Description

The preparation method of high high shielding diffuser plate masterbatch and preparation method and diffuser plate thoroughly
Technical field
Embodiments of the present invention are related to field of photovoltaic materials, more specifically, embodiments of the present invention are related to a kind of height The preparation method of high shielding diffuser plate masterbatch, and this masterbatch thoroughly and the method for preparing diffuser plate using the masterbatch.
Background technology
Generally, the backlight module of display device mainly includes that light source, light guide plate, light reflecting board, diffuser plate, brightness strengthen Film.Wherein, light diffusing sheet has the brightness uniformity made from illuminator launching light simultaneously, and covers the functions such as bright rays, and light Diffuser plate also functions to support the effect of other optical thin films.Light source in backlight module is generally divided into full run-down type and side light type, directly Mo(u)ld bottom half is in light sources such as bottom surface of light guide plate cold-cathode tube arranged side by side, LED;Side light type is that the light sources such as cold-cathode tube, LED are configured at leaded light The edge of plate, light passes through from light-guide edge and lights forward.From from the viewpoint of raising backlight briliancy, based on full run-down type Stream, but in recent years, because liquid crystal display, LED television etc. are to slimming development, making the ratio of side light type is increasing.Therefore, it is high saturating The application of high shielding light diffusing sheet will be more extensive.
Polystyrene is because its preferable geometrical stability, heat stability, optics are through characteristic, electrical insulation characteristics and small Moisture absorption tendency, be widely used in diffuser plate making.It is saturating due to its when non-modified polystyrene is used to make diffuser plate Light rate is higher, the disability glare of the exposed LED of meeting.At present photodiffusion material, mainly has by the addition in transparent plastic base material There are the inorganic or organic diffusion particle of different refractivity, including SiO2、TiO2、CaCO2、BaSO4With the inorganic particulate such as glass microballoon Grain, and the organic polymer microparticles such as polymethyl-benzene e pioic acid methyl ester (PMMA, Polymethylmethacrylate), silicones, Reach the purpose for improving material mist degree.
Two the key technical indexes for evaluating photodiffusion material are transmitance and mist degree, the mist degree and transmitance of usual material It is conflicting, traditional photodiffusion material increases the light scattering ability of material and the method for increasing light diffusing agent is usually taken, and Light diffusing agent can cause the decline of transmitance to absorption and covering of light etc..
The content of the invention
Instant invention overcomes prior art transmitance and mist degree are conflicting, mist degree improves the deficiency that then transmitance is reduced, A kind of embodiment of the preparation method of high shielding diffuser plate masterbatch and preparation method and diffuser plate is provided, can with expectation Reduced with solving the problems, such as that diffuser plate mist degree improves then transmitance.
To solve above-mentioned technical problem, one embodiment of the present invention is employed the following technical solutions:
A kind of high high shielding diffuser plate masterbatch thoroughly, it includes following components by weight:
100 parts of polystyrene;
10~11 parts of organic siliconresin;
0.3~0.4 part of titanium dioxide;
0.15~0.2 part of fluorescent whitening agent;
0.02~0.025 part of mineral oil;
The particle diameter of the titanium dioxide is 2~5 microns.
Preferably, the saturating high shielding diffuser plate masterbatch of described height includes following components by weight:
100 parts of polystyrene;
10.56 parts of organic siliconresin;
0.36 part of titanium dioxide;
0.18 part of fluorescent whitening agent;
0.022 part of mineral oil;
The particle diameter of the titanium dioxide is 3~4 microns.
The species and consumption of masterbatch has large effect to the light transmittance and mist degree of diffuser plate, using the former material of aforementioned proportion Material prepares masterbatch, then the transmitance of the diffuser plate prepared with masterbatch up to 68%, and, up to 99%, diffusance is up to 93% for mist degree.
Fluorescent whitening agent can adopt Stilbene-based brightening agent.Present invention employs the titanium dioxide that particle diameter is 2~5 microns As the titanium dioxide that inorganic light diffusing agent, particularly particle diameter are 3~4 microns.Just can make when one side titanium white powder content is relatively low The mist degree of diffuser plate is increased substantially, but transmitance declines very little, on the other hand because the size of titanium dioxide particle diameter is more favourable In being scattered in base material, and the fragility of polystyrene raw material itself can be overcome, therefore the toughness of diffuser plate can be improved.
Further technical scheme is that the titanium dioxide is that its surface is carried out after blending and modifying by silane coupler Modified titanium.Silane coupler can form bonding at the interface of organic filler and inorganic particulate, promote interface fusion, strengthen Performance, can improve dispersibility and bonding force of the titanium dioxide in resin, improve processing performance and improve filled plastics (including poly- Styrene) the performance such as machinery, electricity and weatherability, while and not loss material mechanical property.
The silane coupler can adopt KH550 (gamma-aminopropyl-triethoxy-silane), KH560 (γ-(+)-2,3-Epoxy-1-propanol Ether oxygen propyl trimethoxy silicane), KH570 (γ-(methacryloxypropyl) propyl trimethoxy silicane), KH792 (N- (β-ammonia Ethyl)-γ-aminopropyltrimethoxysilane), any one in DL602, DL171.
Using silane coupler be to the method that titanium dioxide surface carries out blending and modifying by titanium dioxide and silane coupler with 100:1.5 ratio is added in high speed agitator, and high-speed stirred obtains modified titanium in 10 minutes.
Further technical scheme is that the mineral oil is silicone oil or liquid paraffin.Both mineral oil and polyphenyl second Very well, in the masterbatch course of processing, mineral oil easily migrating between phase and phase in mixture can improve for the compatibility of alkene Processing and lubrication, and can be distributed on boundary with more uniform.
A kind of preparation method of high shielding diffuser plate masterbatch, it is comprised the following steps:
(1) by 100 parts of polystyrene, 10~11 parts of organic siliconresin, particle diameter is 2~5 microns of titanium dioxide 0.3~0.4 Part, 0.15~0.2 part of fluorescent whitening agent, 0.02~0.025 part of mix homogeneously of mineral oil obtains feedstock blend;The titanium white Powder is to carry out the modified titanium after blending and modifying to its surface with silane coupler, and the mineral oil is silicone oil (ring-type poly- two Methylsiloxane) or liquid paraffin.
(2) by the raw mixture, extruding pelletization obtains high thoroughly high shielding diffuser plate mother in double screw extruder Expect, each section of temperature of the double screw extruder is:One area's temperature is 170 DEG C;Two area's temperature are 185 DEG C;Three area's temperature are 195 ℃;Four area's temperature are 200 DEG C;Five area's temperature are 210 DEG C;Six area's temperature are 220 DEG C;Seven area's temperature are 210 DEG C;Die head temperature is 210℃。
Preferably, the preparation method of the saturating high shielding diffuser plate masterbatch of described height is comprised the following steps:
(1) by 100 parts of polystyrene, 10.56 parts of organic siliconresin, particle diameter is 3~4 microns of 0.36 part of titanium dioxide, glimmering 0.18 part of optical brightener, 0.022 part of mix homogeneously of mineral oil, obtains feedstock blend;
