Background technology
At present China's heat insulating material for building, particularly wall heat insulation material be mainly taking organic insulation material as main, wherein polystyrene (EPS, XPS) occupation rate of market approximately 90%, and polyurethane (PU) is 10%.Because material self character and fire prevention control measures are not implemented completely, fire incident happens occasionally, and these fire generation direct economic losses are billions of, and indirect loss is tens billion of, and causes certain society's fear and environment pollution.
In order to ensure safety, the portion that firmly builds combines and has issued file No. 46 with the Ministry of Public Security for 2009, and the use of heat insulating material fire-protection rating is specified.The Fire-Fighting Bureau under the Ministry of Public Security has issued again No. 65 file in 2011, further carried out code requirement, and having made civilian construction heat insulating material employing burning grade is the material of A level.
Tradition rock, mineral wool can reach fire prevention A level, but due to factors such as output and self water absorption rate height, can not meet the demand in market.Vacuum heat-insulating plate, because of the advantage of its excellent heat insulation effect, fire prevention, environmental protection, saving usage space, is specially adapted to the reducing energy consumption of existing building and is favored gradually.But not only needing to meet weather-proof and good mechanics and heat insulation effect for building energy conservation, and need to meet the stress requirement of negative and positive angular position, there is cracking, infiltration phenomenon in conventional vacuum heat-insulating plate is subject to stress impact at position, construction wall corner.
Therefore need to invent a kind of special vacuum heat-insulating plate in negative and positive angular position that is applicable to build.
Summary of the invention
The present invention aims to provide a kind of construction wall negative and positive angle Special vacuum heat insulating thermal preserving board and preparation method thereof, and the problem of cracking, infiltration phenomenon appears in the impact that is subject to stress to solve vacuum heat-insulating plate that prior art exists at position, construction wall corner.
Technical scheme of the present invention is: a kind of construction wall negative and positive angle Special vacuum heat insulating thermal preserving board, comprise two plate bodys and be connected to the turning groove of the 7-20mm together between it, two plate bodys are made up of two blocks of cores of inserting in the high-barrier composite film of bag shape, in turning groove, there is no core, only have two-layer high-barrier composite film to be combined with each other; Periphery at the high-barrier composite film of bag shape is provided with pressing limit, and described pressing limit is arranged on a relative side of the connection turning groove place side of each plate body; Two plate bodys of turning groove guarantee can be rolled in 90 °; Two plate body inside vacuumize;
Described high-barrier composite film is composited by the glass-fiber-fabric in outside and the composite membrane of inner side;
Described composite membrane comprises that any one film of PVDC, PA, PE, PP, PVOH, EVOH, PET, nylon, PS, aluminium foil material or several Film laminateds wherein form;
The preparation method of described construction wall negative and positive angle Special vacuum heat insulating thermal preserving board, comprises the following steps:
(1), prefabricated core is cut into (100-300) mm × (100-300) sheet material of mm;
(2), the sheet material cutting is placed in high temperature drying case to removal moisture drying;
(3), the both sides of every block of core plate are held successfully and placed the slotted eye of getter, and put into getter, be used for adsorbing in evacuated panel after exhaust gas remaining in plate and the gas from external penetration to intralamellar part;
(4), the high-isolation film that covers glass-fiber-fabric is outward made to the high-isolation film bag that can fill two discontinuous cores;
(5), the core of handling well is put into the high-isolation film bag making, and put into vacuum chamber exhaust;
(6), mix up in advance cylinder pressure, heating-up temperature and the sealing time of vacuum sealer in the time of sealing; In the time that the indoor vacuum of vacuum reaches 0.02-10Pa, seal.
Advantage of the present invention is: not only possess the heat insulation effect of vacuum heat-insulating plate excellence and high water resistance, paracentesis resistance, damage resistant, anti-aging, and can be converted into as an overall sheet material angle that building negative and positive angle needs, greatly avoid the impact of negative and positive angular position stress on heat-insulation system.
