Abstract
Polyurethane coating polyethylene is wound around insulating tube, it is wound around outer jacket by working steel tube, polyurethane insulation coating and polyethylene to form, polyurethane insulation coating and polyethylene are wound around between outer jacket and arrange epoxy resin bonding glue-line, polyurethane insulation coating spray coating is on working steel tube surface, and epoxy resin bonds glue-line built-in fire retardant nonwoven fabric layer.This utility model arranges epoxy resin bonding glue-line by being wound around between outer jacket at polyurethane insulation coating and polyethylene, epoxy resin bonding glue-line built-in fire retardant nonwoven fabric layer, it is effectively increased insulating tube overall flame effect, has that simple in construction, anti-flammability be excellent and the advantage of length in service life.
Description
Technical field
This utility model relates to heating and cooling engineering pipe technology field, is specifically related to a kind of polyurethane coating polyethylene
It is wound around insulating tube.
Background technology
Along with central cooling, the universal and development trend of energy-saving and emission-reduction of heat supply, the most newly-built, reconstruction project makes
Use direct-burried heat preservation pipe prefabricated.Existing polyurethane coating polyethylene is wound around insulating tube and there is following defect: polyurethane insulation coating
Inflammable, cause insulating tube overall flame poor-performing, the contact area between polyurethane insulation coating and interior tube-surface is less in addition,
The problem that polyurethane insulation coating is separated by interior tube-surface and comes off easily occurs during use.
Utility model content
This utility model provides a kind of polyurethane coating polyethylene and is wound around insulating tube, to solve the poly-of prior art existence
Urethane heat-insulation layer is inflammable, the poor problem separating with polyurethane insulation coating and coming off of fire resistance.
This utility model is wound around outer jacket by working steel tube, polyurethane insulation coating and polyethylene and forms, and solves its technology and asks
Inscribe employed technical scheme comprise that polyurethane insulation coating and polyethylene is wound around between outer jacket and arranges epoxy resin bonding glue-line, poly-
Urethane heat-insulation layer spray coating is on working steel tube surface, and epoxy resin bonds glue-line built-in fire retardant nonwoven fabric layer.
This utility model arranges epoxy resin adhesive glue by being wound around between outer jacket at polyurethane insulation coating and polyethylene
Layer, epoxy resin bonding glue-line built-in fire retardant nonwoven fabric layer, it is effectively increased insulating tube overall flame effect, there is structure letter
Single, anti-flammability is excellent and the advantage of length in service life.
Accompanying drawing illustrates:
With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of this utility model insulating tube.
In figure, 1 working steel tube, 2 polyurethane insulation coatings, 3 polyethylene are wound around outer jacket, 4 fire retardant nonwoven fabric layers, 5 epoxy resin
Bonding glue-line.
Detailed description of the invention:
As it can be seen, a kind of polyurethane coating polyethylene is wound around insulating tube, by working steel tube 1, polyurethane insulation coating 2 and poly-
Ethylene is wound around outer jacket 3 and forms, and polyurethane insulation coating 2 and polyethylene are wound around between outer jacket 3 and arrange epoxy resin bonding glue-line
5, polyurethane insulation coating 2 spray coating is on working steel tube 1 surface, and epoxy resin bonds glue-line 5 built-in fire retardant nonwoven fabric layer 4.
This utility model arranges epoxy resin adhesive glue by being wound around between outer jacket at polyurethane insulation coating and polyethylene
Layer, epoxy resin bonding glue-line built-in fire retardant nonwoven fabric layer, it is effectively increased insulating tube overall flame effect, there is structure letter
Single, anti-flammability is excellent and the advantage of length in service life.
