Corrosion-resistant SBS modified asphalt formula

Abstract

The invention relates to a corrosion-resistant SBS modified asphalt formula which consists of the following raw materials: 75-90 parts of asphalt, 18-29 parts of SBS, 20-25 parts of butadiene styrenerubber, 6-10 parts of polyvinyl alcohol, 1-5 parts of a sodium hydroxide powder, 0.5-1.5 parts of vulcanized rubber, 3-10 parts of hexachloro-p-xylene, 4-9.5 parts of synthetic fatty acid, 4-9.5 partsof synthetic sodium aliphatate, 1-2.5 parts of borate mineral, 3-7 parts of castor oil, 0.5-3 parts of coal tar, 4-9.5 parts of phenyl salicylate, 1-3.5 parts of ortho-nitroaniline, 0.85-4 parts of asand powder, 2-5 parts of a polysulfide sealant, 1-3 parts of polycarbonate and 1-3 parts of polyacrylonitrile.

Description

technical field [0001] The invention relates to the field of chemical materials, in particular to a corrosion-resistant SBS modified asphalt formula. Background technique [0002] Many changes have taken place in modern highways and roads: the traffic flow and driving frequency have increased sharply, the axle load of freight vehicles has continued to increase, and lane-divided one-way driving is generally implemented. Water stability and elasticity also require the ability to resist cracking at low temperatures, improve wear resistance and prolong service life, so asphalt needs to be modified. Most of the modified asphalt adopts physical modification technology to realize the modification of asphalt by polymer, such as heating and stirring, shearing, colloid mill, etc. Although the method of physical modification can improve the performance of asphalt, the tensile ability, anti-ultraviolet ability and water stability after contact with water have not been fundamentally imp...
