Technical field
The present invention relates to special-purpose vacuum thermal insulation plate in a kind of construction wall negative and positive angle and preparation method thereof, be mainly used in.
Background technology
At present China's heat insulating material for building, particularly wall heat insulation material is main with organic insulation material mainly, and wherein polystyrene (EPS, XPS) occupation rate of market is about 90%, and polyurethane (PU) is 10%.Because the material self character is not implemented completely with the fire prevention control measures, fire incident happens occasionally, and these fire generation direct economic losses are billions of, and indirect loss is tens billion of, and causes certain social fear and environment pollution.
In order to guarantee safety, firmly build the portion and the Ministry of Public Security and united in 2009 and issued file No. 46, the use of heat insulating material fire-protection rating is stipulated.The Fire-Fighting Bureau under the Ministry of Public Security has issued No. 65 file again 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 because factors such as output and self water absorption rate height have satisfied not the demand in market.Vacuum heat-insulating plate is 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 favored gradually.Not only need satisfy weather-proof and good mechanics and heat insulation effect but be used for building energy conservation, and need satisfy the stress requirement of negative and positive angular position, conventional vacuum heat-insulating plate is subject to stress influence and cracking, infiltration phenomenon occur at position, construction wall corner.
Therefore need a kind of special-purpose vacuum heat-insulating plate in building negative and positive angular position that is applicable to of invention.
Summary of the invention
The present invention aims to provide special-purpose vacuum thermal insulation plate in a kind of construction wall negative and positive angle and preparation method thereof, and the vacuum heat-insulating plate that exists with the solution prior art is subject to the problem that cracking, infiltration phenomenon appear in stress influence at position, construction wall corner.
Technical scheme of the present invention is: the special-purpose vacuum thermal insulation plate in a kind of construction wall negative and positive angle; It is characterized in that; Comprise two plate bodys and be connected the turning groove of the 7-20mm together between it; Two plate bodys are made up of two blocks of cores in the high-barrier composite film of inserting bag shape, have only two-layer high-barrier composite film to be combined with each other at this turning groove place; Two plate body inside vacuumize.
Described high-barrier composite film is composited with inboard composite membrane by the glass cloth in the outside.
Described composite membrane comprises that any one film of PVDC, PA, PE, PP, PVOH, EVOH, PET, nylon, PS, aluminium foil, aluminum plated PET material or several kinds of films wherein are composited.
The preparation method of the special-purpose vacuum thermal insulation plate in a kind of construction wall negative and positive angle is characterized in that, comprises step:
(1), prefabricated core is cut into the sheet material of mm of (100-300) mm * (100-300);
(2), the sheet material that cuts is placed in the high temperature drying case removal moisture drying;
(3), hold the both sides of every block of core plate successfully place getter slotted eye, and put into getter, be used for
Interior remaining gas of plate and the gas from the external penetration to the intralamellar part after the interior exhaust of absorption evacuated panel;
The high-isolation film that (4), will cover glass cloth is outward processed the high-isolation film bag that can adorn two discontinuous cores;
(5), the core of handling well is put into the high-isolation film bag that makes, and put into the vacuum chamber exhaust;
(6), mix up in advance vacuum sealer when sealing cylinder pressure, heating-up temperature and seal the time;
When the indoor vacuum of vacuum reaches 0.02-10Pa, seal.
Advantage of the present invention is: not only possess excellent heat insulation effect of vacuum heat-insulating plate and high resistant water-based, paracentesis resistance, damage resistant, anti-aging; And can be converted into the angle that building negative and positive angle needs as a whole sheet material, avoided of the influence of negative and positive angular position stress greatly to heat-insulation system.
