The gloss oils obtained in the above examples and comparative examples were subjected to film formation test, and the results of the performance test are shown in table 1 below.
TABLE 1 results of Performance test of the oil films obtained in examples and comparative examples
According to the formula, the elasticity of the gloss oil film can be increased by adding the acrylic acid modified polyurethane, the wear-resistant auxiliary agent migrates to the surface of the gloss oil film in the film forming process of the gloss oil film, a very thin organic silicon layer is formed on the surface of the gloss oil film, when the gloss oil film is subjected to external force, the organic silicon layer of the surface layer is harder to resist external force friction, the lower resin layer has elasticity, part of force can be stored, the stored force is released after the external force disappears, and the wear-resistant performance of the gloss oil can be greatly improved under the synergistic effect of the acrylic acid modified polyurethane and the wear-resistant auxiliary agent.
In the process of forming the gloss oil film, the wax emulsion and the wear-resistant auxiliary agent float on the surface of the gloss oil film, and the wear-resistant auxiliary agent has extremely strong hydrophobicity besides excellent wear resistance. The wax emulsion 2 and the wear-resistant auxiliary agent are extremely low in surface energy, water drops cannot spread on the surface of the wax emulsion 2 and the wear-resistant auxiliary agent to generate water extraction performance with 'lotus leaf effect', the wax emulsion 1 is modified paraffin emulsion without an emulsifying agent, no polar functional group exists, the wax emulsion 2 and the wear-resistant auxiliary agent repel water, the wax emulsion 1 does not absorb water, the wax emulsion 1, the wax emulsion 2 and the wear-resistant auxiliary agent float to the surface of the varnish to form a compact isolation layer, the bonding force is weak, the bonding performance during contact is reduced, and 3 synergistic effects are achieved, so that the water diffusion is prevented, the water resistance effect is achieved, and the anti-sticking effect is also achieved.
It should be understood that the foregoing examples of the present invention are provided merely for clearly illustrating the present invention and are not intended to limit the embodiments of the present invention, and that various other changes and modifications may be made therein by one skilled in the art without departing from the spirit and scope of the present invention as defined by the appended claims.
