Preparation of Polyurethane Modified Epoxy and Its Application in Sports Equipment
Epoxy is a thermosetting resin with high electrical insulation and mechanical strength,but its impact resistance is weak,with high brittleness and so on.In order to further enhance its impact resistance,the epoxy was modified with different polyurethan,and the corresponding modification process was analyzed.At the same time,the application of modified epoxy in sports equipment such as skateboard,ball and sports protective gear was discussed in detail.
