Abstract

The invention relates to the technical field of petroleum asphalt preparation, and discloses a production method of SMA high-elastic modified asphalt for a steel bridge deck, which comprises the following working steps: 1, preparing a component A raw material; 2, preparing a component B raw material; and 3, mixing the component A raw material and the component B raw material according to a weight ratio of 1: (0.4-1.2). According to the production method of the SMA high-elastic modified asphalt for the steel bridge deck, anticorrosive petroleum asphalt is prepared by mixing a component A raw material and a component B raw material, and the component A raw material is prepared from 70 # asphalt, rosin soap, an emulsifier, sodium hydroxide, a defoaming agent, a thickening agent, water, bentonite, an epoxy curing agent, glass flakes and the like; the component B is prepared from the following raw materials: acrylic emulsion, styrene-butadiene latex, a defoaming agent, a coalescing agent, a flatting agent, an anti-flash-rust agent, a thickening agent, a solvent, a processing agent and the like, so that not only is the corrosion prevention efficiency of the petroleum asphalt improved, but also the adhesion efficiency of the petroleum asphalt is improved.

Description

technical field [0001] The invention relates to the technical field of petroleum asphalt preparation, in particular to a method for producing SMA high-elasticity modified asphalt for steel bridge decks. Background technique [0002] Petroleum asphalt has good adhesion, anti-aging and anti-corrosion ability, and has been used as anti-corrosion material for a long time. Used in anti-corrosion engineering, it has the advantages of easy availability of raw materials and low price. It is one of the most widely used materials in anti-corrosion engineering at home and abroad. The loss caused by metal corrosion is very serious, and coating anti-corrosion coatings is one of the main methods to prevent metal corrosion. [0003] With the increasing awareness of industrial environmental protection in my country, the existing anti-corrosion coatings are mainly solvent-based coatings, which contain a large amount of organic volatile substances, which not only cause harm to the health of ...
