Description

Technical Field

[0001] The invention relates to the field of nanoparticle materials, and in particular to an ultrafine nanoparticle material and a preparation method thereof. Background Art

[0002] Nanoparticles, also known as ultrafine particles, refer to particles with a size between 1 and 100 nm, which belong to the category of colloidal particle size. They are in the transition zone between atomic clusters and macroscopic objects, between microscopic systems and macroscopic systems, and are composed of a small number of atoms or molecules. Nanoparticles are divided into metal nanoparticles, ceramic nanoparticles, and polymer nanoparticles. The polymer nanoparticles in the prior art are mainly composed of polylactic acid, polyethylene, and polystyrene, and have low dispersion stability, filling effect, flexibility, and elasticity, resulting in unsatisfactory application effects. Based on the above, we propose an ultrafine nanoparticle material and a preparation method thereof. Summary of the invention

[0005] Preferably, the polyvinyl ether dispersant can improve the dispersibility of the nanoparticles in the medium, so that the material has better uniformity, and the silica filling reinforcing powder can significantly improve the strength and rigidity of the material.

[0006] Preferably, the polysiloxane rubber is ultrafine particle polysiloxane rubber.

[0007] The present invention also proposes a method for preparing ultrafine nanoparticle material, comprising the following steps:

[0009] S2: Add 3% organic pigment and 20% polyvinyl ether dispersant into the mixer, and mix them with the ultrafine particle polymer formed in S1 at high speed for 30 minutes to make the pigment evenly dispersed and fused;

[0010] S3: The ultrafine particle polymer dispersed in S2 is subjected to nano-level grinding by a grinder to obtain ultrafine nanoparticle material.

[0011] Preferably, in S2, before adding the organic pigment and the polyvinyl ether dispersant, the speed of the stirrer in S1 needs to be adjusted to 1800-200 r / min.

[0012] Preferably, in S3, the grinder is a three-roll grinder, and the three-roll grinder grinds the ultrafine polymer particles in one pass and two passes until the particle size of the ultrafine polymer particles is within the range of 50 um.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The ultrafine nanoparticle material prepared by the present invention can improve the dispersion stability of the ultrafine nanoparticle material in the medium by adding organic pigments and polyvinyl ether dispersants, so that the material has better uniformity, and the addition of silicon dioxide filling and reinforcing powder can improve its filling effect, thereby improving the strength and rigidity of the material.
