Lubricating spray coating for automotive constant-velocity universal joint

Abstract

The invention relates to the technical field of automotive repairing and maintaining, and particularly relates to lubricating spray coating for an automotive constant-velocity universal joint. The lubricating spray coating is prepared from the following raw materials in parts by weight: 25-40 parts of carbon nitride, 50-80 parts of polyethylene glycol, 45-60 parts of borate, 10-18 parts of molybdenum containing phenolic resin, 20-40 parts of high-activity polyisobutylene succinimide, 5-10 parts of sodium hexametaphosphate, 5-15 parts of vegetable oil and 20-30 parts of a curing agent. The lubricating spray coating breaks through the situation of inconvenient use of traditional lubricating paste for an automotive constant-velocity universal joint, is more convenient by adopting a mode of the lubricating spray coating for an automotive constant-velocity; and the application amount of chemical engineer oil is reduced due to the use of the vegetable oil of biomass, so that the coating is environment-friendly; the coating has a lubricating effect by adding the curing agent, and has a maintaining effect, so that the service life of a constant-velocity universal joint can be prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile repair and maintenance, in particular to a lubricating spray paint for constant velocity universal joints of automobiles which is green and environmentally friendly and has maintenance functions. Background technique [0002] Constant velocity universal joints are widely used in the automobile industry. Modern cars generally pursue the comfort and durability of vehicles, and put forward higher requirements for constant velocity universal joints: such as long life, low vibration, low noise and other performances, can be stable transmit power. In addition to improving from the perspective of product structure, since friction and lubrication directly determine the service life and performance of constant velocity joints, it is necessary to focus on research on the friction and lubrication performance of constant velocity joints. At present, the lubricants for constant velocity joints in the marke...
