Description

A kind of polyurethane combined material, its building structure prepared cold bridge high-strength thermal insulation that breaks Polyurethane material and preparation method thereof
Technical field
The invention belongs to polyurethanes technology field more particularly to a kind of polyurethane combined material, its building structure prepared use Disconnected cold bridge high-strength thermal insulation polyurethane material and preparation method thereof.
Background technology
Freezer is the warehouse for being created suitable humidity and low temperature environment using cooling installation, belongs to the warehouse class of industrial building Not.Since there are internal-external temperature differences, if dealt with improperly, " cold bridge " phenomenon is will appear during the use of freezer, so as to cause Energy consumption is significantly increased, can also generate frosting, icing, dew condensation phenomenon at some positions, not only reduce the heat-proof quality of freezer, even Fabric structure can be destroyed.
Cold-storage door position is due to being the cold and hot place for exchanging most serious inside and outside freezer, while in the ground of passageway through normally open Cold bridge existing for outer floor junction should be disconnected inside and outside floor using heat-barrier material herein, and insulation cover plate is spread above insulating layer. Traditional cover board generally uses lining, wooden lining to be rolled by long-term fork truck, it is easy to be destroyed, the condensation on doorway Water can also be seeped into following thermal insulation layer along gap, and thermal insulation layer heat-insulating property is caused to fail.In order to avoid destroying, some engineerings are used instead Steel deck-plate is embossed, although more durable, steel plate itself is also apparent cold bridge.Long-term practice finds that nylon material takes into account height Intensity and both heat-insulated characteristics can be used as cold-storage door passageway cover plate materials.But polyurethane material compares nylon material, Heat-insulating property is more superior, and sealing the gas in abscess up for safekeeping has the extremely low coefficient of heat conduction, can be increased using glass composite polyurethane Add the intensity of polyurethane material, therefore can keep tough without crisp, low thermal conductivity, high compressive strength at low temperature, it can be maximum The reduction heat exchange of limit.In addition, polyurethane material preparation process is simple, technology is more succinct, can be applied not only to partition library door Cold bridge existing for floor junction inside and outside the ground of passageway applies also for load-bearing beam column and connecting wall or ground in partition freezer Cold bridge, prevent because cold bridge cause frosting, icing, moisture condensation etc. destroy thermal insulation layer heat-insulating property, to reduce the power consumption of freezer.
Although existing polyurethane material can reach lower thermal coefficient, nylon material is still not achieved in its compression strength Expect the level of 50MPa or more.
To sum up, a kind of building structure poly- ammonia of cold bridge high intensity that breaks is prepared in present invention problem in view of the prior art Ester material.
