Abstract
The invention relates to a hydroxyalkyl amide curing agent composition used for powder coating. The hydroxyalkyl amide curing agent composition used for powder coating comprises the following components in percentage by weight: 65-90% of hydroxyalkyl amide curing agent, 4-20% of anti-yellowing agent and 5-18% of degassing agent. The hydroxyalkyl amide curing agent composition is prepared by adopting a melting mixing or melting extruding method. The anti-yellowing agent is a phosphate ester anti-yellowing agent or 2-hydroxyl-4-methoxy diphenyl ketone or 2-hydroxyl-4-n-octyl oxy diphenyl ketone, and the degassing agent is polyethylene wax. The hydroxyalkyl amide curing agent composition is directly used in a powder coating formula, three components are respectively added according to the formula and are mixed, so that the obtained hydroxyalkyl amide curing agent composition product has better film yellowing resistant performance and film needle hole resistant performance.
Description
Technical field
The invention belongs to solidifying agent, be specifically related to a kind of hydroxyalkyl amide curing agent composition for powder coating.
Background technology
The powder coating of traditional use amide hardener, there is the serious problem of powder coating orange peel in majority, the aqueous vapor that discharges in the solidify reaction process simultaneously can not be discharged effectively, and the coating pin-hole phenomena is serious, has greatly affected promoting the use of of hydroxyalkyl amide cured powder paint.The coating leveling of powder coating improves to some extent in the at present external like product, but the pin hole problem of coating and discoloration problem still do not solve fully.
Summary of the invention
The object of the present invention is to provide a kind of hydroxyalkyl amide curing agent composition for powder coating, said composition is directly used in the powder coating prescription, with add respectively above-mentioned three kinds of compositions in when prescription and compare, products obtained therefrom has better anti-xanthochromia and the anti-pin hole performance of filming of filming.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of hydroxyalkyl amide cured article composition for powder coating, composed of the following components by weight percentage: hydroxyalkyl amide solidifying agent 65-90%; Anti-yellowing change agent 4-20%; Air release agent 5-18%.
Preferably, composed of the following components by weight percentage: hydroxyalkyl amide solidifying agent 80-90%; Anti-yellowing change agent 5-12%; Air release agent 5-10%.
The preparation of described composition is adopted melting mixing or is melt extruded method.
Described anti-yellowing change agent is the anti-yellowing change agent of phosphorous acid esters.
Described anti-yellowing change agent is ESCALOL 567 or Octabenzone.
Described air release agent is polyethylene wax.
The invention has the beneficial effects as follows: hydroxyalkyl amide curing agent composition of the present invention is directly used in the powder coating prescription, and adds respectively above-mentioned three kinds of compositions when the prescription and compare, products obtained therefrom has better anti-xanthochromia and the anti-pin hole performance of filming of filming.
Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.
