AI Technical Summary

Problems solved by technology

However, PC, like other organic polymer materials, will degrade under the action of ultraviolet rays. The degraded PC reacts with oxygen or other active components in the air, resulting in yellowing, while the light transmittance, gloss and strength and toughness will be greatly reduced

Abstract

The invention provides an anti-aging PC (polycarbonate) sun board and a preparation method thereof. The PC sun board is prepared from raw materials including PC, polyethylene, butadiene styrene rubber, polyethylene glycol, glass fiber, stearic acid, a plasticizer, a dispersant, a filling material, an antioxidant, a silane coupling agent and pentaerythritol tetrastearate. The preparation method comprises steps as follows: firstly, PC, polyethylene, the butadiene styrene rubber, polyethylene glycol, the glass fiber, stearic acid, the plasticizer, the dispersant, the filling material, the antioxidant, the silane coupling agent and pentaerythritol tetrastearate are added to a stirrer, heated and subjected to thermal insulation, then an obtained mixture is introduced to a double-screw extruder and subjected to melt blending extrusion, traction, granulation and injection molding and the anti-aging PC sun board is obtained. Polyethylene, the butadiene styrene rubber and PC are matched to serve as a matrix, the glass fiber is added, the prepared PC sun board has excellent anti-aging performance, and the color difference and the notch impact strength retention rate are relatively high after the PC sun board is aged for 400 h.

Description

technical field [0001] The invention belongs to the technical field of solar panels, and in particular relates to an anti-aging PC solar panel and a preparation method thereof. Background technique [0002] PC sunshine board is a kind of engineering plastic sheet made of polycarbonate resin (Polycarbonate) by extrusion molding method. Polycarbonate has good light transmission, and its board is mostly used for building lighting and agricultural greenhouses, so it is called It is a PC solar panel. As a new type of building material that has emerged in recent years, PC sunshine board has good light transmission, super impact resistance, excellent crush resistance and abrasion resistance, and its impact strength is more than 250 times higher than that of ordinary glass. At present, it has been widely used in roofs, curtain walls, partitions, lighting facilities and advertising signs of industrial, agricultural, civil and public buildings, and its application fields are very bro...
