In order to realize the door closer function, the oil is required to be capable of keeping the kinematic viscosity of the oil from obviously changing in the use process all the year round (the use temperature is usually-35-45 ℃), the oil has higher fluidity, the door closing force and speed are ensured to be stable and consistent in use of the door closer, the impact between a door and a door frame and the deformation of the door body caused by the poor buffer effect are avoided, and therefore the oil has excellent viscosity-temperature performance; meanwhile, the oil product is required to have excellent anti-foaming performance and air release performance, so that the stability and smoothness of the damping force during door closing are ensured, and abnormal sound is not generated; the door closer comprises a sealing material, so that the oil is required to have adaptability and compatibility with the sealing material, otherwise, the accelerated abrasion of the sealing part of the door closer is easily caused, the oil leakage of internal fluid is caused in the throttling process, and the hydraulic system fails; in addition, the oil product with good wear resistance protects related parts in the working process of the door closer, and reduces oil leakage and high temperature generated by friction and wear, so the oil product has excellent oxidation resistance and service life; the most important is that the oil product has excellent shearing resistance in the throttling process of the oil product through the small holes on the premise of meeting the requirement of high viscosity index and keeping excellent viscosity-temperature performance.
By combining the structural characteristics and the use requirements of the door closer, the door closer oil requires that the oil product has a high enough viscosity index, excellent anti-foaming performance, air release performance, abrasion resistance, oxidation resistance and shearing resistance, and has good adaptability to contact materials.
In CN1952091, a hydraulic oil composition suitable for door closer is introduced, although viscosity index is greatly improved, shear loss rate is larger. Although CN102812114A can have certain biodegradability by selecting special base oil, the viscosity retention capability of the viscosity under different temperature environments is not ideal.
Disclosure of Invention
The invention aims to provide door closer oil with excellent viscosity-temperature performance, which is greatly improved in wear resistance and oxidation resistance, prolongs the service life of a door closer and has excellent shear resistance.
In order to achieve the aim of the invention, the door closer oil composition provided by the invention comprises the following components in percentage by weight: the alkyl side chain R is C8～C14The content of the PMA type adhesive is 5-20%, and the content of the antiwear agent is0.8-3.2% of sulfurized isobutylene with the sulfur content of 30-55%, 0.05-1.1% of benzotriazole octadecylammonium salt serving as a friction modifier, 0.05-0.5% of 2, 6-di-tert-butylphenol and dioctyl diphenylamine compounded according to the proportion of 1: 3-3: 1, 0.05-1.2% of pour point depressant, 0.012-1.0% of ethylene glycol serving as an anti-emulsifier, 0.0002-0.008% of anti-foaming agent methyl silicone oil and the balance of mineral type base oil and/or poly-alpha-olefin base oil.
The door closer oil composition disclosed by the invention has excellent viscosity-temperature performance, high wear resistance, high oxidation resistance and the like.
