Description
One, technical field
The present invention is a kind of rhombspar magnesium cement inner, external wall fireproof decoration plate and method of manufacture thereof, belongs to the chemical building material field.
Two, background technology
Magnesite PLASTIC LAMINATED decorative sheet with good performance such as fire prevention, high-strength light, anticorrosion, to be prone to characteristics such as construction widely-used at building materials field; At present; Main raw material light burnt powder (magnesia) place of production that produces magnesite PLASTIC LAMINATED decorative sheet goods mainly concentrates on China Liaoning; Limited by the resource region, it is higher to produce magnesite PLASTIC LAMINATED decorative sheet raw materials cost, is difficult for promoting.
Three, summary of the invention
The present invention is that (it is that lime carbonate and magnesiumcarbonate double salt are the ore of staple, and molecular formula is CaMg (CO with dolomite mineral
3)
2) the caustic dolomite powder and the magnesium chloride that obtain after the roasting be main raw material, through mixing operations such as slurry, forming and hardening, maintenance, makes rhombspar magnesium cement inner, external wall fireproof decoration plate.The present invention intends the technical scheme of taking: a kind of rhombspar magnesium cement inner, external wall fireproof decoration plate and method of manufacture thereof; It is characterized in that rhombspar magnesium cement inner, external wall fireproof decoration plate is made up of caustic dolomite powder, magnesium chloride, light filler, inert packing, water and lagging material; Its mass ratio is 1.00: 0.12～0.40: 0.10～0.60: 0.05～0.30: 0.44～1.20: 0.05～0.30; The middle an amount of supporting material that adds; Supporting material is middle alkali glass silk cloth, non-woven fabrics; Light filler is sawdust or straw shell or agricultural crop straw powder or its mixture, and inert packing is flyash or talcum powder or slag powders or its mixture, and lagging material is pearlstone or expanded vermiculite or organic polymer or its mixture; Its method of manufacture is for mixing slurry → forming and hardening → maintenance; The processing requirement of mixing slurry is formation magnesium chloride solution that magnesium chloride is dissolved in the water in proportion, and magnesium chloride solution and caustic dolomite powder, light filler, inert material, the pro rata mixture of lagging material carry out mix, form caustic dolomite magnesium cement slurry; The processing requirement of forming and hardening is that above-mentioned caustic dolomite magnesium cement slurry is injected laminator or particular manufacturing craft; An amount of supporting material is put in the shop, solidifies the demoulding after 18～24 hours, the processing requirement of maintenance be after the demoulding 10～40 ℃, relative air humidity less than 80% condition under indoor maintenance greater than 28 days.Magnesium chloride can use the hydrate of magnesium chloride to substitute among the present invention.The present invention realizes like this; At first the hydrate water with magnesium chloride or magnesium chloride is mixed with solution; Become uniform slurry with the mixture mix of caustic dolomite powder, light filler, inert material and lagging material then; Slurry injects laminator or particular manufacturing craft forming and hardening, and maintenance after the demoulding, maintenance are accomplished and be product.The present invention proposes to adopt the caustic dolomite powder to make the inner, external wall fireproof decoration plate, and the dolomite mineral resource then distributes extensively, and almost national each province all has; Reserves are abundanter; Make full use of the rhombspar resource, locally draw materials, will reduce the cost of producing this product; Expand the application of magnesium cement material, have great importance for development various places economy and China practice thrift timber in a large number.Adopt the inner, external wall fireproof decoration plate for building that the present invention produced; Have fire prevention, insulation, intensity height, water-tolerant, anticorrosion, shockproof, easy construction, environmental protection and energy saving; And production technique is simple, and low power consumption and other advantages is to substitute sheet material renewal products such as various wood veneers, density board, shaving board, Thistle board; Belong to green structural material, can be widely used in construction industry.
