Description

technical field [0001] The invention relates to an emulsion-type acrylate pressure-sensitive adhesive and a preparation method thereof, belonging to the field of chemistry. Background technique [0002] In the existing technology, a pressure-sensitive adhesive refers to an adhesive that does not need to add a curing agent or solvent, nor does it need to be heated, and only needs to apply a little contact force to achieve bonding. Its characteristics are that it is easy to stick, not difficult to remove, and it is not damaged when peeled off. The adhesive layer will not dry for a long time, so it is also called self-adhesive. The acrylic pressure-sensitive adhesive is a kind of adhesive that develops very rapidly. It has excellent pressure sensitivity and adhesion. Because its molecular structure does not contain saturated bonds, it has aging resistance, light resistance and water resistance. It is widely used. to packaging, automotive, electronics and other fields. Traditi...
