The coatings obtained in example two and comparative example one were tested:
test 1: the flexibility of the paint films was tested according to GB/T1731-93 using a flexibility tester.
And (3) testing 2: according to GB/T1720-89, the adhesion force of a paint film is tested by a circle forming method
And (3) testing: the test was carried out by the rubber grinding wheel method according to the national standard GB/T1768-89, and the measurement was carried out using a wear meter model JM-3. The sample is cut into 10 x 10cm, fixed on the rotatable base of the abrasion instrument according to requirements, and the rubber grinding wheel is pressed well with the surface of the coating. When the load capacity is 1 multiplied by 10 Fahrenheit, the sample plate is rotated according to the specified rotating speed, and the grinding is stopped after 100 revolutions. And weighing the weight of the sample plate before and after abrasion by using an analytical balance, wherein the difference value is the abrasion loss.
And (4) testing: coating the paint on the surface of plastic, drying for later use, cutting the coated plastic film into samples slightly larger than 63mm × 63mm (the size of a small slide block) and 80mm × 200mm, fixing the samples on the small slide block and a sliding plate by using double-sided adhesive tapes respectively, measuring the friction coefficient of the contact surface of the plastic film by using a friction coefficient tester, measuring each sample for three times on average, and then averaging.
Flexibility/mm Adhesion/grade Abrasion loss per gram Coefficient of friction
Example two 2 2 0.0325 0.942
Comparative example 1 2 2 0.0742 0.627
From the test results, the coating material prepared in example two has substantially the same flexibility and adhesion as the coating material prepared in comparative example one, and it can be seen in the amount of abrasion that the amount of abrasion is greatly reduced after the nano-silica is modified, which indicates that the coating material prepared in example two has better durability because the nano-silica forms more stable chemical bonds with the whole coating material after being modified, and has better abrasion resistance than the nano-silica without modification. Of the coefficients of friction, the same example also had a better coefficient of friction than the comparative example one.
The core of the anti-slip coating is the anti-slip coating, the anti-slip coating is mainly produced by using acrylic resin and polyester polyol as main materials and using aliphatic isocyanate as a curing agent for reaction, wherein the key point is that modified nano-silica is added, aminated nano-silica can be subjected to ring-opening polymerization with caprolactone under the catalysis of phosphazene base so as to form a chemical bond with the nano-silica, and then the nano-silica is added into the curing polymerization of the acrylic resin, the polyester polyol and the aliphatic isocyanate so that the silica and the main materials are better combined, and the wear resistance and the anti-slip performance are improved.
