摘要
The invention is about a process to recycle cured thermoset plastic. The process involves using a small quantity of thermoplastic and mixing it with cured thermoset plastic (about 70% (minimum) by weight of all ingredients used) under heat and pressure. A chemical, i.e. a thermoplastic polymer grafted with functional group, is added to create the bonding between the thermoplastic and cured thermoset plastic used; and lubricants are also added to improve the process and enhance the quality of the end product. Although the end product has cured thermoset plastic as a main constituent, it behaves like thermoplastic. It can undergo reversible physical change: i.e. it can change its physical state from solid to molten under heat; and then reverse itself back to solid when heat is removed. The physical change may be repeated without any noticeable change or deterioration in the end product.
