Embodiment 1
[0014] The present embodiment provides a kind of preparation method of nano-additive. The preparation steps of described nano-additive are as follows:
[0015] Step 1: First, add 5 parts of zinc oxide, 3 parts of titanium dioxide, and 0.5 parts of dispersant into the ball mill at a speed of 350 rpm, and grind for 8 hours to obtain dry powder A
[0016] Step 2: Mix dry powder A according to the ratio of 1g dry powder to 5ml ethanol, add it to a ball mill, continue grinding, adjust the speed to 480 rpm, ball mill for 5 hours, remove absolute ethanol, and vacuum dry to obtain nano dry powder B
[0017] Step 3: Add 2 parts of montmorillonite and 3 parts of vermiculite together with 0.5 parts of dispersant to absolute ethanol. The content of inorganic mineral salts in this mixture is 40-60%. Put this mixture into an ultrasonic field for ultrasonic dispersion and stripping for 3 hours , after dispersing, remove the ethanol, together with the dry powder B, continue to add to the ball...
Embodiment 2
[0019] The present embodiment provides a kind of preparation method of nano-additive. The preparation steps of described nano-additive are as follows:
[0020] Step 1: First, add 10 parts of zinc oxide, 5 parts of titanium dioxide, and 1.5 parts of dispersant into the ball mill at a speed of 350 rpm, and grind for 7 hours to obtain dry powder A
[0021] Step 2: Mix dry powder A according to the ratio of 1g dry powder to 5ml ethanol, add it to a ball mill, continue grinding, adjust the speed to 480 rpm, ball mill for 5 hours, remove absolute ethanol, and vacuum dry to obtain nano dry powder B
[0022] Step 3: Add 6 parts of montmorillonite and 6 parts of vermiculite together with 1.5 parts of dispersant to absolute ethanol. The content of inorganic mineral salt in this mixture is 40-60%. Put this mixture into an ultrasonic field for ultrasonic dispersion and stripping 2.5 h, after dispersing, remove the ethanol, and continue to add the dry powder B into a ball mill at 600 rpm f...
Embodiment 3
[0024] The present embodiment provides a kind of preparation method of nano-additive. The preparation steps of described nano-additive are as follows:
[0025] Step 1: First, add 7 parts of zinc oxide, 4 parts of titanium dioxide, and 1.5 parts of dispersant into the ball mill at a speed of 350 rpm, and grind for 6 hours to obtain dry powder A
[0026] Step 2: Mix dry powder A according to the ratio of 1g of dry powder to 5ml of ethanol, add it to a ball mill, continue grinding, adjust the speed to 450 rpm, ball mill for 5.5 hours, remove absolute ethanol, and vacuum dry to obtain nano dry powder B
[0027] Step 3: Add 4 parts of montmorillonite and 2 parts of vermiculite together with 1.5 parts of dispersant to absolute ethanol. The content of inorganic mineral salt in this mixture is 40-60%. Put this mixture into an ultrasonic field for ultrasonic dispersion and stripping for 3 hours , after dispersion, remove ethanol, together with dry powder B, continue to add to the ball ...
