Example Embodiment

[0018] Example 1.

[0019] The biomass heavy oil prepared from rice husks is processed at 110°C for 30 minutes (to remove moisture and small molecular volatiles), and the processed biomass heavy oil is transferred to a high-speed mixing and cutting machine, and then added to the processed 1wt% of epoxy resin by weight of biomass heavy oil, polyethylene of 10wt% by weight of processed biomass heavy oil, and polyethylene glycol 6000 of 0.5wt% by weight of processed biomass heavy oil; the resulting mixture High-speed mixing is carried out at a temperature of 80°C for 30 minutes to obtain a biomass pitch.

[0020] The biomass asphalt obtained above can be used to prepare waterproof materials.

Example Embodiment

[0021] Example 2.

[0022] The biomass heavy oil prepared from sawdust is processed at a temperature of 100°C for 150 minutes (to remove moisture and small molecule volatiles), and the processed biomass heavy oil is moved to a high-speed mixing and cutting machine, and then added to the processed 6wt% of epoxy resin by weight of biomass heavy oil, polyethylene of 1wt% by weight of processed biomass heavy oil, and polyethylene glycol 6000 of 12wt% by weight of processed biomass heavy oil to obtain a mixture; High-speed mixing is carried out at 80°C for 30 minutes to obtain biomass pitch.

[0023] The biomass asphalt obtained above can be used to prepare asphalt shingles.

Example Embodiment

[0024] Example 3.

[0025] The biomass heavy oil prepared from cotton stalks is processed at 110°C for 50 minutes (to remove moisture and small molecule volatiles), and the processed biomass heavy oil is moved to a high-speed mixing and cutting machine, and then added to the processed 3wt% epoxy resin, 6wt% polyethylene (new material or recycled material) of the treated biomass heavy oil, and 2wt% polyethylene glycol 6000 of the treated biomass heavy oil Mixture: The obtained mixture is mixed at a high speed at a temperature of 110°C for 30 minutes to obtain a biomass pitch.

[0026] The biomass asphalt obtained above can be used to prepare paving asphalt materials.

Abstract

The invention relates to asphalt, especially relates to biomass asphalt prepared by utilization of thermal cracking of biomass heavy oil, a preparation method for biomass asphalt and applications thereof. The biomass asphalt is composed of biomass heavy oil, epoxy resin, polyethylene and polyethylene glycol, wherein the epoxy resin is 1-6wt% of the biomass heavy oil in weight, the polyethylene is 1-10wt% of the biomass heavy oil in weight, and the polyethylene glycol is 0.5-12wt% of the biomass heavy oil in weight. The biomass asphalt can be used as a material for preparing pavement asphalt, a material of asphalt tiles, a waterproof material and the like. The utilization field of biomass heavy oil can be widened greatly, a high-efficiency and high-quality utilization mode is developed for biomass heavy oil, and products with high added values are generated.

Description

technical field [0001] The invention relates to asphalt, in particular to biomass asphalt prepared by pyrolysis of biomass heavy oil, and a preparation method and application of biomass asphalt. Background technique [0002] With the continuous growth of the world economy, energy and the environment have gradually become the bottleneck of economic development. The application of mineral energy has greatly promoted the development of society, but its storage capacity is decreasing day by day; at the same time, the unrestrained use of mineral energy has caused increasingly serious environmental problems, such as the greenhouse effect, global warming, and ecological balance. destruction and acid rain and other natural disasters. Therefore, the development and search for alternative energy sources of new fossil energy has become an important issue. Biomass energy has the advantages of renewability, wide distribution, and environmental friendliness. Through conversion technolog...
