Abstract
The invention relates to preparation of anti-sagging dry-blending plastering mortar by means of molybdenum tailing sand. In a preparation method, the anti-sagging dry-blending plastering mortar is prepared from, by weight, 50%-85% of the molybdenum tailing sand, 10%-30% of cement, 3%-5% of redispersible rubber powder, 0.2%-0.8% of easily-dispersed fibers, 0.2%-0.6% of a thixotropic lubricant and 0.15%-0.4% of methylcellulose, wherein the thixotropic lubricant and the methylcellulose also can be replaced by starch ether and hydroxypropyl methyl cellulose. According to the preparation of the anti-sagging dry-blending plastering mortar by means of the molybdenum tailing sand, the molybdenum tailing sand which harms the environment at present, is abandoned and not used and needs to be managed can be consumed in quantity, and the non-renewable resource natural sand is saved; on the other hand, the stability and anti-sagging property of the mortar are improved, the bad phenomena that bleeding occurs when the mortar is stored, and the mortar sags or clots when construction is performed are reduced, one-time construction can be achieved, the sagging or slippage phenomenon cannot occur, and the construction efficiency can be improved by one time or above.
Description
Technical field
The present invention relates to a kind of dry-mixed plastering mortar of building field, especially a kind of method utilizing molybdenum tailing sand to prepare sag prevention motar.
Background technology
The mine tailing waste residue slag that to be mining firm discharge after to ore selecting and purchasing, and the ratio shared by it is " huge ", and such as the county processes the molybdenum ore of 10000 tons day, and its CHARACTERISTICS OF TAILINGS SAND of discharging just reaches 8750 tons.It is arranged outward with slurry form, and accumulate over a long period formation Tailings Dam.Tailings Dam floor space is large, and has potential safety hazard, and the beneficiation reagent tailings water be rich in Tailings Dam in addition penetrates into underground, and to environment, underground water also can cause great pollution.
Northern area winter climate is cold, present rural area and cities and towns, to newly constructed house or extending old building, are selected to be generally that polyphenyl foam is placed in indoor top to furred ceiling, are being smeared the form of one deck mortar as furred ceiling, to reach the effect of heat preservation energy-saving, instead of the way that lime smeared by original reed curtain.Therefore, preparation is applicable to furred ceiling sag prevention motar used, seems particularly important.
Therefore, utilize environmentally hazardous molybdenum tailing sand, replace that current resource is closely exhausted and large portion prohibits the natural river sand adopted, prepare and be applicable to furred ceiling sag prevention motar used, to Resources for construction saving type, friendly environment society is significant.
Summary of the invention
The technical problem to be solved in the present invention will provide one to utilize molybdenum tailing sand to substitute natural river sand, sag prevention exactly, the dry-mixed plastering mortar that workability is good.
For solving the problems of the technologies described above, technical scheme provided by the present invention is, following weight percents component composition pressed by described mortar.
Preferred as technical scheme provided by the present invention, following weight percents composition pressed by described mortar.
Cement of the present invention is ordinary Portland cement, PO32.5 or PO42.5.
Molybdic tailing sand of the present invention, its dioxide-containing silica more than 75%, granularity is 50 order ~ 120 orders, water content less than 5%, silt content less than 1%.
Redispersable latex powder of the present invention is Vinyl Acetate Copolymer class redispersion latex powder.
Easy loosen collagen fibre of the present invention is the special cracking resistant for mortar research and development, and length pole is joined, the fiber of inorganic.
Thixotropic lubricant of the present invention is neusilin.
Starch ethers of the present invention is that the natural polymer modification of polyose forms.(as potato, corn, cassava etc.)
Methylcellulose gum of the present invention, according to season, the corresponding viscosity grade of terrain selection.
Ylmethyl Mierocrystalline cellulose in hydroxyl of the present invention, according to season, the corresponding viscosity grade of terrain selection.
Adopt technical scheme of the present invention, a large amount of consumption is endangered environment at present, the molybdic tailing sand of giving it up, save Nonrenewable resources natural sand, improve on the other hand stability and the sag resistance of described mortar, overcome bleeding when mortar is deposited, during construction mortar sagging or conglomeration bad phenomenon, and can not produce sagging or sliding phenomenon by one-off construction, operating efficiency more than one times can be improved.
Embodiment
Embodiment 1: by molybdenum tailing sand drying treatment, make its water content less than 5%, containing mud less than 1%, granularity is 50 ~ 100 orders, then by the CHARACTERISTICS OF TAILINGS SAND of 70%, the silicate PO32.5 cement of 25%, 4% redispersable latex powder, 0.2% easy loosen collagen fibre, 0.3% thixotropic lubricant, 0.2 methylcellulose gum mixes through Agravicmixer, be dry mixed sag prevention motar.
, this mortar after tested
Embodiment 2: by molybdenum tailing sand drying treatment, make its water content less than 5%, containing mud less than 1%, granularity is 50 ~ 100 orders, then by the CHARACTERISTICS OF TAILINGS SAND of 85%, the silicate PO42.5 cement of 20%, 4% redispersable latex powder, 0.2% easy loosen collagen fibre, 0.04% starch ethers, 0.2 HPMC mixes through Agravicmixer, be dry mixed sag prevention motar.
This mortar after tested
Above the preferred embodiment of the present invention and embodiment are elaborated, but the invention is not restricted to the above-described embodiment and examples, in the ken that those skilled in the art possess, can also make a variety of changes without departing from the inventive concept of the premise.
