Abstract

The invention discloses an acrylic acid pressure-sensitive adhesive tape and a preparation method thereof. The method comprises the following steps: providing an acrylic pressure-sensitive adhesive, wherein the acrylic pressure-sensitive adhesive comprises an acrylic soft monomer, a hard monomer, an acrylic functional monomer, an initiator and an organic solvent; mixing the acrylic pressure-sensitive adhesive, amino resin, organic acid and an organic solvent to obtain a mixed solution; and coating a base material with the mixed solution, and drying to obtain the acrylic acid pressure-sensitive adhesive tape. Amino resin is adopted as a curing agent, organic acid is matched to serve as a catalyst, traditional curing agents such as isocyanate and epoxy resin needing to be cured are replaced, online curing is achieved in the coating and drying process, and therefore the delivery time is shortened, and input of sites and energy is reduced.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to an acrylic pressure-sensitive adhesive tape and a preparation method thereof. Background technique [0002] At present, the common acrylic pressure-sensitive tapes on the market use isocyanate curing agent or epoxy curing agent in the coating process. After coating, they need to be cured in an environment of about 40-60°C for 3-7 days. This will greatly increase the production cycle, thereby increasing the cost of time, space and energy. [0003] Therefore, the prior art still needs to be improved and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the object of the present invention is to provide an acrylic pressure-sensitive adhesive tape and a preparation method thereof, aiming at solving the problem of long production cycle of the existing method. [0005] Technical scheme of the present invention is as follows: ...
