Problems solved by technology

Chinese patent 02121246.5 reports multifunctional nano-zinc oxide suspoemulsion and its preparation method. In this method, nano-zinc oxide is modified. The preparation method is relatively complicated, and the content of nano-zinc oxide is also low.
Chinese patent 02159055.9 refers to surface-modified nano-zinc oxide dispersions and their preparation methods and uses, which are SiO 2 、Al 2 o 3 , Fe 2 o 3 It is deposited on the surface of nano-zinc oxide, and then mixed with silane coupling agent, water-soluble polymer and water. This dispersion is specially used to prepare UV-resistant textiles, and its application range is narrow
In addition, the nano-zinc oxide developed by U.S. Patent No. 5,914,101 has a solid content of 40-75%, but the zinc oxide has to undergo a complicated modification process before being dispersed, and the process is relatively cumbersome

Abstract

The invention belongs to the field of nano materials and particularly relates to nano zinc oxide slurry concentrate and a preparation method thereof. The slurry concentrate is made from 100 parts of nano zinc oxide with average particle size of primary particles being 50 nm and below, 5-10 parts of an organic carrion inhibitor, 0.1-0.3 part of an antirust pigment, 0.3-0.6 part of an aid, and 15-20 parts of an organic solvent; the components are proportionally weighed, the organic corrosion inhibitor, the antirust pigment and the aid are mixed well with the organic solvent, the nano zinc oxide powder is added gradually in non-stop running of a high-speed dispersing unit, and dispersing is continued for 5-30 min all the required nano zinc oxide powder is added, wherein the dispersing unit runs at 1500-2500 rpm; obtained nano zinc oxide slurry is ground for 1-10 min in a ball milling machine or grinding machine such that average particle size is 100 nm and below; the nano zinc oxide slurry concentrate is obtained. The slurry concentrate has good dispersion, good storage stability, high solid content, low viscosity, high compatibility and good antiseptic functionality.

Description

technical field [0001] The invention belongs to the field of nanometer materials, in particular to a nanometer zinc oxide concentrated slurry and a preparation method thereof. Background technique [0002] Nano zinc oxide is a functional material with a wide range of uses. It has optical, magnetic, thermal and sensitive properties that conventional bulk materials do not have. The product has high activity and has anti-infrared, ultraviolet and anti-virus and sterilization functions. It is mainly used in the following Field: (1) Rubber industry: The rubber industry is the largest user of zinc oxide. Nano-zinc oxide is used to manufacture high-speed and wear-resistant rubber products, such as aircraft tires and radial tires for high-end cars. Long service life and other functions not only change the apparent quality of rubber products, but also its dosage is only 30% to 50% of that of grade zinc oxide. (2) Coating: Adding nano-zinc oxide to the coating paint can not only shie...
