Water-dispersed acrylic pressure sensitive adhesive

Water-dispersed acrylate pressure-sensitive adhesive is made of butyl acrylate, 2-ethyl acrylate, ethyl acrylate, acrylic acid, initiator, viscosities, crosslinking agent, ammonia water, and other materials by reasonable preparation. Water dispersed acrylic pressure-sensitive adhesive is a new product of adhesive, its main characteristics are: easy to obtain raw materials, simple process, long storage period, easy to use, strong bond, water as a dispersion medium, does not use the emulsifier, but rely on the polymer itself emulsification, so as to avoid some shortcomings of emulsion polymer brought by an emulsifier. Mainly used for making pressure-sensitive tape.

The technical problem we need to solve is to overcome the defects of the existing technology, to provide a water-dispersed acrylic ester pressure-sensitive adhesive and its preparation method, it is easy to obtain raw materials, simple process, long storage period, convenient use, firm bond, water as the dispersion medium, do not use the emulsifier, but rely on polymer self-emulsification. Thus, some deficiencies of emulsion polymer brought by emulsifiers are avoided.

In order to solve the above problems, we can use the following technical solution: The following is a preparation method of water-dispersed acrylate pressure sensitive adhesive, the water-dispersed acrylate pressure sensitive adhesive prepared by the following weight ratio of raw materials: Butyl acrylate 72% ~ 75%, 2-ethyl ethyl acrylate 8.71% ~ 8.8%, ethyl acrylate 8.71% ~ 8.8%, acrylic acid 6.78% ~ 7%, initiator 0.1% ~ 0.7%, viscosifier 1.93% ~ 2%, crosslinking agent 0.58% ~ 0.65%, an appropriate amount of ammonia water.

The above is a water-dispersed acrylic pressure-sensitive adhesive of butyl acrylate, 2-ethyl acrylate, ethyl acrylate, acrylic acid, initiator, viscosities, crosslinking agent, ammonia water as the main component of the solid adhesive.
