Abstract
The invention relates to powdered putty for an exterior wall prepared from ultrafine steel slag micropowder, belonging to the technical field of solid waste comprehensive utilization and chemical building materials. Ultrafine steel slag micropowder is used as a main raw material, and a certain amount of cement, desulphurization gypsum, talc powder, emulsion powder and water-retaining agent are added to prepare the powdered putty for the exterior wall after sufficiently and uniformly mixing. The powdered putty for the exterior wall takes industrial solid waste as the raw material, the production cost of the putty for the exterior wall is greatly reduced; the putty is in a powdered state, so that the putty is convenient to transport; the powdered putty for the exterior wall has a simple production process and is convenient to construct; and the powdered putty for the exterior wall has the characteristics of strong bonding force, no cracking, water resistance, alkali resistance and the like.
Description
Technical field
The present invention relates to a kind of powder putty for exterior wall that utilizes superfine steel slag micropowder to make, belong to solid waste comprehensive utilization and chemical building material technical field.
Background technology
Slag is the industrial solid castoff that steel-making converter or electric furnace produce.China's annual output steel surpasses 500,000,000 tons at present, and nearly hundred million tons in the slag of generation, yet the utilization ratio less than 10% of slag add the untreated over the years slag of storing up, and not only take a large amount of arable lands, to the production and the development build-up of pressure of iron and steel enterprise.And contaminate environment, bring serious harm, even people's health brought influence for soil, water body, atmosphere.In the process of steel slag resource utilization, from different aspects and angle slag is used for building trade is the focus that people study always.
Chinese national economy develops rapidly, and various buildings are increased sharply to the demand of material of construction, wherein also comprise exterior wall putty.Utilizing the superfine steel slag particulate to prepare powder putty for exterior wall, as the base treatment material of floating building surface, is the new way of steel slag resource utilization.
Summary of the invention
The purpose of this invention is to provide a kind of is the powder putty for exterior wall of main raw material preparation with the superfine steel slag micropowder.Characteristics such as it is strong that the powder putty for exterior wall of preparation has cohesive force, do not ftracture, water-fast, alkaline-resisting have fully utilized industrial solid castoff simultaneously, have reduced the production cost of exterior wall putty.
The powder putty for exterior wall that utilizes superfine steel slag micropowder to make of the present invention, the composition and the weight percent of this powder putty for exterior wall are as follows:
Superfine steel slag micropowder 50-70% cement 5-15%
Desulfurated plaster 5-15% talcum powder 10-25%
Latex powder 1-3% water-holding agent 0.1-0.3%
Described superfine steel slag micropowder is converter or electric furnace slag, grinding after iron removal by magnetic separation is handled, its specific surface 〉=600m
2/ kg, particle diameter accounts for more than 90% of total mass less than the superfine steel slag micropowder of 30 μ m, metal Ferrum content≤0.5%.
Described desulfurated plaster is the waste residue that is produced behind the means of flue gas desulfurization of power plant, the semi-hydrated gypsum (β-CaSO that forms through calcination processing
41/2H
2And levigate O), to 45 μ m square hole sieve screen over-size≤10%.
Described cement is 42.5 grades or 52.5 grades of ordinary Portland cements.
Described talcum powder is that the selected back of natural talcum ore is pulverized, ground and make, and fineness is 400 orders.
Described latex powder is any in styrene-propene acid, acrylate, the vinyl acetate-ethylene redispersable latex powder, and its fineness is 100 orders.
Described water-holding agent is any of Natvosol, hydroxyethylmethyl-cellulose, Vltra tears.
Above-mentioned raw materials by the proportioning weigh batching, is added in the mixing machine successively, after fully mixing, promptly obtain powder putty for exterior wall.During use, add suitable quantity of water and stir and in engineering, to use.
The powder putty for exterior wall of the present invention's preparation, main raw material is slag and desulfurated plaster, has opened up new approach for the comprehensive utilization of industrial solid castoff, reaches environmental protection, sharp useless double effects.Reduce simultaneously the production cost of exterior wall putty greatly, be convenient to transportation; Characteristics such as configuration technology is simple, and easy construction has with exterior wall basal plane cohesive force by force, does not ftracture, and is water-fast, alkaline-resisting.
