Contrast sample 2 | 150 | 0.021 | 2.6 | 24 | F |
(1) pencil hardness is as the criterion to scratch.
Embodiment 1-7 brief summary:
(1) Acetacetic acid alkyl ester and inner complex thereof are synthetic simple, and productive rate is higher, are fit to the needs of large-scale commercial production.
(2) the Acetacetic acid alkyl ester cobalt chelates can be dissolved among the resin that contains siccative oil, such as Synolac, also dissolves in some conventional solvents, has brought convenience for it is used for water-based system coating.
(3) Acetacetic acid alkyl ester cobalt chelates siccative and traditional siccative such as cobalt iso-octoate have the similar dryness energy of urging.
Embodiment 8
The Acetacetic acid alkyl ester cobalt chelates is urged dried application experiment in water-base resin:
Used water-base resin is HD-E50 water-base epoxy ester (sharp heavy chemicals company limited, the solid content 40% used of Beijing Jin Hui).The siccative addition is 0.4% (urging dried metal quality to resin solid part quality).
Because there is no the judgement criteria that corresponding water-base resin is urged the dryness energy in the existing national standard, the present invention will adopt the method for following provisions:
1) surface drying of filming: after adding siccative in the water-base epoxy ester, varnish is diluted to solid content 20% with deionized water.With the spraying or standard blade coating device blade coating on 70*150mm detin layer tinplate, coating thickness is controlled between the 20--25 μ m, making sheet and the performance evaluation of filming are all finished in 23 ℃ ± 1 ℃ thermostatic chamber.Surface drying time is finished from making sheet and is begun to calculate, and concrete grammar touches dry method with reference to the finger among the GB1728-79.
2) film and do solid work: behind the surface drying of filming, oxygen gradually to the internal layer infiltration, impels the two key α of inner layer resin-H place formation superoxide from film coated surface, promptly is decomposed to form free radical and makes and film to the polymerization of depth curing cross-linked, reaches at last and does solid work.Along with doing solid work of filming, filming has also possessed certain rigidity and anti-solvent (as No. 200 gasoline) dissolved ability.For the evaluation of doing solid work with reference to the pressure filter paper method among the GB1728-79.
Experiment 1:

(1) hardness is pencil hardness, is as the criterion to scratch
(2) solvability of anti-No. 200 gasoline is meant on model and drips an amount of No. 200 gasoline, and films with the rolled paper wiping of exerting oneself, and films with galling, exposes ground and is as the criterion.
Experiment 2:
By the above method sample preparation plate, and put into 60 ℃ baking oven immediately, refer to touch dry method at 60 ℃ of surface dryings that whether judge by GB1728-79.
The result is as follows:
Table 9

Embodiment 8 brief summaries:
1. can find out from table 8 that Acetacetic acid alkyl ester cobalt chelates siccative is the same with traditional siccative to be had the water-base resin that contains dry vegetable oil and significantly urge the effect done.So blank sample does not contain the basic just crosslinking polymerization curing in a short time of siccative, does not therefore do solid work, and does not have hardness yet and can say, its anti-solvent solubility has great gap with the model that is added with siccative.
2. can learn also from table 8 that blank sample is similar to the model surface drying performance that has added siccative such as Acetacetic acid alkyl ester cobalt chelates.But in fact both have difference in essence.Do not add filming of siccative and crosslinking polymerization can't take place in a short time solidify, therefore if near or surpass under the softening temperature, blank sample is filmed and should be softened and can not surface drying.Added filming because for crosslinking polymerization solidifies surface drying of siccative, but near or above also surface drying under the softening temperature.We select 60 ℃ as probe temperature, and experimental result sees Table 9.As shown in Table 9, experimental result is consistent with anticipation, and this has illustrated that also Acetacetic acid alkyl ester cobalt chelates siccative of the present invention and traditional siccative have played same effect.
