Abstract
A kind of magnesite concrete composite slab and forming method thereof, use adhesive magnesite concrete concrete and additive thereof on the carrier attached to the braiding soft seat, this method can produce big, the thin magnesite concrete composite slab of area, bigger, in light weight than the simple timber intensity of making of the magnesite concrete, improved the performance of shock resistance, counter-bending, anti-vibration, and moulding process is simple, cost is low, is a kind of comparatively ideal generation wood products.
Description
The present invention relates to a kind of magnesite concrete composite slab and forming method thereof, this sheet material can replace the various packaging boxboards of producing wood, bed board, dividing plate etc.
The product of a kind of " water-resistant magnesia cement " is disclosed in CN87107780A, disclose a kind of " magnesia clay constituent and plate forming method " and Australian Ausmintec Corp. Ltd. (AU) State of South Australia Commonwealth of Australia disclose a kind of " magnesium cement " in CN87100032A product in CN86104319A, their purpose is emphatically to solve water repelling property and the intensity that strengthens magnesium cement and magnesia clay constituent and simplify production technology.In magnesium cement and magnesia clay thing, add water-resistance additive or other compound composition, moulding in mould of plastics, under higher temperature the reaction formed magnesium cement products, basically solved magnesium cement, magnesia clay thing water repelling property is low, the problem that intensity sharply descends under the effect of water, and improved manufacturing process.But it is bigger to be to use simple magnesium oxychloride concrete to make area, shortcomings such as thin sheet material exists lower, the easy crack of intensity, easily pokes, flexible, distortion, and the construction material weight of making, volume also seem heavier, bigger.
The objective of the invention is still to use magnesium oxychloride concrete material cheap and easy to get for mainly make big, the thin sheet material of a kind of area, guarantee required intensity, not flexible, distortion, crack not, the volume of the construction material of making, weight also reduce relatively, and manufacturing process is simple, easily grasp.
The scheme that realizes the object of the invention is: make magnesite concrete concrete attached on the carrier, this carrier is the braiding soft seat, and is bonding with the braiding soft seat magnesite concrete concrete with adhesive.Forming method is: be coated with one deck adhesive on the one side of braiding soft seat, cover one deck magnesite concrete above the adhesive and mix earth and additive thereof, mix covering one deck adhesive and braiding soft seat on earth and the additive successively again at the magnesite concrete; Perhaps on the positive and negative of braiding soft seat, all coat on adhesive, the positive and negative adhesive and all cover magnesite concrete concrete and additive thereof; Perhaps on the one side of braiding soft seat, be coated with one deck adhesive, cover one deck magnesite concrete concrete and additive thereof above the adhesive.Can coat ornament materials above the braiding soft seat of the various composite boards of moulding.
Below engaging embodiment further illustrates the solution of the present invention.
Accompanying drawing is the structural representation of magnesite concrete composite slab of the present invention:
Among the figure: (1) is the braiding soft seat, and (2) are adhesives, and (3) are magnesite concrete concrete, and (4) are that second layer adhesive, (5) are second braiding soft seats, and (6) are ornament materials, and (7) are frameworks.(8) be the muscle material, (9) water-resistance is dosed thing.Described braiding soft seat (1), (5) are the soft seats that bamboo mat, reed mat or fiber pole stock are weaved into.
Described magnesite concrete concrete is by MgO(magnesia), MgCl
2(magnesium chloride) and filler are formed, and their mixing ratio is:
100 parts of MgO
MgCl
2100-120 part
Filler 50-80 part
Filler can be the crushed material of various fibers such as sawdust, straw, wheat straw, Chinese ephedra grass, also can add a certain proportion of talcum powder and land plaster.
Described adhesive (2) (4) is the aqueous solution of magnesia and magnesium chloride, and the prescription of the aqueous solution is MgO 40-60 part, MCl
260-40 part, MCl
2The concentration of the aqueous solution is 24B '-32B ' (Baume degrees).
Described waterproofing agent is:
The commercially available patent of invention product P W-1 of Chinese Academy of Sciences type additive.
Described muscle material is: bamboo reinforcement, splendid achnatherum bar, reed bar and other fiber rod.
Described ornament materials is: gypsum, fiberglass lacquer, woodgrained paper, various wallpaper, coating, paint vehicle etc.
During making, do a framework (7) according to the size of required sheet material, framework (7) available metal, timber and fibrous plate or plastic production, cloth muscle material (8) in length and breadth in wooden frame (7), in the eyelet on muscle material (8) the termination insertion framework (7); Cutting the bamboo mat sheet according to the required size size is bamboo mat (1), bamboo mat (1) is placed on the plane, bamboo mat (1) is preferably in the water and soaked about 1 hour before using, on bamboo mat (1), be coated with magnesium chloride and the magnesian aqueous solution of one deck as adhesive, magnesium chloride and magnesian aqueous solution preparation method are as previously mentioned, then the framework that is furnished with muscle material (8) (7) is placed on the bamboo mat (1) that scribbles adhesive (2), magnesite concrete concrete (3) is dosed in framework (7); Add PW-1 type water proofing property in the magnesite concrete concrete (3) and dose thing (9), magnesite concrete concrete (3) is constantly filled evenly and compacting, makes surfacing smooth; Also can on the smooth magnesite concrete concrete (3) of surfacing, be coated with second layer adhesive (4) again, on adhesive (4), cover second layer braiding soft seat (5) again, the composite board of this increase one deck braiding soft seat structure is than the more not yielding of one deck braiding soft seat structure only arranged, be fit to do the interlayer board of bed board, furniture, various packaging boxboard, what have one deck braiding soft seat is fit to do clip board and light-duty packaging boxboard; Also can all be coated with last layer adhesive (2) on one deck weaves the positive and negative of soft seat (1), the two sides all has magnesite concrete concrete and additive (3) to cover on the adhesive (2).Can coat various aforesaid ornament materials (6) according to various needs on the braiding soft seat (1) of every kind of composite board of above-mentioned moulding.
This magnesite concrete composite slab is in the mode of bamboo, soil and bamboo, soil, wooden combination, make a kind of brand-new for wood products, big, the shortcomings such as intensity is low, mutability is bent, distortion of weight of using simple magnesite concrete to mix the sheet material existence of earth making have for a long time been solved, make clip board with this sheet material of the present invention, its compression strength is 4 times of wooden splint, and have attractive appearance, thickness evenly, consistent size, and paper there is not any damage, and cost is low, be (40-60) % of wooden clip board cost, and recyclable, market prospects are very wide.Can make packing case of all sizes with this composite board, purposes is more extensive.Its intensity is big, has certain elasticity, and the performance of shock resistance, counter-bending, anti-vibration is in light weight, is 50% of whole magnesite concrete material package component weight, and cost is low, every m
2About 3 yuan of valencys, be the 1/5-1/8 of bamboo plywood, this sheet material is not afraid of and is damaged by worms, acid and alkali-resistance, moistureproof water-tight, rational in infrastructure, distortion is little, easy to assembly, long service life.This composite board also can be made bed board, various furniture dividing plate, kitchen internal partition, but also Manufacture of Floor brick and decorative wall panels etc.The moulding process of this composite board is very simple in addition, does not need what special main equipment to make.
