Description

A kind of fire resisting plate and preparation method thereof containing fluorite ore tailing
Technical field
The invention belongs to fire resisting plate technical fields, and in particular to a kind of fire resisting plate and its system containing fluorite ore tailing Preparation Method.
Background technique
Improvement of living standard, consumer is generally higher and higher to the requirement of living environment, especially firmly row safety.Fire Calamity is inevitable in daily life, we are obvious to all for nocuity.The fire-proof board master that China's construction at present uses Steel, wooden, glass material etc. are used, inevitably there is that some poor high temperature stabilities, to be easy thermally conductive, thermal insulation poor also or anti- The problems such as impact property is poor, intensity is low, higher cost.
It is well known that generate a large amount of fluorite ore tailing in fluorite ore subtractive process, pollution to environment and destroy compared with Greatly, water pollution, land occupation are not only be easy to cause, it is also possible to destroy vegetation, even cause geological disaster.Opposite, if right Fluorite ore tailing is rationally handled, and maximization of economic benefit can not only be pursued, moreover it is possible to effectively improve resource recycling rate and It preserves the ecological environment, therefore, how fluorite ore tailing to be applied in fire-proof board preparation, improve the performance of fire-proof board, ten Divide important.
Chinese patent CN103922691A discloses a kind of magnesia fire-proof plate of slag, belongs to field of material technology.Slag Magnesium of Slag Magnesium Matter fire-proof plate is using magnesium chloride, magnesia as binding material, with slag for main packing material, kaolin, wollastonite and diatomite Mixture be auxiliary packing material, organic and inorganic salt is modified outer permeation, and the mixture of sawdust and reinforcing fiber is strengthening material Material, through being mixed, forms a kind of high-strength fireproof plate by combination reaction after extrusion forming.Slag of the invention is magnesia Fire-proof plate uses industrial slag as packing material, improves the density of plate, and fire-proof plate moisture content and hygroscopicity is effectively reduced, changes It is apt to its resistance to compression and shock resistance, improves the rigidity and flatness of plate；Cost can be effectively reduced simultaneously, greatly improve economy Benefit, but the high-temperature stability of the invention slag coal quality fire-proof plate is general, fire protecting performance is poor.
Chinese patent CN105777156B discloses a kind of using inorganic glue as the light-weight refractory of bonding agent heat preservation vermiculite plate And production method, belong to field of heat insulating materials.Phosphoric acid, aluminium hydroxide, aluminium powder, alumina silicate, water are mixed in a certain ratio first Uniformly, inorganic glue is made under heating condition, after then inorganic glue is added bentonite, is diluted with water, with expanded vermiculite according to certain Ratio carries out ingredient, stirs evenly, mixture is put into mold, obtains after precompressed, hot-forming, demoulding, deburring processing Light thermal insulation board.Plate prepared by the present invention had both overcome organic fire prevention plate without substances that is harmful to the human body such as formaldehyde, VOC Poor, the inflammable disadvantage of fire line, and have the characteristics that light weight, heat preservation, sound insulation value are good, at low cost, with short production cycle, it is applicable in In industry, the non-load bearing wall of civil buildings, roofing, external and internal wall heat preservation and floor between sound insulation, but the invention is light The shock resistance of matter fire resistant heat preserving vermiculite plate is general, and service life is shorter.
Chinese patent CN101941801A discloses a kind of microcrystal glass plate and its production technology, which is characterized in that according to Mass percent, comprising: drift-sand: 52-70, alkali: 10-15, lime stone: 12-18, zinc powder: 3-5, titanium valve: 2-5, fluorite: 3- 5.The present invention provides glass plate and its production technology, micro- to produce building with desert drift-sand without processing for direct material Crystal glass plate provides a new mould to reach the purpose of industrialization sand control with batch production sand for mankind's Desert Control Formula makes desert drift-sand turn bane into boon, turns waste into wealth, and still, the brittleness of the invention microcrystal glass plate is big, and shock resistance is poor, Intensity is lower.
Summary of the invention
