Abstract
The invention discloses a light-resistant yellowing-resistant insulation building gypsum powder. Aluminum nano-powder is added into raw materials, and water is added into the materials and all the materials are blended to generate hydrogen, and the hydrogen is released to form a porous structure. In addition, phosphogypsum is creatively roasted, crushed and air-blasted to boiling state, and a vaporous hydrochloric acid solution is sprayed. After improved acid pickling technology for modification, contents of other impurities are reduced, content of CaSO4.2H2O is increased, and cost of traditional acid pickling is reduced. The economical benefit is remarkable. By adding the product into natural gypsum, with compatibility of other effective compound additives and through grinding, lap joint between crystals of a gypsum hardened specimen is denser, and gap between crystals is correspondingly reduced. The prepared insulation building gypsum powder has advantages of light resistance and yellowing resistance, high strength, large porosity and remarkable insulation effect. A building product prepared by the use of the building gypsum powder which is prepared by the method has long service life.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of fast light heat-preserving building Gypsum Fibrosum powder being difficult to yellowing and preparation method thereof.
Background technology
In recent years, organic insulation material exterior wall heat-preserving system fire incident happens occasionally, and brings the biggest loss to the lives and properties of people, and exploitation low-carbon (LC) is extremely urgent with fire-retardant type insulation material.Plaster of Paris has light weight, the good characteristic prevented fires, be incubated, and currently used most common Gypsum Fibrosum is the natural gypsum, but the consumption of chemical gypsum the most quickly increases, and studying more in chemical gypsum is ardealite.Owing to containing a certain amount of impurity in ardealite, having a great impact its comprehensive utilization, in recent years, China's ardealite discharge capacity rapidly increases, and up to the present annual emissions is more than 20,000,000 t.Process to ardealite, currently used " stacking " mode, both take substantial amounts of soil, polluted underground water, bring the biggest financial burden to enterprise again.How by phosphogypsum modification and replace the natural gypsum, it it is our difficult problem of needing to solve.On the other hand owing to the water absorption rate of building gypsum products is high, intensity is low, condensation is fast and poor water resistance so that it is range of application is restricted.
The experimentation of plaster of Paris " ardealite prepare " improves the mechanical property of phosphorus building gypsum plaster by adding water reducer, by ardealite with after hydrochloric acid solution soak acid-cleaning, gesso is prepared by roasting, again by ageing modification, change gesso quality, thus reach efficiently, low cost, low energy consumption utilize the purpose of ardealite.But pickling high cost in this literary composition, having process needs heat consumption high, the shortcomings such as process time length, the building gypsum plaster combination property prepared is low, the most do not possess the functions such as insulation noise reduction, it is necessary existing production technology and dispensing are improved, to prepare efficiently, low cost, the building gypsum plaster that waterproof, intensity height heat insulation effect is excellent.
Summary of the invention
It is an object of the invention to provide a kind of fast light heat-preserving building Gypsum Fibrosum powder being difficult to yellowing and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:

The preparation method of the described a kind of fast light heat-preserving building Gypsum Fibrosum powder being difficult to yellowing, it is characterised in that comprise the following steps:
(1) ardealite is removed through natural air drying the free water of 15-18%, it is crushed to 60-80 mesh, bakee 1-2 hour in 100-105 DEG C, be ground to 100-120 mesh, be cooled to 70-80 DEG C, air blast is to fluidized state, spray the hydrochloric acid solution of vaporific 1mol/L, keep temperature to continue to spray 10-15 minute, stand 10-12 hour, it is washed till neutrality with clear water, obtains pickling ardealite；
(2) fine rice bran drying is pulverized, add the epoxy resin of molten condition, tetramethyl-ammonium iodide, magnesium oxide stirring and evenly mixing, be spray-dried and prepare modified fine rice bran powder；
(3) being pulverized by polypropylene fibre, addition nanometer aluminium powder, starch, enuatrol, tributyl 2-acetylcitrate grind 20-40 minute, dry to obtain modified Nano aluminium powder；
(4) natural gypsum, the mixing of pickling ardealite being ground 1-2 hour, add water ageing 12 hours, filtering drying, roasting 2-3 hour at 170-180 DEG C, it is cooled to 90-100 DEG C, adds step (2), (3) reaction mass and the mixing of other residual components homogenizing, discharging and get final product.
The present invention has following beneficial effect: the present invention adds nanometer aluminium powder in raw material, meet water after water mixing mix and generate hydrogen releasing, form loose structure, additionally the invention by ardealite bakee after pulverize air blast to fluidized state, spray vaporific hydrochloric acid solution, after acid cleaning process modification after improved, reduce other impurity contents, improve CaSO4·2H2O content, and reduce the cost of traditional method pickling, remarkable in economical benefits, join in the natural gypsum and other ground process of effective composite assistant of compatibility, overlap more densely cross-linked between the crystal of gypsum hardenite, diminishing the most accordingly between crystal, the heat-preserving building Gypsum Fibrosum powder prepared have fast light be difficult to yellowing, intensity is high, porosity is big, the significant advantage of heat insulation effect, having the building gypsum plaster prepared by the method and make building product, service life is long.
