Technical field
The present invention relates to a kind of material of construction, especially relate to a kind of light-weight environment-friendly leveling putty.
Background technology
Present China is Development of China's Urbanization fast, has not only brought high buildings and large mansions for the city, has more brought hundreds of millions of building wastes.Building waste is meant dregs, spoir that construction, unit in charge of construction or individual build, lay or remove, produce in the repairerment process all kinds of buildingss, structures etc., abandons material, surplus mud and other wastes.Produce the about 500-600 ton of building waste according to each ten thousand square metres of new buildings of measuring and calculating, and it is surprising especially to remove the rubbish that old building produces, approximately every square metre of building waste that generation is about a ton.Owing to abide by the law cost much larger than illegal cost, the legal disposable of building waste becomes present universal phenomenon.On the one hand, because of building waste by disposable or simple landfill, take up an area of again and pollute, and destroy Soil structure, cause ground settlement; On the other hand, the construction refuse regenerated enterprise that disposing capacity arranged is the former material of building waste for want of but, is faced with the existence awkward situation of " not haveing enough to eat ".There are data to show, China's building castoff resource utilization rate less than 5%, and the annual resource utilization rate of European Union member countries surpasses 90%, Korea S, Japanese architecture changing rejected material to useful resource rate reach more than 97%.Urban construction, transformation are all being carried out every day; building waste every day is all in uninterrupted generation; the building waste work of treatment of China is very urgent; along with China for protecting farmland and the promulgation and the enforcement of every laws and regulations of environment protection, how handling and discharge building waste has become the important topic that enterprise in charge of construction and environmental protection department face.
The main composition material of leveling putty of existing indoor decoration has white cement, grey calcium powder, lime carbonate, talcum powder, whether can utilize urban architecture rubbish better, building waste is applied to the putty filler after treatment, and this becomes the problem of inventor's research.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of light-weight environment-friendly leveling putty that uses the construction waste stone flour as filler, and its constructional method also is provided simultaneously.
For solving the problems of the technologies described above, the invention provides. a kind of light-weight environment-friendly leveling putty, it is characterized in that, mix by the component of following parts by weight proportioning:
Described light-weight aggregate is that fineness is lower than the inorganic vitreous hollow microporous material of 100 purposes;
Described antibacterial and mouldproof composite assistant is the antibacterial and mouldproof composite assistant that the synthetic trading company in Guangzhou sells, and per kilogram antibacterial and mouldproof composite assistant is mixed for 0.2 kilogram by 0.4 kilogram of antibacterial and mouldproof composition, 0.1 kilogram of water-holding agent, 0.3 kilogram of redispersable latex powder and air entrapment agent composition.

Described cement is white cement.
The fineness of described inorganic vitreous hollow microporous material is the 60-100 order.
Described white lime fineness is more than 300 orders.
Preferred described light-weight environment-friendly leveling putty is characterized in that, is mixed by the component of following parts by weight proportioning:
Simultaneously, the present invention also provides the constructional method of described light-weight environment-friendly leveling putty, it is characterized in that, with described light-weight environment-friendly leveling putty thin up, the dilution weight ratio is a putty: water=100: 30-50, mechanical or manual stirring reaches the conventional experience viscosity that is fit to mechanically spraying or manual construction until mixing, and can carry out automatic arc spraying construction or manual construction.
Because building waste is after sorting, fragmentation, screening processing, can be used as the regeneration aggregate resource mostly and utilize again, at the building waste problem of government's headache, we utilize the waste material stone flour of being made by building waste that reclaims that factory sells, substitute the various fillers in the putty, make putty.So, strengthened utilization to building waste, reduce stacking, the landfill of building waste, vegetation, arable land, air and waters are polluted, make appearance of the city health clean and tidy, reduce bacteria breed, savablely stack land area because of burning common brick destructive cultivated area, building castoff landfill, to airborne release carbonic acid gas tonnage, the building castoff processing costs all will be surprising numeral.Save natural mineral resource, really accomplish the recycle of material, have remarkable meaning solving shortage of the material of construction resources of production and huge energy consumption.
Our environmental protection thinking is to utilize the waste material stone flour of being made by building waste in leveling putty, substitutes the filler in the putty, makes putty.Adopt inorganic vitreous hollow microporous material as light-weight aggregate putty gently to be changed simultaneously, make the putty plaster more suitable cunning of getting up, workability is good, with interior wall mortar Young's modulus coupling, prevents hollowing, ftractures, comes off, and improve the cohesive strength of putty; The present invention also adopts the antibacterial and mouldproof composite assistant, effectively purifies the mouldy and bacteria breed of putty, minimizing putty layer.
We select fineness in the building waste is that the waste material stone flour of 25-100 order (particle diameter is 0.16-0.63mm) is applied in the light-weight environment-friendly leveling putty of the present invention; and the particle diameter of the used ordinary Portland cement of the present invention is less than 0.08mm; used light-weight aggregate is inorganic vitreous hollow microporous material; fineness is below 100 orders, preferred 60-100 order (being that particle diameter is about 0.16-0.25mm).Like this, greater than 0, less than size distribution is all arranged in the 0.63mm scope, grain composition is good, this putty is plastered receive planeness and photo sensitivity behind the light very good, directly the final facing of conduct, be follow-up decorative coveringn also, provide more stable basal plane as coating, ceramic tile etc.
Because the waste material stone flour has inborn hole, this makes putty proportion lighter, and adding inorganic vitreous hollow microporous material can increase the putty space, and both work in coordination with the whole proportion of putty is reduced greatly, are 600-1000kg/m
3Various intergranular sliding-frictional resistances diminish after the lighting, it is more sliding that quality becomes, the bleed effect of the polymer dispersion powder in the antibacterial and mouldproof composite assistant also makes putty become compressible, it is more smooth and easy that the putty plaster is got up, and workability improves, and has also fundamentally solved existing putty because of hollowing, cracking than great generation, plugging, stifled rifle, be unfavorable for technical problem such as mechanized construction, putty of the present invention has improved operating efficiency and construction quality.
According to the rule of " hard the end soft face " (outward from base material; the coat of plaster Young's modulus successively reduces; be that scratch coat mortar Young's modulus should be lower than basic unit; finish coat mortar Young's modulus should be lower than bottom; the putty Young's modulus should be lower than surface layer; by that analogy); inorganic vitreous hollow microporous material can make the putty lightweight; Young's modulus reduces, and on the other hand, the Young's modulus of polymer dispersion powder is lower in the antibacterial and mouldproof composite assistant of adding; be 0.001-10GPa; and the Young's modulus of putty is higher, is 5-10GPa, can reduce the Young's modulus of putty behind the adding auxiliary agent; like this; the putty Young's modulus is lower than the surface layer mortar, and both stress deformation trends are consistent, effectively reduces the hollowing of putty; cracking.
The present invention uses the light-weight environment-friendly leveling putty of construction waste stone flour to adopt the antibacterial and mouldproof composite assistant, polymer dispersion powder in the auxiliary agent spreads in water, merges mutually after meeting water, network structure---latex film with cement plaster formation IPN, it has since stretch mechanism, can apply pulling force at itself and putty riveted joint part,, putty be kept as a whole by internal action power, the cohesive strength of putty improves, and viscosifying power strengthens.This layer latex film can also hinder evaporation of water, (silicate cement is a hydraulic cementing materials to help the aquation of cement than having of juicy, can not only in air, harden, and can in water, harden better, keep and its various intensity of continuation development), thereby strengthen the cohesive strength of mortar, effectively reduce hollowing, cracking, the obscission of putty.Moreover the micropore of inorganic vitreous hollow microporous material can play the development that stops microfracture in the putty block, further stops and reduces the fissured generation of putty, the quality of assurance construction work.
Because select for use waste material stone flour in the building waste as the putty filler, clean level is lower, adds southern humid climate and can often cause the mouldy of metope, the growing of bacterium.Therefore the present invention adds the antibacterial and mouldproof composite assistant, and it can destroy the cell walls of bacterium, makes the interior osmotic pressure of bacterium born of the same parents be higher than born of the same parents' exosmosis and presses 20～30 times, cause membranolysis, the endochylema beyond the region of objective existence is let out, and has so just stopped the metabolic process of microorganism, and microorganism can't be grown and breed.It can also form mocromembrane on putty surface, and acarid etc. is had repellent action efficiently, so just makes putty have antibacterial, the germicidal action of wide spectrum, after testing, 24 hours to streptococcus aureus and colibacillary bacteriostasis rate greater than 90%; Mildew resistance to 6 kinds of comprehensive moulds such as aspergillus nigers reaches 0 grade, and this putty possesses long-lasting characteristics, has very high security simultaneously, to the human body skin nonirritant.
The waste material stone flour has inborn hole; inorganic vitreous hollow microporous material can increase the putty space, and this has strengthened the sound-absorbing soundproof effect of putty layer, and both have reduced the material usage of unit surface jointly; lighting makes vertical-lift weight also reduce greatly thereupon, thereby reaches effectively energy-conservation.
Light-weight environment-friendly leveling putty of the present invention utilizes waste material stone flour that building waste makes as the putty filler, makes putty, has really accomplished the recycle of material.Leveling putty lighting, cracking resistance strengthen, and be good with the basic unit consistency, and easier levelling has improved the operating efficiency and the construction effect of this putty.Also effectively reduce mould, bacteria breed, be more suitable for mold, mechanized construction.Construction technology is simple and practical, unit square rice cheap.Be applicable to the levelling polishing engineering on all upholstery surfaces, have greatly promotional value.
Building waste can be used as the regeneration aggregate resource mostly and utilizes again after sorting, fragmentation, screening processing, and the waste material stone flour that we utilize building waste to make substitutes natural stone-powder, manufactures putty.To advancing the building waste comprehensive utilization, realize that the synchronous propelling of economic benefit, ecological benefits and social benefit, coordinated development are significant, be developing direction from now on, also be the developing direction of China's premixing mortar simultaneously.Made from construction refuse resource not only has huge environmental benefit, also will produce huge economic benefit.Along with the pay attention to day by day of government department to environmental construction, building waste is handled and will be welcome how strong national policy support and vast market space soon.
