Aging Test老化试验

 

Weatherproof shingles were placed in 16 x8 cm, painted with two layers brush applied to the different samples of coatings, which were cured for 7 days indoors. Half of the specimen with foil cover and the other half are left exposed to the weather for a year. (Figure 1)

防水瓦尺寸16×8厘米,用刷涂2遍,在室内固化7天。试样借助箔覆盖,而另一半露天存放一年。 (图1



Cyclic Freeze/Thaw Test (ASTM C-672)循环冻/熔测试

Two layers of coating are applied on a high absorbent concrete surface.  Let stand 2 hours at room temperature between applications. Then, let dry for 48 hours at room temperature

The applied concrete surfaces are exposed to freeze-thaw cycles in the presence of deicing chemicals。

The test it is performed by placing ponding water on the surface of the coating, freezing overnight, then thawing with the aid of sodium chloride.

The results from the evaluation demonstrate the solvent borne coatings began to show damage to the coating and concrete at much earlier times。

两层涂层施加在一个高吸收性混凝土表面涂2遍,在涂第二遍前要在室温下静置2小时,然后,在室温下干燥48个小时。将混凝土表面进行冻融循环测试,用氯化钠做解冻剂。测试是通过将积水附着在涂层的表面冷冻过夜,然后用氯化钠的援助解冻。溶剂型涂料开始显现损坏该涂层和混凝土在更早次数。







The results from the evaluations over concrete demonstrate that a flexible, elastomeric water base acrylic can have excellent adhesion to concrete and masonry surfaces. Their flexibility leads to efficient bridging of substrate cracks, and allows some movement of the crack from temperature changes without damage to the film. The results shown here suggest that the flexibility also allows good resistance to the stresses imposed by freeze/thaw cycling. The more rigid solvent borne coatings evaluated in this study fail under these thermal stresses due to cracking of the film, and the resultant intrusion of water and salts.

以上的测试表明,水性丙烯酸弹性体在混凝土砖石表面具有优异的粘附性,它的柔韧性对基板的断裂有高效的桥接作用,适合温差变化大和裂缝的移动,而不会损坏涂料膜。此处示出的结果表明,灵活性也允许通过冷冻/解冻循环所施加的应力性好。在这些热应力由于涂料膜,以及水和盐所侵入裂解在这项研究中所评估的更刚性的溶剂型涂料失败

 

 

DIRT PICK-UP TEST沾污测试

 

Two layers of coating are applied on a high absorbent concrete surface.  Let stand 2 hours at room temperature between applications. Then, let dry for 24 hours at room temperature.

Cover half of the concrete surface with an aluminum foil and let stand 7 days at weather conditions。 After 7 days, uncovered the concrete surface and groove it with finely powered coal for 2 minutes。  Remove the coal and compare the degree of dirt pick-up between both halves。

两层涂层施加在一个高吸收性混凝土表面涂2遍,在涂第二遍前要在室温下静置2小时,然后,在室温下干燥24个小时。 用铝箔纸覆盖一半的混凝土表面,然后置于室外7天。7天后,揭开混凝土表面和凹槽用细煤粉覆盖2分钟。除去煤后比较两半之间积垢的程度。

Elongation at break test were measured according

断裂伸长率测试是根据  ASTM D-2370

 

Were prepared one layer the coatings the 3,5 mils thickness.

The coating specimens are left dry for 7 days at room temperature and placed in 24 hours weather.制备一层涂层为3,5密耳厚度。在室温下该涂层试样干7天,并放置在室外24小时。
