Embodiment 1- Embodiment 6

[0053] The preparation methods of the PC solar panels in Example 1-Example 6 are all the same, the only difference is that the types and dosages of the raw material components in the main material layer are different, see Table 2 for details:

[0054] Table 2, the type and dosage of raw material components in the main material layer

[0055]

[0056] The hydrophobic agent in Example 1-Example 6 includes polyvinyl fluoride and ethylene-tetrafluoroethylene copolymer in a weight ratio of 1.3:2.5.

[0057] The thickness of anti-ultraviolet layer in embodiment 1-embodiment 6 is 50 μ m, the raw material of anti-ultraviolet layer in embodiment 1-embodiment 3 is phenyl o-hydroxybenzoate, the thickness of anti-ultraviolet layer in embodiment 4-embodiment 6 The starting material is 2-hydroxy-4-n-octyloxybenzophenone.

[0058]Taking Example 5 as an example to illustrate the preparation method of PC solar panels, it may further comprise the steps:

Abstract

The invention relates to the field of PC solar panels, and specifically discloses an aging-resistant PC solar panel and a preparation method thereof. The anti-aging PC sunlight board includes a main material layer, an anti-ultraviolet layer covering the upper surface and the lower surface of the main material layer; the main material layer is made of the following raw materials by weight: polycarbonate; organic montmorillonite; hydrophobic agent; Oxygen agent; its preparation method is: mix the raw material components in the main material layer uniformly to form a primary mixture; put the primary mixture and the anti-ultraviolet layer raw materials into the extruder for high temperature melting, and adopt the co-extrusion process to melt the melted anti-ultraviolet The raw materials of the ultraviolet layer cover the upper surface and the lower surface of the primary board formed by extruding the primary mixture, and after cooling, the final product is obtained. The aging-resistant PC solar panel of the present invention has better aging resistance; in addition, the preparation method of the present invention has a simple manufacturing process, and at the same time can ensure that the obtained PC solar panel has the advantages of better aging resistance.

Description

technical field [0001] The invention relates to the field of PC solar panels, more specifically, it relates to an aging-resistant PC solar panel and a preparation method thereof. Background technique [0002] Polycarbonate (PC) is an important thermoplastic engineering plastic developed in the late 1950s. It has excellent and balanced mechanical, thermal and electrical properties, especially the impact strength is the crown of general thermoplastics, and is widely used in the production of various Sunshine panels and endurance panels can be used to make carports, balcony canopies and greenhouse lighting carports. [0003] The existing Chinese patent application publication number CN108047681A discloses a PC polycarbonate solar panel capable of sound and heat insulation. 10-18 parts of ether sulfone, 2-5 parts of formaldehyde scavenger, 30-40 parts of melamine resin, 1-2 parts of plasticizer, 1-2 parts of dispersant, 0.5-1 part of antioxidant, 0.5-1 part of modifier share. ...
