Description
Technical field
The utility model relates to the metallic conduit composite protective material.
Background technique
In the existing market; the insulation antiseptic of metallic conduit; the general site operation that adopts; mainly comprise three-layer protection from the inside to the outside: 1; corrosion resistant coating; 2; thermal-protective coating; 3; protective layer; the method of this site operation operation has very big influence to construction speed, and construction the time takes up room big; the job site environment seems dirty; disorderly; difference; and on-the-spot the coating for accelerating construction progress, just with banding together behind thermal-protective material or the protective material parcel, such constructing operation makes the gap between layer and the layer very big; sticking nature can be bad, do not reach best protection effect.Thermal-protective coating generally adopts the polyurethane foam material, and its environmental-protecting performance is relatively poor relatively.
Summary of the invention
At the defective in the above-mentioned field, the utility model provides a kind of composite protective material, can be used for the protection of metal pipe, its insulation, keep away shake, buffering, anticorrosion, very good every wet performance, be metal pipe favorable protection material.
The utility model also provides the conveyance conduit that comprises this composite protective material simultaneously.
Composite protective material is characterized in that: being fitted by anticorrosion thin layer, thermal-protective coating and protective layer trilaminate material successively forms.
Described anticorrosion thin layer is ethylene-vinyl acetate copolymer/Nano composite material of montmorillonite.
Described thermal-protective coating is that density is 25-33Kg/m
3The XPE material.
Described protective layer is that density is 150-250Kg/m
3The XPE material.
Described composite protective material is that tube wall one side is the tubing of opening diametrically, and described tubing is distributed as anticorrosion thin layer, thermal-protective coating and protective layer from inside to outside successively.
Described protective layer is longer than thermal-protective coating and anticorrosion thin layer in the tube wall circumferential direction.
Comprise the conveyance conduit of this composite protective material, it is characterized in that: be coated with above-mentioned composite protective material on the tube wall of metallic conduit, described composite protective material is distributed as anticorrosion thin layer, thermal-protective coating and protective layer from inside to outside successively.
One end of described metallic conduit stretches out in the outside of composite protective material, and the other end shrinks in the inside of protection material.
Described coating is the tube wall epirelief desk-top overlap joint hot weld seal form of composite protective material at the metal conveyance conduit.
The utility model composite protective material includes anticorrosion thin layer, thermal-protective coating and protective layer; this trilaminate material fits together; has good sticking nature energy between three layers; its insulation, every wet, antiseptic property is very good; on-the-spot only need it is coated on the tube wall of metallic conduit just passable, workability is very good.
Anticorrosion thin layer is EVA/OMMT (ethylene-vinyl acetate copolymer/Montmorilionite) nano composite material, is intercalation configuration, and the mazy passage of formation makes that air moisture is difficult to pass through, and has good antisepsis, and is good flame retardant material.XPE is the processes for chemically crosslinked polyethylene foam material, is to add crosslinking agent and stabilizer with ldpe resin to form through high temperature is continuous foamed, compares with EPE (the physical blowing polyethylene is commonly called as PE Foam), and tensile strength is higher, and abscess is thinner.XPE is the desirable environment-friendly materials of automobile, air-conditioning insulation, and development as surfboard, moistureproof cushion, Yoga pad etc., also has certain purposes architectural rapidly on Leisure Sport articles for use market in recent years.Therefore utilize the superperformance of XPE to prepare to be applicable to the metallic conduit protection to use composite material, will have good market prospects.The utility model adopts the XPE of light and soft matter as thermal insulation layer, fit respectively in its both sides ethylene-vinyl acetate copolymer/Nano composite material of montmorillonite and hard XPE protective coating, because the existence of organic clay in ethylene-vinyl acetate copolymer/Nano composite material of montmorillonite, make the XPE stickiness of itself and thermal insulation layer very good; The XPE genus identical material of hard XPE and light and soft matter simultaneously, its fusion character and stickiness are also very good, so this composite protective material is extraordinary anticorrosion, the insulation of the coating performance of integral type, protection material.The thickness of trilaminate material can be looked Environmental Conditions and decide.
This composite protective material can be coiled material or tubing, is suitable for site operation.
The tubing form that the utility model is selected for use is tube wall one side opening, be to adopt to coat pipeline when construction, rather than the form of being inserted in pipeline, make to have good workability, and utilize external force that composite protective material is coated on the pipeline more closely, the sealing of opening side can be adopted heat weldable form.
The tubing form that the utility model is more selected for use is that outermost protective layer is longer than anticorrosion thin layer and thermal-protective coating on girth; when coating tube wall; can hold the outermost protective layer cage walls road of exerting oneself; the protective coating that grows simultaneously can twine the outside that is fitted in composite protective material, makes coating tighter.
This composite protective material also has following advantage:
(1) adiabaticity--the separated foam structure that it is trickle effectively reduces the energy interchange that cross-ventilation causes, and has antisweat concurrently, makes it extremely to be fit to the thermal insulating material of many wet environments.
(2) resiliency-thermal-protective coating can adopt the semi-rigid foaming body, is subjected to not lose reducing property behind the thump.
(3) sound absorption properties--have the absorbing sound and lowering noise function, be suitable for the sound-absorbing soundproof material in strong noise equipment such as automobile, motor, air-conditioning and the environment.(4) in addition, XPE is nontoxic, tasteless, the performance of resistance to chemical reagents, oil resistant, acidproof, anti-halogen and other all kinds of chemicalss, and is very easy to processing, can cut arbitrarily, as the material of New-generation efficient energy-saving, environmental protection vast potential for future development is arranged.
The utility model comprises the conveyance conduit of this composite protective material, it is a kind of metallic conduit that has coated composite protective material, two ends at conveyance conduit, adopt that an end metallic conduit stretches out, contract in the other end, this flexible mouthful design has the design of the long lines utilized, and makes the sealing between the conveyance conduit connection mouth very tight.With the metal pipe-wall contact layer be ethylene-vinyl acetate copolymer/Nano composite material of montmorillonite, the existence of organic clay, make it with also seamless with the stickup of built-in metal pipe, its composite protective material is coated on the tube wall closely, employing be convex table type lap seal form, make the coating performance of itself and pipeline very good, metallic conduit and external direct the contact have been cut off, its insulation, resistance is wet, the shock-absorbing antiseptic property is very good, has prolonged the working life of metal conveyance conduit.
