangerinae, that is effectively improve fenestrated membrane problem encountered in prior art.
Specifically, polyurethane adhesive includes polyurethane, tungsten trioxide nano particle, dispersant and solvent.At this
In embodiment, the dispersant used is sodium polyacrylate, and solvent is ethyl acetate, but the present invention is not limited thereto.Wherein,
Tungsten trioxide nano particle can further improve the heat-resisting effect of prepared fenestrated membrane.
In the present embodiment and other embodiments of part, the percentage by weight of polyurethane is 2%-5%, above-mentioned weight percent
Ratio is on the basis of the gross weight of solution.The percentage by weight of dispersant is such as 2%, 3%, 4%, 5%.
In the present embodiment and other embodiments of part, the percentage by weight of Tungstic anhydride. is 10%-20%, above-mentioned weight
Percentage ratio is on the basis of the gross weight of solution.Specifically, the percentage by weight of Tungstic anhydride. be such as 10%, 11%, 12%,
