Qi Jinhang toning, after hydrophobically modified celluloses, wetting agent and pregel are used in compounding, can be such that sand and color-mixed base paint is formed
Thick fluid advantageously forms independent color spot, avoids mill base dispersion and colour mixture；Coalescing agent and acrylic emulsion are conducive to
Color spot cured later film forming, color spot is clear, true to nature, has the verisimilitude of the lithotomes such as cladding marble, body coated on exterior wall
Existing building it is muddy as day at decorative effect.
The appraisal result of table 1 test specimen 1-15 and control sample 1-7
Test two performance tests
Test specimen: using the stone-like coating obtained in embodiment 1-15 as test specimen 1-15, by what is obtained in comparative example 1-7
Stone-like coating is used as control sample 1-7.
Test method: test sample is detected according to the method in JG/T24-2000 SAND SLURRY SYNTHETIC EMULSION ARCHITECTURAL COATINGS
The drying time of product 1-15 and control sample 1-7, water resistance, alkali resistance, adhesion strength and thermal storage stability.
Test result: the test result of test specimen 1-15 and control sample 1-7 are as shown in table 2.As shown in Table 2, it tests
Drying time, water resistance, alkali resistance, adhesion strength and the thermal storage stability of sample 1-15 meets the requirements of the standard, and right
Product 1-7 occurs being layered after 30 days, has precipitating in the same old way, and thermal storage stability does not meet standard requirements, illustrates that the present invention passes through
It chooses component and controls the proportion of each component, it is not stratified after long-time storage, do not sink so that stone-like coating storage stability is good
It forms sediment.
The test result of table 2 test specimen 1-15 and control sample 1-7
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
For those of ordinary skill, several improvements and modifications without departing from the principles of the present invention, these improvements and modifications are also answered
It is considered as protection scope of the present invention.
