Description
Technical field
The present invention relates to multicoat Material Fields, in particular to waterproof coating material and its system of the kind for nail shooting pill shell case
Preparation Method
Background technique
Nail shooting pill belongs to non-combat bullet, and inside contains gunpowder, and lethality is bigger, is usually used, is used on finishing circle
It measures very big.The shell case main material of nail shooting pill is copper material, belongs to metal material, it is well known that by surrounding medium
Under the action of, such material is easy to happen damage, it is serious can seriously corroded, metal material by surrounding medium effect and damage
It is bad, referred to as metal erosion.Metal erosion is relatively common phenomenon, is probed into the reason is that chemistry has occurred on the interface of metal
Or electrochemistry heterogeneous reaction, so that metal is converted into the state of being oxidized, this can significantly reduce the power such as the intensity of metal material, plasticity
Performance is learned, destroys the original shape of object, increases abrasion, so nail shooting pill is in actual use, copper shell case is without appointing
If where is managed, meeting surface is corroded, and influences actual use.
Currently, main solution is to coat one layer of waterproof membrane on the surface of copper shell case, so that copper shell case and sky
Gas or water isolation,
Summary of the invention
The waterproof coating and preparation method thereof that the object of the present invention is to provide a kind of for nail shooting pill shell case, this type coating are used
In nail shooting pill shell case, the compactness height and waterproof performance of coating are excellent.
In order to solve the above technical problems, the object of the present invention is achieved like this:
A kind of waterproof coating material for nail shooting pill shell case, it is characterised in that: by as follows according to the raw material group of parts by weight
At: 15~20 parts of Versamid, 0.5~1.5 part of polyaniline, 34~40 parts of epoxy resin, 3~5 parts of ethyl alcohol.
Preferably, the epoxy resin is epoxy resin E-51.
Preferably, the polyamide is polyamide -651 or/and polyamide -650.
Second object of the present invention is realized by following technical scheme:
The preparation method of waterproof coating material for nail shooting pill shell case is carried out according to step once:
1) required polyamide, polyaniline in the ball mill, is proportionally added, sets drum's speed of rotation as 360r/
Min, ball milling 10 hours.
2) then the mixture after ball milling is put in centrifuge, is centrifuged 15 minutes, obtains upper layer mixture.
3) mixture is mixed with ethanol in proper amount, is filtered after mixing.
4) component obtained in step 3) is uniformly mixed with epoxy resin.
The waterproof coating material of nail shooting pill shell case prepared by the present invention, using epoxy resin E-51 as film forming matter, curing agent
For polyamide -651, epoxy resin/polyamide system waterproof coating is prepared under normal temperature conditions, due to such system chemistry
Structure makes the compactness height of coating and waterproof performance is excellent.During prepares coating, using the side of centrifuge separation
Method, has separated that its middle-molecular-weihydroxyethyl is larger, the polymeric particles of reunion, be conducive to be formulated so in the coating it is effective uniformly point
It dissipates, so that the adhesion property of coating improves.
