preparation example Construction

[0038] In the preparation method of the described bio-asphalt of the present invention, wherein the combination scheme of distillation process, extraction process, oxidation process and blending process is preferably:

[0039] (1) The bio-oil is first processed by distillation process to obtain the intermediate product of bio-asphalt, and then processed by oxidation process to obtain bio-asphalt;

[0040] (2) The bio-oil is first processed by distillation process under different conditions to obtain different bio-asphalt intermediate products, and then the different bio-asphalt intermediate products are processed by blending process to obtain bio-asphalt;

[0041] (3) Bio-oil is first processed by distillation process to obtain bio-asphalt intermediate product 1, and then processed by oxidation process to obtain bio-asphalt intermediate product 2, and then bio-asphalt intermediate product 1 and bio-asphalt intermediate product 2 are processed by blending process to obtain bio-a...

preparation example 1

[0084] Using an atmospheric distillation device, 1000g of bio-oil is gradually heated to 150°C, and the bio-oil fraction with a boiling point greater than 150°C is separated; the time is 6.5h, and then the distillation product is aged in the oxidation tower for 0.5h to make the fraction obtained from distillation Bio-asphalt was obtained by sufficient thermo-oxidative aging.

[0085] The bio-asphalt and rubber oil obtained above were stirred at 140°C for 2 hours at a ratio of 9:1 to obtain bio-asphalt composition 1.

Abstract

The invention provides a modified biological asphalt material, a biological asphalt mixture, a preparation method thereof and applications. The modified biological asphalt material is prepared by a mixture of a biological asphalt compound, a modifying agent, a compatilizer and a stabilizing agent. The preparation method is simple and easy to practice, the pollution is low in a production process, and raw materials are simple and easy to obtain. The obtained modified biological asphalt material can be directly used as road asphalt for mixture production. The biological asphalt mixture and the preparation method thereof are provided, and the obtained biological asphalt mixture can be used for paving roads.

Description

technical field [0001] The invention relates to the technical field of asphalt for road engineering, in particular to a modified bio-asphalt material, a preparation method and application thereof, and also relates to a bio-asphalt mixture and a preparation method thereof. Background technique [0002] Petroleum asphalt is derived from petroleum, and its resources are decreasing day by day, which will inevitably make petroleum asphalt increasingly scarce. Due to the current overexploitation and use, oil resources are about to face the danger of depletion. Scientists predict that by the middle of this century, that is, around 2050, oil resources will be exhausted. [0003] The current situation of petroleum resources and the problems of environmental development force us to constantly search for and apply new and renewable alternative materials. At present, the biomass energy researched and developed by the whole world is an inexhaustible and inexhaustible renewable energy. ...
