[0038] The second embodiment of the present invention provides the preparation method of negative oxygen ion composition, comprises the following steps:
[0039]reacting water, negative oxygen ion powder and sodium anthraquinone sulfonate at 70-90°C for 6-10 h to obtain an anthraquinone sulfonic acid negative ion complex; Film resin, dispersant and pigment paste, stirred at 25-40°C for 3-6 h. The purpose of the first step is to provide sufficient temperature and time to fully coordinate the sodium anthraquinone sulfonate and the negative oxygen ion powder to form an anthraquinone sulfonate negative oxygen ion complex to ensure that the energy absorbed by the sodium anthraquinone sulfonate can be transferred Give the rare earth elements in the negative oxygen ion powder, so that the negative oxygen ion material can emit stronger energy, thereby generating more negative oxygen ions; the purpose of the second step is to enhance The viscosity of the composition increases the disp...
Embodiment 1
[0054] The preparation of negative oxygen ion composition:
[0055] (1) In parts by weight, 5 parts of water, 0.9 parts of negative oxygen ion powder, and 0.35 parts of anthraquinone-1-sodium sulfonate were placed in a reactor, and stirred at a temperature of 80°C for 6 h to obtain anthraquinone-1 - sulfonic acid negative oxygen ion complex;
[0056] (2) To the anthraquinone-1-sulfonic acid anion complex in step (1), add 30 parts of Dawelik RA1260 medium-soft acrylic resin, 0.2 parts of dodecyl betaine and 10 parts of H151 high-physical pigment paste, Stirring at a temperature of 32°C for 3 h, a low-cost, high-efficiency negative oxygen ion composition was obtained.
[0057] Application of negative oxygen ion composition in leather finishing:
[0058] The leather base obtained by the conventional process is dampened, left standing for 6.5 h, the humidity is controlled to be 14%, the leather is ground, and then roll coating is carried out with a negative oxygen ion compositio...
Embodiment 2
[0061] The preparation of negative oxygen ion composition:
[0062] (1) In parts by weight, put 7.5 parts of water, 0.3 parts of negative oxygen ion powder, and 0.5 parts of sodium anthraquinone-2-sulfonate in a reactor, and stir at a temperature of 70°C for 10 h to obtain anthraquinone-2 - sulfonic acid negative oxygen ion complex;
[0063] (2) Add 20 parts of Daweiliyou RU2350 aliphatic polyurethane resin, 0.6 parts of octadecyltrimethylammonium chloride and 6 parts of PP to the anthraquinone-2-sulfonic acid anion complex in step (1) - The 20-112 microparticle pigment paste is placed in a reactor and stirred at a temperature of 25°C for 4.5 hours to obtain a low-cost, high-efficiency negative oxygen ion composition.
[0064] Application of negative oxygen ion composition in leather finishing:
[0065] The leather base obtained by the conventional process is dampened, left standing for 5 h, controlled humidity is 16%, ground, and then roll-coated with a negative oxygen ion ...
