Hardness test: with 3H pencil (Chinese board or Mitsubishi's board), pen core is whittled into cylindrical and after polishing on 400 order sand paper, be contained on special pencil hardness tester that (load be applied on nib is 750g, the angle of pencil and horizontal plane is 45 °), about 1cm is pushed at the substrate surface that embodiment 1-4 is obtained long with the speed of 1mm/s, draw 5 altogether, then with eraser by pencil trace wiped clean.Through aforesaid operations, the present embodiment anti-soil substrate surface does not occur breaking and exposes base material, and the anti-soil wear-resistant paint Rockwell hardness that therefore prepared by the present embodiment reaches 3H.
Wearability test: be stained with the cleaning agent solution of 5% on scouring pad, heavy burden 20N, the substrate surface wear resistant instrument obtained at embodiment 1-4 is with the speed friction 10cm of per minute 10 times, totally 100 times (one is once back and forth), if coat side does not expose base material phenomenon, wear resistance is good.Through aforesaid operations, the present embodiment anti-soil substrate surface does not occur breaking and exposes base material, and therefore the anti-soil wear-resistant paint wear resistance prepared of the present embodiment is good.
Solvent resistance test: weigh 500 gram forces by the face bear that cotton Fen Do picks alcohol, normal hexane (two solvents can not at same position) is soaked in the base material bight 10mm that embodiment 1-4 obtains and put on coatingsurface and repeatedly to rub 30 times/30S, if dissolution phenomena does not occur coat side, then solvent resistance is good.Through aforesaid operations, there is not dissolution phenomena in the present embodiment anti-soil substrate surface, and therefore the anti-soil wear-resistant paint solvent resistance prepared of the present embodiment is good.
Sticking power is tested: (mark the wide lattice of 10 horizontal 10 vertical clearance 1mm (cut deeply and base material) with cross-cut tester at the obtained substrate surface of embodiment 1-4, removing surface debris, indentation is covered with 3M (250) adhesive plaster, refer to that abdomen rubs (can not have bubble) back and forth on adhesive tape with mother, with become with test surfaces an angle of 90 degrees degree rapidly vertical by adhesive tape from surperficial pull-up, same position tests 3 times, if each test lattice comes off, area is no more than 1/3 of lattice area, and only have at most non-conterminous 3 lattices area that comes off to be no more than 1/3 of lattice area, then sticking power is good.Through aforesaid operations, there is not obscission in the present embodiment anti-soil substrate surface, and therefore the anti-soil wear-resistant paint sticking power of base material that obtains of embodiment 1-4 is good.
Last it is noted that above each embodiment is only in order to illustrate technical scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
