specific Embodiment approach 1

[0025] Specific embodiment one: present embodiment a kind of negative ion powder for decoration material, it is by mass parts by the tourmaline powder of 80 parts~90 parts of porous chitosan film coating and growth nano-silver, 5 parts~10 parts of opal powder and It is made by mixing 5-10 parts of neodymium oxide.

[0026] The beneficial effects of this embodiment are:

[0027] Under the synergistic effect of chitosan and nano-silver in this embodiment, the antibacterial properties of negative ion powder are improved, and by first coating the porous chitosan film, and then carrying out the growth of nano-silver, due to the polarity and complexation of the tourmaline surface Under the combined action of adsorption, it is very easy to adsorb various valence ions. Therefore, platinum chloride enters through the pores of chitosan film, forms growth points on the surface of tourmaline, and then grows nano-silver. The concentration of the solution and the growth time make the tourm...

specific Embodiment approach 2

[0028] Specific embodiment two: present embodiment a kind of preparation method of decoration material negative ion powder, it is finished according to the following steps:

[0029] 1. Chitosan coating of tourmaline powder:

[0030] Prepare a chitosan acid solution with a concentration of 5-15g / L, then immerse the mechanically treated tourmaline powder in the chitosan acid solution with a concentration of 5-15g / L, and stir at a stirring speed of 500r / min-800r Under the condition of 1 / min, stir for 5min to 10min, then stop stirring, let stand at a temperature of 40°C to 60°C, finally centrifuge, wash and dry to obtain tourmaline powder coated with porous chitosan film;

[0031] The thickness of the porous chitosan film in the tourmaline powder coated with the porous chitosan film is 10nm~500nm;

[0032] Second, the growth of nano-silver:

[0033] Use silver nitrate, polyvinylpyrrolidone and ethylene glycol to prepare a silver salt solution, soak the tourmaline powder coated w...

specific Embodiment approach 3

[0037] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that: the particle size of the mechanically treated tourmaline powder in step 1 is less than 2 μm. Others are the same as in the first or second embodiment.

Abstract

The invention discloses negative ion powder for a decoration material and a preparation method and application thereof, relates to negative ion powder and a preparation method and application thereof,and aims to solve the problems of limited negative ion generation capacity and no antibacterial property of negative ion powder in the existing application process. The negative ion powder for the decoration material is formed by mixing tourmaline powder, opal powder and neodymium oxide, wherein the tourmaline powder is coated with a porous chitosan film and nano-silver grows on the tourmaline powder. The method comprises the following steps: 1, coating tourmaline powder with chitosan; 2, growth of nano-silver; 3, mixing. The application is as follows: the negative ion powder for the decoration material is used for preparing the environment-friendly latex paint.

Description

technical field [0001] The present invention relates to negative ion powder and its preparation method and application. Background technique [0002] Negative ion powder is a powder that can generate air negative ions, mainly including tourmaline powder and rare earth elements, etc. The ratio of rare earth elements is much higher than that of tourmaline powder, and rare earths account for more than 60%. Among them, tourmaline is a borosilicate mineral with complex structure and composition. It has piezoelectricity and pyroelectricity, and can release far infrared rays and negative ions and other unique functions. [0003] Due to the large specific surface area and high specific surface energy of tourmaline powder particles, it is easy to agglomerate in the process of preparation and processing, which makes the dispersion of tourmaline uneven in the application process, which will affect the ability of tourmaline powder to generate negative air ions. Existing methods improve...
