| titleOfInvention | Styrene-butadiene latex and preparation method and application thereof |
| abstract | The invention belongs to the field of asphalt modifiers, and particularly relates to styrene-butadiene latex as well as a preparation method and application thereof. The preparation method provided by the invention comprises the following steps: a) mixing an emulsifier, a molecular weight regulator, a dispersing agent, a free radical stabilizer, an electrolyte and water, regulating the temperature, and adding butadiene, styrene, a tertiary amine monomer and an initiator into a mixed system to react when the temperature of the mixed system reaches 5-15 ℃; b) after the reaction is carried out for 4-6 h, adding a cross-linking agent into the reaction system, and then heating to 20-40 ℃ to continue the reaction for 0.5-2 h; c) and after the reaction is finished, mixing the obtained reaction product with an anti-aging agent, and degassing to obtain the styrene-butadiene latex. The method provided by the invention adopts a low-temperature and high-temperature two-stage method for polymerization, and adds a proper amount of tertiary amine monomer for copolymerization and a proper amount of organic matter containing active halogen groups as a cross-linking agent, so that the prepared styrene-butadiene latex has higher solid content and excellent asphalt modification capability. |
