Abstract
The invention relates to an engineering plastic material. The engineering plastic material is prepared from, by weight, 60-80 parts of PU resin, 20-30 parts of terpene resin, 10-40 parts of modified glass fiber, 12-18 parts of carbon black, 10-15 parts of talcum powder and 1-3 parts of antioxidant. Specific PU resin and terpene resin are matched and mixed with a specific reinforcing agent, an anti-ageing agent and filler to obtain engineering plastic with excellent mechanical strength and elasticity. As terpene resin is added, mechanical strength and tenacity of the engineering plastic can be improved, and cracking of the engineering plastic in machining is prevented.
