Embodiment 1-18 and comparative example the 1-6 water-in-water multicolor coating provided are tested for the property, as a result such as 1 institute of table
Show:
Wherein, 1. color grain intensity ratings are 1-5 points, specific standards of grading are as follows: 5 points of expression color grain intensity are fine, normally apply
Working hour will not be destroyed, and 4 points of expression color grain intensity are preferable, and color grain has minimal amount to be destroyed and becomes smaller when normal construction, but basic
Do not influence form and aspect, 3 points of expression color grain intensity are general, when normal construction color grain have it is a certain amount of be destroyed, color grain becomes smaller more serious, table
Now small for template overall color point, 2 points of expression color grain intensity are poor, and color grain is largely destroyed when normal construction, and color grain becomes smaller seriously,
Color grain part colours mix, and show as that template form and aspect are uneven, and 1 point of expression intensity is very poor.2. colorful water-water coating lacquer
The test method of the roughness of film is to take a small amount of water-in-water multicolor coating, and the water of equivalent is added, abundant using oscillator after tinning
It after shaking 3-5min, is filtered using the sieve of different meshes, record can just be by the mixture mistake of all paint samples and water
Complete sieve is filtered, and tests and the mixture of all paint samples and water can just be filtered complete sieve particle size, will be surveyed
Try sieve particle size is denoted as the roughness of hygrometric state paint sample.
3. the sand sense of paint film is characterized with coefficient of friction, the test method of paint film sand sense are as follows: take the water-water of equivalent more
Color coating material is carried out criticizing on the smooth no asbestos fibre cement plate of same area and be scraped, and after paint film is dry, is surveyed using coefficient of friction
Determine instrument measurement dynamic friction coefficient μ value, μ value is bigger, and it is better to represent sand sense.4. viscosity: being measured using stormer viscosity meter；
5. thixotroping value use rotary viscosity design determining, test method are as follows: will paint sample No. 6 rotor (6#) revolving speeds be 6rmp and
Viscosity number when 60rmp, then measure viscosity number ratio 6#60rmp with 6#6rmp and measure viscosity number to get to thixotroping value.
6. the color grain form of color grain after roller application: being divided into 1-5 points: 5 points representatives according to the integrated degree of color spot after construction
Color grain is complete after construction；Color grain minimal amount destroys after 4 points of representative constructions, does not influence form and aspect；Color grain is a certain amount of after 3 points of representative constructions
It destroys, color grain becomes smaller seriously, and it is small to show as template overall color point；Color grain is largely destroyed after 2 points of representative constructions, and color grain becomes smaller sternly
Weight, color grain part colours mix, and it is uneven to show as template form and aspect；Color grain is all destroyed after 1 point of representative construction,
Color grain mixes, and loses original form and aspect completely.
7. the uniform distribution of forces of color grain after roller application: the degree of being evenly distributed of color grain is commented after according to construction
Point, it is divided into 1-4 points, 4 points represent color grain and are evenly distributed, and form and aspect uniformly achieve the effect that imitate stone material；3 points represent color grain distribution compared with
Uniformly, the place for having a small amount of color grain on the low side, but whole form and aspect are not influenced；2 points represent color grain and are distributed more uneven, whole top
Divide local color spot more, part color spot is less, influences form and aspect；1 point represents that color grain distribution is very uneven, and color dot is with applying on the whole
Work tool is dragged away, and color spot is caused to be accumulated.
1 water-water coating property tables of data of table
Note: in upper table --- it is poor to represent effect of decorative patterns, is unable to reach water-water coating imitation stone effect.
As it can be seen from table 1 the comparison of embodiment 1-18 and comparative example 2-6 can be seen that embodiment 1-18 by specific
The color grain of quality proportioning is mutually cooperateed with white sand, aqueous acrylic emulsion and non-association type alkali swollen thickener, obtained water packet
The thixotroping value of water paint is above 5.5, is more likely to thixotropic system, can construct using roller coating or by the way of batch scraping.
The water-in-water multicolor coating that comparative example 1 provides, can not since its color grain content is too low although also forming thixotropic system
Reach the effect of decorative patterns of imitation stone.
It can be seen that from the comparison of embodiment 1-10 and embodiment 11-12 when preparing color grain, base paint and the first protection
The mass ratio of glue is (1-6): when (1-3), the intensity of the color grain being prepared is high, more preferably with the synergistic effect of continuous phase, makes
It obtains and keeps complete when being more conducive to construct while the colorful painting coating of water-water forms high thixotroping value thixotropic system.
It can be seen that from the comparison of embodiment 1-10 and embodiment 13 by using the acrylic emulsion containing associative groups and be
The raw material of base paint can effectively improve the intensity of color grain, more conducively keep complete in the construction process.
It can be seen that from the comparison of embodiment 1-10 and embodiment 14 fine by using high molecular weight hydrophobically modified hydroxyethyl
It ties up plain ether and replaces the raw material painted based on hydroxyethyl ether cellulose, the intensity for the color grain being prepared is higher, is more conducively applying
It is kept during work complete.
From the comparison of embodiment 1-10 and embodiment 15-16 as can be seen that base paint passes through the acrylic acid containing associative groups
Lotion 25-30wt%, the second protection sol solution 8-10wt%, high molecular weight hydrophobically modified hydroxyethyl cellulose ether 1-1.5wt%
It is mutually cooperateed with water 50-60wt%, the performance for the color grain being prepared is more excellent, and more complete after construction, dispersion is more evenly.
From the comparison of embodiment 1-10 and embodiment 17-18 as can be seen that the partial size of the white sand used in the continuous phase for
When 80-120 mesh, more evenly, decorative pattern imitation stone effect is more for color grain distribution in the paint film for the water-in-water multicolor coating being prepared
It is true to nature.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
