CN104194556A - Powder paint for seaport instrument - Google Patents

Abstract

The invention discloses a powder paint for a seaport instrument. The powder paint is prepared from the following raw materials in parts by weight: 40-60 parts of E12 epoxy resin, 5-10 parts of triethylene tetramine, 0.5-1 part of triallyl cyanurate, 1-2 parts of isopropyl tri(dioctylpyrophosphato) titanate, 2-3 parts of bamboo charcoal powder, 7-10 parts of celestite powder, 1.3-2 parts of 2,6-di-tert-butyl-4-methylphenol, 0.2-1 part of zirconium fluoride, 0.1-0.4 part of 2,4,6-tri(dimethylaminomethyl)phenol and 10-13 parts of composite filler. A coating of the powder paint disclosed by the invention has a strong binding force with a base material; the power paint is high in mechanical strength, strong in impermeability, good in chemical stability and high in seawater corrosion resistance; and the coating is low in surface roughness, and the friction between the coating and a fluid is small, so that the damage to the coating can be reduced.

Description

Technical field

The present invention relates generally to a kind of coating, relates in particular to a kind of harbour instrument powder coating.

Background technology

Along with social development; the Working environment of various instruments becomes more complicated; vault, harbour, shaft bottom, deep water, tunnel, chemical industry factory site etc.; high low temperature variation, high pressure, HI high impact, high corrosion etc. have affected the normal use of this instrument greatly; and apply by efficient powder coating; can play good protection effect, reduce the spoilage of instrument.

Summary of the invention

The object of the invention is exactly for a kind of harbour instrument powder coating is provided.

The present invention is achieved by the following technical solutions:

A kind of harbour instrument powder coating, is characterized in that what it was made up of the raw material of following weight parts:

E12 epoxy resin 40-60, triethylene tetramine 5-10, triallyl cyanurate 0.5-1, sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester 1-2, bamboo charcoal powder 2-3, celestite powder 7-10,2,6-ditertbutylparacresol 1.3-2, Zirconium tetrafluoride 0.2-1,2,4,6-tri-(dimethylamino methyl) phenol 0.1-0.4, compounded mix 10-13;

Described compounded mix is made up of the raw material of following weight parts:

Laterite 30-40, wollastonite powder 10-14, attapulgite 8-10, process white 6-8, chitosan 2-3, cocounut oil 1-2, cyanacrylate 0.1-0.3;

Above-mentioned laterite, wollastonite powder, attapulgite are mixed, at 600-800 DEG C, calcine 2-4 hour, the cooling rear and process white mixed grinding of discharging, after being heated to 25-30 DEG C, cyanacrylate adds, 300-400 rev/min of dispersed with stirring 4-6 minute, adds chitosan, cocounut oil, fully ball milling, cross 100-120 mesh sieve, obtain described compounded mix.

A preparation method for powder coating for the instrument of harbour, comprises the following steps:

Above-mentioned bamboo charcoal powder, celestite powder are mixed, after stirring, add sec.-propyl three (dioctylphyrophosphoric acid acyloxy) titanic acid ester, stirring heating 4-6 minute at 60-70 DEG C, be cooled to normal temperature, add the each raw material of residue, by melt extruding in forcing machine, then after compressing tablet fragmentation, pulverize, sieve through pulverising mill again, obtain described harbour instrument powder coating.

Advantage of the present invention is:

The physical strength of powder coating coating of the present invention and the strong coating of base material bonding force self is high, and impermeabilisation ability is strong, and chemical stability is good, and the corrosion of seawater is had to very high resistance, and coatingsurface roughness is low, little with fluid friction, can reduce the infringement to coating.
