Embodiment 1
[0028] The preparation process of the copper alloy-based diatomite pumice iron oxide composite material of the present invention is as follows:
[0029] a. Preparation of diatomite pumice iron oxide compound: first put ferric chloride and ammonium ferrous sulfate into a hydrothermal container with Teflon lining, add water to dissolve (add a small amount of water until dissolved), and then Pack diatomite and pumice mixture, the size of diatomite particle is 0.2mm, the size of pumice particle is 0.6mm, the weight ratio of diatomite and pumice in the diatomite pumice mixture is 0.5: 1, stirring the above materials reaches 4-8min, the weight ratio of the mixture of ferric chloride, ammonium ferrous sulfate and diatomite pumice is 1:1:1, after the stirring is completed, put the stirring material in an oven at 240°C for 3 hours, then cool naturally to obtain diatomite Iron oxide complex;
[0030] b. Preparation of iron fiber: Cu is 0.003% by weight percentage, Sm is 0.003%, and the...

[0035] a. Preparation of diatomite pumice iron oxide compound: the weight ratio of ferric chloride, ferrous ammonium sulfate and diatomite pumice mixture is 1:1:2, the weight of diatomite and pumice in the diatomite pumice mixture The ratio was 1:1, the diatomaceous earth particles had a size of 0.4 mm, and the pumice particles had a size of 1 mm.
[0036] B. the preparation of iron fiber: containing Cu by weight percentage is 0.09%, Sm is 0.006%, and the rest is Fe to carry out batching;
[0037] c. Preparation of the composite prefabricated body: control the volume percentage of the diatomite pumice iron oxide composite to 45-50% of the composite material.
[0038]d. Preparation of copper alloy liquid: the weight percentage of copper alloy components is 5% for Al, 0.05% for Ti, 1% for Sn, 0.01% for Nd, and the rest is Cu.
[0039] The preparation process is the same as in Example 1.
