The invention relates to a removable hot-melt pressure-sensitive adhesive and belongs to the technical field of adhesives. The pressure-sensitive adhesive is prepared from raw materials in parts by mass as follows: 35-45 parts of matrix resin, namely, a styrene-isoprene-styrene triblock copolymer, 30-40 parts of a tackifier, namely, C5 petroleum resin, 8-13 parts of a softener, namely, dioctyl terephthalate, 3-8 parts of a peel strength modifier, namely, polyethylene wax, 7-15 parts of a viscosity modifier, namely, liquid petroleum resin, 0.6-1.4 parts of an antioxidant and 0.4 parts of an ultraviolet absorbent. An adhesive tape prepared from the pressure-sensitive adhesive can be peeled and pasted repeatedly, and the adhesive cannot be transferred after the pressure-sensitive adhesive is pasted with paper, PE films, PP films and the like. The pressure-sensitive adhesive meets the environmental protection requirement of European Union REACH and RoHS on the basis of detection of specialized agencies and can completely meet the requirement of production of sealing labels, labels and removable adhesive bags.
