Description
Technical field
The invention belongs to the Techniques of Relics Protection field, particularly relate to a kind of liquid water rigid native ruins reinforcement material and reinforcement means.
Background technology
The soil ruins be produce specific period of carrying over of ancients, the traces of life, carrying important history culture information, research has significant values for ancient culture.But, because the singularity of soil, the accumulation of salt in the surface soil as usual, easy-weathering is met water disintegration and biology and is grown etc., and native ruins are to cannot say for sure one of historical relic that protects most.Because lack effective protecting materials and technology, many important native ruins rapidly disappear, such as some locations, ancient city of NORTHWEST CHINA, ancient Great Wall and beacon flint; More southern soil make up builds traces etc.
At present, the method for native ruins protection is broadly divided into two classes: in-situ conservation and allopatric protection.Allopatric protection is applicable to the protection in small-sized ruins, but can isolate getting in touch of ruins and environment of living in unavoidably in the transition process of ruins, loses the important historical cultural information.In-situ conservation is easy to be subjected to the destruction of local environment factor, needs to use suitable protecting materials to reinforce and protect, but the subject matter that faces at present is to lack effective reinforcement material, especially for the large-scale native ruins in China's south wet environment.Native ruins chemical consolidation material commonly used has following several: (1) inorganic materials, comprise water glass, calcium hydroxide, hydrated barta etc., and wherein use comparatively extensive with water glass class material again.For example: CN1693588A has announced a kind of method with high-module potassium silicate compacted soil ruins.It is better to experiment showed, that this class material is used for the consolidation effect in arid area soil ruins, but when using in the humid area, reinforcing and waterproof effect are all not obvious.ZL200510050877.2 has announced a kind of method of using methyl silicate compacted soil ruins, and water-repellancy is better than with the reinforcement material of water glass as host when wet environment uses, but limited to the depth of penetration in native ruins.(2) organic materials is as organic silicone resin, PFPE, polypropylene acid etc.For example: ZL200310108663.7 has announced that a kind of is organic tripoli ruins reinforcement material of solvent with the ethyl acetate.CN1840551A has announced a kind of acrylate-organosilicon-epoxide resin reinforcement material.CN1912316A has announced also that with silicon third or fluorine silicon resin high-molecular cement etc. are used for native ruins and reinforce so that move the method for allopatric protection.This class reinforcement material has fastening strength preferably by the network structure of crosslinking reaction generation based on organic substance.But, the consistency of the organism material and the soil body itself is often bad, flakes easily, and some also can produce at wet environment goes mouldy, and influences the outward appearance of historical relic; The organic in addition life-span is always very limited.(3) cement class reinforcement material, cement has good fastening strength, but contains a large amount of salt in the cement, and alkalescence is too strong; And when using is body of paste, can't penetration reinforcement, and it can not be directly used in the reinforcement protection in native ruins these characteristics decisions.
Summary of the invention
The purpose of this invention is to provide the rigid inorganic coagulation material of a kind of liquid water that meets the historical relic's protection requirement, in the hope of infiltration better with combine, for the reinforcing of open-air earth site surface layer provides new material and method with the soil body.Reinforcement material raw material provided by the invention is easy to get, the preparation condition gentleness, and using method is simple and convenient, and consolidation effect is obvious, and soaking-resistant is good with soil body consistency, non-environmental-pollution
The rigid native ruins of liquid water provided by the invention reinforcement material is that compound, active silica, alcoholic solvent and the tensio-active agent with calcium is mixed with calcium source solution and silicon source solution; The compound of described calcium is a calcium oxide, calcium hydroxide, and the salt of weak acid of calcium; Described active silica is alkali-metal silicate, amorphous silica, and silicon sol; Described alcoholic solvent is rudimentary dibasic alcohol or rudimentary monobasic saturated alcohol; Described calcium source solution is the compound preparation of rudimentary dibasic alcohol solubilize calcium; Described silicon source solution is alkali metal silicate aqueous solution, the colloidal solution of perhaps rudimentary monobasic saturated alcohol and amorphous silica or silicon sol preparation; The mass ratio of described calcium source solution and silicon source solution is 1: 1～4: 1; Described tensio-active agent is one or more of calcium lignin sulphonate, methylene-disulfonic acid sodium, alkylphenol polyoxyethylene compounds.
The compound of calcium is among the present invention: calcium oxide, calcium hydroxide, and the salt of weak acid of calcium are as calcium acetate, citrate of lime, caoxalate etc.Be good wherein with calcium oxide and calcium hydroxide.
Active silica among the present invention is: alkali-metal silicate, as potassium silicate, water glass etc.; Amorphous silica is as nanometer grade silica particles such as the white carbon blacks of gas phase; And silicon sol.Above-mentioned alkalimetal silicate is the aqueous solution, and the modulus scope is 3.0～4.2, is preferably 3.8～4.0; The amorphous silica grain diameter requires less than 100nm; Silicon sol is commodity in use level ethanol silicon sol directly.
Alcoholic solvent among the present invention is: rudimentary dibasic alcohol, as ethylene glycol, propylene glycol etc.; And rudimentary monobasic saturated alcohol, as ethanol, propyl alcohol etc.Above-mentioned rudimentary dibasic alcohol is used to prepare calcium source solution, and dibasic alcohol far above water, is good from the amount and the evaporation rate comparison of solubilize calcium with ethylene glycol to the solubleness of the compound of calcium.Above-mentioned rudimentary monobasic saturated alcohol is used for prepare silicon source solution, and with lytic activity silicon-dioxide, rudimentary monobasic saturated alcohol good penetrability, volatilization comparatively fast consider with ethanol to be good from the environmental protection factor.Lower alcohols solvent and water section dissolve each other, and the bulking of soil is less than water, and perviousness are better than water, soil body easy disintegrating not when penetration reinforcement, and can reach the effect that deep layer is reinforced.
Tensio-active agent among the present invention is: calcium lignin sulphonate, methylene-disulfonic acid sodium, OP-10 (alkylphenol polyoxyethylene compounds) etc., can use one or more collocation, and consumption is 0.01%～1.0%.Above-mentioned tensio-active agent is mainly used in and strengthens infiltration, wetting and filling effect.
Calcium source solution described in the present invention be compound dissolution with calcium in rudimentary diol solvent, be prepared into the glycol solution of calcium.Because the solubleness of calcium is very limited, except that Special Circumstances, calcium source strength of solution is good with the saturated solution of calcium generally.When the needs percdation, can reduce the viscosity of calcium source solution by the concentration of suitable reduction calcium, thereby improve osmotic effect the soil body.
Silicon source solution described in the present invention is solution or the colloidal solution that contains active silica, two kinds of type of solvent is arranged: the aqueous solution of first alkalimetal silicate; It two is colloidal solutions of the rudimentary monobasic saturated alcohol of amorphous silica or silicon sol.The mass concentration of above-mentioned alkali metal silicate aqueous solution is 1～8%, is preferably 2%～5%; The mass concentration of the colloidal solution of the rudimentary monobasic saturated alcohol of above-mentioned amorphous silica or silicon sol is 1～5%, is preferably 2～3%.
In the reinforcing process of native ruins, when using above-mentioned alkali metal silicate aqueous solution as silicon source solution, silicon source solution and calcium source solution must permeate respectively, form precipitation to avoid active silica and calcium constituent to react before infiltration.Successively be 0.1～6 hour pitch time, can replace repeatedly infiltration in order to improve the amount of infiltrating solute in the soil body.When the alcoholic solution that uses above-mentioned amorphous silica or silicon sol during as silicon source solution, silicon source solution and calcium source solution can be permeated respectively, also can mix again earlier and permeate.Since in the mixing solutions water-content seldom, organic molecule has intercepted the reaction process of active silica and calcium constituent, mixes earlier and permeates the uniform mixing that helps two kinds of solution again.The mass ratio of the usage quantity of calcium source solution and silicon source solution was good with 1: 1～4: 1 in the present invention.
The hydraulicity of the present invention reaction be above-mentioned calcium source solution and silicon source solution permeate finish after, on the soil body penetration face, spray deionized water, perhaps rely on the humidity in the soil body that the water source is provided,, cause hydraulicity reaction lentamente with the alcoholic solvent in the water substitution reinforcement material.The usage quantity of water is decided on the water ratio of the soil body itself and the moisturizing situation of environment, can be suitably excessive.Under the effect of water, in the reinforcement material compound of calcium can with the activeconstituents in active silica and the soil, hydraulicity reaction takes place as aluminium sesquioxide and soluble silicate etc., generate the glued composition of the hydraulicity, as Calucium Silicate powder, calcium aluminate etc.; The compound of the calcium that can react Wan then is gradually transformed into insoluble calcium salts such as lime carbonate under the effect of water and air.The cementing power of Calucium Silicate powder is very strong, soaking-resistant and washing away, and it is the main ingredient that cement solidification forms intensity; The insoluble calcium salts such as lime carbonate itself that generate are not water funk, to what soil layer also had good consolidation force arranged.
The rigid native ruins of liquid water of the present invention reinforcement material has following advantage:
