Description
Technical field
The invention belongs to ejection technique field, it is related to a kind of aluminium alloy alkalinity and squeezes release agent and preparation method thereof.
Background technique
Release agent be intermetallic composite coating squeeze, casting, the important auxiliary material in forging process, squeeze in intermetallic composite coating, casting,
Play this important role in forging processing technology, molding situation, finish and die life of die surface etc. with demoulding
Agent is closely related.
Currently, there is certain deficiencies for the release agent used both at home and abroad, and such as: aluminium powder, the ductility of copper powder, film forming
Property it is poor, usage amount is difficult to form fine and close film when few, influences stripping result, easily forms stack layer when usage amount is big, influences
The size and precision of workpiece；The stripping result of molybdenum disulfide is poor, complicated component, contains environmentally harmful organic solvent；And it goes
Graphite commonly used in the trade itself is conductive, easily causes the short circuit of electrical equipment in process of production, and graphite is in high temperature
It squeezes, cast, being atomized in forging process and drift everywhere, generating graphite dust pollution, the body for seriously endangering operator is strong
Health；Other release agents there is also die surface packing phenomenon it is serious, be not easy to the defects of cleaning, need to rely on manually into
The processing of row wiper, expends biggish human cost.
It is manually to smear, and contain a large amount of graphite, working environment in release agent that traditional aluminium bar, which squeezes thimble release agent,
It is very poor, labour cost is not only created in production, also workpiece is allowed to be difficult to clean.And the method for using spraying, it can even application
At machined surface, in workpiece process, it is easy to form the film of powdery difficulty cleaning in machined surface.
Summary of the invention
In view of disadvantages described above, the purpose of the present invention is overcome the deficiencies of the prior art and provide a kind of aluminium alloy alkalinity extruding
Release agent and preparation method thereof.
To achieve the above object, a kind of aluminium alloy alkalinity provided by the invention squeezes release agent, which is characterized in that includes pine
Fragrant salt, the abietate account for the 1-30% of total weight percentages of components.
The weight fraction ratio of abietate component below is prepared:
Rosin 100；
Sodium hydroxide and/or potassium hydroxide 50-100.
The preparation method of the abietate, it is characterised in that: sodium hydroxide and/or potassium hydroxide are first dissolved in 1-3
In the water of times weight, using its heat of solution, rosin is added, heating temperature is kept to be not less than 90 DEG C, stirs into paste, observes nothing
When obvious foreign matter, as abietate.
Rosin is natural materials, and prepared abietate tool is a bit sticky and lubricity and release agent can be enhanced
Peel strength.
In order to enhance the film strength and peel strength that aluminium alloy alkalinity squeezes release agent, weight percent 1- can be added
10% phthalate or M-phthalic acid salt or terephthalate or trimesic acid salt or trimellitic acid
Salt or Pyromellitic Acid salt.
The phthalate is anti-by phthalic acid or phthalic anhydride and sodium hydroxide or potassium hydroxide
It should be prepared.
The M-phthalic acid salt is prepared by M-phthalic acid and the reaction of sodium hydroxide or potassium hydroxide.
The phthalate is prepared by phthalic acid and the reaction of sodium hydroxide or potassium hydroxide.
The trimesic acid salt is prepared by trimesic acid and the reaction of sodium hydroxide or potassium hydroxide.
The trimellitic acid salt is prepared by trimellitic acid and the reaction of sodium hydroxide or potassium hydroxide.
The Pyromellitic Acid salt is anti-by Pyromellitic Acid or pyromellitic dianhydride and sodium hydroxide or potassium hydroxide
It should be prepared.
In order to increase the stability that aluminium alloy alkalinity squeezes release agent stoste, it can be added weight percent 0.1-2%'s
Polyacrylamide or Sodium Polyacrylate or sylvite or sodium polymethacrylate or sylvite.
In order to increase the dispersibility and demoulding efficiency that aluminium alloy alkalinity squeezes release agent stoste, weight percent can be added
The cellulose ether (hydroxyethylmethylcellulose) or sodium lignin sulfonate of 0.1-2%.
In order to increase the stability that aluminium alloy alkalinity squeezes release agent stoste, it can be added weight percent 0.5-2%'s
Nonionic surfactant.
The optional fatty alcohol polyoxyethylene ether of the nonionic surfactant, preferably marque have: AEO-6, AEO-
9, AEO-10, AEO-15 one or more mixture；Or sorbitan fatty acid polyoxyethylene ether, preferably marque have:
One or more of Tween-20, Tween-40, Tween-60, Tween-80, Tween-85 mixture.
In addition, a kind of aluminium alloy alkalinity provided by the invention squeezes release agent, which is characterized in that by following weight percent
Component be fabricated:
The benzoic acids substance are as follows: phthalic acid, phthalic anhydride, M-phthalic acid, terephthalic acid (TPA),
One or more of benzenetricarboxylic acid, trimellitic acid, Pyromellitic Acid, pyromellitic dianhydride mixture.
In addition the present invention also provides the preparation methods that above-mentioned aluminium alloy alkalinity squeezes release agent, it is characterised in that: by hydrogen
Sodium oxide molybdena is dissolved in the water, and rosin, benzoic acids substance is added, and translucent, addition is stirred until homogeneous at a temperature of 90-100 DEG C
Sodium polymethacrylate, sodium lignin sulfonate, nonionic surfactant continue stirring to it is transparent or semitransparent when, it is as a kind of
Aluminium alloy alkalinity squeezes release agent.
Above-mentioned aluminium alloy alkalinity squeeze release agent using when add 3-10 times of water be sprayed on squeeze on stripper apparatus mandril or
