Description
Technical field
The present invention relates to macromolecule building material technical field, and in particular to a kind of to subtract for the high-strength of large equipment base
Shake epoxy resin mortar and preparation method thereof.
Background technology
Because epoxy resin mortar has the performances such as Self-leveling, quick solidifying, intensity height, strong, the corrosion-resistant, waterproof of cohesive force, in stone
Oily petrochemical industry is often used as the back-grouting material of the larger vibration equipment Foundations such as compressor.But the epoxy resin mortar for using at present
Formula is mostly around stocks such as epoxy resin, cement, sand, amine curing agents, it is difficult to pass through simply to adjust proportioning raw materials
So as to reach higher toughness and intensity, to adapt to the requirement of Specific construction environment.
Epoxy resin is to refer to the organic high molecular compound containing two or more epoxide groups in molecule, except individual
Not outer, their relative molecular mass is not high.The molecular structure of epoxy resin is to contain active epoxy radicals in strand
Group is its feature, and epoxide group may be located at the end of strand, middle or circlewise structure.Live due to containing in molecular structure
Bold and vigorous epoxide group, makes them to crosslink reaction with polytype firming agent and be formed insoluble, insoluble with three-dimensional
Cancellated high polymer.
The patent of invention of Publication No. CN101423358A discloses a kind of preparation method of high impact resistant epoxy resin mortar, the system
The raw material of component A includes polyurethane modified epoxy resin, quartz sand, diluent, plasticizer in Preparation Method, and quartz sand is by granule
The coarse sand and particle diameter of a diameter of 0.5-3mm is mixed by a certain percentage in the fine sand of 80-400 mesh, the raw material bag of B component
Include room temperature amine curing agent, quartz sand, diluent.Although solidfied material obtained in the invention has good resistance to compression, shearing resistance and anti-impact
Hit intensity, but still have following defect：The coarse sand selected in the invention and the grain diameter of fine sand differ greatly, particularly coarse sand,
Its particle diameter has reached 0.5-3mm, and obtained epoxy resin mortar is not easy to apply smooth in work progress, and bonding base material is to quartz sand
Covered effect is poor, so as to affect the etch resistant properties of epoxy resin mortar；Invention is with diethylenetriamine, triethylene tetramine or low-molecular-weight
Used as firming agent, the use of such firming agent can cause curing reaction wayward because of excessive velocities to polyamide, so as to applying
Work is made troubles.
The patent of invention of Publication No. CN103482904A discloses a kind of modified epoxy mortar abrasion-resistant patching material, should
Invention overcomes the excessive impact etch resistant properties of aggregate size present in patent CN101423358A technology, curing reaction excessive velocities
Problem, there is provided a kind of aggregate size it is moderate and can effectively reduce curing reaction speed modified epoxy mortar resistant abrasion repair
Material；But while the anti-impact mould intensity of epoxy resin mortar and impact strength are improved, its damping intensity decreases.
In addition, often because manual stirring method is improper to produce a large amount of bubbles, bubble in solidification process in work progress
Resin matrix cannot be rapidly separated so that mortar fragility itself becomes big, intensity step-down after solidification, or even large area hollowing and mixed
Solidifying earth foundation is peeled off, it is impossible to is repaired, can only be done over again.
