[0031] A method for preparing an outdoor high-hardness wear-resistant finish material, comprising the following steps in sequence:
[0032] S1: Prepare component A, including the following sub-steps in sequence:
[0033] 1) Add 10-20 parts of 1,6-hexamethylene diisocyanate and 10-20 parts of isophorone diisocyanate into the first dispersion container, and disperse for 30-40 minutes at the speed of 800-1000r / min;
[0034] 2) Adjust the speed of the disperser to 1200-1800r / min, add 1-3 parts of polyether, 3-8 parts of polyacrylic resin, 2-8 parts of p-tert-butylphenyl glycidyl ether while dispersing, and disperse for 20-30 minute;
[0035] 3) Adjust the speed of the disperser to 1000-1200r / min, add 0.1-0.6 parts of leveling agent and 0.3-0.5 parts of defoamer in turn while dispersing, and disperse for 18-22 minutes until mixed evenly;
[0036] S2: Prepare component B: Add 5-10 parts of hydroxyl-containing organic fluorine resin and 5-11 parts of hydroxyl-containing silicone re...

[0041] A method for preparing an outdoor high-hardness wear-resistant finish material, comprising the following steps in sequence:
[0042] S1: Prepare component A, including the following sub-steps in sequence:
[0043] 1) Add 15 parts of 1,6-hexamethylene diisocyanate and 15 parts of isophorone diisocyanate into the first dispersion container, and disperse for 35 minutes at a speed of 900r / min;
[0044] 2) Adjust the speed of the disperser to 1500r / min, add 2 parts of polyether, 5.5 parts of polyacrylic resin, and 5 parts of p-tert-butylphenyl glycidyl ether while dispersing, and disperse for 25 minutes;
[0045] 3) Adjust the speed of the disperser to 1100r / min, add 0.35 parts of leveling agent and 0.4 parts of defoamer in turn while dispersing, and disperse for 20 minutes until mixed evenly;
[0046] S2: Preparation of component B: add 8 parts of hydroxyl-containing organic fluorine resin and 8 parts of hydroxyl-containing silicone resin to the second dispersion vessel, a...

[0049] A method for preparing an outdoor high-hardness wear-resistant finish material, comprising the following steps in sequence:
[0050] S1: Prepare component A, including the following sub-steps in sequence:
[0051]1) Add 18 parts of 1,6-hexamethylene diisocyanate and 18 parts of isophorone diisocyanate into the first dispersion container, and disperse for 36 minutes at the speed of 950r / min;
[0052] 2) Adjust the speed of the disperser to 1600r / min, add 2.2 parts of polyether, 6 parts of polyacrylic resin, and 6 parts of p-tert-butylphenyl glycidyl ether while dispersing, and disperse for 26 minutes;
[0053] 3) Adjust the speed of the disperser to 1150r / min, add 0.35 parts of leveling agent and 0.35 parts of defoamer in sequence while dispersing, and disperse for 21 minutes until mixed evenly;
[0054] S2: Preparation of component B: add 8 parts of hydroxyl-containing organic fluorine resin and 9 parts of hydroxyl-containing silicone resin to the second dispersion con...
