specific Embodiment approach 1

[0017] Specific implementation mode 1: In this embodiment, the environment-friendly epoxy bio-asphalt material for road use is composed of 100 parts by mass of bio-asphalt, 35-60 parts of curing agent, 1-2 parts of strong alkali, 0.5-1 part of defoamer and 20 parts by mass. ~34 parts of epoxy resin, wherein the curing agent is an adduct of diethylenetriamine and butyl glycidyl ether.

[0018] In this embodiment, the high temperature performance and low temperature performance of the components are separated and different components are used to meet the requirements of material performance, and an epoxy bio-asphalt material with excellent high and low temperature performance, which can be quickly cured and used to repair key parts of the road is prepared. .

specific Embodiment approach 2

[0019] Embodiment 2: This embodiment is different from Embodiment 1 in that the strong base is granular or powdered sodium hydroxide or potassium hydroxide.

specific Embodiment approach 3

[0020] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the defoamer is a mineral oil defoamer.

Abstract

The invention relates to a highway environment-friendly epoxy biological asphalt material and a preparation method thereof, in particular to an epoxy biological asphalt material to repair a pavement and a preparation method thereof in order to solve the problem that existing biological asphalt materials have difficulty in balancing high- and low-temperature properties. The highway environment-friendly epoxy biological asphalt material is made from, by weight, 100 parts of biological asphalt, 35-60 parts of a curing agent, 1-2 parts of a strong base, 0.5-1 part of a defoaming agent, and 20-34 parts of epoxy resin. The preparation method includes: I, mixing the biological asphalt, the curing agent, the strong base and the defoaming agent to obtain biological asphalt mixture; II, mixing the epoxy resin with the biological asphalt mixture. The combination of the biological asphalt with the epoxy resin herein can balance the high- and low-temperature properties; the cured cross-linked epoxyresin is used to improve the high-temperature performance; the biological asphalt is used to fill the epoxy resin to provide toughening and to improve low-temperature performance; the curing time ofthe combination is well controlled, so that quick pavement repairing is achieved.

Description

technical field [0001] The invention relates to an epoxy bio-asphalt material applied to repairing road surfaces and a preparation method thereof, and in particular provides a composite epoxy compound epoxy resin, which adopts epoxy resin, curing agent and bio-asphalt to prepare high and low temperature performance and can quickly repair road surfaces. Bio-asphalt material and its preparation method. Background technique [0002] Bio-oil comes from a wide range of sources, including lignocellulosic materials such as crop stalks, rice husk sawdust, and tree bark. Bio-oil can be obtained through thermal cracking and other processes. In addition, biomass materials such as animal and vegetable oils are also included. It can be used to make biodiesel, and the remaining heavy oil can be used to make bioasphalt and be used in road paving. However, at present, most of the bio-asphalt used in road paving is only added to petroleum asphalt to replace part of petroleum asphalt, which...
