Abstract
A kind of high pressure resistant conductive anti-corrosion coating of heatproof of the present invention, contain two kinds of components of A, B, component A contains: novolac epoxy resin, organosilicon epoxy hybrid resin, the polymer defoaming agent without organosilicon, the polymer copolymerization body of affinity groups containing pigment dispersing agent, hydrophobicity aerosil, modified zinc phosphate, aluminium triphosphate, sheets of conductive mica powder, carbon nanotube, talcum powder, titanium dioxide, dimethylbenzene and n-butanol, B component contains: Solvent-free Modification cycloaliphatic amines, aminoalkoxysilane, and when construction is mixed by weight.It surface of the invention can be low, hydrophobic function with " lotus leaf effect ", fouling in crude oil pipeline and storage tank, wax deposition phenomenon can be reduced, it reduces power consumption, reduce residue cleaning difficulty in storage tank, a kind of special coating is provided for conveying crude oil metallic conduit and the high pressure resistant conductive corrosion-resistant demand of crude oil storage tank inner wall heatproof, provides a kind of new guarantee for oil extraction.
Description
Technical background
The present invention relates to industrial coating technical fields, are a kind of in possible generation accumulation electrostatic problem and tool specifically
The heatproof for having certain delivery temperature, the conveying crude oil metallic conduit of discharge pressure and crude oil storage tank inner wall to use is high pressure resistant conductive anti-
Rotten coating.
Background technique
The development of modern industry can encounter many problems, and be grown up in continuous solve the problems, such as.Many
In problem, electrostatic problem is increasingly becoming petroleum, petrochemical industry, chemical industry, ship, weaving, papermaking, printing, rubber, plastics, pharmacy, electricity again
The new problem that almost each industrial circle and the departments such as explosives, inflammable items production and storage and transportation are perplexed such as son, national defence.Electrostatic
Problem or will also continue to bring different degrees of harm to these industrial circles and department, it forces people to have to handle
Attention turn back to this ancient subject and once the problem of, prevent the research of electrostatic hazard also and just become safety at present and is raw
One of the important research content that production, pre- calamity are taken precautions against natural calamities.
For industrial coating field, occur a variety of different static conductive coatings at present.But face oil extraction row
Industry is no longer limited to the condition of common normal pressure conveying and normal temperature storage in face of conveying crude oil and crude storage, and needing to use has
The case where very high discharge pressure or storage temperature higher crude oil, needing can prevent electrostatic from generating but also bearing one
The high pressure resistant conductive anti-corrosion coating of heatproof that the Crude Oil Transportation metallic conduit and crude oil storage tank inner wall of constant-pressure and higher temperature use.
Research and development and manufacturing enterprise as industrial coating ought to carry out studying with regard to this and provide product good accordingly for market.
Summary of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of high pressure resistant conductive anti-corrosion coating of heatproof, it
The requirement that Crude Oil Transportation metallic conduit and crude oil storage tank inner wall with certain pressure and higher temperature use should be able to be met, prevented
Electrostatic problem causes damages to Crude Oil Transportation metallic conduit and crude oil storage tank, provides guarantor for the safety in production of oil exploitation industry
Barrier.
To achieve the above object, this invention takes following technical schemes.
A kind of high pressure resistant conductive anti-corrosion coating of heatproof contains two kinds of components of A, B, which is characterized in that the weight of the component A
Percentage are as follows:
The weight percent of the B component are as follows:
Solvent-free Modification cycloaliphatic amines 72.5%~75.5%；
Aminoalkoxysilane 24.5%~27.5%；
The component A is mixed in construction by weight A:B=100:12.2~18.6 with B component.
Further, the epoxide equivalent of the novolac epoxy resin is 168~178 (g/eq).
Further, the epoxide number of the organosilicon epoxy hybrid resin is 0.02~0.07.
Further, the sheets of conductive mica powder is using SnO2/Sb203Coat, piece diameter is that 50~70 microns of micas are multiple
Close conductive powder body.
Further, the carbon nanotube is ultralow impurity single-walled carbon nanotube.
Further, the solid content of the Solvent-free Modification cycloaliphatic amines is greater than 99%, and active hydrogen equivalent weight is 70~80.
Further, the aminoalkoxysilane is difunctional silane-primary amino group with reactivity and hydrolyzable
Triethoxysilyl, reactive duality use it can as crosslinking agent, also can be as the adhesion promotion of coating
Agent.
A kind of good effect of the high pressure resistant conductive anti-corrosion coating of heatproof of the present invention is:
It (1) is resistance to certain delivery temperature, the conveying crude oil metallic conduit of discharge pressure and crude oil storage tank inner wall heatproof
High-pressure conductive corrosion-resistant demand provides a kind of high pressure resistant conductive anti-corrosion coating of heatproof, can be the safety in production of oil exploitation industry
A kind of new guarantee is provided.
(2) surface of the high pressure resistant conductive anti-corrosion coating of heatproof of the invention can be low, has the hydrophobic of similar " lotus leaf effect "
Function can reduce crude oil and the phenomenon that fouling, wax deposition, can be reduced power consumption during operation during conveyance conduit and storage tank oil storage
With the difficulty for reducing storage tank cleaning residue.
(3) erosion resistant coating of the high pressure resistant conductive anti-corrosion coating of heatproof of the invention can not only eliminate crude oil and produce during transportation
Raw electrostatic, and can also be 10MPa, crude oil coating under high temperature transport condition in discharge pressure be not in blistering and cracking
The phenomenon that, belong to a kind of high pressure resistant conductive anti-corrosion coating kind of effective heatproof.
Specific embodiment
A kind of specific embodiment of the high pressure resistant conductive anti-corrosion coating of heatproof of the present invention is given below, provides 3 embodiments.
It should be understood that implementation of the invention embodiment not limited to the following.
