Description
Technical field
The present invention relates to constructional materials,, also relate to the production method of this body of wall in particular to being the materials for wall that raw material is produced with ardealite and polyurethane.
Background technology
Ardealite is the trade waste of Wet-process Phosphoric Acid Production process discharging in the phosphorous chemical industry.In recent years, the technical scheme of ardealite comprehensive utilization continues to bring out, for example No. 95190467.1, Chinese patent application " production method with polymeric material of high chemical resistance and anti-mechanical force ", number 02110236.8 " ardealite wall covering and preparation method thereof ", number 200410021766.4 " with the method for ardealite production building and ornament materials and materials for wall ", number 200410081601.6 " with the section bar and the method for making thereof of ardealite production ", number 200510003008.4 " producing the method for cable or optical cable carriage assembly with polyvinyl chloride resin ", number 200710077929.4 " a kind of mine main substitutes the method for mine timber " etc.
Aspect building construction, people have the constructional materials of insulating power in exploration, many patent applications have also appearred, for example No. 200410024676.0 " polyurethane foam one-shot forming heat-insulation wall plate and manufacture craft thereof ", No. 200610107915.8 " method for manufacturing Rigid foam polyurethane heat-preserving system ", No. 200610166299.3 " a kind of pouring polyurethane heat insulating wall ", No. 200610018144.5 " hard polyurethane foam board composite energy-saving wall and construction technologies thereof " etc.
In recent years, along with China's energy-saving and emission-reduction, improve the execution of environmental policy, the development constructional materials especially is incubated, heat insulation materials for wall heats up gradually.Still the discarded object ardealite of no-trump phosphorous chemical industry and the polyurethane information of making raw material production lightweight, insulating wall material is seen in report, does not also have relevant patent application yet up to now.
Summary of the invention
The object of the present invention is to provide a kind of light insulating wall, it is produced with polyurethane and ardealite, for a new approach is opened up in the utilization of ardealite.
Another purpose of the present invention is to provide the production method of this light insulating wall.
The light insulating wall that the inventor provides is with two-layer modified ardealite Cement fibre composite plate, the sandwich sheet material that middle injection polyurethane foam is made.
The edge, the left and right sides of above-mentioned sandwich sheet material all has tenon, Yi Bian be positive tenon, Yi Bian be cloudy tenon.
The concrete grammar of production inventor's light insulating wall is as follows:
The first step is carried out the modification of ardealite
Elder generation cleans up ardealite and dries with clear water, deliver to the tunnel cave high-temperature calcination, deviates from part moisture, P in the ardealite
2O
5And fluorine, make its water content be lower than 10%, P
2O
5≤ 0.3%, F≤0.1%; To send into the grinding machine abrasive dust through the ardealite after the calcining again, standby;
In second step, make the phosphogypsum high-strength cement fibrolite plate
Modified ardealite, cement, fortifying fibre are put into mixer with an amount of water in proportion stir, the material that will be mixed is then sent into prefabricated mould, and through the typing of roll extrusion for the first time, the leveling of roll extrusion for the second time is compacted into highdensity ardealite cement fiberboard; Afterwards plate is taken out, be placed on the outdoor maintenance frame and maintain; Take out the ardealite cement fiberboard after maintenance is finished and had high strength, be cut into required specification;
In the 3rd step, the combination of preparation polyurethane foam is expected
Mix in mixer according to formula rate, enter foaming machine then and mix, promptly make the polyurethane foam combination and expect, be used for next step immediately with the MDI high-speed stirred;
The 4th step, inject polyurethane foam, make sandwich wall board
With phosphogypsum high-strength Cement fibre grillage in prefabricated body of wall mould the inside, with injector the polyurethane foam combination of previous step preparation is expected to throw into mould again, make it curing molding, then mould is opened, make the sandwich assembling wall body of high strength ardealite cement fiberboard polyurethane foam.
In the above-mentioned first step, described high-temperature calcination is to calcine 20～30 minutes down at 1300～1360 ℃, the grinding machine of described abrasive dust is ball mill or Raymond mill, fineness of grinding is determined according to product needed, is generally 400～1000 orders, and is high if toughness of products requires, then more levigate, can reach 800～1200 orders, if cement fibrolite plate, then 400～500 orders get final product.In order to guarantee that ardealite is clean relatively, tunnel cave adopts gas fuel combustion, for example with common town gas, natural gas, water-gas or semiwater gas, purify yellow phosphorus electric furnace tail gas, calcium carbide stove exhaust etc. after filtration and make fuel, but can not make fuel with coal dust.
In above-mentioned second step, the ratio of described ardealite, cement, fortifying fibre is 6: 3: 1; Described mixing mixing time is 15 minutes; The described sheet material service time that makes is 28 days.
In above-mentioned the 3rd step, the prescription that described polyurethane foam combination is expected by the quality proportioning normally
100 parts of KX/ZHL201 combined polyethers
20～23.5 parts of fire retardants
29.5 parts of HCFC-141b blowing agents
180～184 parts of isocyanates MDI;
Described mixing time is 10s, and in the described foaming process, cream time is 15～60s, and gel time is 90～180s, not sticking time 120～240s.
The combinations thereof polyethers is known product of forming, having certain stability by auxiliary agents such as PPG and catalyzer, foam stabiliser, blowing agent, fire retardants.
Used fire retardant is known antimony series, boron series or halogen series or phosphoric acid ester fire retardant in the above-mentioned prescription.
In above-mentioned the 4th step, the time of described curing molding is 30 minutes.
Light insulating wall mounting method of the present invention is that upper groove, low groove that modified ardealite forms a complete production network are separately fixed at the upper and lower position of the concrete frame that has built up, the wallboard of packing into afterwards allows the moon button of the sun button of a back wallboard and last block of wallboard fasten mutually to form whole.
This light insulating wall have lightweight, good weatherability, corrosion resistance strong, bright and clean attractive in appearance, do not fire, advantage such as intensity height, cost are low, easy installation; Can alleviate the gross weight of whole building, the usable floor area in increase house.Use the inventive method, both can reduce the pollution of ardealite effectively, help improving environment environment, turn harm into good, improved the construction speed of building again, reduced the cost of building, have good society and environmental effect, good economic benefit is arranged again.
