Abstract
The utility model discloses a structurally-improved vacuum heat insulating plate. The vacuum heat insulating plate comprises a core plate, an airtight inner film and an air tight outer film, wherein the core plate is sealed in the inner film in a vacuum mode; and the integrated part formed by the core plate and the inner film is sealed inside the outer film in a vacuum mode. The vacuum heat insulating plate is manufactured into a vacuum heat insulating plate by performing vacuumization for twice, so that the vacuum degree of the vacuum heat insulating plate is effectively improved; and four sides of a sheet are reduced into two sides by virtue of a composite middle seaming bag, so that the vacuum heat insulating plate is convenient to mount, and the cold-heat bridge phenomenon is reduced; and by utilizing the composite middle seaming bag with the secondary glass fiber plastics and the outer layer of glass fibers, the adhesion force of the heat insulating plate and the wall body can be improved when the vacuum heat insulating plate is mounted.
Description
Technical field
The utility model relates to a kind of vacuum heat-insulating plate, particularly a kind of vacuum heat-insulating plate of architecture advances.
Background technology
In the present technology, vacuum heat-insulation plate mostly adopts the high-barrier aluminum-plastic composite membrane to make the soft shell vacuum bag.Building heat preservation is divided into aquiclude, reflecting layer, gas barrier layer, hot sealing layer with the high-barrier aluminum-plastic composite membrane, and is bonding with polyurethane adhesive between each layer, and the gas barrier property quality of vacuum chamber directly affects life-span and the use of vacuum heat-insulation plate,
In order to improve the gas barrier property of vacuum chamber, the number of plies of a lot of producers raising aluminum-plastic composite membrane simply realizes, but the more thickness of the number of plies of aluminum-plastic composite membrane are thicker, cause aluminum-plastic composite membrane hardening, easy fracture, heat-sealing defect rate to increase, the more composite layers of the number of plies increase in addition, the side gas infiltration capacity of glue-line strengthens, and has affected the application life of vacuum heat-insulation plate.
The PET film is adopted on the top layer of vacuum diaphragm mostly, and smooth surface inadequate with the body of wall bonding force, comes off after can causing wall.
Present building heat preservation is that the central layer raw material is carried out physical mixed, oven dry, wraps up with nonwoven after compressing again with the vacuum heat-preserving plate producing process, makes required specification.Then the choke vacuum chamber of packing into is made by vacuum equipment application of vacuum sealing.Because use nonwoven to wrap up, moulding final vacuum heat-insulating plate has four limits, easily produces the cold-heat bridge phenomenon, and only through once vacuumizing, easily produces the not high situation of vacuum.
The utility model content
In order to remedy above deficiency, the utility model provides a kind of vacuum heat-insulating plate of architecture advances, and the vacuum heat-insulating plate vacuum of this architecture advances is high, and good heat-insulation effect is large with the metope bonding force, easy for installation, firm.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of vacuum heat-insulating plate of architecture advances, comprise central layer, air-locked inner membrance and air-locked adventitia, the inside of inner membrance is located in described central layer vacuum seal, and adventitia inside is located in central layer and interior film formed overall vacuum sealing.
As further improvement of the utility model, described inner membrance is aluminum-plastic composite membrane, it is followed successively by polyethylene (PE) layer, nylon layer and PETG (PET) layer from inside to outside, adventitia is the fiberglass plastic composite membrane, and it is followed successively by polyethylene (PE) layer, aluminium foil layer, nylon layer and glass layer from inside to outside.
As further improvement of the utility model, described adventitia is the compound middle bagging of fiberglass plastic.
As further improvement of the utility model, the vacuum orifice place of the compound middle bagging of described fiberglass plastic is provided with inside and outside two sealings.
Production of the present utility model is carried out in the steps below:
Step 1: core material of vacuum heat insulation plate installed to carry out in the aluminum-plastic composite membrane vacuumizing the first time, and seal;
Step 2: the vacuum heat-insulating plate of being pumped into for the first time type is placed in the compound middle bagging of fiberglass plastic carries out vacuumizing second time, exhaust vacuum vacuum orifice is carried out sealing processing second time.
The beneficial effects of the utility model are: the utility model vacuumizes through twice and makes vacuum heat-insulating plate, can effectively improve the vacuum of vacuum heat-insulating plate, the use of compound middle bagging is reduced to two limits with four limits of sheet material, the convenient installation, reduce the cold-heat bridge phenomenon, utilize simultaneously for the second time compound middle bagging of fiberglass plastic, outer field glass fiber, the bonding force of thermal insulation slab and body of wall in the time of can improving the vacuum heat-insulating plate installation.
