Abstract

The invention relates to a natural-anhydrite-based inner wall plastering gypsum material for mechanical spraying, and the material is applied to the building field.Aggregate sand and powder are matched according to the ratio of 1:1; the powder is prepared from, by weight, 65-80 percent of natural anhydrite powder, 3-5 percent of building gypsum, 5-10 percent of alkali activator, 5-10 percent of lightweight aggregate, 0.3-1.0 percent of acid activator, 0.2-0.5 percent of water-retaining agent and 0.2-0.5 percent of retarder.According to a preparation method of the material, ground gypsum powder is metered according to the weight percent in the claim 1 and mixed to be uniform in a mixer, and then the natural-anhydrite-based inner wall plastering gypsum material for mechanical spraying is prepared.In the construction process, the material has good stability, water-retaining performance and sagging; the bonding performance is high, and the adhesive force between the product and a base material is increased; the plastering area is large, unit cost is low, compatibility is good, and mechanical construction is convenient.

Description

Natural anhydrite base mechanically spraying plastering on inner walls gypsum material and preparation method thereof
Technical field
The present invention relates to building material technical field, be specifically related to a kind of natural anhydrite base mechanically spraying plastering on inner walls gypsum material and preparation method thereof;It is mainly used in the construction of plastering on inner walls machineryization, can be used for extending old building, concrete wall, all kinds of plastering on inner walls machineryization construction 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, being continually changing with market, the construction of plastering on inner walls machineryization progressively replaces artificial construction, various exploitations for the plastering on inner walls gypsum material of mechanical execution are concentrated mainly on develops with semi-hydrated gypsum, plaster of Paris, desulfurated plaster etc. for base material, and China's rich reserves, the natural anhydrite that grade is excellent there is no people and develops.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 mechanically spraying plastering material 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 mechanically spraying plastering on inner walls gypsum material, is carried out proportioning with aggregate by weight 1:1 by powder and makes, and wherein, powder is made up of following components in percentage by weight:
Described aggregate is sand;
Alkali-activator used by the present invention selects ash calcium or 42.5 cement, it is possible to for any one or two or more mixing.
In the present invention, acidic activator includes potassium salt series exciting agent, sodium salt series exciting agent, transition metal sulfate, it is possible to for any one or two or more mixing, 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, retarder elects what Linyi, Shandong produced as.
In the present invention, aglite selects expanded perlite or glass bead, it is possible to for any one or two or more mixing, is any proportioning during two or more mixing.
Sand used in the present invention be clay content less than 3%, the fine sand of below particle diameter 1.18mm.
In the present invention, natural anhydrite powder 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 3500 4500cm2/g。
The preparation method of the present 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 3500~4500cm2/g;
2) alkali-activator has been measured by weight percentage, acidic activator, water-retaining agent, retarder, aglite and the appropriate abundant premixing of natural anhydrite powder measured;
3) premixing flour is sufficiently mixed uniformly with the building gypsum plaster measured in a large number, sand in batch mixer.Material.
During onsite application, add water stirring with the mixing water amount of the ratio of mud 0.25 0.40.
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, increase unit to plaster area, reduce use cost, improve the market competitiveness.Particularly with natural anhydrite, having adhesive property good, the more high feature performance benefit of intensity, therefore this product will occupy an important position in mechanical execution plastering material for inner wall series of products.
The invention has the beneficial effects as follows: the natural anhydrite type mechanically spraying plastering on inner walls gypsum material adhesive strength of present invention natural anhydrite preparation is high, area of plastering is big, and unit cost is low, and workability is beneficial to mechanical execution well, 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 mechanically spraying plastering on inner walls gypsum material, is made up of natural anhydrite powder, exciting agent, water-retaining agent, plaster of Paris, aglite, retarder, aggregate.Environmental condition according to application, by adjusting the formula of invention, it is possible to obtain required performance.Concrete example is as follows, by kilogram:
