Abstract
The invention relates to an anti-radiation plate and a manufacturing method thereof. The anti-radiation plate is characterized by being prepared by adding 2 to 8 percent of wave absorbing material in wood fibers. The wave absorbing material consists of 10 to 50 weight percent of ferrite and 50 to 90 weight percent of nano carbon powder. The ferrite is hexagonal flake magnetoplumbite type ferrite. Compared with the prior art, the anti-radiation plate has the advantages that: 1) the electromagnetic wave absorption efficiency is high, so the harm of indoor electromagnetic waves to human body can be reduced effectively; 2) when addition ratio of the wave absorbing material is between 2 and 8 percent, the rate of the absorption of electromagnetic waves with wavelengths within 200mm and frequencies ranging from 1.0 to 18 GHz is over 80 percent; and (3) when the addition ratio of the wave absorbing material is between 2 and 5 percent and the added amount of the wave absorbing material is reduced, the electromagnetic wave absorbing rate is still over 80 percent, and the cost of the material is lowered at the same time.
Description
Technical field:
The floor that the present invention relates to a kind of radiation proof sheet material and manufacture method thereof and use this radiation proof sheet material.
Background technology:
People are enjoying in convenient that digital information technology brings, also pollute at " wrecking "-electromagnetic wave that is bearing " invisible killer ", along with household electrical appliance, communication equipment, electronic product and electric equipment etc. pour in family, artificial electromagnetic energy is with the speed increase in 10%-15%/year, and electromagnetic pollution has become the fourth-largest pollution sources behind waste water,waste gas and industrial residue.
The people that is mainly derived from that electromagnetic wave pollutes is electromagnetic pollution, mainly contain TV and Radio Service, radio communication transmitting base station, high voltage substation etc., especially Ge Ren wireless communication means and household electrical appliance are to people's harm bigger (near apart from human body), as the operating frequency of electromagnetic oven at 10-30khz, the operating frequency of micro-wave oven is at 2.45GHz, and the mobile communication frequency is many at 2.4GHz.Though radiation intensity can be very big along with the increase decay of distance, some electrical equipment needs nearly body to use, such as electromagnetic oven, mobile phone etc.
At present, protection to a radiation mainly contains two aspects: shielding and absorption, but electromagnetic radiation can not fundamentally be eliminated or weaken to electromagnetic shielding, and aspect construction, one also there is bigger difficulty, reflection electromagnetic wave can superpose with incidence wave simultaneously, causes repeated contamination or destruction to the miscellaneous equipment unit easily.Have only the use electromagnetic wave absorbent material, electromagnetic energy is changed into the energy of other form, just can consume electromagnetic wave.
From to domestic and international association area investigation and analysis, more to the research of absorbing material theoretical performance both at home and abroad, to inhaling the ripple building materials some experimental studies about wave absorption concrete, putty etc. are arranged also, do not inhale the research report of ripple wooden boards, also do not inhale the report of the industrialization of ripple building materials.And use more material in wooden boards to be people the live office activity space, artificial boards such as various particieboards, vegetable fibre board are applicable to makes computer desk, cabinet, furniture etc., if these sheet materials are manufactured to have absorbs the electromagnetic wave feature board, then can effectively reduce of the harm of indoor electromagnetism to human body radiation.
Summary of the invention:
