Abstract
The invention discloses an insulation building gypsum powder with a mosquito-repellent effect. 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 strength, large porosity and remarkable insulation effect, and has a mosquito-repellent effect. In addition, the technological process is short, calcination temperature is low, cost is low, and product quality is stable.
Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of heat-preserving building Gypsum Fibrosum powder with mosquito repellent function 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 heat-preserving building Gypsum Fibrosum powder with mosquito repellent function and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
