Example 2
This example provides a recyclable carrying case substantially as in example 1, except that the following raw materials are used: 100 parts of polymer base material (70 parts of PP (EPC30R-H), 30 parts of HDPE (5200B)), 5 parts of vapor phase corrosion inhibitor (4- (N, N-di-N-butyl) -amine methylmorpholine, DBM) and 0.5 part of black color masterbatch (Jiasheng).
Example 3
This example provides a recyclable carrying case substantially as in example 1, except that the following raw materials are used: 100 parts of polymer base material (wherein, 70 parts of PP (EPC30R-H) and 30 parts of HDPE (5200B)), 2 parts of vapor phase corrosion inhibitor (4- (N, N-di-N-butyl) -amine methylmorpholine, DBM) and 2 parts of black color masterbatch (Jiasheng).
Example 4
This example provides a recyclable carrying case substantially as in example 1, except that the following raw materials are used: 100 parts of polymer base material (wherein, 75 parts of PP (EPC30R-H) and 25 parts of HDPE (5200B)), 2 parts of vapor phase corrosion inhibitor (4- (N, N-di-N-butyl) -amine methylmorpholine, DBM) and 2 parts of black color masterbatch (Jiasheng).
Example 5
This example provides a recyclable carrying case substantially as in example 1, except that the following raw materials are used: 100 parts of polymer base material (72.5 parts of PP (EPC30R-H), 27.5 parts of HDPE (5200B)), 2 parts of vapor phase corrosion inhibitor (4- (N, N-di-N-butyl) -amine methylmorpholine, DBM) and 2 parts of black master batch (Jiasheng).
Example 6
This example provides a recyclable cartridge substantially as described in example 3, except that the starting materials used also include 1 part 1-methyl-4-chloromethylimidazole and 0.5 part sodium tert-butoxide; and firstly adding 1-methyl-4-chloromethylimidazole and sodium tert-butoxide into a preheated double-screw extruder for mixing, then adding into a polymer base material, and finally adding a gas phase corrosion inhibitor.
Comparative example 1
This example provides a recyclable carrying case substantially as described in example 6, except that dicyclohexylamine nitrite is used as the vapor phase corrosion inhibitor.
The cases (steel shells, 100mm × 60mm × 10mm, 1mm in wall thickness, 12) for mobile phone batteries loaded in the loading cases of examples 1 to 6 and comparative example 1 were used, and sealed for 30 days to perform sealing experiments, and the sustained release efficiencies were respectively 89.5%, 91.8%, 91.5%, 93.2% and 85.0%. It can be seen that the slow release effect of the loading box adopting 4- (N, N-di-N-butyl) -amine methylmorpholine is superior to that of dicyclohexylamine nitrite; the slow release effect of the vapor phase corrosion inhibitor is basically not influenced by the change of the components of the polymer base material within a certain range; the best effect was obtained in example 6 with a reduced amount of the vapor phase corrosion inhibitor, probably because the imidazole alkyl group was grafted to the N atom of morpholine during the extrusion mixing process to change its steric configuration and to exhibit weak electric property, thereby improving its slow release effect.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention; while the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
