Embodiment 1
[0030] An environmentally friendly, low-viscosity, high-strength epoxy-based chemical grouting material, comprising the following ingredients in parts by mass:
[0031]
[0032] The present invention selects the crosslinking diluent to replace the active diluent of the prior art such as furfural-acetone series and glycidyl ether at the cost of sacrificing the mechanical properties of grouting materials, and its components do not contain volatile materials such as formaldehyde and acetone, which are harmful to the human body. It is environmentally friendly and conforms to the concept of green development; and the viscosity of the initial slurry is low, the mechanical properties of the cured product are excellent, the proportion of the slurry is simple, easy to master, and the raw materials are easy to purchase and convenient for storage and transportation.
Embodiment 2
[0034] On the basis of embodiment 1, described epoxy resin is bisphenol A type epoxy resin, and bisphenol A type epoxy resin is E-35 type epoxy resin, E-44 type epoxy resin or E-51 One or at least two types of epoxy resins.
[0035] The crosslinking diluent is one or at least two of methyl methacrylate, butyl acrylate or hydroxybutyl acrylate.
[0036] The curing agent is one or at least two of diethylenetriamine, triethylenetetramine or tetraethylenepentamine.
[0037] The accelerator is one of N,N dimethylaniline, ethylimidazole or dimethylimidazole.
[0038] The initiator is obtained by mixing peroxide and an inert solvent according to the mass ratio (50-80): (20-50), standing still for 24 hours, and then fully dehydrating.
[0039] Described peroxide is one or at least two in organic peroxide; Described peroxide is more preferably benzoyl peroxide, cyclohexanone peroxide, dilauroyl peroxide, tertiary peroxide One or at least two of butyl esters.
[0040] The inert solu...
Embodiment 3
[0046] The proportioning of each component in the present embodiment is:
[0047] Liquid A: 75 parts by mass of E-51 type epoxy resin and 25 parts by mass of methyl methacrylate are uniformly mixed to obtain;
[0048] Liquid B: obtained by uniformly mixing 10 parts by mass of diethylenetriamine and 4 parts by mass of N,N dimethylaniline;
[0049] Preparation of liquid C: 65 parts by mass of benzoyl peroxide and 50 parts by mass of dibutyl phthalate were uniformly mixed, and after standing for 24 hours, fully dehydrated to obtain an initiator.
[0050] When in use, mix liquid A, liquid B and 8 parts by mass of liquid C to obtain an environmentally friendly, low-viscosity, high-strength epoxy-based chemical grouting material.
