Description
Technical field
The present invention relates to a kind of aluminium alloy type timber-used heat-barrier material and preparation method thereof, belong to heat-barrier material field.
Background technology
Two kinds of the existing penetrating bar type of bridge insulation thermal resistance aluminium section and glue injection type.Glue injection type bridge-cut-off insulated aluminium section bar is than penetrating bar type section bar
Excellent in appearance, it is the current trend for saving aluminium section bar market development with better seal, sound deadener/insulator and structural strength
Place.
Glue injection type bridge cut-off technology refers to that injection aluminium alloy extrusions is heat-insulated after liquid two component polyurethane heat-barrier material is mixed
In groove and solidify, cut off the interim connecting bridge in aluminium alloy extrusions heat dam and be allowed to disconnect metal connection, will by heat-barrier material
The complex method that two parts that aluminium alloy extrusions disconnects are combined together.
Patent application CN 103628772A disclose a kind of foam-filled section bar and foam-filled technique, the expanded material
