Abstract
The invention relates to a coating prepared by an industrial waste of microsilica and preparation methods of the coating, belonging to the field of decorative materials. The coating comprises the following components in percentage by weight: 5-90 percent of substrate, 1-70 percent of microsilica, 0-10 percent of an adjuvant, 0-30 percent of pigment, 0-60 percent of a filler, 0-60 percent of a diluent and 0-40 percent of color paste. Moreover, the invention provides the two preparation methods. The industrial waste of microsilica is fully utilized and is changed into valuables, thus the environment pressure is reduced; and due to cheap raw materials, the coating has relatively good cost advantage, and the coating also has the advantages of compactness in structure, good gap-filling effect, firm attachment and delicate color.
Description
Technical field
The present invention relates to a kind of material of construction, relate in particular to a kind of architectural decoration coating material, also relate to its preparation method simultaneously.
background technology:
In current coating technology, typical coating is made up of base-material, pigment, filler, auxiliary agent, thinner, mill base, has no the report and the practice that use industrial waste SILICA FUME.
Industrial silicon and ferrosilicon are in the process of high melt, and the dust of overflowing with waste gas is called SILICA FUME, and its major ingredient is SiO
2, the SiO in flue gas
2content accounts for 94% of amount of flue gas emission.Its granularity is very little, and median size is about 0.3um, and it can directly enter human body alveolar by breathing, very big to human health damage.China has thousands of ferrosilicon and industrial silicon furnace at present, produce approximately 250,000 tons of SILICA FUME per year, and now environmental protection equipment collect only have 60,000 tons of left and right, and a large amount of SILICA FUME is discharged in atmosphere, directly polluted atmospheric environment, be also the waste to resource simultaneously.That has collected also causes accumulation, idle because utilization ratio is not high, take storage.
Chinese patent 201210035276.4 discloses " a kind of silicon slurry and preparation method thereof ", is the field close with the present invention, different formulas and method.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide that a kind of compact structure, calking that utilizes industrial waste SILICA FUME to make is good, the coating of adhere firmly, color and luster grace.
Another object of the present invention is also to provide the preparation method of this coating that utilizes the making of industrial waste SILICA FUME.
The coating that utilizes industrial waste SILICA FUME to make of the present invention, is made up of base-material, SILICA FUME, auxiliary agent, pigment, filler, thinner, mill base, and the weight proportion of each component is:
Base-material: 5%-90%,
SILICA FUME: 1%-70%,
Auxiliary agent: 0%-10%;
Pigment: 0-30%;
Filler: 0-60%;
Thinner: 0%-60%;
Mill base: 0-40%.
The above-mentioned coating that utilizes industrial waste SILICA FUME to make, wherein base-material is synthetic resin emulsion or solvent type resin, its effect is film coalescence.
The above-mentioned coating that utilizes industrial waste SILICA FUME to make, the effect of SILICA FUME is to form chemical bonding as active filler and alkaline basic unit, strengthen the bonding force with basic unit, and stop up basic unit space, improve basic unit's degree of compactness, or improve the degree of compactness of coating itself as micro-filler, or eliminate coatingsurface gloss with the specific surface area of its super large, form graceful mercerising or the effect of dumb light, expand the volume of coating simultaneously.Certainly the color and luster that, SILICA FUME is greyish white can make its restriction to some extent in the application of making pure white coating.
The above-mentioned coating that utilizes industrial waste SILICA FUME to make, wherein auxiliary agent is one or more the mixture in dispersion agent, wetting agent, defoamer, sanitas, mould inhibitor, thickening material, flow agent, film coalescence aid, acid-base modifier.
One of preparation method of the coating that utilizes the making of industrial waste SILICA FUME of the present invention, step is: open stirrer, be adjusted to low speed, by part thinner, part of auxiliary, all SILICA FUME of formula required amount, pigment, filler weighs respectively, drop in stirrer and stir, being adjusted to high speed dispersion to fineness meets the requirements again, or in sand mill and High shear device, be dispersed to and require fineness again, in paint equipment, add again the base-material of the required amount of filling a prescription, the auxiliary agent of remainder, thinner, mill base stirs, filter, inspection, quantitative package, .
One of preparation method of the coating that utilizes the making of industrial waste SILICA FUME of the present invention, step is: open stirrer, be adjusted to low speed, by part or all of base-material, partly or entirely thinner, part of auxiliary, the SILICA FUME that formula requires, pigment, filler, weigh respectively, drop in stirrer and stir, being adjusted to high speed dispersion to fineness meets the requirements again, or in sand mill and High shear device, be dispersed to and require fineness again, in paint equipment, add again the base-material of remainder, auxiliary agent, thinner, mill base stirs, filter, inspection, quantitative package, .
SILICA FUME particle diameter in industrial waste is little to micron, and has basic active, utilizes these performances, can be turned waste into wealth, and makes the coating of excellent property.Due to the SILICA FUME that contains fine particle size, compact structure is brushed to after above-mentioned alkaline basal plane this coating, and SILICA FUME can partly infiltrate in basal plane space, and with its generation alkali active reaction, stop up space, improve basal plane degree of compactness.Also can directly there is alkali active reaction with basal plane, form chemical bonding with basal plane, strengthen the sticking power with basal plane.By adjusting addition, also can utilize the high surface area of SILICA FUME to eliminate the gloss of coating, form graceful mercerising or dumb light effect.In the time making grey colour system coating, also can utilize the grey color of SILICA FUME itself, save mill base expense.
The present invention compared with prior art, the object of the invention is to make full use of industrial waste SILICA FUME, and it is turned waste into wealth, and alleviates environmental stress.Owing to having added cheap industrial waste SILICA FUME, coating has good cost advantage, simultaneously basic active, bigger serface, the minute diameter of SILICA FUME make coating have good technical performance index, as good in compact structure, calking, adhere firmly, color and luster grace etc.Its typical use is the building priming paint for alkaline basal planes such as cement concrete, sand-cement slurry, lime mortars, also can flexible Application in other application occasion.
