摘要
聚酯树脂是热固性树脂在工业中应用最广泛的品种之一,使用异氰酸酯对其进行嵌段改性可以解决普通聚酯树脂固化后脆性大、收缩率高、耐冲击性差及力学性能差等缺点。本文设计了一系列不同的聚酯与异氰酸酯改性,并将其制备成预浸料作为光伏板基板。通过性能表征可知,使用异氰酸酯改性树脂制备的玻璃纤维增强光伏板具有轻质、机械强度高、光透过率高、水汽阻隔效果好、耐黄变、层间不易分层、可靠性佳等特点,其性能远优于普通光伏板性能。
Polyester is not only one of the most widely used varieties of thermosetting resin in the industry,but also the first of the three major matrix resin of composite materials.The block modification of isocyanate can solve the disadvantages of large brittleness,high shrinkage rate,poor impact resistance and poor mechanical properties of ordinary polyester resin after curing.This paper designed a series of different polyester and isocyanate modification,and prepared into prepreg as photovoltaic panel substrate.Through performance characterization,the photovoltaic panel modified by isocyanate has the characteristics of light weight,high mechanical strength,high light transmittance,good water vapor barrier effect,yellowing resistance,not easy stratification between layers,good reliability and so on.The performance is far better than that of ordinary photovoltaic panels.
