Technical Field

The invention relates to the technical field of water-soluble pressure-sensitive adhesive construction, in particular to a construction process of a water-soluble pressure-sensitive adhesive.

Background

Pressure-sensitive adhesives are short for pressure-sensitive adhesives. Is a type of adhesive that is sensitive to pressure. The preparation method is mainly used for preparing the pressure-sensitive adhesive tape. The pressure-sensitive adhesive must have a higher adhesive force (the peeling force exhibited after the pressure-sensitive adhesive tape is pressure-adhered to the adherend surface) than cohesive force (i.e., so-called sticky feeling exhibited when the adhesive tape is lightly touched with a finger). It can be classified into rubber type and resin type according to its main component. Besides the main components, other auxiliary components such as tackifying resin, plasticizer, filler, viscosity regulator, vulcanizing agent, anti-aging agent, solvent and the like are added to prepare the adhesive. The existing preparation process of the water-soluble pressure-sensitive adhesive is complex and needs to be improved.
