Abstract

The present invention relates to an inorganic nonflammable composite plate and a making method thereof, which belongs to the field of magnesium oxychloride cement. The inorganic nonflammable composite plate is made from 90 to 120 portions of light calcined magnesia (the content of MgO is at least 80%), 75 to 100 portions of magnesium chloride water solution (the baume degree is 22 to 28Be DEG), 5 to 25 portions of filling agents, 3 to 5 portions of water-resistant additives and 5 to 10 portions of toughening agents. Owing to the addition of the water-resistant additives, the five-phase structure is stabilized, and meanwhile, water-insoluble magnesium phosphate is produced so as to improve the water resistance of the magnesium oxychloride cement material in nature. The toughening agents have the function of enhancing the holding force. The inorganic nonflammable composite plate provided by the present invention is suitable for mechanical forming; the content of solid in slurry is from 50 to 60 wt%. The present invention solves the defects of easy bittern formation, warping deformation, poor water resistance, etc. existing in the traditional magnesium cement products.

Description

A kind of inorganic non-combustible type composition board
The present invention relates to a kind of inorganic non-combustible type composition board (MP plate), belong to the magnesia oxychloride cement field.
Magnesia oxychloride cement have that sclerosis is fast, intensity is high, flexible, fire resistance is good and with advantages such as the compatibility of many sound and thermal insulating materials is good.Yet its solubility in water has but limited its range of application greatly.For a long time, domestic and international many scholars all are devoted to improve the water resisting property research of magnesia oxychloride cement, obtained certain progress, but failing essence solves, the contriver of Chinese patent CN1070175A (publication number), attempting to provide a kind of is raw material with light calcined magnesia and magnesium chloride, the fusion additive, auxiliary materials such as weighting material are made heat-insulating decorative board in order to replace three-ply wood, five-layer plywood, plank is used for revetment, furred ceiling, fire door, furniture panel etc., it is 30.4MPa that its product detects folding strength through relevant department, and water tolerance was only boiled in boiling water 2 hours or 50 hours outward appearance no changes of cold water soak.Obvious its water resisting property etc. fails to obtain satisfied progress; Chinese patent CN2240526Y provides magnesium oxychloride glass fibre reinforced cement dull and stereotyped production equipment, although can raise the efficiency 5 times, the product surface of producing is smooth, and it is remarkable to install this body structure, and production cost can improve on the contrary.
From the knowledge that has accumulated, the main hydration products under the normal temperature after the oxychloride cement sclerosis is 5Mg (OH) 2MgCl 28H 2O (being called for short 5 phases) and 3Mg (OH) 2MgCl 28H 2O (being called for short 3 phases).Studies show that 5 are to magnesia oxychloride cement sclerosis mutually and produce the phase that intensity plays main contribution, 5 can be converted into 3 phases mutually under certain condition, thereby at MgO-MgCl 2-H 2In the O system, 5 phases that generating structure is stable are avoided the existence of 3 phases, suppress 5 conversions of 3 phases in opposite directions as far as possible, must strictness control MgCl in component 2Content, and make have in the system some amount like gelatinous Mg (OH) 2Exist.Moreover, stablize 5 except that structure during the composition board that is preferably in fire-retardant type is formed and exist mutually and can also form part water resisting property water cenotype, thereby solve the weakness of the water resisting property difference of magnesia oxychloride cement in essence, simple as far as possible in manufacturing processed simultaneously, practicality, inexpensive.
The objective of the invention is to by strictness control MgCL 2Total content and a kind of novel inorganic flame-retardant type composite slab of composition that adds anti-water additive and toughner.
The present invention implements by the following technical programs.The raw material weight component of novel inorganic flame-retardant type composite slab (MP plate) is: light calcined magnesia (MgO content 〉=80%) 90-120 part, magnesium chloride brine (degree Beaume is 22-28Be °) 75-100 part, stopping composition 5-25 part, anti-water additive is 3-5 part, toughner 5-10 part, wherein weighting agent can be a kind of, two kinds or the three kinds of compositions in talcum powder, wood sawdust, wollastonite powder, the expanded pearlite powder; The active 10-15 of light calcined magnesia (iodine adsorption number).Anti-water additive and toughner are two major technique features that the present invention is different from other inventions, and anti-water additive is made up of phosphoric acid and monovalence to tervalent phosphoric acid salt.Its proportioning is 1:(0.5～0.8) (weight ratio), phosphoric acid salt can be sodium phosphate, aluminum phosphate, trimagnesium phosphate, potassiumphosphate, tertiary iron phosphate.Toughner be by a kind of in commercially available acrylic emulsions, 307 resins, 191 resins or two kinds formulated.The effect one of anti-water additive be stablize 5 phase structures, make it to grow stable; The 2nd, in component, generate water-fast trimagnesium phosphate-Mg 2P 2O 7(its X diffractive features falls d=3.030,2.975,4.140) thus from improving the water resisting property of magnesia oxychloride cement material in essence, the effect of toughner is to improve the toughness of composite sheet, promptly improves its gripping force.
The mechanical-moulded property of inorganic non-combustible type composition board provided by the invention (MP plate) is good, manufacturing process is simple, concrete grammar is that the template with resistant to elevated temperatures (120 ℃) is placed on the shaper machinery and lays two layers of glass cloth (each one deck up and down), it in the middle of two layers of non-woven fabrics (each one deck up and down) the anti-water magnesium cement slurry (slurry that is made into by above-mentioned composition, see embodiment for details), its solid content is 50-60% (wt), through three continuously extruded shapings, the demoulding after placing 24 hours on the template, (decided in maintenance 10-20 days then on temperature, the corresponding minimizing of the high curing time of temperature) used glass cloth is No. 2 commercially available medium-alkali glass fiber cloth, non-woven fabrics is commercially available, and specification is 10-30 gram/M 2
A kind of flame-retardant type composite slab provided by the invention can be used as a kind of novel decorative, fire prevention, building board and furniture surfacing material, as house furred ceiling, interior wall dividing plate, wall dunnage, fire door and kitchen furniture, it has solved the easy general halogen buckling deformation of traditional magnesium cement, deadly defects such as water resisting property difference have enough high strength, good water resisting property, in light weight, low price, are convenient to advantages such as mechanical-moulded.
