Abstract
The utility model discloses a structure of heat insulation particles of a building. The structure comprises a particle core body formed by an organic foam particle core body, and an inorganic powder coating layer coated on the surface of the outer circumference of the core body. The organic foam particle core body is made from polyphenyl particles or foamed polyurethane particles. The inorganic powder coating layer is formed by mixing silica aerogel and inorganic powder. The structure of the heat insulation particles of the building solves the problem of easiness in burning the conventional organic heat insulation material, the conventional organic heat insulation material is modified, the coefficient of heat conductivity is reduced, and meanwhile, the combustion performance of the original substrate is changed, so that the structure becomes a non-combustible heat insulation material, which conforms to requirements of the heat insulation material of the building.
Description
Technical field
The utility model belongs to material of construction structure field, is specifically related to a structure about the novel building insulation particle.
Background technology
The heat-insulating material is an organism mostly on the market, like polyurethane foam, foam polyphenyl particle, and the foaming phenolic aldehyde; Though these organism are very light as the heat-insulating material, good heat-insulation effect, low price; But these materials all belong to combustible material; Meet fire and promptly fire, each because the fire that the heat-insulating material causes all belongs to painful wildfire, use this lagging material to let people's lives and properties can not get ensureing.Handle yet on these organic lagging material bases, doing fire prevention, except phenolic board more effective, just much more difficult relatively as far as urethane cheap and easy to get, granular polystyrene.And existing on the market inorganic materials is as lagging material; Like rock wool, glass fibre cotton, pearlstone, cenosphere, foam cement, foamed glass, foaming plaster etc.; Its effect of heat insulation is difficult to reach requirement again; Aerosil belongs to the superinsulation material in the inorganic materials, but because it costs an arm and a leg, practice is very unrealistic.
The utility model content
To the problem and shortage that exists in the prior art; The purpose of the utility model is to provide a kind of heat-insulating particulate structure; The heat-insulating particle of this structure has solved very easily incendiary problem of existing organic lagging material; With traditional organic lagging material modification, when reducing its thermal conductivity, change the combustionproperty of original material, make it to become meet the heat-insulating material requirements do not fire lagging material.
The purpose of the utility model realizes through following technical proposals:
A kind of heat-insulating particulate structure comprises the particle core body that is made up of organic expanded beads core body, and the inorganic powder coating layer that coats at this core body external peripheral surface.
Said organic expanded beads core body is made up of granular polystyrene or polyurathamc particle.
Said inorganic powder coating layer is mixed with inorganic powder by aerosil and constitutes.
The difficulty of the utility model is fired the structure of organic foaming heat-insulating material, and critical material is to use the modification main additive layer of the superinsulation nanoporous aerogel of our company oneself production as organic foam material.Its improvement effect of novel building lagging material through the utility model preparation is example with the granular polystyrene: the granular polystyrene basic parameter does, 15 kilograms/cubic metre of density, thermal conductivity 0.037w/m.k, belongs to inflammable material; Material fundamental property through after the gas gel modification is density density 15-150 kilogram/cubic meter, thermal conductivity 0.026-0.035w/m.k, belong to A level fire retardant material.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, organic expanded beads core body; 2, inorganic powder coating layer.
Embodiment
Below in conjunction with embodiment the structure of novel building insulation particle is explained.
As shown in Figure 1, this heat-insulating particulate structure comprises the particle core body that is made up of organic expanded beads core body 1, and the inorganic powder coating layer 2 that coats at this core body external peripheral surface.
Wherein, organic expanded beads core body 1 is made up of granular polystyrene or polyurathamc particle, and inorganic powder coating layer 2 is mixed with inorganic powder by aerosil and constitutes.Inorganic powder is the pearl of wafing, pure aluminium silicate micro mist, gypsum, titanium oxide, zinc oxide, quicklime, calcium sulfate, WHITE CARBON BLACK or fine silica powder material.
The structure of the utility model obtains through following preparation method.
At first, preparation aerosil:
Be that 1: 1 ratio is mixed in container in mass ratio earlier with silicon sol and tetraethoxy; Getting 10 liters of mixtures adds 100 liters of ethanol wherein; Add while stirring with 5 kilograms of water-reducible ammonia solns of 1 kilogram 30%; Regulator solution pH value is 7, adds continued and stirs up to whole solution clear (about 1 hour), and container closure is waited for gel (about 4-8 hour).The gel of getting well wearing out is transferred to and is removed to carry out supercritical drying in the supercritical drying equipment, and its drying conditions is: 290 ℃ of temperature; Pressure 23.5MPa (dry about 10 hours) had both got aerosil.
Secondly, p-poly-phenyl particulate modification
Take by weighing in 50 liters of rare HF solution of 100g granular polystyrene (be organic expanded beads core body 1, push up U.S. lagging material ltd) 1% and soaked 2 hours, leach available from Xi'an; Soak for 50 liters with sodium dodecyl sulfate solution again and leached in 2 hours; With 10 gram aerosils of abovementioned steps preparation, 200g fine silica powder, 200g calcium sulfate mixed grinding 10 minutes; Mixed powder is incorporated in the granular polystyrene of handling through two procedures; Mix, wrap the granular polystyrene surface fully, promptly obtain containing the heat-insulating particle of inorganic powder coating layer 2 up to mixed powder; 60 ℃ of oven dry need 1 hour approximately.
Getting modified particles 100 gram does The performance test results and is: 150 kilograms/cubic metre of density, thermal conductivity 0.035w/m.k, belong to A level fire retardant material.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
