摘　　要：热板焊接是目前塑料焊接中最普遍且经济的一种焊接手段,而玻纤复合材料在热板焊接过程中存在焊接强度差,焊接面溢料等一系列问题。通过分析焊接性能不同的两种样品,发现:熔体流动前沿玻纤与树脂的分离程度是影响玻纤增强聚丙烯材料焊接性能的关键因素。研究了相容剂对热板焊接性能的影响,并提出相容剂含量调控熔体流动前沿玻纤与树脂的分离程度的思路,实现了保持材料机械性能无显著衰减的同时大幅度提升材料的热板焊接性能。Hot plate welding is the most common and economical welding method in plastic welding at present,but glass fiber composites(especially glass fiber reinforced polypropylene)have a series of problems in hot plate welding,such as poor welding strength,welding surface overflow and so on.By analyzing two kinds of samples with different welding properties,it found that the separation degree of glass fiber and resin the key factor affecting the welding properties of glass fiber reinforced polypropylene.
