example 1

[0015] Example 1: Epoxy resin (87 parts) and ethylene glycol diglycidyl ether (13 parts) are mixed uniformly under the stirring of a conventional mixer, and then reacted with 15% polyethanol-based (PEG) unit polyether amine to prepare into a non-emulsifying hydrophilic epoxy resin.

example 2

[0016] Example 2: Mix the hydrophilic epoxy resin aqueous solution (13 parts) with a solid content of 60% into the emulsified asphalt (87 parts) with a solid content of 60%, and stir it fully with a conventional mixer until it becomes a uniform emulsion. It can be seen that the polymer particles can be used to prepare thermosetting epoxy resin modified emulsified asphalt.

example 3

[0017] Example 3: Epoxy resin with a hydrophilic content of 13%, thermosetting epoxy resin modified emulsified asphalt with a solid content of 60% (100 parts), and a thermosetting epoxy resin curing agent with a solid content of 60% ( 7 parts) mixed and cross-linked, after curing, it is polymerized into a thermosetting epoxy resin modified asphalt polymer.

[0018] In the above-mentioned preparation and reaction process, all are carried out under normal temperature and normal pressure. If possible, in the manufacturing process of hydrophilic epoxy resin and epoxy resin curing agent, the reaction temperature is controlled between 60°C and 80°C, which can speed up and control the reaction speed, reduce the reaction time and improve the reaction quality.

Abstract

The invention relates to the technical field of engineering construction, in particular relating to thermosetting epoxy resin modified emulsified asphalts. The epoxy resins with the epoxide value of 0.38eq / 100g-0.54eq / 100g is diluted by a hydrophilic epoxy resin reactive diluent, namely ethylene glycol diglycidylether, and is reacted with unit polyether amine of hydrophilic polyethylene glycol (PEG) to prepare into non-emulsified hydrophilic epoxy resins, and the aqueous solution of the non-emulsified hydrophilic epoxy resins is mixed with the emulsified asphalts. Because the thermosetting hydrophilic epoxy resins do not contain an emulsifier so as to have no residuals and discharge of emulsifier toxicity, the thermosetting hydrophilic epoxy resins are environment-friendly, can be stored for a long time under the waterless condition, and are convenient to transport and store. The thermosetting hydrophilic epoxy resins have good compatibility for the emulsified asphalts, good modification effect, and can cause the emulsified asphalts which are not modified to begin to dissolve at the temperature of 60 DEG C so as to be converted into the emulsified asphalts which have the characteristic of being not dissolved at the temperature of 160 DEG C.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a thermosetting epoxy resin modification that can be widely used in waterproofing, bonding, filling joints, stress-absorbing layers of asphalt concrete pouring overlays, etc. for highways, bridges, and building foundations. emulsified asphalt. Background technique [0002] Since the existence of human civilization, the road has been extending infinitely under people's feet. From the rough trails stepped on by people to the sidewalks paved with cobblestones, from the concrete poured on the cement pavement to the asphalt pavement widely used today, it proves the development history of human civilization from one side. [0003] We know that the asphalt pavement that is widely used today has the advantages of good wear resistance, no dust, and good braking performance of motor vehicles. However, it also has the disadvantages of low melting point and poor low temper...
