The invention relates to anhydrous calcium lubricating grease and a preparation method thereof. The anhydrous calcium lubricating grease is prepared from, by weight, 55-85% of base oil, 10-12% of 12-hydroxystearate, 1-5% of calcium hydroxide and 02-0.5% of antioxidant. By improving the production process of the anhydrous calcium lubricating grease, the production process of the anhydrous calcium lubricating grease is simplified, production difficulty is reduced, and production cost is reduced.

Description

A kind of anhydrous calcium base grease and preparation method thereof
Technical field
The present invention relates to technical field of lubricating grease, be specifically related to a kind of anhydrous calcium base grease and preparation method thereof.
Background technology
Anhydrous calcium base grease has good water-resistance and mechanical stability, is difficult to emulsification, has preferable adhesiveness to metal surface, and the stability of colloid is preferable.Anhydrous calcium base grease exceeds more than 50 DEG C than common calcium grease low spot, uses temperature short-term can reach 120 DEG C.Anhydrous calcium base grease production cost is lower by about 30% than 12-hydroxy stearic acid lithium base grease, recently lithium hydroxide price amount of increase is the biggest, causing universal lithium base grease price amount of increase relatively big, more client replaces universal lithium base grease with anhydrous calcium base grease.Anhydrous calcium base grease produces that equipment is simple, and raw material is easy to get, product cost and cheap, from economical and practical, is deeply welcome with user by the producer, so anhydrous calcium base grease is still widely used in China.The most less about technical literature and the patent of anhydrous calcium base grease, lithium base grease CN103555397 discloses anhydrous calcium base grease and preparation method thereof in, and raw material is complicated, and overall refining temperature is higher, causes cost to increase.Anhydrous calcium base grease dropping point disclosed in Chinese patent CN1504552A only has 83 DEG C and 89 DEG C.That this step of aquation is grasped by a lot of LUBRICATING GREASES companies and unskilled, often occur that lubricating grease is softer or does not become fat phenomenon, for above true, a kind of the anhydrous calcium base grease of easy production can become insider's problem demanding prompt solution.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of produce and use cost is low, and the performance anhydrous calcium base grease suitable with prior art and preparation method thereof.
For achieving the above object, the technical solution used in the present invention is:
A kind of anhydrous calcium base grease, is made up of according to following weight percentage following compositions:
Base oil: 55-85%；
12-hydroxy stearic acid: 10-35%；
Calcium hydroxide: 1-15%；
Antioxidant: 0.2-0.4%.
Described base oil is one or both composition of paraffin base mineral oil and naphthenic mineral oil, and when 40 DEG C, kinematic viscosity is 80-350mm2/s。
Described calcium hydroxide is technical grade calcium hydroxide.
Described antioxidant is to dioctyl diphenylamine.
The preparation method of a kind of anhydrous calcium base grease, comprises the following steps: is put in reactor by part basis oil, is warming up to 70-80 DEG C, adds 12-hydroxy stearic acid, insulated and stirred 30min.Calcium hydroxide suitable quantity of water is dissolved, and adds reactor, capping still, stops heating, at this temperature, timing saponification 2h after being warming up to 90-105 DEG C.After completion of the reaction, slowly heat up dehydration 1h-1.5h, opens reaction kettle cover when reactor pressure is zero, it is warming up to 120-130 DEG C, remaining base oil is disposably added reactor, is to slowly warm up to 135-140 DEG C, constant temperature 5min, material in reactor is imported and is in harmonious proportion still and is stirred cooling, when temperature is down to 90-100 DEG C, addition antioxidant, to dioctyl diphenylamine, stirs, homogenizing degassing processes, and obtains anhydrous calcium base grease.
Beneficial effects of the present invention: anhydrous calcium base grease of the present invention has good water-resistance, do not emulsify, metal is had preferable adhesiveness, mechanical stability is good, can meet mechanical friction position lubrication and the requirement protected under moist many water complicated environmental condition, meanwhile, anhydrous calcium base grease preparation method of the present invention is simple, relative to tradition anhydrous calcium base grease, production difficulty and production cost are the most relatively low.
