Embodiment 1

[0029] First take road petroleum asphalt SK90 # 60 parts, put into the melting furnace to melt, dehydrate, remove impurities, and then keep warm at 120°C for later use;

[0030] Separately mix 37 parts of water with 3 parts of quaternary ammonium salt emulsifier, add appropriate amount of hydrochloric acid, adjust the pH to about 1.5, and then heat it to 75°C, then mix the heated emulsifier aqueous solution with asphalt, and put it into the emulsification In the machine, the material can be filtered and discharged after pressurization, shearing and grinding for 10-15 minutes, and the outlet temperature of the emulsified asphalt should not be higher than 85°C during the process;

[0031] Add 10 parts by weight of natural rubber latex (NR) into 90 parts of emulsified asphalt, stir at a low speed for 6-25 minutes, and stir evenly to obtain modified emulsified asphalt;

[0032] Take 100 parts of modified emulsified asphalt, and pour 15 parts of photocatalytic composite agent anat...

Embodiment 2

[0034] First, take 35 parts of 60# petroleum asphalt and 15 parts of 10# petroleum asphalt and add them to the melting pot to melt, dehydrate, remove impurities, and then keep warm at 140°C for later use;

[0035] Add another 50 parts of water into the emulsification kettle, heat up to about 60°C, add 5 parts of ethylene oxide diamine emulsifier, stir and mix evenly, add appropriate amount of hydrochloric acid, adjust the pH to about 2, and slowly add After the melted asphalt is added, stir for 10-15 minutes to filter and discharge;

[0036] Add 10 parts by weight of ethylene-vinyl acetate copolymer emulsion (EVA) to 95 parts of emulsified asphalt, stir at a low speed for 6-25 minutes, and stir evenly to obtain modified emulsified asphalt;

[0037] Take 100 parts of modified emulsified asphalt, and pour 15 parts of photocatalytic material rutile TiO 2 , continue stirring at room temperature at a speed of 300-400rpm, after about 40 minutes of stirring evenly, pour 7 parts of d...

Abstract

The invention discloses a pavement tail gas degradation fog sealing layer material and a preparation method thereof. The material comprises the following ingredients in parts by weight: 80 to 100 parts of emulsified asphalt, 5 to 20 parts of modifying agents, 5 to 15 parts of photocatalytic complexing agents, 3 to 7 parts of plasticizers, 0.05 to 0.15 part of tackifiers and 150 to 200 parts of quartz sand, wherein the emulsified asphalt comprises 55 to 60 parts of petroleum asphalt, 2 to 3 parts of emulsifying agents, 37 to 43 parts of water and a proper amount of hydrochloric acid. The pavement tail gas degradation fog sealing layer material and the preparation method have the advantages that harmful gas of oxynitrides in automobile tail gas can be effectively degraded, meanwhile, the pavement preventive maintenance aspect is considered, the early-stage slight damage of the pavement surface is restored, and the water-resistant and anti-slip performance of the pavement is improved.

Description

technical field [0001] The invention relates to a pavement environmental protection and maintenance material, in particular to a material capable of effectively degrading harmful nitrogen oxide gases in automobile exhaust, taking into account the scope of preventive maintenance of the road surface, repairing the initial slight damage of the road surface, and improving the water resistance and anti-skid performance of the road surface Exhaust gas degradation mist sealing layer material and preparation method thereof. Background technique [0002] With the development of the economy and the progress of the society, the number of automobiles in our country has increased sharply. As of the end of 2014, the number of motor vehicles in my country reached 264 million, of which 154 million were automobiles. Vehicle exhaust pollution has become one of the main sources of air pollution. Scientific analysis shows that automobile exhaust contains a large number of harmful substances, i...
