Problems solved by technology

Although ATO can be better dispersed in PC, this process is relatively complicated, and another polymer material is introduced, which will inevitably lead to compatibility problems with PC resin, cause interface effects and reduce transparency, etc.
However, it is well known that pure PC resin has relatively poor fluidity, which makes processing more difficult, and the above-mentioned method still has the problem of difficult processing.
Therefore, how to find a way to mix ATO uniformly into the PC solar panel in a nano-dispersed manner without introducing other polymers to reduce the transparency of the PC solar panel, and at the same time improve the fluidity for easy processing is urgently needed. of

Embodiment 1

[0041] ATO modification: add dispersant KH570 (Sinopharm Chemical Reagent Co., Ltd.) accounting for about 1.0% of the mass of ATO (Shanghai Huzheng Nano Co., Ltd.) into distilled water and stir, then add ATO to form a suspension with a solid content of 30%. Liquid, adjust suspension pH to 10 with 1M NaOH solution, modify ATO with ball milling method (ball mill model QM-2SP12, ball milling beads are zirconium beads with a particle diameter of 1mm, ball mill rotating speed 380rpm, ball milling time 7.5h) to obtain slurry, adjust Adjust the pH to about 8.0 (see the particle diameter of ATO in the slurry figure 2 a). Then, the nano-dispersed ATO slurry was evaporated to dryness at about 45° C. in a rotary evaporator, and then ground to obtain ATO nanoparticles.

Embodiment 2

[0043] Dispersant KH570 is changed into KH560 (Sinopharm Group Chemical Reagent Co., Ltd.), and the usage amount is changed into 1.8% of the ATO quality simultaneously, and other is the same as embodiment 1, obtains slurry and adjusts pH to be adjusted to about 8.0 (the particle diameter of ATO in the slurry sees figure 2 b).

Embodiment 3

[0045] The dispersant stearic acid of 0.2g is added in 80g dehydrated alcohol and stir, then add the ATO of 20g (Shanghai Huzheng Nano Co., Ltd.), modify ATO with ball milling method (ball mill model QM-2SP12, ball milling beads are particle diameter 1mm zirconium beads, ball mill speed 380rpm, ball milling time 2.5h) to obtain the absolute ethanol slurry of ATO. Then, the nano-dispersed ATO slurry was evaporated to dryness in a rotary evaporator at about 30° C. and ground to obtain ATO nanoparticles.

Abstract

The invention discloses a special master batch for a PC (Polycarbonate) sunlight board and application thereof. The preparation method of the special master batch for PC sunlight board comprises the following steps of: (1) carrying out nano dispersion and modification to dispersing agent, the ATO (Arsenic Trioxide) content of which accounts for 0.1%-10% of the mass of the ATO to obtain ATO nanoparticles, wherein the dispersing agent is a silane coupling agent or stearic acid, and the ATO is stibium-doped stannic oxide; and (2) fusing and mixing the ATO nanoparticles in PC resins to prepare the special master batch for PC sunlight board, wherein the mass fraction of the ATO is 1%-50%. The master batch has high processing fluidity and is suitable for preparing the PC sunlight board with higher transparence and good heat-insulation effect.

Description

(1) Technical field [0001] The invention relates to a special masterbatch for PC solar panels and a preparation method for PC solar panels. (2) Background technology [0002] PC sunshine board is a new type of building material, which has the advantages of transparency, light weight and low price. But when it puts in visible light, it also lets in infrared light, that is, the main heat source light in sunlight, that is, its heat insulation performance is poor. [0003] ATO (antimony-doped tin dioxide) is a material with special photoelectric properties. The homogeneous dispersion of nano-ATO into PC (polycarbonate) can make PC solar panels have good transparent and heat-insulating effects. In the patent application CN101421353A, ATO is firstly modified with a polymer dispersant to obtain modified ATO particles, and then mixed with PC, and small molecule additives are also added to extrude to obtain a PC composite material. Although ATO can be better dispersed in PC, this p...
