Beschreibung
Zusammenfassung:	The invention belongs to the technical field of an adhesive and specifically relates to a pressure-sensitive adhesive and its preparation method. The pressure-sensitive adhesive is composed of main rubber, an auxiliary additive, a tackifier, a plasticizer and a solvent, wherein the main rubber is composed of natural rubber and synthetic rubber, and the auxiliary additive comprises 2402 resin, an antioxidant and pigment and filler. By acrylic rubber compounding, temperature resistance of the main rubber is enhanced. By using 2402 resin as a cross-linking agent, temperature resistance and moisture resistance of the pressure-sensitive adhesive are raised. A prepared adhesive tape is pasted normally in saturated steam of 150 DEG C for 30 min and there exists no degumming or shedding phenomenon.
