Problems solved by technology

At present, there is no general-purpose bitumen performance-enhancing product in various industries. Most manufacturers blend it by themselves according to their own production experience. The sources of materials used are different, and the quality varies greatly. There is no special bitumen blending product. Improper selection of materials leads to high blending costs, and there is no certain technical solution for blending, and it is difficult to guarantee the quality of blended asphalt

Abstract

The invention discloses a universal asphalt performance enhancing agent. The universal asphalt performance enhancing agent comprises the following components according to mass percents: 20-60% of furfural oil, 30-70% of heavy oil and 2-30% of dioctyl phthalate. Simultaneously, the invention discloses a preparation method of the universal asphalt performance enhancing agent and comprises the following steps of: matching according to the mass percents of the components of the universal asphalt performance enhancing agent stated in the claim 1, sequentially adding the furfural oil, the heavy oil and the DOP to a reaction kettle, stirring, rising a temperature till reaching 80 to 100 DEG C, preserving the temperature, stirring for 20-40min, and reducing the temperature till reaching a room temperature. The universal asphalt performance enhancing agent provided by the invention has the advantages that raw materials are easy to purchase, the quality is stable, the equipment investment is few, the processing speed is fast, the production is easy, the storage stability is good, the physicochemical property is stable, and the universal asphalt performance enhancing agent can be widely applied to various fields of asphalt processing industries.

Description

technical field [0001] The invention relates to a preparation method of a general-purpose asphalt performance-enhancing agent, which is processed by stirring and heating three materials, and can be widely used in engineering waterproofing, asphalt processing of new roads, aging asphalt pavement maintenance and other fields. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and non-metallic derivatives. It is a good waterproof, moisture-proof and anti-corrosion organic gelling material, and is widely used in waterproof, rubber, anti-corrosion and road paving industries. . [0003] Due to the wide variety of properties, asphalt needs to be improved when it is used. Although the technical terms and names are different in various industries, it can basically be referred to as blending and modifying asphalt. The purpose of changing the physical properties of asphalt is achieved through blending, making i...
