As shown in Table 1, the archaized tiles of the examples 1 to 3 have excellent anti-skid effect, fine and smooth texture of glaze surface, good antifouling property and high definition of ink-jet patterns; the raw material of the slip-resistant overglaze layer of comparative example 2 has low contents of kaolin and calcined kaolin, has insufficient aluminum content, has reduced stability and stain resistance, and is not favorable for color development of ink and blurred patterns.
1. Anti-skid testing
The antique bricks of examples 1-3 and comparative examples 1-2 were subjected to an anti-slip test using a European Standard DIN51130-2014 slope method anti-slip tester to determine the critical angle of dynamics by a tester walking on an engine oil-coated experimental sample with special shoes or walking with bare feet on a damp experimental sample. The results are shown in Table 2.
TABLE 2
The slope method antiskid detector in the antiskid test detects that the average critical angle is 26.7 degrees, the antiskid grade corresponding to the embodiment 1-3 is R10-11, and the archaized brick has a good antiskid effect; comparative example 1 had an anti-slip rating of R9 and poor anti-slip effect, and comparative example 2 had an anti-slip rating of R10.
The above embodiments are only preferred embodiments of the present invention, and the protection scope of the present invention is not limited thereby, and any insubstantial changes and substitutions made by those skilled in the art based on the present invention are within the protection scope of the present invention.
