Example Embodiment

[0029] Example 1

[0030] Put 30 grams of lignin and 6 grams of epichlorohydrin into the reaction kettle, start stirring and raise the temperature to 75°C for 2 hours, and the reaction pressure rises to 0.15MPa, then add 51 grams of tallow diamine, and then heat to 150°C for reaction 3. After hours, the temperature was increased to 180°C for 2.5 hours, and then the temperature was increased to 220°C for 3 hours, and the reactant was cooled to 70°C, and the lignin amine salt was obtained by discharging. 30 grams of the prepared lignin amine salt and 210 grams of industrial water are added to the dissolving equipment, and the mixture is stirred and dissolved at a temperature of 54-56°C. Then 10.9 grams of octylphenol polyoxyethylene ether (OP-10, 70% content), 0.08 grams of amine anti-stripping agent, and 10 grams of hydrochloric acid with a mass concentration of 37% are sequentially added to the dissolving equipment, and stirred After homogenization, 260.98 grams of asphalt mixtu...

Example Embodiment

[0031] Example 2

[0032] The other operating conditions of this embodiment are the same as those of Embodiment 1, except that decanediamine is used instead of tallow diamine, and the amount of decanediamine is 43.4 grams.

Example Embodiment

[0033] Example 3

[0034] The other operating conditions of this embodiment are the same as those of embodiment 1, except that m-phenylenediamine is used instead of tallow diamine, and the amount of m-phenylenediamine is 33.5 g.

Abstract

The invention relates to a road repairing and building asphalt mixture warm-mixing additive, a preparation method thereof and a using method thereof. The warm-mixing additive consists of lignin amine salt, chloroepoxy propane, OP-10, an amine anti-stripping agent, chlorhydric acid and industrial water. The preparation method comprises the following steps: preparing the lignin amine salt from lignin, the chloroepoxy propane and polyamine, and dissolving the lignin amine salt in water; and based on the mass of the solution, adding the OP-10, the amine anti-stripping agent and the chlorhydric acid into the solution, and uniformly stirring the mixture to obtain the warm-mixing additive. When used, the warm-mixing additive is mixed with asphalt; then the asphalt-containing warm-mixing additive is mixed with stones. The warm-mixing additive has the advantages that: warm-mixing additive which is a surfactant improves the state of the adhesion between the asphalt and the surfaces of the stones and the fluidity of the asphalt; and nitrogen, which serves as a hydrophilic radical in the amine, has very strong absorption force and adhesion force for the stones; environment-friendly and resource-saving production of changing waste into useful things and circularly using materials is realized because the lipophilic lignin is from extracts of wood paper-making liquid waste; and the production cost of the asphalt mixture is reduced.

Description

technical field [0001] The invention relates to a warm-mixing additive for road-building asphalt mixture and a preparation and use method thereof, belonging to the mixing technology of road-building asphalt mixture. Background technique [0002] There are usually two types of asphalt mixture mixing processes for road construction: hot mixing and cold mixing. The hot mixing process is to mix stone materials at a temperature of 178°C-182°C and asphalt at a temperature of 130°C-170°C to prepare asphalt mixture. This hot mixing process has high energy consumption, and the asphalt mixture mixed with this process is prone to thermal aging of asphalt and the emission of harmful gases after paving and rolling the pavement. The cold mixing process first makes asphalt into emulsion, and then mixes it with stone at a temperature of 20°C-35°C to prepare asphalt mixture. This cold mixing process has low energy consumption and has the advantages of environmental protection. The road sur...
