Description
Technical field
The present invention relates to optical resin compositions field, in particular to optics polystyrene resin compositions and its
The light guide plate of formation.
Background technique
The main function of light guide plate be will be to turn linear light source from the light guide that the light source of side issues to liquid crystal display panel
Become area source, in TV, the display of desktop personal computer, subnotebook PC, mobile phone, auto navigation (car
) etc. navigation used in extensive uses.In the prior art, light guide plate uses always with PMMA (polymethyl methacrylate)
For the allyl resin of representative, but water imbibition is high, therefore the case where there is the problem of molded product bends or size to change.
On the other hand, although it is low as the phenylethylene resin series water imbibition of raw material using styrenic monomers, it can occur in long-term use
Heated discoloration phenomenon, molded product xanthochromia and lead to decrease in transmission.
Summary of the invention
The purpose of the present invention is to provide one kind to be capable of the optics polyethylene-based resin composition of long-time resisting etiolation, with
And the light guide plate formed with it.
What the present invention was mainly realized by following technical scheme.
A kind of optics polystyrene resin compositions, which is characterized in that calculate by percentage to the quality, including such as the following group
Point：The phenylethylene resin series that 88%~99.8% weight average molecular weight is 250,000~700,000,0.05%~3% antioxidant,
0.05%~3% ultraviolet absorbing agent, 0.05%~3% light stabilizer.
Specifically, a kind of light guide plate, is formed by above-mentioned optics with polystyrene resin compositions.
The method have the benefit that：The present invention passes through steady antioxidant, light to be added in polystyrene resin
Determine agent and polystyrene system: compositions are prepared in ultraviolet absorbing agent, it is not flexible, there is excellent colorless transparency, fit
Optical applications for light guide plate etc..Also, forming the coloring in contour thermal environment prevents effect high, and yellow value is low,
Retarding ageing prolongs the service life.
Specific embodiment
Hereinafter, implementation form of the invention is described in detail.
Optics of the invention polystyrene resin compositions include polyethylene-based resin, antioxidant, ultraviolet light suction
Receive agent, light stabilizer and clarifier.
