Description
Technical field
The present invention relates to mold release compositions preparing technical fields, and in particular to a kind of preparation side of oiliness antirust releasing agent
Method.
Background technology
Releasing agent is a kind of interface coating being used in the body surface that two are easy to adhesion each other, it can make object table
Face be easy to be detached from, it is smooth and clean.Releasing agent not only influences the surface property of composite material, but also whether be related to product can be with
It is removed from the mold, either how important product and mold cannot be removed from the mold if fruit product is sticked on mold,
Then product and mold can only be scrapped, therefore the effect of releasing agent is of crucial importance.
Good releasing agent should have lubrication and demolding performace good, and cooling and thermal insulation is good, and greasy property is strong, and releasing agent also has
There is heat-resisting and stress performance, be not easily decomposed or wear, releasing agent is adhered on mold and is not transfer on processed product, no
Interfere spray painting or other secondary machining operations.In addition, releasing agent should not generate pernicious gas and smog, nothing in use
It is malicious, safe, easy to operation, cost is more low.
Concrete parting agent type is various both at home and abroad at present, can according to chemical composition be divided into：It is soaps, pure oils, water quality class, molten
Agent class, polymerization species, paint class and emulsification oils.Soaps stripping result is general, and aqueous soup solution is alkaline solution, influences to mix
Solidifying soil builds surface quality after molding；It is easier to although being demoulded using the pure oils such as machine oil or used oil as release materials,
But drying time is longer after coating, and easily stains the clothing and pollution reinforcing bar of constructing operation personnel, and after concrete hardening form removal
Also usually there is oil mark on the surface of structures, affects the beauty of concrete surface, and to the later stage ornamental tape of concrete surface
Carry out very detrimental effect；Water quality class, which often applies, cannot once be used for multiple times and winter rainy season construction is unavailable；Solvent cost is high
Expensive, pollution is big；It is high to polymerize species, paint class cost, clear mould difficulty；Existing emulsification oils releasing agent emulsifying temperature is higher, uses
Emulsifier it is more, and the emulsification oil-proofness produced is poor, is susceptible to lamination, is unsuitable for long-term preservation, at
Film rear pattern plate rain wash resistance is poor, and the partial emulsifier being on the other hand wherein used in compounding causes serious pollution to the environment, and is unfavorable for big
Scale uses.
There are the following problems for releasing agent in the prior art：
（1）It needs that the noxious materials such as toluene or dimethylbenzene are added in preparation process, because it is in releasing agent preparation and application process
A large amount of volatilizations, cause pollution of the noxious material to environment, are unfavorable for health and environmental protection, and there are security risks.
A most important raw material is wax in releasing agent, however is with Brazil wax, beeswax etc. in existing releasing agent
The wax of foreign countries' production, it is of high cost；Secondly, the wax and fixed oil in releasing agent often settle after placing a period of time, make
At uneven inside mould oil, to storage and transportation, using bringing inconvenience.
Stability is poor, and temperature tolerance is relatively low, and service life is short.
Most of wax systems releasing agent using atoleine or lower melting-point microwax due to making it under the high temperature conditions（>
80℃）Stripping result substantially reduce, heat resistance is poor, it is every 1~2 time demoulding after just need to spray again, cause production efficiency big
It is big to decline.
For this purpose, being badly in need of inventing a kind of releasing agent and preparation method thereof at low cost, stripping result is good, free from environmental pollution.
Invention content

Oil phase reduces the macro-molecular protein content in ginkgo nut oil using ultrasonic wave and salting liquid demulsification processing extraction ginkgo nut oil,
Make the oxidation stability of oil phase be influenced to reduce by environment acid-base value and temperature, in ginkgo nut oil unsaturated fatty acid content compared with
Height, it is strong to the barrier absorbability of oxygen in air after oiliness antirust releasing agent is applied to metal surface, and ginkgo nut oil can be with part
The metallic divalent cations aoxidized are chelated, and adhesive force of the oiliness antirust releasing agent to metal is improved, and metal ion can be slowly
The unsaturated fatty acid aoxidized is restored, benign cycle is formed, oiliness antirust releasing agent is made to be always maintained at stronger reducing property,
To make the rust-proof life of oiliness antirust releasing agent extend；
（2）The parent corrosion inhibiter that the present invention is mixed into oiliness antirust releasing agent is a kind of Mannich base, female after quaternary ammoniated
Polar group of the body corrosion inhibiter centered on the larger nitrogen-atoms of electronegativity, polar group hydrophily is very strong, when it is touched
After metal surface, there are physisorptions with metal, form adsorption layer, and at the same time, non-polar group is far from metal
Direction, form hydrophobicity film, change the state of charge of metal surface, increase rotten candle and get rusty the activation energy of reaction, make rust
Change reaction to be difficult to carry out, cation group is carried in parent corrosion inhibiter, to the concentration of metal ions of oiliness antirust releasing agent chelating
Have inhibition, can reduction of the catalytic metal ion to saturated fatty acid, make the oil phase unsaturated lipid of oiliness antirust releasing agent
Fat acid content is maintained at higher state, and to promote the rustless property of oiliness antirust releasing agent, form a film antirust agent energy and ginkgo nut
A small amount of protein combines in oil, and powdery release layer is formed in annealing process, convenient for demoulding, has a extensive future.
