Detailed description of the invention
The present invention is described in further detail below, with make those skilled in the art with reference to description word can evidence
To implement.
This case proposes the fire-retardant power distribution cabinet of an embodiment, and including cabinet, it is sequentially provided with finishing coat, the first steel from top to bottom
Flaggy, the first adhesive layer, layer of polyurethane, the second adhesive layer, the second steel plate layer and flame-retardant layer；
Wherein, finishing coat is the inner surface of cabinet, and finishing coat includes the material of following weight portion:
The number-average molecular weight of epoxy resin used by this case is both preferably 3500～3600g/mol.
Acetylene-hydroxyethylacrylate copolymer is random copolymer, and all of copolymer of this case is all random copolymer, it
Synthetic method belong to prior art, general olefin polymerization conditions is used equally to synthesize these copolymers.The technology of this case
In scheme, acetylene-hydroxyethylacrylate copolymer can improve the heat-proof quality of cabinet, and can tolerate difference variation repeatedly, its
The limit bears the temperature difference up to 240 DEG C, and in particular, it can tolerate temperature and repeatedly changes, in it between-90 DEG C～150 DEG C
Portion is non-sclerous non-brittle.But the composition in acetylene-hydroxyethylacrylate copolymer should be defined because with this copolymer structure class
As ethylene-acrylic acid hydroxyl methacrylate copolymers, acetylene-ethyl acrylate copolymer, acetylene-methyl acrylate copolymer and benzene second
Alkynes-hydroxyethylacrylate copolymer etc. does not all have above-mentioned functions.Meanwhile, the addition of acetylene-hydroxyethylacrylate copolymer is also
Should be defined, its addition can affect the heat-proof quality of final cabinet.
Nitrodracylic acid butyl ester can also be used for improving the heat-proof quality of cabinet, and it can improve the low temperature resistant resisting fatigue of cabinet
Characteristic so that cabinet can the bigger temperature difference of tolerance repeatedly, meanwhile, it can improve the overall structure toughness of cabinet, thus can
To increase the structural stability of cabinet further, increase the service life of cabinet.But it is similar to Nitrodracylic acid butyl ester structure
Methyl p-nitrobenzoate, ethyl p-nitrobenzoate, o-Carboxynitrobenzene butyl ester etc. all there is no this function.Therefore, right
Nitrobenzoyl acid butyl ester and addition thereof should be restricted.
The introducing of Dineodymium trioxide can increase the toughness of finishing coat, crack resistance and frost resistance, makes finishing coat at different temperatures environment
Under also can possess preferable bond strength.But other metal-oxides such as ytterbium oxide, yittrium oxide, silicon oxide, titanium oxide, zirconium oxide
