Description

Ardealite block and preparation method thereof
Technical field
The invention belongs to gypsum block technical field, and in particular to a kind of Ardealite block and preparation method thereof.
Background technology
Gypsum hollow block be usually using plaster of Paris production new internal partition wall materials for wall, due to its low cost, Lightweight, waterproof, and meet low-carbon (LC), environmental protection, energy-saving, make simple, high insulating effect, sturdy and durable the advantages of extensively should For building internal partition wall, so creation is a kind of to have become gypsum hollow block by the use of new trade waste as main material The dominant direction of exhibition.
Produce in prior art the method for gypsum block mainly with calcining after Gypsum Fibrosum preparata, i.e. semi-hydrated gypsum is main former Material.But by the chemical gypsum (such as ardealite etc.) in various industrial wastes by calcining be changed into Gypsum Fibrosum preparata need to expend more Heat energy or the energy, do not meet the strategic requirement of low-carbon (LC), energy-conservation.And also there is shortcoming as is evident below in this production technology:
(1), need supporting huge as avoided because producing substantial amounts of dust by serious environment pollution in calcination process Cleaner, take up an area many, investment greatly;
(2) need because being dehydrated and drying, need dehydration and the drying equipment of matched price costliness again;
(3) the gypsum block rupture strength and comprcssive strength for preparing is affected by factors such as exciting agents, its effect one Directly undesirable;
(4) it is used for accommodating the room of EDP equipment or for neighbouring mobile communication or the building of other transfer stations, it is desirable to increase The capability of electromagnetic shielding of construction material used, but existing gypsum block does not but have this performance.
Content of the invention
The present invention proposes a kind of Ardealite block, and not only bending and compressive strength is high for the gypsum block, and shielding attenuation effect Fruit is significantly.
The technical scheme is that and be achieved in that:
A kind of Ardealite block, in parts by weight, including following raw material:
40~50 parts of ardealite, 1~4 part of graphite oxide, 5~10 parts of slag powders, 1~3 part of sodium stearate, cement 8~12 Part, stearic acid -1~3 part of polystyrene emulsion waterproofing agent, 0.5~1.5 part of reinforcing agent, 0.2~0.8 part of water reducer and compound 2~5 parts of exciting agent, above-mentioned raw materials sum are 100 with the mass ratio of water:15~30, the composite exciting agent is by 5~10wt% Sodium hydroxide and 90~95wt% sodium metaaluminate composition.
Further, the cement is Portland cement 42.5, Portland cement 42.5R, normal silicate water Mud 52.5 or Portland cement 52.5R.
Further, the water reducer is lignin sulfonate water reducer or polycarboxylic acid series high efficiency water reducing agent.
Further, the reinforcing agent is glass fibre or Plant fiber.
It is a further object to provide a kind of preparation method of Ardealite block, comprises the following steps:
1) each dispensing is accurately measured according to the weight proportion of the dispensing;
2) by ardealite and graphite oxide 30~60min of mixed grinding;
3) by each solid ingredient mix homogeneously, every other composition and water are injected simultaneously into mixing;
4) compound for stirring is poured into die for molding, depanning after 24~48 hours is dried in the air under natural ventilating environment Dry obtain final product building block finished product.
Beneficial effects of the present invention:
1st, the present invention adds graphite oxide in ardealite raw material, according to DIN EN50147-1, in magnetic field, plane wave and The gypsum block shielding attenuation effect is significant is measured under the frequency of microwave field type.
2nd, the exciting agent that the sodium metaaluminate using sodium hydroxide and 90~95wt% by 5~10wt% of the invention is constituted, The activity of this non-viable material of ardealite is made to be excited and be improved, it is to avoid traditional exclusive use sodium hydroxide is used as exciting " returning frost " phenomenon (addition of exciting agent exceedes certain value, and strength character drastically declines) that agent occurs, this is probably meta-aluminic acid Sodium solves the problems, such as to cause slag to dissolve in a large number due to a large amount of sodium hydroxide individualisms.The anti-folding of the gypsum block of the present invention Intensity is 4~5MPa, 20~25MPa of comprcssive strength.
3rd, add sodium stearate in Ardealite block raw material of the present invention and stearic acid-polystyrene emulsion waterproofing agent improves Its moistureproof wet performance, coefficient of softing reach 0.8~0.9.
