Abstract
The invention relates to a coating, and particularly relates to a high-temperature-resistant anticorrosive organic coating for pores of closed gold spraying coats. The high-temperature-resistant anticorrosive organic coating is prepared from the following raw materials in parts by weight: a component A consisting of 40-65 parts of organic silicone modified epoxy resin, 10-30 parts of low-melting-point glass powder, 6-15 parts of mica powder, 3-15 parts of asbestos powder, 2-6 parts of carbon black, 1-4 parts of nano silica and 1-4 parts of KH-560, and a component B consisting of an aromatic amine curing agent accounting for 1-5% of the total weight of the component A and DMP-30 accounting for 3-12% of the weight of the aromatic amine curing agent. The coating provided by the invention is good in heat resistance, low in cost, convenient to operate, and harmless to the environment; the proportioning of the coating is changed within a certain range, and different construction modes such as cold spraying, brushing and roller painting are allowed to be adopted, so that great construction efficiency can be achieved.
Description
Technical field
The present invention relates to a kind of coating, specifically for the fire resistant anticorrosive organic coating that seals golden sprayed coating hole.
Background technology
The application of hot-spraying techniques, it is an important application in material protection and sufacing field, by carrying out thermospray at material surface, form alloy coat, material is formed to supercoat, but due to the reason of conventional hot-spraying techniques due to technology itself, be difficult to form fully dense alloy coat, the existence of hole gains to some extent for the wear resisting property of golden sprayed coating, because hole can effectively reduce the friction that is coated with interlayer, but for corrosion-resistant be but a large defect, we should reduce the hole of coating as much as possible, to reach acid, alkali, the object that salt and base material are isolated.
Exist in the market hole sealing agent ubiquity poor heat resistance, cost high, harmful to environment, for these problems, be necessary existing technology to improve.
Summary of the invention
The defect that object of the present invention exists for solving prior art just, provides that a kind of energy is high temperature resistant, low-cost, the fire resistant anticorrosive organic coating of environmental sound.
To achieve these goals, the present invention adopts following technical scheme:
A fire resistant anticorrosive organic coating, it comprises following raw materials by weight portion preparation gained:
A component: modifying epoxy resin by organosilicon: 40-65; Glass powder with low melting point: 10-30; Mica powder: 6-15; Asbestos powder: 3-15; Carbon black: 2-6; Nano silicon: 1-4; KH-560:1-4;
B component: aromatic amine curing agent: be the 1-5 ‰ of A component gross weight; DMP-30: be 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 adding materials, therefore it has good heat resistance energy and acid-proof alkaline, glass powder with low melting point is that softening temperature is in 400 degree left and right, it can be again 400 degree hot mastications and to form enamel shape coating with modifying epoxy resin by organosilicon and other color stuffings be so-called two-step film forming, can under high-temperature condition, during decomposed, allow coating bear more lasting even higher temperature at organic-silicon-modified resin; Mica powder can significantly improve paint film intensity and resistance to chalking; The thermostability of asbestos powder is high, and can improve the resistance to cracking under paint film high temperature; Carbon black is mainly to make black pigment, and has good thermotolerance; Nano silicon can form reticulated structure fast, the ageing-resistant performance of raising paint film, paint film intensity, smooth finish etc.Nano material forms fine and close coating can improve that impermeability and antiultraviolet absorb, anti-thermal ageing ability.KH-560, as connecting organic and inorganic bridge, plays the effect that increases bonding strength, plays the moistening and good dispersive ability to nanometer color stuffing simultaneously.B component aromatic amine curing agent, carry out crosslinking curing film forming with organic-silicon-modified resin; DMP-30 is curing catalyst, shortens set time.
Beneficial effect of the present invention:
Coating provided by the invention, good heat resistance, cost are low, easy to operate, environmental sound, change coating formula and allow to adopt different forms of construction work in certain scope, and cold spray, brushing, roller coat, can obtain great operating efficiency.
