Abstract
The utility model claims a corrosion-proof tightening piece comprising a tightening piece body being in a three-layer composite structure, wherein the three layers are a Teflon coating layer, a transition layer and a metal bottom layer from top to bottom. The Teflon coating layer of the corrosion-proof tightening piece has low friction, high adhesion, excellent wear prevention and scrape resistance; after being coated with the Teflon coating layer on the external surface, the tightening piece has enhanced corrosion-proof performance, meets the corrosion-proof requirements to the product surface in various circumstances; the adhesive resin is used as the transition layer to substitute the conventional glue to make the adhesion between the Teflon coating layer and the metal bottom layer.
Description
Technical field
The utility model relates to a kind of anticorrosion fastening piece that can be applicable to various strong acid-base rugged environment.
Background technique
The antiseptic property of fastening piece is as an important indicator of offshore oil pipeline system assembly; Extensive application is in the oil transportation system and bringing into play crucial effects; The fastening piece antiseptic property is not up to standard; In case be corroded, the sealing of whole pipeline system also can be affected thereupon, thereby causes the leakage of liquid to cause economic loss without redemption possibly.Environment requires the increasingly high of also change to the antiseptic property of product.Therefore, under different working environments, how to make the antiseptic property of product more superior and be useful in various rugged environments, just having become needs the problem that solves on the engineering.Common traditional anticorrosion process has: coating is painted, is smeared rust preventive oil, oxidation, metallizing coating or the like, but the antiseptic effect of these technologies is all unsatisfactory, but also has increased the workload and the cost of construction department greatly.
The model utility content
The purpose of the utility model just is to provide a kind of anticorrosion fastening piece, can better be anticorrosion.
The technological scheme of the utility model is: a kind of anticorrosion fastening piece, comprise the fastening piece body, and the fastening piece body is a three-layer composite structure, is followed successively by sharp fluorine long paint layer, transition layer and metal back layer from top to bottom.
As preferably, the thickness of said metal back layer is 5-25 μ m, and the thickness of said sharp fluorine long paint layer is 15-25 μ m.
As preferably, the material of said transition layer is an adhesion resin.
Compared with prior art; The beneficial effect of the utility model is: sharp fluorine long paint layer has low frictional properties, close adhesion, superior abrasionproof and undermines characteristics such as anti-drawing together property; The outer surface of fastening piece body be coated be covered with this coating after; Improved the antiseptic effect of fastening piece, can satisfy the corrosion resistance requirement of varying environment product surface; Through using adhesion resin to substitute glue commonly used, make that the cementability of sharp fluorine long paint layer and metal back layer is better as transition layer.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
To combine accompanying drawing that the utility model is described further below.
A kind of anticorrosion fastening piece as shown in Figure 1 comprises the fastening piece body, and the fastening piece body is a three-layer composite structure, is followed successively by sharp fluorine long paint layer 1, transition layer 2 and metal back layer 3 from top to bottom.As preferably, the thickness of said metal back layer 3 is 5-25 μ m, and the thickness of said sharp fluorine long paint layer 1 is 15-25 μ m; The material of said transition layer 2 is an adhesion resin.
Claims (3)
1. an anticorrosion fastening piece comprises the fastening piece body, it is characterized in that: the fastening piece body is a three-layer composite structure, is followed successively by sharp fluorine long paint layer, transition layer and metal back layer from top to bottom.
