Abstract
The invention relates to a whitening agent for an ardealite ceiling. The formula of the whitening agent comprises the following components in percentage by weight: 10-15% of a degreasing agent, 8-10% of lithopone, 8-10% of aluminum silicate, 8-12% of a surfactant, 25-35% of water, 28-32% of a thickening agent, 1-3% of table salt and 4-6% of caustic soda flakes, wherein the total percentage of all the components is 100%. A method for preparing the whitening agent for the ardealite ceiling by adopting the above formula comprises the following steps: putting the caustic soda flakes into water, blending by using a stirrer, sequentially adding the degreasing agent, lithopone, aluminum silicate, the surfactant and the thickening agent in proportion, stirring continuously to ensure that the components are fully fused, gradually adding an appropriate amount of the table salt, and stirring to from a paste. The whitening agent provided by the invention is simple and convenient in preparation method and low in cost, and white cement does not need to be added again or can be reduced in the product process, so that the product cost can be further reduced.
Description
Technical field
The invention belongs to building material field, particularly a kind of ardealite ceiling whitening agent.
Background technology
Gypsum plaster ceiling board is that main raw material blast blending and fiber are made with the plaster of Paris, has light weight, thermal insulation, sound absorption, fire-retardant and the performance such as can to saw.Gypsum plaster ceiling board be a kind of lightweight, intensity is higher, thinner thickness, easy to process and sound insulation is adiabatic and the material of the better performances such as fire prevention, is one of novel light sheet material of current development emphatically.Be widely used in writing the medium and high classes buildings such as office building, market, hotel, studio hall, waiting room, also adopt by the upholstery furred ceiling of the high humidity environments such as some underground workss.The true qualities of gypsum plaster ceiling board are white, and the whiteness required because of its decorative effect is higher, so plaster of Paris uses the plaster of paris usually, cement adds white cement usually.Adopt frying phosphogypsum powder to produce gypsum plaster ceiling board, if do not do whitening technology process, usual Problems existing is that there is greasy dirt etc. on Huang, uneven color, surface partially for the whiteness of material color.Therefore, whitening technology process is the technical measures using phosphogypsum powder to substitute plaster of paris production gypsum plaster ceiling board.
Summary of the invention
The object of this invention is to provide a kind of whitening agent for ardealite ceiling.
A kind of ardealite ceiling whitening agent, the weight percent of its formula is: grease-removing agent 10 ~ 15%, lithopone 8 ~ 10%, pure aluminium silicate 8 ~ 10%, tensio-active agent 8 ~ 12%, water 25 ~ 35%, thickening material 28 ~ 32%, salt 1 ~ 3%, sheet alkali 4 ~ 6%, and each component sum is 100%;
The method adopting above-mentioned formula to prepare ardealite ceiling whitening agent is:
First sheet alkali is put into water, mix and stir with agitator, then drop into grease-removing agent, lithopone, pure aluminium silicate, tensio-active agent, thickening material continuation stirring successively in proportion, make it fully merge, progressively add appropriate salt and stir, become starchiness.
The preferred weight percent of above-mentioned formula is: grease-removing agent 12%, lithopone 8%, pure aluminium silicate 8%, tensio-active agent 10%, water 28%, thickening material 28%, salt 2%, sheet alkali 4%.
Whitening agent of the present invention is applied in gained ardealite ceiling in the frying phosphogypsum powder gypsum plaster ceiling board course of processing that is raw material, color and luster is bright, good looking appearance in vain, there is no the greasy dirt vestige such as circle line or spot of black, and the preparation method of this whitening agent is easy, with low cost, production process does not need to add or reduce to add white cement, greatly can reduce product cost.
Embodiment
Phosphogypsum refers in phosphoric acid production with the solid slag produced during sulfuric acid treating phosphorite, its main component is calcium sulfate, produce 1 ton of phosphoric acid (in 100% P2O5) and produce 4.8 ~ 5.0 tons of phosphogypsums, so adopting phosphogypsum to make raw material production ardealite ceiling is a kind of utilization of waste material, become refuse into precious environmental protection invention.
What the raw materials for production of ardealite ceiling adopted is frying phosphogypsum powder, is the phosphogypsum raw material of Phosphate Fertilizer Industry waste ardealite fecula after calcining.Because the foreign matter content of frying phosphogypsum powder is higher, its gypsum content, whiteness etc. do not have the height of the plaster of paris, if the gypsum plaster ceiling board produced with frying phosphogypsum powder is without brightening process, appearance color is partially yellow, whiteness is inadequate, color is uneven, or have circle line or the spot of black, larger with the plasterboard difference produced with natural gesso.Therefore the present invention has gone out a kind of novel whitening agents for this Study of Defects specially, and this novel whitening agents is the improvement carried out on the basis of existing whitening agent.
The batching of ardealite ceiling whitening agent of the present invention is (weight percent):
Grease-removing agent 10 ~ 15%, lithopone 8 ~ 10%, pure aluminium silicate 8 ~ 10%, tensio-active agent 8 ~ 12%, water 25 ~ 35%, thickening material 28 ~ 32%, salt 1 ~ 3%, sheet alkali 4 ~ 6%, each component sum is 100%.
The method adopting above-mentioned formula to prepare ardealite ceiling whitening agent is:
First sheet alkali is put into water, mix and stir with agitator, then drop into grease-removing agent, lithopone, pure aluminium silicate, tensio-active agent, thickening material continuation stirring successively in proportion, make it fully merge, progressively add appropriate salt and stir, become starchiness.
Above-mentioned formula is by repeatedly facts have proved, its preferred weight percent is:
Grease-removing agent 12%, lithopone 8%, pure aluminium silicate 8%, tensio-active agent 10%, water 28%, thickening material 28%, salt 2%, sheet alkali 4%.
Principle of the present invention: one is that the emulsified substance simultaneously in brightener formulations with hydrophilic group and oleophilic group can adsorb the suspended impurity forming uneven, even black circle line or spot the greasy dirt class of material surface color in frying phosphogypsum powder be fixed in the weave construction of plasterboard, reduce at the amount of material surface, thus reach brighten, the effect of color even; Two be the calcareous component content of frying phosphogypsum generally at 92%-93%, in the composition of all the other 7%-8% except the suspended impurity of a small amount of greasy dirt class, mainly siliceous composition, so can reduce adding or no longer adding white cement of white cement.
Adopt whitening agent of the present invention can increase early strength in the plasterboard course of processing and the easily demoulding, not sticking to mould, the plasterboard processed, color and luster brilliant white, evenly, and can not turn to be yellow for a long time, be particularly suitable for decoration industry.Phosphogypsum powder is a kind of waste for Phosphate Fertilizer Industry, if produce the enterprise of plasterboard, the raw material of employing is phosphogypsum powder, then greatly can reduce production cost, increase economic efficiency.
