Description
Technical field
The present invention relates to PC Material Fields, refer in particular to a kind of PC materials that may filter that blue light and preparation method thereof.
Background technology
Light is divided into visible ray and black light, and infrared ray, ultraviolet belong to black light, the yellowish green indigo purple light category of blood orange
In visible ray, image and color are formed when injecting macula area, so human body just has vision.Wherein, infrared ray can produce heat energy,
May cause eyes it is scorching hot, burn；Ultraviolet light is stopped by cornea and crystalline, absorbed, and crystalline is with time aging, muddiness, shape
Into cataract.
As for blue light is then that energy is stronger in visible light, including indigo plant, indigo, purple light, and it can not be inhaled by cornea, crystalline
Receive and penetrate cornea and enter macula area with crystalline direct projection, cause the damage of macula area photosensory cell, age macular diseases are just
It is the disease that aging is formed；Modern is because frequently straight for a long time using the 3C products such as computer and intelligent mobile phone, increase
Depending on the chance of LCD screen, also relative increase is endangered by screen blue light.
In order to maintain high brightness, the screen of most 3C products would generally send the blue light more stronger than traditional map pipe,
The blue light that traditional CRT iconoscopes screen is sent accounts for the blue light that 20%, LED LCD screens are sent and accounts for 64%, lithographic plate
The blue light that the screen of the mobile digital devices such as computer, smart mobile phone is sent then is up to 95%；Therefore, have on the market
The filter blue light screen protector used for being attached at screen, avoid causing because of the blue light that eyes Long Term Contact screen is sent
Macular diseases or other disease of eye.
However, current PC materials do not have the function of filter blue light, it needs the filter of covering one blue light on PC materials
Process layer, to manufacturing and using making troubles.
The content of the invention
For further optimization sensor assembly technology, in view of this, the present invention in view of the existing deficiencies of the prior art, its
Main purpose is to provide a kind of material that may filter that blue light, and it can effectively solve existing PC materials and not have blue light filtering function
The problem of.
To achieve the above object, the present invention is using following technical scheme：
A kind of material that may filter that blue light, it includes following raw material：Makrolon 85-95 parts, blue-light absorbers 2-
5 parts and auxiliary agent 3-10 parts.
Preferably, the molecular weight of the makrolon is more than 1.6 ten thousand.
Preferably, the makrolon is aromatic copolycarbonate.
Preferably, the makrolon is bisphenol A polycarbonate.
The blue-light absorbers are yellow chemical powder, preferably phosphor powders.
Preferably, the makrolon, phosphor powders, the ratio of auxiliary agent are：90:4:6.
Preferably, the auxiliary agent is ultra-violet absorber, stabilizer, halogen-free flame retardants, one kind in antistatic additive or more
Kind.
The material of basket light is may filter that more than, present invention further propose that a kind of preparation side for the material that may filter that blue light
Method, it comprises the following steps：
Step 1：Makrolon is dried into 1-2 hours in blast drier at a temperature of 140 DEG C~150 DEG C, it is stand-by；
Step 2：Dry makrolon, phosphor powders and auxiliary agent are weighed by weight ratio to be separately added into high-speed mixer, are stirred
25-60 minutes, discharged after well mixed；
Step 3：Compound is added in double screw extruder, is extruded at 240 DEG C~250 DEG C through melting mixing, cooling granulation,
Blue light material particle is may filter that described in producing.
The particle can be applied on a variety of electronic products after following process, such as LED, car headlight etc..By surveying
Examination, the material that may filter that blue light being prepared due to the addition of a certain proportion of blue-light absorbers, especially phosphor powders, the present invention
Material can filter out the blue light that wavelength is 480-550, without covering a filter blue light process layer in addition on PC materials, be made to production
Make and using very big facility is brought, obtained product can effective protect eyes.
