Description
Technical field
The present invention relates to building material technical field, be specifically related to a kind of natural anhydrite base light internal wall plastering gupsum material and preparation method thereof；It is mainly used in plastering on inner walls, can be used for extending old building, concrete wall, all kinds of plastering on inner walls adding building block, gypsum block or other light wall material.Range of application is very extensive, to become the requisite supplementary material of building engineering construction.
Background technology
In recent years, the exploitation common reporter of various plastering on inner walls Gypsum Fibrosum, but be concentrated mainly on and develop for base material based on semi-hydrated gypsum, plaster of Paris, desulfurated plaster etc..There is no people and use China's rich reserves, the natural anhydrite exploitation light internal wall plastering gupsum material that grade is excellent.Owing to the production of semi-hydrated gypsum also exists energy resource consumption greatly, seriously polluted, and semi-hydrated gypsum resistance to water is poor.Doing adhesives without calcining, energy-conserving and environment-protective with natural anhydrite, resistance to water is better than semi-hydrated gypsum, so the importance of its exploitation more aobvious.
Summary of the invention
The technical problem to be solved is in that to provide that a kind of resistance to water is high, less costly, technique simple natural anhydrite base mechanically spraying plastering on inner walls gypsum material and preparation method thereof.
The technical problem to be solved realizes by the following technical solutions:
A kind of natural anhydrite base light internal wall plastering gupsum material and preparation method thereof, be made up of natural anhydrite, acidic activator, alkali-activator, water-retaining agent, rubber powder, aglite, the weight percentage ranges of each component following (with natural anhydrous plaster powder and aglite, alkali-activator weight for radix):
Alkali-activator used by the present invention selects ash calcium or quick lime, it is possible to for any one or two or more mixing.
In the present invention, acidic activator includes potassium salt, sodium salt series exciting agent, transition metal sulfate, it is possible to for any one or two or more mixing.It is any proportioning during two or more mixing.
In the present invention, water-retaining agent adopts methylcellulose, hydroxypropyl methyl cellulose (HPMC), hydroxyethylmethyl-cellulose (HEMC), it is possible to for any one or two or more mixing, is any proportioning during two or more mixing.
In the present invention, rubber powder elects the rubber powder that Zhejiang Shen Hua Co., Ltd produces as.
In the present invention, aglite selects expanded perlite or glass bead, it is possible to for any one or two or more mixing.It is any proportioning during two or more mixing.
The natural anhydrite powder of the present invention is that natural anhydrite utilizes industrial ball mills grinding, and fineness controls in 200 mesh sieve margins less than 5%, and specific surface area is at 4000 5000cm2/g。
The preparation method of invention: realized by following steps:
1) natural anhydrite utilizing industrial ball mills grinding, fineness controls in 200 mesh sieve margins less than 5%, and specific surface area is at 4000～5000cm2/g；
2) measured alkali-activator by weight percentage, acidic activator, water-retaining agent, rubber powder, aglite and the abundant premixing of proper amount of gypsum powder measured, be sufficiently mixed uniformly in batch mixer, material.
During onsite application, add water stirring with the mixing water amount of the ratio of mud 0.30 0.45, directly at inner wall render.
The present invention adopts natural anhydrite to produce, natural anhydrite has potential hydration activity, does not need calcining, under certain additive excitation, its product has hardening strength height, water-tolerant, setting time is suitable, adhesive strength is high, the features such as unit cost is relatively low.Do not need calcining due to natural anhydrite, only need grinding, mixing, compare semi-hydrated gypsum base and plaster of Paris, save the energy, reduce and pollute, and mix aglite, increase area of plastering, reduce unit and plaster area cost thus reducing use cost, improve the market competitiveness.Particularly with natural without water anhydrite, having adhesive property good, the more high feature performance benefit of intensity, therefore this product will occupy an important position in plastering material for inner wall series of products.
The invention has the beneficial effects as follows: the natural light internal wall plastering gupsum material adhesive strength of type without water anhydrite of present invention natural anhydrite preparation is high, area of plastering is big, and unit cost is low, both it was manually operable, again can mechanical execution, saving of work and time, is desirable green building material.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with specific embodiment, the present invention is expanded on further.
A kind of natural anhydrite base light internal wall plastering gupsum material, is made up of natural anhydrite powder, exciting agent, water-retaining agent, rubber powder, aglite.Environmental condition according to application, by adjusting the formula of invention, it is possible to obtain required performance.Concrete example following (by kilogram)；
