Abstract

The invention discloses an impact-resistant composite insulating material and a preparing method thereof. The insulating material is prepared from 4-10 parts of polyimide resin, 3-6 parts of glass fibers, 5-12 parts of bisphenol-S epoxy resin, 5-15 parts of polycarbonate, 4-8 parts of dodecyl acrylate, 3-7 parts of dodecanol polyethenoxy ether, 2-5 parts of ethylene bis-oleamide, 3-6 parts of styrylphenol polyoxyethylene ether, 4-10 parts of phenolic epoxy vinyl ester resin and 2-5 parts of polyvinyl cinnamate. The preparing method includes the following steps that 1, the components are thrown into a high-speed mixer to be mixed; 2, the insulating material mixture mixed evenly is taken out of the high-speed mixer and extruded through a double-screw extruder; 3, the material extruded in the step 2 is granulated, and the impact-resistant composite insulating material is obtained after the granulated material is cooled to normal temperature.

Description

technical field [0001] The invention belongs to the field of insulating materials, and relates to an impact-resistant composite insulating material and a preparation method thereof. Background technique [0002] In the electrical circuit system, according to the different chemical properties of commonly used insulating materials, it can be divided into inorganic insulating materials, organic insulating materials and mixed insulating materials. The insulating material has a very large resistance to DC current. Under the action of DC voltage, except for a very small surface leakage current, it is actually almost non-conductive. For AC current, there is capacitive current passing through, but it is also considered to be non-conductive. Conductive. The greater the resistivity of the insulating material, the better the insulating performance. Motors and electrical equipment are composed of conductive materials, magnetic materials, insulating materials and structural materials. ...
