Background
Along with social progress and improvement of urbanization level, application occasions using the door closer are more and more, particularly, the use frequency of occasions such as some markets, individual door heads and the like is higher, the door closer oil achieves a buffering effect through the throttling effect of the valve and the hole, stable door closing and door frame and door body protection are automatically realized, and the occasions have the risk of firing, so that the door closer oil is required to have a certain flame retardant effect in case of fire.
According to the working characteristics of a door closer, the change of kinematic viscosity of oil products is required to be reduced in the four-season transformation process, excellent fluidity is maintained, the door is opened and closed stably and continuously, and the oil products are required to have excellent viscosity-temperature performance, low-temperature performance and oxidation resistance.
CN106867631 a special lubricating oil for door closer introduces a composition suitable for door closer, although viscosity index is greatly improved, gear oil complexing agent is used, because of sulfur, it has a strong pungent taste. CN102812114A has certain biodegradability through selecting special base oil
