Double-sided pressure sensitive adhesive tape capable of movement in short time, and preparation method thereof

Abstract

The invention discloses a double-sided pressure sensitive adhesive tape capable of free movement in a short time, and a method thereof. The adhesive tape comprises two adhesive layers, wherein the surface of an adhesive layer is covered with 5-10 / cm<2> microbeads, and the surface of the adhesive layer is covered with release paper. The adhesive layers are the pressure sensitive adhesive layers. The preparation method for the tape comprises: mixing 2-ethylhexyl acrylate and an acrylic acid monomer, adding a certain monomer weight of azobisisobutylnitrile, and dissolving in ethyl acetate to obtain a mixed solution; in the case of nitrogen introducing, carrying out a reaction for 8 hours at a temperature of 60-65 DEG C to obtain an acrylate polymer; adding a cross-linking agent to the solution, and uniformly mixing; coating the adhesive solution on the silicone treated release paper, and conveying to a baking oven to carry out drying, wherein the temperature is 100 DEG C, and the time is 5 minutes; adhering the adhesive layer to the substrate after completing the drying, wherein the thickness of the adhesive layer after the drying is 70-80 mum; preparing a dried adhesive film by the same method, and uniformly spraying the microbeads with the diameter of 10-30 mum on the adhesive surface after the adhesive film is adhered to the substrate, wherein each square centimeter of the adhesive surface is sprayed with 5-10 of the microbeads, and the release paper is compounded on the adhesive layer after completing the microbead spraying.

Description

technical field [0001] The invention relates to a pressure-sensitive adhesive tape, in particular to a double [0002] Surface pressure sensitive adhesive tape and preparation method. Background technique [0003] At present, the double-sided pressure-sensitive adhesive tapes used for fixing articles mainly include double-sided adhesive tapes with foam substrates, double-sided adhesive tapes without substrates, double-sided adhesive tapes with film substrates, and textile or non-textile substrates. Double sided adhesive tape. One of these double-sided adhesive tapes is used for temporary sticking, and is easy to remove after use. The other type is for permanent fixation. After the adhesive tape is pasted, it cannot be removed. Even if it can be removed, it will cause damage to the adhesive or the adhesive tape. It is difficult to clean up the residue after the adhesive tape is damaged. The pressure-sensitive adhesive used in the double-sided adhesive tape is generally ac...

AI Technical Summary

Problems solved by technology

Since the adhesive layer of the ordinary double-sided adhesive tape achieves effective bonding with the bonding surface in a short period of time, the adhesive tape cannot be moved without damage when the initial pasting position is wrong and needs to be adjusted. Rework in a destructive manner, resulting in material waste and reduced production efficiency
