Abstract

Thermosetting scratch-tolerant outdoor matt powder coating mainly comprises at least one epoxy-including resin, such as epoxy acrylic resin and epoxy resin, triglycidyl isocyanurate, and at least one carboxyl-including resin, such as carboxyl polyester resin and carboxyl acrylic resin. The invention has the advantages that compared with common outdoor matt powder coatings, the thermosetting scratch-tolerant outdoor matt powder coating features good scratch tolerance, gloss controllability, gloss that may be reduced to below 5% (measured at 60 DEG C) and the like; the preparation process of the coating of the invention uses supercritical carbon dioxide so that components of the coating are fluidized, and melt extrusion is achieved at low temperature.

Description

A kind of thermosetting scratch resistance open air low brightness paint powder and preparation technology thereof
Technical field
Coatings for furniture field of the present invention, particularly relates to its outdoor low smooth powder of a kind of thermosetting scratch resistance Coating and preparation technology thereof.
Background technology
Coating has in national economy and plays an important role, but the whole world is every year from painting The volatile organic matter being discharged in air that can issue in material has 10,000,000, is air master Originate, along with the enhancing of environmental consciousness, replace traditional with serious pollution solvent based coating to become Common recognition for entire society.
Summary of the invention
For solving above technology contents, the present invention provides: the outdoor low smooth powder of a kind of thermosetting scratch resistance End coating, mainly includes that at least one contains the resin of epoxy radicals such as epoxy radicals acrylic resin, ring Epoxy resins, triglycidyl isocyanurate and at least one carboxylic resin such as carboxyl polyester Resin, carboxyl acrylic resin, composition.
A kind of anti-whitening resistance powdery paints and preparation process thereof be:
(1) be added to agitating device after the various compositions of powdery paints being weighed is overcritical In fluid processing still；
(2) by material through spraying well granulation in classification still.
Beneficial effects of the present invention: compared with general outdoor low brightness paint powder, there is scratch resistance Good, gloss can control, and gloss can drop to 5% (measuring under 60 °) such as the following feature, additionally this Bright Paint preparation technology the supercritical carbon dioxide makes the various composition flows of coating, so The most just reach the effect melt extruded.
Detailed description of the invention
A kind of thermosetting scratch resistance open air low brightness paint powder, mainly includes that at least one contains epoxy radicals Resin such as epoxy radicals acrylic resin, epoxy resin, triglycidyl isocyanurate and extremely Few a kind of carboxylic resin such as carboxyl polyester resin, carboxyl acrylic resin, composition.
A kind of anti-whitening resistance powdery paints and preparation process thereof be:
(1) be added to agitating device after the various compositions of powdery paints being weighed is overcritical In fluid processing still；
(2) by material through spraying well granulation in classification still.
Beneficial effects of the present invention；Compared with general outdoor low brightness paint powder, there is scratch resistance Good, gloss can control, gloss can drop to 5% (measuring under 60 °) such as the following feature, additionally this Bright Paint preparation technology the supercritical carbon dioxide makes the various composition flows of coating, so The most just reach the effect melt extruded.
