Description

A kind of die cast metal heat resisting lubricating agent and its preparation and application
Technical field
The present invention relates to be machined auxiliary agent field, more particularly, to a kind of die cast metal heat resisting lubricating agent and its preparation With application.
Background technology
Releasing agent is a kind of functional materials between mould and finished product, with heat-resisting and stress performance, is difficult point Solution is worn and torn, it is ensured that workpiece is smoothly separated from mould.Extension die life.State according to releasing agent can divide It is aqueous release agent, oil-based release agent, the class of solid releasing agent three.Current China using it is most be aqueous release agent, it is this kind of de- Mould agent is used mostly vegetable oil, paraffin etc. as lubrication and the active ingredient of the demoulding, adds assistant for emulsifying agent etc. and is made.This kind of demoulding The poor heat resistance of agent, may be only available for the low temperature demoulding.And for large and medium-sized intricate casting because the cast temperature that it needs is high, this Class releasing agent moment volatilizees, it is impossible to form fine and close film, it is impossible to greasy property is provided, accordingly, it would be desirable to a Good Heat-resistance Releasing agent.Also there is a serious defect in such releasing agent overseas market, its stability is poor, and service life is short.
Therefore, a releasing agent for having heat-resisting and stability concurrently for problem above is worth research.
The content of the invention
Goal of the invention：In order to solve the problems of in the prior art, it is good, steady that the present invention proposes a kind of heat resistance Qualitative good, simple when being provided simultaneously with excellent greasy property, long service life and using, safety, environmental protection is applied to various big-and-middle The die cast metal heat resisting lubricating agent of the type complexity metal casting demoulding and its preparation and application.
Technical scheme：To achieve these objectives, the present invention takes following technical scheme：
A kind of die cast metal heat resisting lubricating agent, it is calculated by mass including the following raw material component：
It is more highly preferred to, the detersive is middle base number calcium mahogany sulfonate.
It is more highly preferred to, the tackifier are polyisobutene.
It is more highly preferred to, the copper inhibitor is oil-soluble benzotriazole.
The invention allows for a kind of above-mentioned preparation method of die cast metal heat resisting lubricating agent, comprise the following steps：
(1) each raw material is weighed according to required ratio standby；
(2) copper inhibitor and 10% polynary acid polyol ester are added in reactor first and mixed, open stirring and Heater, is heated to copper inhibitor dissolving；
(3) by the polynary acid polyol ester of the raw material after dissolving and remainder, phosphate, active sulfide aliphatic acid ester, Nonactive sulfide aliphatic acid ester, detersive, tackifier are added sequentially in reactor according to aequum, stir 30min, add stone Ink powder, stirs 60min, closes heating, is cooled to less than 50 DEG C, closes stirring；
(4) semi-finished product are ground twice using three-roll grinder, obtains finished product releasing agent.
The invention allows for a kind of above-mentioned application of die cast metal heat resisting lubricating agent, ordinary temperature is applicable not only to Environment, is also applied for 700 DEG C -800 DEG C of hot environment.
Principle of the invention is as follows：Because the flash-point of vegetable and animals oils and mineral oil is relatively low, heat resistance is poor, at high temperature Carbon distribution is easily produced, so oil based on having selected synthetic ester, impurity content is few in synthetic ester, stable physical property, heat-resisting Excellent performance has preferable wear resistence and relatively low coefficient of friction.
Additionally, large-scale casting is in casting, temperature often as high as 700-800 DEG C, hold and can't stand so by general esters Temperature high.So needing to use kollag.Molybdenum bisuphide can play lubrication work with vacuum environment in dry environments With, but hot properties is good not as graphite；The greasy property of graphite increases with the rising of temperature, but anhydrous in vacuum in graphite Environment in can not play lubrication.So by the way of both use with.Due to solid insoluble in oil in, so using clear Net agent, solid is distributed in oil in the form of micella, but considers that solids content is larger, then using three-roller grinding, makes solid Particle further reduce.
Beneficial effect：A kind of die cast metal heat resisting lubricating agent and its preparation and application that the present invention is provided, by with quality The following component for calculating is prepared from：Polynary acid polyol ester 46-81%, phosphate 1-3%, active sulfide aliphatic acid ester 1- 5%th, nonactive sulfide aliphatic acid ester 3-8%, detersive 1-5%, tackifier 2-10%, copper inhibitor 1-3%, graphite powder 5- 10%th, molybdenum bisuphide 5-10%；It is too high based on heavy castings casting temperature, from based on synthetic ester oil, kollag with And the mating reaction such as detersive, the releasing agent of preparation not only has an excellent high temperature resistant heat resistance, good stability, is provided simultaneously with Excellent greasy property, long service life and simple, safety, environmental protection, it is adaptable to various big-and-middle-sized complicated metal castings when using Stripping operation, be widely used.
Specific embodiment
