Description

A kind of fire resistant anticorrosive organic coating
Technical field
The present invention relates to a kind of coating, specifically for the fire resistant anticorrosive organic coating closing gold sprayed coating hole.
Background technology
The application of plasma spray technology, it it is an important application in material protection and field of surface technology, by carrying out thermal spraying at material surface, form alloy coat, material is formed protection coating, but owing to conventional plasma spray technology is due to the reason of technology itself, it is hardly formed fully dense alloy coat, the existence of hole is for the anti-wear performance gain to some extent of gold sprayed coating, because hole can effectively reduce the friction being coated with interlayer, but for corrosion-resistant be but a big defect, we should reduce the hole of coating as much as possible, to reach acid, alkali, the purpose that salt completely cuts off with base material.
Currently there are hole sealing agent ubiquity poor heat resistance, cost high, to bad environmental, be necessary existing technology is improved for these problems.
Summary of the invention
The purpose of the present invention is just for solving the defect that prior art exists, it is provided that a kind of energy is high temperature resistant, the fire resistant anticorrosive organic coating of low cost, environmental sound.
To achieve these goals, the present invention adopts the following technical scheme that
A kind of fire resistant anticorrosive organic coating, it includes following raw materials by weight portion preparation gained:
Component A: modifying epoxy resin by organosilicon: 40-65;Glass powder with low melting point: 10-30;Mica powder: 6-15;Flake asbestos: 3-15;White carbon black: 2-6;Nano silicon: 1-4;KH-560:1-4;
B component: aromatic amine curing agent: for the 1-5 ‰ of component A gross weight;DMP-30: for the 3-12% of the weight of aromatic amine curing agent.
Described modifying epoxy resin by organosilicon is one or more in epoxy resin 900, epoxy resin 1000, epoxy resin 1200.
This coating adopts modifying epoxy resin by organosilicon for substantially to add materials, therefore it has good heat resistance energy and acid-proof alkaline, glass powder with low melting point is that softening temperature is at about 400 degree, it can the hot mastication of 400 degree form enamel shape coating and so-called two-step film forming with modifying epoxy resin by organosilicon and other color stuffings again, when organic-silicon-modified resin decomposed in the case of a high temperature, coating can be allowed to bear more persistently even higher temperature;Mica powder can significantly improve paint film intensity and resistance to chalking;The heat stability of flake asbestos is high, and can improve the crack resistance under paint film high temperature;White carbon black mainly makees black pigment, and has good thermostability;Nano silicon can quickly form network structure, improves the ageing-resistant performance of paint film, paint film intensity, fineness etc..Nano material forms the coating of densification can improve impermeability and anti-ultraviolet absorption, anti-heat ageing ability.KH-560, as connecting organic with inorganic bridge, plays the effect increasing bond strength, simultaneously works as the moistening and good dispersibility to nanometer color stuffing.B component aromatic amine curing agent, carry out crosslinking curing film forming with organic-silicon-modified resin;DMP-30 is curing accelerator, shortens hardening time.
Beneficial effects of the present invention:
Coating provided by the invention, heat-resist, cost is low, easy to operate, environmental sound, changes coating formula and allows to adopt different forms of construction work, cold spray, brushing, roller coat, can obtain great efficiency of construction in certain scope.
