Abstract
An ordinary-temp solidifying agent for preparing building materials is prepared from activated magnesium oxide (35-62 wt.%), magnesium chloride (30-55%), plastic material (2-12%), water (5-22%), modifier SW (0.08-0.7%) and modifier CW (0.2-0.7%). It can improve the strength of product and increase the content of waste in product. Its advantages are low cost and no need of calcine.
Description
The present invention relates to a kind of material of construction, particularly a kind of solidifying agent of using with waste normal temperature system building materials.
At present, flyash, coal gangue, CHARACTERISTICS OF TAILINGS SAND, antiquated sand (useless sandblast or useless founding or contain the sand of a large amount of soil), riverway sludge, calcium carbide mud, boron mud, red mud, white clay, oil drilling oily sludge, industrial wastewater sludge, city sewage and sludge, engineering roach, mountain root soil, slag, rock ballast (powder), various straw, bagasse, furfural dregs, vinasse, useless vegetable fibre, waste incineration resistates and (polyphenyl or polyester) depleted porous plastics are well utilized as yet, wherein major part contaminate environment all.At application number is that 98110242.5 denominations of invention are in " mixed crystal contains the building materials that solid waste normal temperature is made " patent application, a kind of building materials of being made up of waste, even toughener and crystallization moderator are disclosed, make waste obtain Preliminary Exploitation, but these building materials still exist the waste amount of filling not high enough, thereby cause the cost height, perhaps waste amount of filling height and intensity is not high, shortcoming such as wet tenacity is very poor, and the life-span is short.
The purpose of this invention is to provide a kind of normal temperature and make the solidifying agent that building materials are used, make the above-mentioned shortcoming that building materials can overcome prior art with it.
A kind of normal temperature is made the solidifying agent that building materials are used, it is characterized in that being made up of 6 components, their weight percentage is respectively activated magnesia 35-62, magnesium chloride 30-55, plasticity-material 2-12, water 5-22, properties-correcting agent SW0.08-0.7, properties-correcting agent CW0.2-0.7.
Solidifying agent of the present invention has SW and CW to participate in, improved the amount of filling that product strength and wet tenacity have improved waste greatly greatly, reduced product cost, eliminated the shortcoming of scumming, the flyash standard brick that promptly uses very high flyash of seawater smoke prevention and dust control, saltiness and solidifying agent of the present invention to make, the phenomenon of also do not return halogen, scum, saltouing takes place.Solidifying agent of the present invention can with gurry mixing normal temperature system building materials, also can with the mixed building materials of general starting material.Production technique is simple, and unburned energy-conservation, cost is low, the intensity height.
Below by example explanation the present invention
Embodiment 1
Take by weighing activated magnesia (having another name called magnesia unslacked), magnesium chloride, plasticity-material clay, water, SW, CW, their weight percentage is respectively 35,52.1,2,10,0.6,0.3.With they mixing and stirring, make solidifying agent of the present invention.The each component of SW of the present invention and weight percentage be respectively: the each component of the phosphoric acid salt 60-65 of sodium, metaphosphate 25-30, oxalic acid 5-10, CW of the present invention and weight percentage thereof are respectively NNOPD20-30, peregal 4-8, sulfuric acid or phosphoric acid 5-10, sodium sulfate 1.5-3 and water 50-70.The phosphoric acid salt 60 that each component of the SW that present embodiment is used and weight percentage thereof are respectively sodium, metaphosphate 30, oxalic acid 10.The each component of the CW that present embodiment is used and weight percentage thereof are respectively NNOPD20, peregal 4, sulfuric acid 5, sodium sulfate 3, water 68.
Get totally 9.1 tons in a kind of flyash and aggregate (aggregate accounts for the 2.5-5% of flyash weight),, shake and press the production standard brick with 0.9 ton of uniform mixing of above-mentioned solidifying agent.Demoulding normal temperature maintenance 28 days.The freeze thawing of gained flyash standard brick is qualified, ultimate compression strength 150-160Kg/cm
2, wet tenacity 130-140Kg/cm
2, cost≤0.08 yuan/piece.
The flyash of present embodiment can change mine tailing sand, coal gangue, antiquated sand, engineering roach, mountain root soil, rock ballast (powder), white, red mud into, but and production blind hole standard square.Wherein plasticity-material clay can be used clay or talcum powder instead, and its effect is identical.
Embodiment 2
Get wheat straw 34kg, add the solidifying agent 66kg that uses among the embodiment 1, stir evenly, make pulp, do stiffening web with moulding net, shaking is pressed into plate, the normal temperature maintenance expire not firebrand fiberboard.1200 ℃ of following no flare of this plate.6mm slab bending resistance failing load 400kg (being higher than standard more than 6 times) also can make the light noninflammable wood-fiber board as required, and they all have uninflammability and nail-holding ability preferably.
Wheat straw in the present embodiment can make straw, forest hay, branch, wood powder, cotton stalk, corn stalk, sorghum rod, papermaking chip etc. into.Can also produce the fp pallet, wrapping material, furniture material.
Embodiment 3
1.8 tons in power taking stone mud, 0.4 ton in slag adopts 1 ton in above-mentioned solidifying agent, and mixing stirs evenly, and the compacting pavement bricks shakes.The normal temperature maintenance is to after date, and ultimate compression strength is 270kg/cm
2, wet tenacity 250kg/cm
2
Calcium carbide mud in the present embodiment can make rock ballast (powder), useless sand, mud, mud, white clay, red mud, boron mud into.Can also produce rivers and canals barrier sheet, tank, revetment brick, terron.
Embodiment 4
Get depleted through pulverized foamed plastic (porous plastics polyphenyl or polyester) 30kg, above-mentioned solidifying agent slurry 70kg, the abundant mixing of the latter's a part and used foam plastics, do the middle layer of fireproof heated board, another part solidifying agent slurry is done surface layer, do stiffening web to mould net, the shaping maintenance can get fireproof heated board.Further handle and can be made into the fireproof heat insulating insulating board.Under the same thickness condition, its insulated capacity is close to the benzene plate, but very easily operates manyly when engineering site uses, and is much better than the purified petroleum benzin plate.
