Problems solved by technology

However, when the negative oxygen ion powder is used for leather filling, since the pH value of the leather at this time is around 6.5-7.5, it is easy to react with the negative oxygen ion powder, resulting in acidification of the leather surface, and the reunion of the negative oxygen ion powder, resulting in difficulty in penetration. , the production of negative oxygen ion leather is difficult to meet the health requirements when applied

preparation example Construction

[0057] The present invention provides a method for preparing the negative oxygen ion filler according to the present invention, which includes the step of mixing the components of the negative oxygen ion filler.

[0058] According to the preparation method of the present invention, it specifically comprises the following steps:

[0059] Step 1), dissolve the negative oxygen ion powder in water, and add an organic base to adjust the pH value to 5.0-7.0;

[0060] Step 2), in the solution obtained in step 1), add sulfite grease and penetrant;

[0061] Step 3), adding a thickener to the solution obtained in step 2); and adjusting the pH value to 6.0-8.0 with an organic base;

[0062] In step 4), an antiseptic is added to the solution obtained in step 3) to obtain a negative oxygen ion filler.

[0063] Preferably, in step 2), after the penetrating agent is added, the dispersion can be carried out by using a high-speed disperser, the dispersion time is 20-40 minutes, and the speed...

Embodiment 1

[0068] Disperse 15% of 4000 mesh negative oxygen ion powder and 25% of 12000 mesh negative oxygen ion powder in 45% water at high shear speed. After 2 minutes, add 1% organic base diethanolamine to adjust the pH value to 6.0. Then add 4% sulfited castor oil to the solution, and then add 7% penetrant containing sodium dodecylbenzenesulfonate (brand name: 8044EE), and continue high-speed dispersion for 30 minutes. Then add 2% acrylic thickener AX-60, stir for 15 minutes, add 0.5% organic base diethanolamine, stir to adjust the pH value to 7.0. Finally, 0.5% preservative (5-chloro-2-methyl-4-isothiazolin-3-one, brand: XL-2) was added and stirred for 5 minutes, and the mixture was uniformly discharged. The stirrer used is a stainless steel metal stirrer, the speed of high-speed dispersion is 800r / min, and the speed of stirring is 300r / min. Operate under normal temperature and normal pressure to obtain negative oxygen ion filler I. The negative oxygen ion filler I has a solid con...

Embodiment 2

[0070] Disperse 25% of 6000 mesh negative oxygen ion powder and 15% of 18000 mesh negative oxygen ion powder in 45% water at high shear speed. After 2 minutes, add 1.5% organic base triethanolamine to adjust the pH value of the mixture to 6.0. Then add 4% sulfited oleic acid to the solution, and then add 7% penetrating agent containing sodium dodecylbenzenesulfonate (brand: 8044EE), and continue high-speed dispersion for 30 minutes. Then add 1.5% silicon dioxide thickener A-200, stir for 20 minutes, add 0.5% organic base triethanolamine, stir for 5 minutes to adjust the pH value to 7.0, and finally add 0.5% composite preservative (brand: DL-T203 ) Stir for 5 minutes, discharge evenly. The stirrer used is a stainless steel metal stirrer, the high-speed dispersion speed is 800r / min, the stirring speed is 400r / min, and it is operated under normal temperature and pressure to obtain negative oxygen ion filler II. The negative oxygen ion filler II has a solid content of 45±1% and a...

Abstract

The invention relates to negative oxygen ion filler and a preparation method thereof. The negative oxygen ion filler comprises the following components of, by weight percentage, 30% to 50%, preferably35% to 45% of negative oxygen ion powder, 3% to 15%, preferably 4% to 10% of a penetrating agent, 3.0% to 6.0%, preferably 4.0% to 5.0% of sulfited oil, 0.5% to 2.5%, preferably 1.0% to 2.0% of organic alkali, 1.0% to 5.0%, preferably 1.5% to 30.% of a thickening agent and 0.1% to 1.0%, preferably 0.2% to 0.5% of a preservative agent. The negative oxygen ion filler provided by the invention can quickly permeate into leather fibers and can remarkably improve the leather filling effect and the sterilization and deodorization effect. The negative oxygen ion filler provided by the invention can be used for replacing the use of fillers in a traditional process, also obviously improves the release effect of negative oxygen ions, meets the filling requirements of the negative oxygen ions in leather production, achieves an excellent filling effect and also achieves sterilization and deodorization effects.

Description

technical field [0001] The invention relates to a negative oxygen ion filler and a preparation method thereof, belonging to the field of new materials. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the pursuit of leather products has become more and more prominent. Not only do they require perfection in design, style, and color, but they also put forward higher requirements in terms of comfort and functionality. For example, adhesives are used in the manufacturing process of leather shoes, which are prone to formaldehyde, toluene and other harmful organic volatiles when worn, causing great harm to consumers; sports shoes made of genuine leather are affected by the sweat of the feet. Very easy to produce bacteria and bad smell. [0003] Negative oxygen ion powder is a natural silicate mineral with a ring structure. It mainly contains boron, aluminum, sodium, iron, lithium, magnesium, calcium and other minerals. T...
