Can measure the coating decoration performance of a series of coating materials by the method for the present invention, such as (but being not limited to) is selected from the coating material of lower group: inner-outer wall emulsion paint, wood lacquer, paint, putty, waterproof paint, mortar etc.
In the present invention, a kind of preferred testing method is as follows:
Testing method:
1, test panel need to keep surface clean, smooth, and adjustment sensor is to point of contact;
2, start data collecting system, testing sensor is corrected and makes zero, and setting data transfer rate;

Result judges:
A value is more big, shows that the construction feel of sample is more poor, and construction is firmly big, and construction is painstaking, and the application property of this sample is also more poor.
In former Chinese patent 201110039178.3 method, adopt operating efficiency and construction size firmly, as judging basis; For same workmen, data have certain reference significance, but for different workmens, the reference significance of data is little. Because different constructions is artificial, trick speed of working inherently varies with each individual, and skilled degree of constructing also varies with each individual, the workman that handicraft is good, even if the sample of more difficult construction, also can be coated with very soon and brush; And the workman that handicraft is poor or natural disposition is slow, even if holding easy working sample, also being spent the relatively long time to be coated with and brushing, cause the operating efficiency calculated very low; , also there is same problem in construction numerical value firmly, has the born power of people big, no matter brush what product, all by very big power, and can have that the born power of people is little or Construction Skills is grasped, no matter how construct, power all little.
In order to avoid the problems referred to above, the impact of above-mentioned factor must be got rid of, therefore, in test process, every time before test, increase the brushing data test of clear water, during calculating, by average exerting oneself during brushing sample, divided by average exerting oneself during brushing clear water, the numerical value obtained, namely as the basis for estimation of construction feel; After adopting the method, can effectively avoid the error that different human factor causes, the manual feel numerical value calculated, no matter be same personnel or different personnel, all possess certain dependency and reference significance.
Test result shows, for specific product, A value has certain scope, and such as, the A value that the test of general interiro wall latex paint obtains is roughly at about 1.2-1.5, and waterproof paint can reach 2.0-2.5. This shows that the method for the application can show the character of coating material itself well.
The major advantage of the present invention comprises:
(1) the inventive method eliminates the impact of the uncertain factor such as test condition and tester to greatest extent, and test data repeatability is good, it is possible to effectively react coating decoration complexity.
(2) testing method of the present invention is simple, and can be applied to most of coating material, applied widely, is suitable as general coating material judgement criteria.
Below in conjunction with specific embodiment, set forth the present invention further. Limit the scope of the invention it will be understood that these embodiments are only not used in for illustration of the present invention. The experimental technique of unreceipted concrete condition in the following example, usually conveniently condition, or according to the condition that manufacturer advises. Unless otherwise indicated, otherwise per-cent and part number calculate by weight.
The coating performance test of embodiment 1 interiro wall latex paint
1, set 9 data collection points, and it is evenly distributed on the test panel of 2 square metres of sizes, to guarantee to test the stressing conditions of different sites;
2, by the transfer speed of data collection point for being set as, and confirm that data acquisition unit has contacted with test panel and normal operation 100 time/second;
3, turn-on data acquisition system, starts construction simulation action on test panel, and whether test macro running is normal, debugs the record of test curve and data, it is ensured that record accurate simultaneously;
4, on test panel, it may also be useful to clear water carries out simulation brushing, and the data of 9 points are gathered and analyze by setting data acquisition system respectively;
5, interiro wall latex paint to be measured is diluted in proportion and stir evenly;
6, start to carry out roller coating construction on test panel surface;
7, the data of 9 points are gathered and analyze by setting data acquisition system respectively;
8, data process&analysis:
By first, second 2 different workmens brush respectively A B C tri-samples, test data record is as follows:
According to original appraisal procedure, the size of operating efficiency (construction used time) or the average force value of construction passes judgment on the quality of sample construction feel, then according to above data, during workmen's first brushing A sample, firmly it is less than workmen's second, and operating efficiency (construction used time) is greater than workmen's second, according to judge rule, firmly little or the used time is few, belong to construction good hand touch, and the situation that two data are contrary has occurred in reality, cannot pass judgment on; If assessing for different products, similar problem can be run into equally. Because the construction of different personnel cannot skillfully be spent by operating efficiency (construction used time) carries out quantitative evaluation, and easily it is subject to the impact of the factors such as some such as natural disposition trick speeds, therefore, the operating efficiency data refer that actual test obtains is worth also little, easily cause misleading on the contrary, in the method, do not adopt these data as judging basis.
The condition of construction data record of the inventive method is as follows. Before construction, each workmen increases brushing clear water, as reference, calculates construction feel parameter A, and calculation result is as follows:
Can see from above-mentioned calculation result, for 3 different samples, 2 different workmens, although construction firmly has obvious difference, also there is notable difference the construction used time, but the construction feel parameter A calculated very close, it is possible to effectively get rid of the impact of different workmen, thus characterize the performance of coating material itself comparatively accurately.
After improving test and judgment method, considerably reducing the impact of human factor, judgment method is also more simple and clear.
The coating performance test of the different coating of embodiment 2
Adopt method as identical in embodiment 1, test different coating materials respectively, such as emulsion paint, waterproof mortar, waterproof paint, oil-base paint etc., also the workmen of different skilled degree is allowed to test respectively, the construction feel parameter A calculated, for same product, is substantially stable, illustrate that this testing method can react the character of coating itself, there is using value.
Visible, utilize the method and device can realize the fast and convenient quality judging decorations coating material (such as coating, mortar, putty etc.) construction feel, and detected result is not by the impact of the factors such as workmen's individual factor, execution conditions, thus the reference data that can quantize is provided, it is achieved that the original intention of the present invention. And the method is not by the restriction of coating material type, it is possible to be applied to multiple coating material.
The all documents mentioned in the present invention are quoted as a reference all in this application, are just quoted separately as a reference as each section of document. In addition it will be understood that after the above-mentioned teachings having read the present invention, the present invention can be made various changes or modifications by those skilled in the art, these equivalent form of values fall within the application's appended claims limited range equally.
