Beschreibung
Zusammenfassung:	The invention relates to a resin preparation method at low temperature so as to improve rubber viscous and brightness of rubber product, and pertains to the petrochemical technical field. The main raw material and production process are that: styrene, cyclopentadienyl, polyketone or maleic anhydride modified rosin and metlbond are mixed with resin to produce the resin which can cause butyl rubber to have good initial adhesion and mutual viscosity as well as improve the surface brightness of rubber in the condition of -5 DEG C. The invention can produce hollow sealing joint strip resin, auto glass gland strip bonding resin, cold adhesion asphaltic resin, etc. Molecular weight of the resin is easily controlled by the preparation method of the invention, and the invention solves the problem of controlling molecular weight, steadily synthesizes resin and expands the application field of the production.
