Pressure sensitive adhesive for paper tape
Beauty strip paper tape in footwear, furniture, cars, home decoration, and other fields is widely used, the traditional beauty strip paper tape uses acrylic or silicone-modified acrylic acid, the advantage is low cost, but the disadvantages are also very significant, adhesion time is too long will produce degumming, migration, bonding drawing, and some need a higher temperature environment, acrylic can not meet the requirements.
At present, there are two categories of paper tape, one is acrylic as the bonding layer, one is silicone pressure-sensitive adhesive as the bonding layer, acrylic acid has a certain impact on the environment, and acrylic acid is not resistant to high and low temperatures, corrosion resistance and corrosion of copper, aluminum, silver, etc. (carboxyl, organic acid), smell bad. Because of the use of organic acids, they may attract insect bites. In some humid environments, the tape is not easy to use and store.
Silicone pressure-sensitive adhesive is inert and has high and low-temperature resistance, chemical corrosion resistance, good insulation performance, and excellent atmospheric aging resistance so it is widely used in the manufacturing of adhesive tape. Silicone tape is a big line in the field of adhesive tape. However, the high price of organosilicon will produce ghost, easy-to-form wire drawings when bonding, which is the problem faced in the practical application of such products.
Although silicone pressure-sensitive adhesive can solve these problems in a full range, due to the high permeability of the paper, unlike polyester, a polyimide film is flat, convex, and convex strong, resulting in glue permeability is particularly strong, on the one hand, it is easy to degum, ghost, made into tape softness is poor, when winding will collapse and spread, broken tape problems, need to be anti-penetration treatment, In the absence of anti-penetration treatment is easy to degum, ghosting. So the beauty paper as a protective film is very limited. But the paper can be reused, can save resources, and does not pollute the environment.
