Abstract
The present invention provides a solid high-temperature lubricant for extruding aluminium sections and a preparation method thereof. The lubricant comprises the components of a solid lubricant, a high melting point organic lubricant, a softening point regulating agent, a high melting point adhesive, a fire resistance additive and a corrosion inhibitor. The components are melted, mixed, cast, sliced, stamped and shaped. The lubricant is solid at room temperature, and when the lubricant is in contact with a high temperature position which needs lubricating, the lubricant is immediately melted into a lubricating film which firmly adheres. The present invention has the advantages of convenient operation, high utilization rate, no environmental pollution and avoidance of fire hazard generation.
Description
The present invention relates to solid-state high temperature lubricant of aluminium section bar extruding usefulness and preparation method thereof, be specifically related to be used for aluminium section bar container end face, cutting edge and separate solid-state high temperature lubricant of extruding separation pad and preparation method thereof.
Traditional aluminum extrusion process is unlubricated extruding, can adhere to aluminium at extruding simple end face and cutting edge place inevitably, and be difficult to separate extruding separate pad and shear press surplus.Prior art adopts aqueous (for example rape oil adds graphite) or semi-fluid shape (for example butter adds graphite) lubricant, though can overcome above-mentioned shortcoming, satisfy the lubricating requirement of aluminum extrusion process, but obviously have that operation inconvenience, lubricant effective rate of utilization are low, the cigarette big flame is long in the use, not only contaminate environment but also easy presence of fire, the not high shortcoming of lubricating efficiency.
The present invention aims to provide a kind of new aluminium section bar and pushes solid-state high temperature lubricant of usefulness and preparation method thereof.It is solid-state that this lubricant at room temperature is, and is fused into the liquid good lubricant film of high temperature lubricating performance when contacting with required lubricated high temperature position immediately, not only easy to operate, utilization ratio is high, and free from environmental pollution, avoid presence of fire.
The objective of the invention is to realize by following proposal.
Solid-state high temperature lubricant of the present invention comprises solid lubricant, high-melting-point organic lubricant, high-melting-point adhesive agent, softening temperature conditioning agent, corrosion inhibitor and anti-combustion additive, and wherein the weight percent of each component is:
Solid lubricant 5--30%
High-melting-point organic lubricant 10--60%
High-melting-point adhesive agent 5--40%
Softening temperature conditioning agent 6--40%
Corrosion inhibitor 0--5%
Anti-combustion additive 0--5%.The optimum weight per-cent of described each component is:
Solid lubricant 10%
High-melting-point organic lubricant 40.4%
High-melting-point adhesive agent 29.2%
Softening temperature conditioning agent 20%
Corrosion inhibitor 0.2%
Anti-combustion additive 0.2% solid lubricant can be selected from one or more mixture of graphite, molybdenumdisulphide.The high-melting-point organic lubricant can be selected from high-melting-point grease, pitch or synthetic lubricant.The softening temperature conditioning agent can be selected from high-melting-point alkane, titanium dioxide or solid lubricant.The high-melting-point adhesive agent can comprise pitch 5--50% (weight), high-melting-point alkane 10--40% (weight), high-melting-point grease 0--10% (weight) and polymkeric substance 0--5% (weight).Anti-combustion additive can be selected from phosphoric acid ester, borax or graphite.Corrosion inhibitor is a high basicity mahogany sulfonate.
The viscosity of described graphite or molybdenumdisulphide is greater than 200 orders, preferred 320 orders.The high-melting-point grease can be selected from stearic acid or tallow, preferred tallow.Pitch is the pitch of high softening-point and deep oxidation, preferred 10
#Pitch.High-melting-point alkane is coarse-grain or the microcrystalline wax of carbonatoms 20--50, and fusing point 35--100 ℃, polymkeric substance is optional from polyisobutene or polyethylene or its mixture, and synthetic lubricant can be selected from anti-material more than 200 ℃, for example polyphenylene oxide.
Solid lubricant and high-melting-point organic lubricant are for satisfying the lubricity requirement under the condition of different temperatures, and solid lubricant has the function as the mineral filler of regulating softening temperature simultaneously concurrently.The high-melting-point adhesive agent has lubricant of the present invention at room temperature to be solid-state, when needing the lubricant housings contact with pyritous, promptly is molten into the performance of liquid lubricant film, and sticks to the need lubricant housings securely.The softening temperature conditioning agent makes lubricant of the present invention in use have suitable melting rate, with the time requirement that guarantee to adopt the application process operation and the requirement of usage quantity, has not only melted but also not following.Anti-combustion additive can make that cigarette is few, flame short, reduces the degree of catching fire.Corrosion inhibitor is in order to reduce corrosion.
The preparation method of solid lubricant of the present invention comprises the steps:
1. raw material is prepared: each component of solid-state high temperature lubricant is standby by the proportioning weighing;
2. melt-blended: as the organic composition of high-melting-point organic lubricant, adhesive agent to be put into heating kettle be heated to fusing, remove the high volatile volatile material through abundant oxidation, treat its all organic composition of fusing back adding softening temperature conditioning agent, slowly be stirred to whole fusings, restir 5 minutes stops heating, the inorganic components that adds inorganic components, solid lubricant and the softening temperature conditioning agent of adhesive agent, stir, between 100--250 ℃, add corrosion inhibitor and anti-combustion additive, stir thereupon;
3. cast: the stirring said mixture is reduced between 100--90 ℃ until temperature and is poured into a mould, and teeming temperature keeps 96 ± 2 ℃;
4. stripping and slicing pressing mold: molding when temperature is reduced to 60--20 ℃, stripping and slicing about 40 ℃, place press molding machine to be pressed into the size of requirement stripping and slicing.
Solid-state high temperature lubricant of the present invention has the unrivaled advantage of existing lubricant, it can satisfy the lubricating requirement under the differing temps, lubricity is good, be solid-state at normal temperatures, needing the lubricant housings to contact with pyritous promptly is fused into the firm lubricant film of adhesion, just is frozen into solid-state in case leave the contact site.Obviously, the high temperature lubricating performance is good, easy to operate, utilization ratio is high, do not pollute the environment, avoid presence of fire, and is fool proof reliable.
Describe the present invention below in conjunction with embodiment, but not limited thereto.The proportioning of described each component of lubricant can be done suitably to adjust by the temperature of required lubricant housings.Embodiment 1
