Description
The present invention relates to a kind of modified furfural-acetone epoxy as reinforcing, concreting and grouting material and preparation method thereof.
Polymeric grouting materials is some to be contained polyfunctional compound or oligopolymer and initiator or solidifying agent, catalyzer, thinner, properties-correcting agent etc. be mixed with slurries, inject the building structure part of required processing with certain technology, generate macromolecular material through chemical reaction, reach purpose with being combined the reinforcing or the impervious leakage-stopping of structure by the filling medium-tight.
Polymeric grouting materials is to develop rapidly the sixties, has been widely used in the fissured reinforcing of water power dam, underground works, port and pier and buildings; Aspects such as the antiseepage processing in mine, oil well, tunnel and historical relic's protection.Polymeric grouting materials has developed into up to a hundred kinds such as acrylamide, furfuralacetone expoxy resin, methyl acrylic ester, lignin at present.
Furfuralacetone expoxy resin major technique characteristics are: grouting liquid viscosity and setting time are adjustable, the concretion body strength height, and bonding force is strong.It is when being applied to the reinforcement and consolidation of defectives such as concrete or rock micro-cracks, and effect is better.Yet in various civil construction projects, usually exist some to uphold construction joint, expansion joint and the various crack bigger with contraction with the cold and hot variation of four seasons weather, common materials such as furfuralacetone expoxy resin are difficult to satisfy relevant application performance requirement, therefore, this just needs a kind of have more snappiness, elongation, and with concrete the novel injection material of good bonding strength is arranged.
The furfuralacetone expoxy resin grouting material that the purpose of this invention is to provide a kind of modification, thereby the problem in the application of solution furfuralacetone expoxy resin grouting material.Compare with the furfuralacetone expoxy resin grouting material of present use, this material also has higher elongation on the basis that keeps original injection material basic fundamental performance, technical characterstics such as better thermotolerance.
Another object of the present invention provides the preparation method of this modified furfural acetone epoxy grouting material.
The invention provides a kind of organic-silicon-modified furfural-acetone epoxy as reinforcing, concreting and grouting material, comprise organosilicon modified furfural acetone epoxy component (A) and solidifying agent component (B).Component (A) is counted by weight, comprising:
100 parts of bisphenol A type epoxy resins,
0.5～35 part of amido silicon oil,
3～150 parts in furfural
1～50 part in acetone;
Inorganic strong alkali is a small amount of
Solidifying agent component (B) is a polyamine;
Component (A) is 100: 7～85 with the weight proportion of component (B).
Organic-silicon-modified furfural-acetone epoxy as reinforcing, concreting and grouting material preparation method of the present invention may further comprise the steps:
A, with furfural and acetone according to described mixed, on one side vigorous stirring, drip dense inorganic strong alkali solution on one side, be the boiling shape up to solution.Primitive reaction is as follows: condensation reaction takes place in furfural and acetone under the effect of basic catalyst, dries out to generate a furfural acetone and two furfural acetones:
One furfural acetone couples together by carbonyl and the further condensation of methyl in the presence of catalyzer, generates the polymer with following structure:
Two furfural acetones are then crosslinked by opening two keys.
B, amido silicon oil is joined in the Resins, epoxy 100～130 ℃ of reactions 2～3 hours down in described ratio.Primitive reaction is as follows:
R is an alkyl.
C, step a and b products therefrom are mixed, stirred under the room temperature 10～20 minutes, component (A).
D, component (A) and component (B) is even by described mixed.
The consumption of amido silicon oil is preferred 10～25 parts in this organic-silicon-modified furfural-acetone epoxy as reinforcing, concreting and grouting material, preferred 15～80 parts of furfural, preferred 5～30 parts of acetone.
Wherein bisphenol A type epoxy resin is the Resins, epoxy commonly used in the furfural-acetone epoxy as reinforcing, concreting and grouting material, and the oxirane value of bisphenol A type epoxy resin is generally 0.04～0.6g/100g, preferred 0.15～0.56g/100g among the present invention.
Polyamine is a polyamine commonly used in the furfural-acetone epoxy as reinforcing, concreting and grouting material, can be selected from aliphatic polyamine, polymeric amide polyamine, alicyclic polyamine, aromatic polyamine and their modifier, as diethylenetriamine, quadrol, isophorone diamine, mphenylenediamine, m-xylene diamine, polymeric amide etc.
Inorganic strong alkali plays katalysis in furfural and condensation of acetone reaction, be known in the art, can adopt sodium hydroxide, potassium hydroxide etc. usually.
Amido silicon oil is a kind of silicone oil of aminoalkyl modification, can regard the product after part methyl in the dimethyl silicone oil (comprising side position and end position) is replaced by the ammonia alkyl as, comprises end group type, pendant type, end to side fundamental mode amido silicon oil.Generally selecting viscosity for use is 5～50Pas, and amino content is the amido silicon oil of 0.2～1.2 (wt) %, and preferred viscosities is 10～30Pas, and amino content is 0.5～1.0 (wt) %.
In order further to improve the performance of material, wherein can add some softening agent etc., as the dioctyl phthalate (DOP) of 5～60 parts of interpolations in the component (A) of material, this dioctyl phthalate (DOP) can be selected from phthalic acid n-octyl, dimixo-octyl phthalate and their mixture.These materials can add in any step for preparing as required.
Organosilicon macromolecule is because its particular structure, the valuable performance so have many uniquenesses.At first, its main chain Si-O bond energy is big, so it has good heat endurance, resistance to oxidation, weathering resistance.Secondly, the side group majority of organosilicon macromolecule is a methyl, so its Intermolecular Forces is little, surface energy is low.The 3rd, its main chain Si-O bond distance is about C-C bond distance's sesqui, and molecule is the shape structure in the shape of a spiral, can rotate freely, so its cold property energy is good, rate of compression is bigger.
Organic-silicon-modified furfural-acetone epoxy as reinforcing, concreting and grouting material of the present invention can prepare component (A) and component (B) respectively and encapsulate in advance, can use after proportionally mixing when treating practice of construction again.
The organosilicon macromolecule that the present invention will have special performance is incorporated in the Resins, epoxy, thereby has solved the problem in the application of furfural acetone epoxy grouting material, and a kind of high-performance furfural acetone epoxy grouting material is provided.Compare with the furfuralacetone expoxy resin grouting material of present use, this material also has higher elongation on the basis that keeps original injection material basic fundamental performance, technical characterstics such as better thermotolerance.
