A kind of light thermal-insulation partition board

Technical field

The utility model relates to a kind of partition board, relates in particular to a kind of heat insulating ability, sound insulation value is good, light weight, the light thermal-insulation partition board of environmental protection.

Background technology

Economic develop rapidly since China's WTO accession, science and technology is improving new results, new product is being constantly updated, constructional materials is again one of flourishing progressive distinctive marks of country, at present China's wall board material output is compared tangible too wide in the gaply with developed country novel wall material, marks time in the old road that particularly China some areas also rest on ancient Qin brick and Han tile and haydite hollow brick.Party and state leaders is to conceding the land to forestry, and the environmental protection state basic policy of protection ecological resources is paid attention to especially.Premier Wen Jiabao points out: " greatly develop novel environmental-friendly construction material, replace sandstone power consumption height and take up an area serious solid clay brick with ruining, take leave of Qin brick and Han tile, save every inch of land, benefit descendants, give good living environment of the people ".

In north cold area, heat-insulating property and energy-conservation the having relatively high expectations of building, complex heat-preservation sandwich wall board is to develop on the basis of sheet material, there is lightweight, high-strength, heat insulation, sound insulation, fire prevention, antidetonation, the easy advantage such as assembling, this wallboard is paid much attention to, not only, for new construction, in the maintenance works of building, be also applied.Indoor thermal environment of building is required comfortable in, people also have comfortable demand to architecture indoor acoustic environment, not only pay attention to insulation, the sound insulation property of external wall protection body of building, the sound insulation property of internal partition wall also obtains people's attention day by day.

Building energy conservation theory has been subject to common concern, though existing heat-preservation partition board light weight, intensity a little less than, light thermal-insulation partition board is as a kind of energy-saving material and multifunction and become the focus of research and development.

In the heat insulating material of China's commercial Application, have inorganic heat insulation material (belonging to A level heat insulating material) and organic insulation material (belonging to B level heat insulating material) two large classes, inorganic heat insulation material has rock wool class (being restricted), calcium silicates, perlite, foam glass, expanded vermiculite etc. conventionally; Organic insulation material has polystyrene, polyethylene, polyvinyl chloride, polyurethane foam etc.

Comparatively speaking, organic heat insulating material coefficient of thermal conductivity is all less, and between 0.035W/ (mk) ~ 0.045W/ (mk), under cryogenic conditions, (normal temperature) heat insulation effect is better; Mineral-type heat insulating material coefficient of thermal conductivity is larger, and between 0.065W/ (mk) ~ 0.095W/ (mk), heat insulation effect is poor, but can under hot conditions, use.Therefore, substantially, Building class (genus cryogenic conditions) insulation adopts organic material in the application of China's heat insulating material at present; Industrial thermal pipe class (hot conditions) adopts inorganic heat insulation material.

There are two fatal shortcomings that cannot overcome in organic heat insulating material (polyurethane foam, polystyrene, polyvinyl chloride), and the one, inflammable, the 2nd, non-refractory (180 DEG C of carbonizations, lose heat-insulating property).

In December, 2010, the Ministry of Public Security expressly provided the application of restriction B level (organic) heat preservation plate material in external wall, and in March, 2011 Ministry of Public Security expressly provided and forbidden the application of B level (organic) heat preservation plate material in external wall, and set up fire department and participated in one of construction work examination, organic flammable heat insulating material is prohibited from using architectural, provides effective guarantee from law and operating characteristics.This to organic heat insulating material in architectural application, extinction only not.

Therefore develop pure organic flammable (B level) heat insulating materials such as can reaching (coefficient of thermal conductivity is below the 0.050W/ (mk)) of insulation effect, alternative polyurathamc, polystyrene, and possessing A level, not fire the thermal insulation material of advantage performance (field such as available external wall, heat distribution pipeline) very urgent.Only have mineral-type heat insulating material to meet not burn the fire-fighting requirement of (A level), but the heat-insulating property of existing inorganic heat insulation material is all poor, cannot meets 65% building energy conservation requirement (if reach energy-conservation requirement, will corresponding increase insulation layer thickness).There is another fatal shortcoming in existing inorganic heat insulation material, unit weight is excessive.Therefore, existing mineral-type heat insulating material uses on building, and is faced with formidable challenges equally.

Therefore, can develop a kind of heat insulating material and both can meet A level and do not fire fire-fighting requirement, can meet again heat insulating ability requirement (heat conduction is little, good heat preservation performance) and the construction requirement of low unit weight is necessary simultaneously.
