Problems solved by technology

[0004] Most of today's aging asphalt regeneration agent patents mainly use heavy oil as the main raw material. Heavy oil is mainly petroleum residue, heavy distillate oil, coal tar, furfural oil, etc., and most of them are subsidiary products of petroleum and coal. Non-renewable resources, which have high preparation components and high resource consumption

Embodiment 1

[0024] The bitumen regeneration agent that present embodiment uses waste lubricating oil to produce is by removing impurity waste automobile lubricating oil, SEBS (with polystyrene as the end section, with the ethylene-butene copolymer obtained by hydrogenation of polybutadiene as the middle elastic Block linear triembedded copolymer, which belongs to common materials of asphalt modifier), dicumyl peroxide, C9 hydrogenated petroleum resin and carbon black are prepared according to the formula quantity, and the specific formula quantity is shown in Table 1.

[0025] The concrete preparation method of the asphalt regeneration agent that above-mentioned produces with waste lubricating oil is realized by following steps:

[0026] (1) Add NaOH solution with a mass concentration of 60% to the waste automobile lubricating oil, the NaOH solution accounts for 3% of the mass of the waste automobile lubricating oil, stir evenly and let stand for 25 minutes, heat to 75°C, let stand and set...

Embodiment 2

[0030] The asphalt rejuvenator prepared from waste lubricating oil in this example is prepared from impurity-removed waste gear oil, SEBS, straight-chain aliphatic hydrocarbons, C5 hydrogenated petroleum resin, and slaked lime according to the formula quantity. The specific formula quantity is shown in Table 1.

[0031] The concrete preparation method of the asphalt regeneration agent that above-mentioned produces with waste lubricating oil is realized by following steps:

[0032] (1) Add a NaOH solution with a mass concentration of 60% to the waste gear oil, the NaOH solution accounts for 2% of the waste gear oil mass, stir evenly and let it stand for 20 minutes, heat it to 70°C, let it settle for 20 hours, and take the supernatant Obtain de-impured waste lubricating oil;

[0033] (2) Heat the old lubricating oil for impurities removal to 110°C, add the formulated amount of SEBS, and initially swell for 28 minutes, then cut at a speed of 19,000r / min for 50 minutes, and swell ...

Embodiment 3

[0036] The asphalt rejuvenating agent prepared by the waste lubricating oil in this embodiment is prepared according to the formula quantity by de-impurity waste hydraulic oil, SEBS, stabilizer, petroleum resin and anti-aging agent, wherein the stabilizer is dicumyl peroxide and direct The chain aliphatic hydrocarbons are mixed according to the mass ratio of 1:2. The petroleum resin is made by mixing C5 hydrogenated petroleum resin and C9 hydrogenated petroleum resin according to the mass ratio of 1:1. The anti-aging agent is thiodipropionic acid two lauryl esters. See Table 1 for specific formula quantities.

[0037] The concrete preparation method of the asphalt regeneration agent that above-mentioned produces with waste lubricating oil is realized by following steps:

[0038] (1) Add NaOH solution with a mass concentration of 60% to the waste hydraulic oil, the NaOH solution accounts for 5% of the waste hydraulic oil mass, stir evenly and let stand for 30min, heat to 80°C,...

Abstract

The invention provides an asphalt regenerant prepared from waste lubricating oil and a preparation method for the asphalt regenerant. The asphalt regenerant is prepared by using waste lubricating oil as a main raw material, and adding SEBS, petroleum resin, an anti-aging agent and a stabilizer into the waste lubricating oil, so that not only can aged asphalt components be restored to the state before aging, but also the modified effect on recycled asphalt can be realized; an elastic space net structure is formed inside the asphalt regenerant, so that the regenerability of the whole regenerant is greatly improved, and moreover, the regenerant is low in environmental pollution, and is environment-friendly; in addition, the preparation method is simple and lower in cost.

Description

technical field [0001] The invention belongs to the technical field of research on aging asphalt rejuvenating agents, and in particular relates to a method for preparing aging asphalt regenerating agents by using waste lubricating oil as a raw material to realize waste reuse. Background technique [0002] my country's lubricating oil production accounts for about 2% of the total petroleum products, more than 2 million tons per year. With the further improvement of the country's industrialization level and the rapid development of the machinery industry, the amount of waste lubricating oil has also increased rapidly. If it is not handled properly, it will cause huge pollution to the environment. One liter of waste lubricating oil can pollute one million liters of clean water, which is equivalent to supplying drinking water for 14 people for a year. If simple incineration is used, it will also have a great impact on the environment. The State Environmental Protection Administ...
