By the powdery paints prepared by embodiment 1-4 and comparative example 1-4, applied according to a conventional method to indoor decoration
Material, then be tested for the property, test result is as in the table below：
1 the performance test results of table
It is analyzed from the result of embodiment 1- embodiments 4, the powdery paints that the present invention prepares is applied to actual production
When in journey, weatherability >=1500h, coating is more smooth than relatively thin (film thickness≤40 μm) and surface, three-dimensional sense is strong, and glossiness is good
(more than 87) have preferable impact (50cmkg) and folding test result (more than 3mm)
From embodiment 3 and the testing result of comparative example 1, it can be seen that modified petchem is as in metal powder
Important substrate, the modified petchem of the preparation that comes by using alcoholysis and acidolysis can improve preparing metal and significantly carry
High/low temperature toughness and humidity resistance improve the impact of coating, folding test and weatherability.
From embodiment 3 and the testing result of comparative example 2-4, it can be seen that when there is no hindered amine light stabilizers and Asia
During phosphate antioxidant, the performance of coating is significantly substantially reduced (gloss is reduced to 55, weatherability and is reduced to 600h), when only depositing
In hindered amine light stabilizer or phosphite antioxidant, the performance of coating has the reduction of certain amplitude, and (gloss is reduced to 73
Left and right, weatherability are reduced to 750h), when all there are when hindered amine light stabilizer and phosphite antioxidant, each side of coating
The performance in face obtains more apparent promotion, and the analysis of causes is as follows：
Hindered amine light stabilizer can prevent the photochemical degradating of polymer molecule by closing activity center, be obstructed
Amine light stabilizer is a kind of free agent capturing agent, by capturing free radical, hydroperoxide decomposition, quenching excited state energy
Reach age inhibiting purpose, with reference to the use of phosphite antioxidant, the two plays synergistic effect, can be provided for coating as
Anti- gloss reduction, anti-decomposition, anti-dropout, Anti- tarnishing etc. are preferably protected.
