Embodiment 1

[0019] Treat the biomass heavy oil prepared from rice husk at a temperature of 110°C for 30 minutes (to remove moisture and small molecule volatiles), move the treated biomass heavy oil to a high-speed mixer, and then add the processed The epoxy resin of the biomass heavy oil weight 1wt%, the polyethylene glycol 6000 that is the biomass heavy oil weight 0.5wt% after the treatment and the polyethylene glycol 6000 that is the biomass heavy oil weight after treatment obtains mixture; The mixture obtained High-speed mixing was carried out at a temperature of 80° C. for 30 minutes to obtain biomass pitch.

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

Embodiment 2

[0022] Treat the biomass heavy oil prepared from wood chips at a temperature of 100°C for 150 minutes (to remove moisture and small molecule volatiles), move the treated biomass heavy oil to a high-speed mixer, and then add the processed The epoxy resin of biomass heavy oil weight 6wt%, the polyethylene glycol 6000 that is the biomass heavy oil weight 12wt% after processing and the biomass heavy oil weight 1wt% after processing obtains mixture; Perform high-speed mixing at 80°C for 30 minutes to obtain biomass pitch.

[0023] The biomass pitch obtained above can be used to prepare asphalt shingle materials.

Embodiment 3

[0025] Treat the biomass heavy oil prepared from cotton stalks at a temperature of 110°C for 50 minutes (to remove moisture and small molecule volatiles), move the treated biomass heavy oil to a high-speed mixer, and then add the processed The epoxy resin of 3wt% weight of biomass heavy oil, the polyethylene (fresh or regenerated material) of 6wt% weight of biomass heavy oil after treatment and polyethylene glycol 6000 of 2wt% weight of biomass heavy oil after treatment are obtained Mixture: The obtained mixture was mixed at a high speed for 30 minutes at a temperature of 110° C. to obtain 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...
