Densification type high temperature chain lubricating agent composition

The invention relates to thickening high temperature chain lubrication, comprising 50 to 86% low viscosity ester genus oil, 5 to 30% heavy viscous ester genus oil, 5 to 30% polyisobutylene with specified molecular weight and 1 to 5% anti-oxidant, 0 to 3% antiwear agent and 0 to 1% antirust agent, 2 to 5% thickening agent, 1 to 10% colloid supramoly. The consistency of the high temperature chain oil incorporating the invention is 500 to 600 units, the high temperature chain oil is provided with good adhesivity, low volatility and high oxygenize stabilizing ability and is suitable to intermittent manual lubricator situation, also its using temperature can be up to 260 DEG C.
