Abstract

The invention discloses road gap-filling cement and a preparation method of the road gap-filling cement, wherein the road gap-filling cement is composed of following components in percentage by weight: 50-80% of bitumen matrix, 3-19% of modifier and 3.1-41% of auxiliary additive. The preparation method is as follows: heating bitumen softener to 150-200 DEG C, adding butadiene styrene rubber and stirring uniformly; heating the bitumen matrix to 160-200 DEG C, adding styrene-butadiene-styrene block polymer, ethylene-vinyl acetate-chloroethylene graft copolymer and uniformly-stirred butadiene styrene rubber to the bitumen matrix at the temperature and stirring till dissolving completely; and then adding petroleum resin, rubber powder and stabilizer, finally, stirring uniformly. The aim of the invention is to overcome the disadvantages of the prior art, so that the road gap-filling cement with rational proportion, high-temperature stability and good anti-ageing performance, which can adapt to high temperature or low temperature, is provided. The other aim of the invention is to provide a method for preparing the road gap-filling cement.

Description

technical field [0001] The invention relates to a road caulking glue, and also relates to a method for preparing the road caulking glue. Background technique [0002] The formula of the existing road joint filler is relatively complicated, and its high-temperature stability and aging resistance are poor, and it is easy to become brittle and cracked when the temperature is low in winter. The connection is not good, it will move out in summer, the production cost is high, it contains triphenyl, and it pollutes the environment seriously. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and provide a road gap filler with reasonable formula, good high temperature stability and aging resistance, and adaptable to high temperature or low temperature. [0004] Another object of the present invention is to provide a method for preparing the above-mentioned road sealant. [0005] In order to achieve the above o...
