Material stamps leaded light in the acryl plates bottom surface laser engraving, V-type cross grid engraving, UV screen printing technology of optical grade
Point.The light issued from lamp is drawn in the stop on optical grade acryl plates surface using optical grade acryl plates, works as light
When being mapped to each light guiding points, reflected light can be spread toward all angles, then destroyed conditioned reflex and projected by light guide plate front.Pass through
Various densitys, light guiding points not of uniform size, can make light guide plate uniformly light-emitting.
But existing light guide plate has many disadvantages, and acrylic board plasticity is not strong, can not make peculiar different of forming shape
Shape light guide plate, it is difficult to meet the diversified life requirement of people；Acrylic board price is relatively high, causes the leaded light thus produced
Plate price is also higher；Acrylic board is difficult to degrade, and does not meet the developing policy of nation-building environment-friendly type society, brings to environment
Pressure.
Summary of the invention
The object of the present invention is to provide a kind of composition for preparing light guide plate, the light guide plate plasticity thus prepared is strong,
It is guide-lighting uniform, it is environmental-friendly.
The purpose of the present invention is what is realized by following technological means:
A kind of composition preparing light guide plate, the composition is with polyethylene terephthalate (PET) or poly- cream
Sour (PLA) is base-material, and guide-lighting powder and heat stabilizer is added；The content of guide-lighting powder is 0.1-4%, heat stabilizer in the composition
Content be 0.1-4%, remaining as base-material；Viscosity is 0.5-0.8dl/g to the composition after mixing.
It further include transparent mica stone powder in above-mentioned composition, the content of the transparent mica stone powder is 1-15%.
It further include titanium dioxide in above-mentioned composition, the content of the titanium dioxide is 0.1-1%.
Above-mentioned leaded light powder is transparent microballon, is selected from silica, barium sulfate or organosilicon.
Above-mentioned heat stabilizer is selected from the lipid of phosphoric acid, phosphorous acid or phosphoric acid phosphorous acid.
Above-mentioned transparent mica stone powder is nano transparent mica stone powder.
The plane of incidence of above-mentioned light guide plate is set as physics refractive power face, and transmission plane is set as dull surface, the physics refractive power face
Refer to and the plane of incidence is engraved as to different patterns, different concaveconvex structures makes the light for being incident on light guide plate that different angle occur
Refraction.
The present invention having the beneficial effect that compared with the existing technology:
1, the present invention uses PET as base-material, and compared to acrylic board, cost is lower, and plasticity is stronger, can satisfy
Diversified demand of the people to different shape lamps and lanterns.
2, PLA also can be used as base-material in the present invention, and compared to acrylic board, PLA is biodegradable, is more in line with state
The environmental requirement of family.
3, the present invention makes the light for injecting light guide plate that the refraction of multi-angle occur by the way that guide-lighting powder is added, improve PET and
The guide-lighting mildness of PLA light guide plate and guide-lighting uniformity；The present invention solves PET and PLA light guide plate by the way that heat stabilizer is added
Problem easy to change in production；The present invention controls the quality and plasticity of plate forming by the viscosity of control composition.
4, the present invention improves the glassy state temperature of light guide plate, the glass of PET material by the way that transparent mica stone powder is added
State temperature is 60 DEG C, and the glassy state temperature of PLA material is 57 DEG C, so that it is improved 3-5 by the way that transparent mica stone powder is added
DEG C, to increase light guide plate in the heat resistance used.
5, the present invention further increases the guide-lighting mildness and guide-lighting uniformity of light guide plate, together by the way that titanium dioxide is added
When titanium dioxide also add the whiteness of light guide plate.
