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

Abstract

The invention provides a preparation method for a nano additive. The preparation method is finished by the following steps: firstly, adding 5-10 parts of zinc oxide, 3-5 parts of titanium dioxide and 1-3 parts of a dispersant into a ball mill; grinding at the rotary speed of 400r / min-450r / min for 5-10 hours to obtain dry powder A; mixing the dry powder A according to the ratio of adding 5ml of ethanol into 1g of the dry powder; adding the mixture into the ball mill and continually grinding; adjusting the rotary speed to 400r / min-500r / min and carrying out ball milling or 4-6 hours to remove the ethanol; drying in vacuum to obtain dry powder B; adding 2-6 parts of montmorillonoid and 3-6 parts of vermiculite, and the dispersant into the ethanol; putting the mixture into an ultrasonic field, carrying out ultrasonic dispersion and peeling for 2-4 hours; after dispersing, removing the ethanol; and putting the product and the dry powder B into the ball mill to be ground for 2-4 hours at the speed of 400r / min-500r / min to obtain the compound nano additive.

Description

technical field [0001] The invention relates to the technical field of synthetic fiber processing aids, in particular to a preparation method of nanometer additives. Background technique [0002] Nylon is the trade name of polycaprolactam fiber in my country, and the foreign trade name is nylon. In 1938, German Schlack successfully researched polycaprolactam made of single caprolactam as raw material and heated polymerization, and applied for a patent. As early as 1955, DuPont of the United States applied for a patent for spinning nylon at a speed of 5,500 m / min. Nylon fiber has excellent performance, except for the corrosion resistance and mildew resistance common to all synthetic fibers, high wet strength, not afraid of insects, and moisture absorption. In addition to its low rate, its main feature is its high breaking strength. Except for aramid, it is almost the strongest fiber; it has excellent wear resistance and is the fiber with the best wear resistance among textile...
