Description
Technical field
The present invention relates to a kind of surfacecti proteon nano paint, particularly relate to a kind of stone surface protection nano coating and manufacture craft thereof.
Background technology
In building trade, stone material is most widely used material of construction, the various decorative stone the most generally used from the rock cave in ancient times, stone bridge, pinnacle, Shi Ting to the modern times and various cliff painting, statue, wall are carved and monument etc., stone material is with its firm quality, and the striped of beautiful colorful tone and magical change is applied more and more widely.Be that the buildings of material of construction and decoration has beautified the living environment of people with stone material, people are fully experienced natural beauty and glamour.The surface of stone material can be divided into polished face and open grain surface.The stone material on that a kind of surface because stone material is made up of multi mineral, very easily reacts with other chemical substances, so all can be polluted and corrode.Want preventing treatment stone material to be polluted and corrode, first will understand stone material illness and how to produce.
1.1 the accumulation of salt in the surface soil
Stone surface after wet construction or stone material seam crossing, can produce the mixture of one deck white alkali and salt in routine use, this phenomenon is called the accumulation of salt in the surface soil.The reason of the accumulation of salt in the surface soil is: sand-cement slurry and water, carbonic acid gas generation chemical reaction, produce the aqueous solution containing alkali and salt, stone surface is penetrated into by hole, after water evaporates, alkali and salt become white crystals body, are attached to stone surface, and the lighter forms white dot, serious meeting destroys stone surface gloss, affects decorative effect.
1.2 rust staining
Band color substance can be generated under the metal ion of stone surface or inside and water, oxygen effect, remain in stone surface, form rust staining.The Crack cause of rust staining has two aspects: one is that natural reaction is formed; because containing rhombohedral iron ore or sulfurous iron ore in the material composition of stone material inside; these materials are oxidized to the band color substances such as ferric oxide after touching water, air, the hole through stone material oozes out, and form rust staining; Two is that stone material contacts iron compound in the processes such as exploitation, processing, transport, and these irony materials remain in stone surface, after by water, atmospheric oxidation, form rust staining.
1.3 water stain
After stone material contacts with sand-cement slurry, the alkaline matter in sand-cement slurry can ooze people's stone material.Because alkaline matter is comparatively strong to the adsorptive power of water, in malaria, when envrionment temperature is higher, will form the alkaline matter containing crystal water, crystal water can change along with the change of temperature, but disappears never, thus form at stone surface the phenomenon that wet trace do not do, be commonly called as water stain.
1.4 crackle
The reason of stone material crackle is caused to have multiple: one is artificial destruction; Two is biotic influences, and as fresh in weeds, tongue, vegetation is attached to stone surface, can increase the storage time of stone surface moisture, make the extended durations of action of water and stone material.Root system of plant can develop along stone material microfracture, causes crack constantly to expand.In addition, after root system of plant rots, can secrete acidic substance, also can accelerate the corrosion of stone material; Three is freeze-thaw damages, and the moisture in stone material hole, when temperature is very low, can freeze, thus produces pyrocondensation cold expanding phenomenon, and stone material also can be made to crack.
1.5 come off
There is hole between stone material and sand-cement slurry contact surface, when moisture content to penetrate in hole and occurs to freeze, can volumetric expansion be produced, make to produce crack between stone material and sand-cement slurry.Soluble salt in hole, when temperature variation, can produce crystalline polamer, volumetric expansion after crystallization, also causes crack to produce.In addition, when extraneous temperature Change is larger, the dilation amount of stone material and sand-cement slurry is greatly different, can produce stress at contact surface, in the course of time, makes to produce between stone material and sand-cement slurry to loosen, causes stone material to come off.
1.6 weathering
The mechanical disintegration that mineral and rocks occurs under surface conditions and chemical decomposition process are called weathering.The most of stone material being exposed to earth's crust surface is all in the physical and chemical condition different from during its formation, and oxygen, carbonic acid gas and water are rich in earth's surface, and thus stone material very easily changes and destroys.The stone material showing as monoblock becomes fragment, or its composition changes, and finally makes hard stone material become loose chip and soil.Earth's surface stone material does not change the effect that its chemical composition do not produce new mineral matter yet and claims physical weathering in former generation Mechanical Crushing.As the expanding with heat and contract with cold of mineral stone material, slabbing and salt-pepper noise etc. all can make stone material become fritter so that completely cracked by bulk.Chemical weathering refers to that earth's surface stone material is subject to the effect of water, oxygen and carbonic acid gas etc. and chemical composition and mineralogical composition change occur, and produces the effect of new mineral matter.Carry out mainly through modes such as solvency action, hydration, hydrolytic action, carbonation and oxygenizements.
So; fundamentally to address these problems the top priority of generation; exactly before installation, use, special stone protectant is brushed to stone material; perform waterproof, antifouling pre-treatment; only has the real contact of fundamentally stopping stone material and moisture content; just can play the effect of prevention stone material illness, the attractive in appearance of protection stone material could be talked and increase the service life.The Main Function of stone protectant makes it infiltrate stone surface by brushing protective agent exactly, prevents stone material to be subject to extraneous pollution, reduces stone material water suction.Like this, the generation of the various illnesss of stone material will be reduced widely.
Summary of the invention
For above shortcomings in prior art, the invention provides one and prevent the various pathology of stone material, improve the fullness ratio of stone material own, fullness of shade, texture, permeability and surface hardness and there is stone surface protection nano coating that is easy to clean, stain resistant.
Meanwhile, present invention also offers a kind of technique preparing stone surface protection nano coating.
