Description
Technical field
The utility model belongs to engineering heat supply plastic pipe field, in particular to a kind of expanded polystyrene (EPS) direct-burried heat preservation
Plastic composition pipeline, it is specifically a kind of in central heating network field, five layers of one kind for thermal medium conveying heat supply
Integral structure pipeline.
Background technique
The existing outdoor prefabricated direct-buried thermal insulating plastic composite tube material of central heating (hereinafter referred to as insulating plastic pipe pipe), with resistance to hot polymerization
Ethylene (PE-RT II) resin is work inner tube, using polyurethane material as sandwich layer insulating layer, with hdpe pipe for outer shield
Pipe.Its center core layer heat-insulating layer foaming pours foaming using polyurethane, due to cost and material source problem, uses fluorine-containing hair always
Infusion is produced, but such foaming has environmentally friendly hidden danger, and at high cost.More environmentally friendly cyclopentane systems at present, there is also
Inflammable and explosive disadvantage, there are security risks for production and processing, and cost is also relatively high.
In addition, traditional " two step method " production method is: must be first by work in the production of insulating plastic pipe pipe and process
Make inner tube to squeeze out, after fixed length cutting, then carry out polyurethane and pour foaming, production efficiency is low, higher cost, is unfavorable for pushing away on a large scale
Wide application；And for " one-step method " polyurethane foam technique, the disadvantage is that can not be applied in heavy caliber specification, and expansion density without
Method reaches 60kg/m3Requirement.
This problem is not can solve in well known patent or in the prior art at present.
Summary of the invention
The purpose of the present invention is to overcome the polyurethane insulation coating of insulating plastic pipe pipe in the prior art in processing and manufacturing process
In, there is environmental protection and security risk in foaming raw material, and defects, the utility model such as production efficiency is low provide a kind of foaming polyphenyl second
Polystyrene resin extrusion molding is processed, is reached by using blown with carbon dioxide by alkene direct-burried thermal insulating plastic composite tube road
To the effect of One-step production, to complete the production of expanded polystyrene (EPS) insulating layer.
The present utility model purpose is achieved through the following technical solutions:
A kind of expanded polystyrene (EPS) direct-burried thermal insulating plastic composite tube road, the compound pipeline complex pipeline are a kind of five layers of composite constructions,
Internal layer is made of a kind of heat-proof polythene (PERT II) resin, and insulating layer is a kind of extrusion type expanded polystyrene (EPS) material, outer layer
For a kind of high intensity PE polyvinyl resin composition, the binder course between internal layer and insulating layer is coated with one layer of bonding agent；It is protecting
Binder course between warm layer and outer layer is coated with one layer of bonding agent.Internal layer and insulating layer, insulating layer Yu Wai Eng are connected by bonding agent
It is connected in one.
The heat-resisting II type polyvinyl resin of PERT of the endothecium structure is a kind of PE100 grade high-performance based on hervene copolymer
Polyethylene mixed ingredients, have the characteristics that corrosion-resistant, heat-resisting, pressure-resistant, and highest is heat-resisting up to 95 DEG C, and pressure is used up to 1.0MPa
Service life was up to 50 years or more.
The insulating layer extrusion type expanded polystyrene (EPS) material is a kind of using the poly- of blown with carbon dioxide extrusion moulding
Styrofoam (XPS) has uniform closed honeycomb structure, low thermal conductivity, high pressure resistance and good plasticity
And the feature of environmental protection.
The cladding material is made of high-intensitive PE100 polyvinyl resin, has excellent ductility and mechanical resistant
Energy.
Bonding agent between internal layer and insulating layer and outer layer and insulating layer is EVA resin modified ethyl acetate, diformazan
Ether bonding agent has good adhesive property.
The utility model is due to using five layers of composite construction, in heating power conveying, by II type polyethylene of internal layer PERT
Pipe bears the pressure and heating power that conveying heating power generates, and carries out adiabatic heat-insulation by intermediate expanded polystyrene (EPS) insulating layer, prevents
Outside heat losses to inner tube, the outer cold current intrusion internal layer of pipe is also effectively prevented, to play heat preservation, antifreeze function.Outer layer is adopted
With high-density polyethylene material, while guaranteeing composite pipe critical external compressive resistance, anti-scratch ability, can also play certain heat preservation,
Antifreeze effect, due between II type polyethylene inner tube of polyethylene foamed insulating layer and internal layer PE-RT；It is glued between insulating layer and outer layer
Attached property is poor, for the integraty for guaranteeing tube performance, combines interlayer to be respectively coated with one layer of bonding agent at it, makes between each layer effectively
It is adhesive into one.
The beneficial effects of the utility model are: since composite pipe uses overall plastic composite construction, corrosion resistance and good, tubing
It is light-weight, it is connected using heat-melting butt-joint or electric melting sleeve, connection safety in utilization is improved largely, using blown with carbon dioxide
Polystyrene foam plastics (XPS) is used as insulating layer, has effectively prevented the environmental pollution and security risk in production process；Benefit
With the preferable feature of polystyrene foam plastics (XPS) mobility, continuous extrusion is carried out by co-extruding mould, so that
Multiple tube can continuous production, improve production efficiency.It can widely be applied in central heating network field, instead of traditional steel
Pipe insulating tube, comprehensive cost low, long service life, later maintenance are easy to spread universal at low plurality of advantages.
