Description
Technical field:
The present invention relates to a kind of steel tank body, special-shaped pipeline, boats and ships, technique radiator inside and outside
The anti-corrosion material of ambient spray solidification, belongs to a kind of corrosion-proof epoxy powder liquid coating and preparation thereof
Method.
Background technology:
Currently, at home in each oilfield construction, for steel tank body, special-shaped pipeline, boats and ships,
Technique radiator inside and outside antiseptical material is a lot, but coating can be as electrostatic spraying corrosion-proof epoxy
End coating antiseptic effect, again can ambient spray solidification anti-corrosion material little.Particularly to oil
Field oil storage, water storage tank body, the application aspect of boats and ships ectosome, be suitable for the high-quality of ambient spray solidification
The anticorrosive paint of amount is less.Owing to the antiseptic effect of generally acknowledged electrostatic spraying powder coating is fine,
But it is only used for steel pipeline anti-corrision, if for steel tank body, boats and ships, special-shaped pipeline, heating installation
The anticorrosions such as sheet, it is impossible to solve to add hot-melt problem.If wanting to be applied to steel tank body and different
The anticorrosion of type pipeline, boats and ships etc., is necessary for using a kind of novel process to make powdery paints energy room temperature
Solidification, had both met the requirement of aseptic technic, also can reduce production cost, solved preventing in application
Detritus amount.
Summary of the invention:
In order to solve the problem that technical background exists, the present invention proposes a kind of corrosion-proof epoxy powder liquid
Body coating and preparation method thereof.This coating not only solves epoxy powder room temperature brushing solidification and asks
Topic, and improve adhesive force and the flexility of coating, make coating be provided with good anticorrosion
Effect, has again the highest shock resistance, case hardness and anti-wear performance, is a kind of anticorrosion work
Skill is easy, the preferable anticorrosive paint of favorable anti-corrosion effect.
The technical scheme is that this corrosion-proof epoxy powder liquid coating is by following raw materials according system
, following raw materials by weight ratio: modified epoxy anti-corrosive powder paint 100 parts, amine
Cross-linking agent 0.3～1.0 parts, surface finishing agent methyl-silicone oil 1.0～4.0 parts, plasticiser 2.0～
4.0 parts, ketones solvent 130～160 parts.
In such scheme, amine cross-linking agent is ethylenediamine or hexamethylene diamine.Plasticiser is phthalic acid
Dibutyl ester or dioctyl phthalate.
The preparation method of the corrosion-proof epoxy powder liquid coating of such scheme comprises the following steps: head
First modified epoxy anti-corrosive powder paint is put in dissolving tank according to quantity, add ketones solvent, stir
Mix uniformly, soak and dissolve 10～20min, after being stirred for 5～10min, add amine crosslinking
Agent, surface finishing agent methyl-silicone oil, plasticiser mix and blend 10min, then high speed dispersion 20min,
Corrosion-proof epoxy powder liquid coating is obtained with the sieves of 100～140 mesh after filtering.
The bubble that in such scheme, surface finishing agent methyl-silicone oil is formed when can eliminate film forming；Modified
Epoxide powder coating is Patent No. 201010221871.8, entitled a kind of Wear-resistant, high-temperature resistant
The concrete application of the inside and outside anti-corrosive powder paint of steel pipe；Cross-linking agent ethylenediamine, hexamethylene diamine energy
Promote liquid coating normal temperature cure；Plasticiser dibutyl phthalate, phthalic acid two are pungent
Ester can make film plasticizing softening have flexibility.
There is advantages that this coating not only solves epoxy powder room temperature brushing
Problem of solidification, and improve adhesive force and the flexility of coating, make coating be provided with very well
Antiseptic effect, have again the highest shock resistance, case hardness and anti-wear performance, be a kind of
Anticorrosion process is easy, the preferable anticorrosive paint of favorable anti-corrosion effect.Corrosion-inhibiting coating after solidification has
With electrostatic spraying powder coating coating equivalent effect, superpower adhesive force, fine case hardness,
Resisting strong impact, bending resistance and weatherability.Solve steel tank body and special-shaped pipeline, boats and ships,
Employing electrostatic spraying corrosion-proof epoxy powder coating antiseptical cannot be heated in technique radiator etc. difficult
Topic.Using corrosion-proof epoxy powder liquid coating anticorrosion, its coating process is simple, film after solidification
With electrostatic spraying anticorrosive powder coating, antiseptic effect is the best, not only increases corrosion-inhibiting coating and makes
With the life-span, and normal temperature cure reduces production cost, has saved production capital.
