Abstract
The magnesium-silicon plant fiber composite light hollow wall board is prepared by compounding magnesite, industrial waste residues (including waste residues with high silicon content such as fly ash, steel slag and slag), glass fibers, plant fibers (including sawdust, wheat straw, cotton straw, corn straw, rice hull, bean straw, hemp straw and the like), magnesium chloride, additives and the like at normal temperature and normal pressure. The product specification is 2400-3400 mm in length, 600-1200 mm in width and 60-120 mm in thickness, and the center of the plate is evacuated by adopting multiple holes. The wall board has the characteristics of light weight, high strength, flame retardance, heat insulation, good water resistance and convenience in installation and construction, and can be used for occasions such as frame structure infilled walls, movable house walls, roofs and the like.
Description
The present invention relates to a kind of non-bearing lightweight wallboard, its unit weight is 500～800kg/m.
The magnesia goods are so that its production technology is simple, with low cost, intensity is high, the advantage of good springiness has obtained and used (for example wood floor bolck, thistle tile, bathtub, pipeline etc.) widely.But, limited its use again in many occasions because the refractoriness of magnesia goods is poor, easily return frost, shortcoming such as yielding.Over nearly two, 30 years both at home and abroad the scientific worker carried out a large amount of scientific researches at the weakness of magnesia, and many organic matters and the inorganic matter modifier (for example Lauxite, zinc chloride, sulfate, phosphate etc.) as the magnesia goods has been proposed.
The industry that the objective of the invention is to contain by adding activated silica is that slag (for example flyash, slag, slag etc.) improves weakness such as magnesia poor water resistance, reduces unit weight and improves heat insulation performance by adding agricultural wastes (as sawdust, straw, cornstalk, rice bar, rice husk, beanstalk, waste of flax etc.) such as string; Improve intensity by adding glass fiber; Additional a small amount of to magnesia modification and the useful additive of intensity, make frame structure building with partition board (claiming infilled wall again), this wallboard also can be used for the roofing and the metope of booth, mobile house.
Manufacture craft characteristics of the present invention are to adopt normal temperature, normal pressure moulding, technology is simple, energy consumption is low, the plate center adopts porous to find time, and evacuation rate is 18～40%, with the weight of lightened plate floor and save material; Two of plate adopt on long limits mould moldings to go out flange and groove, are convenient to construct between plate and the plate be connected.
The raw material that the present invention selects for use are respectively: magnesia or light calcined magnesia, and its content of magnesia should be greater than 70%; Industrial residue should be the higher industrial residue of silicon content, as flyash, and slag, slag etc., industrial residue needs levigate, and fineness requirement is 170 orders; Glass fiber adopts glass fabric, glass fiber mesh, and glass fiber, opening silk all can; String comprises sawdust, straw, cotton stalk, cornstalk, rice bar, rice husk, beanstalk, waste of flax etc., and it should be crushed in advance length is 1～5mm; Magnesia is industrial hex-ammoniate, halogen sheet or enriched bittern cake; Additive is divided into three kinds: A, phosphoric acid and phosphoric acid salt, and as sodium phosphate, magnesium phosphate.B, silicate of soda, prodan.C, formaldehyde polyvinyl acetal claim 107 glue again.
Various material weight proportioning of the present invention is as follows:
Magnesia 30～70%
Industrial residue 10～45%
String 7～35%
Glass fiber 0.5～5%
Magnesium chloride 10～20%
Additive A 0.02～2%
Additive B 0.5～2%
Addition of C 1～5%
Technological process of the present invention is as follows:
In advance with industrial residue grinding to 170 order; Plant stalk powder is broken to 3～10 millimeters; Magnesium chloride is mixed with 20～30 Baume degrees aqueous solution and additive is dissolved in wherein.Magnesia, industrial residue, string are placed in the mixer and mix, add the magnesium chloride and the additive aqueous solution that prepare, continue to be stirred to evenly.Bottom surface layer is mated formation then, and glass fiber is mated formation, and the stamen layer is mated formation, vibration moulding, and the stamen pipe is extracted in the upper layer leveling of mating formation out.(mat formation and vibro-moulding process also can adopt the special-purpose machinery one-shot forming, this moment, glass fiber need adopt short glass fiber, and length is 3～10 millimeters, and siccatives such as glass fiber and magnesia are pre-mixed) natural conditions maintenance.
The magnesium silicon fiber-setting composite lightweight wall plate basic mechanical design feature index that adopts the present invention to make is as follows:
Project unit's index
Thistle board unit weight kg/m 500～700
Thistle board load 2000N flawless
Shock resistance 150N sand pocket flawless
Impact 100 times
Coefficient of softening % is greater than 0.8
Coefficient of thermal conductivity W/MK 0.17
1 grade of fire resistance horizontal firing method
The Light trabs that the present invention adopts part industrial residue and part agricultural wastes to produce, have that unit weight is little, intensity is high, water-fast, fire-retardant, heat insulation, can follow closely, can saw, can dig, construction install convenience, product surface is smooth, can utilize to comprise that wallpaper and various coating characteristics such as decorates.Roofing, the metope the present invention that can be widely used in mobile house such as the infilled wall of frame structure building and booth adopt normal temperature, normal pressure moulding, production technology is simple and utilize industrial residue and agricultural wastes, therefore can save a large amount of energy and make product cost be lower than similar Light trabs.
Accompanying drawing is the external form schematic diagram of light hollow wall plate of the present invention.
Be illustrated below in conjunction with examples Example:
Example 1, with magnesia 24kg, flyash 12kg, milled powders of cornstalk particle 7kg, sodium phosphate 0.04kg, 107 glue 0.5kg, water 25kg stirs, and mould is put in order, getting 1/10 of above-mentioned compound is tiled in the mould, shop layer of glass net is laid on 8/10 of compound in the mould, spreads a layer glass fiber mesh, vibrator vibration two minutes, remaining compound is mated formation on the top layer and, extract the stamen pipe out, natural curing 24 hours with the scraper plate leveling, stack normal temperature cure 7 days for edge-on, the Light trabs unit weight of 2600 * 600 * 60mm that makes is 597kg/m
