Description
[technical field]
The present invention relates to a kind of composite anti-corrosion erosion terrace and new construction method thereof of simultaneously buildings terrace under acid-fast alkali-proof corrosive environment being implemented protection.
[background technology]
For civil construction, engineering field, need the occasion of erosion resistance, generally use thermosetting resin for base mateiral floor construction engineering method.This construction method requires thermosetting resin to have good erosion resistance, has normal temperature solidifiedly, and application property is good, set time short grade feature.Generally as the thermosetting resin of floor construction, mainly contain: epoxy resin, O-phthalic acid type unsaturated polyester, bisphenol A-type unsaturated polyester, chlorine bridge (Hai Te) acid type unsaturated polyester, vinyl ester resin etc.The terrace technique of the domestic comparative maturity doing all adopts unsaturated polyester resin or epoxy resin now, by typical metaphenylene or Bisphenol a unsaturated polyester resin, relatively their chemical constitution, can see, at their molecular structure two ends, all there are carboxyl and the dual unsaturated group of hydroxyl, in main chain, all there is dual or multiple ester group iterative cycles, the existence of these groups all greatly reduces the anti-hydrolytic performance of resin, and with regard to epoxy resin, due to when the ambient cure, adopt the solidifying agent of amine, and the solidifying agent of amine self is alkaline, so its alkali resistance is than more excellent, and acid resistance is just poor.Because China starts late at resin corrosion-resistant field, although the construction of doing anticorrosion terrace with vinyl ester resin is at present also in the starting stage, but because vinyl ester resin has perfect corrosion resistance nature, its application status in anticorrosion terrace field will strengthen greatly.
Use vinyl ester resin to have multiple as the construction method of base material, but return the service condition of its material can be divided into two classes, one class be from primary coat to face be coated with resin all use vinyl ester resin, another kind of in whole operation resin part use vinyl ester resin.The former advantage is the acid-fast alkali-proof performance that can provide enough good, but its shortcoming is the bonding force that does not have epoxy resin equally good, and material cost is relatively high; The latter adopts suitable compound construction technology, can effectively take into account the cost of bonding force, acid-proof alkali prevention performance and the material of terrace comprehensively.
[summary of the invention]
The object of the invention is to overcome defect of the prior art, provide that bonding strength is good, short construction period and there is thermosetting resin that the terrace of extremely excellent acid-fast alkali-proof performance uses and the constructional method of terrace.

When the thermosetting resin being coated with in step b is epoxy resin, on described epoxy resin layer, be also coated with one deck one fluid polyurethane resin.
In step b, be also coated with one deck packing layer in described primary coat, described packing layer is according to adding the silane coupling agent of 0.1 ~ 50 weight part and/or the molecular sieve thinner of 0.1 ~ 20 weight part in the thermosetting resin of every 100 weight parts.
Described molecular sieve thinner is vinyl methoxy silane, vinyl triethoxyl silicomethane, vinyl three (2-2 methoxy ethoxy) silane.
When thermosetting resin adopts epoxy resin, putty is mixed to get according to every 100 parts by weight resin interpolation dibutyl phthalate 5-15 weight parts, acetone 10-30 weight part, quartz sand 100-300 weight part,
When thermosetting resin adopts described radical polymerization-type resin, putty is mixed to get according to every 100 parts by weight resin interpolation vinylbenzene 0.2 ~ 5 weight parts, silica powder 50-300 weight part.
In steps d, paste two-layer alkali-free glass fiber or the organic fiberglass layer of pasting.
The fluid polyurethane resin using in the present invention, it is the doubling body that vulcabond and the organism that contains more than 2 reactive hydrogen atom react the main body of the urethane obtaining, because contain free isocyanate group, be subject to the effect of heat or catalyst, isocyanate group itself reacts or isocyanate group and water, the reactions such as glycol become heat reactive resin < < plastics industry dictionary > > (census of manufacturing meeting, distribution in 1985) in have the record of this kind of resin, in more detail, moisture in prepolymer and the atmosphere of terminal isocyanate reacts and is solidified into moisture in prepolymer and the soil of humid solidified type (a liquid type) or the terminal isocyanate heat reactive resin becoming that reacts, the urethane of using as the civil construction of waterproof sealing material for native sand etc., polyurethane adhesive, polyurethane coating etc.Also can utilize other known material to be cured.As organic compound and the many compound reactions of isocyanate group mole ratio hydroxyl that end contains more than 2 hydroxyl, also can contain solvent.Corresponding product but be not limited to: Ha イ セ Le OH series (eastern nation chemical industry (strain) system), ADEKAA-50, ADEKAA-80(rising sun electrochemical industry (strain) system), Water magic (Reoization is ground (strain) and made) etc.The compound that contains the repeatability unsaturated group being similar in vinylbenzene in solvent is better.
In the present invention, in the time of necessary, for the phenomenon that prevents from flaking at moistening concrete surface, by known method, add packing layer and give its thixotropy, the cementability of coating is strengthened, as, add silane coupling agent, as add but be not limited to: silica flour, mica powder, calcium carbonate powder etc.Press resin 100 weight parts, the method for adding 0.1 ~ 50 weight part adds.About silane coupling agent, in the time of necessary, can use together with the thinner of molecular sieve etc., as vinyl methoxy silane, vinyl triethoxyl silicomethane, vinyl three (2-2 methoxy ethoxy) silane etc.Press resin 100 weight parts, add 0.1 ~ 20 weight part and add.In the present invention, in order to solve the expansion that causes primary coat due to the vapour pressure of the water vapour of inside concrete, in the time of necessary, do not affecting curing in the situation that, can add the organic and inorganic staple fibre of mineral filler, organic filler, number mm.
The present invention compared with the existing technology, in contrast form from embodiment specifically, can learn, the product that this religious name has adopted new technical recipe and constructional method to obtain has better transaction capabilities, resistance alkaline resistance properties, solvent resistance, oxidation resistent susceptibility and low-temperature curing performance, and its construction period is also shorter.
In the present invention; with typical bisphenol A-type vinyl ester resin for example; in molecular backbone chain, have the dihydroxyphenyl propane of excellent mechanical property structure is provided; and ester group also only occurs at the two ends of molecular chain; and be subject to the protection of methyl; therefore it has extremely excellent corrosion resistance nature, and molecular end has the existence of methylpropenyl, has guaranteed it and common unsaturated polyester resin outstanding curing performance equally.Also the elapsed time proves simultaneously, and vinyl ester resin has best corrosion resistance nature at present.The occasion that much epoxy resin can not be applicable, all can adopt vinyl ester resin to substitute.
