Embodiment 1

[0017] This embodiment relates to a preparation method of an additive for nylon spinning, the steps are as follows:

[0018] Step 1: First, add 6 parts of zinc oxide, 3 parts of titanium dioxide, and 1 part of polyvinylpyrrolidone into a ball mill at a speed of 150 rpm, and grind for 6 hours to obtain dry powder A.

[0019] Step 2: Mix dry powder A according to the ratio of 1 g of dry powder to 5 ml of ethanol, add to a ball mill, continue grinding, adjust the rotation speed to 200 rpm, ball mill for 5 hours, remove absolute ethanol, and dry in vacuum to obtain nano dry powder B.

[0020] Step 3: Add 4 parts of montmorillonite and 5 parts of vermiculite together with 1 part of sodium dodecylbenzenesulfonate to absolute ethanol. The content of dispersant and inorganic mineral salt in this mixture is 40-60%. Add this mixture Ultrasonic dispersion and stripping were carried out in an ultrasonic field for 3 hours. After dispersion, the ethanol was removed, and together with the dr...

Abstract

The invention provides a preparation method for a chinlon spinning additive. The preparation method comprises the following steps: step I, adding 3-6 parts of metal oxides and 1 part of polyvinylpyrrolidone into a ball mill, and grinding for 6 hours to obtain dry powder A; step II, mixing 1g of the dry powder A with 5ml of alcohol to obtain a mixture, adding the mixture into the ball mill, and performing ball-milling for 5 hours to obtain nano dry powder B; and step III, adding 4-8 parts of inorganic mineral salts and 1 part of sodium dodecyl benzene sulfonate into absolute ethyl alcohol to obtain a mixture, adding the mixture into ultrasonic fields to perform ultrasonic dispersing and stripping for 3h, removing alcohol, adding the alcohol-removed mixture and the dry powder B into the ball mill to perform ball-milling for 4h to obtain the compound nano additive. The nano additive prepared by adopting the method disclosed by the invention has good dispersion, and can be used for improving the stability of an oiling agent by being compounded with a normal oiling agent for use, and improving the smoothness and the antibacterial property of the oiling agent.

Description

technical field [0001] The invention relates to the technical field of additives in synthetic fiber processing technology, in particular to a preparation method of an additive for nylon spinning. Background technique [0002] Since the middle of the 1230s, the research and development of chemical fiber oils has started abroad. Since the development of foreign oils is completed by large companies, and the commercial value of the research results is very good, there are very few open oil formulations. Japan is the most active in the development and production of oil agents. The companies developing oil agents include Matsumoto, Teijin, Asahi Kasei, Kao, Henkel in Germany, and Taixiang Meihua in the United States. In the 1950s, in order to adapt to the common spinning process of nylon filaments, an oil agent based on mineral oil and adding emulsifiers and antistatic agents was developed. Since the mid-1960s, chemical fiber production has developed to a production process based...
