Abstract

The invention discloses semidry-process desulfurization ash putty for an interior wall. The putty for the interior wall comprises the following components (in percentage by mass): 25-35% of semidry-process desulfurization ash, 10-20% of steel slag, 30-45% of superfine slag powder, 10-25% of calcium-magnesium powder, 0-5% of water retaining agent and 0-5% of emulsion powder. According to the invention, people can know that the putty is prepared by taking waste steel slag generated by steel slag enterprises, mineral slag and desulfurization slag instead of heavy calcium carbon as raw materials, therefore, when a mixture obtained after putty powder is mixed with water is used for coating a wall, the water resistant performance of the wall can be good, and the growth of mildews growing under a humid survival condition is also inhibited; the prepared putty wall is mild in color, therefore, a favorable decoration effect can be achieved.

Description

A kind of semi-dry desulphurization ash inner wall putty
Technical field
The application relates to metallurgical environmental protection technical field, relates in particular to a kind of semi-dry desulphurization ash inner wall putty.
Background technology
Semi-dry desulphurization ash is a kind of by product that Steel Plant's semi-dry process flue gas desulphurization system produces, and owing to not utilizing preferably approach, mainly saves as master with heap at present.Along with increasing of semi-dry desulphurization project, the generation cumulative year after year of desulphurize fly ash, according to statistics, a 360m 2sinter machine adopts full flue gas desulfurization, produces every year 4～50,000 tons, and desulphurize fly ash major ingredient is calcium sulfite, calcium sulfate, calcium carbonate and calcium hydroxide.At present, desulphurize fly ash many as additive for the preparation of cement, brick or inorganic materials, because desulphurize fly ash Central Asia calcium sulphate content is higher, when its practical application, be subject to various restrictions.And a kind of industrial residue producing when simultaneously slag is steel-making, its quantity is generally 10%～20% of crude steel output, and generation is huge.The generation of national slag in 2006 is about 0.7 hundred million tons, and the comprehensive utilization ratio of slag only has 20% according to incompletely statistics.The shortcomings such as traditional process for treating steel slag ubiquity floor space is large, processing environment is seriously polluted, devices consume is large; Simultaneously general modified method, conventionally because active oxidation calcium contents in slag is high, unstable, cannot be promoted the use of normally.Storing up in a large number of slag, has brought a large amount of dust pollutions to the on-site environment of iron and steel enterprise, has also taken in a large number valuable land resources, " the dual waste " of this resource of being known as in environmentalism simultaneously.
Putty is supplementary material important in architectural finish process, plays the effect of transition at basic unit and film between this, eliminates the surface imperfection of basic unit, and satisfactory flat basic unit is provided.Tradition putty powder is taking coarse whiting as main, and be aided with the industrial chemicals such as glue, ripe rubber powder, chemical paste is matrix material simultaneously, is synthesized by artificial Site.In glue, contain the harmful composition such as benzene, formaldehyde, in putty powder, taking coarse whiting as main raw material, water tolerance is poor, is prone to mould and breed bacteria, and this phenomenon causes that metope is attractive in appearance has a greatly reduced quality.Tradition putty powder tone is single, lacks gloss, and general interior decoration relies on emulsion paint toning.
The present invention is directed to semi-dry desulphurization ash can not be used for production of construction materials technical bottleneck without ageing and stabilization treatment, adopt desulphurize fly ash and slag micropowder-slag compounding technology to produce inner wall putty, not only can effectively solve desulphurize fly ash and store up the pollution problem bringing, the bad problem of stability simultaneously can solve slag and make building materials adulterant time.
Summary of the invention
The present invention a kind of semi-dry desulphurization ash inner wall putty is provided, to solve the poor water resistance of traditional putty, be prone to mould and breed bacteria, and then cause metope technical problem of having a greatly reduced quality attractive in appearance.
For solving the problems of the technologies described above, the invention provides a kind of semi-dry desulphurization ash inner wall putty, the composition of described inner wall putty is (according to mass percent): semi-dry desulphurization ash 25%～35%, slag 10%～20%, slag micropowder 30%～45%, dry powder 10%～25%, water-holding agent 0%～5%, latex powder 0%～5%.
Preferably, the preparation method of described inner wall putty comprises: semi-dry desulphurization ash is dried, so that the water content of described semi-dry desulphurization ash is less than 1% of sole mass; Slag is dried, and use grinding of ball grinder powdering; Industrial slag is dried, and wear into slag micropowder; By 25%～35% semi-dry desulphurization ash, 10%～20% powdery slag, 30%～45% slag micropowder, 10%～25% dry powder, 0%～5% water-holding agent, 0%～5% latex powder drops in stirrer simultaneously, utilizes centrifugal three axle stirrer mix 5 minutes～15 minutes, obtains described inner wall putty.
Preferably, described utilize centrifugal three axle stirrer mix 5 minutes～15 minutes after, described method also comprises: utilize packing machine overlay film packaging or air pressure pump that described inner wall putty is sent in vacuum tank and stored.
Preferably, described by slag oven dry, and use grinding of ball grinder powdering, be specially: described slag is dried, and use grinding of ball grinder powdering, so that the fineness of powdery slag is greater than 350 orders, and water content is less than 1% of sole mass.
Preferably, the specific surface area of described slag micropowder is greater than or equal to 450m 2/ kg.
Preferably, described semi-dry desulphurization ash refers to the desulphurize fly ash that Steel Plant's semi-dry process flue gas desulphurization system produces.
By one or more technical scheme of the present invention, the present invention has following beneficial effect or advantage:
Semi-dry desulphurization ash inner wall putty of the present invention, the composition of inner wall putty is (according to mass percent): semi-dry desulphurization ash 25%～35%, slag 10%～20%, slag micropowder 30%～45%, dry powder 10%～25%, water-holding agent 0%～5%, latex powder 0%～5%.As can be seen here, in the present invention, do not manufacture putty taking coarse whiting as raw material, but taking the waste steel slag of slag enterprise, slag, desulfurization slag as raw material, therefore, use application after this putty powder mixing water, can make metope water resistance good, also suppressed with the humidity growth of the mould under condition for survival; The putty metope of preparation presents soft tone, can obtain good decorative effect.
Further, the present invention manufactures inner wall putty taking waste steel slag, slag, the desulfurization slag of slag enterprise as raw material, and cost is lower.
Further, semi-dry desulphurization ash inner wall putty of the present invention, containing glue, has eliminated the injury of the objectionable impuritiess such as formaldehyde to human body containing in glue in its raw material, and cement not, has alleviated the discharge of CO2 to the Greenhouse effect of atmosphere.
