Abstract
The invention relates to the field of carbon brush technology, in particular to a carbon brush used for anti-overheating flashover motor and mixed with six potassium titanate whisker and a preparation method. In the carbon brush, middle-temperature coal tar pitch, ethane-vinyl acetate copolymer and epoxy resin are mixed and used as bonding agent. The composite binding agent is highly compatible to raw materials, highly adhesive, not liable to age and crack. The mixed six potassium titanate whisker has higher mechanical and physical performance, and is provided with thermal insulation, enhancement and abrasion resisting effects, so using performance of the carbon brush is improved and overheating and flashover problems occurring in the using process of the carbon brush are effectively overcome. Via the addition of the nanocarbon sol, electrical conductivity of the carbon brush is improved, and abrasion resisting ability is enhanced. The prepared carbon brush has high performance, operates stably and is highly efficient and durable.
Description
Technical field
