Description
Technical field
The invention belongs to the building thermal insulation material field, is a kind of building zone segregation inorganic fire warming plate and preparation method thereof.
Background technology
In recent years, along with the continuous prosperity and development of economy, economic construction is maked rapid progress, Highrise buildings is also rised sheer from level ground like rain the back spring bamboo in big or middle city and even small city.Because Highrise buildings is high, the number of plies is many, and functions of use is complicated, and personnel are intensive, in case presence of fire, fire spread is rapid, evacuating personnel and fire attack difficulty, certainly will lead to loss greatly, injures and deaths are big.Because Highrise buildings itself has the internal gas flow recycle system, building heat preservation is heat insulation essential, and at present, the lagging material overwhelming majority that China's Highrise buildings adopts all is the organic foaming insulation board of polymer, like EPS (molded polystyrene cystose), XPS etc.Their defective is to have a little Mars to burn at once, and rate of propagation is exceedingly fast.Since so dangerous, why also used so on a large scale such as organic insulation materials such as EPS, XPS? This is because of these lower cost for material, high insulating effect, and certain mechanical strength and snappiness are arranged, and water-intake rate is low, and easy construction is prone to cutting.According to the data that ANS technical institute (NIST) announces, EPS warming plate thermal conductivity is 0.041, and the XPS warming plate then is 0.03, and heat-insulating property is very good.But their shortcoming also clearly: inflammable and easy to be aging.In a single day these lagging materials burn, it is very fast to overdo, and produces a large amount of poisonous and harmful flue gases simultaneously, is a great potential safety hazard.According to statistics, only in Beijing, what the Highrise buildings lagging material more than 90% adopted all is this family macromolecule foaming insulation board.In recent years repeatedly fire causes by these inflammable lagging materials.Therefore, need study novel Highrise buildings zone segregation fire protection flame retarding lagging material,, avoid and reduce fire injures and deaths and property damage for the escape of fire of high-rise building offers an opportunity.
Summary of the invention
The purpose of this invention is to provide a kind of fire resistance property that can improve the Highrise buildings heat-insulation system, stop fire spread, play fire prevention partition, fire-retardant, and nontoxic, harmless building zone segregation inorganic fire warming plate.
Another object of the present invention provides a kind of preparation method who prepares building zone segregation inorganic fire warming plate.
Realize that the technical scheme that the object of the invention is taked is: this warming plate is that the preparation of raw material by following weight part forms: particle diameter is that 50～70 parts in 1～4mm expanded perlite granule material, particle diameter are 4～8 parts of the converter slag particulate material of 1 ~ 2mm, 7～12 parts of rock wools, silicon sol or 15～25 parts of powdery quick dissolved sodium silicates, 2～6 parts of the water-resisting agents that Fibre diameter is 0.1 ~ 0.5mm; What wherein, water-resisting agent adopted is inorganic aluminate water-proof agent or concrete waterproofer or waterproofing agent of organosilicon.
Warming plate of the present invention prepares by following step:
1) gets 15～25 parts of 7～12 parts of 50～70 parts in expanded perlite granule material that particle diameter is 1～4mm, 4～8 parts of converter slag particulate material that particle diameter is 1 ~ 2mm, rock wools that Fibre diameter is 0.1 ~ 0.5mm and silicon sol or powdery quick dissolved sodium silicates and 2～6 parts of water-resisting agents by weight ratio; Behind the uniform mixing; It is subsequent use to process compound; Wherein, the powdery quick dissolved sodium silicate must the weight ratio by 1:1 add the clear water dissolving before mixing;
2) get compound and add water, under normal temperature condition, mix, process the mixing wet feed by the weight ratio of Hun He Liao ︰ water=1 ︰ 1.5～3;
3) will mix wet feed and insert in the slab mould of pressing machine, be the wet base of warming plate through pressing machine compression moulding;
4) dry: the wet base of warming plate is inserted in the stoving oven dry, 100～150 ℃ of bake out temperatures, drying time 8～12 hours, take out the oven dry back, is the fireproof heat insulating board finished product.
The present invention selects for use above-mentioned raw materials to make up, and through the synergy of each raw material effect, makes the warming plate of making have higher intensity, toughness and good fire prevention, exhausted combustion, heat insulation, sound insulation, protection against the tide, performance such as anticorrosion.In the raw material of being prepared, the inside of pearlstone is polynuclear plane, have nontoxic, tasteless, do not fire, in light weight, effect such as thermal insulation and sound absorption qualities are good; Rock wool is to be main raw material with selected natural rock, blast-furnace slag; Add the auxiliary material of some amount; The regenerated fiber of processing through high-temperature fusion winding-up; Have do not fire, nontoxic, characteristics such as thermal conductivity is low, sound absorption qualities good, insulation, chemical stability is good, life cycle is long, be the desirable heat preserving and insulating material of generally acknowledging both at home and abroad; And the granule interior of converter slag has a lot of micropores, and has high compression strength; These three kinds of raw materials are with after silicon sol or quick dissolved sodium silicate mix; Make the warming plate of making not only can play fire prevention, fire-retardant and insulation, heat insulation effect; And have stronger cohesion and a cohesive strength; And can increase the ultimate compression strength of warming plate, under the effect of adding water-resisting agent, strengthened the hydrophobic nature of warming plate and the repellency of moisture simultaneously.
According to the building zone segregation inorganic fire warming plate that the batching of such scheme is processed, its beneficial effect is:
1, the density of this warming plate is at 350Kg/M
3Below, thermal conductivity 0.060～0.085 W/mK has that unit weight is light, a good heat insulating, distinguishing features such as ultimate compression strength is high, avidity is strong, good toughness, shrinking percentage are little, easy construction.
2, the warming plate of processing can effectively improve the fire resistance property of building heat insulation system, and its fire protection flame retarding property is good, when occurring catching fire, can stop fire spreading effectively, and has good heat preservation and insulation.
3, this warming plate all adopts nontoxic, harmless natural mineral raw, and have the good adsorption detoxifying properties and tasteless, nontoxic, do not fire, advantage such as unit weight is light, can receive excellent environment protecting with the warming plate of its making.
