Description
Technical field
The invention discloses a kind of distress in concrete renovation agents, belong to technical field of polymer materials.
Background technology
Concrete structure is in civil engineering using a kind of most structures, construction casting is improper, reinforcing bar prepare it is very little,
Under the influence of many factors such as concrete shrinkage aging, load are overweight, concrete structure usually will appear crack.It deposits in crack
Steam, acid, alkaloid substance etc. can caused to penetrate into structure, causing steel bar corrosion, concrete stripping etc. to structure destructiveness
Damage, and influence bearing capacity and the service life of architectural appearance and concrete structure, thus need to these concrete
Structure carries out crack repairing work.Glued crack construction technology is one of method wherein to mend a split and most common side
Method.Glued crack technology be a kind of wider building of application reinforce with building reinforcing technology, by by the injection material of various ingredients
Material is configured to a kind of flowable slurry by the proportioning of design, and mechanical equipment is used in combination（Such as pump）Or other devices（Such as syringe）It will
It is pressed into the base material crack for needing reinforcing or leak stopping, so that slurries infiltrated, spread in base material crack, slurry then occurs
Chemical reaction, is solidified into solids.Slurry after solidification generates powerful firm bonding force to base material, whole as one with base material
Body achievees the purpose that reinforcing base material, raising load or room oozes leak stopping.Domestic epoxide resin grouting material is widely used in water conservancy project and builds
It builds and is reinforced with the anti-Seepage of crack in dam body；It is various mixed in the engineerings such as highway, bridge, subway, industry and civil buildings
The anti-Seepage consolidation process of solidifying soil cracking seam and basis.Crack repair materials used in early stage be using cement as key component,
Because of the advantages that its source is easy to get, cheap, simple process, it is widely used.
Crack repairing agent type currently on the market is more, can be divided into cement base class, third by its used adhesive material
Ketone-furfural class, unsaturated polyester (UP) class and EP（Epoxy resin）Class etc. can be divided into grouting material, grout material and pressure injection by application range
Glue etc..Wide seam can be perfused in grouting material containing aggregate；Grouting material without coarse aggregate is known as grout material, crack pouring width
For 1.5~5.0mm；Pressure injection glue is usually made of being modified EP Adhesives by low-viscosity, for closing and filling crack
Referred to as crack closure pressure injection glue, the referred to as crack reparation pressure injection of globality and partial intensities for restoring concrete component
Glue.
And traditional distress in concrete renovation agent is there is also the bad problem of mechanical property, to bringing in actual use
Inconvenience, therefore, so that distress in concrete renovation agent is played better performance becomes the art technology urgently to be resolved hurrily
One of problem.
Invention content
The present invention solves the technical problem of：Not for mechanical property existing for traditional distress in concrete renovation agent
The problem of good problem, provide a kind of distress in concrete renovation agent.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：
A kind of distress in concrete renovation agent, is made of the raw material of following parts by weight：
60~100 parts of epoxy resin
30~40 parts of curing agent
20~30 parts of diluent
10~20 parts of greasy filth
8~10 parts of plasticizer
20~30 parts of filler
3~5 parts of silane coupling agent
Modified 8~10 parts of additive
The preparation process of the distress in concrete renovation agent is：Each raw material is weighed by raw material composition, by epoxy resin, curing agent,
Diluent, greasy filth, plasticizer, filler, silane coupling agent and modified additive are stirred to get distress in concrete renovation agent.
The epoxy resin is any one in epoxy resin E51, epoxy resin E44 or epoxy resin E20.
The curing agent is ethylenediamine, and tetra-methylenedimine is arbitrary in hexamethylene diamine or ten dimethylene diamines
It is a kind of.
The diluent is any one in 660 n-butyl glycidyl ethers and 692 benzyl glycidyl ethers.
The plasticizer is two positive zinc ester of phthalic acid, in dibutyl phthalate or repefral
Any one.
The filler is zeolite, any one in medical stone or diatomite.
The silane coupling agent is silane resin acceptor kh-550, in silane coupling agent KH-560 or Silane coupling reagent KH-570
Any one.
The preparation process of the modified additive is：By rosin and ethanol solution in mass ratio 1：2~1：3 mixing, obtain No. 1
Mixed serum；It counts in parts by weight, by 5~8 parts of sepiolites, 10~20 parts of polyallylamines, 40~60 parts of water are stirred, and obtain 2
Number mixed serum, is counted, in parts by weight by 20~30 parts of No. 1 mixed serums, 20~30 parts of No. 2 mixed serums, 3~5 parts of carbonic acid
Hydrogen calcium constant temperature is stirred, Freezing smashing, crosses the sieve of 60 mesh to get modified additive.
The beneficial effects of the invention are as follows：
First, rosin is dispersed in ethanol solution in preparation process by the modified additive of addition by the present invention, then, will
Sepiolite, polyallylamine and water stirring, sepiolite are dispersed in polyallylamine aqueous solution, sepiolite fibre beam are formed, then by 1
Number mixed serum, No. 2 mixed serums and the mixing of calcium bicarbonate heating stirring, in the process, calcium bicarbonate is thermally decomposed, and is generated
The carbon dioxide of carbon dioxide and calcium carbonate, generation promotes polyallylamine to be crosslinked, and forms three-dimensional network so that sepiolite fibre beam
It is fixed in polyallylamine three-dimensional network with rosin, in use, polyallylamine cross-linked network is heated, internal titanium dioxide
Carbon starts to discharge so that polyallylamine three-dimensional network gradually starts solution crosslinking, and the mobility of system gets a promotion, internal fixed
Rosin and sepiolite fibre beam are released, and rosin molecule long-chain, which mutually tangles, forms thixotroping structure, then agitated, and winding is drawn
The effect of viscosity reduction is opened, meanwhile, rosin can carry sepiolite fibre beam and permeate and be distributed in original concrete and resin circle
At face, the interface cohesion of resin matrix and concrete is improved, to promote the mechanical property of system, in addition, containing pine in rosin
It is fragrant sour, a large amount of double bonds or carboxyl functional group are contained in rosin acid molecular structures, after being added in system, is had with concrete neutral and alkali
Machine Silica hydrogel reacts, to enhance the cohesive strength of system, to promote the mechanical property of system.
Specific implementation mode
The ethanol solution in mass ratio 1 for being 70~80% by rosin and mass fraction：2~1：3 are placed in No. 1 beaker, in turn
Under the conditions of speed is 300~500r/min, it is stirred 40~60min, obtains No. 1 mixed serum；It counts in parts by weight, by 5~8 parts
Sepiolite, 10~20 parts of polyallylamines, 40~60 parts of water are placed in No. 2 beakers, under the conditions of rotating speed is 400~600r/min,
It is stirred 40~60min, No. 2 mixed serums is obtained, counts in parts by weight, by 20~30 parts of No. 1 mixed serums, 20~30 part 2
Number mixed serum, 3~5 parts of calcium bicarbonates are placed in No. 3 beakers, and three-necked flask is placed in digital display and is tested the speed constant temperature blender with magnetic force
