The coating (finish paint) that embodiment 1-4 is prepared according to《HGT 4104-2009 watersoluble fluorine paints for building》Or
《JG210-2007 building inside and outside wall priming paint》Requirement, it is necessary to test plate (panel) in coating drying time, two projects of contrast ratio
Brush an aspect paint, 100 μm of wet-film thickness;Sundry item is needed to test plate (panel) brushing two-layer finish paint, and wet-film thickness is respectively 120 μm
With 80 μm.Due to the limitation of coating apparatus specification, can unify from 100 μm of bar spreader coatings.Internal layer finish paint is in (23 ± 2)
DEG C, conserve 1 day in the environment of (50 ± 5) % humidity;Outer layer finish paint is conserved in (23 ± 2) DEG C, the environment of (50 ± 5) % humidity
7 days.
Test plate (panel) after brush finish is tested according to main performance index and standard described in table 1.
Table 1FEVE top coats main performance index (HGT_4104-2009_ watersoluble fluorine paint standards for building)
Experimental result is as shown in table 2:
Table 2:The performance test result of embodiment of the present invention coating
The FEVE fluorocarbon coatings prepared using inventive formulation are can be seen that by above-mentioned performance test to stir in a reservoir
Uniform after mixing without lump, low-temperature stabilization never degenerates, and the drying and forming-film time only needs 0.5 hour, and adhesive force is strong, acidproof, alkaline-resisting, resistance to
Water, wet-heat resisting, washability, stain resistant, UV resistant, properties reach at or above professional standard, especially humidity resistance
Matter and acid-proof alkaline are very good.
Purchase commercial solvents type fluorocarbon coating SW3625 and aqueous fluorocarbon coating SW9301, carry out parallel performance test.Knot
Fruit is shown in Table 3:
Table 3:Solvent-borne type fluorocarbon coating SW3625 and aqueous fluorocarbon coating SW9301 performance test results
According to table 3 and the performance test results of table 4, it can be clearly seen that, FEVE fluorocarbon coatings of the invention adhesive force,
Alkali resistance, acid resistance, wet-hot aging performance, contaminated resistance and UV resistant aspect are better than solvent-borne type fluorine common in the market
Carbon coating SW3625 and aqueous fluorocarbon coating SW9301.
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should be all considered as belonging to of the invention
Protection domain.
