Description
Technical Field
The invention relates to a pressure-sensitive adhesive tape and a preparation method thereof, in particular to a high-bonding-strength chemical-resistant polyacrylate adhesive tape with a patterned adhesive area and a preparation method thereof.
Background
Pressure-sensitive adhesive tapes are tapes that are pressure-sensitive by applying a pressure-sensitive adhesive to a substrate (PET, PC, PI, etc.). Because the pressure-sensitive adhesive tape has the advantages of high bonding strength, high bonding speed, simple and convenient operation and the like, the pressure-sensitive adhesive tape is widely applied to the manufacture and the assembly of buildings, automobiles, electric appliances and 3C products. The polyacrylate pressure-sensitive adhesive occupies a leading position in a pressure-sensitive adhesive product based on the advantages of high bonding strength, good weather resistance, easy performance adjustment and the like.
But polyacrylate pressure-sensitive adhesives generally have poor resistance to acids, bases and solvents due to the influence of the chemical structure of the polyacrylate itself. When the polyacrylate adhesive tape contacts corrosive liquid, the liquid can permeate into the adhesive from the side surface of the adhesive tape, so that the adhesive swells, and the performance of the pressure-sensitive adhesive is damaged.
Generally, the chemical resistance of the polyacrylate pressure-sensitive adhesive, such as the corrosion solution of acid and alkali resistance and the corrosion of other solvents, can be effectively improved by increasing the crosslinking density of the pressure-sensitive adhesive and strengthening the cohesive strength; accordingly, the critical properties such as initial adhesive property, adhesive strength and the like of the polyacrylate pressure-sensitive adhesive are greatly attenuated due to the great increase of the crosslinking density, so that the polyacrylate pressure-sensitive adhesive has high adhesive strength and high chemical resistance which are difficult to obtain.

The high chemical resistance glue areas are graphical glue areas which are connected with each other to form a network, and the high bonding strength glue areas are distributed among the network-shaped high chemical resistance glue areas in a sea-island shape.
Wherein the differentiated properties of the high bond strength glue regions and the high chemical resistance glue regions are achieved by differentiated UV cross-linking densities. The high-bonding-strength adhesive area is obtained in a first low-dose UV curing process through UV curing pressure-sensitive adhesive, and the high-chemical-resistance adhesive area is realized by carrying out second high-dose UV crosslinking on the high-bonding-strength adhesive area through a release film with an induced patterned light-transmitting area.
The release layer is a release film with an induced graphical light transmission area, namely a UV impermeable shielding area (202) is arranged on one side, far away from the glue layer, of the UV permeable release layer (201).
