Description

Preparation method of graphene surface modified micron-sized tourmaline negative ion release functional powder
Technical Field
The invention belongs to the field of composite materials, and particularly relates to a preparation method of graphene surface modified micron-sized tourmaline negative ion release functional powder.
Background
Since Elster and Gertel discovered the existence of negative ions in the air in 1889, Ashkinass et al further determined their biological significance in 1902, Philipp-Laonena Ph listed a large number of facts in 1930, after their effects of resisting diseases and delaying aging, many scholars continuously invested in the study of negative ions, raising a wave tide once. In 1932, Hammon of CRA corporation, USA, produced the first anion generator worldwide, which opened a new chapter for human use of artificial anions to improve the environment, prevent diseases, and treat diseases. Electrolysis of H with tourmaline was studied by Ku-bo in 19982O, H is generated in the experimental process2Thus, it was found that the natural ore has a function of generating negative ions, which is very important for improving the environment habitability.
The research on air anions in China begins in 1978, and the research progress of the influence of the anions on human health and the publication of related papers are marked by Xian-Bo. Subsequently, the progress of biomedical experimental research is promoted, the environmental protection and health consciousness of people is improved, ion detection instruments are improved, the research of people on the action mechanism of negative ions is accelerated, and the production and the application of the generator are promoted.
Zhang Kairun et al adds anion additive into PET polymerization process by copolymerization method to obtain polyester slice, then prepares anion far infrared flame-retardant fiber by melt spinning, the anion generation amount of the obtained fiber is 23/cm3And the mechanical property is better. Natural ore (opal) is processed into nano material by Liu Yaguang, etc. and then mixed with special high molecular resin, and the cotton quilt is subjected to negative ion far infrared after-treatment, so that the emissivity of the cotton quilt can reach 88%, and the cotton quilt can play an effective health-care role. Studies such as Cheng et al find that when the content of germanium is 3 percent in the preparation of PCT/germanium composite fiber, the release amount of negative ions can reach 1470 ions/cm3. The lowest anion generation amount of the functional home textile fabric is 3000 anions/cm3. The function and the advantages of the ecological negative oxygen ions are numerous, and part of the function mechanisms are as follows:
(1) purifying and dedusting:
small particulate matters (such as PM2.5) in the air are mostly provided with positive charges, and negative ions are easy to adsorb and agglomerate the small particulate matters into large-particle dust, so that the large-particle dust is naturally settled, and the dust removal effect is achieved.
(2) Sterilization and antibiosis:
the negative ions with high activity have good oxidation-reduction effect, can be combined with bacteria, microorganisms and the like in the air to destroy the cell function or the activity of active enzyme, disturb the growth of thalli and kill the thalli, and achieve the aim of resisting bacteria and sterilizing.
(3) Oxidation resistance and aging prevention:
the radical containing unpaired electrons can capture electrons of other substances to cause oxidation in order to ensure self-stability. The increase of free radicals in human bodies can cause cell aging and even death, weaken the immunity of human bodies and finally cause various diseases. The negative ions can enhance the permeability of the original plasma membrane, amplify cells, enable nutrient substances and metabolic wastes to smoothly enter and exit the cell membrane, and enable the operation of a sodium-potassium pump on the cell membrane to be smoothly started, thereby facilitating the exchange of substances inside and outside the cells.
At present, most of anion products in the market only have a health care function, and the main reasons are as follows:
(1) the negative ion generator needs to depend on a high-voltage power supply, harmful ozone molecules can be generated in operation, most of released negative ions have large particle sizes and are not easy to absorb by a human body, and the negative ion generator can be mainly used for removing dust.
(2) For example, germanium products, teflon products and the like, the generation amount of negative ions is not enough or high-frequency friction is needed to generate the negative ions, and the required amount is difficult to achieve.
