gloss test method: referring to a GB/T1743-89 paint film glossiness measurement test, coating a little gloss oil emulsion on 128g of coated paper selected according to GB/T450, drying to form a film, and measuring the glossiness of the dried film layer by using a 75-degree angle gloss meter;

scratch resistance test method: according to ISO 12137-2:1997 standard, coating gloss oil on a 150 x 70mm hard aluminum plate meeting GB9271 standard, drying for at least more than 16 hours under the conditions of temperature (23 +/-2) DEG C and relative humidity (50 +/-5)%, clamping the test plate on a sliding plate, gradually increasing the weight, and measuring the minimum gram weight of the film penetrated by the scriber;

the abrasion resistance was tested according to two methods: 1. according to the GB/T1786-2006 standard test, a dried sample is placed on a stripping friction surface coefficient instrument, a fixed speed is adopted as an instrument calibration speed 1, and a friction experiment with 10 times of friction is adopted to test the gloss change of the sample before and after the friction, the gloss abrasion resistance of the gloss oil is represented by gloss abrasion loss, the lower the gloss abrasion loss is, the better the abrasion resistance of the aqueous gloss oil is, and the worse the gloss abrasion loss is, the gloss abrasion loss is = (gloss-gloss after friction)/gloss; 2. referring to QB/T5345-2018 standard test, the rubbing times are recorded when rubbing is started to fade under 4 pounds of load by using a YMTS ink abrasion resistance tester.
