TABLE 2 test of the aging resistance of the paint films
Note: the above test was performed with reference to the national standard GB-T1865-2009.
In connection with examples 1-3, the UV setting time is related to the amount of acrylic modified emulsion and the amount of PEG-diacrylate. Under the action of ultraviolet light, acrylic acid modified emulsion and polyethylene glycol start to polymerize under the action of photoinitiator, and the more the addition amount, the shorter the complete polymerization time. Because the acrylic acid modified emulsion-polyethylene glycol diacrylate have good compatibility, the two blended polymer molecular networks can be mutually staggered to form an IPN network, thereby showing good physical and chemical properties.
Combining examples 1, 4 and 5, the more charcoal powder added, the longer the ultraviolet light irradiation setting time, because charcoal powder is porous structure, and the area irradiated by UV is reduced because part of the material enters the micropores, and thus more irradiation time is required for sufficient polymerization.
Combining with the embodiment 1, the embodiment 6 and the embodiment 7, the dosage of the photoinitiator has a relationship with the ultraviolet irradiation time for shaping the stone-like paint, and the more the dosage of the photoinitiator, the shorter the ultraviolet irradiation time, because the photoinitiator can promote the polymerization reaction of the acrylic modified emulsion and the polyethylene glycol diacrylate under the irradiation of light.
It will be understood by those skilled in the art that the foregoing is merely exemplary of the present invention, and is not intended to limit the invention to the particular forms disclosed, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
