The color-complementing paste of the embodiment and the existing color-complementing paste are subjected to covering power detection, and the detection method is an eye detection method, and specifically comprises the following steps: coating the white substrate glass plate with the color-compensating paste until the white color can not be sensed by human eyes, and weighing the coating film of the glass plate to obtain the weight, namely the covering power of the color-compensating paste; the color paste of this example and the existing color paste were each coated on 10 glass plates, weighed, and averaged.
The detection result is as follows: the dosage of the color-supplementing paste per square meter in the embodiment is 0.8 of the dosage of the existing color-supplementing paste per square meter. According to the detection result, the color-supplementing paste of the embodiment has higher covering power.
The color-complementing paste of the embodiment and the existing color-complementing paste are subjected to surface color rubbing fastness detection, wherein the detection method is a leather surface color rubbing fastness test method QB-T/1327-: the basic principle is that the degree of color transfer of a part of the leather surface to the lining cloth is achieved in the process of reciprocating friction of the lining cloth on the leather surface under the action of specified pressure, and the grade is judged in a visual mode by using a gray sample card. The detection of the color rubbing fastness of the surface is divided into dry rubbing and wet rubbing, the basic principle and the method are the same, and the difference is that the lining cloth used for the wet rubbing test needs to be dipped with equal amount of distilled water. The test method is to take the same leather and cut 10 leather blocks with the length of 100mm and the width of 30mm into 5 groups for testing. 5 pieces of the color-complementing paste of the present embodiment were uniformly applied to the test group, and another 5 pieces of the color-complementing paste were uniformly applied to the test group to serve as a control group. Adjusting a reciprocating screw rod of a leather surface color rubbing fastness tester to a reciprocating speed of 30 +/-2 times/min, wrapping lining cloth made of white cloth on a rubbing head, placing a sample on a base of the tester, starting the tester to reciprocate 25 times, stopping the tester, taking down the lining cloth, comparing the color depth transferred from the leather surface to the lining cloth with a standard gray sample card under the same natural light source of a north window, and judging the grade in a visual mode.
The detection result is as follows: in five groups of tests, the dry rub grades of the experimental groups in the embodiment are respectively 4-5, 4-5 and 4-5, the average value is 4-5, and the wet rub grades are respectively: 4. 4, 4 with an average value of 4; in five groups of detection, the dry wiping grades of the control group are respectively 4, the average value of 4 is 4, and the wet wiping grades are respectively: 3-4, 3-4 average value is 3-4. It is concluded that the color paste of the present embodiment has higher surface color rubbing fastness than the existing color paste grades, and has more excellent color fastness.
