specific Embodiment 1
[0030] A loaded Ag 6 Si 2 o 7 / g -C 3 N 4 A method for preparing a self-cleaning textile, comprising the steps of:
[0031] Step 1, calcining melamine to obtain g-C 3 N 4 . The specific process is: put melamine in a capped aluminum oxide crucible, heat it in an air-atmosphere muffle furnace, raise the temperature to 500°C at 5°C / min, calcinate for 3h, and cool naturally to room temperature to obtain g-C 3 N 4 .
[0032] Step 2, the fabric is pretreated, specifically:
[0033] 21), after mixing deionized water and absolute ethanol at a volume ratio of 1:1, solution A is obtained,
[0034] 22), adding 3-aminopropyltriethylsilane, the added mass of 3-aminopropyltriethylsilane is 3-6% of the mass of solution A, preferably 3%. At 40°C, shake for 50 minutes to obtain Sol B,
[0035] 23) Soak the washed and dried fabric in sol B in the dark for 100 minutes, take it out, press it, bake at 90°C for 20 minutes, at 155°C for 3 minutes, wash with deionized water, and dry at 50...
specific Embodiment 2
[0044] Step 1, calcining melamine to obtain g-C 3 N 4 . The specific process is: put melamine in a capped aluminum oxide crucible, heat it in an air atmosphere muffle furnace, raise the temperature to 550°C at 5°C / min, calcinate for 4h, and cool naturally to room temperature to obtain g-C 3 N 4 .
[0045] Step 2, the fabric is pretreated, specifically:
[0046] 21), after mixing deionized water and absolute ethanol at a volume ratio of 1:1, solution A is obtained,
[0047] 22), adding 3-aminopropyltriethylsilane, the added mass of 3-aminopropyltriethylsilane is 3-6% of the mass of solution A, preferably 4.5%. At 50°C, shake for 60 minutes to obtain Sol B,
[0048] 23) Soak the washed and dried fabric in sol B in the dark for 100-120 minutes, take it out, roll it, bake it at 95°C for 30 minutes, at 165°C for 4 minutes, wash it with deionized water, and dry it at 60°C.
[0049] Step 3, soaking the fabric obtained in step 2, specifically:
[0050] 31), a certain amount of...
specific Embodiment 3
[0057] Step 1, calcining melamine to obtain g-C 3 N 4 . The specific process is: put melamine in a capped aluminum oxide crucible, heat it in an air atmosphere muffle furnace, raise the temperature to 600°C at 5°C / min, calcinate for 5h, and cool naturally to room temperature to obtain g-C 3 N 4 .
[0058] Step 2, the fabric is pretreated, specifically:
[0059] 21), after mixing deionized water and absolute ethanol at a volume ratio of 1:1, solution A is obtained,
[0060] 22), adding 3-aminopropyltriethylsilane, the added mass of 3-aminopropyltriethylsilane is 3-6% of the mass of solution A, preferably 6%. At 60°C, shake for 70 minutes to obtain Sol B,
[0061] 23) Soak the washed and dried fabric in sol B in the dark for 100-120 minutes, take it out, roll it, bake it at 100°C for 40 minutes, at 175°C for 5 minutes, wash it with deionized water, and dry it at 70°C.
[0062] Step 3, soaking the fabric obtained in step 2, specifically:
[0063] 31), a certain amount of ...
