Example Embodiment

[0014] A health-care graphite nano aluminum powder electromagnetic shielding medium-density fiberboard, which is made of the following parts by weight (kg) of raw materials: wood fiber 100, urea-formaldehyde resin adhesive, graphite powder 22, nano aluminum powder 5, nano tin antimony 5, no Water ethanol 50, nano tourmaline powder 2.3, sodium borohydride 1.5, ascorbyl palmitate 1.3.

[0015] The preparation method of the electromagnetic shielding medium density fiberboard of health-care graphite nano aluminum powder includes the following steps:

[0016] (1) Mix nano tourmaline powder, sodium borohydride, and ascorbyl palmitate evenly, add half of the absolute ethanol with nano aluminum powder, stir evenly, and ultrasonically disperse for 4 minutes to obtain a mixed slurry.

[0017] (2) Drying the wood fiber, spraying the mixed slurry while stirring, and drying to obtain the modified wood fiber;

[0018] (3) Add nano-tin oxide antimony to the remaining absolute ethanol to obtain nano-...

Abstract

The invention discloses a health care graphite nano aluminium powder electromagnetic shielding medium density fiber board, which is prepared from the following raw materials by weight part: 100-110 of wood fiber, a proper amount of a urea-formaldehyde resin adhesive, 22-23 parts of graphite powder, 5-5.5 of nano aluminium powder, 5-5.5 of nano tin antimony oxide, 50-60 of anhydrous ethanol, 2.3-2.6 of nano tourmaline powder, 1.5-1.9 parts of sodium borohydride, and 1.3-1.6 parts of ascorbyl palmitate. According to the invention, sodium borohydride and ascorbyl palmitate are employed to modify nano tourmaline powder, thus improving the dispersibility of nano tourmaline powder, reducing agglomeration and deterioration, promoting homogeneous dispersion of the nano tourmaline powder in wood fiber, achieving uniform emission of negative ions, and being beneficial to human health.

Description

technical field [0001] The invention relates to the technical field of medium-density fiberboards, in particular to a health-care graphite nano-aluminum powder electromagnetic shielding medium-density fiberboard and a preparation method thereof. Background technique [0002] With the construction of electrical equipment such as communication antennas, high-voltage transmission lines, and TV signal towers, and the increase in household appliances, the increasingly serious electromagnetic radiation has caused varying degrees of pollution to the environment. Severe electromagnetic pollution can cause genetic variation, failure to grow or even death of plants; adverse effects on domestic animals, wild animals, etc.; on humans, it can cause central nervous system dysfunction and vegetative nervous disorders mainly caused by sympathetic fatigue and tension. , Electromagnetic radiation endangers human health and pollutes the environment, so the shielding of electromagnetic waves is...
