The polyethylene thermal insulation material composite layer structure has the advantages of light weight, attractive appearance, no toxicity and taste, environmental protection, energy conversation, corrosion resistance, ageing resistance, good physical and mechanical properties, high fire proofing grade and long service life.
Description
Technical field
The utility model the utility model relates to a kind of energy-conservation, thermal insulating material structure that consumption reduction is heat insulation that is used for building material field with fields such as HVAC, ventilation airduct, cold and hot, freezing, changes in temperature waterpipe insulation and the traffic tool, especially a kind of polyethylene thermal insulating material lamination layer structure.
Background technique
To above-mentioned field especially building heat preservation field, country has proposed energy-conservation need and has reached 65% standard-required.Industries such as China's building and industry are this requirement of response country, and the requirement at aspects such as energy-conservation, consumption reduction, fire prevention, working life and environmental protection also improves day by day to thermal insulating material, and the upgrading that has driven new material thus is with fast-developing.
Be worth with practicing thrift the working life that tradition insulation monomer thermal-protective material only has short-term; As traditional thermal insulating material, reduced working life special easy-weathering like the inorganic mineral cotton because of being prone to suction; Cause mass defect and environmental pollution easily, be limited in the clean environment place to use; Moulding high-pressure foam material, because of its foam structure itself can not form complete independent hole-closing structure, so moisture permeable coefficient is bigger, and water absorption rate is high, is prone to dewfall, passes through and trembles with fear, and has reduced working life; Closed pore foaming PVC/NPR rubber-plastics material also exists because of being prone to the purpose that deterioration phenomenon can not reach long-term use; The PU foam material is banned use of in the occasion that human settlements are concentrated by people because of the back of burning produces harmful gas gradually.Phenol formaldehyde foam, because water absorption rate is higher, weakness such as intensity difference influence and have limited its use in enormous quantities in special industry.
Because the new material of monomer single structure makes from the market development main body and is used for seeing, still exists the backwardness on various material-structure defectives and the production technology, can't meet the need of market.Compound insulating material exactly can satisfy the various technical requirementss and the market demand of industry, so composite material replaces traditional heat preserving and insulating material to become the inexorable trend of industry development.
Summary of the invention
Because there are many deficiencies in the thermal insulating material of traditional single structure, satisfied not the long-term energy-conservation requirement of industry, the utility model provides the lamination layer structure of a kind of polyethylene (PE) thermal insulating material, has evaded the inferior position that different single structure materials exist.
The technological scheme of the utility model is:
A kind of polyethylene thermal insulating material lamination layer structure comprises extrusion molding crosslinked foaming polyethylene layer 1 and moulding high-pressure foam layer 2.
Extrusion molding crosslinked foaming polyethylene layer 1 is also claimed the XPE layer, and moulding high-pressure foam layer 2 is also claimed the PEF layer,
Further, said composite bed comprises extrusion molding crosslinked foaming polyethylene layer 1, moulding high-pressure foam layer 2 and the extrusion molding crosslinked foaming polyethylene layer 1 of heat seal successively.
Further, said composite bed two outer surfaces or a surperficial heat seal aluminium foil layer or an aluminizer wherein are aluminium lamination 3, also claim the AL layer, and wherein aluminium foil can be done embossing and handles, also can overlay film.
Further, said composite bed two outer surfaces or wherein a surface cover bonding layer 4, also claim G1 layer, can scribble acrylic acid oiliness glue.
Further, said composite bed two outer surfaces are an outer surface heat seal aluminium foil layer or an aluminizer wherein, is aluminium lamination 3, and another outer surface covers bonding layer 4.
Further, described bonding layer covers disengaging paper outward.
Further, said thermal insulating material is a tubulose or tabular, and when the tabular material of MULTILAYER COMPOSITE was thin, also rollable used.
Wherein, aluminium lamination 3 is for protecting aluminium foil embossing heat seal top layer outward, as heat-insulation and heat-preservation material protection layer;
The PE composite foam is by extrusion molding crosslinked foaming polyethylene layer and the layer heat seal of moulding high-pressure foam and the heat-insulation and heat-preservation body that forms.
The beneficial effect of the utility model is:
⑴ protective layer-outer cladded aluminum foil composite material; Fire prevention and moisture barrier property are better, and safety guarantee is higher, can delay the aging speed of foamed heat-insulating material simultaneously; Avoid the defective of substrate surface be full of cracks fully; Can bear the highest temperature and reach 200 ℃ effect, can improve fire-protection rating, prolong material working life.
⑵ one of thermal-protective coating-composite material XPE is novel polyethylene foamed heat-insulating material (the selection thickness 3～15mm through chemistry bridge formation (strengthening crosslinked); Compound back 3～100mm), because the crosslinked hole-closing structure performance of its unique extrusion molding, it is the first to occupy the foamed plastics industry.Its material distinguishing feature is: complete closed pore, and low hydroscopicity, low conduction coefficient, light weight is attractive in appearance, and is corrosion-resistant, anti-aging, and physical and mechanical properties is good, nonpoisonous and tasteless, environmental protection and energy saving.Two moulded from foam polythene PE F of composite material are semi-closure hole polyethylene foam structure, and mechanical strength is relatively poor relatively, but because of it has good low conduction coefficient, softness has good rebound elasticity, therefore are chosen as XPE composite intermediate layer material, form best thermal-protective coating.
⑶ bonding layer-through the form (G1) of a gum of advanced automatic double surface gluer guaranteed that composite material construction back keeps permanent bond intensity and permanent stripping property not, and self-adhesive does not contain harmful matters such as formaldehyde, toluene; Nonpoisonous and tasteless, satisfied environmental requirement, the centrifugal paper of silicon will be arranged as being coated with compound protective layer; Easy to use; Saving of work and time has avoided the artificial gluing of traditional material to use and situation about wasting time and energy, and has realized that prefabrication is integrated.
⑷ it is good that have weatherability in addition, and thermal insulation property is outstanding, and little, the convenient construction of density has advantages such as good physical mechanical property, vibration damping, resistance to compression.
Polyethylene thermal insulating material with the utility model lamination layer structure can be applicable to build underground structure protective layer, building roof membrane, with insulation in main structure body of wall and ground, the insulation of structural metal structure roofing wallboard interior trim, the decorating outer wall of building plate, joint filler for building, concrete structure maintenance protection material; Central air-conditioner ventilation duct and cold and hot pipeline corrosion-resistant thermal insulation, chiller plant insulation, combustion gas gas pipe line; Bonding insulation etc. in the car body hull.
