1、 Introduction to Asphalt Deodorant

By using chemical synthesis methods, organic compounds are generated, which have high biological activity and strong decomposition ability. At a certain temperature, they react with harmful components in asphalt to generate harmless polymer compounds and reduce the content of harmful substances.

2、 Mechanism of asphalt deodorizer action

When the temperature of asphalt deodorant is above 140 ℃, it can react chemically with sulfur, nitrogen and other heteroatoms in asphalt, convert them into high boiling compounds, lock in harmful substances in asphalt, inhibit the generation and volatilization of harmful substances such as H2S, SO2, NOX, etc., reduce the emission of unpleasant gases generated by high-temperature oxidation and light component volatilization of asphalt, and improve the production and construction environment of asphalt and asphalt mixtures.

4、 Method of using asphalt deodorant

Heat the asphalt to 180 ℃ in a storage tank with a stirrer, add a deodorant, and stir for 30 minutes to produce environmentally friendly and odorless asphalt. When producing modified asphalt, the deodorant and modifier (SBS, rubber powder) can be pre mixed in proportion before being added together. After mixing with asphalt, the generation of harmful gases in the production of modified asphalt can be reduced through stirring.

5、 Application field of asphalt deodorant

Suitable for modified asphalt production, asphalt mixture production, and urban road asphalt mixture paving, especially with significant inhibitory effect on the odor of rubber asphalt.
