ANTI TIRE DISCOLORATION PROTECTIVE SOLUTION AND PREPARATION METHOD THEREFOR

The present invention relates to the technical field of tire additives, in particular to an anti tire discoloration protective solution capable of being cured at room temperature and having super-strong weather resistance, and a preparation method therefor. The protective solution is composed of components (in parts by weight): 15-25 parts of a waterborne epoxy resin, 20-35 parts of a toughened waterborne resin, 0.5-2.5 parts of a modifier, 1-2 parts of a reactive ultraviolet absorbent, 1-3.5 parts of an active agent, 2.6-5.5 parts of other additives such as a coalescing agent, 0-6 parts of a pigment filler, 0.05-0.2 part of a degerming agent and 40-60 parts of deionized water, and under a stirring condition, adding 0.4-1.6 parts of a curing aid, 0.05-0.5 part of a stabilizer and 0.1-0.8 part of a thickening agent, stirring for a certain period of time, and filtering to obtain a protective solution. The present high-molecular-weight waterborne epoxy resin / toughened waterborne resin compound provides a certa
