The embodiment of the utility model provides a cotton sticky tape of bubble of anti-scratch, as shown in figure 1, include:
Adopt above-mentioned technical scheme, owing to set up anti layer 1 of scraping, will anti layer 1 of scraping coating on the cotton layer 2 of bubble, form the one deck protection film on the cotton layer 2 surface of bubble through anti layer 1 of scraping, consequently, improved the anti scratch performance of the cotton sticky tape of bubble, prevent that the cotton sticky tape of bubble from falling the bits because the scraping, and then cause the pollution for the product. In addition, due to the high adhesion and the stripping of the adhesive layer 4, the base layer 3 strengthens the foam layer 2, so that the reworkability of the foam adhesive tape is realized.
In a preferred embodiment, the scratch-resistant layer 1 has a thickness of 1 to 20 μm. Thus, a protective film can be formed on the surface of the foam layer.
Further, the scratch resistant layer 1 was 5 μm thick. This provides optimum scratch resistance and protection.
As a preferred embodiment, the scratch-resistant layer 1 consists of a fast-curing polymer coating. The polymer may be a modified acrylic resin.
The acrylic resin has the characteristics of light color, high transparency, brightness, fullness, tough coating film, strong adhesive force, corrosion resistance and the like, is a common coating material, is modified by utilizing organic silicon, organic fluorine, epoxy resin, polyurethane, nano materials and the like, further improves various performances, and has better scratch resistance effect.
