Embodiment 1～7 and comparative example 1、2

[0067] The plant-derived oil and polyol ester were mixed in the amounts shown in Table 1 to prepare a base oil, and then the polymethacrylate and other additives shown in Table 1 were added to the base oil. For each lubricating oil combination obtained The materials, as described below, were evaluated for general properties, lubricating properties, combustion properties, and biodegradability. The results are shown in Table 1. In addition, the details of the used vegetable-derived oil, polyol ester, and polymethacrylate are shown below.

Abstract

Provided is a lubricating oil composition having both of improved flame retardancy and biodegradability. The biodegradable lubricating oil composition having flame retardancy comprises: (1) a base oil containing 60 mass% or more of an oil originating in a vegetable oil and 40 mass% or less of a polyol ester, and (2) 0.1-5 mass% of polymethacrylate having a mass-average molecular weight of 20,000 to 300,000.

Description

technical field [0001] The present invention relates to a biodegradable lubricating oil composition having flame retardant properties. In particular, the present invention relates to a biodegradable lubricating oil composition having excellent flame retardancy and high biodegradability, which can be used as a lubricating oil for hydraulic oil, door closer oil, and the like. Background technique [0002] Regarding hydraulic oil, various proposals have been made based on the improvement of its flame retardancy. For example, Patent Documents 1 to 4 respectively propose a self-extinguishing hydraulic oil containing a compound obtained by condensation reaction of hexachlorophosphazene with a perfluoroalkyl alcohol (Patent Document 1); a self-extinguishing hydraulic oil containing a polyol and a partial ester Flame retardant hydraulic oil containing a polymer compound mainly composed of polyol (Patent Document 2); flame retardant by mixing high molecular polymer and low molecular...
