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 the acid-fast alkali-proof corrosive environment being implemented protection.
[background technology]
Need the occasion of erosion resistance for civil construction, engineering field, generally use thermosetting resin to be base mateiral floor construction worker method.This construction method requires thermosetting resin that superior corrosion resistance is arranged, and has normal temperature solidifiedly, and application property is good, the characteristics that set time is short etc.Generally the thermosetting resin as floor construction mainly contains: 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 technology of the domestic comparative maturity of doing all adopts unsaturated polyester resin or epoxy resin now, by typical metaphenylene or bisphenol A-type unsaturated polyester resin, relatively their chemical constitution; Can see that carboxyl and the dual unsaturated group of hydroxyl are all arranged at their molecular structure two ends, all have dual or multiple ester group to circulate repeatedly in the main chain; The existence of these groups all greatly reduces the anti-hydrolytic performance of resin, and with regard to epoxy resin, because when ambient cure; Adopt the solidifying agent of amine; And the solidifying agent of amine self is alkaline, thus its alkali resistance than more excellent, and acid resistance is just poor.Because China starts late at the resin corrosion-resistant field; Though the construction of using vinyl ester resin to do anticorrosion terrace at present also is in the starting stage; But because vinyl ester resin has perfect corrosion resistance nature, it will strengthen in anticorrosion terrace Application for Field status greatly.
Use vinyl ester resin to have multiple as the construction method of base material; But the service condition of returning its material can be divided into two types; One type is that the resin that from the primary coat to the face, is coated with all uses vinyl ester resin, another kind of in whole operation resin partly 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 higher relatively; The latter adopts suitable compound construction technology, can take into account the cost of bonding force, acid-proof alkali prevention performance and the material of terrace effectively comprehensively.
[summary of the invention]
The objective of the invention is to overcome defective of the prior art, provide that bonding strength is good, short construction period and have thermosetting resin that the terrace of extremely excellent acid-fast alkali-proof performance uses and the constructional method of terrace.
To achieve these goals; The present invention designs a kind of thermosetting resin that is used for the acid-proof anti-alkali floor, it is characterized in that described thermosetting resin is epoxy resin or radical polymerization-type resin, and described radical polymerization-type resin is unsaturated polyester resin or vinyl ester resin or gathers in (methyl) acrylic amide resin one or more; The degree of unsaturation of described radical polymerization-type resin is 100 ~ 800; Also add in the thermosetting resin of per 100 weight parts, reaction diluent 10 ~ 250 weight parts, preferred amounts is 20 ~ 100 weight parts; Organo-peroxide 0.1 ~ 7 weight part, preferred 0.5 ~ 5 weight part.

G. refer to touch do after, the coated face coating, described finishing coat is to be mixed and made into according to mill base, 5 parts of liquid waxes of adding 10 parts in the thermosetting resin of per 100 weight parts.
When the thermosetting resin that is coated with among the step b is epoxy resin, on described epoxy resin layer, also be coated with one deck one fluid polyurethane resin.
Among the step b, in described primary coat, also be coated with one deck packing layer, add 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 described packing layer according to per 100 weight parts.
Described molecular sieve thinner is vinyl methoxy silane, vinyl triethoxyl silicomethane, vinyl three (2-2 methoxy ethoxy) silane.
When thermosetting resin adopted epoxy resin, putty obtained according to per 100 parts by weight resin interpolation Witcizer 300 5-15 weight part, acetone 10-30 weight part, the mixing of silica sand 100-300 weight part,
When thermosetting resin adopted described radical polymerization-type resin, putty obtained according to per 100 parts by weight resin interpolation vinylbenzene, 0.2 ~ 5 weight part, the mixing of silica powder 50-300 weight part.
In the steps d, paste two-layer alkali-free glass fiber or the organic fiberglass layer of pasting.
A fluid polyurethane resin that uses among the present invention; It is the doubling body that vulcabond and the organism that contains 2 above reactive hydrogen atoms react the main body of the urethane that obtains; Because contain the free NCO; Receive the effect of heat or catalyst; NCO itself reacts or reactions such as NCO and water, glycol become the record that this kind resin is arranged in the heat reactive resin " plastics industry dictionary " (census of manufacturing meeting, distribution in 1985); In more detail, the prepolymer of terminal isocyanate and the moisture in the atmosphere react prepolymer that is solidified into humid solidified type (a liquid type) or terminal isocyanate and the heat reactive resin that the moisture in the soil reacts and becomes, as the anti-water seal that is used for native sand ends urethane that the civil construction of material etc. uses, polyurethane adhesive, polyurethane coating etc.Also can utilize other material known to be cured.The organic cpds and the many compounds of NCO mole ratio hydroxyl that contain 2 above hydroxyls like end react, and 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 that is similar in the vinylbenzene in the solvent is then better.
Among the present invention, in the time of necessary, for the phenomenon that prevents to flake at moistening concrete surface; Add packing layer with known method and give its thixotropy, the cementability of coating is strengthened, as; Add silane coupling agent, as adding 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, can use together with the thinner of molecular sieve etc. in the time of necessary, like 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.Among the present invention,, in the time of necessary, do not influencing under the solidified situation, can add the organic and inorganic staple fibre of mineral filler, organic filler, number mm in order to solve the expansion that causes primary coat owing to the vapour pressure of the water vapour of inside concrete.
The present invention compares with prior art; From specifically being to learn in the contrast form the embodiment; 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, the dihydroxyphenyl propane structure that excellent mechanical property is provided is arranged in the molecular backbone chain, and ester group only occurs at the two ends of molecular chain also; And receive the protection of methyl; Therefore it has extremely excellent corrosion resistance nature, and molecular end has the existence of methylpropenyl, has guaranteed the same outstanding curing performance of it and common unsaturated polyester resin.Also the elapsed time proves simultaneously, and vinyl ester resin has best corrosion resistance nature at present.The occasion that a lot of epoxy resin can not be suitable for all can adopt vinyl ester resin to substitute.
