Abstract

The invention aims to provide a nanometer modified rapid prototyping polymer insulating material. The nanometer modified rapid prototyping polymer insulating material specifically comprises the following components in percentage by mass: silicone rubber, nano-zinc oxide and nano-silicon dioxide. According to the invention, 2.4%-7% by mass of the nano-zinc oxide and 1.2%-7.2% by mass of the nano-silicon dioxide are added into the silicone rubber, so while the insulating property of a silicone rubber material is maintained, the gelation and curing temperature conditions of the silicone rubber material are improved, the gelation and curing time of the silicone rubber material is shortened, and the heat-conducting property and the aging resistance of the insulating material are enhanced. The invention also provides a preparation method of the nanometer modified rapid prototyping polymer insulating material.
