It is necessary to invent a pressure sensitive adhesive for life test dosage

As a kind of adhesive material, tape has its special application, such as fixed bonding of materials, surface protection, and soon. With the faster and faster upgrading of the electronic industry, the requirements for electronic adhesive tape are becoming higher and higher. More electronic applications have put forward the requirements for adhesive tape to withstand the living substances in contact with life, such as laundry detergent, sweat, alcohol, food grease, etc., which are exactly the majority of ordinary adhesive tape can not tolerate.

It has been reported that a rubber belt company developed a kind of pressure sensitive rubber belt with good resistance to living reagents using nitrile rubber, but there are some problems such as low bond strength, poor ozone resistance, poor insulation performance, and low resilience. It has also been reported that the graft of acrylonitrile-butadiene styrene (ABS) with methacrylate can improve the impact resistance and life resistance of the material, but for electronic adhesive belts said that these ABS materials can not be applied to pressure sensitive adhesive products. Nowadays, how to improve the resistance of electronic adhesives to living reagents has been reported more and more.

At present, most of the tape on the market in addition to providing bonding properties is not resistant to life reagents in life. In recent years, a rubber belt company has developed a kind of double-sided rubber belt with resistance to the living reagents. The main material is an acrylonitrile-butadiene elastomer, which has excellent resistance to living reagents. However, the system products have some problems, such as hard hardness, low elasticity, low-temperature resistance, and ozone resistance. Therefore, it is necessary to seek a pressure sensitive adhesive and adhesive tape with high bond strength, good resistance to living reagents, good aging resistance, and suitable for the wide temperature range of applications. Therefore, it is necessary to invent a preparation method of pressure sensitive adhesive composition and its adhesive tape.
