Problems solved by technology
[0003] However, the modified asphalt currently on the market has the following problems in the process of preparation: a. When the modified asphalt is prepared, the heavy viscous after distillation The substance is easy to remain on the inner wall of the distillation tank, thus affecting the distillation of the solution
b. After scraping off the heavy sticky matter remaining on the inner wall of the distillation tank, the heavy sticky matter cannot be smoothly discharged from the distillation tank

Embodiment Construction
[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0034] see Figure 1-10 As shown, a method for preparing modified asphalt, the method for preparing modified asphalt specifically includes the following steps:
[0035] S1, distillation: first place the solution that needs to be prepared after the solid-liquid separation into the distillation tank 3, and then conduct heating distillation;
[0036] S2, cleaning: after the S1 step is completed, the heavy viscous material remaining on the inner wall of the distillation tank body 3 after distillation is scraped off at this time to prevent the heavy viscous materia...

The invention relates to a preparation method of modified asphalt. A workbench, a fixing device, a distillation tank body and a clearing device are involved. The fixing device comprises a supporting plate, an arc-shaped plate, a clamping plate, a rubber pad, a first threaded rod and a pressure spring. Through the arrangement of the workbench, the fixing device, the distillation tank body and the clearing device, the distillation tank body is firstly placed on the fixing device, the distillation tank body is limited and fixed through the fixing device, at the moment, a solution needing to be prepared is placed into the distillation tank body, then heating distillation is performed, at the moment, heavy viscous materials remaining on the inner wall of the distillation tank body after distillation are scraped off by utilizing the clearing device, the heavy viscous materials are prevented from remaining on the inner wall of the distillation tank body, the distillation of the solution is not influenced, and the heavy viscous materials in the distillation tank body are smoothly discharged through the cooperation of the distillation tank body and the clearing device.
Description
technical field [0001] The invention relates to the field of modified asphalt preparation, in particular to a modified asphalt preparation method. Background technique [0002] Asphalt is a black-brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It usually exists in the form of liquid or semi-solid petroleum. The surface is black and soluble. Carbon disulfide, carbon tetrachloride. Asphalt is a waterproof, moisture-proof and anti-corrosion organic cementitious material. Asphalt can be mainly divided into coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking, and petroleum pitch is the residue after crude oil distillation. Natural asphalt is stored underground, and some form mineral layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics, rubber and other industries, as ...
