Abstract

The invention relates to a smoke-suppressing deodorant for road asphalt, application of the smoke-suppressing deodorant in asphalt and a preparation method of asphalt. The smoke-suppressing deodorantis prepared from the following substance polymers, inorganic hydroxides, oxidizing agents and auxiliaries in parts by weight. The invention also discloses an application of the smoke-suppressing deodorant in modification of asphalt products, especially road asphalt, and the smoke-suppressing deodorant is especially used for suppressing smoke and removing odor in the paving construction process ofthe road asphalt, so that the health of construction personnel is protected; environmental protection.

Description

technical field [0001] The invention relates to a mixture capable of reducing smoke and odor of asphalt products, road asphalt based on the smoke suppressing and deodorizing agent and a preparation method thereof, belonging to the field of road asphalt material preparation, modification and application. Background technique [0002] With the continuous extension of highway mileage and the reconstruction of urban roads in our country, the demand for road asphalt is increasing year by year, especially the introduction of the new environmental protection law in 2015, which puts forward higher requirements for the quality of asphalt. Road asphalt will release a large amount of harmful substances in the process of mixing and paving. Even in the process of serving under normal temperature and pressure, the asphalt pavement will gradually release asphalt fumes, and the asphalt fumes released Volatile organic compounds mainly exist in the air in the form of aerosols, which are extre...
