Description
Technical field
The present invention relates generally to a kind of coating, particularly relates to a kind of polyethylene powder coating used for anti-corrosion steel pipe.
Background technology
Powder coating, as environmental protection, energy-conservation, economic, efficient product, replaces liquid paint gradually, becomes tempo and the fastest coating new technology of scale.In current art of powder coatings, be all common indoor decorative powder coating or outdoor weatherability powder coating substantially.Functional powder coating also relates to the fields such as epoxy heavy antisepsis type, conductivity type, insulated type, the type of resistance to combustion, scumbling type, therefore studies novel high-performance powder coating and can play better booster action for nation-building, social life.
Summary of the invention
The object of the invention is exactly to provide a kind of polyethylene powder coating used for anti-corrosion steel pipe.
The present invention is achieved by the following technical solutions:
A kind of polyethylene powder coating used for anti-corrosion steel pipe, is characterized in that what it was made up of the raw material of following weight parts:
Polyvinyl resin 80-100, EVA resin 2-4, N cyclohexyl N' phenyl P phenylene diamine 0.2-0.3, iron oxide red 1-2,2-amino-2-methyl-1-propanol 2-3, sodium silicoaluminate 1-2, butyl methacrylate 2-4, Fluorspar Powder 4-10, wilkinite 1-2, four [β-(3,5-di-tert-butyl-hydroxy phenyl) propionic acid] pentaerythritol ester 1-2, compounded mix 10-13;
Described compounded mix is made up of the raw material of following weight parts:
Gibbsite 10-20, laterite 30-40, aluminium nitride 4-6, sodium silicate 3-4, ricinolic acid 1-2, oxidized polyethlene wax 3-4, lead sulfate tribasic 0.1-0.2;
By above-mentioned laterite, gibbsite mixing, 3-5 hour is calcined at 500-600 DEG C, after discharging cooling, mix with aluminium nitride, sodium silicate, lead sulfate tribasic, add suitable quantity of water grinding, the hydrochloric acid adding 10-20% regulates PH to be 4-5, being heated to system temperature is 70-90 DEG C, and being ground to fineness is 300-400 order, and repeated hydrogenation sodium oxide is adjusted to neutrality, spraying dry, obtains powder; Mixed with other remaining component by gained powder, namely grinding evenly obtains described compounded mix.
A preparation method for polyethylene powder coating used for anti-corrosion steel pipe, comprises the following steps:
After above-mentioned each raw material mixing, melt extrude under input forcing machine, air-cooled, pulverize in pulverizer, then abrasive dust, cross 180-200 mesh sieve, obtain described polyethylene powder coating used for anti-corrosion steel pipe.
Advantage of the present invention is:
Polyethylene powder coating of the present invention and metal base have good tack, and film is tough and tensile stable, not easy to crack, anticorrosion good weatherability, long service life.
