Description
Technical field
The present invention relates to coating research and preparing technical fields, are related to petrochemical industry and to steel construction in the item that can be kept the temperature
There is the protective coating of antisepsis again under part, specifically, being a kind of thick coated type epoxy insulation antiseptic paint.
Background technology
Global energy crisis promotes the research and development of power-saving technology, and power-saving technology advances heat preservation technology
In the commonly used of petrochemical industry, heating pipeline etc..The effect of heating pipeline insulating layer is to block scattering and disappearing for hot-fluid, is adopted
Thermal insulation material is glued by calcination of minerals again mostly to be process.Due to containing a large amount of inorganic salts in mineral, mine is used
Thermal insulation material made of object still contains the corrosive deposits such as a large amount of chloride, sulfide；On the other hand, the thermal insulation material is usual
For porous structure, there are larger surface area and abundant capillary, thus, they have stronger adsorption capacity and water imbibition
Can, in the case of rain leakage or condensation of moisture, the alkaline soluble materials such as chlorion in insulating layer form electrolyte can be with water
The surface that steel pipeline is contacted with oxygen, causes the corrosion of heating pipeline metal surface.Since this corrosion is to be happened at heat preservation
Under layer, it is difficult discovery and on-call maintenance at the initial stage of corrosion, is often had occurred and that when heating pipeline has corrosion until realizing
Leakage causes accident.Therefore, it in petrochemical industry, is lost caused by the corrosion failure under heating pipeline insulating layer every year
Very huge, this is the thing that should be paid special attention to.
Currently, the anti-corrosion and heat preservation to heating pipeline are usually made of two parts system：First, in heating pipeline metal watch
Face coats corrosion-inhibiting coating；Then, thermal insulation material is used to carry out adiabatic heat-insulation to pipeline and equipment again on corrosion-inhibiting coating.Anti-corrosion and
The implementation of heat insulating work is more complicated, and not only progress is slow, and human cost is also higher.Further, since difficult when pipeline assembly connects
The crack and gap exempted from easily cause the infiltration of rainwater, this leaves hidden danger for the corrosion of metallic conduit under insulating layer.Therefore, simple
Chemoprevention corruption heat preservation method, reduces the generation of constructional deficiency, improves anti-corrosion and the long-term barrier propterty of insulating layer, becomes petrochemical industry
And heat distribution pipeline application field urgent problem to be solved.
Invention content
It is an object of the invention to solve the above problems, a kind of thick coated type epoxy insulation antiseptic paint is provided, it uses resistance to height
Warm modified epoxy, as film forming matter, contains hollow glass microballoon, flake light talcum with heat resistant polyamide curing agent
Powder and basalt fibre；The architectural characteristic that hollow glass microballoon can be utilized reduces impact of the hot-fluid to paint film；Meanwhile utilizing piece
Stepped construction of the shape lightweight talcum powder in paint film extends corrosive medium and penetrates into the path of metal substrate from coating surface and ooze
The saturating time to ensure paint film while can be resistant to high temperature ageing impact for a long time, and has good corrosion resistance；This
Outside, it reinforces paint film using inorganic basalt fibre, and so that coating is had preferably, high film thickness construction and high temperature resistant are resistance to
Cracking performance can preferably solve the heat preservation of metal structure and corrosion-resistant two fold problem under high temperature.The insulation antiseptic paint of the present invention
It with good antiseptic property and certain heat-insulating property, can apply, and easy construction, be suitble at a temperature of room temperature is to 150 DEG C
