Abstract

" PSC " modified chloromagnesite sheet product belongs to the New Building Materials field.

The present invention selects for use flyash, light-burning magnesium powder, magnesium chloride solution and PSC admixture to form.The PSC admixture is organic and inorganic polymkeric substance, through chemical reaction, generates the Magnesium Silicate q-agent material of the hydraulicity.This plate has light weight, high-strength, water-fast, fire-resistant, indeformable, the characteristics that can follow closely, can saw, can dig.Can make flush door, furniture, thermal insulation moveable house plate, circular hole or atresia partition plate.This plate is compared with the magnesite plate, and the magnesite plate soaks half a year intensity and has only 11% of former intensity in water, and the PSC plate soaks half a year in water, intensity reaches former intensity 98%, the character instability of magnesite plate is made moist and is returned the halogen buckling deformation, and the PSC plate does not exist the distortion warpage to return the tooth phenomenon.

Description

Modified chloromagnesite sheet product

The invention provides a kind of New Building Materials, " PSC " modified chloromagnesite sheet product is called for short " PSC " plate." PSC " board raw material composition: (1), be catch settled flyash to receive in the thermal power plant boiler flue accounts for total composition 40%.(2), light-burning magnesium powder accounts for 25%.(3), magnesium chloride brine (20 ℃ of degree Beaume) accounts for 20%.(4), " PSC " admixture accounts for 15%.The chemistry reflection behind the slip of furnishing pasty state, takes place in above polymerizable raw material together, is put on above the woven fiber glass, or is sprayed on the woven fiber glass, solidifies the Magnesium Silicate q-agent material that the back generates the hydraulicity.Through spraying, cold pressing, but three kinds of processing methodes of cast are with regard to shape sheet material.

This plate has light weight, high-strength, water-fast, indeformable, the characteristics that can follow closely, can saw, can dig.PSC plate purposes is very extensive, and the thin plate of 2-3mm can be made into the plate face of flush door, antitheft door.Replace traditional three-ply-wood or fiberboard, steel plate.Also can be made into kitchen furniture, hanging cupboard, replacement medium-density plate or shaving board.Simultaneously also can be compound with polyphenyl, be made into thermal insulating composite panel, be used for body of wall, exterior wall internal insulation, cut off wallboard.Also can make thermal insulation moveable house and balcony door central layer, replace magnesite polyphenyl composition board.

PSC plate and other sheet material relatively have many good qualities:

To compare unit weight light with plasterboard, plasterboard unit weight 900kg/m ³, and PSC plate unit weight 500kg/m ³Water resisting property is strong, and waterproof gypsum board also is unable to undergo the immersion of 24h in water, remains unchanged and the PSC plate soaks three months intensity in water.Compare with the magnesite plate, the magnesite plate soaks half a year intensity and has only 11% of former intensity in water.And the PSC plate soaks half a year in water, and intensity reaches former intensity 94%.The character of magnesite plate is extremely unstable, makes moist and returns the halogen buckling deformation.And the PSC plate is indeformable, can make 2 meters long, one meter wide, thin plate that 2mm is thick and use separately.Do not exist the distortion warpage to return the halogen phenomenon.

" PSC " board raw material formula rate is pressed 100 parts of calculating:

40 parts in flyash (containing silicon-dioxide more than 50%, fineness R80 screen over-size 7.6%)

25 parts of light-burning magnesium powders (magnesium content is more than 85%)

20 parts of magnesium chloride solutions (20 ℃ of degree Beaume)

15 parts of " PSC " admixtures

" PSC " admixture is made up of phosphoric acid, ferrous sulfate, calcium oxide, Vinyl Acetate Copolymer.

" PSC " admixture weight is calculated by 100%.

Wherein phosphoric acid accounts for 30%, and ferrous sulfate accounts for 5%, calcium oxide 45%, Vinyl Acetate Copolymer 20%(solid content 50%).

The manufacture craft of " PSC " plate: A, gunite; B, cold press process; C, casting.More than three kinds of technologies, different technology can be produced difform product.

A, spray technology

Adopt screw mortar squirt pump, the LSB-1.2 type, the Weihe River, Henan city Construction Machinery Plant produces.The spray technology parameter is as follows:

Emitted dose (1/min) 5-20 spraying pressure (MPa) 5

The supporting power of speed range (rP.m) 40-200 (KW) 1.5

Mix up slip by above-mentioned prescription and pack in the pump, select plastic mould for use, spread mold oil above the template, woven fiber glass is tiled on the template, with spray gun directly toward woven fiber glass above material spray starch, as the plate of need 2mm thickness, when having sprayed the first layer woven fiber glass, add one deck woven fiber glass again, the thickness of every increase 1mm just added one deck woven fiber glass, through chemistry reflection in 4-8 hour, the demoulding of just can hardening just forms sheet material after the deburring.

B, cold-press process

Cold-press process is to be used for making 10-60mmPSC hollow shelf or warming plate, the plate face and the furniture of various door-plates (flush door, antitheft door), and this method of colding pressing is once shaped.

Making method is placed on one with plastic mould and spreads mold oil above the platform, and woven fiber glass is tiled on the template, and slip is prepared by above-mentioned prescription, is poured on above the woven fiber glass floating.At this moment the wooden frame shelf is placed on above the template of smearing slurry the thickness of the thickness decision plate finished product of wooden frame shelf.Filling in polyphenyl or fluting board grid (seeing accompanying drawing one) in the wooden frame gets another piece plastic mould and uses with quadrat method shop woven fiber glass, floating slip, with sandwich polyphenyl or fluting board grid in the middle of next closes on two templates, send to pressurization, after solidifying in 4-8 hour, one up and down, sandwich polyphenylene heat insulation slab in deburring just forms, the hollow flush door (seeing technical process accompanying drawing three) of interior sandwich fluting board, but the method applying pressure machine of pressurization, also available indigenous method is after bolster lumps together, put a big plate pressurization above, simultaneously the way pressurization of linking closely with the screw mandrel screw.Pressure is not less than 1 ton pressure.

C, pouring technology

The PSC plate mainly is to produce hollow partition board or light cellular partition board with watering column method.Modern high-rise building need be with a large amount of partition plates, and it is little to require to have unit weight, the intensity height, shock resistance, sound insulation, heat insulation, performance such as do not fire, in order to process and to install and requiring it can follow closely, can dig, can saw, the PSC plate is made partition plate and is divided into abacus and two kinds of shapes of atresia thistle board.Making method selects for use the 60mm angle bar to do the mould limit, puts a plastic plate on platform, and it is good that angle bar is pressed the specification sign indicating number.Circular hole is left on two limits, inserts round steel pipe, and the PSC material will prepare by above-mentioned prescription, be cast in the core rod through 4-8 hour with regard to the solidifiable demoulding, extract steel pipe out and add and be formed with hole circle orifice plate (seeing Figure of description two).Do not put into steel pipe in the core rod, put into the light material polyphenyl, perlite is filled out core, can form the atresia light cellular partition board.
