Method for preparing high-strength heat-conducting composite nylon material from waste carbon fiber reinforced epoxy resin material

The invention provides a method for preparing a high-strength heat-conducting composite nylon material by using a waste carbon fiber reinforced epoxy resin material. The method comprises the following steps: grinding and crushing a waste carbon fiber reinforced epoxy resin material or product into mixed powder by a millstone type solid-phase mechanochemical reactor, adding the mixed powder into a nylon raw material, and preparing the high-strength heat-conducting composite nylon material by a conventional screw extrusion granulation process. According to the method, high-valued recycling of the waste carbon fiber reinforced epoxy resin is achieved, the total recycling concept in the field of material recycling is met, and environmental pollution caused by selective recycling of the waste carbon fiber reinforced epoxy resin in the prior art is avoided. 本发明提供一种利用废弃碳纤维增强环氧树脂材料制备高强导热复合尼龙材料的方法。该方法是先将废弃碳纤维增强环氧树脂材料或制品经由磨盘型固相力化学反应器碾磨粉碎为混合粉体，在尼龙原料中添加该混合粉体，经常规螺杆挤出造粒工艺，制备得到高强导热复合尼龙材料。该方法实现了废弃碳纤维增强环氧树脂的高值化回收利用，符合材料回收领域中的
