Preferably, the commercial model of the toughening agent is YKL-1155.
Preferably, the talcum powder is GY 950.
Preferably, the curing agent is BPO-75W.
The invention also provides a preparation method of the aramid fiber putty, which comprises the following steps:
the method comprises the following steps: mixing and stirring aramid fiber, unsaturated polyester resin, cobalt naphthenate drier, air drier and curing agent for 10-15min, and then adding a toughening agent to obtain a premix;
step two: adding talcum powder into the premix obtained in the first step, and stirring for 40-60min by a high-speed dispersion machine to obtain a mixture;
step three: and (5) grinding the mixture obtained in the step two in a grinder for 3-8min to obtain the aramid fiber putty.
