Description
Technical field
The present invention relates to a kind of epoxy resin zinc-rich double antiseptic powder coating, belong to powder coating technology field.
Background technology
Anticorrosive paint is a kind of permanently effective coating used of energy under harsh corrosive environment, is prevented to reach coating
Rotten purpose, on the one hand needs the thick-film of coating, on the other hand to the surface of coating matrix resin and selection of auxiliary, base material at
Reason is also very stringent with coating decoration, maintenance requirement.It is before this kind of coating to use liquid coating, it usually needs multiple tracks application is just more
Requirement can be reached.
Powdery paints is that one kind is free of solvent, 100% solid powdery coating.With it is solvent-free, pollution-free, recyclable,
Environmental protection, save the energy and resource, reduce labor intensity with coating machinery intensity it is high the features such as.In recent years, powdery paints is pacified with it
The features such as overall height imitates, is pollution-free, in heavy antisepsis field, proportion is increasing.Currently, from double antiseptic powder coating raw material
Produce powder manufacture, the industrial chain of paint application is being formed.
The development of double antiseptic powder coating, the expansion of application field, the design also produced to raw material with power formulations carry
Many new requirements are gone out, single powder coating formulation can not meet the needs of not having to application, therefore, it is necessary to continually develop
New material and formula technique.
The content of the invention
