Abstract
The invention discloses a high-hardness polyester resin powder coating. The high-hardness polyester resin powder coating is prepared from the following raw materials in parts by weight: 50-60 parts of saturated carboxyl-terminated polyester resin, 6-10 parts of triglycidyl isocyanurate, 1-2 parts of beta-hydroxyalkylamide, 1-2 parts of red iron, 0.1-1 part of titanium dioxide, 1-2 parts of benzotriazole, 5-10 parts of vermiculite powder, 1-2 parts of sodium fluoride, 1-2 parts of 1,4-cyclohexanedimethanol and 7-10 parts of composite filler; the powder coating disclosed by the invention has the advantages of high surface hardness, good leveling property, smooth hand feel, good mechanical properties such as impact resistance and good protection effect on the base material.
Description
Technical field
The present invention relates generally to a kind of coating, relates in particular to a kind of high rigidity polyester resin 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 high rigidity polyester resin powder coating is provided.
The present invention is achieved by the following technical solutions:
A kind of high rigidity polyester resin powder coating, is characterized in that what it was made up of the raw material of following weight parts:
Saturated terminal carboxyl polyester resin 50-60, isocyanuric acid three-glycidyl ester 6-10, β-hydroxyalkyl amide 1-2, iron oxide red 1-2, titanium dioxide 0.1-1, benzotriazole 1-2, vermiculite power 5-10, Sodium Silicofluoride 1-2, Isosorbide-5-Nitrae-cyclohexanedimethanol 1-2, compounded mix 7-10;
