Description
One, technical field
The present invention is a kind of lightweight rhombspar magnesium cement block and unburned steaming brick and manufacture method thereof, belongs to the chemical building field
Two, background technology
The building block of domestic present use or brick have materials such as flyash, slag, clay, silicate to make.Flyash or slag building block, it is low to exist intensity, poor water resistance; It is big that silicates exists capacity, and soundproof effect is poor; The clay building block is big to environmental destruction, and genus bans use of.Magnesite building block and unburned steaming brick are with good performance such as fire prevention, high-strength light, insulation, sound insulation, easily characteristics such as construction are widely-used at building materials field, at present, main raw material light burnt powder (magnesia) place of production that produces magnesite building block and unburned steaming brick mainly concentrates on China Liaoning, limited by the resource region, it is higher to produce magnesite building block and unburned steaming brick 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 main component, and molecular formula is CaMg (CO with dolomite mineral
3)
2), caustic dolomite powder that obtains after roasting and magnesium chloride are main raw material, by mixing slurry, forming and hardening, operations such as maintenance are made lightweight rhombspar magnesium cement block and unburned steaming brick, the technical scheme that the present invention intends taking is: a kind of lightweight rhombspar magnesium cement block and unburned steaming brick are inhaled its manufacture method, it is characterized in that lightweight rhombspar magnesium cement block and unburned steaming brick are by the caustic dolomite powder, magnesium chloride, light filler, inert filler, water and lagging material are formed, its mass ratio is 1.00: 0.25～0.40: 0.50～1.0: 0.05～0.30: 0.60～1.20: 0.10～0.50, light filler is sawdust or straw (shell) or agricultural crop straw powder etc. or its mixture, inert filler is flyash or slag powders or talcum powder or its mixture, lagging material is pearlstone or expanded vermiculite or organic polymer or its mixture, its manufacture method is for mixing slurry → moulding → maintenance, the processing requirement of mixing slurry is magnesium chloride solution and caustic dolomite powder, light filler, inert filler, the pro rata mixture of lagging material carries out mix, form slip, the processing requirement of moulding is that above-mentioned slurry is injected block-making machine or brick press, the compacting back demoulding, it is in envrionment temperature after the demoulding that the maintaining process of building block requires, relative air humidity is product after 28 days less than maintenance under 80% condition, it is maintenance 0.5～2.0 hour in the pressurized tank (or cabinet) of 105～140 ℃ of steams that the maintaining process that steams brick requires, maintenance 28 days at ambient temperature can be finished product after offeing for sale.Magnesium chloride can substitute with the hydrate of magnesium chloride 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 in proportion, become uniform slurry with the mixture mix of the lagging material of caustic dolomite powder, light filler, inert filler then, slurry injects brick press or particular manufacturing craft compression moulding, maintenance after the demoulding, maintenance are finished and are product.The present invention proposes to adopt activity caustic dolomite powder manufacturing building block preferably and unburned steaming brick, the dolomite mineral resource is then widely distributed, 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 save timber in a large number.The light block and the unburned steaming brick that adopt manufacture method of the present invention to produce, have characteristics such as fire prevention, insulation, intensity height, sound insulation, anticorrosion, shockproof, easy construction, environmental protection and energy saving, be to substitute the building block that various traditional materials make and the renewal product of brick, belong to green structural material, can be widely used in construction industry.
