Accompanying drawing explanation
Fig. 1 is the sectional view of a kind of high performance and long service life plastic coated composite steel pipe of the utility model.
Embodiment
For making the purpose of this utility model, technological scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, the utility model provides a kind of high performance and long service life plastic coated composite steel pipe, comprises steel pipe 3, and the internal surface of described steel pipe 3 is at least provided with teflon coatings 4, and the outer surface of described steel pipe is at least provided with epoxy layer 2 and ASA coating 1; Described epoxy layer 2 is located between ASA coating 1 and steel pipe 3.
Concrete, described epoxy layer 2 outside is preferably covered one deck ASA coating 1, ASA coating 1 and is made up of ASA, ASA coating 1 is attached to steel pipe 3 outermost surface by epoxy layer 2, extend steel pipe working life at double, and ASA coating 1 has good processibility, operate simple and fast.
It should be noted that, ASA (English name: Acrylonitrile Styrene acrylatecopolymer) is by the rubber copolymerized macromolecular material of vinyl benzene, acrylonitrile and acrylic.ASA is thermostability engineering plastic, and its color stability is strong, is attached to steel pipe skin, not only moisture-proof, weather-proof in can expand the using scope of metal tube further, and aesthetic aspect is more rich and varied.
Epoxy layer 2 is made up of epoxy resin.There is natural affinity between epoxy resin and metal, not only serve as the bridging agent connected between ASA coating 1 and steel pipe 3, also do second corrosion protection and defense of resistance to impact for steel pipe 3.
And, be provided with epoxy layer 2 between ASA coating 1 and steel pipe 3, the thinner thickness of this epoxy layer 2, the expansion coefficient of steel pipe and ASA can be regulated, make between ASA and steel pipe, to realize tight compound.Like this, steel pipe skin obtains double shielding, and severe for Environmental Conditions, require the extreme environment such as shock-resistant, wear-resistant, corrosion-resistant, long service life, particularly mine, chemical enterprise, High Temperature High Pressure, this kind of tubing can play a role.
Teflon coatings 4 is made up of fluorinated ethlene propylene resin, and Teflon has very strong chemical inertness, in very wide temperature and frequency range, have lower permittivity.It is a kind of special plastic, has the features such as corrosion-resistant, wear-resistant, the large creep resistance of tensile strength, can be used in chemical device liner, fabricated metals inside and outside coating, cylinder surface layer and communication cable.
