Problems solved by technology

[0004] Among them, the open gear grease mostly uses mineral oil as the base oil. The disadvantage of the base oil is that the base oil has limited viscosity and poor viscosity, and cannot form a thick oil film when the oil is thrown away. Poor biodegradability and pollution to the environment

Abstract

The invention relates to a special lubricant named as HP800 Special Lubricant which is used for the open gear and support roller that are oiled by injection method. The lubricant takes composite calcium sulphonate and composite aluminium as the thickener; the base oil of the lubricant is synthetic oil; and in addition tackifier, extreme pressure agent and antioxidant are also added in. Wherein the weight-portion of each component are: the base oil: 50-64, the thickener: 20, the tackifier :5-10, the extreme pressure agent: 10-25,and the antioxidant: 1. The invention is suitable for lubrication of the open gear, the support roller of all kinds of umbrella ball mill, mixer, rotary kiln, imported umbrella excavator, crusher, and coal grinding machine; and has very high extreme-pressure performance, excellent viscosity and protection performance, thereby the invention can substitute import products of the same kind and has the advantages of thick oil-film, non-oil-swinging and environmental-protection.

Description

technical field [0001] The invention relates to a special lubricant, the product name is HP800 special lubricant, which is used in open gears, rollers and other parts, and is lubricated by spraying. Background technique [0002] Generally, there are two types of lubrication products for open gears: oil type and grease type. [0003] Among them, the composition of open gear oil is made by mixing asphalt and mineral oil and adding extreme pressure agent, antirust agent and antioxidant. The disadvantages are that the asphalt in the product pollutes the environment, has poor high temperature resistance, poor viscosity, and often throws oil and flows, which will bring troubles to on-site maintenance. Basically, it is an obsolete product. [0004] Among them, the open gear grease mostly uses mineral oil as the base oil. The disadvantage of the base oil is that the base oil has limited viscosity and poor viscosity, and cannot form a thick oil film when the oil is thrown away; the...
