Description
Technical field
The invention belongs to wallboard production technical fields, and in particular to a kind of novel environment friendly ardealite high-strength light walling product
And preparation method thereof.
Background technique
Industrial by-product ardealite is the industrial solid castoff of generation during Wet-process phosphoric acid (WPPA), 1 ton of phosphoric acid of every production
About 4-5 tons of ardealite can be discharged.The a large amount of main processing mode of ardealite is still simple stacking, not only land occupation area,
And it can be polluted to surrounding enviroment.Therefore, the resource utilization of industrial by-product ardealite is always country, industry and society
Focus.
Currently, the most frequently used have backfill pit the method that handles industrial by-product ardealite, production Flocculated Cement agent, prepare sulphur
Ammonium and calcium carbonate, improvement basic soil.These methods have pushed the technology of China's ardealite recycling to develop, but there is safety
And pollution hidden trouble, long flow path invest the disadvantages of big, can not fundamentally solve the Environmental security hidden danger of industrial by-product ardealite
The relatively low status with utilization rate.Meanwhile publication No. is that CN102180700A Chinese patent application is disclosed and a kind of used ardealite
Method to prepare light cellular partition board and building block, product has many advantages, such as lightweight, sound insulation and heat preservation, and produces easy, cost
It is low, pollution-free, but plastering the problems such as that there are intensity is low, poor water resistance, thus limit gypsum partition board, building block and brick
Application and development.
Summary of the invention
In view of the above technical problems, the present invention provides a kind of novel environment friendly ardealite high-strength light walling product and its preparation
Method, the present invention prepare wallboard, building block and brick as primary raw material using phosphorus building gypsum, utilize and mention for ardealite Industrial Solid Waste
Solution has been supplied, to protection environment, has realized that sustainable development is of great significance；And the environment-friendly novel high strength gypsum prepared
Light-weight aggregate brick, building block, plate etc. have the advantages that lightweight, compression strength height, High anti bending strength, water absorption rate are low etc., can be widely applied to
Interior/exterior decoration material.
To achieve the above object, the technical solution adopted by the present invention is that: a kind of novel environment friendly ardealite high-strength light walling
Product is prepared by the raw material of following parts by weight: 5~20 parts of composite granule, 30~80 parts of phosphorus building gypsum, and haydite 10~50
Part, 0.05~0.3 part of retarder, 0.3~1.5 part of water-reducing agent, 0.1~1.0 part of waterproofing agent, 1~5 part of exciting agent, anti-agent of creeping
0.05~0.3 part, 0.01~0.5 part of binder, 40~60 parts of water.
Further technical solution is prepared by the raw material of following parts by weight: 5~20 parts of composite granule, phosphorus building
50~80 parts of gypsum, 20~40 parts of haydite, 0.05~0.15 part of retarder, 0.9 part of water-reducing agent, 0.2~1.0 part of waterproofing agent, swash
1~5 part of agent of hair, anti-to creep 0.05~0.3 part of agent, binder 0.01~0.5,40~55 parts of water.
Further technical solution is that the composite granule is the powder binding material being mixed in a certain ratio.
Further technical solution is that the phosphorus building gypsum is modified self-control ardealite.
Specific modification mode: first passing through neutralisation treatment about 48h, then is dried (105~170 DEG C of temperature) processing, then
Grinding to certain fineness (meets 0.2mm square hole screen and tails over≤10%).
Further technical solution is that the retarder is any one in animal protein class, borax and Citric Acid Mono
Kind.
Further technical solution is that the water-reducing agent is that melamine compounds water-reducing agent with naphthalene system, compounds buck agent
Solid content 15%, water-reducing rate is greater than 25%, to not influence gypsum color, can obviously increase the mobility of gypsum, reduce stone
The viscosity of cream slurry.
Further technical solution is that the waterproofing agent is dissolubility organosilicon or hydrophober such as calcium stearate class.
Further technical solution is that the haydite is self-control haydite, and self-control haydite is using municipal sludge and building slag
Soil, engineering spoir, building micro mist etc. are fired through treatment process, environmental protection and energy saving.
Further technical solution is that the exciting agent is quick lime, for exciting the activity of gypsum mixing material, improves stone
Cream hardenite intensity.
Further technical solution is that the anti-agent of creeping is boric acid or trimethyl sodium phosphate.
Further technical solution is that the binder is latex powder, improves workability, improves mobile performance, is increased
Bend resistance intensity.The exciting agent is quick lime.
A kind of preparation method of novel environment friendly ardealite high-strength light walling product, comprising the following steps:
A, it is uniformly mixed obtained mixture 1 in advance after weighing phosphorus building gypsum, composite granule and haydite；
