Embodiment 1
[0020] A method for modifying toughened marble back-adhered fiber mesh cloth, the specific steps are:
[0021] S1: Mix pure acrylic resin and water evenly in a ratio of 2:1, set aside.
[0022] S2: In the form of high-speed mechanical dispersion of nano-silica, fully and evenly disperse into the resin solution obtained in S1, and set aside.
[0023] S3: Stir and mix the silane coupling agent γ-glycidyloxypropyltrimethylsilane and the alcohol-water mixture (methanol accounts for 75%) evenly, the mixing mass ratio is 2:100, and prepare it as a surface modifier for use.
[0024] S4: Immerse the glass fiber mesh cloth in the surface modifier obtained in S3. After the wetting is complete, take it out and dry it at 50°C, then immerse it in the surface modifier again, repeat once, and set aside.
[0025] S5: Immerse the modified glass fiber mesh cloth obtained in S4 into the pure acrylic resin solution containing nano-silica obtained in S2, take it out and dry it after it is complet...
Embodiment 2
[0027] A method for modifying toughened marble back-adhered fiber mesh cloth, the specific steps are:
[0028] S1: Mix pure acrylic resin and water evenly in a ratio of 3:1, set aside.
[0029] S2: In the form of high-speed mechanical dispersion of nano-silica, fully and evenly disperse into the resin solution obtained in S1, and set aside.
[0030] S3: Stir and mix the silane coupling agent γ-(methacryloyloxy)propyltrimethoxysilane and alcohol-water mixture (methanol accounts for 80%) evenly, and the mixing mass ratio is 3:100 to prepare a surface modifier spare.
[0031] S4: Immerse the glass fiber mesh cloth in the surface modifier obtained in S3. After the wetting is complete, take it out and dry it at a temperature of 55°C. Immerse it in the surface modifier again, repeat twice, and set aside.
[0032] S5: Immerse the modified glass fiber mesh cloth obtained in S4 into the pure acrylic resin solution containing nano-silica obtained in S2, take it out and dry it after it...
Embodiment 3
[0034] A method for modifying toughened marble back-adhered fiber mesh cloth, the specific steps are:
[0035] S1: Mix silicone acrylic resin and water evenly in a ratio of 2:1, set aside.
[0036] S2: In the form of high-speed mechanical dispersion of nano-silica, fully and evenly disperse into the resin solution obtained in S1, and set aside.
[0037] S3: Stir and mix the silane coupling agent γ-mercaptopropyltriethoxysilane and the alcohol-water mixture (methanol accounts for 82%) evenly, the mixing mass ratio is 3:100, and prepare it as a surface modifier for use.
[0038] S4: Immerse the glass fiber mesh cloth in the surface modifier obtained in S3. After the wetting is complete, take it out and dry it at 60°C, then immerse it in the surface modifier again, repeat 2 times, and set aside.
[0039] S5: Immerse the modified glass fiber mesh cloth obtained in S4 into the silicon acrylic resin solution containing nano-silica obtained in S2, take it out and dry it after it is ...
