Abstract
The invention discloses a mothproof insulation building gypsum powder with high compressive strength. 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 high compressive strength, prevents insects, has large porosity, and has a remarkable insulation effect. Therefore, the defect that building gypsum powder has poor water resistance, low strength, high cost and narrow range of application which are not beneficial to large-scale promotion is solved.
Description
Technical field
The present invention relates to building material technical field, be specifically related to high heat-preserving building Gypsum Fibrosum powder of a kind of insect protected comprcssive strength 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 high heat-preserving building Gypsum Fibrosum powder of a kind of insect protected comprcssive strength and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
The heat-preserving building Gypsum Fibrosum powder that a kind of insect protected comprcssive strength is high, it is characterized in that, be prepared by the raw materials in: natural gypsum 40-42, ardealite 50-51, paper white sludge 15-17, liquid paraffin 9-12, ferroso-ferric oxide 2-4, gamma benzene hexachloride 0.04-0.06, Petropols 10-12, willow root 13-15, bamboo fibre 14-16, triethanolamine borate 7-9, nano-calcium carbonate 4-6, nanometer aluminium powder 0.02-0.03, suitable quantity of water.
The preparation method of the heat-preserving building Gypsum Fibrosum powder that described a kind of insect protected comprcssive strength is high, 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) willow root drying is pulverized, add the Petropols of molten condition, gamma benzene hexachloride stirring and evenly mixing, be spray-dried and prepare modified willow root powder；
(3) being processed 30-40 minute in 600-700 DEG C of high-temperature activation by paper white sludge, cooling adds bamboo fibre and pulverizes 10-15 minute, and addition nanometer aluminium powder, nano-calcium carbonate, triethanolamine borate, liquid paraffin grind 20-40 minute, dry；
(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, prepare heat-preserving building Gypsum Fibrosum powder comprcssive strength height, insect protected, porosity is big, heat insulation effect is notable, solve building gypsum plaster poor water resistance, intensity is low, cost is high, range is narrow, is unfavorable for the drawback promoted on a large scale.
