2 parts of base sodium sulphate, 1 part of urea, the molecular weight of the end alkenyl polyoxyethylene ether are 2500.) it is applied to as shown in Figure 1 prefabricated
In component production (prefabricated components include ontology 1, are provided with 100 2 structures of protrusion on 1 side wall of ontology), to gained prefabricated components
Statistic of attribute is carried out, the results are shown in Table 1：
Table 1：Prefabricated components statistic of attribute situation table
From upper table 1 as can be seen that Examples 1 to 7 provided by release agent be able to achieve it is prefabricated to Ardealite concrete
The demoulding of component, and moldability is excellent, the double stearic amide powder of vinyl and graphene powder content increase, and can effectively mention
The quality of high prefabricated components, demoulding are also increasingly easy therewith, and the double stearic amide powder of medium vinyl are thinner, release agent
Effect is better, and the quality of prefabricated components is also better；Particularly, it is found no on all prefabricated components molds and is stained with grey phenomenon, said
The double stearic amide powder of bright addition vinyl and graphene powder can make release agent resist dust to infect；
Comparative example 8, the results showed that：It is serious to be stained with grey phenomenon, release agent is not suitable for irregular prefabricated in embodiment 8
Component (bulge rupture 48%), because vegetable oil can cause film forming uneven because self gravity drops, and speed is slow；Because
Film forming is uneven, causes it that cannot preferably completely cut off mold and prefabricated components itself, to need bigger knockout press, this also causes
The quality degradations of prefabricated components, defect is serious, and the release agent in Examples 1 to 7 is much better than this；
Compare control group, the results showed that：It is stained with that grey phenomenon is serious, the quality of prefabricated components is better than embodiment 8, but is inferior to implement
Example 1~7；The analysis of causes is as follows：
Because wherein aqueous, water translocation needs the time longer (it also needs the time to make moisture sufficiently dry), results in
Film forming speed is slower, it may be possible to due to the complex production for not being suitable for irregular prefabricated components of ingredient therein, take off
Mould power is all larger than required knockout press in Examples 1 to 7, and bulge rupture situation is serious (greater than in embodiment 1 more than 2 times),
There are more defects and its surface, there are more air bubble-shaped defects；Therefore, the release agent provided in Examples 1 to 7 can be with
It is applied to the production of the especially irregular prefabricated components of prefabricated components more excellently.
Above embodiments 1~8 and control group show to add the double stearic amide powder of vinyl and graphite in edible oil
Alkene powder can effectively avoid vegetable oil because dropping caused by gravity, accelerate release agent in the uniform expansion of die surface, simultaneously
The increase of the double stearic amide powder of vinyl and graphene powder additive amount can be improved the quality of release agent and improve by it
The quality of the prefabricated components of production：When the ratio of vegetable oil, the double stearic amide powder of vinyl and graphene powder reaches 30：
2：When 1, release agent and the prefabricated components quality made by it are to be optimal state, accordingly, it is considered to which cost factor no longer needs to do
Increase operation；Meanwhile the double stearic amide powder sizes of vinyl in 350 mesh but also their quality is best, consider cost
Factor is operated without increase is done again.
After carrying out Examples 1 to 8 and control group test, by the unified storage of 9 groups of molds used in 1~8 and control group
(35 DEG C of temperature, 95 ° of relative humidity) observe die surface and corrode situation after 15 days, the results are shown in Table 2：

| Embodiment 7 | Surface is without visible corrosion |
| Embodiment 8 | Surface has corrosion in flakes (area is greater than 20%) |
| Control group | Surface corrosion is serious (area is greater than 50%) |
From Table 2, it can be seen that it is (wherein, real not occur corrosion situation after Examples 1 to 7 mould therefor is stored 15 days
Apply example 1 and corrode area less than 1%, can be ignored substantially), there are more serious corrosion feelings after storing 15 days in 8 mould therefor of embodiment
Condition, area is larger (being greater than 20%), causes to seriously affect to reusing for mold, and control group mould therefor rust surface
Product is greater than 50%, and corrosion is serious, and mold can not be used again；The table of comparisons 1 is as a result, mold corrosion situation and prefabricated components surface
Smooth degree is corresponding：Examples 1 to 7 mold and prefabricated components all have higher quality, the mold of embodiment 8 and control group
Occur corrosion and blibbing shape defect respectively with prefabricated components, this illustrates the double stearic amides of the vinyl that the present invention adds
Better buffer action can be played to substances such as sulphur, phosphorus in Ardealite concrete with graphene, can be improved prefabricated components
